The temperature at midnight is shown. The outside temperature decreases 2.3 C over the next two hours. What is the outside temperature at 2 A.M. ?
Answer:
Outside temperature at 2 A.M = -33.2°C
Step-by-step explanation:
Given:
Temperature at 12:00 midnight (outside) = -30.9°C
Rate of decreases = - 2.3°C per two hour
Find:
Outside temperature at 2 A.M
Computation:
Outside temperature at 2 A.M = Temperature at 12:00 midnight (outside) + Rate of decreases
Outside temperature at 2 A.M = -30.9°C + (- 2.3°C)
Outside temperature at 2 A.M = -33.2°C

Ahmad the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Monday there were clients 3 who did Plan A and 2 who did Plan B. On Tuesday there were 5 clients who did Plan A and 6 who did Plan B. Ahmad trained his Monday clients for a total of 3 hours and his Tuesday clients for a total of 7 hours. How long does each of the workout plans last? please help
Answer:
Plan A last for 30 minutes
Plan B last for 45 minutes
Step-by-step explanation:
There are two plans:
Plan A
Plan B
Monday
Plan A=3 clients
Plan B=2 clients
Total hours=3
Tuesday
Plan A=5 clients
Plan B=6 clients
Total hours=7
The equation for the unknown
3A + 2B=3 (1)
5A + 6B=7 (2)
Multiply (1) by 3 and (2) by (1)
9A + 6B=9 (3)
5A + 6B=7 (4)
Subtract (4) from (3)
4A=2
Divide both sides by 4
4A/4 = 2/4
A=1/2 hours
Substitute A=1/2 into (1)
3A + 2B=3
3(1/2) +2B=3
3/2 + 2B=3
2B= 3 - 3/2
2B= 6-3/2
2B=3/2
Divide both sides by 2
B=3/2÷2
=3/2×1/2
B=3/4 hours
A=1/2 hours
B=3/4 hours
60 minutes=1 hour
A=1/2 hours
1/2 × 60 minutes
=60/2
=30 minutes
B=3/4 hours
=3/4×60 minutes
=180/4
=45 minutes
Plan A last for 30 minutes
Plan B last for 45 minutes
Please help ASAP. The question is down below.
Answer:
Question 1.
Option A: 2m
Question 2
Option D: (1, 1) minimum point
Step-by-step explanation:
Question 1.
Let the original length of the garden (before expansion) be = x
The new length of the garden will be x + 10m
Recall that the garden has a square geometry. That means that its area is obtained by squaring any of its sides.
This means that [tex](x +10)^2 = 144[/tex]
We can now solve for x
[tex](x +10)^2 = 144\\x^2 +20x +100 = 144\\x^2 + 20x =44\\x^2 + 20x - 44=0\\x = 2 or -22[/tex]
x cannot be a negative number, so the original length of a side of the garden is 2m. Option A
Question 2:
The coordinates of the vertex of the graph (turning point) are (x, y) [1,1]
To know whether it is a minimum or maximum point, we will have to check the coefficient of [tex]x^2[/tex] in the equation [tex]y = x^2-2x+2[/tex]
The coefficient of [tex]x^2[/tex] in the equation is 1. (If no number is present, just know that the coefficient is a one).
If the coefficient is positive, then the point is a minimum point. However, if it is negative, then the point is a maximum point.
Our coefficient is positive hence, the graph has a minimum point.

Answer:
140°
Step-by-step explanation:
[tex] \because m\widehat{BG} = 360\degree - m\widehat{GCB} \\
\therefore m\widehat{BG} = 360\degree - 300\degree \\
\therefore m\widehat{BG} = 60\degree \\
\because m\widehat{BGD} = m\widehat{BG}
+m\widehat{GD}\\
\therefore m\widehat{BGD} = 80\degree+60\degree\\
\therefore m\widehat{BGD} = 140\degree\\
\because m\angle BAD = m\widehat{BGD} \\

