How should I solve this? The answer is 31.9 cm²
Answers
Answer:
31.9 cm² (3 s.f.)
Step-by-step explanation:
[tex]\boxed{area \: of \: sector = \frac{θ}{360º} \times \pi {r}^{2} }[/tex]
∠AOD
= 360° -60° - 120° -45° (∠s at a pt.)
= 135°
Area of shape
[tex] = \frac{60°}{360°} (\pi)({2}^{2}) + \frac{120°}{360°} (\pi)(3^{2} )+ \frac{45°}{360°}(\pi)( 5 {}^{2}) + \frac{135°}{360°} (\pi)(3 {}^{2} )[/tex]
[tex] = \frac{1}{6} (4\pi) + \frac{1}{3} (9\pi) + \frac{1}{8} (25\pi) + \frac{3}{8} (9\pi)[/tex]
[tex] = \frac{4}{6} \pi + \frac{9}{3} \pi + \frac{25}{8} \pi + \frac{27}{8} \pi[/tex]

Solve for X. 3/4x+7/8=4 1/4 Enter your answer as a mixed number in simplest form in the box.
Answers
Step-by-step explanation:
[tex] \frac{3}{4} x + \frac{7}{8} = 4 \frac{1}{4} [/tex]
[tex] \frac{3}{4} x = \frac{17}{4} - \frac{7}{8} [/tex]

The value of x in the expression (3/4)x+7/8 = 17/4 is 9/2.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, (3/4)x+7/8 = 17/4.
Now to get rid of the denominator LCM of 4 and 8 is 8 so we'll multiply each term by 8.
6x + 7 = 34.
6x = 27.
2x = 9.
x = 9/2.

which distance is longer 500 kilometers or 250 miles explain
Answers
Can u give me a brainliest answer???
1 mile = 1,609344 km
250 miles = X
X= 250 x 1,609344
X= 402,336km
So 500 km > 250 miles
The measurement of 500 km is greater than 250 miles
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
To compare the distances, we need to convert one of them to the same unit as the other. One kilometer is approximately equal to 0.621 miles, so we can convert 500 kilometers to miles:
From the unit conversion , we get
1 km = 0.621 miles
500 kilometers = 500 x 0.621 = 310.68 miles (rounded to two decimal places)
Now we can compare distances 310.68 miles to 250 miles. Since 310.68 miles is greater than 250 miles, we can conclude that 500 kilometers is a longer distance than 250 miles.

Step-by-step explanation:
We can rearrange the equation for y-intercept form:

4y=-3x-12
y=-3/4x-3
The perpendicular equation would have an inverse slope, so we flip -3/4
y = 4/3x -3
