Answer:
x = 30°
Step-by-step explanation:
Given that,
∠A = x°
∠B = 2x°
∠C = 90°
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°.
ATQ,
x° + 2x° + 90° = 180°
3x° = 180°-90°
3x° = 90°
x° = 30°
So, the value of x is 30°.
Answer:
y=3
Step-by-step explanation:
Assuming this is an enlargement where EFGH is enlarged to ABCD then the former is the object and the latter is the image. If so then
scale factor(k) of the enlargement=image length/corresponding object length
k=3/2
Therefore, y=4.5/k
y=4.5/(3/2)
y=3
If we take the assumption another way and say ABCD is reduced to EFGH then the former is the object and the latter is the image.
In that case,
k=⅔
y=4.5×k
y=3
In either case y=3units
Answer:
It would round down to 103 liters.
Step-by-step explanation:
3. (a)
Add the three totals.
Total sales for all three: $2030 + $1540 + $1800 = $5370
Now divide each person's sales by the total sales to find each person's fraction of the sales.
Lola: 2030/5370
Ahmed: 1540/5370
Tommy: 1800/5370
3. (b)
Multiply each fraction from part (a) by $100.
Lola: 2030/5370 * $100 = $37.80
Ahmed: 1540/5370 = $28.67
Tommy: 1800/5370 = $33.52
