Answer:
In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
AdditionSubtractionMultiplicationDivisionVariables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:
[tex]x = 7[/tex]
Let suppose the value of the variable x=7 changes to x=10, then the new value will be:
[tex]x = 10[/tex]
Therefore, the correct answer is:
In arithmetic, variables look like letters.

#1: what percent of 78 is 16?
#2: what is 79% of 55?
Answer:
1. 487.5%
2. 43.45
Step-by-step explanation:
Remember the formula for a proportion: ((part)/(whole)) = ((percent)/(100))
1.
The part is given, 78, and the whole is given, 16.
Set up a porportion:
78/16 = percent/ 100
Simplify:
39/8 = percent /100
Cross products
39/8 = percent/100
8percent = 3900
Inverse operations
8percent = 3900
/8 /8
percent = 487.5
487.5%
2.
The percent is given, and the whole is given.
Set up a proportion:
part/55 = 79/100
Cross products
part/55 = 79/100
100part = 4345
Inverse operations
100part = 4345
/100 /100
part = 43.45

The cost in dollars, y, of a large pizza with x toppings from Pat's Pizzeria can be modeled by a linear function. A large pizza with no toppings costs $14.00. A large pizza with toppings costs $17.50.
Given :
A large pizza with no toppings costs $14.00. A large pizza with toppings costs $17.50 .
To Find :
The cost in dollars y, of a large pizza with x toppings from Pat's Pizzeria.
Solution :
Let, equation is :
y = mx + c ....1)
Case 1 : With no toppings.
y = 14 = m(0) + c
c = 14
Case 2 : With 1 toppings i.e x = 1 .
y = 17.50 = m( 1 ) + c
17.50 = m + 14
m = 3.5
Putting value of c and m in equation 1, we get :
y = 3.5x + 14
Hence, this is the required solution.

Step-by-step explanation:
Subtract
8 1/6 -2 and 7 over 82=127 over 2
Convert mixed number to improper fraction
8 1/6= 8x6/6+ 1/6=16+7/8=23/8
Convert mixed number to improper fraction
2 7/8= 2x8/8+7/8=16+7/8=23/8
Find common denominator
49/6-69/24=196-69/24=127/24
24 is the least common multiple of denominators 6 and 8. Use it to convert to equivalent fractions with this common denominator.
Subtract
196/24- 69/24= 196-69/24=127/24
Simplify
127/24= 5 7/24

A 17-ft ladder leans against a building so that the angle between the ground and the ladder is 71°. How high does the ladder reach on the building? (Round your answer to the nearest foot.)
Answer:
there is 16.08 foot high does the ladder reach on the building
Step-by-step explanation:
The computation of the high does the ladder reach on the building is shown below:
Given that
length of the ladder = 17 ft
angle -between the ground and the ladder = 75 degrees
Based on the above information
Here we used the trig-ratio to calculate the same
[tex]Sin \theta = \frac{oppo}{hyp} \\\\Sin 71^{\circ} = \frac{h}{17}[/tex]
0.946 × 17 = h
The height is 16.08 foot
Hence, there is 16.08 foot high does the ladder reach on the building

sorry :(
Hopefully someone fills in the rest of the answers!!!
Answer:
Question 1:
8/12 = 4/6 = 3/x
0.6 = 0.6 = 3/x
It is a similar triangle, therefore 3/x = 0.6
x = 5 because 3/5 = 0.6
Question 2
You did that correct :)
Question 3:
"Check all that apply"
B
D
Question 4
You got question 4 wrong since similar triangles have similar ratio.
8/10 = 8/10 = 10/14
0.8 = 0.8 = 0.7
Correct answer for question 4 is B("No they are not similar because the ratios are not equal")
Question 5
The Quadrilaterals are similar. Therefore:
22.4/14 = 12.8/8 = 12/7.5 = 26/x
1.6 = 1.6 = 1.6 = 26/x
Meaning 26/x = 1.6
x = 16.25
Because 26/16.25 = 1.6
Hope that helps :)

Answer:
FIGURE 1:
x = 118; y = 96
FIGURE 2:
x = 85; y = 65
Step-by-step explanation:
FIGURE 1:
You know that x = 118 because of the Corresponding Angles theorem.
Because of the Exterior Angle Theorem (triangles), you can then figure out what y is with the following equation: y + 22 = 118 to get y = 96.
FIGURE 2:
In this figure, you first need to determine what the third angle in the bottom right triangle is. Using the Triangle Sum Theorem, you would find that the third angle is 70.
Because of the Vertical Angles Theorem, you know that the third angle in the top left triangle is also 70. With this information, you can now solve for x using the Triangle Sum Theorem to get x = 85.
Now that you know x, you can solve for y. The other 3 angles in the quadrilateral in which y is a part of are 90, 110, and 95. These could be figured out using the Linear Pair Postulate, the Vertical Angles Theorem, and the Linear Pair Postulate respectively. Now you can figure out y by using the Quadrilateral Sum Conjecture to get y = 65.

∣x−10015∣∣≤23
where x is a person’s IQ. Solve the inequality to find the IQ scores for the middle 50% of the population.
Answer:
9992≤x 10038Step-by-step explanation:
Given the expression
∣x−10015∣∣≤23, we are to find the range of values of x
since the function is in a modulus sign, it can be expressed as a negative and positive function.
If the function is positive;
x - 10015 ≤23
x ≤23 + 10015
x ≤ 10038
If the function is negative;
-(x-10015)≤23
-x+10015≤23
-x≤23-10015
-x≤-9992
multiply through by -1
x ≥ 9992 (note the inequality sign change)
9992≤x
Combine both inequalities
9992≤x and x ≤ 10038
On combining;
9992≤x 10038
Hence the inequality to find the IQ scores for the middle 50% of the population is expressed as 9992≤x 10038
We want to solve an inequality to find the range of IQ scores for half of the population.
We will find that the range is:
77.15 ≤ x ≤ 123.15
The inequality we need to solve is:
|x - 100.15| ≤ 23
To solve it, we write two inequalities.
x - 100.15 ≤ 23
x - 100.15 ≥ -23
Solving these two, we will get the maximum and minimum of the range.
The maximum is given by:
x - 100.15 ≤ 23
x ≤ 23 + 100.15 = 123.15
The minimum is given by:
x - 100.15 ≥ -23
x ≥ -23 + 100.15 = 77.15
Then the range is:
77.15 ≤ x ≤ 123.15

c.
Gareth will owe the IRS $896.
d.
Gareth will owe the IRS $850.
Answer:

Step-by-step explanation:
just took quiz
The Gareth is single and he has a net taxable income of $54,446 over the last year the employee has collected about $9,100 from him and he has been withheld for the payroll of taxes. Thus the answer is option D that is he will owe the IRS $850.
Calculate the net taxable income that Gareth is expected.As per the data of the table the taxes shows that Gareth's expectations from the taxes are due between 54,400 and 54,500 USD. As the tale mentions the tax of 54,400 and 54,500 dollars he is to do a single filing and his employees want to the total amount of 9,950 dollars to be taxed thus he has ownership of the about 850 dollars.
