Answer:
[tex]A+B+C=130[/tex]
[tex]F+E+D=273[/tex]
Step-by-step explanation:
From the question we are told that:
Dimension of ABC
A=9
B=11
C=110
Dimension of FED
D=231
Generally the equation for the similar triangles is mathematically given by
[tex]\frac{A}{F}=\frac{B}{E}=\frac{C}{D}[/tex]
Therefore solving for F
[tex]\frac{9}{F}=\frac{110}{231}[/tex]
[tex]F=\frac{9*231}{110}[/tex]
[tex]F=18.9[/tex]
Therefore solving for E
[tex]\frac{11}{E}=\frac{110}{231}[/tex]
[tex]E=\frac{11*231}{110}[/tex]
[tex]E=23.1[/tex]

Zoe works in a bakery. She uses 250 milliliters of milk to make a loaf of bread. How many liters of milk will she need to make 15 loaves of bread?
Answer: 3.75 liters
Step-by-step explanation:
Zoe uses 250 milliliters of milk to make a loaf of bread.
If she needed to make 15 loaves therefore, she would do the following:
= 250 * 15 loaves
= 3,750 milliliters of milk
Then convert the above quantity to liters.
1 Liter = 1,000 milliliters.
3,750 milliters to liters is:
= 3,750 / 1,000
= 3.75 liters

how do I graph this linear equation?
4x+6y=-12
Answer: Simplifying
Step-by-step explanation:
Simplifying
4x + 6y = 12
Solving
4x + 6y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
4x + 6y + -6y = 12 + -6y
Combine like terms: 6y + -6y = 0
4x + 0 = 12 + -6y
4x = 12 + -6y
Divide each side by '4'.
x = 3 + -1.5y
Simplifying
x = 3 + -1.5y
Then you get your answer I think or hopeful get your answer. I hoped this helped!

Answer:
(x+3)²+(y+5)² = 36
Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius of the circle
Given
Centre (-3, -5)
a = -3 and b = -5
radius r = 6units
Substitute
(x-a)²+(y-b)² = r²
(x-(-3))²+(y-(-5))² = 6²
(x+3)²+(y+5)² = 36
hence the required equation is (x+3)²+(y+5)² = 36
The equation of a circle that represents a circle with a center at (-3, -5) and a radius of 6 unit is (x + 3)² + (y + 5)² = 36
Equation of a circleThe general equation of a circle is expressed as follows:
(x-a)²+(y-b)² = r²
where
r = radius of the circlea and b are the centre of the circleTherefore,
a = -3
b = -5
r = 6
Hence,
(x - (-3))² + (y - (-5))² = 6²
(x + 3)² + (y + 5)² = 36

Factorise fully:

12x² – x - 6
Answer:
y = (4x - 3)(3x + 2)
Step-by-step explanation:
Factorization is the process of taking like terms out of number such that one can rewrite an expression by its factors, or as the products of serval smaller expressions.
The first step to factoring an equation is to rewrite the linear term as the sum or difference of two other linear terms. One must do this in such as way that it shares a common factor with one of the other terms in the expression.
[tex]12x^2 -x - 6[/tex]

If the volume of the cylinder is 502.4 in?, what is the radius of
the base of the cylinder? Use 3.14 for i and enter your answer
as a whole number.
h=10 in
r= in.
Answer:
radius of the base of cylinder = 4 in
Step-by-step explanation:
Volume of cylinder = pi x r² × h
502.4 = 3.14 x r² x 10
502.4 = 31.4 x r²
r² = 502.4/31.4
r² = 16
r = 4 in
the scatterplot shows the number of hours that 12 people spent learning to type on a keyboard and each persons average typing speed. Based on the scatterplot, what is the best prediction of a persons average typing speed in words per min. if the person has spent 70 hours learning to type?
Answer:
85 wpm
Step-by-step explanation:
From the scatter plot, we can see the following;
At 20 hours, average typing speed = 34 wpm
At 30 hours, the average typing speed = 40 wpm
At 40 hours, the average typing speed = 51 wpm
At 50 hours, the average typing speed = 65 wpm
Average differences = ((40 - 34) + (51 - 40) + (65 - 51))/3 = 10.3
Approximating to a whole number = 10
Now, we can approximate that at 60 hours, average typing speed = 65 + 10 = 75 wpm
At 70 hours, the average typing speed = 75 + 10 = 85 wpm
Answer:
85 wpm

Step-by-step explanation:
To find the volume of a square pyramid, multiply the base by itself twice, then divide the height by 3. After getting both answers, multiply the answers.
In this case, the base is 18.
The height is 12.
First, we must multiply the base by itself twice.
18⋅18 = 324.
Next, divide the height by 3.
12/3 = 4.
Now that we have both answers, we multiply them.
324 ⋅ 4 = 1,296.
Therefore, 1,296 cm^3 is the volume of the square pyramid.

