Answer:

6.25 x 10^2

Step-by-step explain:

625 could be 6.25 and you move the decimal 2 times to the right.

Answer:

Step-by-step explanation:

bc + ad = b

bc + ad/bc = b/bc

ad = b/bc

ad/d = b/bc + d

a = b/bc+d

Answer:

9a)   6 miles

9b)  12:20

Step-by-step explanation:

for first question, use the distance formula:  distance = rate · time

d = 2 x 3

d = 6 miles

for second question, she began walking home at 11:05 and it took 1 hour, 15 minutes (15 minutes is 1/4 of 60 minutes)

11:05 + 1 hour = 12:05

12:05 + 15 minutes = 12:20

Answer: B. 9

Step-by-step explanation:

3^4 / 3^2

When dividing deomenators, it is the same as subtracting the exponents.

3^4 / 3^2 is the same as 3^2 or 3 * 3 which is 9

Answer: -2/3

Step-by-step explanation:

If you want to find the slope of something, the quick way is to use [tex]\frac{rise}{run}[/tex].

In this situation, the “rise” (change in y axis) is -2 because it’s going down and the “run” (change in x axis) is 3. Therefore, it’s -2/3.

The formula to find slope is:

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex]

(I think, if I memorized it correctly)

Answer:

B: (2, -1)

Complete Question

Write a rational equation that relates the desired percentage p, to the amount A of a 30% solution that needs to be added to 1 liter of 10% acid solution to make a blend that is p% acid, where 0<p<100 . What is a reasonable restriction on the set of possible values of ? Explain your answer.

Answer:

100(0.1 + 0.3A)= (1 + A) P

Step-by-step explanation:

A of a 30% solution that needs to be added to 1 liter of 10% acid solution to make a blend that is p% acid,

Hence,

10% of 1 + 30% of A = p%(1 + A)

0.10 + 0.3A = (p/100)(1 + A)

Divide both sides by 1 + A

0.1 + 0.3A/ 1 + A = p/100

Cross Multiply

100(0.1 + 0.3A) = 1 + A(p)

From the above calculation, we can see that, the blend that would be formed is not lower than 10% or greater than 30%

10% < p< 30%

Answer:

Step-by-step explanation:

Answer:

√10 = 3.162

Step-by-step explanation:

The square-root of 10 is;

√10 = 3.162

A number divided by 5 has its last digit as 0 or 5

In this case 25/5 = 5   and the √25 = 5

Answer: The cost for 42kg is $210

Step-by-step explanation:

375/75=$5 for 1kg

$5*42=$210

Answer:

The y-value sequence on 1  linear. The x-value sequence on 1 is also linear.

The y- value sequence on 2 is linear. The x-value sequence on 2 is also linear.

The y-value sequence on 3 is linear. However I now think you are referring to the domain and range also linear graphs and non linear graphs, maybe I've confused you.

Step-by-step explanation:

So the difference between an exponential function and a linear function is whether it is arithmetic sequence or geometric sequence or just another sequence.

arithmetic is if the numbers are added by the common difference.

geometric is if the numbers are multiplied by the common ratio.

Step-by-step explanation:

Answer:

C. 50ft

Step-by-step explanation:

Perimeter is the outside and in perimeter you add

The length is 15ft

The width is 10ft

There are 4 sides so you want to add the length and width 2 times

L = 15 + 15 = 30

W = 10 + 10 = 20

Then add it all together

30 + 20 = 50

Hope this helps dude

Given:

[tex]4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{12}[/tex]

To find:

The value of given expression.

Solution:

We have,

[tex]4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{12}[/tex]

It can be written as

[tex]=4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{4\times 3}[/tex]

[tex]=4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+2\sqrt{3}[/tex]

Using distributive property, we get

[tex]=4\sqrt{7}-2(2\sqrt{7})-2(\sqrt{3})+2\sqrt{3}[/tex]

[tex]=4\sqrt{7}-4\sqrt{7}-2\sqrt{3}+2\sqrt{3}[/tex]

[tex]=0[/tex]

Therefore, the value of given expression is 0.

Answer:

  (d)  Reflexive Property of ≅; SSS

Step-by-step explanation:

There are no angles involved in the proof, so the SAS claims do not apply.

__

The symmetric property says ...

  if A ≅ B, then B ≅ A

The reflexive property says ...

  A ≅ A

In this case, the reflexive property is the one being invoked in the statement ...

  AC ≅ AC

That, together with the claims of line 3 concludes the claim that all three sides are congruent to their corresponding counterparts. Hence the SSS postulate applies.

12(15)>135+4.50(15)

180>135+67.50

180>202.50

False. They will not make a profit since the cost is 202.50 versus the selling price 180
