Answer:
1/2
Step-by-step explanation:
There are 6 possible outcomes
1, 2, 3, 4, 5 and 6
3 of which are even numbers
So if you were to roll the cube there is a 3 in 6 ( 1/2 when simplified ) chance of it landing on an even number
Can someone help me with this question?
Answer:
A = 20.25 sq units
Step-by-step explanation:
to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it
it appears the segment is 4.5 units so you would square that to get the area
A = 4.5²
A = 20.25

Help please I don't really understand what to do here, so if somebody could find the answer that'd be great!
Answer:
See below.
Step-by-step explanation:
4.2 is 4 and 2 tenths.
4 is 40 tenths.
That means that 4.2 is 40 tenths plus 2 tenths, or 42 tenths.
First line: 4.2 / 6 = 42 tenths / 6
In the second line, we divide 42 tenths by 6. Since 42 divided by 6 = 7, then 42 tenths divided by 6 equals 7 tenths.
Second line: 4.2 / 6 = 7 tenths
In the third line, we write 7 tenths as a number. 7 tenths is the same as 0.7.
Third line: 4.2 / 6 = 0.7

5, 17, 17, 7, 12, 16, 12
Send data to calculator
Find the mean number of movies that the students saw.
If necessary, round your answer to the nearest tenth.

Answer:
mean=12
Step-by-step explanation:
First, order the data like so.
5, 7, 12, 12, 16, 17, 17
Then add them all up.
It is a sum of 86.
Finally divide
86/7=12.2
Since 12.2 movies aren't possible, let's say the mean is 12

What's the area of this
Answer:
133
Step-by-step explanation:
Because the figure is an irregular figure we need to break it up into two regular figures
The figure would be broken into..
A square with a side length of 4
And a rectangle with a length 13 and a width of 9
We now find the areas of the regular figures and add them together to get our answer
For the square.
To find the area of a square simply square the side length
Area = 4^2 = 16
For the rectangle
to find the area of the rectangle simply multiply the Length by the width
Area = 13*9= 117
Finally add the two areas together to get the area of the composite figure
117 + 16 = 133
Lucky Lanes Bowling Alley is putting this design on its roof.
Enter the volume of this design in cubic feet.
=====================================================
Explanation:
The block on top has length, width and height of 4, 4 and 20-4 = 16.
The volume of this block is 4*4*16 = 256 cubic feet.
The volume of the block down below is 160 cubic feet because 10*4*4 = 160.
The total volume is therefore: 256+160 = 416 cubic feet

Answer:
5725.65cm
Step-by-step explanation:
Because there are 10mm in every 1cm, we start by taking the 57256.5mm and divide that by 10, effectively moving the decimal point to the left by one number, resulting in 5725.65cm.

Sahil got 28 questions right on the math test. Angelina got 7 more wrong answers than Sahil. There were 40 questions on the test. How many answers did Angelina get right on the math test? Which equation represents this situation?
A. a + 7 = 12
B. a + 7 = 28
C. 7 + 12 = a
D. 7 = 40 - a
Answer:
40-28=12 Sahil got 28 right and 12 wrong
12+7=19 Angelina got 19 wrong and 21 right
40-19= 21
B would be correct
a +7=28

A group of friends went to lunch. The bill, before sales tax and tip, was $37.50. A sales
tax of 8% was added. The group then tipped 18% on the amount after the sales tax
was added. What was the amount, in dollars, of the sales tax?
Show your work.
Answer
question continued: what was the total amount the group paid, including tax and tip?
Answer:
Sales tax=3.00, total paid=47.79
Step-by-step explanation:
37.50 x .08=3.00 sales tax
37.50+3.00=40.50 amount with sales tax added
40.50 x .18=7.29 amount of tip
40.50 + 7.29=47.79 total with tip and sales tax

The solutions to the quadratic equation [tex]\rm x^2 + 2x = 25[/tex] is [tex]-1\pm \sqrt{26 }[/tex].
What is quadratic equation?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations.
The given equation is;
[tex]\rm x^2 + 2x = 25\\\\x^2+2x-25=0[/tex]
The solutions to the quadratic equation is determined by the following formula;
[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Where the value of a = 1, b = 2, and c = -25.
Substitute all the values in the formula;
[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\\rm x =\dfrac{-2\pm \sqrt{2^2-4\times 1\times (-25)} }{2\times 1}\\\\ x =\dfrac{-2\pm \sqrt{4+100} }{2}\\\\x =\dfrac{-2\pm \sqrt{104} }{2}\\\\x =\dfrac{-2\pm \sqrt{26 \times 2\times 2} }{2}\\\\x =\dfrac{-2\pm 2\sqrt{26 }}{2}\\\\x = 2 \times \dfrac{-1\pm \sqrt{26 }}{2}\\\\x=-1\pm \sqrt{26 }[/tex]
Hence, the solutions to the quadratic equation [tex]\rm x^2 + 2x = 25[/tex] is [tex]-1\pm \sqrt{26 }[/tex].

Find the cosine of ∠G (Must give explanation)
also why does my calculator say its undefined if I do the cos invert of (85/77) ??
cos^-1(85/77) = undefined ?? why
Answer:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
Step-by-step explanation:
Recall that cosine is the ratio of the adjacent side to the hypotenuse:
[tex]\displaystyle \cos(G)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]
The hypotenuse is always the side opposite to the right angle. In this case, it is
85.
The adjacent side to G is 36.
Therefore:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
For your other question, remember that in a right triangle, cosine is the ratio of the adjacent side to the hypotenuse.
As you know, the hypotenuse is always the longest side in a right triangle.
Therefore, the ratio of the adjacent side to the hypotenuse will never be greater than 1.
Since 85/77 is greater than 1, it is undefined.
The same applies to sine as well.
