Answer:

The length of diagonal BD is 11·(1 + √3)

The length of diagonal AC = 22

Step-by-step explanation:

The given data are;

Quadrilateral ABCD = A kite

The length of segment AD = 22

The measure of ∠DAE = 60°

The measure of ∠BCEE = 45°

Whereby, triangle ΔADE = A right triangle, and DE is the perpendicular bisector of AC, by trigonometric ratio, we have;

AE = EC

DE = 22 × sin(60°) = 11·√3

AE = 22 × cos(60°) = 11

∴ AE = EC = 11

BE = EC × tan(∠BCE) = 11 × tan(45°) = 11

The length of the diagonal BD = BE + DE (By segment addition property)

∴ BD = 11 + 11·√3 = 11·(1 + √3)

The length of diagonal BD = 11·(1 + √3)

The length of diagonal AC = AE + EC

∴ AC + 11 + 11 = 22

The length of diagonal AC = 22.

Check out if I'm right Plz explain..if u have a different answer

Ronch [10]

Answer:

A C

Step-by-step explanation:

A is true.The numerator does have 3 terms. The constant term (the 3 at the end) is still a term and counts as a term.

A constant term does not count as a coefficient so b is not right, just as you have indicated by not underlining it.

C is true. In fact, 2 is the leading coefficent of the denominator.

Either A is true or D is, but I don't think they both are. You need a modifier to claim that D is true. If the statement said the numerator has at least 2 terms then both A and D would be true. Without the at least, you have to pick one and the one I choose is A

This is the tough one. Very sticky. You would think it is true, but it isn't. A constant term is not a coefficient. Coefficients only count when they are with "x"s.

EXPLANATION

Total minutes Naomi has at her disposal is 45 minutes.

The number of minutes she spends getting dressed is

$x$

To find the number of minutes she still has to get ready, we subtract the minutes spent from the total minutes.

The number of minutes she still have to get ready is

$(45 - x) \: minutes$

If a frozen yogurt has 75 calories in 2 oz, how many are in 8 oz of yogurt?

irina [24]

Answer:

The answer would be 300 calories

Step-by-step explanation:

To find the amount of calories in 8 ounces we need to make the ounce amount the same. Let x equal the number of calories.

75/2=x

To get to 8 ounces we need to multiply the bottom by 4. and what we do to the bottom we do to the top.

75*4/2*4=x

multiply

300/8=x

There are 300 calories in 8 ounces.
