Answer:
57.95
Step-by-step explanation:
The area of the floor is (6.1 ft)(9.5 ft) = 57.95 ft². This will be the minimum that Marcus will want to purchase.
If we assume that tiles come in pieces 1 ft square, then Marcus will need a minimum of 58 square feet.
If Marcus does not want to piece together any tiles at the edges, he will want to purchase 10×7 = 70 square feet of tile.

Ashley is looking for ways to save some spending money for her senior class trip to Mexico. She has decided to
stop eating chocolate for one whole year and instead save any money she would have spent on chocolate for the
trip. If Ashley typically spends $2.50 a week on chocolate, how much money, not accounting for interest, can she
expect to save for the trip in exactly one year? $|||
Answer:
She would have 130 dollars
Step-by-step explanation:
There are 52 weeks in a year. So multiply 2.50 by 52. She would have 130 dollars.
Ashley can expect to save $130 for the trip in exactly one year.
Ashley decided to stop eating chocolate for one whole year to save some spending money for her senior class trip to Mexico.
The amount Ashley typically spends a week on chocolate = $2.50.
We have to find how much Ashley can save in one year if we can save $2.50 per week.
How many weeks in a year?There are 365 days in a year and we have 7 days in a week.
If we divide 365 by 7 we get,
365 / 7 = 52.14.
which means 52 weeks.
So in one year, we have 52 weeks.
We can write this statement "Ashley typically spends $2.50 a week on chocolate" as :
1 week = $2.50
Multiply by 52 on both sides.
we get,
52 x 1 week = 52 x $2.50
52 weeks = $130
Thus, we can say that in one year Ashley can save around $130 if she saves $2.50 in a week.

Write an equation of line in point slope form containing (-1,1) and (4,-9)
Help!!!!!!!!!!!!!!!!!
9Answer: Y-1=-2(X+1) OR Y+9 = -2(X-4)
Step-by-step explanation:
Point slope form is Y-Y1=m(X-X1)
Slope (M) is (Y2-Y1)/(X2-X1)
SO M= (-9-1)/(4--1)
-10/5
M= -2
Answer:
y - 1 = -2 (x + 1)
Explanation:
point slope form: (y - y1) = m (x - x1)
m is the slope. To find m the formula is:
(y2 - y1) / (x2 - x1)
The given ordered pairs are: (-1,1) and (4,-9)
y2 is the y in the second ordered pair (-9)
y1 is y in the first ordered pair (1)
x2 is x in the second ordered pair (4)
x1 is x in the first ordered pair (-1)
= (-9 - 1) / (4 +1)
= -10/5
m = -2
Now plug m (-2), y1 (1), and x1 (-1) into the point slope form
y - 1 = -2 (x - -1)
y - 1 = -2 (x + 1)

You use the equation $y=0.18x$ to calculate the tip $y$ (in dollars) that you add to a bill for $x$ dollars. a. Solve the equation for $x$ . The rewritten equation is $x=$ . b. Find the amount of the bill (not including tip) when your tip is $4.95. The bill is $\$$ .
Answer:
Step-by-step explanation:
Given the equation y = 0.18x, to solve for x, we will make the variable x as the subject of the formula from the equation given.
From the equation y = 0.18x
Divide both sides by the coefficient of x i.e 0.18
y/0.18 = 0.18x/0.18
y/0.18 = x
Hence the function of the variable x = y/0.18
b) Given the amount of the bill as y and x is the tip in dollars.
Given y = $4.95, we are to substitute the value of y = $4.95 into the resulting function in (a) to get x as shown;
Since x = y/0.18
x = $4.95/0.18
x = $27.5
Hence the bill is $27.5

Step-by-step explanation:
We are given the expression:
[tex]\frac{-8(13-37)}{6}[/tex]
and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24
[tex]\frac{-8(-24 )}{6}[/tex]
Next, multiply -8 and -24.
⇒ -8*-24= 192
[tex]\frac{192}{6}[/tex]
Finally. divide 192 by 6.

