Answer:
look at explanation, oh and pls give brainlist
Step-by-step explanation:
3. 7:8 [tex]\7\frac{7}{8}[/tex] ,7 to 8
4. [tex]\frac{100 l}{40 w}[/tex], [tex]\frac{25}{10}[/tex], [tex]\frac{50}{20}[/tex]
5. [tex]\frac{2 hrs}{120 m}[/tex], unit rate= 60 miles per hour, [tex]\sqrt[2]{120}[/tex]=60
6. [tex]\sqrt[3]{900}[/tex]= 300, 300x3=900, unite rate= 300km per hour
7. [tex]\frac{50}{5}[/tex]=[tex]\frac{10\\}{1}[/tex], unit rate for Tim= $10 for 1 hour, [tex]\frac{24}{2}[/tex]=[tex]\frac{12}{1}[/tex], unit rate for Jane= $12 for 1 hour, Jane has the higher rate of pay.
8. [tex]\frac{65}{4}[/tex]=[tex]\frac{16.25}{1}[/tex] , [tex]\sqrt[4]{65}[/tex]= 16.25, unit rate for Jon is 16.25ths of a pushup per minute.
[tex]\frac{45}{3}[/tex]=[tex]\frac{15}{1}[/tex], [tex]\sqrt[3]{45}[/tex]=15, unit rate for Paul is 15 pushups per minute.
Jon can do more pushups in 1 minute

Carol bought 2 pairs of jeans at 24 each and 3 shirts she spent a total of 75 before tax what is the cost of 1 shirt
A.$8
B.$17
C.$9
Answers
Answer:$9
Step-by-step explanation:Here's what we know:
2 * 24 + 3s = 75 (the pants ($24 each) and shirts all together is $75)
What we need to do is isolate s
Simplify:
48 + 3s = 75
subtract 48 from both sides:
48 + 3s - 48 = 75 - 48
3s = 27
Divide by 3:
3s / 3 = 27 / 3
s = 9
Shirts are $9 each.
Answer:
2 x 24 = 48
48 - 75 = 27
27 ➗ 3 = 9
so the cost of 1 shirt is $9

The answer should be...
[tex]117 mm^3[/tex](if your supposed to do volume)
[tex]174mm^2[/tex](if your supposed to do surface area)
Step-by-step explanation:
volume:
3 x 3 x 3 = 27
10 x 3 x 3 = 90
27 + 90 = 117
surface area:
3 x 3 x 2 = 18
3 x 3 x 2 = 18
3 x 3 = 9
3 x 10 x 2 = 60
3 x 10 x 2 = 60
3 x 3 x 2 = 18
18 + 18 + 9 + 60 + 60 + 18 - 9 = 174

Find the area of this figure please
Answers
Answer:
A. 122cm^2
Step-by-step explanation:
We can find the area of this figure by finding the area of each rectangle, then combining the areas.
The formula for area of a rectangle is simple; the formula is length x width.
The first rectangle has side lengths of 12 and 6.
12 x 6 = 72.
The area of the first rectangle is 72 cm.
Now, for the second rectangle.
Formula: length x width
10 x 5 = 50
The area of the rectangle is 50 cm.
Now we add both areas.
50 + 72 = 122 cm.
Therefore, the area of the figure is 122 cm^2.
Mrs. Abner randomly chooses one boy and one girl to participate in a spelling bee. The probability that Alex is chosen from the boys is 0.08.
The probability that Jane is chosen from the girls is 0.14.
Which is closest to the probability that Alex and Jane are chosen for the spelling bee?
Answers
Answer:
The probability of Alex and Jane getting picked is 0.0112 or 1.12
Step-by-step explanation:
Ok, so the probability that Alex is picked is 0.08, then in order for jane to be picked it is another 0.14.
That means that we must figure out what 14% of 0.08 is 0.0112
0.0112 = 1.12%

Percent of change from 30 to 90?
Answers
Answer:
200
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
Answer:
200%
Step-by-step explanation:
The change (increase) is 60.
60, divided by the original value 30, comes out to 2.
Multiplying this result by 100% yields 200%
Use a graphical method to find estimates for the solutions of the simultaneous equations x^2 + y^2=2.25 y-x=1
NEED ASAP WILL MARK AS BRAINLIEST
Answers
Answer:
A) which graph represents the equation x^2 + y^2 = 2.25?
First, the general equation for a circle can be written as:
(x - a)^2 + (y - b)^2 = R^2
This is a circle of radius R centered in the point (a, b).
Then we can rewrite our equation as:
(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2
Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5
Then we can see that the correct one is graph C.
b) Now we want to solve the system:
x^2 + y^2 = 2.25
y - x = 1
graphically.
To do it we need to graph both equations and see in which points do they intersect.
We already have the first equation graphed, so we only need to also graph the linear equation:
y - x = 1
y = 1 + x
An example of this can be seen in the graph below:
There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)
