y is part of a right angle on line AB

a right angle = 90 degrees

90-47 = 43 degrees

y = 43 degrees

a straight line = 180 degrees

180-47 = 133 degrees

x = 133 degrees

There are some red and blue balls in a bag of 21 balls and the probability of picking 2 red balls out in a row is 1/14 how many

Over [174]

Answer:

6 red balls

Step-by-step explanation:

The probability in the first pick

6/21

The probability in the second pick (without replacement)

5/20

the requested probability

(6/21)(5/20) = 30/420

simplification

30/420 = 3/42 = 1/14

Hope this helps

The dotted line represents the mid segment of the trapezoid. Find the value of X

Ganezh [65]

Given:

Given that the bases of the trapezoid are 21 and 27.

The midsegment of the trapezoid is 5x - 1.

We need to determine the value of x.

Value of x:

The value of x can be determined using the trapezoid midsegment theorem.

Applying the theorem, we have;

$Midsegment = \frac{b_1+b_2}{2}$

where b₁ and b₂ are the bases of the trapezoid.

Substituting Midsegment = 5x - 1, b₁ = 21 and b₂ = 27, we get;

$5x-1=\frac{21+27}{2}$

Multiplying both sides of the equation by 2, we have;

$2(5x-1)=(21+27)$

Simplifying, we have;

$10x-2=48$

Adding both sides of the equation by 2, we get;

$10x=50$

Dividing both sides of the equation by 10, we have;

$x=5$

Thus, the value of x is 5.

You received a $100 gift certificate to a clothing store. The store sells T-shirts for $12 and dress shirts for $21. You wan

Kay [80]

Answer:

3 dress shirts and 3 T-shirts

4 dress shirts and 1 T-shirt

Step-by-step explanation:

You must spend at least $93 and no more than $100.

2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money

2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left

3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works

4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works

5 dress shirts: $105 too much money

Answer:

3 dress shirts and 3 T-shirts

4 dress shirts and 1 T-shirt

a man buys a dozen cameras for $1800. He sells them at a profit of $36 each. Express his profit as a percentage of his selling p

Helga [31]

First of all, we need to deduce the price of a single camera:

$\dfrac{1800}{12}=150$

Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have

$36 = 150\cdot\dfrac{x}{100}$

This equation literally says: 36 is x-percent of 150. And we need to solve for x:

$x=\dfrac{36\cdot 100}{150} =24$
