If the height of a parallelogram is 4 times more than it’s base, and the area is 221 sq in, what is the base and height?
Answer:
Base = 13in
Height = 17in
Step-by-step explanation:
Step-by-step explanation:
height of a parallelogram = 4 times more than it’s base
Let height = H
Base = B
H = 4 + B
area of the parallelogram = 221 in²
area of the parallelogram = base × height
221 = B × H = B × (4+B)
221 = 4B + B²
B² + 4B - 221 = 0
Using almighty formula to find B
See attachment for explanation
From the calculation:
Since the dimension of the parallelogram can't be negative, B = 13in
Height = B + 4 = 13+4
Height = 17in
Answer:
Base = 13 inches
Height = 17 inches
Step-by-step explanation:
The formula to find the area of a parallelogram = Base × Height
Let's represent Base = B
Height = H
From the question, the height is 4 times more than the Base
Height(H) = B + 4
Area = 221 square inches
Therefore, area of a parallelogram = Base × Height
221 sq in = B ×( B+4)
221 sq in = B² + 4B
B² + 4B - 221 = 0
We would solve the quadratic equation using factorisation method. Hence,
B² + 17B - 13B - 221 = 0
(B²+ 17B) - (13B - 221) = 0
B(B + 17) - 13(B + 17) = 0
(B + 17) (B - 13) = 0
B + 17 = 0
B = - 17
Or
B - 13 = 0
B = 13.
From the above calculation, since B = Base
B = -17 inches Or 13 inches
The base of a parallelogram cannot be negative, hence , The Base of the Parallelogram = 13 inches.
We are told that the height of the Parallelogram is 4 times more than the Base. This was represented but the equation
B + 4 = H
Since B = 13 :
13 + 4 = H
Height(H) = 17 inches.
Therefore, The base of the Parallelogram is 13 inches while the height of the Parallelogram is 17 inches.
In an experiment, the probability that event A occurs is 5/8 , the probability that event B occurs is 2/9 , and the probability that events A and B both occur is 1/5 . What is the probability that A occurs given that B occurs?
Step-by-step explanation:
p(A|B) = p(A and B) / p(B) =(1/5) / (2/9) = 0.9
The probability that event A occurs is 5/8 , the probability that event B occurs is 2/9 , and the probability that events A and B both occur is 1/5 . The probability that A occurs given that B occurs is 0.9.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
The probability that event A occurs is 5/8
The probability that event B occurs is 2/9
The probability that events A and B both occur is 1/5.
So, The probability that A occurs given that B occurs
P(A|B) = P(A and B) / P(B)
= (1/5) / (2/9)
= 0.9

An animal shelter houses dogs, cats, and rabbits. There are 126 animals at the shelter. Of the animals, 13 are cats. Three fourths of the remaining animals are dogs. How many of the animals are rabbits? Show your work.
Answer:
28 rabbits
Step-by-step explanation:
From the statement, you can write the following:
d+c+r= 126
d=dogs
c= cats
r= rabits
Then, you have that there are 13 cats and that three fourths of the remaining animals are dogs:
c=13
d=(126-13)*(3/4)= 113*(3/4)= 85
Now, you can isolate r, to find the number of rabbits:
r=126-d-c
r= 126-85-13
r= 28
According to this, the are 28 rabbits.

Small scooters cost £80 and large scooters cost £130. A school buys few scooters for the playground for £1000. How many of the smaller and larger scooter did they buy?
Answer:
Small scooters = 6
Large scooters = 4
Step-by-step explanation:
Let S represents small scooter and L represents large scooter
The cost of a small scooter is £80
Mathematically, the cost of S number of small scooters is
80S
The cost of a large scooter is £130
Mathematically, the cost of L number of large scooters is
130L
The total amount spent on both scooters is £1000
Mathematically,
80S + 130L = 1000
So we have 2 unknowns and only 1 equation. Therefore, we have use trial and error method .
Trial and Error Method:
80S + 130L = 1000
80S = 1000 - 130L
S = (1000 - 130L)/80
Let’s suppose they bought 1 large scooter
S = (1000 - 130(1))/80
S = 10.875
Number of scooters cannot be in fraction so 1 doesn’t work
Let’s suppose they bought 2 large scooter s
S = (1000 - 130(2))/80
S = 9.25
Number of scooters cannot be in fraction so 2 doesn’t work
Let’s suppose they bought 3 large scooter s
S = (1000 - 130(3))/80
S = 7.625
Number of scooters cannot be in fraction so 3 doesn’t work
Let’s suppose they bought 4 large scooters
S = (1000 - 130(4))/80
S = 6
So that means they bought 6 small scooters and 4 large scooters.
Similarly, other combinations for scooters don’t work since they yield either fractional value or negative value which cannot be correct.
Therefore, the only possible combination of small and large scooters is
6 Small scooters
4 Large scooters
Verification:
80S + 130L = 1000
80(6) + 130(4) = 1000
480 + 520 = 1000
1000 = 1000 (satisfied)

Answer: The answer is 580
Step-by-step explanation: you first do the front side which is 20 x 10 which is 200. You multiply 200 by 2 since the front and back are the same.
then you move on to the sides.
the bottom of the side is 3. The height is 20. 3 x 20 is 60. Since there are 2 sides, you will do 60 x 2 which is 120.
now we move on too the top. The width of width is 3. and the length is 10. 10 x 3 is 30. Since the bottom is also the same, you do 30 x 2. You add all the numbers.
So 400 (from the front and back) + 120 (from the sides) + 60 ( from the top and bottom)
thiss all equals 580. sorry if it is a bit confusing I just understood it too. I am 14 trying to get math a year above me.

