Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?
-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks
Answers
the ratio of the scale drawing is
1 inch on the drawing represents 180 feet in real life.
To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:
Actual length / Length on scale drawing = Scale factor
We can plug in the values we know:
60 feet / Length on scale drawing in inches = Scale factor
To solve for the length on the scale drawing in inches, we can cross-multiply:
60 feet * 1 inch / Scale factor = Length on scale drawing in inches
Simplifying:
Length on scale drawing in inches = 60 feet * 12 inches / Scale factor
We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:
4 inches = 60 feet * 12 inches / Scale factor
Solving for the scale factor:
Scale factor = 60 feet * 12 inches / 4 inches
Scale factor = 180

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Two friends, Rahul and Arun, took summer jobs. The equation y = 17.3x represents Arun's earnings in dollars and cents, y, for working x hours. The graph below represents Rahul's earnings in dollars and cents, y, for working x hours.
How much more does Rahul earn per hour than Arun?
Answers
Answer: Rahul earns 3.5 dollars more per hour than Arun.
Step-by-step explanation:
17.3 is the slope of Arun's earnings. To find what Rahul makes in an hour, you can find the slope of his graph below.
Use the two points, (10,208) and (20, 416)
Use the formula for calculating slope:
416-208=208
20-10=10
---------------------
208/10= 20.8
Rahul's equation can be set up like this:
y=20.8x
Subtract:
20.8-17.3=3.5
Therefore, Rahul earns 3.50 dollars more per hour than Arun.
How many yards are in 4 miles?
Answers
Answer: 4 miles are equal to 7040
Step-by-step explanation:
As we know that the ratio can be simplified and the answer can be obtained,
according to the question 5 miles are equal to 8800.
so, here we arrange the ratio in its format as follows
Step 1:
Miles: Yards
5: 8800
Step 2: here we bring the ratio to its simplest form by dividing by 5 on both sides, that is:
5/5=1
8800/5= 1760
Now we get:
Miles: Yards
1: 1760
Step 3: now as we need to find the answer for 4 miles we need to multiply with 4 on both sides, that is:
Miles: Yards
4: 7040
from here we get the answer as 4 milesequalso 7040 yards.

An accountant charges a fee of $120 to complete a company's taxes. The accountant also charges an additional $40 per hour to complete the taxes. Which of the following equations can be used to describe this problem?
y = 40 + 120x
y = 40 − 120x
y = 120 + 40x
y = 120 − 40x
Answers
Answer:
y = 120+ 40x
Step-by-step explanation:
The $40 is the rate of change meaning that that would be the number that is next to the variable and the 120 is just staying there meaning it does not have a variable.
if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The fixed fee of $120 is represented by the constant term in the equation, and the additional fee of $40 per hour is represented by the coefficient of x.
As the number of hours worked by the accountant increases, the total fee also increases at a rate of $40 per hour, hence the linear equation.
The equation that can be used to describe the accountant's fee is:
y = 120 + 40x
In this equation, y represents the total fee, and x represents the number of hours worked by the accountant.
Hence, if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.

Huong spent half of her weekly allowance
on candy. To earn more money her parents
let her wash the car for $6. What is her
weekly allowance if she ended with $14?
Step by step
Answers
Answer:
Let x be Huong's weekly allowance.
According to the problem, she spent half of her weekly allowance on candy. This means she spent (1/2)x on candy.
Then, she earned an additional $6 by washing the car. So her total earnings for the week are (1/2)x + $6.
Finally, we know that she ended up with $14 after all her spending and earning, so we can set up the equation:
(1/2)x + $6 = $14
Subtracting $6 from both sides gives:
(1/2)x = $8
Multiplying both sides by 2 gives:
x = $16
Therefore, Huong's weekly allowance is $16
She ended the week with $14 after spending half of her allowance on candy and washing the car. So she spent half of her allowance and earned $6.
$14 is what she ended with. $6 was added that week. So if we got rid of the additional $6 she earned that week. We get $8.
$14 - $6 = $8
If she did not wash the car then half of the allowance she didn’t spend would be $8. That’s is half so add the other half and you get
$8 + $8 = $16 / $8 x 2 = $16