Corrected Question:
The length of a rectangle is (t – 8) units, and its width is (t + 11) units. Which expression can represent the area of the rectangle?
Answer:
t² + 3t - 88
Step-by-step explanation:
Given:
Rectangle of;
length = (t - 8) units
width = (t + 11) units
The area A of a rectangle is given by;
A = length x width ----------------------------------(i)
Substitute the given length and width into equation (i) as follows;
A = (t - 8) x (t + 11) [expand the brackets]
A = t² -8t + 11t - 88
A = t² + 3t - 88
Therefore, the area is
(t² + 3t - 88) square units

Three equal-sized cardboard boxes are stacked on top of each other. Each box is 56.4 cm in height.
What is the combined height of the 3 stacked boxes?
18.8 cm
59.4 cm
112.8 cm
169.2 cm
Answer:
169.2cm
Step-by-step explanation:
56.4cm + 56.4= 112.8+ 56.4= 169.2cm
The combined height of the 3 stacked boxes will be 169.2 cm so option (D) will be correct.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
Height of one box = 56.4 cm
So,
Height of two boxes = Height of one box + Height of one box
It means
Height of three boxes = Height of one box + Height of one box + Height of one box
So,
Height of three boxes = 56.4 + 56.4 + 56.4
Height of three boxes = 169.2 cm
Hence "The combined height of the 3 stacked boxes will be 169.2 cm".

Segment EC bisects segment AD at C. Find the value of “x," AD = 6x - 4 and AC = 4x - 3, and the measure of CD.
Answer: The value of x=1.
Measure of CD =1 unit.
Step-by-step explanation:
Given: Segment EC bisects segment AD at C.
That means , EC divided AD into two equal parts AC and CD,
i.e. [tex]AC=\dfrac{AD}{2}[/tex]
Also it is given that [tex]AD = 6x - 4[/tex] and [tex]AC = 4x - 3.[/tex]
then, we have
[tex]4x-3=\dfrac{6x-4}{2}\\\\\Rightarrow\ 4x-3= 3x-2\\\\\Rightarrow\ 4x-3x=-2+3\\\\\Rightarrow\ x= 1[/tex]
So, the value of x=1.
Now, CD = AC = 4(1)-3 =4-3 =1 unit.
Hence, Measure of CD =1 unit.

Answer:
((I do not have the answers for one, two, or four))
3.)
•What do you know?
-It’s about 425 miles from San Jose to Los Angeles and 320 miles from San Jose to Santa Barbara.
•What do you want to find out?
-How many miles it is from Santa Barbara to Los Angeles.
•What kind of answer do you expect?
-If using variable, I expect that I will get the number of miles from one city to the other.
5.)
425 = 320 + X
6.)
425 = 320 + X

You are at a family reunion and the cooler contains ten bottles of soda; four Sprite, three Dr. Pepper, and three Cherry Coke. Three times, you randomly pick up a drink for your grandmother. The first time, you get a Cherry Coke. The second and third times, you get Dr. Pepper. What is the probability of getting Dr. Pepper the fourth time and then an Cherry Coke the fifth time without replacement?
Answer:
Probability of getting Dr. Pepper the fourth time = [tex]\frac{1}7[/tex]
Probability of getting a cherry coke the fifth time = [tex]\frac{1}{3}[/tex]
Combined probability = [tex]\frac{1}{21}[/tex]
Step-by-step explanation:
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
It is given that first time a Cherry coke is chosen and it is not replaced.
So, number of cherry coke left = 2
Dr. Pepper is chosen twice and is not replaced, so
Number of Dr. Pepper left = 3 - 2 = 1
Total number of soda left = 10 - 3 = 7
So, probability of getting Dr. Pepper the fourth time = [tex]\frac{1}7[/tex]
Now, total number of soda left = 7 - 1 = 6
Probability of getting a cherry coke the fifth time = [tex]\frac{2}{6} = \frac{1}{3}[/tex]
The combined probability = probability of getting Dr. Pepper the fourth time multiplied with Probability of getting a cherry coke the fifth time
[tex]\Rightarrow \dfrac{1}7 \times \dfrac{1}{3} = \dfrac{1}{21}[/tex]

A square sandbox has an area of 75 square feet. Estimate the length of one of the sides of the
sandbox. Round to the nearest tenths place.
Answer:
8.7
Step-by-step explanation:
Since a square has equal side lengths, the formula for area is s^2, where s stands for side. Since we are given the area, s^2=75 square feet. Take the square root of both sides to get s is equivalent to the square root of 75 square feet. When this becomes a decimal, it is 8.66 feet. Since we are supposed to round to the nearest tenths, it rounds up to 8.7 feet per side length
what values of a and b would make shown below have infinitely many solutions aX +6=-3x+b
Answer:
a = -3, b = 6
Step-by-step explanation:
ax + 6 = -3x + b
If a = -3 and b = 6, then the equation would be -3x + 6 = -3x + 6, which would have infinitely many solutions.
If we isolate x, we have (a + 3) x = b - 6. We want the equation to be 0 = 0 for infinitely many solutions, so a has to be -3 and b has to be 6.
