Easy. Do (3x + 10) + (6x -10) = 180. You add them up since they are same side interior angles. This gives you 9x = 180
Divide by 9 on both sides. x = 20. Hope this helps!

Answer:

The answer to your question is: V = 5x² + 40x + 80

Step-by-step explanation:

Formula = V = r²h

r = x + 4

h = 5

Substitution

V = (x + 4 )² 5

V = (x² + 8x + 16)5 expand

V= 5x² + 40x + 80 simplify

Answer:

The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Step-by-step explanation:

Mean = $\mu = 45$

Population standard deviation = $\sigma = 6$

Sample size = n =25

Sample mean = $\bar{x} = 52$

We are supposed to find the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e. $P(x\geq 52)$

$Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{52-45}{\frac{6}{\sqrt{25}}}$

Z=5.83

P(Z<52)=0.9999974

$P(Z\geq 52)=1-P(z$

Hence the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Solve the simultaneous equation<br> 2p_3q=4<br> 3p+2q=9

kirill [66]

Answer:

Step-by-step explanation:

2p-3q=4

or p=4+3q/2

now putting the value in the second eq we get

3 x(4+3q/2)+2q=9

or 12+9q /2 +2q=9

or 12+9q+4q=18

or 13q=18-12

or q= 6/13

so p will be 4+18/13=70/13 divided by 2 so p=35/13

Don Chather bought a new Dell computer for $1,995. This included a 6% sales tax. What is the amount of sales tax and selling pri

yan [13]

6% of $1,995 = 1995 x 0.06 = 119.70
1995 - 119. 70 = 1875.30

Sales tax = $119.70
Selling price before tax = $1,875.30
