A because you can go into the numbers evenly
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
it is important to note that 40/8 = 5.
A real number is one that can be found on the number line, and 5 can be.
A rational number can be made by dividing two integers (40 by 8 in this case).
5 is a whole number since it does not have a decimal/fractional part
an integer is a whole number which is positive/negative (5 is positive in this case)

which best describes this equation
10+6 x=15+9 x-3 x
a one real solution
b the solution is 0
c no real solutions
d an infinite number of solutions
Answer:
c. no real solutions
Step-by-step explanation:
because:
1. 10+6x=15+9x-3x
6x+10=15+9x-3x
2. 6x+10=15+9x-3x
6x+10=15+6x
3. 6x+10=15+6x
6x+10=6x+15
4. 6x+10=6x+15
6x+10-10=6x+15-10
5. 6x=6x+5
6. 6x=6x+5
6x-6x=6x+5-6x
Then you get:
0=5
remember, If you want to know if an equation has no equation:
the constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur. Use distributive property on the right side first.
I hope this helps :)
Help me on this please, giving more points than usual for this.
Answer:
the angle is = 50
Step-by-step explanation:
8x+2+70+60=180° (interior angles of a triangle add up to 180°)
8x+132=180
8x=180-132
8x=48
divide with the coefficient of x both sides
x=6
substitute
(8(6)+2)+70+60=180
50+70+60=180
180=180
are the triangles below similar? yes or no?
Answer:
Yes. They all have the same angle measurements making them similar.
Find the complementary angles of the following.
Answer:
37 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Complementary means 90 degrees. So, we would do 90 - 52.5 = 37.5 or 37 1/2

Answer:
Here is the step: Area of triangle = 1/2 (height x base) = 1/2 (9 x 18) = 81
Step-by-step explanation:
Then the Area of the rectangular = 12 x 18 = 216
So the total Area of the figure is = 81 + 216 = 297

What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
400 raffle tickets were sold for $4 each.
The one first prize winner will receive $300, and two people will each receive a second prize of $200.
There will be three $100 winners.
First prize = $300
Second prize = 200 x 2
=$400
So, the expected gross winnings:
3x100=$300
300+400+300
=$1000

50 55 60 65 70 75 80 85 90 95 100
A The highest score was obtained in Ms. Ricks' second period class.
B The lowest score was obtained in Ms. Ricks' first period class.
C The Interquartile Range (IQR) is higher in Ms. Ricks' first period class.
D The Interquartile Range (IQR) is higher in Ms. Ricks' second period class.
EMs. Ricks' first period scored better overall than second period.
F Ms. Ricks' second period scored better overall than first period.
Answer:
B and c and also f is the answer
1st Period: Minimum = 60, Lower Quartile = 75, Median = 80, Upper Quartile = 90, Maximum = 98
* Range = 98-60 = 38; *Interquartile Range = 90-75 = 15
2nd Period: Minimum = 70, Lower Quartile = 80, Median = 85, Upper Quartile = 91, Maximum = 95
* Range = 95-70 = 25; *Interquartile Range = 91-70= 21
Correct Answers: B, C, F
B - lowest score was a 60 in first period
C - IQR in 2nd period is 21, which is higher than 15 in first period
F - Approximately 75% (Q1-Q3) of first period scores are higher than 75% (Q1-Q3) of second period.
Correct answers are :-
B - lowest score was a 60 in first period
C - IQR in 2nd period is 21, which is higher than 15 in first period
F - Approximately 75% (Q1-Q3) of first period scores are higher than 75% (Q1-Q3) of second period.
What is statistics?The practice or science of collecting and analysing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample.
1st Period: Minimum = 60, Lower Quartile = 75, Median = 80, Upper Quartile = 90, Maximum = 98
* Range = 98-60 = 38; *Interquartile Range = 90-75 = 15
2nd Period: Minimum = 70, Lower Quartile = 80, Median = 85, Upper Quartile = 91, Maximum = 95
* Range = 95-70 = 25; *Interquartile Range = 91-70= 21
Hence the solutions are:-
B - lowest score was a 60 in first period
C - IQR in 2nd period is 21, which is higher than 15 in first period

Randy drew a rectangle inside another with the size shown below on a piece of paper. He places the paper outside during a light rain. What is the approximate probability that a raindrop that lands on the paper will fall outside the shaded region?
Answer:
[tex]Probability = 84\%[/tex]
Step-by-step explanation:
First, calculate both areas
[tex]Area = Length * Width[/tex]
The area of the outer rectangle is:
[tex]Big\ Area = 20 * 25[/tex]
[tex]Big\ Area = 500cm^2[/tex]
The area of the small rectangle is:
[tex]Small\ Area = 10 * 8[/tex]
[tex]Small\ Area = 80cm^2[/tex]
The area outside the small rectangle is:
[tex]Outside = Big - Small[/tex]
[tex]Outside = 500cm^2 - 80cm^2[/tex]
[tex]Outside = 420cm^2[/tex]
So, the probability that it falls outside the paper inside is:
[tex]Probability = \frac{Outside}{Big\ Area}[/tex]
[tex]Probability = \frac{420cm^2}{500cm^2}[/tex]
[tex]Probability = \frac{420}{500}[/tex]
[tex]Probability = 0.84[/tex]
Express as percentage:
[tex]Probability = 0.84*100\%[/tex]
[tex]Probability = 84\%[/tex]

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble. Each small bubble has a radius of 5 centimeters. What is the radius of the large bubble?
find area of 1 small bubble
πr² = π × 5²
= 78.54
total area of 4 small bubble
78.54 × 4 = 314.16
total area of 4 small bubble = area of big bubble
= 314.16
find it's radius
πr² = 314.16
r² = 314.16 ÷ π
r² = 100
r = √100
r = 10
Answer:
AREA OF LARGE BUBBLE=PI×R^2
AREA OF 1 SMALL BUBBLE =PI×r^2
then area of 4 small bubble =(PI×r^2)×4
now,
area of large bubble =area of 4 small bubble
PI×R^2=4×(PI×r^2)
R= 10 cm
