Translate the sentence into an equation. The sum of 3 times a number and 7 is 19.

D. Because you're multiplying 3 by a number which is what the variable represents (n), then you're just adding 7 to that which equals 19 all together. It all translates to 3n+7=19.

Can someone help me with this q?

Answer:

rounded = 170 in^3 and 2nd question =2.772 in^3

Step-by-step explanation:

h: 12 1/8 = 12.125

w: 1 3/4 = 1.75

l: 8

----------------------------------

h*w*l = 169.75 in^3

rounded = 170 in^3

oh there's another.. wait

same with this question

.----------------------------------

h*w*l

10.5 * 12 * 22 = 2.772 in^3

in a Billiards game, peter hits a ball that is 20 in. from the wall The ball travels 34 inches until it hits the wall and bounce

Andrei [34K]

Answer:

27.2 inches

Step-by-step explanation:

Given :

Refer the attached figure

ΔABC AND ΔEDC are right angled triangle at B and D respectively

So we will use trigonometric ratios :

$sin\theta=\frac{perpendicular}{hypotenuse}$

IN ΔABC perpendicular = AB=20 inches and hypotenuse = AC=34 inches

$sinC=\frac{AB}{AC}$

$sinC=\frac{20}{34}$

IN ΔEDC perpendicular = ED=16 inches and hypotenuse = EC=x inches

$sinC=\frac{ED}{EC}$

$sinC=\frac{16}{x}$

Since ∠ACB = ∠ECD

⇒ $\frac{16}{x}=\frac{20}{34}$

⇒ $\frac{16*34}{20}=x$

⇒ $27.2=x$

Thus distance X the ball traveled after it bounces off the wall to get to the ending position =27.2 inches
