Answer:
15%
Step-by-step explanation:
You take the number of student in 8th grade that are on social media for more than an hour which gives you (12) and divide it by the total number of students (81).
12/81=0.148 repeating
You then round 0.148 repeating to 0.15 and then turn it into a percent by moving the decimal two places to the right.
A = 6x – 2
B = 4x + 48
Answer:
X=25
angle A=148
Step-by-step explanation:
since they are alternating angles
A=B
6x-2=4X+48
solve for X
6x-4x=48+2
2x=50
X=25
angle A= 148
Answer:
148

Find the circumference of a circle with an area of 1809.56 square centimeters
Answer:
150.8cm
Step-by-step explanation:
Area= π r²
make r subject of the formula
A = π r²
A/π= πr² (dividing both sides by π)
r²= A/ π
r =
[tex] \sqrt{ \frac{a}{\pi} } [/tex]
r=√(1809.56)/(π)
r=√576.0008
r≈24cm
:. circumference= 2π r
= 2× π × 24
=150.7964
≈150.8cm

Answer:
50.27 cm²Step-by-step explanation:
Shaded area is the difference in the areas of big and small circles.
Circle area formula: A = πr²A = π(5²) - π(3²) = π(25 - 9) = 16 π = 50.2654824574 ≈ 50.27cm²Answer:
area of shaded region
=π5²-π3²=50.2857142857cm²
Step-by-step explanation:
to find shaded region first find area of big circle and of small
subtract area of small circle from big circle.
Meg and Theo each thought of five numbers. Meg's first number was 0, and so was Theo's. Meg added 2 each time to get her other numbers, and Theo added 4 each time. Which statement correctly compares Theo and Meg'snumbers? A Each of Theo's numbers is 2 more than Meg's corresponding number, because Theo adds 2 more than Meg to get the next number. B Each of Theo's numbers is half of Meg's corresponding number, because Theo adds half as much as Meg to get the next number. C Each of Theo's numbers is 4 more than Meg's corresponding number, because Theo adds 4 each time to get the next number. D Each of Theo's numbers is double Meg's corresponding number, because Theo adds twice as much as Meg to get the next number.
Answer:
D. Each of Theo's numbers is double Meg's corresponding number, because Theo adds twice as much as Meg to get the next number.
Step-by-step explanation:
Meg = 0, 2, 4, 6, 8
Theo = 0, 4, 8, 12, 16
Second number of Theo is 4 which is double of 2 (Meg second number)
This applies to the third, fourth and fifth number of Theo
Therefore,
Each of Theo's numbers is double Meg's corresponding number, because Theo adds twice as much as Meg to get the next number.
One of the legs of a right triangle measures 1 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
3.9 cm
Step-by-step explanation:
One of the legs of a right triangle measures 1 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
We can solve the above question using Pythagoras Theorem
Hypotenuse ² = Opposite ² + Adjacent ²
From the above question
Hypotenuse = 4 cm
1 leg = Opposite = 1 cm
Other leg = Adjacent = x
Hence
4² = 1 ² + x²
x² = 4² - 1²
x = √ 16 - 1
x = √15
x = 3.8729833462 cm
Approximately to the nearest tenth = 3.9 cm
The measure of the other leg is 3.9 cm

PLS HELP ME PLS ASAP. I WILL GIVE U THE BRAINLIEST ANSWER PLS HELP NOWW!!!!!!
Step-by-step explanation:
since packages are similarsimilar packages. The ratio of the volumes is 8:125. Determine the dimensions of the bigger package. The dimensions of the smaller package are... Height= 45cm, Length= 80cm, and Width= 25cm.
Length of bigger package = 80×125/8=1250cm
Width of bigger package =25×125/8=390.625cm
Height of bigger package =45×125/8=703.125cm

Answer: I used the Pythagorean theorem and got 6.24, but if I was supposed to use another method, just let me know.
The formula is a^2+b^2=c^2
a=5
c=8
b=?
5^2+b^2=8^2
25+b^2=64
b^2=39
b=6.24,
(If it doesn't work, put x=6.24, x=-6.24. It can be both technically, but most teachers ask only for the first one. )
Find the slope of the line. Write your answer in simplest form.
Answer:
Slope = -3/5
Step-by-step explanation:
slope (m) = y2 - y1 / x2 - x1
m = -2 - 1 / 1 - -4
m = -3 / 1 + 4
m = -3 / 5
You can check the work by counting rise (-3 which means 3 units down) over run (5 which means 5 units to the right)
Answer:
-3/5
Step-by-step explanation:
The line is y=-3/5x-1.4

HELP ME PLZ 20 POINTS AND BRAINLIEST
Answer:
35.9 units cubed
Step-by-step explanation:
Hello There!
The figure shown is a rectangular prism
The formula for volume of a rectangular prism is
Length times width times height
The dimensions for the shown figure are given
height = 4 1/2
length = 2 1/8
width = 3 3/4
given this information we just plug it in to the formula
so
[tex]V=3\frac{3}{4}*4\frac{1}{2} *2\frac{1}{8}[/tex]
then we plug it in to a calculator and get that the volume is equal to
35.859375
finally we round to the nearest tenth and get that the volume is equal to
35.9 units cubed
Angle K measures 67º and angle L measures 119°.
Circle O is inscribed by quadrilateral L M N K.
What are the measures of angles M and N?
m Angle M = 61o and m Angle N = 113o
m Angle M = 67o and m Angle N = 119o
m Angle M = 113o and m Angle N = 61o
m Angle M = 119o and m Angle N = 67o
Answer:
C. m Angle M = 113o and m Angle N = 61o
Step-by-step explanation:
It's the only answer that makes all the angles added together equal 360 degrees.
67 + 119 + 113 + 61 = 360
Answer:
C

What is the measure of angle A?
Answer:
∠ A = 35°
Step-by-step explanation:
The measure of the tangent- tangent angle A is half the difference of the intercepted arcs.
minor arc = 145°
major arc = 360° - 145° = 215°
Then
∠ A = [tex]\frac{1}{2}[/tex] ( 215 - 145) = [tex]\frac{1}{2}[/tex] × 70° = 35°

78 is 65% of what number (can someone explain how to solve this?)
Answer:
120
Step-by-step explanation:
78 is 65% of what number.
Let's break down this expression.
In this case "is" means "equals" so we will use the equal sign (=)
65% can be written as 0.65 or 65/100
"of" indicates multiplication
"what number" will be represented by x.
Now, put this all together.
78 = 0.65 • x
To solve for x, divide both sides by 0.65
120 = x
This is your answer.
Check this by finding 65% of 120.
0.65 • 120 = 78
Your answer is correct.
Hope this helps!
