1/2 can also be written as 0.5, so you're asking what 6.5% of 580 is. To get 1% you divide by 100 which is 5.8. You can then multiply 5.8 by 6 to get 34.8 (6%). To get 0.5%, you halve 5.8 to get 2.9. Then, you add 2.9 and 34.8 which is 37.7, and that should be your answer! Hope this helped!
Answer:
8 pounds of cheaper candy,
17.5 pounds of expensive candy
Step-by-step explanation:
Let's define some variables. Let's say the amount of pounds of candy that sells for $2.20/lb is x, and the $7.30 is y. Now we can write some equations!
x + y = 25.5
We can start substitution. We can say that x = 25.5 - y. Plugging this into our second equation, we get:
y = 17.5
Plugging this in, we find that:
x = 8.
Answer:
12.5%
Step-by-step explanation:
[First Value – Second Value] ÷ [(First Value + Second Value) ÷ 2] × 100
[50 - 30] ÷ [ 50 + 30] ÷ 2 × 100
20 ÷ 80 ÷ 2 × 100
0.25 ÷ 2 × 100
0.125 × 100
12.5 %
Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%
Answer:
y = 384
Step-by-step explanation:
Find an equation that fits the graph
When the value varies directly, y = kx.
Find k by substituting x and y in the equation
y = kx
48 = 18k
k = 48/18
k = 8/3
To find the value of y when x= 144 by substituting x for 144
y = 8/3 x
y = 8/3 (144)
y = 1152/3
y = 384
y is 384 when x is 144.
