Answers

Answer:

20cm squared

Step-by-step explanation:

so the scale factor is 1:2 so you just double the area so,

10cm squared x 2 = 20cm squared

Answer:

D: 40

Step-by-step explanation:

If the scale factor is 1:2 it means that each side is twice as big after being scaled. However, because the area is width * height that means that the area of the scaled one gets doubled two times, so is actually 4x bigger. This means the answer is 4 * 10 = 40 square cm

Answers

Answer: 9/8

Step-by-step explanation:

The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.

The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?

What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.

Answers

Answer:

i mean might as well get free points now that its 2 weeks old

Step-by-step explanation:

Answer:

Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.

Width = A

Length = B

Diagonal = C

so: a2+b2=c

2502+1002=c2

2500+10000=c2

12500=c2

c=√12500

c=111.80 yards

Find all possible solutions for x and y such that △ABC is congruent to △DEF.

△ABC: sides of length 19, 25, and 3x − 3.
△DEF: sides of length 25, 15, and 5 − y.

△ABC ≅ △DEF when x is ___ and y is ___.

Answers

Answer:

Step-by-step explanation:

it means the ABC And DEF have side lengths of 15,19, 25

so 3x-3 = 15

x = 6

5-y = 19

GUYS PLEASE HELP I MARK BRAINLIEST 5 STARS IM SORRY ABOUT THE POINTS I ONLY HAVE 13 Andre’s school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.

Write an equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers, b.
t=b-4

The school office receives a bill for the supplies in the amount of $348. Write an equation with t and b that describes this situation.
b+t=348

Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write an equation that shows this substitution.
b+(b-4)=348

b=176

How much did the school pay for a set of beakers? $____

How much did the school pay for a pack of test tubes? $____

Answers

Answer:

this is not originally by me

Step-by-step explanation:

10t = b - 4

12b+8t = $348

This is a system of equations. I’ll be solving through substitution.

In the first equation. solving for b (the easier variable to isolate) gives you:

b = 10t + 4

Substitute this into the second equation:

12(10t+4) +8t = 348

120t+48+8t = 348

128t = 300

t = 2.34375 —> round it to the nearest cent to get 2.34 dollars

b = 10t+4

b = 10(2.34)+4

b = 27.4 dollars

Zachary places daisies and magnolias in a vase. If daisies cost x dollars, magnolias cost y dollars and a vase costs v dollars, mark all equations which represent the cost of 20 vases of 40 daisies and 80 magnolias.

Answers

Answer:

[tex]Total = 20v + 40x + 80y[/tex]

[tex]Total = 20(v + 2x + 4y)[/tex]

Step-by-step explanation:

The options were not given,en but the question can still be solved.

Given

[tex]Daises = \$ x[/tex]

[tex]Magnolias = \$ y[/tex]

[tex]Vase = \$ v[/tex]

Required

Determine the cost of 20 vases, 40 daises and 80 magnolias

If 1 vase costs $v, then

[tex]20\ vases = 20 * v[/tex]

[tex]20\ vases = 20v[/tex]

If 1 daises costs $x, then

[tex]40\ daises = 40 * x[/tex]

[tex]40\ daises = 40x[/tex]

If 1 magnolias costs $y, then

[tex]80\ magnolias = 80 * y[/tex]

[tex]80\ magnolias = 80y[/tex]

[tex]Total = 20v + 40x + 80y[/tex]

Another expression that represents the total is to factorize the expression.

[tex]Total = 20(v + 2x + 4y)[/tex]