Given \qquad m \angle LONm∠LONm, angle, L, O, N is a straight angle. \qquad m \angle MON = 8x - 13^\circm∠MON=8x−13 ∘ m, angle, M, O, N, equals, 8, x, minus, 13, degrees \qquad m \angle LOM = 7x - 17^\circm∠LOM=7x−17 ∘ m, angle, L, O, M, equals, 7, x, minus, 17, degrees Find m\angle MONm∠MONm, angle, M, O, N:
Answer:
[tex] \boxed{99°}[/tex]Step-by-step explanation:
m<MON = 8x - 13°
m<LOM = 7x - 17°
To find : m <MON
First, we have to find the value of x :
Create an equation
[tex] \mathrm{8x - 13 + 7x - 17 = 180}[/tex] ( sum of angle in straight line )
Collect like terms
[tex] \mathrm{15x - 13 - 17 = 180}[/tex]
Calculate
[tex] \mathrm{15x - 30 = 180}[/tex]
Move constant to R.H.S and change its sign
[tex] \mathrm{15x = 180 + 30}[/tex]
Calculate the sum
[tex] \mathrm{15x = 210}[/tex]
Divide both sides of the equation by 15
[tex] \mathrm{ \frac{15x}{15} = \frac{210}{15} }[/tex]
Calculate
[tex] \mathrm{x = 14}[/tex]
Now, let's find the value of m<MON
[tex] \mathrm{8x - 13}[/tex]
Plug the value of x
[tex] \mathrm{ = 8 \times 14 - 13}[/tex]
Calculate the product
[tex] \mathrm{ = 112 - 13}[/tex]
Calculate the difference
[tex] \mathrm{ = 99}[/tex] °

Answer:
Range : { -5,1,7}
Step-by-step explanation:
Take the values in the domain and substitute into the equation
x = -3
y = -2(-3) +1 = 6+1 =7
x = 0
y = -2(0) +1 = 0+1 =1
x = 3
y = -2(3) +1 = -6+1 =-5
The range is the y values
We put then in order from smallest to largest
Range : { -5,1,7}
Which function has a range of y < 3? y=3(2)x y = 3(3)x y = -(2)x+ 3 y = (2)x-3
Answer:
Third option is the correct answer
[tex]y = -(2)x+ 3[/tex]
Step-by-step explanation:
Given functions are:
[tex]y=3(2)x\\ y = 3(3)x\\ y = -(2)x+ 3\\ y = (2)x-3[/tex]
To find:
The function which has a range [tex]y <3[/tex] ?
Solution:
First of all, let us learn about the terms Domain and Range for a function:
[tex]y = f(x)[/tex]
Domain is the value of [tex]x[/tex] which is given as input to the function and gives a valid value of output as [tex]y[/tex] (i.e. function is defined).
Range of a function is the value [tex]y[/tex] that comes as output when given a valid value of [tex]x[/tex] as input.
Now, let us consider the given options above.
Third option is the correct answer.
[tex]y = -(2)x+ 3[/tex]
As we can see, [tex](2)x[/tex] is subtracted from 3 so [tex]y[/tex] will have a value which is lesser than 3.
i.e. range will be [tex]y <3[/tex].
No other function has such condition present in it.
[tex]y = -(2)x+ 3[/tex] is the correct answer.

Which point represents the opposite of 0 on the number line? A B C D E
Answer:
C: 0
Step-by-step explanation:
Let's use 1 for an example first. The opposite of 1 is -1. 2 = -2, 3 = -3, and so on. Since there is no such thing as -0, our answer would be C, 0. It is not -5, -2, 2, or 7 because those are not the negatives of 0.

