Starting with 13 grams of starch, what percentage is left when 6 grams remain? Write your answer to two decimal points.

Answer: 3 gallons

Step-by-step explanation:

From the question, we are informed that Connor is driving on a long road trip and currently has 9 gallons of gas in his car. We are also told that for every hour that he drives, his car uses up 2 gallons of gas.

After driving for 3 hours, his car would have used:

= 3 × 2 gallons

= 6 gallons of gas

Amount of gas left will be:

= 9 gallons - 6 gallons

= 3 gallons

Answer:

They are not similar.

QP would be equal to FP if they were equal but they aren't equal so....yeah

There's a bit of lack of context but I think the question is just asking what variables to put in for Lucy and Howard. There seems to be no need to answer any math problem.

I suggest using the variables x and y or l for Lucy and h for Howard. Remember to use lowercase letters.

If Ali has x cards, then Belinda has 2x cards.

If Ali has x cards, then Charlie has x+5 cards.

2x (Belinda) + x+5 (Charlie) + x (Ali) = 33 (total)

2x + x+5 + x = 33

Now simplify the equation... x+x+5 can be simplified as 2x+5.

2x+5 plus 2x can become 4x+5.

So their total number is 4x+5.

So 4x+5=33.

You want to isolate the variables and numbers.

To remove the 5 from the left side, subtract 5 from both sides.

4x+5-5=4x - 33-5=28

So the equation now is 4x=28

To remove the 4, divide each side by 4.

4x÷4=x - 28÷4=7

So x equals 7, Ali has 7 cards.

[tex]9=7d+8(9-2d)\\9=7d+72-16d\\9=-9d+72\\-72+9=-9d\\-63=-9d\\d=7[/tex]

Also for the 8(9-2d), simplify by multiplying the 8 into the (9-2d) as we get (8*9)-(8*2d) = 72-16d

Therefore, the answer is d = 7 aka C.

Answer:

K = [tex]\frac{4r}{n} -a[/tex] n [tex]\neq 0[/tex]

Step-by-step explanation:

We have our equation [tex]r = \frac{n}{4} (a+K)[/tex] and are looking for K

First we have to switch sides :

[tex]\frac{n}{4} (a+K) = r[/tex]

Since we have a denominator of 4, we multiply both sides by 4 :

[tex]n (a+K) = 4r[/tex]

We then divide both sides by n :

[tex]a+K = \frac{4r}{n} ; n\neq 0[/tex]

Subtract a from both sides :

[tex]K = \frac{4r}{n} -a; n\neq 0[/tex]

Answer:  Answer is in the steps

Step-by-step explanation:

To determine if their are congruent ,find the distance between the points.

In AB  it has the points (-6,-4) and (-1,8)  

Now to find the distance you will have to find the difference between the x and y values then square them to add them and find the square root.

-4 - 8 = -12

-6 - (-1) = -5

12^2 + 5^2 =d^2  where d is the distance so solve for d

144 + 25 = d^2

169 =d^2

d = [tex]\sqrt{169}[/tex]  

d= 13  

So we now the distance of AB is 13  

now we need to find the distance between CD

(2,5)  (14,0)  using these points follow the same steps in the first step to find the distance.

5-0= 5

2 -14 = -12

5^2 + 12^2 = d^2

25 + 144 = d^2

169 =d^2

d = [tex]\sqrt{169}[/tex]  

d= 13

So using the information we can say the segments are congruent because they have the same distances .

See Explanation

Step-by-step explanation:

The question is incomplete has the figure of the triangle is not given.

However, the following steps will guide you.

To solve this question;

you need the lengths of the threes sides of the triangular fields

Represent these lengths with a, b and c

Next;

Sum these lengths together;

This gives the required length of fencing

[tex]Length = a + b + c[/tex]

Take for instance;

[tex]a =4;\ b = 3;\ c = 5[/tex]

The required length of fence would be

[tex]Length = 4 + 3 + 5[/tex]

[tex]Length = 12\ units[/tex]

Apply these steps and you'll get your answer

Answer:

Volume = 36.4 m^3 or 9616.6 gallon

weight = 18025.47 N or 80213.33 lbs

Step-by-step explanation:

The complete question is

A small family home in Tucson, Arizona, has a rooftop area of 1967 square feet, and it is possible to capture rain falling on about 56% of the roof. A typical annual rainfall is about 14 inches. If the family wanted to install a tank to capture the rain for an entire year, without using any of it, what would be the required volume of the tank in m3 and in gallons? How much would the water weigh when the tank was full (in N and in lbf)?

The area of the roof = 1967 ft^2

Area of water to be possibly captured = 56% of 1967 ft^2 = 0.56 x 1967 = 1101.52 ft^2

Rainfall depth = 14 inches = 14/12 ft = 1.167 ft

Volume of water = (area of water) x (depth of water) = 1101.52 ft^2 x 1.167 ft = 1285.47 ft^3

35.315 ft^3 = 1 m^3

1285.47 ft^3 = [tex]x[/tex] m^3

==> 1285.47/35.315 = 36.4 m^3

1 ft^3 = 7.481 gallon

1285.47 ft^3 = [tex]x[/tex] gallon

==> 1285.47 x 7.481 = 9616.6 gallon

Weight of water W = ρv

where ρ is the density of water = 62.4 lbs/ft^3

v is the volume of water = 1285.47 ft^3

substituting values,

W = 62.4 x 1285.47 = 80213.33 lbs

but,

1 lb = 4.45 N

therefore,

80213.33 lbs = 80213.33/4.45 = 18025.47 N

A perfect cube is a number that is the cube of an integer. For example, 125 is a perfect cube since 125 = 5 × 5 × 5= [tex]5^{3}[/tex]. Some examples of perfect cubes are 1, 8, 27, 64, 125, 216, 343, ..

16 does not have a perfect cube, but does have a  perfect square 4×4=16

Answer:

- 11 or - 15

Step-by-step explanation:

Factorise

x² - 13x + 42

Consider the factors of the constant term (+ 42) which sum to give the coefficient of the x- term (- 13)

The factors are - 6 and - 7, since

- 6 × - 7 = + 42 and - 6 - 7 = - 13, thus

x² - 13x + 42 = (x - 6)(x - 7)

compare to (x + A)(x + B)

A = - 6, B = - 7

thus 3A - B = 3(- 6) - (- 7) = - 18 + 7 = - 11

The factors may also be expressed as (x - 7)(x - 6)

with A = - 7 and B = - 6, then

3A - B = 3(- 7) - (- 6) = - 21 + 6 = - 15

Answer:

The actual distance between Phoenix and Fountain Hills is 7.3 miles

Step-by-step explanation:

We note that the scale factor gives the ratio of the map reading to the actual distance reading

The scale factor of the map is 1 inch = 2.5 miles

The distance between Phoenix and Fountain Hills = 2.92 inches on the map

Let the actual distance between Phoenix and Fountain Hills = D, we have;

D/(2.92 inches) = 2.5 miles/inch

Therefore;

D = 2.92 inches ×  2.5 miles/inch = 7.3 miles

D = 7.3 miles

The actual distance between Phoenix and Fountain Hills = D = 7.3 miles.

Answer:

1) x = 0

2) x = 2

Step-by-step explanation:

1)

12 = -4(-6x - 3)

First, we distribute.

12 = 24x + 12

Then, we combine like terms.

12 - 12 = 24x

0 = 24x

Finally, we divide 24 on both sides.

We got 0 = x, or x = 0

-

2)

-20 = -4x - 6x

First, we simplify.

-20 = -10x

Then, we divide -10 on both sides.

We got 2 = x, or x = 2
