Answer:
98 [tex]cm^{2}[/tex]
Step-by-step explanation:
The formula for the area of a square when given the diagonal is:
A = [tex]\frac{1}{2}[/tex] [tex]d^{2}[/tex] Where d is the value of the diagonal so it becomes:
0.5 × 14 × 14
This is equal to 98 [tex]cm^{2}[/tex].

When I started here, there were 500 employees. Since then, we have added 35% more employees, so we now have a total of ______ employees
Answer: 675
Step-by-step explanation:
Since the starting amount of employees is 500 we can say that 100%=500.
Adding 35% more employees means that we're adding 35% to the existing 100%, which means we need to find 135% of 500.
To solve we must multiply 135% by 500. 135% as a decimal is 1.35, so we multiply 1.35(500)=675.
Therefore, they now have a total of 675 employees.

Find two given numbers in a given ratio such that the sum of their squares is to their difference in a given ratio. Ratios being 3 : 1 and 10 : 1.
Answer: a=6 and b=2
Step-by-step explanation:
Let say A and b the 2 numbers.
[tex]\dfrac{a}{b} =\dfrac{3}{1} \Longrightarrow\ a=3b\\\\\dfrac{a^2+b^2}{a-b} =\dfrac{10}{1} \Longrightarrow\ (3b)^2+b^2=10*(3b-b)\\\\\Longrightarrow\ 10*b^2=10*2b\\\\\Longrightarrow\ b=2\\\\\Longrightarrow\ a=6\\\\[/tex]

The trolley rolled at a rate of 10 feet per second how far does it go in a minute
9514 1404 393
Answer:
600 feet
Step-by-step explanation:
There are 60 seconds in a minute, so the trolley travels 60 times as far as it does in one second.
(60 seconds/minute) × (10 feet/second) = 600 feet/minute
The trolley goes 600 feet in a minute.

What is the product?
Answer:
product is the result of multiplication or an expression that identifies factors to be multiplied..
The product of the given expression (7x²)(2x³ + 5)(x² - 4x - 9) is,
[tex]14x^{7} - 56 x^6 - 126 x^5 + 35x^{4} - 140x^{3} - 315 x^2[/tex]
The product between expressions can be defined as the outcome or result obtained by multiplying two or more numbers, terms, or quantities together. It represents the combined value or the total when multiple factors are multiplied.
The given expression is,
(7x²)(2x³ + 5)(x² - 4x - 9)
Multiplying the first two expressions,
[tex](7 \times 2 x^{2+3} + 7\times 5x^2)(x^2 -4x -9)\\(14 x^5 + 35 x^2)(x^2 -4x -9)\\[/tex]
Now again multiplying these two expressions
[tex]14x^{5+2} - 4 \times 14 x^5 - 14 \times 9 x^5 + 35x^{2+2} - 35 \times 4x^{2+1} - 35 \times 9 x^2[/tex]
Simplifying this we get,
[tex]14x^{7} - 56 x^6 - 126 x^5 + 35x^{4} - 140x^{3} - 315 x^2[/tex]
Hence,
The product of the given expression is,
[tex]14x^{7} - 56 x^6 - 126 x^5 + 35x^{4} - 140x^{3} - 315 x^2[/tex] .

Write 0.2 repeating as a fraction in simplest form.
0.2 Repeating Decimal is 2/9 as a Fraction
Answer:
2.9
Step-by-step explanation:
We let 0.2 be x.
Since x is recurring in 1 decimal places, we multiply it by 10.
10x = 2.2
Next, we subtract them.
10x - x = 2.2 - 0.2
9x = 2
Lastly, we divide both sides by 9 to get x as a fraction.
Answer: x = 2.9 or 2/9.
Please help! I'm stuck on this big ideas math problem and I can't figure it out. Need to learn this and solve ASAP! :)
Answer:
a) greater than 20
b) 20 is the estimate (round all the three other numbers and add, then subtract from 80 because 20, the average, times the four meetings is 80)
c) You can check your estimate by adding all of the numbers and subtracting the answer by 80. 18 + 17 + 21 = 56. 80 - 56 = 24
24 is closer to 20 than 30, so our estimate is correct.

====================================================
Explanation:
Refer to the diagram below. The rectangle MATH has the diagonal MT that cuts the rectangle into two identical right triangles.
We then use the pythagorean theorem to find the length of the hypotenuse MT.
a^2 + b^2 = c^2
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
c^2 = 676
c = sqrt(676)
c = 26
Segment MT is 26 cm long.
This applies to the other diagonal AH as well.

6. Sam is buying tickets to a movie
online. The price of one ticket is $8.50.
An equation showing the total cost is
C = 8.50t +3.50 where t is the
number of tickets and $3.50 is a
convenience fee. What is the total cost
if he buys 4 tickets?
What’s the answer to this problem?
Answer: C = $37.5
Step-by-step explanation:
Given information
Price of one ticket = $8.50
Convenience fee = $3.50
Number of tickets = 4
Given expression
C = 8.50t + 3.50
Substitute the value of the ticket into the expression
C = 8.50 (4) + 3.50
Simplify by multiplication
C = 34 + 3.5
Simplify by addition
C = $37.5

Answer:
B. 208.75 gallonsStep-by-step explanation:
Let the volume of used water is x.
We have:
526.8 - x = 318.05x = 526.8 - 318.05x = 208.75Correct choice is B

Thr area of a square is 36 centimeters what is the length of each square
Answer:
6 cm
Step-by-step explanation:
The area of a square is its side squared(multiplied by itself). In order to find the length of the square, you would need to find a number which is multiplied by itself to get 36. This number is 6, meaning the length of the square is 6 cm.
