Answer:
70 square inches
Step-by-step explanation:
We have to find the area of the rectangle and this would help us determine how much paint he would need to paint his rectangle
Area of a rectangle = Length × Width
Length = 10 inches
Height = 7 inches
Area of the rectangle = 10inches × 7 inches
= 70 square inches
Therefore, he would be needing 70 square inches of paint in order to paint his rectangel
Answer:
35 × 2.5 × 2 = 175 /100
= 1.75
Step-by-step explanation:
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100.
Answer:
Step-by-step explanation:
In a right triangle only, the sine of an angle is equal to the angle's opposite side divided by the hypotenuse of the triangle. (o/h)
The cosine of the angle is equal to the angle's adjacent side divided by the hypotenuse of the triangle. (a/h)
The tangent of the angle is equal to angle's opposite side divided by the adjacent side. (o/a)
In this case, angle A's opposite side is 12, its adjacent side is 35, and the hypotenuse is 37 (o=12, a=35, h=37).
Thus we have:
Answer: y = 2.1
Step-by-step explanation:
Considering the given triangle XYZ, to determine side y, we would apply the sine rule. It is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes
x/SinX = y/SinY = z/SinZ
Therefore
y/Sin 15 = 8/Sin 94
Cross multiplying, it becomes
ySin94 = 8Sin15
0.998y = 8 × 0.259
0.998y = 2.072
y = 2.072/0.998
y = 2.1
The decimal will move to the left(making the number smaller) if multiplied by a negative integer power of 10.
