i need to find the area .
Answer:
105.12 ft^2
Step-by-step explanation:
Area of rectangle = 8 × 10 = 80 ft^2
Area of semicircle = 1/2π × 4^2
4 is the radius of the semicircle.
Since we use 3.14 to approximate π...
Area of semicircle = 1/2× 3.14 × 4^2 = 25.12
∴Total area = 25.12 + 80 = 105.12 ft^2
Answer: 105.12ft²
Step-by-step explanation: first we need to find the area of the rectangle with the formula: length × width so, 8ft × 10ft = 80 ft².
Now we can find the area of the semicircle with the formula: πr²÷ 2 so, (3.14 × 4²) ÷ 2 = 25.12ft². Now we need to calculate the area of the whole shape and we can do this by adding together our rectangle and semicircle so, 80ft + 25.12ft = 105.12ft².

Sarah's gross income last month was £1260.
She pays 20% tax on her gross income.
How much tax did Sarah pay last month?
ایا
Answer: 252
Step-by-step explanation:
The amount of tax paid by Sarah last month is £252.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Sarah's gross income last month was £1260. She pays 20% tax on her gross income.
The tax amount is calculated by taking 20% of the gross income £1260.
Tax amount = 20% of £1260.
Tax amount = £1260 x 20 /100
Tax amount = £1260 / 5
Tax amount =£252.
Therefore, the amount of tax paid by Sarah last month is £252.

is {(3,4),(3,5),(4,4), (4,5)} a function
Answer:
No, it's not a function.
Step-by-step explanation:
This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. Therefore, this is not a function.
Answer:
This is NOT a function because you CANNOT have same x values twice.

1. Express 53 pm, the size of a hydrogen atom, in scientific notation
Answer:
[tex]5.3\times 10^{-11}\ m[/tex]
Step-by-step explanation:
In this problem, we need to express 53 pm in which is the size of a hydrogen atom, in scientific notation.
Any number can be expressed in scientific notation as follows :
[tex]N=a\times 10^b[/tex]
a is any real no and b is any integer
We know that, 1 pm = [tex]10^{-12}\ m[/tex]
It means, [tex]53\ pm=53\times 10^{-12}\ m[/tex]
or
[tex]53\times 10^{-12}\ m=\dfrac{53}{10}\times 10^{-12}\times 10\\\\=5.3\times 10^{-12+1}\\\\=5.3\times 10^{-11}\ m[/tex]
Therefore, the above is the scientific notation for the size of a hydrogen atom.

What are each of the steps on solving 5x-2+ 3x=14. There are four steps and the choices are combine like terms, addition, subtraction, division, and distribution.
Answer:
5x - 2 = 3x = 14
8x -2 = 14
8x = 14 + 2
8x = 16
x = 2
Step-by-step explanation:
Answer:
add 5x and 3x then add -2 to 14. it should be 8x=12 then divide 8x and 12 by 8 and its 12/8 or simplify to 6/4 or 1 1/2 so combine like terms then addition then division i think :)

Priya drew a triangle with the side lengths 3, 4, 5. She wants to draw a triangle that is a SMALLER scaled copy. Which of the following are scale factors she could use to make the triangle smaller?
Answer:
She could make the triangle smaller by making the same triangle but smaller and add the same sides to the small triangle.
scale factors she could use to make the triangle smaller is [tex]\frac{1}{2}[/tex]
Given :
Priya drew a triangle with the side lengths 3, 4, 5
Given options are :
1.) 1/2
2.) 1
3.) 2
4.) 6
Explanation :
The ratio of the measurement of the corresponding sides of a triangle is a scale factor .
When we multiply the side length by a scale factor >1 that gives a bigger scaled copy
When we multiply the side length by a scale factor <1 that gives a smaller scaled copy
From the given options , scale factor 1/2 is less than 1
So 1/2 is the scale factor that could use to make the triangle smaller

In the previous problem, Ken predicted a drop in
temperature. Explain why a drop in temperature would
lead to adding a negative integer.
Answer:
Because a drop in temperature means decrease in temperature therefore, we take an integer with negative sign and added to previous temperature.
Step-by-step explanation:
Drop in temperature means decrease in the temperature .When the temperature decreases then we take decrease value of temperature in negative integer. Because decrease means the temperature fall down .Hence , the decrease in temperature measure with negative sign .
For example, if we take temperature T= 70°C.
If the temperature decreases by 5°c then the temperature
Decrease in temperature=-5°C
Hence, the temperature T= 70+(-5)=65°C.
Therefore , from example we can say that when temperature decreases by some value in integer . Then ,we get final temperature obtained by adding drop in temperature ( negative integer ) in previous value of the temperature.
Answer: Sample reasopnse
A drop in temperature means the temperature will decrease. That decrease is represented by a negative integer, which should be added to the previous temperature.

as a fraction
To convert the decimal 0.36 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
0.36 = 0.36
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,
0.36
1
= (0.36 × 100)
(1 × 100)
= 36
100
.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(36,100) = 4. So,
(36÷4)/(100÷4)
= 9

ABC is a triangle in which B = 90°. In each of
these, i draw and label a sketch, ii then calculate
b
the length of the third side of the triangle.
AB = 6 m, BC = 8 m
Step-by-step explanation:
You have to use pythagoras' theorem for this.
So AC is the length you want to find.
Pythagoras' theorem is a^2+b^2=c^2
In your triangle, AB=a, BC=b and AC=c
6^2+8^2=Ac^2
36+64= AC^2
100=AC^2
Square root both sides
10=AC
Therefore AC=10m
The sum of one-third a number and twenty-five is as much as twice the number
Answer:
75/7 = 105/7 (ten whole number, five over seven)
Step-by-step explanation:
1/3n + 25 = 2n
n is the number
n/3 + 25/1 = 2n
n + 75/3 = 2n
cross multiply
n + 75 = 6n
75 = 7n
n = 75/7
n = ten whole number, five over seven (105/7)
