Answer:

x = 15

Step-by-step explanation:

hope this helps, have a great day/night!!

Answer:

15

Step-by-step explanation:

40=8(x - 10)

Distributive property

40 = 8x - 80

Add 80 on both side

120 = 8x

Divide both sides by 8

120/8 = 15

x = 15

Answer:

Step-by-step explanation:

Input the function f(x) = x^2 + 4x + 3 and graph it (using the calculator) for the interval [-5, 5].  The roots are the x values at which this graph crosses the x axis and are {-3, -1).  The axis of symmetry is the vertical line through x = -2.

[tex]F = \frac{9}{5} c + 32[/tex]

This Equation Is Used For Conversion Of Celcius To Fahrenheit.

Answer: Uhmm ok the answer i got would have been F = C x 9/5 + 32 But since there isn't a choice like that I think it's the second one- its the closest to what i got--

Answer:

35%

Step-by-step explanation:

Answer:

3/8

Step-by-step explanation:

If ive read this correctly it's asking what is 25% times 1.5, that would be 0.25 times 1.5 which is 0.375 turned into a fraction could be 375/1000 or simplified would be 3/8 as both are divisable by 125.

Given:

The table of values.

To find:

Whether the given relation in the table is proportional or non proportional.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

It means the ratio of y and x remains same for proportional relation.

From the given table, the points are (10,18), (11,18.6) and (12,19.2). The ratio of y to x for these points are:

[tex]\dfrac{18}{10}=1.8[/tex]

[tex]\dfrac{18.6}{11}\approx 1.69[/tex]

[tex]\dfrac{19.2}{12}=1.6[/tex]

Since the ratio of y to x for the given points are not equal, therefore the given relation is a non proportional relation.

Answer:

B

Step-by-step explanation:

Graph shrinks, that means for every x value there is a higher y value. So coefficient of x is definitely more than 1. Try to substitute x = 1 to (9x)^2 and (3x)^2.

(3(1))^2 = 9

Hope this helps. Tell me if I'm wrong

Answer: Probably 30

Step-by-step explanation: If you multiply 12 x 5 = 60, which we don't see that answer. I'll say C because 12 + 12 is 24. Add 5 and you get 29. The closer answer to 29 is 30. I could be wrong because I'm only in Middle School and kinda get confused with questions like these.

The value of the expression (0.01) × (−0.1) × (10) × (−100) will be 1.

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (0.01) × (−0.1) × (10) × (−100)

Simplify the expression, then we have

⇒ (0.01) × (−0.1) × (10) × (−100)

⇒ (0.01) × (0.1) × (10) × (100)

⇒ 1

The value of the expression (0.01) × (−0.1) × (10) × (−100) will be 1.

Answer:

10 multiplied by 40 give me 400 so it's $400 and they also using the word each

Answer:

$27

Step-by-step explanation:

We have to find 6% of $450. We can make an expression and solve it:

6/100•450

We can cancel out factors now:

3/50•450

Now we'll cancel out 50 and 450:

3x9=$27

And that's your answer! Hope this helps =)

Answer: B, Parallelogram, and rectangle

Step-by-step explanation:

A parallelogram requires two parallel sides which that shape has.

A rectangle requires all angles to be right angles and that shape has all angles being right angles.

The shape is not a rhombus since all sides are not the same and it's not a square for the same reason.

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorem:

85^2 = 67^2 + h^2, where h is the height of the TV

Then 7225 = 4489 + h^2, or

h^2 = 2736, or h = +√2736 = 52.3 inches

The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

We have:

A certain television is advertised as a 85 inch TV

It means the diagonal length is 85 inches.

Width of the TV = 67 inches

Let's suppose the TV is x inches Tall

So from the Pythagoras theorem:

[tex]\rm 85^2 = x^2+67^2[/tex]

7225 = x² + 4489

x = 52.30 inches

Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

Answer:

x = people who chose pepperoni = 252

Step-by-step explanation:

Number of people : people who chose pepperoni = 25 : 18

how many people would you expect to choose pepperoni

out of 350 people?

Let x = people who chose pepperoni

Number of people : people who chose pepperoni = 350 : x

Equate both ratios

25 : 18 = 350 : x

25/18 = 350/x

Cross product

25*x = 18*350

25x = 6,300

x = 6,300/25

x = 252

x = people who chose pepperoni = 252

Answer:

Reduction

Step-by-step explanation:

So, lets go over what we know:

The black rectnagle is the orginal shape.

The organe rectnalge is the new shape.

The organge rectangle is smaller than the black rectangle.

The rogane rectangle is a scaled image of the black rectangle.

So, enlargment is when a object has a scale factor that makes it bigger than the orgninal object.

Reduction, on the other hand, is when a object has a scale factor that makes it smaller than the orginal object.

As we can see, the organe rectnagle is much smaller than the black rectnalge.

So this must be reduction, since the organe rectangle has a small scale factor that causes the shape to shrink in size.

Hope this makes sense and helps you! :)

Answer:

b=6

a=6

hypotenuse=6√ 2

Step-by-step explanation:

This is a 45, 45, 90 triangle. This means a=b and hypotenuse is equal to b times √ 2. This means that you have to divide the hypotenuse by √ 2 to get what b is equal to 6√ 2 divided by √ 2 is equal to 6. Therefore, b=6. Because b and a are equal, a is also equal to 6. Therefore, b=6, a=6.
