the ratio of red marbles to blue marbles in a bag is 3:4. if there are 42 marbles in the bag, how many of the marbles are red?
AlexFokin [52]

Answer:

18

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 = 7

Divide the amount of marbles by 7 to find the value of one part of the ratio

42 ÷ 7 = 6 ← value of 1 part of the ratio, thus

red marbles = 3 × 6 = 18

Salsk061 [2.6K]

Answer:

a = 8 ÷ 1/8

Step-by-step explanation:

All I really did was put another variable similar to the x in the original problem, then I changed the numbers to be a bit lower while still keep the original work-- In a short term, I lowered the 9s to 8s.

Answer:

We conclude that:

h(f(-1))  = -2

∴ option D i.e. -2 is correct.

Step-by-step explanation:

Given

f(x) = 4x² - 1

g(x) = 1/2x + 5

h(x) = 2(x - 4)³

To determine

h(f(-1)) = ?

In order to determine h(f(-1)) first we need to determine f(-1).

substitute x = -1 in the function f(x) = 4x² - 1

f(-1) = 4(-1)² - 1

f(-1) = 4(1) - 1

f(-1) = 4-1

f(-1) = 3

so

h(f(-1)) = h(3)

now substitute h = 3 in the function h(x) = 2(x - 4)³

h(x) = 2(x - 4)³

h(3) = 2(3 - 4)³

h(3) = 2(-1)³

h(3) = 2(-1)

h(3) = -2

Thus,

h(f(-1)) = h(3) = -2

Hence, we conclude that:

h(f(-1))  = -2

∴ option D i.e. -2 is correct.
