The area of a square window is
given by the expression
m’ - 16m+64. Which expression
represents the length of one side
of the window?
a)m - 8
b) m + 4
c)m - 4
d) m + 8

Part A:

8t + 5h = 220

t + 5h = 112

Part B:

T-shirt cost $13.50

Hat cost $22.40

Answer:

(0, 4 ) and (2, - 4 )

Step-by-step explanation:

(2)

3x + 4y = 16 → (1)

- 3x + 2y = 8 → (2)

Adding (1) and (2) term by term will eliminate the x- term

0 + 6y = 24

6y = 24 ( divide both sides by 6 )

y = 4

Substitute y = 4 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(4) = 16

3x + 16 = 16 ( subtract 16 from both sides )

3x = 0 , then

x = 0

solution is (0, 4 )

(3)

2x - 4y = 20 → (1)

5x + 4y = - 6 → (2)

Adding (1) and (2) term by term will eliminate the y- term

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (2)

5(2) + 4y = - 6

10 + 4y = - 6 ( subtract 10 from both sides )

4y = - 16 ( divide both sides by 4 )

y = - 4

solution is (2, - 4 )

Answer:

yes, he still needs all the buses he hired

Step-by-step explanation:

768 people/56 people per bus = 13.71, so 14 buses

768 - 19 = 749 people going

749people/56 people per bus = 13.37, so still need 14 buses

Complete Question:

The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.

Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?

Answer:

The height is 36 meters

Step-by-step explanation:

Given

[tex]y = 24 * \frac{x}{10}[/tex]

Required

The interpretation of the question is to determine the value of y when x = 15

Substitute 15 for x in: [tex]y = 24 * \frac{x}{10}[/tex]

[tex]y = 24 * \frac{15}{10}[/tex]

[tex]y = 24 * 1.5[/tex]

[tex]y = 36[/tex]

The height is 36 meters

Answer:

[tex]Boys = 1 /4[/tex]

[tex]Total =112[/tex]

Step-by-step explanation:

Given

[tex]Girls= 3/4[/tex] ---  missing information

[tex]Boys = 28[/tex]

Solving (a): The fraction that are boys

We have:

[tex]Girls= 3/4[/tex]

This implies that

[tex]Boys = 1 - Girls[/tex]

[tex]Boys = 1 - 3/4[/tex]

[tex]Boys = 1 /4[/tex]

Solving (b): Students in the class

If 1/4 are boys, then:

[tex]Boys = \frac{1}{4} * Total[/tex]

We also have that: [tex]Boys = 28[/tex]

So:

[tex]28= \frac{1}{4} * Total[/tex]

[tex]28 * 4 = Total[/tex]

[tex]112= Total[/tex]

[tex]Total =112[/tex]

Answer:

You should study hard and look through the test first to answer the ones you do know and then go back to the ones you don't know. Also if you use any methods or anything related to help with math try to use those through. Therefore try your best and just prepare for it, and always have supplies.

Answer:

1.5 moles

Step-by-step explanation:

number of moles = no. of particles / Avagadro number

therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23

therefore, no. of moles = 1.5

There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

Answer:

P-E-M-D-A-S

Step-by-step explanation:

Ok, so start with what i call "P-E-M-D-A-S"

P: parentheses | Also known as these: ( )

E: exponents | Its a small number by another number, like the 3 on your screen

M: Multiply | Also Known as   x or a dot

D: Divide | i forgot how to make it

A: Add | also known as +

S: Subtract | also known as -

now go in order to solve it, it makes it much more easy!

Answer:

49 is your answer

Step-by-step explanation:

let's do b-pemdas

brackets

parentheses

e(I forgot the name for it but it's basically a small number next to the big number)

Multiply

Divide

Add

Subtract

you do the equation in that order

so

2+8•7-(3^2)

we focus on (3^2)

that's 3•3 which equals to 9

so now the equation is

2+8•7-9

Now we focus on 8•7 which equals to 56

the equation now looks like

2+56-9

you then add 56 to 2 which equals to 58 and then subtract 9 from it so it should look like this

2+56=58

58-9= 49

and 49 is your answer

hope this help!!!

Answer:

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average price for a gallon of gasoline in France is $5.54. The standard deviation is $.25.

This means that [tex]\mu = 5.54, \sigma = 0.25[/tex]

What is the probability that a randomly selected gas station in France charges more than $5.30 per gallon?

This is 1 subtracted by the pvalue of Z when X = 5.30. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5.3 - 5.54}{0.25}[/tex]

[tex]Z = -0.96[/tex]

[tex]Z = -0.96[/tex] has a pvalue of 0.1685

1 - 0.1685 = 0.8315

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Answer:

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].

Step-by-step explanation:

First, we decompose the number given on statement by applying prime numbers in ascending order. We see that 200 is an even number, therefore, we infer that smallest prime number within is 2.

1) [tex]\frac{200}{2} = 100[/tex] (Even number)

2) [tex]\frac{100}{2} = 50[/tex] (Even number)

3) [tex]\frac{50}{2} = 25[/tex] (Even number)

4) [tex]\frac{25}{5} = 5[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

5) [tex]\frac{5}{5} = 1[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

Now, we construct the prime factorization using exponential notation:

[tex]200 = 2^{3}\times 5^{2}[/tex]

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].

Answer:

y = 2x - 1

Step-by-step explanation:

-1 is the y-intersect of the slope

Answer:

x = 2

y = 152°

Step-by-step explanation:

✔️9x + 10 = 15x - 2 (corresponding angles theorem)

Collect like terms

9x - 15x = -10 - 2

-6x = -12

Divide both sides by -6

x = -12/-6

x = 2

✔️y + (15x - 2) = 180° (same-side interior angle theorem)

Plug in the value of x

y + (15*2 - 2) = 180

y + 28 = 180

y = 180 - 28

y = 152

Answer:

B : 10 cm^3

Step-by-step explanation:

L x W x H = V

4cm x 2cm x 1 1/4 (1.25) = 10cm^3

1 1/4 = 4 x 1 = 4 + 1 = 5/4 = 1.25

Hope this helps!

I am pretty sure this is right.
