How do you evaluate fractions with whole numbers?
Multiply a fraction with a whole number by multiplying only the numerator. For example, 5 x 1/8 = 5/8. Multiply a fraction with another fraction by multiplying the numerators together and the denominators together. For example, 3/8 x 2/5 = 6/40 = 3/20.
please and thank you
Answer:
The answer is B
Step-by-step explanation:
You can turn them into improper fractions
so
[tex]10 \frac{1}{2} = \frac{21}{2} [/tex]
[tex]2 \frac{1}{4} = \frac{9}{4} [/tex]
when we divide we invert the second fraction
[tex] \frac{21}{2} \div \frac{9}{4} = \frac{21}{2} \times \frac{4}{9} [/tex]
now we can multiply as usual
[tex] \frac{21}{2} \times \frac{4}{9} = \frac{84}{18} [/tex]
[tex] \frac{84}{18} = \frac{14}{3} = 4 \frac{2}{3} [/tex]

Solve the equation for all values of x by completing the square.
x^2 + 6x – 27 = 0
Answer:
Solution
=3
=−9
x=3
x=−9
x=3x=−9
Step-by-step explanation:
Boom
Answer:
x=-9 and 3
Step-by-step explanation:
FOIL method
x^2+6x-27=0
Find the common numbers that multiply to 27 that will also equal 6.
(27x6) or (9x3)
the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.
then FOIL them
(x+9)(x-3)
FIRST: x*x=x^2
OUTSIDE: x*-3=-3x
INNER: 9*x=9x
LAST: +9*-3=-27
x^2(-3x9x)-27
x^2+6x-27
now that the equation matches you solve for x.
(x+9)=0 x=-9
(x-3)=0 x=3
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. What was the temperature:
1 hour ago?
3 hours ago?
Half an hour ago?
Answer:
For one hour ago, it would be 3 C, 3 hours ago, it would be 9 C, and half an hour ago, it would be 1.5 C.
Step-by-step explanation: It's quite straightforward. Since the temperature is dropping, and you want to find the temp. of earlier times, just add 3C to every hour (1.5 for a half) it was ago, to what the temperature currently is now. (0 C).

Abby is painting two cubes for an art project.
Cube 1: side length = 3 feet
Cube 2: side length = 2 feet
The surface area of a cube is 6s2, where s is the length of one side.
Find the total surface area that Abby will paint.
1. Find the surface area of cube 1. Show your work, and include units with your answer.
2. Find the surface area of cube 2. Show your work, and include units with your answer.
3. What is the total area Abby will paint?
Answer:
54 sq ft, 24 sq ft, 78 sq ft
Step-by-step explanation:
1. Each side of cube 1 is 3 feet x 3 feet, so each side has an area of 9 square feet. Multiply by 6 sides and the area is 54 square feet.
2. Each side is 2 feet x 2 feet so the area of one side is 4 square feet. Multiply by 6 sides and the area is 24 square feet.
3. 54 + 24 = 78 square feet

Answer:
Question no. 2 answer is A 100percent confrom
please explain and i will give brainly
Answer:
24 in.
Step-by-step explanation:
Because the radius would be half of the diameter, it would be 16/2 which is 8.
To find the area, you do pi times radius, so: 3*64=24.
The area would be 24in.

What is the absolute value? What symbol represents absolute value?
Answer:
Absolute value is the distance the number away is from 0. In simpler terms, if you had a -8 the absolute value is 8. I attached a picture of the absolute value symbols. The absolute value of a normal positive 8 is still 8 though because it's the same distance on a number line.

==========================================================
Explanation:
She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.
---------------------
For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)
|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.
---------------------
The last thing to do is find the mean of the set {10,4,1,4,11}
add: 10+4+1+4+11 = 30
divide by five: 30/5 = 6
The mean absolute deviation (MAD) is 6
This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.

What is the y-intercept of a line that has a Slope of 3 and passes through point (-1, -7)
Answers;
A. -10
B. -4
C. 3
D. 7
Answer:
B)-4
Step-by-step explanation:
y=mx+c
sub in a point and gradient/slope to get c
-7=3(-1)+c
-7=-3+c
-7+3=c
c=-4
y=3x-4
if u looking for the y intercept make x=0
y=3(0)-4
y=-4

of pineapple juice and the amount of
sparkling water proportional? Explain.
PART B
How much pineapple juice do Sylvia and
her friends need for this week’s punch?
18 quarts
12 quarts
6 quarts
3 quarts
Pineapple:Sparkling water
3:2

The approximate radius, r, of a circle with an area, A, is r=0.32^1/2.
Find the approximate radius of a circle with an area of 16 cm2.
Answer:
radius (r)= 2.25
Step-by-step explanation:
area (A)=16cm^2
A = πr^2
16= (22/7)r^2
(16*7)/22=r^2
√5.09= r
r=2.25
