Alanna tried to solve an equation step by step. \begin{aligned} 4c&=12\\\\ \dfrac{4c}{4}&=12\cdot4&\green{\text{Step } 1}\\\\ c&=48&\blue{\text{Step } 2} \end{aligned} 4c 4 4c c =12 =12⋅4 =48 Step 1 Step 2 Find Alanna's mistake.
Answer:
Her mistake was in step 1
Step-by-step explanation:
Given the expression solved by Alanna
4c = 12
To get c, we will divide both sides of the equation by 4:
4c/4 = 12/4
c = 12/4
c = 3
Alanna made mistake in step 1 where she divided multiplied the right hand side of the equation by 4 instead of dividing by 4

Aiden cuts a ball of string into 14 equal pieces. The length of each piece of string is 2 1/4 yards. What is the original length of the ball of string?
Answer:
31 1/2 yards
Step-by-step explanation:
In order to calculate the original length of the ball of string we simply need to multiply the length of each piece of string by the total number of strings that were produced from the original ball of string. First, we can turn the 2 1/4 into a single decimal number. Since 1/4 is equal to 0.25 we just add this to 2 to get 2.25, now we can go ahead and multiply this by the 14 total pieces.
2.25 * 14 = 31.5 or 31 1/2 yards

What is the circle?A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
Radius of a circle is the distance from the center of the circle to any point on it's circumference.
Here, SM=OM=7.4 units
Therefore, option B is the correct answer.

Cora went on a shopping trip to Lowell. She purchased a calculator originally priced at $75 but discounted 20%. If sales tax in Lowell is 15%, what was the total cost?
Answer: $69
Step-by-step explanation:
Sales tax is charged after the discount.
The calculator was originally $75 and there is a 20% discount.
The discounted price is:
= 75 * (1 - 20%)
= 75 * 0.8
= $60
Now the sales tax applies. Total cost is:
= 60 * (1 + 15%)
= 60 * 1.15
= $69

Composition of functions~
Answer:
[tex]g(h(-8)) = 119[/tex]
Hence, option B) is true.
Step-by-step explanation:
Given
g(x) = 2x-5
h(x) = x² - 2
To determine
[tex]g(h(-8)) = ?[/tex]
In order to determine g(h(-8)), first we need to determine h(-8), so
substituting x = -8 in h(x) = x² - 2
h(x) = x² - 2
h(-8) = (-8)² - 2
h(-8) = 64 - 2
h(-8) = 62
so we can write
[tex]g(h(-8)) = g(62)[/tex]
now, to determine g(62), substitute x = 62 in g(x) = 2x-5v
g(x) = 2x-5
g(62) = 2(62) - 5
g(62) = 124 - 5
g(62) = 119
so,
[tex]g(h(-8)) = g(62)=119[/tex]
Therefore,
[tex]g(h(-8)) = 119[/tex]
Hence, option B) is true.

Answer:
a) 94°
Step-by-step explanation:
shape is a 5-sided polygon, known as a pentagon
number of degrees inside can be found by taking the number of sides (5), deducting 2 (3) and then multiplying by 180°.
Therefore there are 540° altogether.
add all like terms for all five angles: 24x - 12 = 540
24x = 552
x = 23
m∡P = 4(23) = 2
= 92 + 2
= 94°

It takes 16 people to pull a 30 ton cable wire. How many people would it take to pull a 60 ton cable wire?
The answer to this question is 32
Explanation
16/30 cross multiplies x/60
after you get, 960=30x
then divide by 30 and then you get 32.
or you can just take 16 and multiply it by two since 60 is a multiple of 30.

Let x represent the number of years in 2004 and y represent the number of catalogs Catalogs. Number in 2004. Growth rate Online. 7440. 1293 Print. 3805. -1364
Answer:
The answer is below
Step-by-step explanation:
a) x represents the number of years since 2004 this means that x = 0 represent the year 2004, y represent the number of catalogs. From the table the numbers of catalogs in 2004 are y-intercepts and the slope is the growth rates. Hence the equations are:
y = 1293x + 7440 (1)
y = -1364x + 3805 (2)
b)
y = 1293x + 7440 (1)
y = -1364x + 3805 (2)
Subtract equation 2 from equation 1 to get:
0 = 2657x + 3635
2657x = -3635
Divide through by 2657
x = -1.368
Put x = -1.368 in equation 1:
y = 1293(-1.368) + 7440
y = 5671.1
This means that about 1.4 years before 2004, the number of catalogs where 5671

Hazelhas$100inasavingsaccountthatearns10%interestperyear.Theinterestisnotcompounded.Howmuchwillshehavein1year? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer: See explanation
Step-by-step explanation:
Interest = PRT
Principal = $100
Rate = 10%
Time = 1 year
Interest = PRT = (100 × 10% × 1)
= 100 × 0.1 × 1
Interest = $10
Amount = Principal + Interest
= $100 + $10
= $110
