Matt is cutting quilt squares measuring 3 inches on each side. He wants to use them to make a rectangular wall hanging measuring 1 yard by 212 feet. How many quilt squares does he need?
Answer:
Matt will need 10176 square quilts to cover the wall
Step-by-step explanation:
To answer this perfectly, we will have to first convert everything to the same unit.
dimensions of the quilt squares = 3 inches
Length of the wall = 1 yard = 36 inches
Breadth of the wall = 212 feet = 2544 inches.
The next step, is to find the area of the wall that Matt is covering.
Area of wall = length X breadth = 36 X 2544 = [tex]91584in ^{2}[/tex]
We will also find the area of the square quilts. This is given as length X length = [tex]3^{2}[/tex]=[tex]9 in^{2}[/tex]
to get the number of square quilts that will cover that area, we will have to divide the area of the wall by the area of the quilts
= 91584 /9 = 10176 quilts
Matt will need 10176 quilts to cover the wall

help me plz and 5x + 25 > 75
Answer:
x > 10
Step-by-step explanation:
Isolate the variable, x. Treat the > sign as a equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 25 from both sides:
5x + 25 (-25) > 75 (-25)
5x > 75 - 25
5x > 50
Next, divide 5 from both sides:
(5x)/5 > (50)/5
x > 50/5
x > 10
x > 10 is your answer.

A car is traveling at 47 mph. If its tires have a diameter of 27 inches, how fast are the car's tires turning? Express the answer in revolutions per minute. Round to two decimal places
Answer:
3676.44 rad/min
Step-by-step explanation:
It is a problem about the angular speed of the car's wheel.
You can calculate the angular speed by using the following formula, which relates the tangential speed of the wheels (the same as the speed of the car) with the angular speed:
[tex]\omega=\frac{v}{r}[/tex] ( 1 )
v: speed of the car = tangential speed of the wheels = 47mph
r: radius of the wheels = 27/2 in = 13.5 in
you change the units of the speed:
[tex]47mph*\frac{63360in}{1mille}*\frac{1h}{60min}=49632\frac{in}{min}[/tex]
next, you replace the values of v and r in the equation (1):
[tex]\omega=\frac{v}{r}=\frac{49632in/min}{13.5in}=3676.44\frac{rad}{min}[/tex]
Then, the car's tires are turning with an angular speed of 3676.44 rad/min

log3(5x+1)=4 A.) x = 5 B.) x = 16 C.) x = 4 D.) x = 3
Answer:
B) x=16
Step-by-step explanation:
The 3 is the base, the expression in the parenthesis is the argument and the 4 is the exponent
We also know that [tex]base^{exponent}[/tex] = argument
so therefore the new equation is [tex]3^{4}[/tex] = 5x+1
3 to the fourth power is 81
so 81=5x+1
then solve algebraically
A little help plzzzzzz
Answer:
D.
Step-by-step explanation:
Since it's absolute value, it makes the number positive
Answer:
I'm pretty sure it would be the last option because |-2| is the absolute value of -2, which is 2 because the absolute value of a number is it's distance from 0 on a number line. The distance between A and C on the number line is 2, so this is the answer.
How many solutions does this equation have?
–8 + t = –t + 10
Answer:
One
Step-by-step explanation:
Since (1) is the highest exponent value, there can only be one solution.
IF t^2 then there would be two answers.
Answer:
One solution
Step-by-step explanation:
To find the amount of solutions, you must solve first:
-8 + t = -t + 10
First, add t to both sides:
-8 + 2t = 10
Add 8 to both sides:
2t = 18
Divide both sides by 2:
t = 9
Since there has been a solution to this equation, that means there's only one solution.
Is it possible to triangulate a quadrilateral and get more or fewer than two triangles? Determine whether this investigation verifies that the sum of the interior angles of a quadrilateral is always 360°.
Answer:
No.
Step-by-step explanation:
It’s not possible. No matter what type of quadrilateral it is, there will only be two triangles formed, verifying that the sum of the interior angles of a quadrilateral is always 360°.
It’s not possible to triangulate a quadrilateral and get more or fewer than two triangles. It is verifies that the sum of the interior angles of a quadrilateral is always 360°.
What is a quadrilateral?Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.
It’s not possible to triangulate a quadrilateral and get more or fewer than two triangles. No matter what type of quadrilateral it is, there will only be two triangles formed.
We know that The sum of internal angle of a quadrilateral is 360°.
The sum of angle in a triangle is 180°. By Adding the two triangle angle together, we will get the sum as 360°.
The Sum of the interior angle of a polygon = 180(n-2) .
It is verifies that the sum of the interior angles of a quadrilateral is always 360°.

Zech deposited $5,600 in an account, which compounded 1.9 percent quarterly, and left it there for 10 years. What was the amount in the account at the end of 10 years? Round to the nearest dollar.
Answer:
$6769
Step-by-step explanation:
To calculate the amount, we make use of the compound interest formula
A = P(1+r/n)^nt
where A is the amount which we are to calculate
P is the amount deposited which is $5,600
r is the rate which is 1.9% or 1.9/100 = 0.019
t is the number of years = 10
n is the number of times the interest is compounded per year which is 4(quarterly means every 3 months and there are 4 quarters in a year)
Plugging all these values, we have
A = 5,600(1+ 0.019/4)^40
A = 5,600( 1 + 0.00475)^40
A = 5,600(1.00475)^40
A = $6768.75
Which is $6769 to the nearest dollars
A police department used a radar gun to measure the speed of a sample of cars on the highway. Assume that the distribution of speeds is approximately Normal with a mean of 71 mph and a standard deviation of 8 mph. Using this distribution what is the z-score of a 65-mph speed limit?
Answer:
The z-score of a 65-mph speed limit is -0.75
Step-by-step explanation:
Here, we want to calculate the z-score
To calculate the z-score, we make use of the z-score formula
Mathematically;
z-score =(x-mean)/SD
from the question we identify the values as x = 65 mph, mean = 71 mph, Standard deviation(SD) = 8 mph
Plugging these values into the equation above, we have
z-score = (65-71)/8 = -6/8 = -0.75

What is the volume, in cubic centimeters, of a
cylinder that has a height of 15 cm and a
diameter of 12 cm?
Answer:
3cm
Step-by-step explanation:
Answer:
The answer is 540π cm³ or 1700 cm³.
Step-by-step explanation:
Given that the volume og cylinder is V = π×r²×h where r represents radius and h is height. The diameter is 12 cm so the radius is 6 cm. Then you have to substitute it into the formula :
V = π × r² × h
Let r = 6 cm,
Let h = 15 cm,
V = π × 6² × 15
= π × 36 × 15
= 540π cm³
= 1700 cm³ (3s.f)
