Answer:
1 3/4
Step-by-step explanation:
We can set the length of the rectangle to l. We can make an equation with the area because we know length*width = area.
l*(4/5) = 7/5
4l = 7
l = 7/4 = 1 3/4
What is the slope line through 1,-1 and 6,2
Answer:
[tex]\huge\boxed{slope=\dfrac{3}{5}=0.6}[/tex]
Step-by-step explanation:
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (1, -1) and (6, 2).
Substitute:
[tex]m=\dfrac{2-(-1)}{6-1}=\dfrac{2+1}{5}=\dfrac{3}{5}=0.6[/tex]

D. d StartFraction StartRoot 3 EndRoot Over 2 EndFractionStep-by-step explanation:
What is the value of 1 − 2sin^2(105°)?
Given the expression
1 − 2sin²(105°)
= 1 - 2(sin105)²
= 1 - 2(0.9659)²
= 1 - 2(0.9330)
= 1 - 1.8660
= 0.8660
0.8660 can also be expressed as √3/2
Hence 1 − 2sin²(105°) is √3/2
Answer: D

Step-by-step explanation:
a motorboat moves across a lake at a constant speed. when it begins it from the shore. after 9 minitues it is 14 km from the shore. which function decribes the motorboat distance from the shore?
a. y= 4x + 50
b. y= -4x + 50
c. y= 9x + 50
d. y= -9x + 50
Answer:
Answer:
The function describes the motorboat's distance from the shore
Step-by-step explanation:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, rate of change =
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+c
Where m is the slope and c is the constant
Substitute the values in the equation :
y=-4x+50
Where y is the final distance and x is the minutes
So, Option C is true
Hence The function describes the motorboat's distance from the shore

Joe is 3 years less than twice as old as Sara. The sum of the ages of Joe and Sara is 42. If x represents Sara's age,
Answer:
Sara or x=15, Joe=27
Step-by-step explanation:
Using J to represent Joe and S to represent Sara
J=2S-3
J+S=42 or J=42-S
Substitute for J:
42-S=2S-3
3S=45
S=15
J=2(15)-3 = 27

Answer:
1) C=80°
2) A=C= 54°
Step-by-step explanation:
1) 180-60-40=80
2)180-72=108
108/2=54
Hope this helps! :)
Answer:
1. 80º
2. Both are 54º
Step-by-step explanation:
1. If you add 60º + 40º in problem 1, you get 100º. We need to get it to equal 180º, so this means the missing angle would be 80º
2. Just like in the first one, we need this to equal 180º. So, let's go backwards.
180 - 72 = 108
Now, since the remaining angles are equal, let's divide 108º by 2
108 / 2 = 54º
Hope this helps :)

Nina Milling assembles transistor radios. she is paid $0.54 for each radio assembled during a regular work week, $0.62 for each radio assembled on on sundays. What is Nina's total pay for a week in which she assembled the following number of radios?
Answer:
I would need to know the number of radios she made each day.
Step-by-step explanation:
lets say she assembled 2 radios a day, which means we would do 0.54 x 2 (that would be 1.08) and then times it by 6 ***not incuding sunday***
you would get $6.48
then for sunday we would do 0.62 x 2 (that would be 1.24) .
now we add 6.48 and 1.24 to get $7.72 a week.

Han has Spent 75 minutes practicing the piano over the weekend priya practice the violin for 152% as much time as hand practicing piano how long does she practice
Answer: 114 minutes
Step-by-step explanation:
From the question, we are informed that Han has Spent 75 minutes practicing the piano over the weekend while Priya practice the violin for 152% as much time as Han used in practicing the piano.
Therefore, the number of minutes used in practicing by Priya would be gotten by multiplying 152% by 75 minutes. This would be:
= 152% × 75 minutes.
= 152/100 × 75minutes
= 1.52 × 75 minutes
= 114 minutes

Step-by-step explanation:
Solve for v.
19v – 18 = 16 + 17v
Answer:
v= 17
Step-by-step explanation:
Start with the given equation.
19v – 18 = 16 + 17v
Move -18 to the other side, and swap it's sign.
19v = 16 + 18 + 17v
Move 17v to the other side and swap it's sign.
19v - 17v = 16 + 18
Combine like terms.
2v = 34
Divide by 2v.
v = 17
Answer:
v = 17
Step-by-step explanation:
Given
19v - 18 = 16 + 17v ( subtract 17v from both sides )
2v - 18 = 16 ( add 18 to both sides )
2v = 34 ( divide both sides by 2 )
v = 17
16. Find the length of the median CD.
17. Find the coordinates of E, the midpoint of BC
18. Find the length of the median AE.
Step-by-step explanation:
16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)
C (2,-3) D (6,3)
CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)
CD = sqaureroot of ( 16 + 36)
CD = sqaureroot of 52 = 2 root 13 = length
17. E (5, - 1) because the point is under the x axis.
Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)
B (8,1) C (2, - 3)
Midpoint of BC = ((2+8)/2 , (-3+1)/2)
= (10/2 , - 2/2)
= (5, - 1)
18. Length of AE
A (4,5) E(5,-1)
Square root of ((5-4)^2 + (-1-5)^2)
Square root of (1^2 + - 6^2)
Square root of ( 1 + 36)
Square root of 37 = root 37

You are printing out information packets for your company. You will need a total of 6,400 pages to complete all of the packets. How many reams of 500 pages each will you need in order to print out all of these packets?
Answer:
13 reamsStep-by-step explanation
Given
Total number of pages to complete the packet = 6400 pages
If each ream contains 500pages, then:
Total number of reams needed = Total pages/number of pages per ream
Total number of reams needed = 6400/500
Total number of reams needed = 12.8
Hence you will need about 13 reams for all the packets

The sum of two numbers is 4. The larger number is 12 more than three times the smaller number. What are the numbers?
Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!
the difference of 2 numbers x and y multiplied by 6

I don’t get 9.) so if anyone can’t skip it I need help with 10.) too
Answer:
ok number 9.) i believe its 7 if im wrong im so sorry
Step-by-step explanation:
Answer:
I will help with 10 i don't get 9 sorry so the answer is (a) F(5,4)
Step-by-step explanation:
So you have the midpoint and you put f(x, y) and D(-3,-8)
So
E=(x-3/2, y-8/2) =(1,-2) so
X-3/2 =1 , x-3=2 so x = 5
And y-8/2 = - 2. , so y-8 = - 4. , so y =4
So F =(5, 4)

Jervane is planning on buying a coffee and several donuts for a road trip. She wants to spend no more than $20 in total. Coffee costs $3 and donuts are $2 each. Write and solve an inequality to determine the maximum number of donuts that Jervane can buy. Be sure to include units on your answer.
Answer:
8
Step-by-step explanation:
Given:
Total money Jervane can spend = $20.
Cost of a coffee = $3.
Cost of a donut = $2.
To find: Maximum number of donuts Jervane can buy.
Solution:
Let the number of donuts she can buy be [tex]x[/tex].
She wants to spend no more than $20 in total.
So,
[tex]3+2x\leq 20[/tex]
[tex]\Rightarrow 2x\leqslant 20-3[/tex]
[tex]\Rightarrow 2x\leqslant 17[/tex]
[tex]\Rightarrow x\leqslant \frac{17}{2}[/tex]
[tex]\Rightarrow x\leqslant 8 \frac{1}{2}[/tex]
As the number of donuts can only be a natural number.
Hence, the maximum number of donuts that Jervane can buy are 8.
