So basically you would cut the block in half however you'd like but this is how I did it- first you would multiply one side the side I chose has the numbers 7*15*10 so you multiply those getting 1050 then set that aside and do the other side with the numbers of 6*5*10 which if you multiply you would get 300 then you add the first number 1050+300 = 1350 •tbh this might not be correct I tried•

2 points Bob flips a coin. He also spins the pointer on the spinner shown below. What is the probability that Bob flips the coin so that it lands tails up and spins the pointer so it stops on the letter R? * N E Your answer
Answers
Answer: 1/16 = 0.0625
Step by step solution:
The probability (P) of an event happening is
[tex]P=\frac{Numbe\text{r of ways it can happen}}{Total\text{ number of outcomes}}[/tex]When Bob flips the coin he has two options, head or tail. The probability that it lands tails up is:
[tex]P=\frac{1}{2}[/tex]The probability that the pointer stops on the letter R is:
[tex]P=\frac{1}{8}[/tex]Now, the probability of both events happening (tails up and pointer on R) is:
[tex]P=\frac{1}{2}\times\frac{1}{8}=\frac{1}{16}=0.0625[/tex]change this standard form equation into slope intercept form 6x - 2y=-8

3 miles/hour. At what rate is he approaching the top of the pole
when he is 100 feet away from the pole?
Answers
Answer:
375!
Step-by-step explanation:
3 x 100 = 300
Now he is at the pole. Now he has to get to the top of it
which your basically doing
3 x 100 = 300 + 75 = 375
( 375 - 75 = 300 300 ÷ 100 = 3 )

What is improper fraction and mixed fraction?
A mixed fraction is one that has both a correct fraction and a whole number portion, and whose value is consistently greater than 1. When the numerator is always higher than or equal to the denominator, the fraction is said to be inappropriate. 4/3, 7/3, 11/5, and other incorrect fractions are a few instances.
Here the road trip is 2457 miles long .
They already drive 128 [tex]\frac{53}{100}[/tex] miles.
That is in mixed fraction , we need to convert them in improper fraction , then,

SOLUTION
We want to select all triangles from the image that can be proven by the side angle side theorem which states that
If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
Now looking at the triangles
We can see that triangles in number 1, 2, 3 follows this theorem.
4 does not because the equal angles are not present
5, the triangles are congruent, but do not follow the SAS theorem
6 follows as we can see the equal sides and angle
7 shows two equal angles only, but we need one equal angles and two equal sides.
Hence the answer is 1, 2, 3 and 6 only

With respect to the given angle 30 degrees, we have the hypotenuse and want to find the opposite side.
The trig ratio relating opposite side and hypotenuse is SINE.
Thus, we can write:

If 45% don't want uniforms, it means that 45 out of 100 students don't want them, so the probability is 45/100 = 9/20

At a sale this week,a suit is being sold for $364. This is a 35% discount from the original price. What is the original price?
Answers
Okay, here we have this:
Considering the provided information, we are going to calculate the requested original price, so we obtain the following:
So we have the following formula:
Discount Price=Original Price*(100%-Discount)
Clearing for "Original price":
Discount Price=Original Price*(100%-Discount)
Original Price=Discount Price/(100%-Discount)
Replacing with the given data:
Original Price=Discount Price/(100%-Discount)
Original Price=$364/(100%-35%)
Original Price=$364/(65%)
Original Price=$364/(0.65)
Original Price=$560
Finally we obtain that the original price is $560.

Answers
It cost $159 to drive the van for 120 miles
Explanation:
The flat fee of the van = $99
The charge per mile = $0.50
Let m represent the number of miles
T = total cost
The total cost becomes:
T = 0.5m + 99
When you drive 120 miles, m = 120 miles
T = 0.5(120) + 99
T = 60 + 99
T = $159
Hence, it cost $159 to drive the van for 120 miles
Hello, I need help completing and showing appropriate steps for this problem. Thank you so much!
Answers
The first step is to factorise the quadratic expression on the right side of the equation. The expression is
x^2 + 9x + 20
We would find two terms such that their sum or difference is 9x and their product is 20x^2. The terms are 5x and 4x. Replacing 9x with 5x and 4x, it becomes
x^2 + 5x + 4x + 20
By factorising, it becomes
x(x + 5) + 4(x + 5)
Since x + 5 is common, it becomes
(x + 4)(x + 5)
Thus, the original expression becomes
x/(x + 4) + 3/(x + 5) = (x + 2)/(x + 4)(x + 5)
The lowest common multiple of the denominators on both sides of the equations is (x + 4)(x + 5). We would multiply each term in the equation by
(x + 4)(x + 5). It becomes
(x + 4)(x + 5)x/(x + 4) + 3(x + 4)(x + 5)/(x + 5) = (x + 2)(x + 4)(x + 5)/(x + 4)(x + 5)
By cancelling out common terms in the numerator and denominator, we have
x(x + 5) + 3(x + 4) = x + 2
We would expand the parentheses on both sides by multiplying the terms inside with the term outside. It becomes
x^2 + 5x + 3x + 12 = x + 2
By collecting like terms, we have
x^2 + 5x + 3x - x + 12 - 2 = 0
x^2 + 7x + 12 = 0
Again, We would find two terms such that their sum or difference is 7x and their product is 12x^2. The terms are 4x and 3x. Replacing 7x with 4x and 3x, it becomes
x^2 + 4x + 3x + 12 = 0
By factorising, it becomes
x(x + 4) + 3(x + 4) = 0
Since x + 4 is common, it becomes
(x + 3)(x + 4) = 0
x + 3 = 0 or x + 4 = 0
x = - 3 or x = - 4
The solutions are x = - 3 or x = - 4

There is more likelihood that it will rain tomorrow that today.
This means that the probabilty that it will rain tomorro is greater than the probability that it will rain today.
Therefore, the probability of rain tomorrow is more than 0.6
