One thumbtack weighs 0.25 ounce. How many thumbtacks are in a box that has a mass of 3500 grams? (Hint: 1oz ~28g

1 answer:

7 0

Alright so .25 oz is 1/4 of 1oz. Therefore you take 28 and divide it by 4 and get 7.

Then take 3500 and divide it by 7 which makes 500 thumb tacks.

I think idk though.

What values of c and d make the equation true?

saul85 [17]

Answer:

Third option.

Step-by-step explanation:

You need to cube both sides of the equation. Remember the Power of a power property:

$(a^m)^n=a^{mn$

$\sqrt[3]{162x^cy^5}=3x^2y(\sqrt[3]{6y^d})\\\\(\sqrt[3]{162x^cy^5})^3=(3x^2y(\sqrt[3]{6y^d}))^3\\\\162x^cy^5=27x^6y^36y^d$

According to the Product of powers property:

$(a^m)(a^n)=a^{(m+n)$

Then. simplifying you get:

$162x^cy^5=162x^6y^{(3+d)}$

Now you need to compare the exponents. You can observe that the exponent of "x" on the right side is 6, then the exponent of "x" on the left side must be 6. Therefore:

$c=6$

You can notice that the exponent of "y" on the left side is 5, then the exponent of "x" on the left side must be 5 too. Therefore "d" is:

$3+d=5\\d=5-3\\d=2$

The height of a trapezoid is 6 in. and its area is 36 in2. One base of the trapezoid is 6 inches longer than the other base. Wha

nignag [31]

Answer:

3 inches and 9 inches

Step-by-step explanation:

Area of a trapezoid is given by

A = 1/2 (b1+b2)*h where b1 and b2 are the lengths of the bases

b1 =b

b2 =b1+6 = b+6

h =6

A = 36

Substituting in what we know

36 = 1/2 (b+b+6)*6

Simplifying

36 = 3 (2b+6)

36/3 = 3/3 (2b+6)

Divide each side by 3

12 = 2b+6

Subtract 6 from each side

12-6 =2b+6-6

6 =2b

Divide each side by2

6/2 =2b/2

3=b

b1 =b =3

b2 =b1+6 = b+6 = 3+6 =9

One base is 3 and the other is 9
