Answer:
<h2>A = 37 cm²</h2>
Step-by-step explanation:
Look at the picture.
We have two rectangles:
15cm × 2cm and 7cm × 1cm.
Calculate the areas:
A₁ = 15 · 2 = 30 cm²
A₂ = 7 · 1 = 7 cm²
The area of the figure:
A = A₁ + A₂ → A = 30 cm² + 7 cm² = 37 cm²
Answer: 32 apples
Step-by-step explanation:
The ratio of apples to oranges sold is given as 4 to 2. Since Tia wants to sell a total of 48 apples and oranges, the number of apples that she should sell would be:
= 4/(4+2) × 48
= 4/6 × 48
= 32
Therefore, he should sell 32 apples.
I'm pretty sure it's 7 and 1/7
Answer:
1370
Step-by-step explanation:
<h3>Given</h3>
- AP with d= 7 and a₂₂ = 149
<h3>To find</h3>
<h3>Solution</h3>
<u>First, let's get the value of the first term:</u>
- aₙ = a + (n-1)d
- a₂₂ = a + 21d
- 149 = a + 21*7
- a = 149 - 147
- a= 2
<u>Next, let's find the sum of the first 20 terms</u>
- Sₙ = 1/2n(2a+ (n-1)d)
- S₂₀ = 1/2*20(2*2 + 19*7) = 10(4 + 133) = 10*137 = 1370
<u>Answer is</u> 1370
