80% of what number is 15? Round the answer to the nearest tenth
Answer:
x = 18.75 Round to nearest tenth is 18.8
Step-by-step explanation:
We have, 80% × x = 15
or, [tex]\frac{80}{100}[/tex] × x = 15
Multiplying both sides by 100 and dividing both sides by 80,
we have x = 15 × [tex]\frac{100}{80}[/tex]
x = 18.75
If you are using a calculator, simply enter 15×100÷80, which will give you the answer.

a square has congruent sides so we can /4 to get each side when we are given the perimeter in such question.
28/4 = 7cm each side
area = L X W
= 7 x 7 = 49 cm^2
Given the function f(x) = x - 1. evaluate f(-12).
Answer:
f(-12) = -13
Step-by-step explanation:
f(x) = x - 1
Let x = -12
f(-12) = -12-1
= -13
Answer:
[tex]f(x) = x - 1 \\ f( - 12) = - 12 - 1 \\ \boxed{ f( - 12) = - 13}[/tex]
f(-12) = -13 is the right answer.Anyone know how to do this?

Have a blessed day
The difference between the high temperature and the low temperature is 24.3 F.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the high temperature was recorded as 19.8°F. The low temperature that same day was recorded as −4.5°F.
The difference will be calculated as,
D = High temperature - low temperature
D = 19.8 - (-4.5)
D = 24.3 F
Therefore, the difference between the high temperature and the low temperature is 24.3 F.

Write an INEQUALITY that represents the sentence
1) The sum of a number and 5 is less than 7
2) The product of a number and 8 is at least 25
3) Six less than a number is greater than 54
4) the quotient of a number and 12 is no more than 6
Answer:
Step-by-step explanation:
Let n represent the unknown number.
1) The sum of a number and 5 is less than 7 becomes n + 5 < 7
2) The product of a number and 8 is at least 25 becomes 8n ≥ 25
3) Six less than a number is greater than 54 becomes n - 6 > 54
4) the quotient of a number and 12 is no more than 6 becomes n/12 ≤ 6
1. The cost of 4 hates is $29.68. What is the unit price?
2. Jess types 625 words in 6 minutes. How many words can Jess type per minute?
To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.
1. 29.68 / 4 = 7.42
So $7.42 is the unit price.
2. 625 / 6 = 104 (rounded to the nearest whole number)
So Jess can type 104 words per minute.
Answer:
1. 7.24
2. 104
Step-by-step explanation:
1. divide 29.68 by 4
> 29.68÷4
> 7.24
therefore the unit price is 7.24
check: 7.24x4=29.68
2. divide 625÷6
> 625÷6
> 104.1666667
> 104.1666667 round off 104
therefore he can type 104words per minute

Answer:
rearrange the question
y - 5x = 8.................(1)
y - 8x = 9..................(2)
make y the subject formula in eqn. (1)
y = 8 + 5x................(3)

-3x = 1
x = -⅓
y = 8 + 5x

The shape of a glass stopper is composed of a hemisphere of radius 3 cm and a right circular cone with a slant height of 5 cm as shown. Find the total surface area of the glass stopper. (Take 3.14)
Answer:
Total Surface Area = 150.72 cmStep-by-step explanation:
Surface Area of a cylinder = 2 × area of base + lateral face
First find the area of the base
Area of Base = πr² ( pi × radius squared ) ( pi = 3.14 )
AB = 3.14 × 3²
AB = 3.14 × 9
Area of Base = 28.26
Next, find the lateral face
Lateral Face = circumference of base × altitude
( circumference of base = 2πr ) ( altitude = height of the cylinder )
LF = 2 × 3.14 × 3
Lateral Face = 18.84
Last, is the Surface Area
Surface Area of a cylinder = 2 × area of base + lateral face (formula)
SA = 2 × 28.26 + 18.84 × 5
SA = 56.52 + 18.84 × 5
SA = 56.52 + 94.2
Total Surface Area = 150.72
