Find the Ares of a semi circle whose radius is 2.4 cm
Answer:
Step-by-step explanation:
area of semi circle=πr^2/2
=3.14*(2.4)^2/2
=3.14*5.76/2
=18.0864/2
=9.0432 cm^2
Answer:
72/25 [tex]\pi[/tex] cm² or 9.047786842... cm²
Step-by-step explanation:
Area of whole circle is [tex]\pi r^{2}[/tex]
[tex]\pi[/tex]×2.4² = 144/25[tex]\pi[/tex] cm² or 18.09557368... cm²
Since it is a semi-circle, divide this value by 2 (or multiply by 0.5, either way, your halving it):
144/25[tex]\pi[/tex] ÷ 2 = 72/25 [tex]\pi[/tex] cm² or 9.047786842... cm²
3y - 2 = 13 solve for y
Answer:
y = 5
Step-by-step explanation:
3y - 2 = 13
We are solving for y, so we want to isolate it.
Add 2 to both sides.
3y = 15
Continue isolating y by dividing both sides by 3.
y = 5
Check your answer by plugging it back into the original equation.
3y - 2 = 13
3(5) - 2 = 13
Multiply.
15 - 2 = 13
Subtract.
13 = 13
Your answer is correct.
Hope this helps!
Answer:
y = 5
Step-by-step explanation:
Get y by itself:
3y - 2 = 13
+2 +2
3y = 15
Divide by 3:
3y = 13
÷ 3 ÷ 3
y = 5

Answer:
16 units²
Step-by-step explanation:
Formula for the area of a parallelogram is given as, A = b*h
Where,
Base (b) = 4
Height (h) = √(5² - 3²) = 4 (Pythagorean theorem)
Plug in the values
Area of parallelogram, A = 4*4
= 16 units²

Find the range of the data.
The ages of people eating
chocolate ice cream at a park.
12, 2, 8, 5, 3, 2,5
Range: [? ]
Enter the number that belongs in the green box.
Answer:
range = 10
Step-by-step explanation:
The range is the difference between the largest and smallest values in the data set.
largest value = 12
smallest value = 2
range = 12 - 2 = 10

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
x = 39°
Step-by-step explanation:
51° + 90° = 141°
180° - 141° = x
x = 39°
They often don't label the 90° angle, so watch out for that in the future

Answer:
a. $1.50 per pound of weight.
b. C
Step-by-step explanation:
a. explanation:
1. pounds is increasing by +4 and dollars are increasing by +6.00
2. as a fraction it is 6/4.
3. simplified is 1 1/2 or 1.50
b. explanation
1. we know that the slope (or rate of change) is $1.50 /per pound of weight.
2. 4 - 4 = 0; $11.00 - 6.00 = $5.00
3. 0, $5.00
4. The y-int. is $5.00
5. answer is C
I need help with first question ??
Answer:
Slope = 3
Step-by-step explanation:
Slope formula
(y2 - y1) / ( x2 - x1)
Where the x and y values are derived from the coordinates
Choose any two given ordered pairs and plug them into the formula
The points chosen may vary but the points I chose were (1,3) and (2,6)
( Note that ordered pairs are written as (x,y))
Next we want to define the variables
x1 = 1
x2 = 2
y1 = 3
y2 = 6
Finally we plug in the values into the slope formula
(6-3) / (2-1)
Subtract top values
3/(2-1)
Subtract bottom values
3/1
Simplify
slope = 3
At Mike’s Pet shop there are 300 total animals and the ratio of cats to dogs is 7:3. At Pets R Us there are 150 total animals and the ratio of cats to dogs is 6:4. What fraction of the total animals at both stores are cats? Show your work
Mikes pet shop: add the ratio: 7+ 3 = 10
Divide total animals by the sum:
300/10 = 30
The ratio of cats is 7
Total cats = 30 x 7 =210
Do the same for Pets R Us:
Ratio: 6 + 4 = 10
150/10 = 15
Cats = 15 x 6 = 90
Total cats = 210 + 90 =300
Total animals = 300 + 150 = 450
Fraction that are cats = 300/450 = 2/3
2/3 of the animals are cats
Please, help!! Those are the steps that I have so far.

What is the length of the line?
Given that (1,4) is on the graph f(x), find the corresponding points of a function 1/4f(x)
Answer:
(1,1)
Step-by-step explanation:
In the equation f(x), you are plugging in the x coordinate which in this case is one. That means in 1/4f(x), x will remain the same, because you are still plugging in the same thing. What will change is the y coordinate. 1/4f(x) is saying that the y coordinate will be a fourth of the original y coordinate(4). 4 times 1/4 is equal to one.
If the x coordinate stays the same, and the y coordinate is a fourth of 4, the corresponding points in the function f(x) will be (1,1)

Miss Chambers bought 5 pens for $255, if she made a profit of $3 each per pen how much did she sell a pen for?
Answer:
$54
Step-by-step explanation:
First, we calculate the amount she paid for each pen.
$255/5 = $51
She paid $51 for each pen.
She made a profit of $3 per pen, so she sold each pen for $51 + $3 = $54
Answer: $54
