Answer:

The area of the base B is equal to 770\ cm^{2}

The volume  is equal to 10,087\ cm^{3}

Step-by-step explanation:

I will proceed to resolve the problem indicated in the attached figure.

The figure shown a inverted rectangular pyramid

The base is a rectangle

The area of the base B is equal to

B=(35)(22)=770\ cm^{2}

To find how many cubic centimeters of titanium are needed to manufacture one tip, calculate the volume of the figure

<em>Find the volume of the inverted rectangular pyramid</em>

The volume of the pyramid is equal to

V=\frac{1}{3}BH

we have

B=770\ cm^{2}

H=39.3\ cm

substitute

V=\frac{1}{3}(770)(39.3)=10,087\ cm^{3}

schepotkina [342]

Given:

In an office, there are 75 women and 125 men.

To find:

The ratio of the number of men to the number of women.

Solution:

We have,

Number of men = 125

Number of women = 75

The ratio of the number of men to the number of women is:

\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}

\text{Required Ratio}=\dfrac{125}{75}

\text{Required Ratio}=\dfrac{5}{3}

\text{Required Ratio}=5:3

Therefore, the ratio of the number of men to the number of women is 5:3.

In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
luda_lava [24]

Hello, I Am BrotherEye

Answer:

27.92 units

Step-by-step explanation:

Radius (qr) = r = 16 units

<QŘS = θ = 82°

Length of an arc = (Θ / 360) * 2πr

L = (θ / 360) *2πr

L = (82 / 360) * 2π * 16

L = 0.2777 * 100.53

L = 27.917 units

L = 27.92 unit

Best Of Luck
