The sum of three consecutive numbers is 84. What is the largest of these numbers? (5 points) a 28 b 26 c 29 d 27
Answer:
The answer is c.29
Step-by-step explanation:
I used Google xD
Answer:
Largest number = 29
Step-by-step explanation:
Let the consecutive numbers by (x + 1) ; (x + 2) and (x +3)
x +1 + x + 2 + x + 3 = 84 {Combine like terms}
x + x +x + 1 + 2 + 3 = 84
3x + 6 = 84
3x = 84 - 6
3x = 78
x = 78/3
x = 26
Largest number = x + 3 = 26 + 3
=29

23.82600 round to three significant figures
Answer:
23.8 i think
Step-by-step explanation:
Answer:
[tex]23.83[/tex]
Step-by-step explanation:
[tex]--------------------------------------------[/tex]
According to Maths3000, Rounding to 3 significant figures is probably the most common way of rounding off. Rounding the number off to 3 significant figures means you require 3 non-zero digits from the start of the number. So in example 1, 27.1258 gets rounded to 27.1 figures.[tex]--------------------------------------------[/tex]
It is 23.83 because rounding by three significant figures is picking three of the last numbers, and rounding the 4th number. In this case, 6 is more than 5, so 23.82 becomes 23.83

Answer:
- 0.4 (in decimal)
Step-by-step explanation:
Here "x" is input and "f(x)" is output
Average Rate of Change is = change in output / change in input
At x = 0, the output is 41
At x = 60, the output is 17
= (17-41)/(60-0) = -24/60 = -0.4

The basketball coach made up a game to play where each player takes 10 shots at the basket. For every basket made, the player gains 10 points. For every basket missed, the player loses 15 points.
a. The player with the highest score sank 7 baskets and missed 3. What was the highest score?
b. The player with the lowest score sank 2 baskets and missed 8. What was the lowest score?
c. Write an expression using addition to find out what the score would be if a player sank 5 baskets and missed 5 baskets.
Answer/Step-by-step explanation:
A. (7 x 10) = 70
(3 x -15) = -45
70 + -45 = 25
B. (2 x 10) = 20
(8 x -15) = -120
20 + - 120 = - 100
C. (5 x 10) + ( 5 x -15) or 5 x (10 + -15)
5 x 10 = 50
5 x -15 = -75
50 + -75 = -25

Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight training is 3 to 2. How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training?
Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week
Solution:
Given that,
Kay spends 250 min/wk exercising
Therefore,
Exercising = 250 minutes per week
Ratio of time spent on aerobics to time spent on weight training is 3 to 2
Aerobics : weight training = 3 : 2
Let the time spent on aerobics be 3x
Let the time spent on weight training be 2x
Thus,
3x + 2x = 250
5x = 250
x = 50
Thus,
Time spent on aerobics = 3x = 3(50) = 150
Time spent on weight training = 2x = 2(50) = 100
Thus, Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week

An airplane is 4,000 feet above the ground. It begins to descend at a rate of 140 feet per minute. How many minutes will it take until the plane is 2,600 feet above the ground?
Answer:
10 minutes!
Step-by-step explanation:
140 * 10(min) = 1,400
4000 - 1,400 = 2,600 ft
so will take 10 minutes for the plane to descend 1,400 ft
Answer:
10 minutes
Step-by-step explanation:
in five minutes it will descend by 700 feet so multiply that by 2 you get 1400 and thats how much to add and thats 10 minutes so 10

The value of r in the given linear equation 2r + 7 =16 is 9/2.
What is linear equation in one variable?
A linear equation in one variable is an equation which has maximum of one variable of order 1. It is of the form ax + b =0, where x is the variable.
Solving Linear Equation in one variableFor solving an equation having one variable, the following steps are followed:
Step1: Using LCM, clear the fractions if any.Step2: Simplify both sides of the equation.Step 3: Isolate the variable.According to the given question
We have, a linear equation in variable r.
2r +7 =16
⇒ 2r + 7 -7 = 16 -7
⇒ 2r = 9
⇒ r = 9/2
Hence, the value of r is 9/2 for the given linear equation 2r + 7 = 16.

What’s 123.45 + 67.891
Step By Step?
Answer:
123.45 + 67.891 = 191.341
Step-by-step explanation:
I don't know really know how to explain but I'll try to. So since 123.45 is the larger decimal so you put it first then below it you put 67.891.(not that it is necessary)
Then add a zero to 124.45. Meaning it will be 123.450. (It is the same number, we just have to add a zero there.)
Add then just add like you normally do. Just try doing it and you'll see.

Jina is saving money to buy a bike. She has $63 and is going to save an additional $9 each week. The bike costs $198. In how many weeks will she have
enough money to buy the bike?
(a) Write an equation that could be used to answer the question above.
First, choose the appropriate form. Then, fill in the blanks with the
numbers 63, 9, and 198. Let w represent the number of weeks.
Answer:
Jina will have enough money to buy the bike in 15 weeks
Step-by-step explanation:
y = mx + b
198 = 9x + 63
Subtract 63 from both sides;
135 = 9x
Divide both sides by 9;
x = 15
