36 = 5x
5x = 36
DIVIDE 5 to BOTH SIDES
5x/5 = 36/5
SIMPLIFY IT!
x = 36/5

Problem 2
Kayla has a goal to hike at least 75 miles. She has
already hiked 20 miles.
She plans to hike n miles each week for the next 6
weeks.
Which inequality describes the nuinber of miles Kayla
should hike each week to meet her goal?
20 + 6n < 75
20 - 6n < 75
20 + 6n > 75
20 - 6n > 75
( the signs are supposed to have the line underneath it )
Answers
Answer:
20 + 6n > 75(the sign has an underline)
To determine how many miles Kayla needs to hike each week for the next 6 weeks to reach her goal of at least 75 miles, we can subtract the miles she has already hiked from her target goal and divide it by the number of weeks remaining.
Target goal - Miles already hiked = Miles remaining
75 miles - 20 miles = 55 miles remaining
Now, we divide the remaining miles by the number of weeks:
55 miles / 6 weeks = 9.17 miles per week (approximately)
Therefore, Kayla needs to hike approximately 9.17 miles each week for the next 6 weeks in order to reach her goal of at least 75 miles.

Vol_prism = 48 (all answers should have the units cm^3)
Vol_pyramid = 25
Vol_cyl = 37.68
Vol_cone = 12.56
Vol_sphere = 113.04
Step-by-step explanation:
This was a very compact problem (5 problems!) You read the chart top to bottom and each column is a different problem.
Vol of a prism:
V = l×w×h = 4×4×3
= 48 cm^3
Vol of a pyramid:
V = 1/3Base•h
= 1/3 (5×5)•3
= 25 cm^3
Vol of a cylinder:
V = pi•r^2•h
= pi•2^2•3
= pi•4•3
= 12pi = 12(3.14)
= 37.68 cm^3
Vol of cone:
= 1/3pi•r^2•h
= 1/3pi•2^2•3
= 4pi = 4(3.14)
= 12.56 cm^3
Vol of a sphere:
V = 4/3pi•r^3
= 4/3 pi•3^3
= 4/3 pi•27
= 36pi = 36(3.14)
= 113.04 cm^3
Pheewwwww! That was a lot! Hopefully you are just reviewing all your volume formulas. Hope this helps!

The Apple iPad Mini 2 has dimensions of: Height: 7.9 in, Width: 5.30 in, Depth: 0.30 in.
1. What is the volume of the Apple iPad Mini 2?
2. If Pear-Apple applies a scale factor of 1.25 to the iPad Mini 2 to make a new tablet, what would be the new volume in cubic inches?
3. Suppose Pear-Apple applies a scale factor of .75 to the iPad Mini 2 to make the Lil Mini. What would be the volume for the Lil Mini in cubic inches.
4. Pear-Apple scraps their plans and decide to come up with a product that is half the volume of the iPad Mini. What scale factor should they use and what should the dimensions be?
5. Pear-Apple also wants to make a bigger tablet. They want the tablet to have twice the volume from the iPad Mini 2. What’s the scale factor and dimensions of the tablet?
Answers
The volume of the Apple iPad Mini 2 is 12.561 in³.
The new volume of the Pear-Apple is 24.53 in³.
The new volume of the Pear-Apple is 5.3in³.
The scale factor to have a volume that is half that of the iPad Mini is 0.79.
The scale factor to have a volume that is double that of the iPad Mini is 1.26
What is the volume of the Apple iPad Mini 2?Volume = length x width x height
7.9 x 5.30 x 0.30 = 12.561 in³
What is the volume after the scale factors are applied?Dimensions after the 1.25 scale factor is applied: (1.25 x 7.9) x (1.25 x 5.30) x (1.25 x 0.3)
= 9.875 x 6.625 x0.375 = 24.53 in³
Dimensions after the 0.75 scale factor is applied: (0.75 x 7.9) x (0.75 x 5.30) x (0.75 x 0.3)
= 5.925 x 3.975 x 0.225 = 5.3in³
Scale factor to have a volume that is double that of the iPad Mini : [tex]2^{1/3}[/tex] = 1.26
Scale factor to have a volume that is half that of the iPad Mini : [tex]0.5^{1/3}[/tex] = 0.79

