Awnsers
14 ₂

14 ₁₀
Answer:
14^2
Step-by-step explanation:
i just plugged into calculator lol
Given expression:
14⁶ / 14⁴
Using the exponent rule;
[tex]\frac{x^{n} }{x^{m} }[/tex] = [tex]x^{n-m}[/tex]
So;
x = 14
n = ⁶6
m = 4
So;
[tex]\frac{14^{6} }{14^{4} }[/tex] = 14⁶⁻⁴
= 14²

Anita needs to build a house for a school project. The base of the house is a rectangle where the length of a rectangle is 8 more than the width. Its area is 240 ft sq
L = lengh
W = width
french reasoning ( hello from France ) !
The base of the house is a rectangle where the length of a rectangle is 8 more than the width.
=> L = W + 8
and
Its area is 240 ft sq
W x L = 240
L = W + 8
W x L = 240
=> W x (W+8) = 240
W² + 8W - 240 = 0
Δ = 8² - 4*1*(-240) = 32²
W' = (-8 + 32) / 2 = 12 ft
W'' = (-8 - 32) / 2 = impossible
at the end
W the width = 12 ft
and then the lengh = 12 + 8 = 20
area = 12 x 20 = 240 ft²

Which best describes the graph of the cubic function f(x) = x3 x2 x 1?.
Graph of a function is plotting of its input and corresponding output. The graph of the considered cubic function is attached below.
How do we make graph of a function?Suppose the considered function whose graph is to be made is [tex]f(x)[/tex]
The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values [tex]f(x)[/tex]
are plotted on the vertical axis.
They are together plotted on the point
[tex](x,y) = (x, f(x))[/tex]
This is why we usually write the functions as:
[tex]y = f(x)[/tex]
For the considered function [tex]f(x) = x^3 +x^2 +x + 1[/tex] is attached below.

A truck driver averages 45 miles per hour while delivering freight and 60 miles per hour on the return
trip. The total drive time is 7 hours. How long does each trip take?
pls send help a girl is struggling
Answer:
Delivery Trip: 3 hours
Return Trip: 4 hours
Step-by-step explanation:
d/60 + d/45 = 7
45d/2700 + 60d/2700 = 7
105d/2700 = 7
105d = 18900
d = 180
180/60 = 3
180/45 = 4
Answer:
delivering 180/45 = 4 hours and return trip 180/60 = 3 hours
Step-by-step explanation:
d = unknown number to calculate each trip
[tex]\frac{d}{45}[/tex] + [tex]\frac{d}{60}[/tex] = 7
find common denominator (45 * 60 = 2700)
([tex]\frac{60}{60}[/tex])*([tex]\frac{d}{45}[/tex]) +( [tex]\frac{45}{45}[/tex])*([tex]\frac{d}{60}[/tex]) =7
[tex]\frac{60d}{2700}[/tex] + [tex]\frac{45d}{2700}[/tex] =7
[tex]\frac{60d + 45d}{2700}[/tex] =7
[tex]\frac{105d}{2700}[/tex] = 7
105d = 7 * 2700
105d = 18,900
d = 18900/105
d = 180
delivering 180/45 = 4 hours
return trip 180/60 = 3 hours

A farmer had 3,000 acres of land. He planted 30% of it with wheat, 45% of it with corn, and the rest with oats.
Find how many acres he planted with each kind of grain
Answer:
900 acres of wheat
1350 acres of corn
750 acres of oats
Step-by-step explanation:
3000 = 100%
÷ 10 both sides
300 = 10%
× 3
900 = 30%
300 = 10%
× 4
1200 = 40%
300 ÷ 2 = 150 (5%)
1200 + 150 = 1350
1350 + 900 = 2250
3000 - 2250 = 750

If the slope of a line is 7/10, how much vertical change will be present for a
horizontal change of 63 ft?
If the slope of the line is 7 /10, the vertical change that will be present for a horizontal change of 63 ft is 44.1 ft
What is a slope?The slope of a line is the measure of its steepness. Therefore,
slope = change in y(vertical) / change in x(horizontal)
slope = y₂ - y₁ / x₂ - x₁
slope = 7 / 10
Therefore,
7 / 10 = y / 63
cross multiply
441 = 10y
divide both sides by 10
y = 441 / 10
y = 44.1 ft

Ayden collects football, baseball, and Pokémon cards. He has four times as many baseball cards as football cards. His Pokémon cards contain 7 more cards than his baseball collection. If he has 106 cards all together, how many of each type does he have?
Answer: Ayden has 11 football cards,44 baseball cards and 51 Pokemon cards which totals 106 cards all together
Step-by-step explanation:
STEP 1 :
Let x represent number of football cards
He has four times as many baseball cards as football cards, let baseball cards be = 4x
Pokémon cards contain 7 more cards than his baseball collection,let Poke mon cards = 4x +7
Step 2 :
Putting in equation we have that
Football cards + Baseball cards + Pokemon cards = 106 cards
Therefore,
x + 4x + 4x+7 = 106
9x + 7 = 106
9x = 106-7
9x = 99
x =99/9 = 11
therefore football cards , x = 11 football cards
baseball cards = 4x = 4 x 11 = 44 baseball cards
Pokemon cards = 4x+7= 4x11 +7 = 44 +7 =51 Pokemon cards

5x-3+3x+7 if x=3
Answer:
28
Step-by-step explanation:
Replace x with 3, and multiply the number next to it.
5(3)= 15
3(3)=9
so, 15-3+9+7=28
Answer:
28
Step-by-step explanation:
To solve this, replace every x with (3). If x is next to a number, that means you multiply that number and the value of x. This gives us the equation 5(3)-3+3(3)+7. When a set of parentheses are next to a number, you multiply. 5 times three is 15, and 3 times 3 is 9. This gives us 15-3+9+7. 15 - 3 is 12. 12 + 9 is 21. 21 + 7 is 28. 28 is your answer.

The time it takes to complete a certain job is directly proportional to the number of units produced. If it takes 22 minutes to proficiently 18 units, how many units are produced in 33 minutes?
Answer:
27 units
Step-by-step explanation:
let t represent time and n represent number of units
given t is directly proportional to n then the equation relating them is
t = kn ← k is the constant of proportion
to find k use the condition t = 22, n = 18 , then
22 = 18k ( divide both sides by 18 )
[tex]\frac{22}{18}[/tex] = [tex]\frac{11}{9}[/tex] = k
t = [tex]\frac{11}{9}[/tex] n ← equation of variation
when t = 33 , then
33 = [tex]\frac{11}{9}[/tex] n ( multiply both sides by 9 )
297 = 11n ( divide both sides by 11 )
27 = n
27 units are produced in 33 minutes
Give the coordinates of each vertex (D, E and F) and explain how you found the coordinates using the transformation rules.
Step-by-step explanation:
We have that the vertices of triangle ABC are:
A(4, 2)
B(7, 9)
C(7, 2)
First, we are reflecting over the y axis, which makes (x,y) map onto (-x, y). This gives us:
A'(-4, 2)
B'(-7, 9)
C'(-7, 2)
Then, we translate 5 units down, meaning we subtract 5 from each of the y coordinates. This gives us a final answer of:
D(-4, -3)
E(-7, 4)
F(-7, -3)
