Sam Houston's Arms
OLga [1]

Answer:

The length of the statue's arm is<u> 26.22 ft.</u>

Step-by-step explanation:

Let the length of the statue's arm be 'x'.

Given:

Height of statue is, H=67\ ft

Height of male is, h=5\ ft\ 9\ in=5\ ft+\frac{9}{12}\ ft=5+0.75=5.75\ ft

Length of the male's arm is, l=27\ in=\frac{27}{12}=2.25\ ft

Now, as the size of Sam Houston's statue is proportional to that of an adult male, therefore, their heights and arm lengths will also be in proportion. So,

\frac{H}{h}=\frac{x}{l}\\x=\frac{H}{h}\times l

Now, plug in the given values and solve for 'x'.

x=\frac{67}{5.75}\times 2.25\\x=26.22\ ft

Therefore, the length of the statue's arm is 26.22 ft

Answer: The mass of solid a is 4800 grams

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

For solid b = 40.32 cm2 / 6912 grams

For solid a = 28 cm2 / x grams

Where x is the mass of solid a.

So:  

40.32 / 6912 = 28 / x  

x = 28 / (40.32 / 6912)

x = 4800 grams

The mass of a is 4800 grams

ABCD is a rectangle. Its diagonals are AC and BD. If AC = 12cm, then BD = _______cm
defon

Answer:

BD = 12\ cm

Step-by-step explanation:

Given

Shape: Rectangle

Diagonals: AC and BD

AC = 12\ cm

Required

Determine BD

From the question, we understand that the shape is a rectangle and its diagonals are AC and BD

Every rectangle has 2 diagonals, both of which are equal.

This implies that:

BD = AC

Recall that:

AC = 12\ cm

Hence,

BD = 12\ cm

Please help!!! I'll mark you as BRAINLIEST and give you 10 points!!!!!
zheka24 [161]

Answer:

6

Step-by-step explanation:

Okay so the shape has an area of 60 square inches. The formula for the area of a triangle is A = b*h where A = area, b = base, and h = height

So we are given the value for A (60)

We are given the value for height (10)

So we just need to find the value of the base

So let's set this up as an equation. Input the given values into the area for triangle formula

A = B*h

60 = B * 10

So we need to solve for B. To do that we need to get B alone on one side of the = sign. B is being multiplied by 10 so do the opposite and divide both sides by 10

60 divided by 10 = 6

10 divided by 10 = 1 (don't actually put a 1 down, just drop it)

So we are left with

6 = B

So the base is 6 square inches. To test, put it in the equation:

A = B*h

60 = 6*10

60 = 60
