what is the volume of the composite figure page 512 chapter 11 4
IM just a little bit slow
Answer:
71°
Step-by-step explanation:
31-3x+19x-5=90
16x=90-26
16x=64
x=4
m<R=19x-5 = 19(4)-5 = 76-5 = 71
Answer:
x = 4
∠R = 71°
Step-by-step explanation:
COMPLEMENTARY ANGLES: TWO ANGLES WITH A SUM OF 90°.
[tex]31 - 3x + 19x - 5 = 90[/tex]
To make this problem easier to solve, we can combine like terms.
[tex]26 + 16x = 90.[/tex]
Now, we can proceed.
First, subtract 26 from 26 and 90.
[tex]26 - 26 = 0.[/tex] (cancels itself out).
[tex]90 - 26 = 64.\\[/tex]
Now, we are left with 16x = 64.
Lastly, we divide the number in front of the variable by the answer.
[tex]64/16 = 4[/tex]
Therefore, the value of x is 4.
-------------------------------------------------------------------------------------------------------------
Now that we have the value of x, we can use this value to replace the variable (x).
[tex]19x - 5[/tex]
[tex]19 * 4 - 5 = 71.[/tex]
Therefore, the value of ∠R is 71°.

find 3/5% of $90,000
Solve for c.
a(c+b) = d
Answer:
c = (d/a) - b
Step-by-step explanation:
a(c + b) = d
Divide both sides by a
c + b = d/a
subtract b from both sides
c = (d/a) - b
if 3/5 of a number is 2 more than 2/3 of the same number, then what is the value if the square of the number
9514 1404 393
Answer:
900
Step-by-step explanation:
Let x represent the number. The given relationship is ...
(3/5)x = 2 +(2/3)x
-2 = 1/15x . . . . . . . . subtract 2+3/5x from both sides
-30 = x . . . . . . . . . . multiply by 15
Then the square of the number is ...
x² = (-30)² = 900
Two students in the same Spanish class, Perry and Dakota, plan to get together after school
to make vocabulary flashcards. Perry started on the project yesterday and has already made
5 flashcards. Dakota hasn't started yet. Since Perry makes 4 flashcards per minute and
Dakota makes 5 flashcards per minute, Dakota will soon have the same number of
flashcards. How many flashcards will each student have at that point?
Write a system of equations, graph them, and type the solution.
Answer:
Dakota=20 perry=25 together= 45
Step-by-step explanation:
First step, remember to keep 5
second step, if they are find keep multiplying until they both meet the same number which is 20, but they both have 20. But Perry will have 25 since he started a day before

(1, 2)
Step-by-step explanation:
PR and QR are vertical and horizontal line segments, respectively. Then ΔQPR is a right triangle, and segment PQ is the hypotenuse. As such, segment PQ is also a diameter of the circumcircle, and its midpoint is the circumcenter.
Circumcenter = (P+Q)/2 = ((4, 0) +(-2, 4))/2 = (2, 4)/2
Circumcenter = (1, 2)
What would be x please help me
Answer:
[tex]18.83[/tex]
Step-by-step explanation:
For right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.
Therefore, we have the equation:
[tex]\tan 33^{\circ}=\frac{x}{29},\\x=29\tan 33^{\circ}\approx \boxed{18.83}[/tex]

============================================
Explanation
Consider this: You have 7 donuts and 4 friends you want to split the donuts with. The question is, how many donuts does each of your friends get?
The number 7 isn't a multiple of 4, meaning 7/4 won't result in a whole number. If you had one more donut, then 8/4 = 2 is a whole number. So that must mean everyone only gets one whole donut plus some leftover amount.
If those 4 friends get 1 whole donut each, then 4*1 = 4 donuts are passed out and 7-4 = 3 are left over. The "1" forms the whole part of the mixed number, while the '3' is the numerator of the fraction. The denominator stays the same at 4.
So we go from the improper fraction 7/4 to the mixed number 1 & 3/4. Each person gets 1 whole donut and then 3/4 of a whole donut
------------
We can write the mixed number 1 & 3/4 as [tex]1 \frac{3}{4}[/tex]. Keep in mind that this expression does not mean 1 times 3/4. Instead, it really is saying 1 + (3/4).

