Layla walked a total of 12 kilometers by making 4 trips to school. After 5 trips to school, how many kilometers will Layla have walked in total? Assume the relationship is directly proportional.
Answer:
[tex]=15km[/tex]
Explanation:
[tex]12[/tex] [tex]km[/tex] ÷ [tex]4[/tex]
[tex]=3[/tex] [tex]km[/tex] per trip to school
Now that we know that Layla walks 3 km to walk to school, we multiply that by 10
[tex]3[/tex] [tex]km[/tex] × [tex]5[/tex] [tex]trips[/tex]
[tex]=15[/tex] [tex]km[/tex]
∴ Layla walked 15 km in total

Find the area of the irregular figure.
4 in.
6 in.
A = [? ]in.²
10 in.
7 in.
11 in.
6 in.
Answer:
160 square inches
Step-by-step explanation:
You can split the irregular figure up into regular shapes:
the top 4x6 inch rectangle
the middle section can be a 18x6 rectangle (added 7+11 for the length)
the bottom 4x7 rectangle (sibtracted 10-6 for the width)
Then, find the area of each section with the equation A = lw.
A= 4(6) = 24 square inches
A = 18(6) = 108 square inches
A = 4(7) = 28 square inches
Add these areas up to get the total area of the irregular figure.
24 + 108 + 28 = 160 square inches
Can you guys help me find x and y
x -2y =-3
8x -6y =16
-2y -2y = 20
x - 7y = 14
Step-by-step explanation:
x - 2y = -3,____1 , 8x - 6y = 16____ 2
x - 2y = -3
x = 2y -3 ____ equation 3
eqn 3 in 2
2=> 8x - 6y = 16
8(2y-3) - 6y = 16
16y - 24 - 6y = 16
10y = 16 + 24
10y = 40
y = 40 / 10
y = 4
y=4 in eqn 3
3=> x = 2y - 3
x = 2(4) - 3
x = 8 - 3
x = 5
x = 5 , y = 4
-2y-2y = 20 , x - 7y = 14___ 1
-2y-2y = 20
-4y = 20
y = 20/ -4
y = -5
y = -5 in eqn 1
1=> x - 7y = 14
x - 7(-5) = 14
x - (-35) = 14
x + 35 = 14
x = 14 - 35
x = -21
x = -21 , y = -5

Divide 22 in half:
22/2 = 11
number of females = 11
Number of males = 11 + 13 = 24
Answer:
24 males, 11 females
Step-by-step explanation:

What is the length of BC if AC is x+9. And AB is 2x-8
Answer:
BC = 17 - x
Step-by-step explanation:
Let AC be the line segment and B be some point on it,
AB + BC = AC
( 2x - 8 ) + BC = x + 9 ...............(1)
BC = x + 9 - ( 2x - 8 )
BC = 17 - x

A soup can, shaped like a cylinder, has a diameter of 3.5 inches and a height of 5 inches. Each serving of soup is 15 cubic inches. If a can of soup this size costs $1.99, what is the cost for each serving of soup? Round to the nearest cent.
Answer: The answer to your question is Cost of a serving = $0.62
Step-by-step explanation:
Data
diameter = 3.5 in
height = 5 in
each serving = 15 in³
Cost of the can = $1.99
Process
1.- Calculate the volume of the can
Volume = πr²h
-Substitution
Volume = (3.14)(3.5/2)²(5)
-Simplification
Volume = (3.14)(3.062)(5)
-Result
Volume = 48.08 in³
2.- Use proportions and cross multiplication to find the cost of a serving.
48.08 in³ ---------------- $1.99
15 in³ ---------------- x
x = (15 x 1.99)/48.08
x = 29.85/48.08
x = $0.62
A mean weight of 2.2 pounds is computed for a random sample of 50 catfish from a lake....,,
What can you infer from this random sample?
A)You infer that the mean weight of all catfish is close to 2.2 pounds.
B)You infer that the mean weight of all catfish is exactly to 2.2 pounds.
C)You infer that the mean weight of catfish in the lake is close to 2.2 pounds.
D)You infer that the mean weight of catfish in the lake is exactly to 2.2 pounds.
Answer:
You infer that mean weight of catfusf in the lake is close to 2.2lbs
Step-by-step explanation:
Because it's a random sample of 50.
So plenty of catfishes left out of surveySo it lends to variation of mean .But mean remains closer to 2.2In what ways could creating similar shapes by using sequences of transformations be helpful in the real world? (e.g., a three-dimensional setting?)

George is solving the equation below by finding successive approximations. He started from a graph where he found the solution to be between 5 and 6. Using the lower and upper bounds from the graph, George did the following work for the first iteration. Step 1 Rewrite the equation so that it equals zero. Step 2 Evaluate the rewritten equation at the lower and upper bounds. Since the solution to the original equation is represented by a zero, one of the bounds should yield a negative difference and the other should yield a positive difference. Step 3 Take the average of the lower and upper bounds from the graph. Step 4 Evaluate the rewritten equation at . Step 5 Since this value of x yields a negative difference, use it to replace the previous upper bound that yielded a negative difference, . So, the bounds are now and . In what step, if any, did George make his first mistake? A. In step 1, George should have subtracted in the opposite order to set the equation equal to 0. B. In step 5, George should have used as the new lower bound. C. George made no mistakes, and his work is correct. D. In step 3, George should have averaged the two differences instead of the two bounds.
The mistake made by George is; D:George should have averaged the two differences instead of the two bounds.
How to Solve Successive Approximations?In Mathematics, successive approximation can be defined as a classical method that is used in Calculus for solving integral equations or initial value problems.
In this question, George started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that George made a mistake instep 5 because he should have used x = 3/2 as the new upper bound.

Describe the transformations from the parent function, and define the function of the following graph.
Answer: Vertical stretch by a factor of 5.8 , reflection across x-axis ⇒ answer B
Step-by-step explanation:
* Lets revise the vertical and horizontal stretch with reflection
- A vertical stretching is the stretching of the graph away from the
x-axis
- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched
by multiplying each of its y-coordinates by k.
- If k should be negative, the vertical stretch is followed by a reflection
across the x-axis
- A horizontal stretching is the stretching of the graph away from
the y-axis
- If 0 < k < 1 (a fraction), the graph of y = f(k•x) is f(x) horizontally
stretched by dividing each of its x-coordinates by k.
- If k should be negative, the horizontal stretch or shrink is followed
by a reflection in the y-axis
* Lets solve the problem
∵ G(x) = sin x
∵ F(x) = -5.8 sin x
∴ F(x) = -5.8 G(x)
- From the rule above
∴ G(x) is stretched vertically by scale factor -5.8
∵ The scale factor is negative
∴ The vertical stretch is followed by a reflection across the x-axis
* The transformation is:
Vertical stretch by a factor of 5.8 , reflection across x-axis
The bases of Triangle A and Triangle B are equal. The ratio of the height of
Triangle A to the height of Triangle B is 4 : 5. If the height of Triangle A is
16 cm and its base is 12 cm, what is the area of Triangle B?
Answer:
A = 120 cm²
Step-by-step explanation:
The 4 part of the ratio relates to the height of triangle A , then
16 ÷ 4 = 4 cm ← value of 1 part of the ratio, then
5 parts = 5 × 4 cm = 20 cm
The area (A) of triangle B is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 12 and h = 20 , then
A = [tex]\frac{1}{2}[/tex] × 12 × 20 = 6 × 20 = 120 cm²
