Step-by-step explanation:

Answer:

-4 over 5

Step-by-step explanation:

The line goes through the points (-3,1) and (2,-3) which means for every 5 x-values it goes to the right, it goes down 4 values. Meaning -4 over 5

Answer:

angle one=122 because it is using the alternate interior angle theorem

angle 2=58 because it is using the consecutive interior angle theorem

hope this helps

have a good day :)

Step-by-step explanation:

remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58

since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle

Answer:

Choice C

Step-by-step explanation:

$80 to 5 hours

Divide both numbers by 5 to find the unit rate:

$16 to 1 hour, or 16 to 1

For x hours, the pay, y, is y = 16x.

Choice A is true.

Look at choice B.

When x = 5, y = 80.

This is correct because we are given that information.

The process is to multiply the hours by 16.

For x hours, y = 16x (from choice A)

For x = 7, y = 7 * 16

Choice B works.

Look at choice C.

We need a proportion. The left side is the ratio 80/5, meaning $80 for 5 hours of work. Notice that the first number in the ratio is dollars, and the second number is hours. Now we need another ratio written in the same order to set up a proportion. x dollars is to 7 hours. This is the ratio x/7. The correct proportion is

80/5 = x/7

Choice C is 80/5 = 7/x

Choice C is incorrect.

Look at choice D.

The graph shows that for 5 hours, the pay is $80, so by looking up x = 7, you can find the correct amount of pay.

Choice D works.

Answer: Choice C

Answer:

y = ax2 + bx + c

Step-by-step explanation:

1) Standard form: y = ax2 + bx + c where the a,b, and c are just numbers.

2) Factored form: y = (ax + c)(bx + d) again the a,b,c, and d are just numbers.

3) Vertex form: y = a(x + b)2 + c again the a, b, and c are just numbers.

Answer:

Each slice of bread costs $0.06.

Step-by-step explanation:

To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.

Answer:

0.9/15=$0.06 per slice

Also what is this 1910 when did a loaf of bread cost 90 cents????

Answer:

The length of the other leg will be = 4

Step-by-step explanation:

You have to use your Pythagoras theorem to determine the length of the other leg.

Hypotenuse^2=a^2+b^2

since you are given the length of the hypotenuse and one leg you can change the formula to:

b^2 = h^2 - a^2

b = √h^2-a^2

b=√5^2-3^2

b=√25-9

b=√16

b=4

Answer:

B

Step-by-step explanation:

Answer:

y=-5x

Step-by-step explanation:

take two points, I took 0,4 and 1-,1 and do

y2-y1 over x2-x1

The letter “n” notates “number” and refers to any number, similar to “x.” The little carat means they the number following, in this case a 2, is an exponent. So this can really be understood as “x squared.” Most likely, this term appeared in an equation.

Answer: hello your question lacks vital data hence I will provide you with a general equation within the scope of your question

answer :

General equation = ( Stiver and Mackay or EPA ) evaporation equations

E = [tex]\frac{PAW}{T +459.67}[/tex]  or  E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]

Step-by-step explanation:

Given data

volume of water in pool = 0.9 i.e. 90% full

rate of evaporation = 7.5ft^3  per day = 56.1039 gallons / day

Assumption :

Volume of pool = 16,000 gallons

In order to resolve the missing part of the problem  apply the equation below

E = [tex]\frac{PAW}{T +459.67}[/tex]   or   E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]

where : E = Evaporation rate , P = water's vapor pressure ,  A = pool surface Area , W = wind speed ,  T = Temperature in Fahrenheit

Answer:

D. step 4

Step-by-step explanation:

he did it all right but made it 3 units down not 4 so he made mistake in step 4.

Answer:

x = 9

Step-by-step explanation:

These are alternate exterior angles and alternate exterior angles are equal if m is parallel to n

6x+5 = 7x-4

Subtract 6x from each side

6x -6x+5 = 7x-6x-4

5 = x -4

Add 4 to each side

5+4 =x-4+4

9 =x

Answer:

m∠6 = 110°

Step-by-step explanation:

∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.

Answer:

11o degree

Step-by-step explanation:

angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.

Answer:

x=2

y=1

Step-by-step explanation:

2x+y=5

3x+2y= 8

<=> 6x+3y=15

6x+4y=16

<=> -y=-1

2x+y=5

<=> y=1

2x+1=5

<=> y=1

2x=4

<=> y=1

x=2

Answer:

Unsure, sorry

Step-by-step explanation:

Answer:

t=6

Step-by-step explanation:

h(t) = -16t^2 +64t + 192

We want h(t) =0

0 = -16t^2 +64t + 192

Factor out -16

0 = -16 (t^2 -4t -12)

Factor.  What terms multiply to -12 and add to -4   -6*2 = -12  -6+2 = -4

0 = -16(t-6)(t+2)

Using the zero product property

0=t+2     0=t-6

t = -2   t=6

But t=-2 happens before the event occurs   so the solution is t=6

Answer:

x = 52

Step-by-step explanation:

An isosceles triangle is a triangle with two congruent sides, meaning two sides have the same measure. One property of an isosceles triangle is the base angles theorm. This theorem states that the angles opposite the congruent sides in an isosceles triangle are cognruent. Applying this theorem to the given triangle, one can state the following:

52 = x

Answer:

I think the answer is 52 so x=52

A triangular pyramid has 4 vertices and triangular prisms 6 vertices

Answer:

a) x = -10

b) x = 7

Step-by-step explanation:

a)

2(x + 3) = x - 4

2x + 6 = x - 4

2x - x = -4 - 6

x = -10

b)

4(5x - 2) = 2(9x + 3)

20x - 8 = 18x + 6

20x - 18x = 6 + 8

2x = 14

x = 7
