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.

Jeff buys two pairs of shoes for $50 each. He can use the following coupons:
Coupon 1: Buy one get one 40% off
Coupon 2: 25% off the entire purchase
Which coupon should Jeff use for the better deal? How much will he save from the original price with this coupon?
Answers
Answer:
Jeff should use coupon #2 for a better deal, as he will save $25 with this coupon.
Step-by-step explanation:
First, we need to apply each respective coupon to the same purchase.
Coupon 1:
⭐How do you take 40% off of a number?
let x = the numberx - 0.4xSo if Jeff buys 1 pair of shoes for $50, the 2nd pair of shoes will only cost him 40% off of $50.
Let's calculate what 40% off of $50 is:
\(x - 0.4x =\)
\(50 - 0.4(50) =\)
\(50 - 20 =\)
\(= 30\)
Now, add the cost of 1 pair of shoes ($50) to the cost of 40% off of 1 pair of shoes ($30) to see how much Jeff will have to pay using coupon #1:
50 + 30 = $80
∴ Jeff will pay only $80 when purchasing with Coupon #1.
Coupon #2:
⭐How do you take 25% off of a number?
let y = the numbery - 0.25ySo if Jeff buys 2 pair of shoes for $100 (50*2), the total cost will only be 25% off of $100.
Let's calculate what 25% off of $100 is:
\(y - 0.25y =\)
\(100 - 0.25(100) =\)
\(100 - 25 =\)
\(= 75\)
∴ Jeff will pay only $75 when purchasing with Coupon #2.
75 is less than (<) 80.
Therefore, Coupon #2 gives Jeff a better deal.
If Jeff had bought the two pairs of shoes without any coupons, it would cost him $100.
To find how much Jeff is saving using Coupon #2, subtract how much Jeff spends using Coupon #2 from $100, the original price.
\(savings = 100 - 75\)
\(savings = 25\)
∴ Jeff saves $25 when purchasing with Coupon #2.
Answer: Jeff should use coupon #2 ($25 off)
Step-by-step explanation:
Coupon #1: The first step in figuring out how much money Jeff would save with coupon #1 is by multiplying $50 by 0.40 in order to find out the discount, which is $20. The next step is to subtract the discount from the original price to find out the discounted price, which is $30. However, this is only the price for one of the pairs of shoes. The final step is to add the $30 discounted pair with the $50 undiscounted pair.
This totals to $80.
\((50)(0.40)=20\)
\(50-20=30\)
\(30+50=80\)
Coupon #2: The second coupon follows a very similar process. The first step is to add the two coupons together to find the price of the entire purchase, which is $100. The next step is to multiply the price by 0.25 to find the discount, which is $25. Next, subtract the discount of $25 from the original price to find the discounted price, which is $75.
This totals to $75.
\(50+50=100\)
\((100) (0.25)=25\)
\(100-25=75\)
So, as you can see, the coupon that saves more money is coupon #2.
The amount of money that he will save from the original price is $25

Answers
Probability is the likelihood or chance that an event will occur. The probability that it has your favorite type of meat on it is 1/5
What is probability?Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = expected/total outcome
If there are five different types of meat, then the total outcome is 5
If you select a sandwich without looking, the expected outcome is 1.
Pr(sandwich) = 1/5
Hence the probability that it has your favorite type of meat on it is 1/5

Step-by-step explanation:
If you look at the sides of the triangle, the first one has sides that have values of 10, 18, and 11.
Look at the sides of the second triangle, the values are 40, 72, and 11.
If you look at the common factors of each of these numbers, you'll see that 4 is a common factor, and the length/value of each of the sides of the 1st triangle is multiplied by 4 to get the length/value of the sides of the 2nd triangle.
18 x 4 = 72
11 x 4 = 44
10 x 4 = 40
Therefore, the scale factor is 4.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
