Answer:
77
Step-by-step explanation:
The area of 14 and 5.5 is 77 because 14 x 5.5 = 77. You are multiplying the 2 diameters to get the area.
Answer:
£168
Step-by-step explanation:
Amount to be shared = 560
Roshana's share = x
Nima's share = 3x
Kate's share = 2 * 3x = 6x
X + 3x + 6x = 560
10x = 560
x = 560 / 10
x = 56
Nima's share = 3x
Nima's share = 3* 56 = £168
Answer:
C. a quantity used as a standard measurement
Step-by-step explanation:
A unit is a universally acceptable system of measurement. The system is majorly referred to as the international standard of units i.e (SI) units.
Since physical quantities could be categorize as either fundamental or derived. The use of units in measurement is very essential, because it relates the magnitude measured to the physical quantity.
The units of measurement tells what physical quantity has been measured.
Answer:
f=1/25x
f=4/5f (simplified)
x=1/25f
x=4/5x (simplified)
Step-by-step explanation:
To solve for f.
fx=5−2
Step 1: Divide both sides by x.
fx/x=1/25/x
f=1/25x
To solve for x
fx=5−2
Step 1: Divide both sides by f.
fx/f=1/25/f
x=1/25f
Answer:
a. 0.69x + 0.14
b. 5.67 - 30.48a
c. 1.1x - 3.01y
Step-by-step explanation:
a) 2.56x + 0.14 − 1.87x
<em>To simplify this algebraic expression, you start by collecting like terms;</em>
2.56x − 1.87x + 0.14
<em>Then perform arithmetic operation</em>
0.69x + 0.14
b) 7.32a + 2.1 (2.7 − 18a)
<em>Here; first, the bracket must be opened</em>
<em>To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with</em>
7.32a + 2.1 * 2.7 − 2.1 * 18a
7.32a + 5.67 - 37.8a
<em>Then, you collect like terms</em>
7.32a - 37.8a + 5.67
<em>Then perform arithmetic operation</em>
-30.48a + 5.67
<em>Rearrange</em>
5.67 - 30.48a
c) 0.12x + 0.34y + 0.98x − 3.35y
<em>Here, you start by collecting like terms</em>
0.12x + 0.98x + 0.34y − 3.35y
<em>Then perform arithmetic operation</em>
1.1x - 3.01y
