Answer:

No, the answer is to divide by 4

Step-by-step explanation:

You're so close, but if you look closely 320/3=106.67. However, 320/4=80. And if you look at the other choices, it applies to all of them. 40/4=10 , 80/4=20 , 120/4=30 , and 160/4=40.

Hope this help!!!

Answer:

80

4

Step-by-step explanation:

You are correct in placing 80 in the box in the table. If you examine the table and the pattern, you'll see that as the number of marbles increases by 10, the weight of the bags increases by 40.

We can determine the rule by dividing 40 by 10: 40 ÷ 10 = 4.

So, the rule is actually to divide the weight of the bag by 4 to find the number of marbles.

Note that this is likely because each marble is 4 grams.

For Judy's birthday, her friend gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clot
vladimir1956 [14]

Answer:

<h3>The percentage is <u>60%</u> of the total amount paid with the gift card. </h3>

Step-by-step explanation:

Given:

Total worth of clothing is $178.25 and the amount paid with cash is $71.30.

Let us find the part of amount  paid with the gift card:

Amount of gift card(G) = Total worth(T) - Amount paid in cash(C).

G\ =\ 178.25-71.30

G\ =\ 106.95.

So, the amount paid with the gift card is $106.95.

Now, according to question:

\frac{106.95}{178.25}\times100

=0.6\times100

=60%.

Therefore, the percentage is <u>60%</u> of the total amount paid with the gift card.

5000 is 1/10 of what
KatRina [158]
<span>The correct answer is 50,000.

Explanation<span>:
We can set up the equation 5000=1/10x to represent this situation.

To solve, we will divide both sides by 1/10:
5000</span></span>÷<span><span>(1/10) = (1/10x)</span></span>÷<span><span>(1/10)
5000</span></span>÷<span><span>(1/10) = x.

To divide fractions, flip the second one and multiply; this gives us
5000*(10/1) = x
50000 = x.</span></span>

Can someone please help me with this again? 5-7<br><br>Thank you so much! ​

Hi there!

5.

Use the property:

\frac{x^a}{x^b} = x^{a - b}
Now, solve by variable.

\frac{x^2}{x} = x^{2 - 1} = x\\\\\frac{y^5}{y^4} = y^{5 - 4} = y

Rewrite:
= x * y * z^3 = \boxed{\text{ D. } xyz^3}}

6.

Solve the inside of the parenthesis, and each term separately.

Use the property:
x^0 = 1

(7 + 3^2)^0 = 1 \\\\(8^0 + 3)^2 = (1 + 3)^2 = 4^2 = 16\\\\1 + 16 = \boxed{ \text{ C. } 17}

7.

Solve like above:
(4 + 2^2)^0 = 1\\\\(7^0 + 4)^{-3} = (1 + 4)^{-3} = 5^{-3}

The negative exponent indicates taking the reciprocal. Using the property:
x^{-a} = \frac{1}{x^a}

Therefore:
5^{-3} = \frac{1}{5^3} = \boxed{ \text{ D. }\frac{1}{125}}
