There is 180 degrees in a triangle. What you need to do is set up an equation and solve for x.

(7x + 10)+(x+20)+2x =180

Combine like terms:

10x + 30 = 180

Solve for x:

10x= 150; the largest angle

X=15

Plug x into the equations

7(15)+10= 115

(15) + 20 = 35

2(15)=30

Just to check your work:

115+30+35=180

An accounting firm has recently recruited six graduates: three men and three women. Three of the graduates are to be selected at

solong [7]

Answer:

a) The probability tree is constructed below

b) the probability that at least two women will be selected is 0.500

Step-by-step explanation:

Given the data in the question;

a) The probability tree is as follows;

3 men, 3 women

↓

_______________________|________________________

↓ ↓ ↓ ↓

3 men 2 men 1 man 0 men

0 women 1 woman 2 woman 3 women

b) the probability that at least two women will be selected

p( at least two women would be selected) = P( there are 2 women out of 3 ) + P( there 3 women out of 3

p( at least two women would be selected) = C

³C₂ × ³C₁ / ⁶C₃ + ³C₃³C₀ / ⁶C₃

= 3!/(2!(3-2)!) × 3!/(1!(3-1)!) / 6!/(3!(6-3)!) + 3!/(3!(3-3)!) × 3!/(0!(3-0)!) / 6!/3!(6-3)!)

= 3 × 3 / 20 + 1 × 1 / 20

= 9/20 + 1/20

= 0.45 + 0.05

p( at least two women would be selected) = 0.500

Therefore, the probability that at least two women will be selected is 0.500

Show how to solve the problem 378 x 6 using place value with regrouping. Explain how you knew when to regroup.

KIM [24]

<u>Answer</u>

2,268

<u>Explanation</u>

<u>By grouping 378 ca</u>n be written as,

378 = 300 + 70 + 8

6× 378 = 6 × (300 + 70 + 8)

= (6×300) + (6×70) + (6×8)

= 1800 + 420 + 48

= 2,268

I would like to have an answer for this thanks!

Scilla [17]

The final amount of the compound interest after 6 years would be $ 294, 122, 500

<h3>How to determine the final amount</h3>

The formula for the final amount is given as;

$A = P( 1 + \frac{r}{n}) ^n^t$

Where

A = final amount

P = principal interest

r = interest rate

n = number of times

t = time of periods

We have,

A = $2500$ $( 1 + \frac{6}{1}) ^1^*^6$

A = $2500 ( 7)^6$

A = $2500$ × $117, 649$

A =$ $294, 122, 500$

Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500