2. Describe two methods to determine whether ratios form a proportion.
Answer:
1. Write both ratios as fractions and reduce them completely. If they are the same fraction, the ratios form a proportion.
2. Write both ratios as fractions. Do the cross products by multiplying the denominator of each fraction by the numerator of the other fraction. If the cross products are equal, the ratios form a proportion.
two years ago a woman wad 7 times as old as her daughter, but in 3 years time she would be x times as old as the girl. how old are they now?
Answer:
The present age of the woman is 37 years and her daughter is 7 years
Step-by-step explanation:
two years ago a woman was 7 times old as her daughter, but in 3 years time she would be 4 times old as the girl. how old are they now
Two years ago a woman wad 7 times as old as her daughter
Let her daughter=x-2
The woman=y-2
x-2
7(y-2)=7y-14
x-2=7y-14
x-7y=-14+2
x-7y= -12 (1)
but in 3 years time she would be 4 times as old as the girl.
x+3
y+3
x+3
4(y+3)=4y+12
x+3=4y+12
x-4y=12-3
x-4y=9. (2)
x-7y= -12 (1)
x-4y=9. (2)
Subtract (1) from (2)
4y-(-7y)=9-(-12)
-4y+7y=9+12
3y=21
y=21/3
y=7
Substitute
y=7 into (1)
x-7y= -12
x-7(7)=-12
x-49=-12
x= -12+49
=37
The present age of the woman is 37 years and her daughter is 7 years

Mildred’s salary has increased from £24,600 to £25,338. By what percentage has her salary increase?
Answer:
The answer is 3%Step-by-step explanation:
To find the percentage increase we use the formula
[tex]Percentage \: change = \frac{ change}{original \: quantity} \times 100[/tex]
To find the change subtract the smaller quantity from the bigger one
From the question
original price = $24,600
Current price = $ 25,338
Change = $25,338 - $ 24,600
Change = $ 738
So the percentage increase is
[tex] \frac{738}{24600} \times 100[/tex]
[tex] = \frac{3}{100} \times 100[/tex]
We have the final answer as
Percentage increase = 3%Hope this helps you
Una profesora compra 28 manzanas para compartir con sus estudiantes; al día siguiente revisa la cesta con las frutas y ve que se le han dañado 2/7 del total de manzanas que había comprado. Para reponer las frutas dañadas ella debe comprar
Answer:
La profesora debe comprar 8 manzanas para reponer la cesta de frutas.
Step-by-step explanation:
La profesora debe reponer la cesta de frutas por la cantidad de manzanas que se encuentran dañadas. La cantidad de manzanas dañadas es igual a las dos séptimas partes del total de manzanas. Es decir:
[tex]x = \frac{2}{7} \times (28\,manzanas)[/tex]
[tex]x = \frac{56\,manzanas}{7}[/tex]
[tex]x = 8\,manzanas[/tex]
La profesora debe comprar 8 manzanas para reponer la cesta de frutas.
A pyramid has a square base with an area of 169 ft.² what is the perimeter of the base of the pyramid
Answer:
52
Step-by-step explanation:
Square root of 169 is 13.
SInce it is a square all sides are same length. So you could do 13x4 or 13+13+13+13. Both will equal to 52.
The perimeter of the base of the pyramid is 52 square feet.
Given that,
The pyramid contains a square base having an area of 169 square feet.
We know that,
Area of the square = side^2
169 = side^2
So, the side is 13 feet.
So, the perimeter should be
= 4 × sides
= 4 × 13
= 52 feet
Therefore, we can conclude that The perimeter of the base of the pyramid is 52 square feet.

Answer:
24.99 cm
Step-by-step explanation:
We are provided with the radius of the circle so we can use that to solve for the circumference(perimeter) of the circle. The formula to solve for the circumference is 2*pi*r.
2*pi*7 = 14pi = 43.98 cm
Although this is the circumference of the entire circle... To solve for the circumference of a quarter-circle we must find the quarter of that:
43.98 * 1/4 = 10.99 cm
We are already provided with the other two sides, which are both equal to 7 cm since they are radii.
Perimeter = 10.99 +7 + 7 = 24.99 cm

Based on the table, which best predicts the end
behavior of the graph of f(x)?
Answer:
approaching negative infinity
Step-by-step explanation:
Since as x increases, the values of f(x) are approaching infinity, the function approaches negative infinity as the end behavior.
Answer:
Below.
Step-step-explanation:
As x increases from negative infinity f(x) decreases in value .
As x increases to positive infinity f(x) decreases in value.
For values of x on the negative side the graph rises to the left and on the positive x -axis it falls to the right.
