Answer:
31
Step-by-step explanation:
32 - x = 1, so we do this. 32 - 1 = x. So we get 31.
Answer:
c
Step-by-step explanation:
Answer:
The value of x = 20.05
Step-by-step explanation:
As we know that the sum of the angles in a triangle is 180°.
From the diagram, we can say that the sum of the angles A, B, and C must be 180°.
so the equation of the sum of the angles of a triangle will be:
As
Substituting the values in the equation of the sum of the angles of a triangle to find the value of x.
∵
Subtract from both sides
Therefore, the value of x = 20.05
VERIFICATION:
1 3/4 oz is mixed with 1 gallon of water. With 5 2/5 gallons of water, since we multiplied the number of gallons by 5 2/5, we multiply the amount of chemical by 5 2/5 as well:
1 3/4 * 5 2/5
Convert to improper fractions:
7/4 * 27/5 (because 1*4+3=7 and 5*5+2=27)
189/20 = 9 9/20 (because 20 goes into 189 9 times with 9 left over)
Answer:
A₁ = 950 mm²
Step-by-step explanation:
region 1 is a trapezium with area (A₁ ) calculated as
A₁ = h (b₁ + b₂)
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 38 , b₁ = 30 and b₂ = 20 , then
A₁ = × 38 × (30 + 20) = 19 × 50 = 950 mm²
