Answer:
Step-by-step explanation:
Let the original water level is x.
<u>Use below equation to find its value:</u>
- x + 2.4 + 3 1/2 = 162 + 14.6
- x + 2.4 + 3.5 = 176.6
- x + 5.9 = 176.6
- x = 176.6 - 5.9
- x = 170.7 cm
Answer:
100
Step-by-step explanation:
sum the parts of the ratio, 4 + 5 + 1 = 10 parts
Fiona gets 40 sweets which is 4 parts of the ratio
Divide Fiona's share by 4 to find the value of one part of the ratio
40 ÷ 4 = 10 ← 1 part of the ratio
The total number of sweets is 10 parts , thus
number of sweets in total = 10 × 10 = 100
Answer:
y=x,y=12x+1
y=4x+4,y=6x
y=x+1,y=x+4
Step-by-step explanation:
Answer:
option (A) 62 miles
Step-by-step explanation:
Data provided in the question:
Ratio on the left = 434 miles : 14 gallons
ratio on the right = ?? : 2 gallons
Now,
The ratio on the both sides are equal
let the unknown value in the ratio be 'x'
Now, the ratio a : b can also be represented as 
therefore,
434 miles : 14 gallons = x : 2 gallons
or
⇒
=
or
⇒ x =
or
⇒ x = 62 miles
Hence,
the correct answer is option (A) 62 miles
Answer:

Step-by-step explanation:
Given



Find the length of HG
First, it should be noted that the displayed figure is a trapezium
<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>
In this case;

Substitute the values of Area, HE and EF


Divide both sides by 4


Subtract 12 from both sides



<em>Hence, the length of HG is 5mm</em>
