Answer:
43°
Step-by-step explanation:
<em>to </em><em>calculate</em><em> </em><em>this </em><em>angle </em><em>you </em><em>have </em><em>to </em><em>find </em><em>the </em><em>value</em><em> </em><em>of </em><em>angle </em><em>x </em><em>because</em><em> </em><em>the </em><em>two </em><em>are </em><em>equal</em><em> </em><em>since </em><em>they </em><em>originate </em><em>from </em><em>the </em><em>same </em><em>arc </em><em>to </em><em>find</em><em> </em><em>angle </em><em>y,</em><em>you </em><em>subtract</em><em> </em><em>the </em><em>sum </em><em>of </em><em>9</em><em>0</em><em> </em><em>and </em><em>4</em><em>7</em><em> </em><em>by </em><em>1</em><em>8</em><em>0</em><em>,</em><em> because</em><em> </em><em>they </em><em>form </em><em>a </em><em>triangle</em><em> and</em><em> </em><em>the </em><em>top </em><em>part </em><em>of </em><em>that </em><em>triangle</em><em> </em><em>is </em><em>9</em><em>0</em><em>°</em><em>(</em><em> </em><em>the </em><em>angle </em><em>at </em><em>the </em><em>circumference</em><em> </em><em>is </em><em>half</em><em> </em><em>the </em><em>angle</em><em> </em><em>at </em><em>the </em><em>center</em><em> </em><em>1</em><em>8</em><em>0</em><em>/</em><em>2</em><em>=</em><em>9</em><em>0</em><em>°</em><em>)</em>
<em>9</em><em>0</em><em>+</em><em>4</em><em>7</em><em>+</em><em>x=</em><em>1</em><em>8</em><em>0</em>
<em>x=</em><em>1</em><em>8</em><em>0</em><em>-</em><em>1</em><em>3</em><em>7</em>
<em>x=</em><em>4</em><em>3</em><em>°</em>
<em>therefore</em><em> </em><em>y=</em><em>4</em><em>3</em>

Answer: 39.5 ft^2
Step-by-step explanation:
1. Find the area of the rectangle using the formula length * width
2. Find the area of one of the triangles (the top one) using the formula 1/2(b*h)
3. Find the area of the other triangle (the bottom one) using the formula 1/2(b*h)
- 3 ft * 3 ft * 0.5 = 4.5 ft
4. Add 'em all up to get the total area
- 32 ft + 3 ft + 4.5 ft = 39.5 ft ^2
The result is <span>B. 1638.</span>
To calculate this, we will use both an addition and a multiplication rule. The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. <span>The multiplication rule calculates the probability that both of two events will occur.
First, there are two possibilities for winning exactly one match:
1. To win the first match and lose the second one.
2. To lose the first match and win the second one.
9% = 0.09 is the probability of winning. The probability of losing is 1-0.09 = 0.91. To calculate the probability of winning </span><span>the first match and losing the second one and vice versa, we will use the multiplication rule:
</span>1. 0.09 × 0.91 = 0.0819
2. 0.91 × 0.09 = 0.0819
We want to either one of these events to happen, so using the addition rule, we have:
0.0819 + 0.0819 = 0.1638
In 10,000 matches:
0.1638 × 10,000 = 1,638
Answer: 36
--------------------------------------------------------------------------------
Explanation:
There are 35 girls and 50 boys. Making 35+50 = 85 students total.
Of the 85 students, 42% (see column 1, bottom row) bought their lunch from the cafeteria. So 0.42*85 = 35.7 which rounds to 36
Answer:
Step-by-step explanation:
The price is x
50% of the price is $35
- x*0.5 = 35
- x = 35/0.5
- x = 70
Answer is $70
