14y-8=13
We add 8 on both sides to cancel it out and add it to 13.
14y-8=13
+8 +8
14y=21
Now we divide 14 on both sides to cancel it out, separate it from the y, and to divide it from 21.
14y=21
/14 /14
y=1.5
---
hope it helps
Answer:
Add 8 to both sides of the equation to get 14y=21
Divide both sides of the equation by 14 to get y= 1.5

i need the help alot
Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}
Cone a and cone b both have a height of 5 in. The volume of cone a is 20.9cubic in, the volume of cone b is 4 times the volume of cone a, about how many times longwr is the diameter of cone b than the diameter of cone a?
Answer: two times
Step-by-step explanation:
Given
height of cone A and B [tex]h_a=h_b=5\ in.[/tex]
The volume of cone A [tex]V_a=20.9\ in.^3[/tex]
The volume of cone B is 4 times of cone A
the volume of a cone is [tex]\frac{1}{3}\pi r^2h[/tex]
The volume of cone A
[tex]V_a=\dfrac{1}{3}\pi r_a^2h_a=20.9\quad \ldots(i)[/tex]
The volume of cone B
[tex]V_b=\dfrac{1}{3}\pi r_b^2h_b=4\times 20.9\quad \ldots(ii)[/tex]
divide (i) and (ii) we get
[tex]\Rightarrow \dfrac{r_a^2}{r_b^2}=\dfrac{1}{4}\\\Rightarrow \dfrac{r_a}{r_b}=\sqrt{\dfrac{1}{4}}=\dfrac{1}{2}\\\Rightarrow \dfrac{d_a}{d_b}=\dfrac{1}{2}\\\Rightarrow d_b=2d_a[/tex]
thus, diameter of cone B is twice the diameter of A

AA, SSS, SAS, or not similar??
Answer:
C
Step-by-step explanation:
This is showing Side Angle Side congruency because first of all where the triangles connect shows vertical angles meaning that they are congruent
Second of all the triangle are similar because or proportions
[tex]\frac{9}{6} =1..5\\\frac{6}{4} =1.5[/tex]
they are both showing proportions of 1.5 therefore the sides are similar
A parallelogram with an area of 60 square units is formed by four lines in a coordinate plane. The parallelogram has one vertex in each quadrant. Three of the lines are shown below. Graph the fourth line.
Answer:
The answer above is wrong, the line is actually supposed to be one to the left, so it would be going through (7,4) and (2,-2)

Answer:
71.13
Step-by-step explanation:
The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9
The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2
The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13
Which equation can be used to find the area of the composite figure pictured below?
7 m
8 m
15 m
: A = 24 (8) + (15 x 7)
= A= 8 (15) + (15 x 7) + }(9 x 8) = A= 8 (15) + 15 (7) +9 (8)
: A = 15 (15) + (9 x 8)
Answer:
A.
Step-by-step explanation:
The figure is made up of a rectangle and two triangles.
The dimensions of the 3 polygons are:
Rectangle: 8 m by 15 m
Triangle 1: 15 m base and 7 m height
Triangle 2: 9 m base and 8 m height
Total area =
= [8(15) + 15(7)/2 + 9(8)/2] m^2
Answer: A.
Functions A function is defined by the equation f(x) = 2x - 5
How much will 5 ounces cost?

How much will 5 ounces of yogurt cost?
Answer:
ok.
Step-by-step explanation:
Answer:
$8
Step-by-step explanation:

1 ounce = 0.8 × 2 = $1.60
5 ounces $1.60 × 5 = $8
Expand the following. In other words, remove the parentheses (brackets):
-5(2x - 4y)
B -10x + 20y
A 10xy
C -10x - 20y
D 10x - 20y
Answer:
B
Step-by-step explanation:
-5(2x-4y)
-5*2x = -10y
-5*-4y = 20y
So, -10x+20y

What is the approximate difference in the circumference of a circle with a radius of 4 ft and the circumference of a circle with a radius of 6 ft?
Answer: 12.57 ft
Step-by-step explanation:
Circumference of circle with radius of 4ft.
= π * radius * 2
= 22/7 * 4 * 2
= 25.14 ft
Circumference of circle with radius of 6ft.
= 22/7 * 6 * 2
= 37.71 ft
Difference = 37.71 - 25.14
= 12.57 ft

Answer:
10^-9
Step-by-step explanation:
Use the table below to determine the approximate height of the flag pole.
Answer:
B 17.5 ft
Step-by-step explanation:
tangent = opposite / adjacent
tan 35° = h / 25
multiply both sides by 25
h = 25 (tan 35°)
tan 35° = 0.70 (from your calculator)
h = 25 (0.70)
h = 17.51 ft.
