Can you take a better picture and I will help?
<u>Given: </u>
- Breadth of canvas is 22 inches.
- Length of canvas is 38 inches.
<u>To Find:</u>
- If kendra covered 30% of the canvas by painting red rose, what will be the area of canvas covered by red rose?
<u>Solution: </u>
To find the area of red rose, first we have to find the area of canvas.
★ Area of Rectangle = Length × Breadth
➝ 22 × 38
➝ 836 in²
So, Area of canvas is 836 inches².
★ Area of red rose:-
➝ 30% of 836 in²
➝ 0.30 of 836
➝ 250.8
Hence, Area covered by the red rose is <u>2</u><u>5</u><u>0</u><u>.</u><u>8</u>

★ Triangle => ½bh
★ Rectangle => Length × Breadth
★ Circle => πr²
★ Square => Side × Side
★ Parallelogram => Base × Height
★ Sphere => 4πr²
Answer:
D = K-10
Step-by-step explanation:
Let the number of games won by Dave's favourite basketball team be D and Kimiko's be K.
D + 10 = K
therefore,
D = K-10

Answer:
B. False. Within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population.
Step-by-step explanation:
In a stratified sample, each stratum should be proportional to that category of the population. This means that each stratum would potentially have a different number of elements in it.
Answer:
B - 150 yd
Step-by-step explanation:
Obviously the first step is to find the missing measurement. To do this, you use the Pythagorean theorem; <em>a² + b² = c².</em>
In this case, let's label the the missing side A, the height B, and the hypotenuse C.
<em>X² + 15² = 25²</em>
Then you must figure out what 15² and 25².
<em>15² = 225</em>
<em>25² = 625</em>
The next step is to subtract 15² (225) from 25² (625), which will give you the result of X².
<em>625 - 225 = 400. </em>
Now you know X² = 400, you can find the square root of 400 to give you the length of the triangle.
<em>√400 = 20.</em>
<u>The missing length of the triangle is 20 yards. </u>
Now it's just a matter of finding the area by using the formula;
<em>A = </em>
Or,
<em>(20 × 15) ÷ 2 = 150.</em>
<u>And there's your answer. Don't forget to add the units.</u>
