Evaluate x3−y2 if x=2 and y=34
Answer:
- 62Step-by-step explanation:
Evaluate x3−y2 if x=2 and y=34
substitute x=2 and y=32 into the expression:
= x3 - y2
= (2)3 - (34)2
= 6 - 68
= -62
An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression x³−y², when x=2, y=34 is −1,148.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the expression x³−y² and the value of the expression when x=2 and y=34 can be calculated by substituting the values in the expression. Therefore, the expression can be written as,
x³ − y²
Substitute the value of x and y in the expression,
= (2)³ − (34)²
Opening the bracket,
= 8 − 1,156
= −1,148
Hence, the value of the expression x³−y², when x=2, y=34 is −1,148.

We can break down the problem first. The beginning of the problem is...
-2-(-4)
Two negatives make a positive. An equivalent way to say this is
-2+4
-2+4=2
Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!

Answer:

Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
(4)
Here d = 18, thus
C = 18π in
(5)
Here C = 50π, thus
πd = 50π ( divide both sides by π )
d = 50 in
The radius r is one half of the diameter , thus
r = 50 ÷ 2 = 25 in
George is making brown paint he wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio. In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue. How many quarts of yellow does he need
Answer:
3/4 quarts of yellow paint is needed
Step-by-step explanation:
From the question, we are told that:
In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue.
3 quart of Purple paint mix requires 2quarts of red paint and 1 quart of blue paint.
We are also told that:
When George wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio.
This means 1 Purple paint to 1 Yellow paint
4/4 quarts of Yellow paint = 1 yellow paint
3/4 quarts of Yellow paint = 3/4 quarts of purple paint

Write the equation of the line with the slope of 10 that goes through the point 8,-2 in point slope form
Answer:
y=10x+28
Step-by-step explanation:
y=10x+28
y=(10*-2)+28
y=-20+28
y=8
The linear equation of the line is y + 2 = 10(x - 8)
How to determine the line equation?The slope is given as:
m = 10
The point is given as:
(x1, y1) = (8, -2)
The equation in point slope form is calculated as;
y - y1 = m(x - x1)
So, we have:
y + 2 = 10(x - 8)
Hence, the linear equation of the line is y + 2 = 10(x - 8)

Answer:
11 1/5 feet!
Step-by-step explanation:
He needs a total of 27 9/10 feet! 11 1/2 + 5 1/5 is 16 7/10 feet! If we need 27 9/10 feet, we subtract 16 7/10 ft from 27 9/10 ft to get 11 2/10, which we can reduce 2/10 to be 1/5.
So, he needs 11 1/5 feet of wood more to build the doghouse for his new puppy!

Hank invested $50,000 in a mutual fund that earns 7% interest compounded annually. How much interest did he earn after 10 years?
F)$35,000
G)$48,357.57
H)85,000
J)98,357.57
Answer:
F $35,000
Step-by-step explanation:
3,500 is 7% of 50,000 3500 multiplied by 10 years= 35,000
9514 1404 393
Answer:
G) $48,357.57
Step-by-step explanation:
The future value formula can be used to find the account value:
FV = P(1 +r)^t
where P is invested at annual rate r for t years.
FV = $50,000(1.07^10) ≈ $98,357.57
The amount of interest earned is the difference between this value and the value of the initial investment:
interest = $98,357.57 -50,000 = $48,357.57
Hank earned $48,357.57 in interest after 10 years.
_____
At 7% interest, the "rule of 72" tells you the doubling time of the account is about 72/7 = 10.3 years. That is the account value will be not quite double the original investment after 10 years. So, the amount of interest earned is only slightly less than $50,000. If the account earned simple interest, the interest earned would be $35,000. Only one answer choice is more than $35,000 and less than $50,000.

Chris wants to fence a square area of his yard for his dogs. if he wants the area of the square to be 121 square feet, what does the perimeter of the square need to be?
please i'm about to fail
Answer: the perimeter of the square is 44
Answer:
44 ft
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Here A = 121, thus
s² = 121 ( take the square root of both sides )
s = [tex]\sqrt{121}[/tex] = 11
Perimeter = 4 × 11 = 44 ft

Below is a scale drawing of a stage that Syla is designing. A rectangle with length 8 centimeters and width 5 centimeters. Using the scale 1 cm : 7 m, Syla calculated the width, or the shorter side of the stage, to be 35 m. She decides to change the scale to 1 cm : 10 m. What is the width of the new stage?
Answer:
50mStep-by-step explanation:
Given the dimension
Length of the rectangle = 8cm
Width = 5cm
Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m
If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;
5 * 10 = 50m
Hence the width of the new stage will be 50 m
Answer:
50m

Step-by-step explanation:
hope this helped and is that iready??
The remainder of 74 divided by 7 is 4.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
When a number is divided by another number, the number which is being divided is the dividend. Divisor is the number which divides the dividend.
Quotient is the value after the division process.
Remainder is the remaining value after the division.
If the dividend is completely a factor of divisor, remainder will be zero.
Otherwise there will be a non zero number as the remainder.
74 is not a multiple of 7.
70 is the multiple of 7 which is closest to 74.
Remainder = 74 - 70 = 4
Hence the remainder is 4.

Alexis opened a savings account with a $120 deposit. Each week she will put $20 into the account. The equation that gives the total amount t in her account is t 120 20w, where w is the number of weeks since she opened the account. How much money will Alexis have in her savings account after 5 weeks?
Answer:
The amount of money Alexis will have in her savings account after 5 weeks is $ 220.
Step-by-step explanation:
The equation that gives the total amount t in her account is t=120+20w, where w is the number of weeks since she opened the account.
To calculate the amount of money Alexis will have in her savings account after 5 weeks, you replace the number of weeks w since she opened the account by 5:
t=120+20*5
Solving, you get:
t=120+100
t=220
The amount of money Alexis will have in her savings account after 5 weeks is $ 220.
