the ratio of the measure of angle A to the measure of angle B is 3:2. find the measure of angle A.​

Answer:

h=-18

Step-by-step explanation:

Here you go mate

Step 1

55 – -26h = -413  Question

Step 2

55 – -26h = -413

26h+55=-413

Step 3

26h+55=-413  Subtract 55

26h=-468

Step 4

26h=-468  Divide sides by 26

Answer

-18

Answer:

70

Step-by-step explanation:

the sum of the three is 180, so c is 60, a is 70, and b is 50.

Answer:

.08

Step-by-step explanation:

Since percentages are out of 100, 8% would be 8/100. You can just convert that to a decimal, so it'd be .08, (eight hundredths) !

i hope this helped! Have a great day :)

Answer:

When we have a set of N elements, the number of combinations of K elements (such that N ≤ K) from these N elements is:

[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]

Then if we have 8 different types of carpet, and we want to see how many different samples of 3 types we can choose, we just need to replace N by 8, and K by 3 in the above equation:

[tex]C(8, 3) = \frac{8!}{(8 - 3)!*3!} = \frac{8!}{5!*3!} = \frac{8*7*6}{3*2} = 56[/tex]

So there are 56 different samples.

Now we can do the same, but this time we want to use 5 types of carpet, then we will have K = 5.

[tex]C(8, 5) = \frac{8!}{(8 - 5)!*5!} = \frac{8!}{3!*5!} = 56[/tex]

Again, we have 56 different samples.

Answer: 39°

Step-by-step explanation:

This is a right triangle, meaning one of the angles is a 90° angle. Angle CBA in this case is the 90° angle. In order to figure out the measure of ABD, you subtract the measure of CBA by the measure of CBD, which is 51°.

90 - 51 = 39

Thus, the measure of ABD is 39°

1 1/4 = 1.25

3/8 = .375

1.25 - .375 = .875

plz mark brainliest! :)

Hi there!

Difference:

[tex]\frac{7}{8}[/tex]

1.Convert each fraction terms into a similar denominator:

[tex]1\frac{1}{4}=1\frac{2}{8}[/tex]

[tex]\frac{3}{8}=\frac{3}{8}[/tex]

2.Simplify term into mixed numbers:

[tex]1\frac{2}{8}=8+2=10:\frac{10}{8}=\frac{5}{4}[/tex]

3.Subtract the terms:

[tex]\frac{10}{8}-\frac{3}{8}=\frac{7}{8}[/tex]

Therefore, the difference in length between 1 1/4 and 3/8 is 7/8...

Answer:

2.5 hours

Step-by-step explanation:

We are given that

Original height of candle=5 in

Every hour candle loses =8% of 5 in=0.4

According to question

[tex]5-0.4x>4[/tex]

Subtract 4 from both sides we get

[tex]5-4-0.4x>0[/tex]

[tex]1-0.4x>0[/tex]

[tex]-0.4x>-1[/tex]

[tex]0.4x<1[/tex]

Divide by 0.4 on both sides

[tex]x<\frac{1}{0.4}[/tex]

[tex]x<2.5[/tex]

x=2.5 hours

Until the candle has been burning for at least 2.5 hours, the height of her candle will be more than four inches.

Answer:

22.5 feet.

Step-by-step explanation:

Volume = length * height + width, so:

3510 = 13 * 12 * width

So width = 3510 / (13*12)

= 22.5 feet.

Answer: c = 1.05p

Step-by-step explanation:

Price of the hat = p

Percentage increase in the price of the hat = 5%

The equation to calculate the increase of the total cost, c, of the hat will be:

c = p + (5% × p)

= p + (5/100 × p)

= p + (0.05 × p)

= p + 0.05p

c = 1.05p

Answer:

B) Yes

Step-by-step explanation:

2=4(1)-2

2=4-2

Yes.

2=10(1)-8

2=10-8

Yes.

Answer:

x =18

Step-by-step explanation:

[tex]\frac{x}{6} = 3[/tex]

x = 3 x 6

x = 18

Verify:

[tex]\frac{18}{6} =3[/tex]  (Correct)

Given:

The figure of a right angle triangle.

[tex]a=b[/tex]

Hypotenuse = [tex]9\sqrt{2}[/tex] in.

To find:

The missing lengths of the sides.

Solution:

In the given right angle triangle both legs a and b are equal, and hypotenuse is [tex]9\sqrt{2}[/tex] in.

Using Pythagoras theorem, we get

[tex]Hyponteuse^2=Base^2+Perpendicular^2[/tex]

[tex](9\sqrt{2})^2=(a)^2+(b)^2[/tex]

[tex]81(2)=(a)^2+(a)^2[/tex]                    [tex][\because a=b][/tex]

[tex]81(2)=2(a)^2[/tex]

Divide both sides by 2.

[tex]81=(a)^2[/tex]

Taking square root on both sides.

[tex]\pm \sqrt{81}=a[/tex]

[tex]\pm 9=a[/tex]

Side cannot be negative. So,

[tex]9=a[/tex]

Thus, the missing side lengths are a=9 in and b=9 in.

Therefore, the correct option is C.

Answer:

B

Step-by-step explanation:

when the arrow is pointing toward the left side that means less than side. When the arrow is pointing towards the right side that means greater than.

Answer:

B, because that symbol means at least so you would go to the negative side which is on the left it has to start from 4 which is correct and this means negative: - The 0 is the origin so from the origin to the left side is negative from the origin to the right side is positive you want to look for negative because it's negative 4.

Answer:

nine is the area I think

Step-by-step explanation:

base times height is width

Answer:

27 in. ^2

Step-by-step explanation:

Ok. Let's start by reflecting on what the definition of lateral area is. In this case, it's all the faces except the 2 equilateral triangle faces. So, let's find the rectangular faces. Length for all of them is 9, width for all of them is 1. So, area is 9 for all 3 lateral faces. 3*9=27.
