Answers
Answer:
-2/1
Step-by-step explanation:
Answer:
The multiplicative inverse is 2
Step-by-step explanation:
In mathematics, we call the number 1 the multiplicative identity because if we multiple any number by 1, we get that same number as our answer. A multiplicative inverse of a number, x, is a number y, such that if we multiply x times y, then we get the multiplicative identity. That is, x × y = 1.
Mrs. MaryAnn is giving treat sacks out for Valentines Day. She has 30 pencils and 42 smiley face stickers. Mrs. Maryann wants each treat sack to be identical with no leftovers Whats the greatest number of treat sacks she can make? How many pencils will be in each treat sack? How many smiley face stickers will be in each treat sack?
Answers
Answer:
6 number treat sacks and
each sack having 5 pencils and 7 smiley face stickers.
Step-by-step explanation:
Given that:
Number of pencils = 30
Number of smiley face stickers = 42
Mrs. MaryAnn wants to divide everything in identical treat sacks so that there are no leftovers.
To find:
The number of greatest number of treat sacks.
Solution:
First of all, we need to find the Highest Common Factor of the two numbers.
Factorization method:
[tex]30 = \underline2\times \underline3\times 5[/tex]
[tex]42 = \underline2\times \underline3 \times 7[/tex]
Here, the common numbers 2 and 3.
So, highest common factor is [tex]2\times 3 = 6[/tex]
If we divide 30 by 6, we get 5 and
If we divide 42 by 6, we get 7
So, if we take 5 pencils and 7 smiley face stickers in one treat sack and if we make 6 such treat sacks then there will be equal division and no leftovers.
Therefore, the answer is:
6 number treat sacks and
each sack having 5 pencils and 7 smiley face stickers.

In a survey of 2,800 people who owned a certain type of car, 840 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answers
Answer:
30% of people surveyed were satisfied with the car.
Step-by-step explanation:
We are given:
Total participants in survey= 2800
People satisfied with car = 840
We need to find percent of the people surveyed were satisfied with the car.
The formula used is: [tex]\frac{People \ satisfied \ with \ car}{Total \ participants \ in \ survey} \times 100[/tex]
[tex]=\frac{840}{2800}\times 100\\=30\%[/tex]
So, 30% of people surveyed were satisfied with the car.

1. Which expression has a value of 30 when x = -1 and y = 3? A. (x - 3^2) · y - 6 B. (x - 3^2) · (y - 6) C. x - 3^2 · (y - 6) D. x - 3^2 · y - 6
Answers
Answer:
B. (x - 3²)(y-6)
Step-by-step explanation:
Find the expression with a value of 30;
when x = -1 and y = 3:
A. (x - 3²).y-6
(-1 - 9).3-6 = -10 x 3 -6 = -30 - 6 = -36
B. (x - 3²)(y-6)
( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30
C. x - 3² . (y-6) = -1 - 9.(3-6)
= -1-9.-3
= -1 - 9 x -3
= -1 + 27
= 26
D. x - 3².y-6 = -1 - 9. 3 - 6
= -1 - 27 - 6
= -34

Answers
Answer:
x = -2
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define equation
x - 5(-x + 1) - 3x - 1 = -12
Step 2: Solve for x
Distribute -5: x + 5x - 5 - 3x - 1 = -12Combine like terms: 3x - 6 = -12Add 6 to both sides: 3x = -6Divide 3 on both sides: x = -2Step 3: Check
Plug in x to verify it's a solution.
Substitute: -2 - 5(-(-2) + 1) - 3(-2) - 1 = -12Multiply: -2 - 5(2 + 1) + 6 - 1 = -12Add: -2 - 5(3) + 6 - 1 = -12Multiply: -2 - 15 + 6 - 1 = -12Subtract: -17 + 6 - 1 = -12Add: -11 - 1 = -12Subtract: -12 = -12−

If an airplane travels at an average speed of 510 mph, how far does the airplane move in 50 minutes?
Answers
Answer:
425 miles
Step-by-step explanation:
Divide 510 by 60 to get miles per minute and then multiply by 50 to get miles in 50 minutes
The airplane move 425 miles in 50 minutes.
what is Speed- Distance Formula?Speed = Distance/TimDistance = Speed X Time, and Time = Distance / SpeedGiven:
Speed= 510 mph
Time= 50 min = 50/60 hour.
So, speed= Distance / Time
510 = Distance / (5/6)
510 x 5/6 = Distance
Distance = 425 miles
Hence, the Airplane travel 425 miles.

Santiago receives $251 Per year and simple interest from three investments. Part is invested at 2% part at 3% and part at 4%. There is $500 more invested at 3% then at 2%. The amount invested at 4% is six times the amount invested at 3%. Find the amount invested at each rate.
Answers
Answer:
2% : $400
3% : $900
4% : $5400
Step-by-step explanation:
Given that :
Total interest received = 251
Let investment at 2% = x
At 3% = 500 + x
At 4% = 6(500 + x) = 3000 + 6x
Simple interest :
Principal * rate * time
At 2%:
Simple interest = 0.02x
At 3%:
Simple interest = 0.03 * (500 + x) = 15 + 0.03x
At 4%:
Simple interest = 0.04 * (3000 + 6x) = 120 + 0.24x
0.02x + 15 + 0.03x + 120 + 0.24x = 251
0.29x + 135 = 251
0.29x = 116
x = 116 / 0.29
x = 400
Amount invested at 2% = x = $400
Amount invested at 3% = $500 + x = 500 + 400 = 900
Amount invested at 4% = 3000 + 6x = $3000 + 6(400) = $3000 + $2400 = $5400