This year (10 years after you first took out the loan), you check your loan balance. Only part of your payments have been going to pay down the loan; the rest has been going towards interest. You see that you still have $112,681 left to pay on your loan. Your house is now valued at $190,000. Your current situation How much of the original loan have you paid off? (i.E, how much have you reduced the loan balance by? Keep in mind that interest is charged each month - it's not part of the loan balance.)
Answer:
The below is the first of paragraph in the question which is missing:
Suppose that 10 years ago you bought a home for $150,000, paying 10% as a down payment, and financing the rest at 8% interest for 30 years.
$22,319.00
Step-by-step explanation:
In order to determine the portion of the original loan that has been paid off,we need to ascertain the original loan amount as below:
loan amount=purchase price of the home-down payment
purchase price is $150,000
down-payment =10%*$150,000=$15,000
loan amount=$150,000-$15,000=$135,000
If the loan amount has reduced to $112,681,hence the loan amount paid off is the difference between the original loan amount and the balance now:
original loan paid off=$135,000-$112,681=$22,319.00

Answer:
A & C
Step-by-step explanation:
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles
Answer:
Triangles A and C are congruent.
Step-by-step explanation:
Congruent triangles are when two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The total of the angles of all triangles is 180, so then add all the angles then subtract that number from 180.
A: 110+30=140 (180-140=40)
B: 30+45=75 (180-75=105)
C: 110+40=150 (180-150-30)
Since Triangles A and C have the same angles, then they are congruent!!!

The price of a washing machine was decreased by 20% to £640.
What was the price before the decrease?
Answer:
£800
Step-by-step explanation:
For this question we need to utilise decimal multiplier. Since this is a decrease question to work out the decimal multiplier you have take 100 away from the percentage and then divide by 100. If this was an increase question then we would had to add 100 to the percentage and then divide by 100. Since the question is asking for the price before the decrease we are going to have to divide the multiplier by the price so,
⇒ Work out the multiplier by taking 100 away from the percentage and then dividing by 100
→ 100 - 20 = 80 ↔ 80 ÷ 100 = 0.8
⇒ The multiplier is 0.8, now we have to divide the multiplier by the price
→ 640 ÷ 0.8 = 800
The price of a washing machine was decreased by 20% to £640. The price before the decrease was £800
"Heavy Water" is a name given to a compound used in some nuclear reactors. Heavy water costs about $1,500 per gallon. If a nuclear plant spent $10,500 on heavy water, how many gallons of water were bought?
Answer:

find the values of t6 and d for the arithmetic sequence with t6= 4 and t10= -4
Answer:
t1 = 14 d= -2
Step-by-step explanation:
tn = t1 + d ( n-1)
t6 = t1 + d(6-1)
4 = t1+ 5d
t10 = t1 +d (10-1)
-4 = t1 +d9
Take the two equations and subtract to eliminate a1
4 = t1+ 5d
- (-4 = t1 +d9)
-------------------------
4 = t1+ 5d
+4 =- t1 -d9
-------------------------
8 = -4d
Divide each side by -4
8/-4 = -4d/-4
-2 =d
Now we can find t1
4 = t1+ 5d
4 = t1 + 5(-2)
4 = t1 -10
Add 10 to each side
4+10 = t1
14 = t1
Answer:
A
Step-by-step explanation:
t1 = a
tn = a + (n-1)d
t6 = a + 5d = 4
a = 4 - 5d
t10 = a + 9d = -4
4 - 5d + 9d = -4
-8 = 4d
d = -2
a = 4 - 5(-2)
= 4 + 10
= 14

PLZ MARK BRAINLIEST!!!
If m ∠ABC=85° and m ∠DBC=61° then m angle ABD=24°. Hence the option A is correct.
What is an angle?
An angle is the figure formed by two sides of a figure , sharing a common endpoint, called the vertex of the angle.
How to determine angle between lines?From the given figure we can conclude that ∠ABD=∠ABC-∠DBC.
We have been given that m ∠ABC=85° and m ∠DBC=61°
∠ABC=85/m and ∠DBC=61/m
Put in the above equation
∠ABD=∠ABC-∠DBC
∠ABD=85/m-61/m
=24/m
we have been find m ∠ABD so we have to multiply 24/m by m is 24°.
Hence the value of m angle ABD=24 degrees.
