Answer 1

Answer:

8.88

Step-by-step explanation:

With reference angle 42°

hypotenuse (h) = 12

base (b) = x

Now

cos 42° = b / h

0.74 = x / 12

x = 0.74 * 12

x = 8.88

Answer:

82 units

Step-by-step explanation:

There are multiple ways to go about solving this problem (solving by calculating the areas of the individual, smaller shapes), but I recommend solving it by first calculating the area of the entire figure (96 units - 12 * 8 - length * width ((formula for the area of a rectangle)) and then subtracting the area of the missing part from this value.Assume the opposite sides are equal in value (see picture for work) and subtract the given values (4 and 5) from 8 and 12 to get the measurements to find the triangle (the missing part).You get 7 and 4 and now you use the formula for the area of a triangle to get the area. (7*4)/2, which gives you 14 units.Subtract 14 (area of missing value) from 96 (area of total value) to get your final answer, 82 units!

Answers

Answer: C) Yes, Alternate Exterior Angles Converse

The two red angles are on the outside of the lines a and b, so they are considered exterior. They alternate on either side of the transversal line. So we consider those red angles to be alternate exterior angles. We'll use the alternate exterior angles converse to prove the lines parallel. That converse states: "If alternate exterior angles are congruent, then the lines are parallel".

Triangle ABC was reflected over line m, then dilated by a scale factor between 0 and 1. Which diagram illustrates these transformations?

Answers

The transformation is better described by: Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime

What is transformation?

In mathematics, transformation is manipulating a figure on a plane or coordinate system.

In this case the manipulation involves reflection and scaling to a factor between 0 and 1

scaling to factor 0 means the triangle disappeared

scaling to factor 1 means the triangle remained same size

factors between 0 and 1 means reduction of size.

since the transformation did not rotate the triangle it makes the first option the correct answer

Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer. What was the total amount of money Daniel found?

Answers

Answer:

303 cents.

Step-by-step explanation:

Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer

We know that, dollar is equal to 100 cents

2 dollars = 200 cents

It means, Daniel found 9 cents in his backpack, 89 cents in the couch, and 200 cents and 5 cents in the drawer.

Price = 9+89+200+5

= 303 cents

Hence, Daniel found 303 cents.

If the original quantity is 8 and the new quantity is ,2 what is the percent decrease?

75% of 8 is 6.

8 was decreased by 6 to get 2.

8 was decreased by 75% of its initial value to get 2.

Hope this helped!

Answer:

75%.

Step-by-step explanation:

8 - 100%

2 - x

[tex]\dfrac{8}{100 \%}=\dfrac{2}{x} \\\\x=\dfrac{2 \cdot 100 \%}{8} =25 \%[/tex]

100% - 25% = 75% - the percent decrease.

Robert is pouring wax into cylindrical candle containers. Approximately 226.19 cubic inches of wax fill one candle jar. Which image represents that volume?

A cylinder with height 8 inches and radius 3 inches.
A cylinder with height 5 inches and radius 4 inches.
A cylinder with height 10 inches and radius 2 inches.
A cylinder with height 5 inches and radius 5 inches.

Answers

Answer:

The first choice.

Step-by-step explanation:

The volume must be about 226.19 in^3.

Volume of a cylinder = area of base * height4

= πr^2h = 226.19

r^2 = 226.19 / πh.

Consider the first of the choices:-

When h = 8 , r^2 = 226.19 /8π = 8.9998

So r = 3.00 to nearest hundredth.

So this is the required image.

Step-by-step explanation:

Since we can write 4 as 4/1, that means 4 is the answer. This is because you multiply the top numbers and the bottom numbers, 4x1 is 4, and 1x5 is 5, so that means the answer is 4 since that problem got us 4/5.

Solve. Express your answer as a mixed number. 5 feet= ______ yards Solve. I need an explanation on how to put it as a mixed number and how to solve it.

Answers

Answer: 5 feet= __5/3 0r 1 2/3____ yards

Step-by-step explanation:

Step 11 yard = 3 feet

3 feet = 1 yard

5 feet = 5feet x 1 yard/ 3feet

= 5/3yards

Step 2 To convert 5/3 yards to a mixed fraction,

1. We first Divide the numerator, 5 by the denominator, 3 giving us a whole number and a remainder

5/3 = 1 remainder 2

2.then we write the whole number and put the remainder 2 above the denominator 3 giving us

5/3 = 1 2/3

such that when you multiply the mixed fraction 3 x 1 and add 2 it gives back the improper fraction of 5/3
