There are 87 girls and 58 boys!

i divided 5 from 145 and got 29.
i multiplied 29 and 3 and got 87.
87 is the girls total.
then subtracted 87 from 145 and got 58.
58 is the boys total.

hope this helps!

Answer:

<h2>You Can do this in two ways. I will shaw both, the first one is more common and more easy :</h2>

Method 1:

3/5 of 145 = girls

boys = girls - boys or 2/5

3/5 x 145 = 87

girls = 87

boys = 145-87 = 58

Method 2:

3/5 of 145 = girls

boys = girls - boys or 2/5

3/5 x 145 = 87

girls = 87

2/5 x 145 = 58

boys = 58

The people of Whoville were shopping like crazy to get their lists completed! one customer bought a wreath for $12 and seven orn

Bezzdna [24]

Answer: 6 dollars

Step-by-step explanation: since the total price is 54 dollars and we know the price of the wreath, we subtract the wreath from the total, leaving us with 42. Then we do 42 divided by 7 to get the price per ornament(which is too high to be reasonable in any universe), 6 dollars.

Draw the figure with their measurements and find their volume

babunello [35]

1) Volume = L × W × H = 8 × 3 × 5 = <u>120 m³</u>

2) Volume = s³ = 17³ = 17 × 17 × 17 = <u>4913 cm³</u>

3) Volume = s³ = 30³ = 30 × 30 × 30 = <u>27000 cm³</u>

4) Volume = L × W × H = 13 × 5 × 7 = <u>455 cm³</u>

5) Volume = s³ = 15³ = 15 × 15 × 15 = <u>3375 cm³</u>

Formula's applied:

(a) Volume of rectangle: Length × Width × Height

(b) Volume of Cube: (side)³

Find the equation of the circle in standard form for the given center (h, k) and radius R:(H,K)=(4/3,-8/8),R=1/3

Scorpion4ik [409]

Answer:

<h3>The answer is option B</h3>

Step-by-step explanation:

Equation of a circle is given by

( x - h)² + ( y - k)² = r²

where r is the radius and

( h , k) is the center of the circle

From the question the radius R = 1/3

the center ( h ,k ) = (4/3 , -8/3)

Substituting the values into the above equation

We have

$(x - \frac{4}{3} )^{2} + {(y - - \frac{8}{3}) }^{2} = ({ \frac{1}{3} })^{2}$

We have the final answer as

$(x - \frac{4}{3} )^{2} + {(y + \frac{8}{3}) }^{2} = \frac{1}{9}$

Hope this helps you