The radius of Convergence for the function [tex]\frac{\[(-1)^{n} \; x^{n} }{\sqrt[3]{n} }[/tex] is 1.
What is radius of convergence?The radius of the largest disk at the center of the series in which the series converges.
Perform the ratio test for absolute convergence, which says
if [tex]\lim_{n \to \infty} \frac{a_{n}}{a_{n+1}}[/tex] =L
Then,
1) if L<1, the series is absolutely convergent
2) If L>1, the series is divergent
3) If L= 1, apply a different test.
Now, Applying test
[tex]a_{n+1}[/tex] =[tex]\frac{(-1)^{{n+1} } \; x^{n+1}}{\sqrt[3]{n+1} }[/tex]
So,
[tex]\lim_{n \to \infty} \frac{a_{n+1}}{a_{n}}[/tex] = [tex]\lim_{n \to \infty}|\frac{ (-1)^{{n+1} } \; x^{n+1}/\sqrt[3]{n+1} }{ (-1)^{n} \; x^{n} /\sqrt[3]{n} } |[/tex]
= [tex]\lim_{n \to \infty}|\frac{ (-1)^{{n+1} } \; x^{n+1}\sqrt[3]{n}}{ (-1)^{n} \; x^{n} \sqrt[3]{n+1} } |[/tex]
= [tex]\lim_{n \to \infty}|\frac{ (-1) \; x^{n}\sqrt[3]{n}}{ \sqrt[3]{n+1} } |[/tex]
= [tex]\lim_{n \to \infty}\sqrt[3]{\frac{1}{1+\frac{1}{n}} } } |x|[/tex]
Applying the limit n→∞,
= 1 x |x|
= |x|
By ratio test, the given series will be convergent if |x|< 1.
So, the radius of Convergence = 1

Answer:
A=72CM^2
Step-by-step explanation:
The answer is 72cm^2 because the area of a triangle is h x b divided by two because the triangle is half of a square, since the square is side times side, the answer is 12x12 divided by two, wich is 144/2. The final answer is 72
Answer:
72
Step-by-step explanation:
area of a triangle = 1/2 × base length × height
base length = 12 and height = 12
so area = 1/2 × 12 × 12
==> multiply 12 by 12
area = 1/2 × 144
==> divide 144 by 2
area = 72

A triangle has an area of 14 square units. Its height is 7 units. What is the length of its base
Answers
Answer:
4 units
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
given A = 14 and h = 7 , then
[tex]\frac{1}{2}[/tex] × 7b = 14 ( multiply both sides by 2 to clear the fraction )
7b = 28 ( divide both sides by 7 )
b = 4 units
Step-by-Step Explanation:
Let ‘x’ be the Base of the Triangle.
Area = 14 square units
Height = 7 units
Therefore,
= Area = 1/2 * Base * Height
= 1/2 * x * 7 = 14
= x/2 * 7 = 14
= 7x/2 = 14
= 7x = 14 * 2 = 28
=> x = 28/7 = 4
Therefore, Base = x = 4 units

Solve by using substitution. Express your answer as an ordered pair. 2x+y=-5 y=x+4
Answers
Step-by-Step Explanation:
=> 2x + y = -5 (Eq. 1)
=> y = x + 4 (Eq. 2)
Substitute value of ‘y’ from Eq. 2 in 1 :-
2x + y = -5
2x + (x + 4) = -5
2x + x + 4 = -5
3x + 4 = -5
3x = -5 - 4
3x = -9
x = -9/3
=> x = -3
Therefore, x = -3
Substitute value of ‘x’ in Eq. 2 :-
y = x + 4
y = (-3) + 4
=> y = 1
Therefore, y = 1
This Solution can be written in the ordered form as (-3, 1)

What is the value of x?
Answers
Step-by-step explanation:
2 things to remember :
1. the sum of all angles in a triangle is always 180°.
2. the sum of all angles around a single point on one side of a line is also 180° (because the line can be seen as the diameter of a circle, the point as its center, and so every side of the line is a half-circle = 180°).
so, the third, unnamed angle in the triangle is the supplementary angle to 142° (that means they complete each other to full 180°).
it is therefore
180 - 142 = 38°
and then, inside the triangle
180 = 66 + x + 38 = 104 + x
x = 76°