A family on vacation drove a total round-trip distance of 735.75 miles. They traveled
for 7 hours in one direction and 6.5 hours on the return trip. What was their average
speed for the entire trip?
Answer:
speed = 54.5 miles/hr
Step-by-step explanation:
speed = distance/time
distaance = 735.75
time = 7 + 6.5 = 13.5
speed = 735.75 / 13.5
speed = 54.5 miles/hr
Determine the lengths of both missing sides

The Skate Center charges a $50 flat fee kick-back party rental and $5.50 for each person who attends. Your parents gave you no more than $300 to spend on the party. How many people can you invite to the party without going over budget? I NEED THE ANSWER QUICK!
Answer: 45 people
Step-by-step explanation:
Data: $50 to rent the Skate Center
$5.50 for each person who attends
Limit of spending: $300
How many people can attend=x
Step one, Make the equation
$5.50x+$50=$300
Reason: Since we know that amount of people(x) multiplied by $5.50 added to $50 will get us $300, we can make an equation from that. The equation will make the problem simpler to solve.
Step two, Start isolating x by subtracting $50 on both sides
$5.50x+$50-50=$300-50=$5.50x=$250
Reason: Since we have to find x, we have to isolate it. The first step in doing that is subtracting $50 by 50 to get rid of it. However, since what you do to one side, you do to the other, you have to subtract $300 by 50 to get $250.
Step three, Divide by 5.50 on both sides
$5.50x/5.50=$250/5.50=x=45.454545454-
Reason: Since we have to isolate x and 5..50 is being multiplied by x, you have to divide it by 5.50 to get rid of 5.50. What you do to one side, you do to the other so you divide 250/5.50 to get 45.4545454545-.
Since this is a irl problem, you have to round it to 45 people
Answer: 45 people

The given expression gives [x] as 2.7.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following equation -
10(x + 10) = 127
Given is -
10(x + 10) = 127
x + 10 = 12.7
x = 12.7 - 10
x = 2.7
Therefore, the given expression gives [x] as 2.7.

Find the derivative of y=2x^2-3x+1 and the slope of the curve at the point where x=3
The slope of the tangent line to y(x) at any given x is equal to the derivative dy/dx at that point. Differentiate to get
[tex]\dfrac{\mathrm dy}{\mathrm dx}=\boxed{4x-3}[/tex]
and evaluate it at x = 3 to get the slope, 4•3 - 3 = 9.
Which expression has a value of 7/12?
1. 2 1/12 + 5 1/12
2. 6/8 + 1/4
3. 1/3 + 1/4
4. 7/8 + 4
Answer: 3. 1/3 + 1/4
Step-by-step explanation:
1/3 = 4/12
1/4 = 3/12
4/12 + 3/12 = 7/12
The graph of a proportional relationship and an equation are shown.
What is the greater unit rate?
Answer:
Graph has the greater unit rate.
Step-by-step explanation:
From the graph attached,
Since, graph shows the proportional relationship,
y ∝ x
y = kx
Here, k = unit rate
If the line given in the graph passes through (0.2, 1.5)
Slope of this line will be,
k = [tex]\frac{1.5}{0.2}[/tex]
k = 7.5
Therefore, unit rate = 7.5
Equation of the line given in the question is,
[tex]y=\frac{11}{2}x+3[/tex]
Comparing this equation with the y-intercept form of the equation,
[tex]y=mx+b[/tex]
Slope of this line 'm' = [tex]\frac{11}{2}[/tex]
= 5.5
Unit rate of the given equation = 5.5
Therefore, graph has the greater unit rate.
