What are proportions?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.

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)

Add 10 on both sides
-52+10=6x-10+10
-42=6x
Divide 6 on both sides
-42/6=6/6x
x=-7

You would like to have $200,000 in a college fund in 15 years. How much do you need today if you expect to earn 12% while you are investing to pay for your child's college?
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.
given -6b+22>-8 what is the largest integer b can represent
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.

An electric pole, 14 metres high, casts a shadow of 10 metres. Find the height of a tree that casts
a shadow of 15 metres under similar conditions.
As shadow is directly propotional to height, we can say that,
Height/Shadow =k, where k is a constant.
So, in case of electric pole,
1410=k→(1)
In case of tree,
HT15=k→(2), where HT is height of tree
So, from (1) and (2),
1410=HT15
HT=14∗1510=21m
So, height of tree is 21 meters.

To make a salad dressing, a chef uses a ratio of 2 ounces of oil to 6 ounces of vinegar. The chef needs 24 ounces of dressing. How much oil is needed? 2 ounces 4 ounces 6 ounces 8 ounces 12 ounces also 8 ounces isn't right and when you find the answer can you show me how you worked it out?
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.

Use graphing technology to find the range of the function f(x)=x2 +6x+9
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]

*PLEASE ANSWER ASAP* John is playing a game with two friends. Using the spinner pictured, one friend spun a three, and the other friend spun a five. John needs to spin a number higher than both friends in order to win the game, and he wants to calculate his probability of winning. How many desired outcomes should John use in his probability calculation?
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.
What is probability?Probability is the measure of the likelihood of occurrence of an event.
What is outcome?An outcome is a possible result of an experimental or trial.
Formula to calculate probability[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.

A box measuring 11 inches by 10 inches by 7 inches is filled with solid wooden cubical blocks, each measuring 3 inches per side. How many wooden blocks can fit into the box
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...*

Step-by-step explanation:
Angle F and angle G are complementary . The measure of angle F is three times the measure of angle G. What is the measure of each angle?
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:
✦ 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
