Answer:
She should mix 9 g of powder
Step-by-step explanation:
From the question, we can have a ratio for powder to water
we have 5 g of powder mixed with 45 cm^3 of water
So, for every 1 g, we have 5g/45 cm^3
we have 9 cm^3
So let’s relate this to the bigger water mix
Recall from above; we have the mixing as 1 g per 9 cm^2 of water
1g per 9 cm^2
x g per 81 cm^2
81 * 1 = x * 9
9x = 81
x = 81/9
x = 9g
Answer:
$60
Step-by-step explanation:
1200*0.05 = $60
Slope=-5
as the line goes 5 down and 1 right
Answer: Our required equation would be
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x
Answer:
x=52
Step-by-step explanation:
90+34
124
180 (sum of all interior angles) - 124
56
x+72+56=180 (straight line)
x+128=180
-128 -128
x=52
*replace to verify*
52+72= 124
124+56= 180 (straight line)
