Answer:
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
Step-by-step explanation:
Given that :
Age of 10 friends are consecutive integers :
Let the ages be :
x, x+1, x+2, x+3, x+4, x+5, x+6, x+7, x+8, x+9
The sum of their ages = 710
Hence,
x + x+1 + x+2 + x+3 + x+4 + x+5 + x+6 + x+7 + x+8 + x+9 = 710
10x + 45 = 710
10x = 710 - 45
10x = 665
x = 665 / 10
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
The temperature dropped from 23°C to -16°C.
By how many degrees did the temperature drop?
The temperature drops when the temperature goes down from 23°C to -16°C is 39°C.
What is subtraction?It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.
The temperature dropped from 23°C to -16°C.
Then the drop in temperature will be
Temperature drop = 23 - (-16)
Temperature drop = 23 + 16
Temperature drop = 39 °C

Complete question :
Victor left his house riding his bike at a speed of 18 km/h. When Victor was 1/2 km away from his house his brother Alex left the house riding at a rate of 24 km/h. How long will it take Alex to catch up with Victor?
Answer:
0.083333 or 5 minutes
Step-by-step explanation:
Victor's speed = 18 km/hr
Alex's speed = 24 km/hr
Alex left after Victor has moved a distance of 1/2 km
Time Alex will catch up with Victor :
Let time = x
distance at which Victor = Alex
(18 * x) + 0.5 = (24 * x)
18x + 0.5 = 24x
18x - 24x = - 0.5
-6x = - 0.5
x = 0.5 / 6
x = 0.0833333 hour
x = 0.0833333 *60 = 5 minutes

Ameron works for a car dealership and earns a monthly salary plus a commission for every car he sells.(8.5B) Which equation could be used to find Cameron's total monthly income, M, after selling n cars? M = 500n + 1750 M = 1750n + 2250 M = 1750n + 500 M = 2250n
Answer:
Equation used to calculate monthly income of Ameron is: M = 1750+500n
Step-by-step explanation:
From the question it is give that :
monthly salary of Ameron is 1750 and commission for every car he sells is 500
let n be the Number of car he sells then its total income M of the month is
M = 1750 + 500n
Therefore correct option is (a) i.e., M = 1750+500n

A promoter buys advertising in units of $30,000 each. If he buys two units of broadcast TV, one unit of cable TV, and two units of radio, how much does he spend in advertising?
Answer:
$150,000
Step-by-step explanation:
The first step is to calculate the total number of units
= 2 +1 +2
= 5
If he buys at the rate of $30,000 for one unit then the total money spent on advertising can be calculated as follows
= 30,000 × 5
= 150,000
Hence the promoter spends $150,000 on advertising

Mrs. Goerlich deposited $2,000 into a savings account to save for her son's college tuition. • The account earns simple interest. • She did not make any additional deposits or withdrawals. • At the end of 6 years, the account has a balance of $2,780. What is the annual interest rate on this account?
Answer: 6.5%
Step-by-step explanation:
In 6 years the interest earned is:
= 2,780 - 2,000
= $780
The account earns simple interest which means that it increased by the same rate yearly. Yearly increase is:
= 780/6
= $130
Simple interest rate = Interest payment/ Deposit
= 130/2,000
= 6.5%

Answer:
The answer is $82.88.
Step-by-step explanation:
Too complicated. Will do explanation later.
Answer: You're correct :3
Step-by-step explanation:
15% of 78.93 ≈ 11.84
78.93 - 11.84 = 67.09
20% of 78.93 ≈ 15.79
67.09 + 15.79 = 82.88

Answer:
Angle A = 15
Angle B: 105
Step-by-step explanation:
Angle A and 75° add up to 90°
75 + x = 90
x = 90 - 75
x = 15
Angle B and 75° add up to 180°
75 + x = 180
x = 180 - 75
x = 105
The graph shows f(x) and its transformationg (x)
Which equation correctly modelsg (x)?
g(x) = 3^x-7 – 2
g (x) = 3^x+7 - 2
g(x) = 3^x+2 - 7
g(x) = 3^x-2-7
Answer:
[tex]g(x) = {3}^{x - 2} - 7[/tex]
Step-by-step explanation:
As we can see, the graph of transformation of f(x) is translated to the right and down.
then, g(x) = f(x - a) - b, where a & b > 0.
from the options, there are 4 translated function of f(x).
but on the second option
[tex] {3}^{x + 7} - 2 = {3}^{x - ( - 7)} - 2[/tex]
a < 0, then it's not the answer we need, same as third option that makes only first and fourth left.
from the picture, horizontal asymptote of f(x) is y = 0.
on g(x) horizontal asymptote is y = -b, where -10 < -b < -5.
and from the options that are left, we can see only fourth option that satisfies what we need.

6 xy × 4 = 2 x72 please koi solutions do
Answer:
y = 6
Step-by-step explanation:
6 * y * 4 = 2 * 72
y = 2 * 72/24 = 6
6xy × 4 = 2 × 72
or, 6xy = 2 × 72/4
or, 6xy = 36
or, xy = 6
6 = 3 × 2 × 1
Hence, x = 3 and y = 2
or, x = 2 and y = 3
or, x = 6 and y = 1
or, x = 1 and y = 6

The question that can be answered using the expression can be 1/3 of the total apple pie is divided in to 3/4 parts.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 1/3 ÷ 3/4.
Here the operation is division.
So 1/3 of something is divided in to 3/4 parts.
Let a total amount of something be 1/3 units.
Suppose you have to divide it into 3/4 parts.
Then this expression can be used.
Let the total amount of apple pie left is 1/3 part of the total.
You have to divide t into 3/4 parts.
Hence the word problem can be 1/3 of the total apple pie is divided in to 3/4 parts.

The population of Kenya was 45.1 million in 2009 and has been growing by 2.3% each year. If this trend continues, in what year will the population exceed 52.2 million?
Answer:
6.4294 years
Step-by-step explanation:
45.1 million in 2009 -- 2.3% each year
In what year will the population exceed 52.2 million?
We use exponential growth formula
ξ(t) = y = ab^t
a = 45.1, b = 1+ξ, ξ= 2.3%, ξ(t) = 52.2
52.2/45.1 = (1.023)^t
We take log both side
Log(1.15742794) = tlog(1.023)
0.0634939619 = t0.00987563371
t = 0.0634939619/0.00987563371
t = 6.429355701569454
t = 6.4294 years

The perimeter of a triangle is 21. The smallest side is 3. The 2nd side is twice the smallest side. The 3rd side is 6 more than the 2nd side. Write an equation to solve for the perimeter. Then find the ____ and ____.
Fill in the blanks.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the smallest side is 3 and that the 2nd side is twice the smallest side. This means that the second side will be:
= 3 × 2 = 6
The 3rd side is 6 more than the 2nd side. The 3rd side will be:
= 6 + 6 = 12
The perimeter of a triangle is the addition of its sides. Therefore, the perimeter is:
= 3 + 6 + 12
= 21
The sides are:
1st side = 3
2nd side = 6
3rd side = 12.
