The are of a shaded region is 118 ft squared. Which equation can be- used to find the value of X, in feet?
Answers
Answer:
[tex]x^2+ 18x -130=0[/tex]
Step-by-step explanation:
Given
See attachment for diagram
Required
The equation to find x
First, calculate the area of the big rectangle using:
[tex]Area = Length * Width[/tex]
So:
[tex]A_1 = (x + 6) * (3x - 2)[/tex]
The smaller rectangle
[tex]A_2 = (x - 1) * (2x)[/tex]
The difference between this areas give the area of the shaded region.
So:
[tex]A_1 - A_1 = 118[/tex]
[tex](x+6)*(3x-2) - (x-1)*2x = 118[/tex]
Open brackets
[tex]3x^2 - 2x + 18x -12 -2x^2 +2x = 118[/tex]
Collect like terms
[tex]3x^2 -2x^2- 2x +2x+ 18x -12 - 118=0[/tex]
[tex]x^2+ 18x -130=0[/tex]
The above equation can be used to solve for x

You rent an apartment that costs $1800 per month during the first year, but the rent
is set to go up 11.5% per year.
What would be the rent of the apartment during the
10th
year of living in the apartment? Round to the nearest tenth (if necessary).
Answers
Answer:
Rent in 10th year = $5345.90
Step-by-step explanation:
Rent of apartment during first year = $1800 per month
But growth in rent with 11.5% per year will be represented by the exponential function,
Rent in 't'th year = [tex]\text{Initial rent}(1+\frac{\text{Growth rate}}{100})^{\text{time}}[/tex]
= [tex]1800(1+\frac{11.5}{100})^t[/tex]
= [tex]1800(1.115)^t[/tex]
Therefore, rent during 10th year will be,
Rent in 10th year = [tex]1800(1.115)^{10}[/tex]
= $5345.90

A fish was at the river-bed at a certain time. After 5 minutes, the water level of the river rose
up 2.4 cm and the water level of the river rose up again 3½cm after 4 minutes. The moment, the fish was at 14.6 cm from the river-bed and 162 cm below water level of the river.

Let the original water level is x.
Use below equation to find its value:
x + 2.4 + 3 1/2 = 162 + 14.6x + 2.4 + 3.5 = 176.6x + 5.9 = 176.6x = 176.6 - 5.9x = 170.7 cmFind x if y =(x - 4) - 25 and y=0

A water container in the shape of a cone has a height of 5 inches and a diameter of 3.5 inches.
Enter an equation in the first blank box and a number in the second blank box to complete the statements about the
water container ___.
A. The formula to calculate the container's volume, V, with the given measurements is
B. The container can hold approximately ___ cubic inches of water. Round your answer to the nearest hundreth.
Answers
Answer
A. The formula to calculate the container's volume, V, with the given measurements is ⅓ π(1.25²)5.
B. The container can hold approximately 8.177 cubic inches of water. Round your answer to the nearest hundredth.
Step-by-Step Explanation
A. The formula to calculate any cone's volume is ⅓ πr²h. Replace the variables with the actual values of the cone. r stands for the cone base's radius, or half of the diameter. Because the diameter is 3.5, the radius is 1.25, or half of it. The h stands for the height of the cone. Now we can plug in the values. Our answer for this part is ⅓ π(1.25²)5.
B. Now to solve our equation. [tex]1.25^2[/tex] is equal to 1.5625. Now, multiply by the height. 1.5625 x 5 is equal to 7.8125. We now multiply by [tex]\pi[/tex]. We'll use 3.14 to shorten the answer a bit. Multiply 7.8125 by 3.14 and you'll get 24.53125. Last but not least, divide this by 3 (or multiply by [tex]\frac{1}{3}[/tex]). [tex]\frac{24.53125}{3}[/tex] = 8.1770833333... We now must round this to the nearest hundredth. This makes our final answer 8.177 [tex]in^3[/tex].

What is the value of 2x^2+6x-9 when x = 3
Answers
Answer:
45
Step-by-step explanation:
We have the equation 2x² + 6x + 9 and are asked to find the value when x =3.
To solve this, all we need to do is substitute all variables with "x" to 3. Then do the properties :
2x² + 6x + 9
2(3)² + 6(3) + 9
Do exponents first :
2(9) + 6(3) + 9
Now multiply the numbers with parenthesis next to them :
18 + 18 + 9
Add to get the answer :
45
Answer:
27
Step-by-step explanation:
We have the equation:
2x^2+6x-9
If x = 3, we can substitute 3 in for the x values.
We get the equation:
2([tex]3^{2}[/tex]) + 6(3) - 9
Using PEMDAS:
First, evaluate the power.
3^2 = 9
Then, multiply the numbers.
2 x 9 + 6 x 3 - 9
We get:
18 + 18 - 9
Simplify.
18 + 18 = 36
36 - 9 = 27

A circle has a circumference of 37 millimeters. What is the circle's
radius? Use 3.14 for pi and round your answer to the nearest tenth.
Answers
Answer:
