Answer:
1 set of A= $0.15
1 set of B= $0.20
Total Stamps bought = 37
Total purchase = 37
Let X= Set A of $0.15 each
Y= Set B of $0.20 each
x+y = 37----------X=37-Y
0.15X + 0.20Y = 6.60
0.15(37-Y) + 0.20Y = 6.60
5.55- 0.15Y + 0.20Y =6.60
0.05 Y = 6.60-5. 55
Y=1.05/ 0.05= 21
X= 37-21= 16
can someone plz plz plz help me?????
a) x+1+x+1+x+1+x+1=56 x=6.5
b) 2(6.5)+1=14cm
The ratio of seventh graders to sixth graders on a chess team is 5 to 3 . What is the ratio of seventh graders to total chess players ? Enter the correct answer in the box
Answer: 5 : 8
Step-by-step explanation:
The ratio of seventh graders to sixth grader on the team is 5 : 3.
Assuming that only seventh and sixth graders are in the team, the total number of chess players at the most simple basis is:
= Number of seventh grade students in ratio + Number of sixth grade students in ratio
= 5 + 3
= 8 students
There are 5 seventh graders so the ratio will be:
= 5 : 8
Note: The chess team will most likely have more than 8 members but the ratio of seventh graders to total chess players will still be 5 : 8.

What’s the length of a segment whose endpoints are (8,-6) and (-4,2)?
Answer:
Step-by-step explanation:
Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8. Use the Pythagorean Theorem to find the length of the hypotenuse:
length of hypotenuse = +√(8² + 12²) = √208 = 4√13 (Answer A)

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′. Which rule describes this transformation? F.(x, y) → (x — 5, y — 3) G.(x, y) → (x + 5, y + 3) H.(x, y) → (x — 3, y — 5) J.(x, y) → (x + 3, y + 5)
Answer:
G.(x, y) → (x+5, y+3)
Step-by-step explanation:
The rule would be (x+5, y+3) and the only one with that rule is G.
A triangle has three angles that measure 30 degrees, 70 degrees What is the value of x?
Answer:
x = 80
Step-by-step explanation:
Sum of all the angles of triangle = 180
30 + 70 + x = 180
100 + x = 180 {Subtract 100 from both sides}
x = 180 - 100
x = 80°

What is the measure of angle z in this picture?
Answer:
z = 137 degrees
Step-by-step explanation:
Angle 43 and angle z make a straight line, which is 180 degrees
43+z = 180
Subtract 43 from each side
43+z-43 = 180-43
z =137

David leaves the supermarket at 1810
He drives 20 miles to his home.
The speed limit for the journey is 30 mph.
David drives within the speed limit.
(b) Can David get home before 1900?
Give reasons for your answer.
Answer:
The total distance David has to travel 20 miles.
The speed limit is 30 mph. He leaves supermarket at 18 10 , he has 50 minutes to get home before 1900.
when traveling within the speed limit he can reach on time because he has to travel only 20 miles which is possible and it won't take him 1 hour according to the 30 mph speed limit.
GHJU is a rhombus. how could you prove that <3~=<2? this doesn’t have to be a formal proof, just a basic outline of an augment. how would you approach this proof?
Answer:
Angle 3 is equal to Angle 2 because when you have a rhombus, the diagonals will always bisect the angles.

Consider the cases SSS, AAS, ASA, SAS, and SSA. For which of these cases are you unable to solve the triangle using only the Law of Sines?
Answer:
SSS and SASStep-by-step explanation:
To use the law of sines we need to know two angles and one side or two sides and one angle which should be opposite to one of known sides.
SSS - unable to solve as no angle is knownAAS - two angles and non-included side, able to find the missing angle solve the restASA - two angles and the included side, able to find the missing angle solve the restSAS- two sides and the included angle, unable to solveSSA - two sides and non-included angle, able to find the other angles and solve fullyWhat is an equation of the line that passes through the points (-1, 6) and

Erik took out a loan for $8400 for 6 years at a compound interest rate of 5.5%-
How much interest does Erik owe from the loan?
$11,582.28
$108,084.86
$2,772
$3,182.28
Answer:
$2772
Step-by-step explanation:
Given data
Principal= $8400
Rate= 5.5%
Time= 6 years
The expression for the simple interest on the loan is found using the expression below
SI= PRT/100
substitute
SI= 8400*5.5*6/100
SI= 277200/100
SI= $2772
Hence the simple interest is $2772
Answer:The answer is actually 3,182.28
Step-by-step explanation:
Find the volume of the figure. Round to the nearest tenth if necessary.
1 point
3.4 in
4.8 in
25
Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3

Twenty years ago, Mr. Davis purchased his home for $160,000. Since then, the value of
the home has increased about 5% per year. How much is the home worth today?
Answer:
The home is worth $424,528 today
Step-by-step explanation:
To get the worth of the home today, we are going to use the exponential formula
We have this as follows;
A = P(1 + r)^t
where A is the value of the house after some time t
P is the initial value the home was worth which is $160,000
r is the rate of increase in the price of the home which is 5% = 5/100 = 0.05
t is the number of years which is 20
substituting these values;
A = 160,000(1 + 0.05)^20
A = $424,528
What is the probability of landing on red and rolling a number greater than 2?
