The end of a house has the shape of a square surmounted by an equilateral triangle. If the length of the base is measured to be

sergij07 [2.7K]

Answer:

The area of the end is 1755.44 ft²

Therefore, the maximum error in calculating area of the end is 8.3592

Step-by-step explanation:

Consider the provided information.

The length of the base is measured to be 35 feet, with a maximum error in measurement of 1 inch,

$1\ inch = \frac{1}{12}\ feet$

The area of shape = Area of square + Area of equilateral triangle

$A=x^2+\frac{\sqrt{3}}{4}x^2$

Substitute x=35 in above.

$A=(35)^2+\frac{\sqrt{3}}{2}\times (35)^2=1755.44$

Hence, the area of the end is 1755.44 ft²

Differentiate $A=x^2(1+\frac{\sqrt{3}}{4})$ with respect to x as shown:

$dA=2x\ dx(1+\frac{\sqrt{3}}{4})$

Substitute dx =1/12 and x=35

$dA=2(35)\ \frac{1}{12}(1+\frac{\sqrt{3}}{4})=8.3592$

Therefore, the maximum error in calculating area of the end is 8.3592

What is the value of x? A.86 B.60 C.52 D.26

Nadya [2.5K]

First of all in order for us to figure out what angle x is we need to find the formula for finding that specific type of angle.

Formula is...

x = (far arc - close arc) ÷ 2

Now we just need to plug in.

x = (172° - 52°) ÷ 2 =

x = 120° ÷ 2 = 60°

Your answer: x = 60°

Good Luck! :)

Simplify<br> a)<br> a^5 divided by a^3

Ymorist [56]

The value simplified is <u>a²</u>

-

In a power division with equal bases - we subtract the exponents and keep the bases.

The representation of this expression in formula is given by:

$\large \sf a {}^{n} \div a {}^{m} = \boxed{ \large \sf a {}^{n - m} } \\ \\$

<h3>Resolution </h3>

$\large \sf a {}^{n} \div a {}^{m} = \boxed{ \large \sf a {}^{n - m} }$

$\large \sf a {}^{5} \div a {}^{3} = \purple{\boxed{ \large \sf a {}^{2} } } \\$

So, the answer of this expression is <u>a²</u>

Kamal sells 240 ice creams for a total of £640

Free_Kalibri [48]

Answer:

2.10

Step-by-step explanation:

# of large ice creams: 240/3 = 80

# of small ice creams: 240 - 80 = 160

Total large ice cream cost: 80*3.8 = 304

Total small ice cream cost: 640 - 304 = 336

Cost of one small ice cream: 336/160 = 2.1
