[tex]= \tt\$570[/tex]
Answer with steps :Money Dayami earns for an hour's work = $10.50
Number of hours Dayami worked last week = 40
Money Dayami would have gotten for her work :
[tex] =\tt 10.50 \times 40[/tex]
[tex] =\tt \$ \: 420[/tex]
Thus, money earned by Dayami for her work = $420
Total sales Dayami made last week = $2050
Money Dayami must have earned as commission :
= 6% of total sales
[tex] = \tt6 \% \: of \: 2500[/tex]
[tex] = \tt\frac{6}{100} \times 2500[/tex]
[tex] =\tt \frac{15000}{100} [/tex]
[tex] =\tt \$150[/tex]
Thus, money Dayami earned as a commission = $150
Dayami's weekly gross salary last week :
[tex] = \tt420 + 150[/tex]
[tex] =\color{plum} \tt \: \$570[/tex]
Thus, total salary = $570
Therefore, Dayami's gross salary last week = $570
In a recent poll, 13% of all respondents said that they were afraid of heights. Suppose this percentage is true for all Americans. Assume responses from different individuals are independent.
a. What is the probability of having 3 randomly selected Americans all say that they are afraid of heights?
b. What is the probability of having none of the 3 randomly selected Americans say that they are afraid of heights?
c. What is the probability of having at least 1 of the 3 randomly selected Americans say that they are afraid of heights?

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Work out the volume of this prism.
Answer:
480 cm³
Step-by-step explanation:
Giveb that :
Area = 40cm²
Height, h = 12 cm
The volume of a prism is the product of it's base area and height, h
Base area = 40cm² ; height = 12cm
Volume = base area * height
Volume = 40cm² * 12cm
Volume = 480cm³

a family buys 5 airline tickets online. the family buys travel insurance that costs $18 per ticket. the total cost is $955. let z represent the price of one ticket. write an equation for the total cost. then find the price of one ticket.
Answer: Equation that represents this situation is 5(x+17) = 1495,
Price of one ticket is 282
Step-by-step explanation:
Here x represents the price of one ticket,
Also, a person bought travel insurance that costs $17 per ticket.
Hence, the total cost of a person = x + 17
⇒ The total cost of 5 person = 5 ( x + 17 )
But, According to the question,
5 ( x + 17 ) = 1495
⇒ x + 17 = 299
⇒ x = 299 - 17
⇒ x = 282

Answer:
Cereal B.
Step-by-step explanation:
To figure out how much it costs per ounce for each cereal, first we need to divide.
Cereal A: $2.25 / 10 = $.225 per ounce
Cereal B: $3.30 / 15 = $.22 per ounce
So, cereal B is less expensive.

Which table represents a quadratic function?
Answer:
D
Step-by-step explanation:
A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

Answer:
y+8 = 2(x-4)
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.

Morgan is reading a 326-page book. The table shows three different plans to finish the book.
Plan Pages to Read Each Day Number of Days Needed
A 10 33
B 20 ?
C 30 11
Part A
Using Plan B, how many days will it take Morgan to finish her book? Enter your answer in the box.
days
Part B
Which explains how to find the number of days it will take Morgan to finish her book using Plan B?
Select all that apply.
A.
Multiply 20 × 16 to get 320, which is not enough days. So multiply 20 × 17 to get 340, which is enough days.
B.
Since 20 pages is halfway between 10 and 30 pages, the number of days must be halfway between 33 and 11 days.
C.
Since 10 pages are added each day from Plan A to Plan B, 10 days must be subtracted from the number of days needed in Plan A.
D.
Divide 326 ÷ 20 to get 16 R6. Round the quotient to the next greater whole number.
E.
Divide 326 ÷ 20 to get 17 R6. Round the quotient to the next greater whole number.
Answer:
Part A
16 and 1/2 or 16 R6, 17 if you round up
Part B

Sam's dad gave him $30 for washing their car. He used the money to buy a basketball for $7.50 and three sports drinks for $2.75 each. Sam also bought a bag of candy. If Sam went home with 13 of the money his dad gave him, how much did the bag of candy cost?
Answer:
Basketball + Sports Drink
$7.50 + $2.75 = $10.25
$10.25 + ? + $13 = $30
30 - 23.25 = 6.75

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define
2(n + 3) - 4 < 6
Step 2: Solve for n
[Addition Property of Equality] Add 4 on both sides: 2(n + 3) < 10[Division Property of Equality] Divide 2 on both sides: n + 3 < 5[Subtraction Property of Equality] Subtract 3 on both sides: n < 2Here we see that any value n smaller than 2 would work as a solution to the inequality.
