5. Ten workers are fencing a 25 m by 28 m stadium. They had finished fencing 95 m.
How many more metres of fence co they need to build?
A. 11 m
C. 148 m
B. 106 m
D. 201 m​

Answers

Answer:

A. 11 m

Step-by-step explanation:

Given that

the ten workers are fencing  25 m by 28 m

And, they finished the fencing 95 m

We need to find out the number of more meter of fence that could be developed

So,

= (25+25) + (28+28)

= 106 - 95

= 11

Hence, 11 more meters should be build

Therefore the correct option is A.

Step-by-step explanation:

If the smaller angle is s, then the sum of the two angles is ...

  s + 59s = 180°

  s = 180°/60 = 3° . . . . . divide by the coefficient of s

  59s = 177° . . . . . . . . . find the larger angle

Heather received a 90 gift card for a coffee store. She used it in buying some coffee that cost $8.49 per pound. After buying the coffee, she had $56.04 left on
her card. How many pounds of coffee did she buy?

Answers

Answer:

Latoya bought 4 pounds of coffee.

Step-by-step explanation:

it sounds like you want to know how many pounds of coffee Latoya bought. First, let's figure out how much she spent. Subtract the amount she has left from the amount she started out with:

90 - 57.68 = 32.32

Latoya spent $32.32 on coffee. Since it cost $8.08 per pound, we can divide the total cost by 8.08 to figure out how many pounds she bought:

32.32/8.08 = 4

Latoya bought 4 pounds of coffee.

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots. Which is the total weight of the lettuce and carrots in ounces?
A. 10 ounces
B. 12 ounces
C. 40 ounces
D. 72 ounces

Answers

The total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots.

As we know:

1 pounds = 16 ounces

Amount of lettuce = 8 ounce


Amount of carrots = 2 pounds = 2×16 = 32 ounces

Total weight of the lettuce and carrots in ounces =  8 + 32 = 40 ounces

Thus. the total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

5. PA license plates have 3 letters followed by 4 numbers.
a. If the same letter or number can be repeated, how many can be made?
b. If the same letter CANNOT be repeated, how many can be made?

Answers

Answer:

A. 175,760,000

B. 156,000,000

Step-by-step explanation:

For part A:

There are 26 letters in the alphabet.  Therefore, if there are 3 spots to use 26 letters, that is represented as [tex]26^3[/tex].  As for numbers, there are 10 digits from 0-9.  So if there are 4 spots for numbers, the total possible number of sequences is [tex]10^4[/tex].  So you simply multiply [tex]26^3[/tex] and [tex]10^4[/tex] to get 175,760,000 possible combinations.

For part B:

If the same letter can't be repeated, instead of using an exponent, we have to use a factorial, but only for the 3 digits required in the license plate.  These are called permutations and can be expressed as [tex]_2_6P_3[/tex], which is the same as saying 26 x 25 x 24.  Since there is no change to number of numbers, that remains the same.

[tex]_2_6P_3 * 10^4 =26*25*24*10^4=156,000,000[/tex]

Solve for x.

3x - 20
x = [?]

Answers

Answer:

x= 7

3x-20

2x+15

you would add 3x+2x equals 5x and 20 +15= 35

5x+35

35 divided by 5 is 7 and then on the 5x divide by 5 and leaves x=7

Answer:

35

Step-by-step explanation:

Angles 2x + 15 and 3x - 20 are adjacent angles.

Adjacent angles are equal.

3x - 20 = 2x + 15

3x - 2x = 15 + 20

x = 35
