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
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
Express the following equation in the form of ax^2+bx+c=0.
(4a+3)^2 = (a+5)(a-2)
Answer:
15a² + 21a + 19 = 0
Step-by-step explanation:
(4a + 3)² = (a + 5)(a - 2)
16a² + 24a + 9 = a² + 3a - 10
15a² + 21a + 19 = 0

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)

Ray QS bisects PQR and mPQR =57°
Find mPQS
Answer:
The measure of angle ∠PQS is 28.5°
Step-by-step explanation:
If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half of the measure of this angle.
In our question
∵ Ray QS bisects ∠PQR
→ That means it divides it into two angles PQS and SQR
∴ m∠PQS = m∠SQR = [tex]\frac{1}{2}[/tex] m∠PQR
∵ m∠PQR = 57°
→ Multiply its measure by [tex]\frac{1}{2}[/tex] to find the measures its parts
∴ m∠PQS = [tex]\frac{1}{2}[/tex] × 57°
∴ m∠PQS = 28.5°
∴ The measure of angle ∠PQS = 28.5°
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

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.

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
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

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

[tex]A=98000\left(1+\frac{0.06}{4}\right)^{4\cdot 15}\implies A=98000(1.015)^{60}\implies A\approx 239435.54 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~ \stackrel{\textit{\Large Hector}}{\textit{Compound Interest Earned Amount}}[/tex]

well, seems that even though Hugo is charging some Johnny, the returned amount is more than with Hector, so Johnny should give Hugo a call.

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.
