The base's length is 8 and it's width is 7, so it's perimeter will be $2\cdot (7+8)=30$ . To find the lateral area you shoul multiply this with it's height. So, $30\cdot h=150\\ h=\frac { 150 }{ 30 } \\ h=5$ (h is height).

Point b is the midpoint of ac-. if ab= 4x+2 and ac=10x-6, find the length of ac

Natasha2012 [34]

let's bear in mind that B is the midpoint and thus it cuts a segment into two equal halves.

$\bf \underset{\leftarrow \qquad \textit{\large 10x-6}\qquad \to }{\boxed{A}\stackrel{4x+2}{\rule[0.35em]{10em}{0.25pt}} B\stackrel{\underline{4x+2}}{\rule[0.35em]{10em}{0.25pt}\boxed{C}}} \\\\\\ AC=AB+BC\implies 10x-6=(4x+2)+(4x+2)\implies 10x-6=8x+4 \\\\\\ 2x-6=4\implies 2x=10\implies x=\cfrac{10}{2}\implies x= 5 \\\\[-0.35em] ~\dotfill\\\\ AC=(4x+2)+(4x+2)\implies AC=[4(5)+2]+[4(5)+2] \\\\\\ AC=22+22\implies AC=44$

Kimi and Jordan are each working during the summer to earn money in addition to

cluponka [151]

Their earnings would be the same after 4 hours

Let the number of hours be x, and the weekly earning be y

So, the given parameters are:

Kimi

Earnings = $9 per hour
Weekly allowance = $8

So, the equation for Kimi's weekly earning is:

$y =9x + 8$

Jordan

Earnings = $7 per hour
Weekly allowance = $16

So, the equation for Jordan's weekly earning is:

$y = 7x + 16$

Equate both equations

$7x + 16 = 9x + 8$

Collect like terms

$9x - 7x = 16 - 8$

$2x =8$

Divide both sides by 2

$x =4$

Hence, their earnings would be the same after 4 hours

An 11 lb turkey cost $15.00 while the 16 lb turkey is on sale for $20.00. How much would you save with the sale price? Please sh

lidiya [134]

Find the base price per pound, $15/11, or $1.36 = 1lb, then multiply it by 16, 16 x 1.36 = $21.82. Now just subtract $20 from $21.82 = $1.82. So, You would save, on average, $1.82 by buying the sale.

he probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1034

garri49 [273]

Answer:

0.0071 = 0.71% probability that the San Jose Sharks win 9 games in the upcoming month.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the Sharks win, or they do not. The probability of the Sharks winning a game is independent of any other game. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
