Answer:
Area of triangle B is 112 cm²
Option A is correct option.
Step-by-step explanation:
The dimensions of triangle B are twice the dimensions of triangle A.
Area of triangle A = 28 cm²
We need to find area of triangle B
We know that if base = b and height = h for triangle A
The area of triangle A will be: [tex]Area_A=\frac{1}{2}\times b \times h[/tex]
The dimensions for triangle B will be:
[tex]h_B = 2 h_A\\b_B = 2 b_A[/tex]
Putting in formula we get:
[tex]Area_B=\frac{1}{2}\times b\times h \\Area_B=\frac{1}{2}\times (2b)\times 2(h)\\Area_B=4( \frac{1}{2}\times b\times h)\\Area_B=4(Area_A)[/tex]
SO, we get [tex]Area_B=4(Area_A)\\[/tex]
We have Area_A = 28 cm²
Area of triangle B Area _B is:
[tex]Area_B=4(28)\\Area_B=112\:cm^2[/tex]
So, Area of triangle B is 112 cm²
Option A is correct option.

kiran has used 4/5 of the pieces in his jigsaw puzzle. He has used 120 pieces. How many pieces are in the whole puzzle
Answer:
150
Explanation:
Since 120/4 = 30 we just need to add another 30 to find the answer.
120/4 = 30 (which is the same as 4/5 in the question.)
120 + 30 = 150.
There are 150 pieces total.
I'm hoping this is correct. Good luck with your studies!
After solving the equation, the number of pieces in the whole puzzle will be equal to 150 pieces.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the information in the question,
Let the total number of pieces in the jigsaw puzzle be x.
Pieces used by Kiran = 4/5 of the total pieces
Then, the equation as per the statement will be,
4/5 of x = 120
x = (120 × 5)/4
x = 30 × 5
x = 150 pieces.

The reciprocal of 7 is 1/7.
What is a reciprocal?The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.
Given:
The number is 7.
Let n be the reciprocal of 7.
If n is a real number, then 1/n will be n's reciprocal.
To find the reciprocal of 7:
We need the value that can give us 1 when multiplied by 7.
That means,
n x 7 = 1
Divide by 7 to both sides,
n = 1/7
Therefore, the reciprocal is 1/7.

Bonnie is saving money to buy a used car. She can afford a payment of $250 a month for a
year.
She has 1,750 in her savings account for a down payment.
Answer:
y = -250 + 1,750
Step-by-step explanation:
Bonnie is paying $250 every month, so it is deducting, which is subtraction.
She already had $1,750 in her account, so that is the y-intercept.

NOT is coded as LKF and FLY is coded as TNA, then which of the following word/s has/have correct coding? (1) TOP – FKJ (2) RUN – IFM (3) MUG – MES (4) HOT – RKG which one is correct answer
Answer:
(1) and (3) are correct optionsStep-by-step explanation:
NOT is coded as LKFFLY is coded as TNAUsing alphabet, we can see that:
NOT = 14, 15, 20 ⇔ 13+1, 13+2, 13+7 ⇒ LKF = 12,11,6 = 13-1, 13-2, 13-7
Coding for each letter is 13 + x ⇒ 13 - x
(1) TOP ⇒ FKJ
TOP = 20,15,16 ⇒ 13-7, 13-2, 13-3 = 6,11,10 = FKJ Correct(2) RUN ⇒ IFM
RUN = 18,21,14 ⇒ 13-5,13-8,13-1 = 8,5,12 = HEL ≠ IFMIncorrect(3) MUG ⇒ MES
MUG = 13,21,7 ⇒ 13+0, 13-8, 13+6 = 13,5,19 = MESCorrect(4) HOT ⇒ RKG
HOT = 8,15,20 ⇒ 13+5,13-2, 13-7 = 18,11,6 = RKF ≠ RKGIncorrect

Shannon run 1.5 km more on Friday than on Saturday.
Step-by-step explanation:
From the given table
Distance run on Friday = 4/2 = 2 kmDistance run on Saturday = 1/2 = 0.5 kmIn order to run how many more kilometers Shannon run on Friday than on Saturday, we need to subtract the distance run on Saturday from the distance run on Friday.i.e.
Friday run - Saturday run = 2 - 0.5
= 1.5 km
Thus, Shannon run 1.5 km more on Friday than on Saturday.

The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults. On a certain day, 1,130 enter 5)3 festival and 2, 520 is collected. Given , = number of child tickets and a= the number of adult tickets. How many children and how many adults attended?
Answer:
Number of child tickets = 800
Number of adult tickets = 330
Step-by-step explanation:
Let c = number of child tickets
and a= the number of adult tickets.
We are given:
The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults.
On a certain day, 1,130 enter the festival and 2, 520 is collected.
Making equations:
[tex]c+a=1130[/tex] (because total people entered are 1130, so adding number of adult and child tickets will give us total number of people)
[tex]1.50c+4.00a=2520[/tex] (because total money collected is 2520, so adding coat of adult and child tickets will give us total money)
Now, solving these equations simultaneously, we can find values of x and y
Let:
[tex]c+a=1130--eq(1)\\1.50c+4.00a=2520--eq(2)[/tex]
From equation 1 find value of c and put it in eq(2)
[tex]c+a=1130\\c=1130-a[/tex]
Putting value of c in eq(2)
[tex]1.50c+4.00a=2520\\Put\:c=1130-a\\1.5(1130-a)+4a=2520\\1695-1.5a+4a=2520\\-1.5a+4a=2520-1695\\2.5a=825\\a=\frac{825}{2.5}\\a=330[/tex]
So, we get value of a = 330
Now, punting value of a in eq(1) to get value of c
[tex]c+a=1130\\c+330=1130\\c=1130-330\\c=800[/tex]
So, we get value of c = 800
Therefore:
Number of child tickets = c= 800
Number of adult tickets = a = 330
