the area of the surface of this design is 31 in long
Answer:
392 inches²
Step-by-step explanation:
10 inches × 6 inches = 60 inches²
60 inches² × 2 = 120 inches²
----------------------------------------------------------------------------------------------------------
(6 inches + 4 inches) × 6 inches = 10 inches × 6 inches = 60 inches²
60 inches² × 2 = 120 inches²
----------------------------------------------------------------------------------------------------------
(10 inches × 6 inches) + (4 inches × 4 inches) = 60 inches² + 16 inches² = 76 inches²
76 inches² × 2 = 152 inches²
----------------------------------------------------------------------------------------------------------
Add them all together ~
120 inches² + 120 inches² + 152 inches² = 392 inches²
A rectangular room measures 12 feet by 7 feet. Find the cost of installing a strip of wallpaper around the room if the wallpaper costs $ 0.97 foot.
Total costs= $ _____
Find the perimeter of the room, which is the sum of all four sides:
12 + 12 + 7 + 7 = 38 feet.
The cost would be 38 ft x 0.97 per foot = $36.86

Evaluate the following function when x = 2: f(x) =x^2-x+2
Answer: 4
Step-by-step explanation:
First you do the exponent because of "order of operation", which in this case is 2 to the 2nd power or 2 squared. Then you substract the answer you got by doing 2 squared, which is supposed to give you an answer of 4 which then gets substracted by 2, which leads to the answer being 2 and then you add 2 + 2 and the final answer is 4

Question 1: What is the measure of ZD?
A: 107
B: 37
C: 64
D: 73
Question 2
What is the measure of ZE?
A: 43
B: 73
C: 116
D: 64
What is the measure of ZG?
A: 43
B: 73
C: 137
D: 116
Answer:
C, A, C
Step-by-step explanation:
1) Angle D corresponds to angle A, so since corresponding angles of similar triangles are congruent, it measures 64 degrees.
2) Angle E corresponds to angle B. To find the measure of angle B, we can start by using the fact that angles F and C correspond. This means that in triangle ABC, we have angles with measures of 64 degrees, 73 degrees, and angle B. It follows that angle B, and thus angle E, measures 43 degrees.
3) By the exterior angle theorem, the measure of angle G is equal to the measure of angles D and F combined. The measure of angle D is 64 degrees, and the measure of angle F is 73 degrees, so angle G measures 137 degrees.

In one day, Annie traveled 5 times the sum of the number of hours Brian traveled and 2. Together they traveled 20 hours. Find the number of hours each person traveled.
Answer:
Annie- 17 hours, Brian- 3 hoursStep-by-step explanation:
Let the number of hours Annie travelled be a, and same of Brian be b
Then we have
a + b = 20a = 5b + 2Substituting a in the first equation
5b + 2 + b = 206b = 20 - 26b = 18b = 3Then finding a
a = 20 - 3 = 17So the answer is:
Annie- 17 hours, Brian- 3 hoursUse the figure below to match the type of angles with the correct type of angles.

1) Match the descriptions with the properties.
If you multiply or divide both sides of an inequality by a negative number, you must change the direction of the inequality symbol.
If you divide the terms of one side of an inequality by a positive number, you must divide the terms of the other side of the inequality by the same number for the inequality to remain true.
If you add a value to one side of an inequality, you must add the same value to the other side of the inequality for the inequality to remain true.
Addition Property of Inequality
Division Property of Inequality
Inequality Property of Multiplication or Division by a Negative Number
Multiplication Property of Inequality
Subtraction Property of Inequality
Answer:
B. If both sides of an inequality are multiplied or divided by a negative number, the direction of the inequality symbol must be reversed.

8. Which is the better buy: 200 g of coffee beans at $3.85 or 1 pound at $960?
How do I solve it
Answer:
200g of coffee beans
Step-by-step explanation: 453.592g = 1 pound going by 200 per $3.85 that would be way better than $960
Answer:
200 grams
Step-by-step explanation:
1 pound is 453.592 grams and 200 grams is 0.440925 of a pound. If you paid $3.85 for 200 grams you'd pay a little over $7.70 to get a pound. But if you paid $960 for a pound you'd have to pay a lot more money. So 200 grams of coffee beans is the better buy.
A quantity with an initial value of 8600 grows exponentially at a rate of 20% every 2 minutes. What is the value of the quantity after 67 minutes, to the nearest hundredth?
Answer:

What is the the independent quantity and the dependent quantity.
If Sam buys the pair of shoes for $64, he will have to pay a sales tax of $5. 28
Hey there!
Total = Price+ Sale s tax
=> $64 + $5. 28
=> $69.28
Therefore, Total cost is $69.28
The independent quantity would be the cost of the shoes ($64) and the dependent quantity would be the amount of sales tax ($5.28).
What is the independent and dependent variable?In mathematics, independent and dependent variables are values that vary in relation to one another. The dependent variable is dependent on the independent variable, which means that if the value of the independent variable changes, so will the dependent variable.
In this scenario, the independent quantity would be the cost of the shoes ($64) and the dependent quantity would be the amount of sales tax ($5.28).
The cost of the shoes is the independent variable because it is the value that is being used to calculate the amount of sales tax, which is the dependent variable.
The amount of sales tax depends on the cost of the shoes, hence the name "dependent variable."

Solve the equation for y.
(15y+24)/a =f PLEASE DO NOT HELP ME IF YOU DO NOT KNOW WHAT YOU ARE DOING!! Everyone on this app who has helped me have been getting me wrong on all my work.
Answer:
y = [tex]\frac{fa - 24}{15}[/tex]
Step-by-step explanation:
[tex]\frac{15y + 24}{a}[/tex] = f
multiply both sides by a
(15y + 24) = fa
the parenthesis can be removed
15y + 24 = fa
subtract 24 from both sides
15y = fa - 24
divide both sides by 15
y = [tex]\frac{fa - 24}{15}[/tex]

The longer side of a rectangle has a length of 10. the rectangle is rotated around line k at this side. rectangle abcd has a perimeter of 32 units and will be rotated about line k. what is the three-dimensional solid created? what is the radius of a base?
The radius of the base after rotating the rectangle will be 5
What is the radius of the base?Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created is a cylinder.
Let's calculate its radius from the perimeter;
[tex]2p=32[/tex]
[tex]2(b+h)=32[/tex]
[tex]b+h=16[/tex]
[tex]b=16-h[/tex]
Also, [tex]bh=60[/tex]
Thus;
[tex]h(16-h)=60[/tex]
[tex]h^2-16h+60=0[/tex]
Using the online quadratic formula, we have h = 6
Thus; b = 16 - 6 = 10
Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 10/2 = 5.
Thus the radius of the base after rotating the rectangle will be 5
