A squared + B squared = C squared
( 7 x 7 ) + ( 3 x 3 ) = c x c
58 = c squared
C = 7.6 miles away

Using isosceles triangle theorems solve for x and y
klio [65]
Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50

Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115

As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5

A contractor is building a pool labeled ABCD on the plans. If AC = 5y + 6 and BD = 8y-3, what value of y ensures the pool is a r
KIM [24]

The value of y that ensures the pool is a rectangle is 3. Option D

<h3>How to determine the value</h3>

The formula for perimeter of a rectangle is expressed as;

Perimeter = 2 ( length + width)

It is important to note that parallel sides of a rectangle are congruent, that is, they are equal.

Given the sides as;

  • AC = 5y + 6
  • BD = 8y-3

5y + 6 = 8y -3

collect like terms

5y - 8y = -3 - 6

-3y = -9

Make 'y' the subject

y = 3

Thus, the value of y that ensures the pool is a rectangle is 3. Option D

A bakery makes 40 different flavors of muffins. 25% of the flavors have chocolate as one of the ingredients. Draw a tape to show
kobusy [5.1K]

Answer:

10

Step-by-step explanation:

A bakery makes 40 different flavors of muffins.

25% of the flavors have chocolate as one of the ingredients.

Convert 25% to fraction:

25\%=\dfrac{25}{100}=\dfrac{1}{4}

So, there are

40\cdot \dfrac{1}{4}=10

muffins which have chocolate as one of the ingredients.

In attached tape diagram:

green - with chocolate

blue - without chocolate

PLEASE HELP, TY! WILL MARK BRAINLIEST!
just olya [345]

Answer:  y = 6

Step-by-step explanation:

The opposite sites of a parallelogram should be equal length. Therefore 7y = y + 36, so 6y = 36 and thus y = \boxed{6}.