Solve the system by substitution.
x – 4y = -8
5у – 1 = x
Submit Answer
Answer:
y = -7 and x = -36
Step-by-step explanation:
x - 4y = -8
5y - 1 = x
→ Substitute 5y - 1 into x - 4y = -8
5y - 1 - 4y = -8
→ Simplify
y - 1 = -8
→ Add 1 to both sides
y = -7
→ Substitute y = -7 into 5y - 1
( 5 × -7 ) - 1 = -36
Answer:
The solution is (-36, -7)
Step-by-step explanation:
Since 5y - 1 = x, we can replace x in the first equation by 5y - 1:
5y - 1 - 4y = -8
Collecting like terms, we get:
y = -7
If y = 7, then by the second equation x = 5(-7) - 1 = -36
The solution is (-36, -7)

A group of students stood in a circle to play a game. The circle had a diameter of 22 meters. Which measurement is the closest to the circumference of the circle in meters?
Answer:
The closest measurement is 69 meters.
Step-by-step explanation:
We already know that 22 meters is the diameter and to find the circumference you need to multiply the diameter with π. We don't know π, so we are going with 3.14. When you multiply 22 and 3.14 together, you get 69.08 meters. You round the answer to the nearest meter, so it's 69 meters. So, the closest measurement is 69 meters.

Use the triangle shown to answer the questions that follow.
15 m
X
32
a) Using the 32° as the reference angle, label the hypotenuse (h), adjacent (a) and opposite (0).
b) Which trig function (cos, sin, or tan) could be used to solve for x?
c) Solve for x.
Answer/Step-by-step explanation:
a. Given that 32° is the reference angle, thus:
Hypotenuse is the side opposite to the right angle
Opposite side is opposite to the defence angle = x
Adjacent side is adjacent to defence angle = 15 m
b. Recall SOHCAHTOA.
We know the length of the adjacent side. We are asked to find x, which is the opposite side. So, we are dealing with Opposite side and Adjacent side.
The trigonometric function we will use to find x would be TOA:
That is,
Tan θ = Opp/Adj
c. Applying TOA:
Tan θ = Opp/Adj
θ = 32°
Opp = x
Adj = 15 m
Plug in the values
Tan 32 = x/15
15 × Tan 32 = x
9.37304028 = x
x = 9.4 (nearest tenth)
Helppp I really need this question answered
Answer:
32.5 units²
Step-by-step explanation:
We can find the area by dividing the figure into two shapes. If we solve for the area of a square and a triangle, we can add them together.
First, we can solve for the area of the 5x5 square. To find the area, we can multiply the two dimensions.
5 · 5 = 25 units²
Next, we can find the area of the triangle. It has an equal height to the square, so the height of the triangle is 5 units. The width isn't specified. Instead, we are shown that the width of both the square and the triangle equals 8 units. If we subtract the width of the square from the total, we can find the width of the triangle, too.
8 - 5 = 3
So, the height and the width of the triangle are 5x3. To find the area we can multiply these together, and then divide the product by two.
5 · 3 = 15
[tex]\frac{15}{2}[/tex] = 7.5
The area of the triangle is 7.5 units².
Finally, we can add the area of the triangle and the square together.
25 + 7.5 = 32.5
The area of the figure, then, is 32.5 units².
The answer is the last option.

HELP NOW!! 100 POINTS!!! What is the arc length the car traveled, to the nearest hundredth?
7.91 feet
8.32 feet
10.99 feet
11.89 feet
Answer:
10.99
Step-by-step explanation:
Took the test and it said it was this one :)
The arc length of the car traveled, to the nearest hundredth is 10.99feet
The formula for calculating the length of an arc is expressed as:
L = theta/360 × 2pi r
Given that
Radius r = d/2 = 30/2 =15ft
theta = 42 degrees
pi = 3.14
Substitute the given values into the formula as shown
L = 42/360×2(3.14)(15)
L = 42/360×94.2
L = 3956.4/360
L = 10.99feet
This shows that the arc length of the car traveled, to the nearest hundredth is 10.99feet
