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:

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)

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.

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(8a+5)

To factor means to find a number that can divide all the terms in the expression and leave whole number quotients. The factor is written outside the bracket while the quotients are written inside the bracket. In the question, 2 can divide both 16a and 10 giving 8a and 5. This is how the answer was obtained.

Step-by-step explanation:

Answer:

2(8a + 3)

Step-by-step explanation:

bring out the common factors

which is two

2(8a + 3)

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

So what am I answering here?

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°

Answer:

80 porque parece el más

Step-by-step explanation:

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:

Step-by-step explanation:

A I believe sorry if wrong

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:

The slope of the line is -3/1

Step-by-step explanation:

Using the rise over run method I calculated that the slope is -3/1 because every block that the line goes over it goes 3 down.

Answer:

Slope of the Line = 3.

Answer:

92 percent

Step-by-step explanation:

Answer:

92% of balloons filled did not pop.

Step-by-step explanation:

2 / 25 balloons is the fraction of balloons that do pop, and we want the percentage that don't pop.

To start off with, we will get the fraction of balloons that don't pop - 23 / 25.

We will then convert this fraction to a decimal by dividing the fraction:

23 divided by 25 = 0.92

Now, to convert this to a percentage, we just multiply by 100.

0.92 x 100 = 92%

Therefore the answer is 92% of balloons filled did not pop.

Answer:

[tex]1\frac{3}{5}[/tex] or 1.4 as a decimal

Answer:

1) 117

2) 51

3) congruent

4) to each other

Step-by-step explanation:

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 :)

Step-by-step explanation: it not easy tho

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.
