The ratio of doves to parrots in a cage is 1 to 2. If there are 6 doves and parrots altogether then how many parrots are there?

1 answer:

6 0

There would be 2 doves and 4 parrots.

2 + 4 = the 6 in total, and the ratio between doves (2) and parrots (4) is 1 to 2 because the ratio of 2 to 4 is equal to 1 to 2.

Workout the area of the quarter of a circle with a radius of 8

QveST [7]

Answer:

$16\pi$

Step-by-step explanation:

We need to find 1/4 of the area of a circle with a radius of 8

Let r be radius

Area of a circle = $r^{2} \pi$

Substitute r with 8

Area of a circle = $8^2\pi =64\pi$

Now, to find 1/4 of the area, we can create an equation $\frac{64\pi }{4}={16\pi$

The answer is $16\pi$

A figure is shown with the given dimensions.

Illusion [34]

Answer:

$\blue{A = 24~ft^2}$

Step-by-step explanation:

This figure is a trapezoid with bases of 10 ft and 6 ft and height of 3 ft.

$A = \dfrac{b_1 + b_2}{2}h$

$A = \dfrac{10~ft + 6~ft}{2} \times 3~ft$

$\blue{A = 24~ft^2}$

Find the missing probability. P(A)=7/20,P(A∪B)=191/400,P(A∩B)=49/400 ,P(B)=? A. 7/8 B. 1/4 C. 117/400 D. 19/40

spin [16.1K]

Answer:

Step-by-step explanation:

P(AUB)=P(A)+P(B)-P(A∩B)

191/400=7/20+P(B)-49/400

P(B)=191/400+49/400-7/20=240/400-7/20=12/20-7/20=5/20=1/4
