Ab is 15
Bd is 8
CD is 15
Step-by-step explanation:
If you dilate a image by a factor of 2 you are multiplying each side by 2.
Side AC = Original AC x 2 = 8 x 2 = 16
Side AB = Original AB x 2 = 15 x 2 = 30
Side BD = Original BD x 2 = 8 x 2 = 16
Side CD = Original CD x 2 = 15 x 2 = 30

Step-by-step explanation:
x= 180 - 121 = 59º
59 + 40 + z = 180
99 + z = 180
z= 81º
y = 40º
x = 180 - (81 + 40)
x = 59

Solve the problem by multiplying first.
Jamian bought a total of 35 bagels and donuts for a morning meeting. He paid a total of
$25.75. Each donut cost $0.55 and each bagel cost $1.20. The system of equations
b + d = 35
1.200 + 0.55d = 25.75 models this situation, where b is the number of bagels and d
is the number of donuts. How many of each did Jamian buy?
{ 1.200
Jamian bought
bagels and
donuts.
Answers
Answer:
Number of bagels = 10
Number of donuts = 25
Step-by-step explanation:
Let Number of bagels = b
Number of donuts = d
As given,
Each donut cost $0.55 and each bagel cost $1.20
⇒ Cost of d donuts = $0.55d
Cost of b bagels = $1.20b
Also given,
Jamian bought a total of 35 bagels and donuts
⇒ b + d = 35 ........(1)
Also,
He paid a total of $25.75.
⇒ 1.20b + 0.55d = 25.75 .........(2)
Now,
Multiply equation (1) by 1.20 , we get
1.20( b + d = 35 )
⇒1.20b + 1.20d = 42 ..........(3)
Now,
Subtract equation (2) from equation (3), we get
1.20b + 1.20d - ( 1.20b + 0.55d ) = 42 - 25.75
⇒1.20b + 1.20d - 1.20b - 0.55d = 16.25
⇒0.65d = 16.25
⇒d = [tex]\frac{16.25}{0.65}[/tex] = 25
⇒d = 25
Put the value of d in equation (1) , we get
b + d = 35
⇒b + 25 = 35
⇒b = 35 - 25 = 10
⇒b = 10
∴ we get
Number of bagels = b = 10
Number of donuts = d = 25

given a triangle with a perimeter of 56in. we know the first side is 3 inches less than twice the length of the second side, and the third side is 10 inches more than half the length of the second side. if the second side length is h, how long is the longest side? write an equation to solve for the variable.
Answers
Answer:
Side A = 25 in
Side B = 14 in
Side C = 17 in
Step-by-step explanation:
Perimeter of a triangle = 56 in
Side B = x
Side A = 2x - 3
Side C = 1/2x + 10
Perimeter of a triangle = side A + Side B + side C
56 = (2x -3) + x + (1/2x + 10)
56 = 2x - 3 + x + 1/2x + 10
56 + 3 - 10 = 2x + x + 1/2x
49 = 3 1/2x
Note: 3 1/2x = 3.5x
49 = 3.5x
x = 49/3.5
x = 14 in
Side B = x = 14 in
Side A = 2x - 3
= 2(14) - 3
= 28 - 3
= 25 in
Side C = 1/2x + 10
= 1/2(14) + 10
= 7 + 10
= 17 in

Answers
y = 2x
If you line the table vertically, you can see the x value is +1 because how does 0 go to 1, you add one to it.
With the y variable, you can view its being multiplied by 2 since 5x2 = 10 , 10x2 = 20 and so on.
Therefore the function rule is y=2x
Benjamin bought a 3-pound bag of flour for $6.95. What is the unit price per ounce of flour? (1 pound = 16 ounces)
Answers
Answer:
Step-by-step explanation:
Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3
16 · 3 = 48
to find the price you divide the total price by number of oz.
6.95 ÷ 48 ≈ 0.1448
since money is measured in hundreths, you would round up (because thats how money works) so it would be roughly 15 cents. unless your teacher wants you to round down to 14 cents
Ranbir bought a rectangular field of area 24000 square metres and width 120 m. He wants to fence it with two rounds of wire. Find the length of wire that will be required to fence the field.
Answers
Answer:
640 metres
Step-by-step explanation:
Area of a rectangular field = 24000 square metres
Width of a rectangular field = 120 metre
Also,
Area of a rectangular field = Length × Breadth
24000 = Length × 120
Length = [tex]\frac{24000}{120}=200[/tex] metre
Length of wire required to fence the field = Perimeter of the rectangular field
= 2 (length + width)
= 2 (200 + 120)
= 2 (320)
= 640 metres

What is the fewest number of consecutive primes, starting with 2, that when summed produce a number divisible by 7?
Answers
Answer:
5
Step-by-step explanation:
The consecutive primes starting from 2 are
2, 3, 5, 7, 11
Summing gives 2 + 3 + 5 + 7 + 11 = 28
and 28 is divisible by 7
Thus the required number of primes is 5
The fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.
To determine what is the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7, the following calculation must be performed:
2 + 3 = 5 2 + 3 + 5 = 10 2 + 3 + 5 + 7 = 17 2 + 3 + 5 + 7 + 11 = 28 28/7 = 4
Therefore, the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.

Answers
Answer:
80
Step-by-step explanation:
So I here's my thought process on this:
200 divided by 2 is 100
100 - 40% is 60, leaving 40 behind.
So double that and it would be:
200 - 40% is 120
200 - 120 = 80
80% is the answer.
