Step-by-step explanation:
we can proceed to model the cost of Billy's Boat Rental Company
let y be the cost
let x be the number of rentals
y=105+9.5x----1
Also, the cost of Billy's Boat Rental Company
y=14.75------2
the question is "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"
we have to equate the two cost and solve for x
105+9.5x=14.75
105-14.75+9.5x=0
90.25+9.5x=0
9.5x=-90.25
divide both sides by 9.5 we have
x=-90.25/9.5
x=9.5

Solve for b:4 = -2/3(5) + b
Answer:
[tex]\frac{22}{3}[/tex] = b
or
7[tex]\frac{1}{3}[/tex] = b
(they are the same value, just different ways of writing it)
Step-by-step explanation:
4 = -[tex]\frac{2}{3}[/tex] (5) + b
simplify
4 = -[tex]\frac{10}{3}[/tex] + b
now use inverse operations
4 = -[tex]\frac{10}{3}[/tex] + b
+[tex]\frac{10}{3}[/tex] +[tex]\frac{10}{3}[/tex]
[tex]\frac{22}{3}[/tex] = b

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters. centimeters of velve
Given:
Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long.
Velvet purchased by first customer = 120 centimeters
Velvet purchased by second customer = 14 meters
To find:
The remaining velvet in Malik's shop.
Solution:
We know that,
1 meter = 100 cm
Using this conversion, we get
32 meter = 3200 cm
14 meter = 1400 cm
Now,
Remaining velvet in Malik's shop = (3200 - 120 - 1400) cm
= 1680 cm
Therefore, the remaining velvet in Malik's shop is 1680 cm.

1. add negative fraction with positive fraction
-7/8 + 1/4 = ?
2. add negative decimal with positive decimal
-12/5 + 15.3 = ?
Given parameters:
1. [tex]-\frac{7}{8} + \frac{1}{4}[/tex]
[tex]-\frac{7}{8} + \frac{1}{4}[/tex]; find the LCM = 8
= [tex]\frac{-7 + 2 }{8}[/tex]
= [tex]\frac{-5}{8}[/tex]
2. [tex]-\frac{12}{5} + 15.3[/tex]
Make the fraction decimal;
[tex]-\frac{12}{5}[/tex] = -2.4
So;
-2.4 + 15.3 = 12.9
Planet Earth has an approximate diameter of 1.2742 · 10 10 millimeters. The sun has a diameter of 1.391 · 10 6 kilometers. Part I: Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters? Part II: Approximate how many times greater the sun's diameter is than planet Earth's.
Answer:
Part 1:
Due to these magnitudes are too big, it is better to use km as a unit of diameter measurement.
Part 2:
The diameter of the sun is approximately 109 times the diameter of the earth.
Step-by-step explanation:
Part 1:
Due to these magnitudes are too big, it is better to use km as a unit of diameter measurement.
So we can rewrite the diameter of the Earth in terms of km, knowing that 1 km = 1000000 mm.
[tex]D_{E}=1.2742\times 10^{10}mm*\frac{1km}{1000000mm}=1.2742\times 10^{4} km[/tex]
Part 2:
We can divide each diameter to find the relation between them.
[tex]\frac{D_{S}}{D_{E}}=\frac{1.391\times 10^{6} km}{1.2742\times 10^{4} km}=109.2[/tex]
Therefore the diameter of the sun is approximately 109 times the diameter of the earth.

Distance Between two Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
We are given the points (5, 14) and (−3, −9). Substituting into the formula:
[tex]d=\sqrt{(-9-14)^2+(-3-5)^2}[/tex]
[tex]d=\sqrt{(-23)^2+(-8)^2}[/tex]
[tex]d=\sqrt{529+64}[/tex]

The Family Arts Center charges $22 for adults, $13 for senior citizens, and $5 for children for their live performance on Sunday afternoon. This past Sunday, there paid revenue was $8526 for 670 tickets sold. There were 49 more children than adults. How many children attended. A 205 B 247 C 208 D 257
Answer:
257
Step-by-step explanation:
Let the number of Adults = x
Number of senior citizens = y
Number of children = z
x + y + z = 670 tickets
The Family Arts Center charges $22 for adults, $13 for senior citizens, and $5 for children for their live performance on Sunday afternoon.
$22 × x + $13 × y + $5 × z = $8526
22x + 13y + 5z = 8526
There were 49 more children than adults.
z = x + 49
x + y + z = 670 tickets
x + y + x + 49 = 670
2x + 49 + y = 670
y = 670 - 2x - 49
We substitute
22x + 13y + 5z = 8526
22x + 13(670 - 2x - 49) + 5(x + 49) = 8526
22x + 8710 - 26x - 637 + 5x +245 = 8526
22x + 5x - 26x + 8710 - 637 + 245 = 8526
x + 8318 = 8526
x = 8526 - 8318
x = 208
The number of Adults = 208
The number rod children is calculated as:
z = x + 49
z = 208 + 49
z = 257
The number of children = 257

Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches. Which is an effective estimation strategy for finding the sum of the two lengths? Round 39.75 to 30 and 47.6 to 40, then add. Round 39.75 to 40 and 47.6 to 48, then add. Add 47.6 and 39.75, then round the answer. Subtract 39.75 from 47.6, then round the answer.
Answer:
Add 47.6 and 39.75, then round the answerStep-by-step explanation:
If Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches, the effective strategy of finding the sum of the two lengths is to:
1) First is to add the two values together
47.6 + 39.75
= (47+0.6)+(39+0.75)
= (47+39)+(0.6+0.75)
= 86 + 1.35
= 87.35
2) Round up the answer to nearest whole number.
87.35 ≈ 87 (note that we couldn't round up to 88 because the values after the decimal point wasn't up to 5)
Option C is correct
Answer:
B. Round 39.75 to 40 and 47.6 to 48, then add.

Function y=(x-1)(x-1) satisfy the condition for the given graph.
What is function?A function is a combination of different types of variable and constants in which for the different values of x the value of function y is unique.
According to given graph,
At x =0, the value of y = 1,
So substitute x = 0 in the given options,
Which option gives y = 1 will be correct option.
(A)
y = x² - 5x + 6
y = 0 -5x0 + 6
y = 6
(B)
y = (x-1) (x-1)
y = (0-1)x (0 - 1)
y = 1
(C)
y=(x-3) (x+1)
y = (0-3)x(0+1)
y = -3
