140 grams of almonds cost $3.5. Mechael needs almonds for the dish she is preparing. How much she has to pay for 500 grams of almonds cost?
Answers
Answer:
$12.5
Step-by-step explanation:
140 divided by 7 is 20, since 20 is a factor of 500, it will make it easier. Since we divided the 140 grams by 7, we also have to divide the $3.5 by 7, which will get you$0.5. 20 times 25 is 500, so you will also time the $0.5 by 25 which will get you $12.5
(a) 3 - 2/3÷4/3 × 7
(b) [(2/3)/(5/6)]-2/5
(c) {(-3/4) +( 1/2)}/{(2/5)-(5/2)}
Answers
Step-by-step explanation:
a. (3 - 2/3) ÷ (4/3 x 7)
= [(3 x 3) / (1 x 3) - 2/3] ÷ 28/3
= (9/3 - 2/3) ÷ 28/3
= 7/3 x 3/28
= 21/84
= (21 x 1) / (21 x 4)
= 1/4
b. 2/3 ÷ 5/6 - 2/5
= 2/3 x 6/5 - 2/5
= 12/15 - 2/5
= (3 x 4) / (3 x 5) - 2/5
= 4/5 - 2/5
= 2/5
c. (- 3/4 + 1/2) ÷ (2/5 - 5/2)
= [- 3/4 + (1 x 12) / (2 x 2)] ÷ [(2 x 2) / (5 x 2) - (5 x 5) / (2 x 5)]
= (- 3/4 + 12/4) ÷ (4/10 - 25/10)
= 9/4 ÷ (- 21/10)
= 9/4 x - 10/21
= - 90/84
= (6 x - 15) / (6 x 14)
= - 15/14.

Two numbers have a sum of 24 and a difference of 5. Use and algebraic method to find the two numbers.
Answers
Step-by-step explanation:
x, y are the 2 numbers
x + y = 24
x - y = 5
x = y + 5
and that in the first equation
y + 5 + y = 24
2y = 19
y = 9.5
x = y + 5 = 9.5 + 5 = 14.5
the 2 numbers are 9.5 and 14.5.
Emily spends $28 on food. This amount of 4/9 of her allowance, what is Emily’s allowance?
please help with explanation !
Answers
Answer:
$63
Step-by-step explanation:
so we want to find 9/9 of her allowance, which is 100%
we could use a proportion:
let 'a' = full allowance
[tex]\frac{28}{1}[/tex] ÷ [tex]\frac{4}{9}[/tex] = [tex]\frac{a}{1}[/tex] ÷ [tex]\frac{9}{9}[/tex]
when we divide fractions we multiply by the reciprocal to get:
28 x 9/4 = a
a = 252/4
a = 63

The power, P(watts), of a car engine is proportional to the square of its speed, s(m/s).
When s=45 P=2200.
Work out the speed (to 1 DP) when the power is 1890 watts
Answers
The speed of the car is 41.7 m/s when the power is 1890 watts.
What is Proportion?Proportion is defined as an equation on which two or more ratios are made to be equal to each other.
It is given that the power, P is proportional to square of the Speed,s.
If P ∝ s², then P = k s², for some constant k.
When s = 45 m/s, P = 2200 watts
k = P / s² = 2200 / 45² = 1.086
∴ when P = 1890 watts,
1890 = 1.086 × s²
s² = 1740.331
s = 41.717 ≈ 41.7 m/s
Hence, if power is proportional to the square of the speed, then, the speed of the car engine is 41.7 m/s if the power is 1890 watts.

299 divided by 21 step by step
Answers
Start by setting it up with the divisor 21 on the left side and the dividend 299 on the right side like this:
2 1 ⟌ 2 9 9
Step 2:
The divisor (21) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
2 1 ⟌ 2 9 9
Step 3:
Multiply the divisor by the result in the previous step (21 x 0 = 0) and write that answer below the dividend.
0
2 1 ⟌ 2 9 9
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
2 1 ⟌ 2 9 9
- 0
2
Step 5:
Move down the 2nd digit of the dividend (9) like this:
0
2 1 ⟌ 2 9 9
- 0
2 9
Step 6:
The divisor (21) goes into the bottom number (29), 1 time(s). Therefore, put 1 on top:
0 1
2 1 ⟌ 2 9 9
- 0
2 9
Step 7:
Multiply the divisor by the result in the previous step (21 x 1 = 21) and write that answer at the bottom:
0 1
2 1 ⟌ 2 9 9
- 0
2 9
2 1
Step 8:
Subtract the result in the previous step from the number written above it. (29 - 21 = 8) and write the answer at the bottom.
0 1
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8
Step 9:
Move down the last digit of the dividend (9) like this:
0 1
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
Step 10:
The divisor (21) goes into the bottom number (89), 4 time(s). Therefore put 4 on top:
0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
Step 11:
Multiply the divisor by the result in the previous step (21 x 4 = 84) and write the answer at the bottom:
0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
8 4
Step 12:
Subtract the result in the previous step from the number written above it. (89 - 84 = 5) and write the answer at the bottom.
0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
- 8 4
5
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 299 divided by 21 calculated using Long Division is:
