amanda has a board that is 7 feet long. how many 1/4 foot sections can she cut from this board
Answer:
28
Step-by-step explanation: You need to divide 7 by 1/4. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 7 times 4/1. Which is 28/1 which is 28.

Determine whether the system of linear equations has one solution infinitely many solutions or no solution explain your reasoning. y=3x+5 and y=3x-5
Answer: The equations have no solution because no solution graphs have the same slopes but difference y- intercepts.And by looking at the equations they both have same slope as 3 but different y-intercepts 5 and -5.
Step-by-step explanation:
y= 3x + 5
y = 3x- 5
3x + 5 = 3x -5
-3x -3x
5 ≠ 5

sheena is shocking a shelf with bags of flour that weigh 5 1/4 pounds each if sheena stocks the shelf with 13 bags of flour find the combined weight of 13 bags
Answer:
[tex]68\frac{1}{4}[/tex] pounds
Step-by-step explanation:
The combined weight of 13 bags is 13 multiplied by the weight of each bag.
The weight of each bag is [tex]5\frac{1}{4}[/tex] pounds. Therefore, the weight of 13 bags is:
[tex]5\frac{1}{4} * 13\\ \\= \frac{21}{4} * 13\\[/tex]
[tex]= 68\frac{1}{4}[/tex] pounds

Round your final answer to the nearest hundredth of a second.
Answer:
0.20secondStep-by-step explanation:
Given the distance of a swinging pendulum modeled by the equation P(t)=−5cos(2πt)+5, to get the first time the pendulum reaches 3.5cm, we will have to substitute P(t)= 3.5cm into the given equation and calculate the value of 't' as shown;
3.5 = −5cos(2πt)+5
Subtracting 5 from both sides;
3.5-5 = −5cos(2πt)+5-5
-1.5 = −5cos(2πt)
Dividing both sides by -5 will give;
[tex]\frac{-1.5}{-5} = cos2\pi t\\0.3 = cos2\pi t\\2\pi t=cos^{-1} 0.3\\2\pi t = 72.54^{0} \\360t = 72.54^{0} \\t = \frac{72.54}{360} \\t = 0.20secs[/tex]
The first time the pendulum reaches 3.5cm is after 0.20secs

The student council at Clarksville High School is making T-shirts to sell for a fundraiser, at a price of $10 apiece. The costs, meanwhile, are $8 per shirt, plus a setup fee of $98. Selling a certain number of shirts will allow the student council to cover their costs. What will the costs be? How many shirts must be sold?
Answer:
Costs are $490
49 shirts are sold
Step-by-step explanation:
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
49 shirts sold
If f(x)= 3x^2-2x+4.and g(x)= 5x^2 +6x -8find(f-g)(x)
Answer:
-2x^2-8x+12
Step-by-step explanation:
f(x)= 3x^2-2x+4
g(x)= 5x^2 +6x -8
(f-g)(x) = 3x^2-2x+4-(5x^2 +6x -8)
Distribute the minus sign
(f-g)(x) = 3x^2-2x+4-5x^2 -6x +8
Combine like terms
-2x^2-8x+12

What is the solution to the equation -4(2x+3) =2x+6-(8x+2)?
x = -10
x = -8
X=-5/2
x=-4/7
Answer:
x = -8
Step-by-step explanation:
solve:
-4(2x+3) =2x+6-(8x+2)
-8x-12 = 2x+6-8x-2
-8x-12 = -6x + 4
-2x = 16
x = -8
Hope this helps.
Good Luck
Answer:
[tex]x = - 8[/tex]
Second answer is correct
Step-by-step explanation:
[tex] - 4(2x + 3) = 2x + 6 - (8x + 2) \\ - 8x - 12 = 2x + 6 - 8x - 2 \\ - 8x - 12 = - 6x + 4 \\ - 8x + 6x = 12 + 4 \\ - 2x = 16 \\ \frac{ - 2x}{ - 2} = \frac{16}{ - 2} \\ x = - 8[/tex]
hope this helps

Ok so I’m in high school and I forgot everything I learned in 6-7th grade so what is 14/2 + 12/6 I got 54/6 but I don’t know what to do to get it into simplest form btw I’m very dumb so please explain it like you would to a 4yr old
Answer:9
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. (14/2 x 3/3)+(12/6 x 1/1). Complete the multiplication and the equation becomes 42/6+12/6. The two fractions now have like denominators so you can add the numerators. 42+12/6=54/6. Divide 54 by 6 and get 9. hope this helps :)
If functions f and g are inverses of each other, then what is their composition, f(g(x))? (only have 2 hours to answer!) a. f(x) b. 0 c. 1 d. x

Solve the system by substitution.
y = 5x
y = -3x + 24
pls help :(
Answer:
x=3, y=15
Step-by-step explanation:
We substitute 5x for y, getting 5x = -3x + 24. We add 3 x to both sides, and have a equation like this: 8x = 24. Divide by 8 on both sides, and we know that x = 3. Since y is 5x, y is 5*3, which is 15.
please help quickly !
Answer:
16.5x = 465.3

Suppose a family pays $29.99 for dinner . They leave a 15% tip. Find both the tip and the total price of the meal. Round your answers to the nearest cent.
Show your work below:
Tip = $15.20
Total = $45.20
Tip = $9.40
Total = $24.56
Tip = $1.10
Total = $31.10
Tip = $4.50
Total = $34.50
Answer:
Tip = $4.50
Total = $34.50
Step-by-step explanation:
Multiply 29.99 by .15 to find the tip.
Then add the tip to the original number.
Even the measure ofAngle six is 62 what is the measure of angle five
∠5 = 118
Step-by-step explanation:
If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.
A straight line is equal to 180 so if we do...
[tex]180-62[/tex]
= 118.
∠5 will be equal to 118.
If we go even further, because vertical angles are congruent...
∠7 = 62
∠8 = 118
Answer:
[tex] m \angle \: 6 = 118 \degree[/tex]
Step-by-step explanation:
[tex]m \angle \: 5 + m \angle \: 6 = 180 \degree.. (straight \: line \: \angle s) \\ \because \: m \angle \: 5 = 62 \degree \\ \therefore \: 62 \degree+ m \angle \: 6 = 180 \degree \\ \therefore \: m \angle \: 6 = 180 \degree - 62 \degree \\ \huge \red{ \boxed{\therefore \: m \angle \: 6 = 118 \degree}}[/tex]
Consider the equation y=-x^2-7x+12
Answer:
y = (x + 4)(x + 3)
Step-by-step explanation:
y = x ^2 + 7x + 12
The two numbers must add up to 7 and has a product of 12, and since the equation is all positive, then the two numbers are positive too.
So y = (x + 4)(x + 3) is the answer.
Check:
y = (x + 4)(x + 3)
y = x(x + 3) + 4(x + 3) distributive property
y = x^2 + 3x + 4x + 12
y = x^2 + 7x + 12
