In three months the food bill will be $210 this is because

120x.25=30

30x3=90

120+90=210

A fruit stand sells apples, peaches and tomatoes. Today, they sold 4 apples for every 5 peaches. They sold 2 peaches for every 3

Brrunno [24]

Answer:

He sold 32 apples, 40 peaches and 60 apples.

Step-by-step explanation:

We are given that

4 apples are sold every 5 peaches and

3 tomatoes are sold every 2 peaches.

i.e. the ratio is apples: peaches = 4 : 5 ...... (1)

and the ratio peaches: tomatoes = 2 : 3 ...... (2)

Peaches are the common link here in both the ratio terms.

Let us make the peaches value in both the ratio as 10 to make it equal in both the ratio terms.

Multiply (1) by 2 and (2) by 5:

The ratio becomes;

apples:peaches = 8:10

peaches: tomatoes = 10:15

In other words, the ratio becomes:

apples:peaches:tomatoes = 8:10:15

Let the number of apples = $8x$

Let the number of peaches = $10x\\$

Let the number of tomatoes = $15x$

We are given that total fruits are = 132

$\Rightarrow 8x+10x+15x = 132\\\Rightarrow 33x = 132\\\Rightarrow x =4\\$

So, number of apples sold = $8 \times 4 = 32$

Number of peaches sold = $10 \times 4 = 40$

Number of tomatoes sold = $15 \times 4 = 60$

If the volume of the planter is 3,072 cubic inches, how tall is the planter?

andrezito [222]

$\it \mathcal{V} =\dfrac{\mathcal{A}_b\cdot h}{3} \Rightarrow h = \dfrac{3\mathcal{V}}{\mathcal{A}_b}= \dfrac{3\cdot3072}{\mathcal{A}_b}\ \ \ \ \ (*)
\\\;\\ \\\;\\
\mathcal{A}_b = \dfrac{\ell^2\sqrt3}{4} = \dfrac{16^2\sqrt3}{4} =\dfrac{16\cdot16\sqrt3}{4} =4\cdot16\sqrt3=64\sqrt3\ \ \ \ (**)
\\\;\\ \\\;\\
(*),\ (**) \Rightarrow h=\dfrac{3\cdot3072}{64\sqrt3} = \dfrac{3\cdot48}{\sqrt3} = \dfrac{\sqrt3\cdot\sqrt3\cdot48}{\sqrt3} = 48\sqrt3\ inches$

Answer:

The total surface are is 252 sq. units.

Step-by-step explanation:

The right triangular sides have legs 8 units and 6 units and hypotenuse 10 units.

So, their area will be $2(\frac{1}{2} \times 8 \times 6) = 48$ sq. units.

Now, the length of the prism is 8.5 units.

So, the area along the length will be = (8.5 × 6 + 8.5 × 8 + 8.5 × 10) = 204 sq. units.

Therefore, the total surface area is (48 + 204) = 252 sq. units. (Answer)

Look at the figure, O PORS. Find the mZP, 12 36° 140" 144"

bogdanovich [222]

m∠P = 144°

Solution:

PQRS is a parallelogram.

m∠P = 12a°, m∠Q = (4a - 12)° and m∠S = 3a°

In parallelogram, opposite angles are congruent.

m∠Q = m∠S

4a° - 12° = 3a°

Add 12° on both sides.

4a° - 12° + 12° = 3a° + 12°

4a° = 3a° + 12°

Subtract 3a° on both sides.

4a° - 3a° = 3a° + 12° - 3a°

a° = 12°

To find the measure of angle P:

m∠P = 12a°

= 12(12°)

m∠P = 144°
