Answer:
Step-by-step explanation:
The best way to select the 100 phone calls would be to randomly select the same amount of phone numbers from each individual type of business. This would make sure that there are no bias choices and would be 100% representative of the overall business market in every single type of business. If you choose the first 100 phone numbers you are choosing from only a handful of the same types of business and leaving out a lot of other types of business. This makes it impossible for the information gathered to be representative of the entire market.

Find the value of x, given that 4(3x+2)=44.
Answer:
X=3
Step-by-step explanation:
=> 4(3x+2)=44
=> 12x+8=44 [Multiply the parentheses by 4]
=> 12x=44 - 8 [Transpose 8 of L.H.S to R.H.S]
=> 12x= 36
=> x= (3)

Hayden and Jamie completed 20 math problems together. Jamie completed 2 more than twice the number that Hayden completed. Let p represent the number of math problems Hayden completed. Write an equation that can be used to find the number of math problems that Jamie completed.
Answer:
3p + 2 = 20
Step-by-step explanation:
p = number of math problems Hayden completed
Jamie completed 2 more than = +2
twice the number that Hayden completed = x2
So 2p+2 = number of problems Jamie completed
Since they completed a total of 20 questions, the equation would need another +
(Hayden's problems) + (Jamie's problems) = 20
(p) + (2p+2) = 20
This can be simplified to 3p + 2 = 20, and you can then solve for p

4. Leroy creates customized engraved
birthday cards for his schoolmates.
He charges them $0.75 per card, plus a
dollar for each engraved letter in
the recipient's name. The equation
C=0.75 + l describes the cost of a card
in dollars, c, that has a certain number of
letters in the name, l.
Number of Letters
in Name
Cost of Card
(dollars)
3.75
5.75
6.75
8.75
If you have $10.75 to spend on a card,
how many letters can be in the recipient's
name?
Answer:
10
Step-by-step explanation:
C = 0.75 + L
For L = 3 ; Cost, C = 3.75
3.75 = 0.75 + 3L
3.75 - 0.75 = 3L
3 = 3L
L = 3/3
L = $1
C = 0.75 + 1L
If amount spent is $10.75; C = 10.75
10.75 = 0.75 + L
10.75 - 0.75 = L
10 = L
Number of letters = 10
maths very easy class 8
Answer:
Rs. 333
Step-by-step explanation:
Area of the surface of the cuboidal box to be painted = surface area of the cuboidal box - area of the base
✔️Surface area of the cuboidal box = 2(L*W + W*H + L*H)
L = 6 cm
W = 4 cm
H = 2.5 cm
Surface area of the cuboidal box = 2(6*4 + 4*2.5 + 6*2.5) = 2(24 + 10 + 15) = 2(49)
Surface area of cuboidal box = 98 cm²
✔️Area of base = L*W
= 6*4 = 24 cm²
Area of the cuboidal box to be painted = 98 - 24 = 74 cm²
✔️Cost of painting 74 cm² at Rs. 4.50 per cm² = 74 × 4.50 = Rs. 333
Which expression is equivalent to 6x+8?
A 2(3x-4)
B 2(3x+4)

294÷3=98
Answer:
98 x 3 = 294 or 3 x 98 = 294
Step-by-step explanation:
Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:
3 x 98 = 294
We can also say that 98 x 3 = 294 since it doesn't matter in which order you multiply.

Ben's living room is a rectangular measuring 12 yards x 204" by how many feet does the length of the room exceed the with the length of the room exceeds the width by blank feet
Answer:
The length of the room exceeds the width by 19 feet
Step-by-step explanation:
From the question, the room measures 12 yards x 204", that 12 yards x 204 inches. To determine by how many feet the length of the room exceeds the width, we will first convert both units of measurement ( yards and inches) to feet.
To convert 12 yards to feet,
1 yard = 3 feet
∴ 12 yards will be 3 × 12 feet = 36 feet
To convert 204" to feet
12" = 1 foot
∴ 204" will be 204/12 feet = 17 feet
Hence, the room measures 36 feet × 17 feet
That is, Length of the room = 36 feet
and width of the room = 17 feet
Now, to determine by how many feet the length of the room exceeds the width, we will deduct the width of the room from the length of the room, that is,
36 feet - 17 feet = 19 feet
Hence, the length of the room exceeds the width by 19 feet.

–6w + (–8) + 1 + (–7w)
A. –w – 7
B. –13w – 7
C. w + 9
D. 13w + 9
Answer:
-13w-7
Step-by-step explanation:
-6w+(-8)+1+(-7w)
-6w-8+1-7w
-6w-7w-8+1
-13w-8+1
-13w-7
Answer:
B. -13w-7
Step-by-step explanation:
First, let's simplify the problem by grouping the like terms together: (-6w), (-7w), and (-8), (1).
Second, now that you know the like terms solve them each individually:
(-6w) + (-7w) = -13w
(-8) + 1 = -7
So your answer is -13w minus -7
