6(6+y)
Answer:
36+6y
Step-by-step explanation:
you have to multiply 6 on 6+y because distributive property basically means to share out so you do 6(6)+(6)y
6(6) equals 36 (6x6) and 6(y) is just 6y
36+6y

∠D = 68°
Step-by-step explanation:
In a quadrilateral that is inscribed in a circle, opposite angles are supplementary.
∠D = 180° - ∠B
∠D = 180° -112°
∠D = 68°
Triangle CDE is dilated by a scale factor of 1/ 3 to form triangle C'D'E'. Side CD measures 42. What is the measure of side C'D'? ASAP!!!
Answer:14
Step-by-step explanation:
The measure of C'D' is 14.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object,
We have,
Triangle CDE is dilated by a scale factor of 1/3 to form triangle C'D'E'.
This means,
CD = 42
C'D' = 1/3 x 42 = 14
Thus,
C'D' is 14.

3. The trapezoid below contains a square and two right triangles. Find the perimeter of the trapezoid.
Answer:
Perimeter of trapezoid = 25.66 cm
Step-by-step explanation:
Trapezoid ABCD contains two triangles ΔABF, ΔCDE and a square with side length 4 cm.
By applying Pythagoras theorem in ΔABF,
AB² = BF² + AF²
AB² = 4² + 3²
AB = [tex]\sqrt{16+9}[/tex]
AB = 5 cm
Similarly, By applying Pythagoras theorem in ΔCDE,
CD² = DE² + CE²
CD² = 4² + 4²
CD = [tex]\sqrt{32}[/tex]
CD =5.66 cm
Perimeter of the given trapezoid = AB + BC + CD + AD
= 5 + 4 + 5.66 + (3 + 4 + 4)
= 25.66 cm

Every week for 40 weeks, Abeke earned $76 selling ice cream and 35$ delivering newspapers. Write a numerical expression to show how much money Abeke earned in 40 weeks.
Answer: 40 x (76+35)
Step-by-step explanation:
Given: Every week Abeke earned,
$76 by selling ice cream
$35 by delivering newspapers.
i.e. Total amount earned in 1 week = $ (76+35)
Now Total amount earned in 40 weeks = 40 x (76+35)
The numerical expression to show how much money( in dollars) Abeke earned in 40 weeks = 40 x (76+35)
We have to simplify it to get the total money earned in 40 weeks i..e. $4440.

A population of rabbits doubles every 4 months. If the population starts out with 8 rabbits how many will there be in 1 year
Given:
The initial population of rabbit = 8
Population of rabbits doubles every 4 months.
To find:
The number of population in 1 year.
Solution:
The exponential growth model is
[tex]y=a(b)^x[/tex] ...(i)
Where, a is the initial population, b is growth factor, x is time period.
We know that,
12 month = 1 year
So, there are 3 time period of 4 months in an year.
Initial population of rabbit (a) = 8
Population of rabbits doubles every 4 months. So, growth factor is 2, i.e., b=2 and the time period is 3, i.e., x=3.
Putting a=8, b=2, x=3 in (i), we get
[tex]y=8(2)^3[/tex]
[tex]y=8(8)[/tex]
[tex]y=64[/tex]
Therefore, the population of rabbit in 1 year will be 64.

11
y
-3
-2
-1
0
Answer:
Step-by-step explanation:
The slope of the line y = (x/4) - 23/4 is 1/4.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
The points,
x → y
-4 → -3
1 → -2
6 → -1
11 → 0
From the table, we interpreted 2 points (-4, -3) and (11, 0)
If a line passes through two points (x₁ ,y₁) and (x₂, y₂),
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (0+3) / (11+4)
m = 1/5
So, the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) (x - x₁)
y - y₁ =m (x - x₁)
y +3 = (1/4) (x -11)
y = (x / 4) - 11/4 -3
y = (x/4) - 23/4
Therefore, the slope of the line is m = 1/5.
