What is the value of q ? 2/5(g-7)=3

Mathematics
1 answer:
Thepotemich [5.8K]3 years ago
4 0

Answer:

q = 29/2    ( decimal: q = 14.5)

Step-by-step explanation:

multiply both sides by 5

5 * 2/5 (q - 7) = 3 * 5

simplify

2 (q - 7) = 15

divide both sides by 2

(2 (q - 7))/(2) = 15/2

simplify

q - 7 = 15/2

add 7 to both sides

q - 7 + 7 = 15/2 + 7

simplify

q = 29/2

Consider that the length of rectangle A is 10 cm and its width is 6 cm. Which rectangle is similar to rectangle A? A) A rectangl
HACTEHA [7]
ANSWER

B) A rectangle with a length of 15 cm and a width of 9 cm.

EXPLANATION

The given rectangle, A, has length, 10cm and its width is 6cm.

The rectangle that is similar to rectangle A, has the corresponding sides in the same proportion.

For option A, the triangle has length 9cm and width 6cm.

The ratio of the corresponding sides are:

\frac{10}{9} \ne \frac{6}{6}

Since the ratios are not equal, the two triangles are not similar.

For the triangle in option B, the length is 15cm and the width is 9cm.

The ratio of the corresponding sides are:

\frac{10}{15} = \frac{6}{9} = \frac{2}{3}

Since the sides of the triangle are in the same proportion, the two triangles are similar.

For option C, the proportions are not the same.

\frac{10}{14} \ne \frac{6}{7}

The proportions are not the same for the triangle in option D.

\frac{10}{12} \ne \frac{6}{8}

My lawn is 17ft wide and 20ft long, each square foot of lawn gets 1350 new snowflakes per min how much snow in kilograms accumul
Alina [70]

Answer:

46.818 kg

Step-by-step explanation:

First, find the surface area of your yard. This is found by multiplying the length and width.

The equation for this is (l*w)=sa

So,

l=20ft

w=17ft

(20*17)= 340 square feet.

So, if each square foot gets 1350 new flakes per minute, you are going to find how much the entire yard gets in a minute by multiplying the surface area by 1350.

So,

(340*1350)= 459000  flakes for the entire yard in one minute.

Since there is 60 minutes in an hour, multiply 459,000 by 60.

459,000*60= 27,540,000  new flakes in the yard per hour.

Now, to find the weight in milligrams:

27,540,000*1.7= 46,818,000  mgs

Finally, because a kilogram is equal to one million milligrams (mg),

46,818,000/1,000,000= 46.818 kg
