So 1/5 pound for 7 days
1/5 <span>÷ 7
rewrite the 7 as a fraction of 7/1
1/5 </span><span>÷ 7/1
keep the first fraction, change the division sign to multiplication, flip the second fraction
1/5 * 1/7
multiply across
(1 * 1) / ( 5 * 7)
1/35

She should</span><span> eat 1/35 of a pound each day to make her 1/5 of a pound last a week, or seven days.

Hope this helps</span>

Well, she should eat then 1/5 ÷ 7, that way she'd split the 1/5 lb in 7 equal pieces, one for each day

$\bf \cfrac{1}{5}\div 7\implies \cfrac{1}{5}\div \cfrac{7}{1}\implies \cfrac{1}{5}\cdot \cfrac{1}{7}\implies \cfrac{1}{35}$

Evaluate the following pic

GREYUIT [131]

Answer:

1) $\sqrt{1225}+\sqrt{1024}=67$

2) $\sqrt[3]{-1331}=-11$

3) Evaluating $2:p :: p:8$ we get $p=\pm 4$

4) $x^3+y^2+z \ when \ x=3, y=-2, x=-6 \ we \ get \ \mathbf{25}$

5) $\frac{(-6)^4\times(-2)^3\times(3)^3}{(-6)^6}=-6$

Step-by-step explanation:

1) $\sqrt{1225}+\sqrt{1024}$

Prime factors of 1225 : 5x5x7x7

Prime factors of 1024: 2x2x2x2x2x2x2x2x2x2

$\sqrt{1225}+\sqrt{1024}\\=\sqrt{5\times5\times7\times7}+\sqrt{2\times2\times2\times2\times2\times2\times2\times2\times2\times2}\\=\sqrt{5^2\times7^2}+\sqrt{2^2\times2^2\times2^2\times2^2\times2^2}\\=5\times7+(2\times2\times2\times2\times2)\\=35+32\\=67$

$\sqrt{1225}+\sqrt{1024}=67$

2) $\sqrt[3]{-1331}$

We know that $\sqrt[n]{-x}=-\sqrt[n]{x} \ ( \ if \ n \ is \ odd)$

Applying radical rule:

$\sqrt[3]{-1331}\\=-\sqrt[3]{1331} \\=-\sqrt[3]{11\times\11\times11}\\=-\sqrt[3]{11^3} \\Using \ \sqrt[n]{x^n}=x \\=-11$

So, $\sqrt[3]{-1331}=-11$

3) $2:p :: p:8$

It can be written as:

$p*p=2*8\\p^2=16\\Taking \ square \ root \ on \ both \ sides\\\sqrt{p^2}=\sqrt{16}\\p=\pm 4$

Evaluating $2:p :: p:8$ we get $p=\pm 4$

4) $x^3+y^2+z \ when \ x=3, y=-2, x=-6$

Put value of x, y and z in equation and solve:

$x^3+y^2+z \\=(3)^3+(-2)^2+(-6)\\=27+4-6\\=25$

So, $x^3+y^2+z \ when \ x=3, y=-2, x=-6 \ we \ get \ \mathbf{25}$

5) $\frac{(-6)^4\times(-2)^3\times(3)^3}{(-6)^6}$

We know (-a)^n = (a)^n when n is even and (-a)^n = (-a)^n when n is odd

$\frac{(-6)^4\times(-2)^3\times(3)^3}{(-6)^6}\\\\=\frac{1296\times-8\times 27}{46656}\\\\=\frac{-279936}{46656} \\\\=-6$

So, $\frac{(-6)^4\times(-2)^3\times(3)^3}{(-6)^6}=-6$

Hatshy [7]

Answer:

19,350.4 or 19,350 if they want it rounded

Step-by-step explanation:

To find the mean you must add up all the numbers. Then, divode that sum by the amount of numbers you added up.

Explanation:

16,746 + 18,423 + 20,536 + 19,572 + 21,475 = 96,752

96,752/5 = 19,350.40

A TV that usually sells for $195.72 is on sale for 20% off. If sales tax on the TV is 9%, what is the price of the TV, including

Nuetrik [128]

The total cost of the TV is: $181.57

Work: 195.72 x 0.20 (20%) = 39.14

195.72 - 39.14 = 166.58 <-- Was for the discount now you have to do the tax.

Now Tax, 166.58 + 14.99 = 181.57

Hope this helps!
