The circle graph shows how Tremaine divided his time on the computer last week.
Tremaine used the computer a total of 30 hours last week. How many more hours did Tremaine use the computer to play games than to do research?
A. 1.5 hours
B. 20 hours
C. 6 hours
D. 7.5 hours
Answer:
A:1.5 hours
Step-by-step explanation:
all you have to do is figure out 5% of 30 which is 1.5
The required number of hours more, Tremaine uses the computer to play games than to do research is 6 hours.
What is the percentage?The percentage is the ratio of the composition of significant value to the overall composition of significance value multiplied by 100.
Here,
As mentioned in the question Tremaine used the computer for a total of 30 hours last week.
So from the circle graph:
Hour spend on games = 25% of 30
= 0.25 * 30
= 7.5 hours
Hours spend on research = 5% of 30
= 1.5 hours
Thus, the required number of hours more, Tremaine uses the computer to play games than to do research is 7.5 - 1.5 = 6 hours.

find the length of the third side of the right triangle!!!!
Answer:
8
Step-by-step explanation:
There are two ways to solve this!
1. Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
100 - 36 = b^2
64 = b^2
8 = b
2. Shortcut using 3-4-5 triangles
A 3-4-5 triangle has to do with the ratios of each side.
In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

The letters P-R-O-B-A-B-I-L-I-T-Y are written on a set of cards. You mix the cards thoroughly. Without looking, you draw one letter then you draw another without replacing the first. Find the probability that you will select a P followed by a Y.
P(P, then Y) =
Answer:
P(P, then Y)=(1/11)(1/10)=1/110
Step-by-step explanation:
The number of letters in probability is 11.
There is 1 P.
The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11. Thus:
Probability of drawing a P on the first draw is 1/11.
There are now 10 letters left. There is 1 Y. so
Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.
The probability of drawing a P on the first draw and a Y on the second draw is
(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)
P(P, then Y)=(1/11)(1/10)=1/110

Q.1 Write the algebraic expressions
(i) Three times p added to four times r
(ii) The difference of 2p and 3q when 2p is less than 3q
(iii) Two-thirds of x added to 2y [3]
help?!
Answer:
(i) 4r + 3p (ii) 3q - 2p when 3q > 2p (iii) 2y + 2/3 x [not sure what [3] means]
Step-by-step explanation:
So for part (i) 3 multiply p added to 4 times r = 3p + 4r
For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!
(iii) I'm not sure what the [3] means but just using the numbers [tex]\frac{2}{3}[/tex]x, since of means multiply and add 2y then you have 2y + [tex]\frac{2}{3}[/tex] x

Jomaya has $15. She saves $2 every day. How many days will it take Jomaya to save $25?
Answer: 12.5
Step-by-step explanation: 2times 12.5 is 25
Answer:
5 days
Step-by-step explanation:
To find out this question, we can subtract the amount she wants to get, 25, by the amount she has, 15:
25 - 15 = 10
So, Jomaya wants to save up $10, and because she saves $2 every day, we can divide:
10 / 2 = 5
So, it will take Jomaya 5 days to save $25

Step-by-step explanation:
m=3 and through (2, -1) in slope-intercept
Answer:
y = 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, then
y = 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = 3x - 7 ← equation of line

Which postulate proves these two
triangles are congruent?
A. ASA
B. SAS
C. None, not congruent
D. HL
Answer:
it may be B but I think it's C
Step-by-step explanation:
not sure if this is right, but I would say not congruent. it may be sas but in order for it to be sas then the Angle must be in-between the two congruent sides
Both triangles are congruent by (SAS) side-angle-side postulate.
The correct option is B.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical.
Given,
Two triangles
ABC and DEC
AB = DE (Given)
BC = EC (Given)
∠ACB = ∠DCE (Vertical angles at intersection of DB and AE)
By, Side-Angle-side theorem of congruent triangles,
ΔABC ≅ΔDEC
Hence, by side-angle-side (SAS) postulate, both triangles are congruent.

Abha is climbing a mountain. While covering 20 yards of horizontal distance, Abha’s elevation increases by 40 yards. Consider Abha’s climb as a linear function.
A drawing shows a girl hiking. The vertical distance is forty yards. The horizontal distance is twenty yards.
What is the slope of her climb?
Answer:
The answer is 2
Step-by-step explanation:
The slope of Abha's climb is given by the equation
Slope m = 2
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be A
Now , let the point be P ( x , y )
And , the equation is given by
The horizontal distance covered by Abha x = 20 yards
The vertical distance covered by Abha y = 40 yards
Now , the slope of the point is given by the equation
Slope m = vertical distance covered by Abha / horizontal distance covered by Abha
Substituting the values in the equation , we get
Slope m of Abha's climb = y/x
Slope m of Abha's climb = 40 / 20
Slope m of Abha's climb = 2
Therefore , the slope of the line is m = 2
Hence , The slope of Abha's climb is given by the equation Slope m = 2
