Evaluate 4g−12 when g=5

Answer:

[See Below]

Step-by-step explanation:

✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:

  ✧ Square ∼ s² (Side Squared)

  ✧ Triangle ∼ ½ × b × h

✦ So now just solve for each area:

  ✧ Square ∼ 15² = 225

  ✧ Triangle ∼  ½ × 15 × 3 = 22.5

✦ Now add each area together to get the total area:

  ✧ 225 + 22.5 = 247.5

Answer:

y = 1/2x + 3

O f(x)= 1/2x+3

Step-by-step explanation:

f(x) = 2x - 6

y = 2x - 6

x = 2y - 6

2y = x + 6

y = (x + 6)/2

y = 1/2x + 3

The sales price would be $36.00

How I got this answer:

Discount: (45 x 20)/100 = $9.00 the nine dollars is your discount.

Final pricing:

45 - 9.00 = $36.00 when you subtract the cost with the discount you should get thirty-six dollars.

Answer:

6 ounces of oil

Step-by-step explanation:

Well the first salad dressing is probably 8 ounces because 2+6 = 8

Then we must find out how large this recipe compares to the original

24/8 = 3

So we need all the ingredients to be tripled to keep the same ratio of 2:6

The new dressing has 2*3 ounces of oil and 6*3 ounces of vinegar

which equals 6 ounces of oil and 18 ounces of vinegar.

Hope this helps!

Answer:

3

Step-by-step explanation:

Because Johns friends both got 3 and 5 so he needs a number higher to win i.e 6, 7, 8 so the answer is three.

Second  Option is correct.  

There will be  3 desired outcomes John should use in his probability calculation.

Probability is the measure of the likelihood of occurrence of an event.

An outcome is a possible result of an experimental or trial.

[tex]P(A) = \frac{number of favorable outcomes }{Total number of outcomes}[/tex]

where,

P(A) is the probability of an event.

According to the given question

we have

sample space = {1,2,3,4,5,6,7,8}

Total number of outcomes = 8

Jhon needs to spin a number higher than both friends in order to win the game

⇒ the numbers must be greater than 5

⇒ the numbers will be 6, 7, 8

therefore,

the total number of favorable outcomes =3.

Hence. there are 3 desired outcomes should John use in his probability calculation.

Answer: OPTION 3. -7

Step-by-step explanation:

Given

-52=-4x-5(-2x+2)

Distributive property (REMEMBER you need to change signs)

-52=-4x-5×(-2x)-5×2

-52=-4x+10x-10

Combine like terms (-4x and 10x)

-52=6x-10

Add 10 on both sides

-52+10=6x-10+10

-42=6x

Divide 6 on both sides

-42/6=6/6x

x=-7

Hope this helps!! :)

Please let me know if you have any question

[tex]-52=-4(-7)-5(-2(-7)+2)\\-52=28-5(14+2)\\-52=28-70-10\\-52=28-80\\-52=-52[/tex]

Answer:

$36,529.26

Step-by-step explanation:

To find the answer, you need to use the formula to calculate the present value:

PV=FV/(1+i)^n, where:

PV= present value

FV= future value= $200,000

i= interest rate= 12%

n= number of periods of time= 15

Now, you have to replace the values in the formula:

PV=200,000/(1+0.12)^15

PV=200,000/(1.12)^15

PV=36,539.26

According to this, the answer is that you need $36,529.26 today.

Answer:

28

Step-by-step explanation:

[tex]number \: of \: wooden \: blocks \\ = \frac{volume \: of \: box}{volume \: of \: one \: wooden \: block} \\ = \frac{11 \times 10 \times 7}{3 \times 3 \times 3} \\ = \frac{770}{27} \\ = 28.51 \\ [/tex]

Thus, there would be 28 full wooden blocks in the box.

Answer: 28 wooden blocks

Step-by-step explanation: First you must find the volume of the box with the formula: L × W × H so, 10 × 11 × 7 = 770 inches³. Second you must find the volume of the wooden blocks with the formula: x³ ( 'x' is the value of the side of the cube ) so, 3 × 3 × 3 = 27 inches³. Now you can divide the volume of the box by the volume of the wooden block = 770 ÷ 27 = 28.518...*

Answer:

5

Step-by-step explanation:

-6b> -8-22

-6b> -30

b> -30/-6

b>5

Answer:

So we have this inequality:

[tex]-6b + 22 > -8[/tex]

We substract 22 on both sides:

[tex]-6b > -30[/tex]

Now, we divide both sides by -6 and we change the sign, as, when we multiplicate or divide by a negative number we always have to do it:

[tex]b < \frac{-30}{-6}[/tex]

[tex]b < 5[/tex]

So we know b < 5, so the biggest integer b can represent is 4. Note that the solution is any number which is smaller than 5.

Answer:

See below.

Step-by-step explanation:

Refer to the graph.

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values is all values greater than or equal to 0.

Therefore, our range is, in interval notation:

[tex][0,\infty)[/tex]

Note that we use brackets with the 0 because 0 is included in our range.

In set notation, this is:

[tex]\{y|y\in\mathbb{R},y\geq 0\}[/tex]

Answer:

[tex]g[/tex] = 22.5°

[tex]f[/tex] = 67.5°

Step-by-step explanation:

Let’s create a system of equations for [tex]f[/tex] and [tex]g[/tex].

Complementary angles are two angles that add up to 90°, so [tex]f+g=90[/tex]

Also, [tex]f[/tex] is thrice of g: [tex]f=3g[/tex]

We can now substitute [tex]3g[/tex] in [tex]f+g=90[/tex] for [tex]f[/tex].

[tex]3g + g = 90\\\\4g = 90\\\\g=22.5[/tex]

Now, we can find [tex]f[/tex] by substituting [tex]g[/tex] into either equation.

[tex]f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5[/tex]

Step-by-step explanation:

92=$9.20

100?

920/100x110/92

After this you will get 11 dollars.

That is the amount to send 110 text messages.

The cost to send 110 text messages is $11.

Given that, it cost Paisley $9.20 to send 92 text messages.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the cost to send 110 text messages be x.

Now, 9.20:92::x:110

⇒ 9.20×110=92×x

⇒ 92x=1012

⇒ x=1012/92

⇒ x=$11

Hence, the cost to send 110 text messages is $11.
