80% of what number is 190
Answer: I would have to say 237.5
(152 is 80% of 190)
Step-by-step explanation:
If 190 is 80% of a number then you need to reverse the process, .8 * 190 = 80% OF 190 but 190 / .8 = 237.5 which means that 190 is 80% of 237.5

Answer:
$125.50
but I'm not sure
Step-by-step explanation:
100÷100=1
1×12=12
100-12=88
jeans with discount = $88
50÷100=0.5
0.5×25=12.50
5000-1250=3750
t-shirt with discount = $37.50
3750+8800=12550
Answer:
125.5
Step-by-step explanation:
100 x .12= 12
100-12=88
50 x .25 = 12.5
50-12.5 = 37.5
88 + 37.5 = 125.5

Answer:
VT = 50√3 , PT = 50
Step-by-step explanation:
Given
PV = 100
With reference angle 60°
hypotenuse (h) = 100
perpendicular (p) = ?
Now
Sin 60° = p/h
√3 / 2 = p / 100
p = √3 * 100 / 2
p = 50√3
Also
With reference angle 30°
hypotenuse (h) = 100
perpendicular (p) = ?
sin 30° = p/h
1/2 = p / 100
p = 100 / 2
p = 50
Hope it will help :)

Apples cost four times as much as oranges per pound. Apples are $2.80 per pound. How much do oranges cost per pound? *
$11.20
$1.20
$0.70
$1.70
Step-by-step explanation:
Apples cost four times as much as oranges per pound.
If the cost of orange =x
then, cost of apples =4x
But,
the costs of apples =2.80$
So,4x=2.80
[tex]\tt{ x=\dfrac{2.80}{4} }[/tex] ⠀
[tex]\tt{ x=0.70\$ }[/tex] ⠀
so,oranges costs for per pound =0.70$

Answer:
1. 285 2. 2 795 3. 26 320
Step-by-step explanation:
19
x 15
95
190
285
To get the 95, multiply 9 x 5, which is 45. Then, carry over the 4 and multiply 1 x 5, which is 5. Add 5 + 4, which is 9, so then you have 95.
To get the 190, you first have to write a 0 in the unit's place because we are working with the tens. Then, you multiply 9 x 1, which is 9. You then multiply
1 x 1, which is 1.
For the final step, you add 95 + 190 = 285 and this is your answer.
Diameter = 28 cm.
H = 25 cm.

Hey, I have already answered these all questions except the last question in your previous question. Make sure to see them.
For the last question, the answer would be the second choice as when times keep flowing, the distance still remains the same (not to be confused with speed.)
Basically when times keep going, the distance will stay the same without any changes.
