Answer:

28

Step-by-step explanation:

50+4= 54

54/2=28

Answer:

2a - 4 = 50

Step-by-step explanation:

Less than means that you subtract 4.

Twice a number just means that you multiply a number by 2.

And we know that all of that equals 50.

If you want to solve it..

2a - 4 = 50

    +4     +4

-----------------

2a = 54

Divide both sides by 2. 54/2 = 27

a = 27

Answer:

a. m<CBA = m<DBA because of the definition of an angle bisector (angle bisector cuts the angle in half) We are also told that segment BD and Segment BC are congruent.

We don't know if segment AC and AD are congruent so we can't say those angles (the other two) are congruent.

b. point A and B will stay fixed because they are colinear to segment AB (on the same line)

c. Those two are needed because If those are true we can prove that they are congruent by SAS (Side Angle Side)

d. the reflection an prove that the lines and angles are congruent.

Answer:

Thus, the original price of the pair of shoes was $100.

Step-by-step explanation:

Percentages

After a 60% discount, the sale price is now valued at 100-60=40% of its original price.

If the sale price is $40, then the original price is calculated as

$40 / 40 * 100 = $100

Thus, the original price of the pair of shoes was $100.

Verify applying 60% discount:

$100 - 60*$100/100 =  $40

Answer:

Area of [tex]\triangle[/tex]ACD = 4 [tex]ft^2[/tex]

Area of [tex]\triangle[/tex]ABC = 16 [tex]ft^2[/tex]

Step-by-step explanation:

Given that:

D is a point on AB.

and ABC is a triangle.

AD:DB = 1 : 3

Area of [tex]\triangle[/tex]CDB = 12 [tex]ft^2[/tex]

Kindly refer to the attached image as per the given dimensions and values.

To find:

Area of [tex]\triangle[/tex]ACD and Area of [tex]\triangle[/tex]ABC = ?

Solution:

Formula for area of a triangle = [tex]\frac{1}{2}\times Base \times Height[/tex]

The altitudes of triangles [tex]\triangle[/tex]CDB and [tex]\triangle[/tex]ACD are equal in dimensions.

Therefore the area of triangles [tex]\triangle[/tex]CDB and [tex]\triangle[/tex]ACD will be equal to the ratio of their bases.

Area of [tex]\triangle[/tex]ACD : Area of [tex]\triangle[/tex]CDB = AD: DB = 1 : 3

[tex]\Rightarrow[/tex] Area of [tex]\triangle[/tex]ACD = [tex]\frac{12}{3} = \bold{4 ft^2}[/tex]

Area of [tex]\triangle[/tex]ABC = Area of [tex]\triangle[/tex]ACD + Area of [tex]\triangle[/tex]CDB = 12 + 4 = 16 [tex]ft^2[/tex]

Therefore, the answer is:

Area of [tex]\triangle[/tex]ACD = 4 [tex]ft^2[/tex]

Area of [tex]\triangle[/tex]ABC = 16 [tex]ft^2[/tex]

answer

7711.07

Step-by-step explanation:

The chef uses 7,711.03 grams each day at a restaurant.

The methodology to convert Pounds to Grams is relatively simple. To convert Pounds to Grams, you must multiply the unit by 453.59.

For example, if you have to convert 5 Pounds to Grams, you need to multiply 5 by 453.59.

A chef at a restaurant uses 17 pounds of butter each day.

We have to determine the number of grams the chef uses each day.

Since 1 pound (lb) is equal to 453.59 grams (g).

So 17 pounds = 453.59 × 17 = 7,711.03 grams

Thus, the chef uses 7,711.03 grams each day.

The least common multiple is divisible by both a and b. The two numbers below have a least common multiple of 48 is 3 and 16.

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

The two numbers below have a least common multiple of 48 are,

3 and 16 ⇒ 3×16=48

Hence, the two numbers below have a least common multiple of 48 is 3 and 16.

10. The part of the expression that represents the product of two factors would be 6.7s because 6.7 is being multiplied by s, and a product is an answer to a multiplication problem

Step-by-step explanation:

9. The part of the equation that represents a quotient is (10÷2). 10.  The part of the equation that represents the product of two elements is 6.7s.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The expression is given in the question, as follows:

6.7s - (10÷2) +15

9. The part of the equation that represents a quotient is (10÷2) since the division equation is solved inside the parenthesis and a quotient is the answer to a division problem.

Answer:

The required probability is 0.09875

Step-by-step explanation:

From the given information;

the probability of repairing the telephones = 0.70

the probability of the replaced = 0.30

Suppose we consider  Mto denotes the telephone that is submitted for service while under warranty and must be replaced.

Then;

p = P(S) = P(replaced | submitted) P(submitted)

= 0.30 × 0.20

= 0.06

Now, the probability that exactly two will end up being replaced under warranty given that it assumes  a binomial distribution where n = 10 and p = 0.06

[tex]P(X=2)=\bigg (^{10}_{2}\bigg) 0.06^2(1-0.06)^{10-2}[/tex]

[tex]P(X=2)=\dfrac{10!}{2!(10-2)!}\times 0.06^2\times (0.94)^{8}[/tex]

[tex]\mathbf{P(X=2)=0.09875}[/tex]

Answer:

x = 45

Step-by-step explanation:

Because these are two congruent triangles inside of each other we can set up an equivalency ratio.

25/35 = x/65

Multiply both sides by 65 to get x alone

65 * 25/35 = x/65 * 65

(65 * 25)/35 = x1

1576/35 = x

x = 45

Answer:

We have a 52 card deck:

a. Find the probability that both cards are clubs.

The probability of drawing a club will be equal to the quotient between the number of clubs in the deck divided by the total number of cards in the deck.

We initially have 13 clubs and 52 cards, then the probability of drawing a club in the first draw is:

p1 = 13/52.

Now the probability of drawing a club in the second draw will be:

p2 = 12/51

Where each number is decreased by one because we already drew a card, and that card was a club.

Then the probability of both events happening will be equal to the product of the individual probabilities:

P = p1*p2 = (13/52)*( 12/51) = 0.059

b. Find the probability that the first card is a spade and the second is a club.

Same as before, the probability of first drawing a spade is:

p1 = 13/52

And the probability of drawing a club in the second draw will be:

p2 = 13/51

This case differs from the prior one because for the second draw we have 13 clubs in the deck, and as we already drew one card (that was not a club) the total number of cards in the deck is 51.

Now the joint probability will be:

P = p1*p2 = (13/52)*(13/51) = 0.064
