Answers
Answer:
x = 2
y = 6
Step-by-step explanation:
x + y = 8
x + (3x) = 8
4x = 8
4x ÷ 4 = 8 ÷ 4
x = 2
-------------------------------
y = 3x
y = 3(2)
y = 6
----------------------------------
x + y = 8
(2) + (6) = 8
8 = 8

Which postulate proves these two
triangles are congruent?
A. ASA
B. SAS
C. None, not congruent
D. HL
Answers
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.

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?!
Answers
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

Answer:
$347.08
Step-by-step explanation:
10' x 12'6" = 125 ft^2

find the length of the third side of the right triangle!!!!
Answers
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) =
Answers
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

Jomaya has $15. She saves $2 every day. How many days will it take Jomaya to save $25?
Answers
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

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
Answers
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.

A rhombus has 10-in.Sides, two of which meet to form the indicated angle. Find the area of the rhombus.(Hint: Use a special right triangle to find height.) The angle is 30 degrees.
Answers
Answer:
50 in²
Step-by-step explanation:
Given that the side of the rhombus is 10 in, and it has an angle of 30°
The formula for the angle in a rhombus is given as
Sin Φ = height / side
Sin 30 = height / 10
height = 10 * sin 30
height = 10 * 0.5
height = 5 inches
One of the formulas for calculating the area of a rhombus is given as
Area = height * side, and thus, we have
Area = 5 * 10
Area = 50 square inches.
Therefore, the area of the rhombus is calculated to be 50 in²
