Answer:
15.) -21f - 16
16.) 5s + 2t
Step-by-step explanation:
15.)
-12f - 16 - 9f (Distribute 4 through the parentheses)
-21f - 16 (Collect like-terms)
16.)
4s + 2t + s + s - s (Since two opposites add up to zero, remove them from the expression)
4s + 2t + s (Collect like terms)
Select all the expressions that are equal to 761 ÷ 5. 7610 ÷ 50 762 ÷ 6 76.1 ÷ 0.05 7.61 ÷ 0.5 0.761 ÷ 0.005
Answer:
7610 ÷ 50 and 0.761 ÷ 0.005
Step-by-step explanation:
761/5 is 152.2
7610 ÷ 50 = 152.2
762 ÷ 6 = 127
76.1 ÷ 0.05 = 1522
7.61 ÷ 0.5 = 15.22
0.761 ÷ 0.005 = 152.2

Find the area of an equilateral triangle with side length 9.2 cm. Round your answer to 1 DP.
Answer:
Area=36.66 cm^2
Step-by-step explanation:
First, you need the height.
Use the Pythagorean theorem:
hypotenuse^2=height^2+(1/2 base)^2
It's one-half base because it's an equilateral triangle.
1/2 base =4.6
(9.2)^2-4.6^2=height^2
84.64-21.16=height^2
height^2=63.48
height=7.97
Area=(1/2)(base)(height)
Area=(1/2)(9.2)(7.97)=36.66 cm^2
Ellen's living room is 3 meters wide and 8 meters long. She wants to install pink carpet that costs $9.00 per square meter. How much will it cost to buy enough carpet for the living room?
Answer:
$216
Step-by-step explanation:
................
Area of room =(l*b)
=(3*8)m²= 24m²
Carpet needed = 24m²
Cost of 1m² carpet= $9
Cost of 24m² carpet= $(9*24)
= $216
Answer:
i think ur answer would be $243
Step-by-step explanation:
sorry if wrong

Factorize completely
80p2 - 180r2
Answer:
80p2 - 180r2
20(4p²-9r²)
20(2p+3r)(2p-3r)
Answer:
20(2p - 3r)(2p + 3r)
Step-by-step explanation:
Given
80p² - 180r² ← factor out 20 from each term
= 20(4p² - 9r²) ← difference of squares which factors in general as
a² - b² = (a - b)(a + b)
4p² - 9r²
= (2p)² - (3r)² ← with a = 2p and b = 3r
= (2p - 3r)(2p + 3r)
Thus
80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form

Constant termMatt starts swimming lessons on 5 day . He goes every 10 days . How many lessons will Matt go to in 30 days?
Answer: 3 lessons
Step-by-step explanation:
Matt starts swimming lessons on Day 5.
He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:
First lesson = Day 5
Second lesson = Day 5 + 10 days = Day 15
Third lesson = Day 15 + 10 days = Day 25
Fourth lesson = Day 25 + 10 days= Day 35
He therefore only went for 3 lessons because the 4th lesson was after Day 30.

The number of diagonals of a polygon with n sides is given by S (n)=n(n-3)/2
Part A
Which equation shown indicates that a 4-sided polygon has 2 diagonals?
S (2) = 4
S (4) = 2
S (2n) = 4
S (4n) = 2
Part B
What is the value of S (100), and what does it represent?
S(100) = ?
and it means that a polygon with ?sides has diagonals?
Select the three number bonds that represent factor pairs of the number 56. CLEAR CHECK Number bond: 1 times 56 = 56. Number bond: 4 times 14 = 56. Number bond: 5 times 6 = 56. Number bond: 7 times 8 = 56.
Answer:
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.
Step-by-step explanation:
We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.
For example -
5 and 6 are factors of 30 because 5×6 = 30
Now,
Given -
Number bond: 1 times 56 = 56. ...................(1)
Number bond: 4 times 14 = 56. ...................(2)
Number bond: 5 times 6 = 56. ...................(3)
Number bond: 7 times 8 = 56. ...................(4)
In equation (1)
1 times 56 = 1×56 = 56
⇒1 and 56 are the factor pairs of 56
Satisfies
In equation (2)
4 times 14 = 4×14 = 56
⇒4 and 14 are factor pairs of 56
Satisfies
In equation (3)
5 times 6 = 5×6 = 30 ≠ 56
⇒5 and 6 are not factor pairs of 56
Not Satisfies
In equation (4)
7 times 8 = 7×8 = 56
⇒7 and 8 are factor pairs of 56
Satisfies
∴ we get
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.

Which fraction can be replaced with 1 2 when estimating with fractions? A. 10 12 B. 7 16 C. 2 9 D. 1 8
Answer:
B. 7/16
Step-by-step explanation:
The answer to this question is the option whose value is closest to 1/2.
We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5
10/12 = 0.833
7/16 = 0.43
2/9 = 0.222
1/8 = 0.125
The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.
Thank you!
