Todd uses white tiles and some black tiles to make mosaic the mosaic has a total area of 144 square centimeters each tile has an area of 3 square centimeters how many black tiles did Todd use
Answer:
27 tiles
Step-by-step explanation:
Here is the complete question :
Todd uses 21 white tiles and some black tiles to make a mosaic.the mosaic has a total area of 144 square centimeters. Each tile has an area of 3 square centimeters. How many black tiles did Todd use
Steps to take to determine the answer
Determine the total area of the white tiles used. This can be determined by multiplying the number of white tiles by the area of a tilesubtract the area of the white tiles from the total area of the mosaic. Divide the answer derived in the previous step by 3Area of the white tile = area of each tile x total white tiles used
3 x 21 = 63cm²
144cm² - 63cm² = 81cm²
Number of black tiles used = 81cm² / 3cm² = 27 tiles
Samuel is a teacher and takes home 75 papers to grade over the weekend. He can grade at a rate of 7 papers per hour. How many papers would Samuel have remaining to grade after working for 8 hours?
Answer: 19
Step-by-step explanation:
75 papers need to be marked
He grades 7 papers per hour
To find out how many paper he graded in 8 hours:
7 x 8
(7 is the number of papers graded in an hour)
(8 is the number of hours)
7 x 8 = 56
(56 is the number of papers he graded in 8 hours)
Now, there was a total of 75.
To find the remaining number of test sheets:
75 - 56
(75 is the total number of papers)
(56 is the number of papers graded)
75 - 56 = 19
Therefore, there are 19 papers remaining to grade.
The width of a rectangle is 7 feet and the diagonal legnth of the rectangle is 11 feet. Which measurement is closest to the length of this rectangle in feet?
Answer:
8.49 feet
Step-by-step explanation:
Characteristics of a rectangle
A rectangle is a quadrilateral It has two parallel sides the diagonals of a rectangle bisect each other and they are equal in lengthOne diagonal of a rectangle divides a rectangle into two right angled triangles. Thus, the length of the rectangle can be determined using the Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length = ?
b = width = 7
c = diagonal = 11
7² + a² = 11²
49² + a² = 121²
a² = 121 - 49
a² = 72
calculate the square root of 72
a = 8.49 feet
Answer:
8.49 feet

Mr. Rector and Ms. Mitchell are grading papers. Mr. Rector can grade 24 papers in 10 minutes. Ms. Mitchell can grade 30 papers in 8 minutes. How many more papers per minute can Ms. Mitchell grade?
Answer: 1.35
Step-by-step explanation:
Answer:
1.35
Step-by-step explanation:
We need to identify our independent variables and dependent variables.
The number of papers graded depend on the amount of time.
The amount of time is the independent variable
The papers graded depends us the dependent variable
Divide the independent variable by the dependent variable to find papers per minute
For Ms.Mitchell the papers per minute is
For Mr.Rector, the papers per minute is
Subtract 2.4 from 3.75.
The answer is 1.35

Determine the radius of the circle below.
Answer:
r = 22.629
Step-by-step explanation:
Using the Pythagorean theorem:
(35 + r)² = 53² + r²
1225 + 70r + r² = 2809 + r²
subtract r² from each side of the equation:
1225 + 70r = 2809
subtract 1225 from each side:
70r = 1584
r = 22.629

The area of a sector is. What does the variable n represent?
the number of degree in the central angle
N is the degree of the central angle of the sector.
What is sector in an angle?The sector angle is the angle subtended between two radii of circle to the center of Circle.
If the radius of the circle is 10 inches, and the central angle of the sector is 90 degrees, the area of the sector can be found as follows:
90/360 * (3.14 * 10^2).
Following the order of operations, the equation proceeds as follows:
1/4 * (3.14 * 100) = 1/4 * 314 = 78.5.
Thus, the area of the sector is 78.5 square inches.
The formula to find the area of a sector is A = N/360 x (pi x r^2).
A sector is a section of a circle. In the formula given, A is the area of the sector,
N is the degree of the central angle of the sector, pi is an irrational number that can be rounded to 3.14, and r is the length of the radius of the circle.
Hence, N is the degree of the central angle of the sector.

Ray is a member of a card club. He pays a fixed fee of $45. He must pay $6 for every game he attended. He attends 12 games. What is the total amout that he payed
Answer:
$117
Step-by-step explanation:
Create an equation to represent the situation, where x is the number of games he attended, and y is the cost
y = 6x + 45
Solve for the amount he paid by plugging in 12 as x
y = 6x + 45
y = 6(12) + 45
y = 72 + 45
y = 117
So, Ray paid $117

Given:
Output = 5 times input
To find:
The graph for the given statement.
Solution:
We know that, y-axis represents the output and x-axis represents the input.
Let y be the output and x be the input. Then the given statement can be written as
[tex]y=5x[/tex]
Here, the slope of the line is 5 because the value of [tex]m[/tex] is 5 on comparing the equation with [tex]y=mx+b[/tex].
It means the line is steeper because the vertical change is greater than the horizontal change.
Therefore, the correct option is A.

Triangle Q S R is shown. Angle Q S R is a right angle. Altitude s is drawn from point S to point T on side Q R to form a right angle. Side Q S is labeled r and side W R is labeled q. The length of Q T is 10 and the length of R T is 4. What is the value of q? 4 StartRoot 5 EndRoot 2 StartRoot 14 EndRoot 20 StartRoot 5 EndRoot
*The diagram is in the attachment
Answer:
q = 2√14
Step-by-step explanation:
To determine the value of q, apply the leg rule/geometric mean theorem, which is:
Hypotenuse/leg = leg/part
Hypotenuse = 10 + 4 = 14
Leg = q
Part = 4
Plug in the values into the equation:
14/q = q/4
Cross multiply
q*q = 14*4
q² = 56
q = √56
q = √(4*14)
q = 2√14
Answer:
q = 2√14
