Answer:
x = 7
Step-by-step explanation:
The acute angles in a right triangle are complementary, so we have ...
(7x +5)° +36° = 90°
7x = 49 . . . . . . . . . . . . divide by °, subtract 41
x = 7 . . . . . . . . . . divide by 7
A cone has a height of 20 meters and a radius of 10 meters. What is its volume?
Use a 3.14 and round your answer to the nearest hundredth.
Volume of a Cylinder: In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.
The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.Step-by-step explanation:

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compounded monthly for 5 years.
Answer:
$367.17
Step-by-step explanation:
we are find the cost of the car after 5 years
Using the compound interest formula;
A = P(1+r/n)^nt
Given
Principal P = $300
rate r = 5.2% = 0.052
Time t = 5years
Time of compounding n = 1/12 (monthly)
Substitute into the formula
A = 300(1+0.052(12))^5(1/12)
A = 300(1+0.624)^0.4167
A = 300(1.624)^0.4167
A = 300(1.2239)
A = 367.17
hence the amount of the car after 5years is $367.17
write the inequality in words 1/3n-10>22
Answer:
10 is subtracted from a third of a number is greater than 22
Step-by-step explanation:
1/3n-10>22
you subtract 10 from 1/3n
1/3 - 10 is greater than 22
so:
10 is subtracted from a third of a number is greater than 22
Luke wants to send 21 parcels by the Express service.

(Inequalities) what do you have to do when multiplying or dividing by a negative number?
Answer:
When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.
Step-by-step explanation:
You are welcome.
And I hope this helps. :)
Answer:
Step-by-step explanation:
If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality. Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive. Generally you can either multiply every term in the given inequality by -1 or divide every term by -1. In both cases you must change the direction of the inequality sign.
Example: Given -3x > 2 + 5y, solve for x. To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right. We must reverse the direction of the inequality sign, so the final answer is x < -2/3 - (5/3)y.

Answer:
3.9x+0.8y
Step-by-step explanation:
4x−5.2y+6y+7.9x−8x
Combine −5.2y and 6y to get 0.8y.
4x+0.8y+7.9x−8x
Combine 4x and 7.9x to get 11.9x.
11.9x+0.8y−8x
Combine 11.9x and −8x to get 3.9x.
3.9x+0.8y
It can also be converted to fraction form:
[tex]\frac{4y}{5}+\frac{39x}{10} = 3.9x+0.8y[/tex]

Answer:
1) 2² + 5² = ?²
2) 6² + ?² = 9²
3) 8² + 16² = ?²
4) 8² + ?² = 10²
Step-by-step explanation:
Because these are all right triangles, we can use the Pythagorean Theorem:
a² + b² = c²
Where c is the hypotenuse, the longest side of the triangle. It can be identified as being across from the right angle of the right triangle.
The legs are the two other sides of the triangle and they are interchangeable when placed in the Pythagorean Theorem.

Answer:

Step-by-step explanation:
Hey There!
So the rule about interior angles of a trapezoid
is that the angles that lie on the segments that are not parallel are supplements
so essentially what I'm saying is that angle R and angle U are supplementary angles so to find x we do
180=15x+8+7x-4
step 1 combine like terms
15+7=22
8-4=4
now we have
180=22x+4
step 2 subtract 4 from each side
180-4=176
now we have
176=22x
step 3 divide each side by 22
176/22=8
so x=8
now we plug in 8 to 15x+8
8x15=120
120+8=128
so we can conclude that angle R = 128
Solve the equation.
