Step-by-step explanation:

Sorry for not giving the exact answer the question is worded badly..

Answer: 32

Step-by-step explanation:

16 + 16. if you break it down, you can get 8 x 4. so if you count 8, 16, 24, (32) is your answer.

The + 4 translates the parent function 4 units to the left ( not up).

The linear function for the depth of water after t hours is given by:

[tex]d(t) = 17 - 1.5t[/tex]

The format of a linear function is given as follows:

[tex]d(t) = d(0) - at[/tex]

In which:

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:

[tex]d(t) = d(0) - 1.5t[/tex]

The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).

[tex]d(t) = d(0) - 1.5t[/tex]

[tex]8 = d(0) - 1.5(6)[/tex]

[tex]d(0) = 17[/tex]

Then

[tex]d(t) = 17 - 1.5t[/tex]

The question is an illustration of arithmetic operations.

The integer that represents the vertical rise is 76

Upward movements are represented with positive, while downward movements are represented with negative.

So, the given parameters are:

[tex]Up = 100m[/tex]

[tex]Down = -72m[/tex]

[tex]Up= 48m[/tex]

The vertical rise is:

[tex]Rise = Up_1 + Down + Up_2[/tex]

So, we have:

[tex]Rise = 100m -72m +48m[/tex]

[tex]Rise = 76m[/tex]

Hence, the integer that represents the vertical rise is 76

Answer:

Step-by-step explanation:

3 = 2/3 m

m = 9/2

by the matrix property of associative: (A+B)+C = A+(B+C)

H = [-2  8  -1]

m x H = 9/2 x [-2  8  1] = [-9  36  -9/2]

10(x + 4)

Step-by-step explanation:

Simplify :

[12(x + 3) - 4] - 2(x - 1) + 6

= [12x + 36 - 4] - 2x + 2 + 6

= 12x - 2x + 36 - 4 + 2 + 6

= 10x + 32 + 8

= 10x + 40

= 10(x + 4)

Answer:

175%

Step-by-step explanation:

1. To find how much a percent of a number is, we'd just have to multiply the percent by the number. However, in this case, we're missing the percentage.

2. To find that percentage, we can write an equation of [tex]\frac{x}{100} * 4 = 7[/tex] because "of 4" means to multiply by 4, and "is 7" means that the product is 7.

3. Now, let's solve our equation.

Step 1: Simplify both sides of the equation.

Step 2: Multiply both sides by 25.

Step 3: Check to see if solution is correct.

Therefore, the answer is 175%.

It is B.

Answer:

The answer is 8$- Took the test

Step-by-step explanation:

Answer:

You probably already figured it out, but the correct answer is the last one. Subtract 3 from the product of 9 and m

Step-by-step explanation:

Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m

Step-by-step explanation:

Answer:

11/40

Step-by-step explanation:

If your answering in fraction and not in decimal this is how you do it:

1. Get rid of the brackets surrounding -11/10. You do this by multiplying the positive sign (+) by the negative sign (-) in front of 11. Now the rule says that multiplying a positive with a negative always gives you a negative therefore your fraction in the brackets will remain negative while removing the plus sign. Now your problem should look like this: 11/8-11/10.

2. Finding the common multiple of the denominators. You can't just minus the fractions unless the denominators are the same. To do this you first have to find the lowest common multiple (lcm) of denominators 8 and 10. You can list 5 multiples for each to find this or more depending on how many multiples you need to reach the lcm.

8= 8,16,24,32,40,48,etc.

10=10,20,30,40,50,etc.

The lcm for 8 and 10 is 40.

3. Change the fractions to substitute the new value of the denominators in. To do this you have to multiply the fractions. For example, multiply 11/8 by 5/5 to get 55/40(11×5/8×5). Do the same for the second fraction: 11/10×4/4(11×4/10×4) which gives 44/40.

4. Now finally just minus which is just 55/40-44/40 and your answer will be 11/40. Minus the numerators only not the denominators.

Answer:

j = 7

Step-by-step explanation:

First expand the right hand side:

3 = 3(j-6)

3 = 3j - 18

Then we can move 18 to the left hand side and calculate for j.

3 = 3j - 18

21 = 3j

j = 7

Answer:

divide both sides by 3

Answer:

   C    66 2/3%

Step-by-step explanation:

1/3 =  33 1/3%  

1/3 = 33 1/3 ∙ 1/100             % means 1/100

1/3 = 100/3 ∙ 1/100                33 1/3=    (33∙3+1)/3=100/3

1/3 = 100/300                         Reduce

1/3 = 1/3   Check    so  

1/3 = 33 1/3%

Now     2/3=?%

We know that     2/( 3) =  N ∙ 1/100      meaning of percent (%)

                            2/3 = N/100              

                          200 = 3N

                           200/3 = N

                            66.66 =N      

 Therefore      2/3 = 66 2/3  %

Step-by-step explanation:

Divide both the numerator and denominator by 2.

Answer:

x = - 20

Step-by-step explanation:

12x = -8(10 - x)

12x = -80 + 8x

12x - 8x = -80

4x = -80

x = -80/4 = -20

A ratio will just be trying to find whole number versions of these decimals and then compare them side by side (always divide the larger number by the smaller number).

Therefore:

[tex]\frac{0.0000275}{0.000005}=5.5=\frac{5.5}{1}[/tex]

However, this isn't a proper ratio. Generally, ratios are whole numbers. Since it's 5.5, we can easily make this a whole number by multiplying it by 2. Keep in mind though, what we do to one number we do to the other! So:

[tex]\frac{2}{2}(\frac{5.5}{1})=\frac{2*5.5}{2*1}=\frac{11}{2}[/tex], technically this is a better format since it's whole numbers, but it gives you the ratio (11:2) which is a bit tougher to interpret than (5.5:1)

Therefore, the ratio we'll use is 5.5:1 for simplicity's sake:

From this ratio, we can see that the red tablet is 5.5x the size of the white tablet.
