A bowl contains blueberries and strawberries there are a total of 20 bares in the bowl the ratio blueberries to strawberries is

Alexus [3.1K]

Answer:

16 blueberries and 4 strawberries

Step-by-step explanation:

Given:

A bowl contains blueberries and strawberries there are a total of 20 berries in the bowl.

The ratio blueberries to strawberries is 4 to 1

Question asked:

How many of each berry are in the bowl ?

Solution:

Ratio of blueberries and strawberries = 4 : 1

Let ratio be $x$

Number of blueberries in the bowl = $4x$

Number of strawberries in the bowl = $1x=x$

As total berries in the bowl are 20 and the bowl contains both blueberries and strawberries in the ratio 4 : 1 :-

$4x+x=20\\5x=20\\$

Dividing both sides by 5

$x=4$

Number of strawberries in the bowl = $x$ = 4

Number of blueberries in the bowl = $4x$ = $4\times4=16$

Thus, there are 16 blueberries and 4 strawberries in the bowl.

For f(x)=4x+1 and g(x)=x^2-5,find(f•g)(4)

RoseWind [281]

Answer:

(f•g)(4) = 45

Step-by-step explanation:

f(x)=4x+1

g(x)=x^2-5

(f•g)(x) = 4(x^2 -5)+1

(f•g)(4) = 4(4^2 -5)+1

(f•g)(4) = 4(16-5)+1

(f•g)(4) = 4(11)+1

(f•g)(4) = 44 + 1

(f•g)(4) = 45
