Answer:

x=12. B=52

Step-by-step explanation:

In ∆BCD,

<C=45

<D=7x-1

<B=3x+16[as this diagram is a parellelogram so DE II BC so <CBD=<BDE=3x+16 bcz alternate interior angle]

interior angle of triangle=180 degree

<B+<C+<D=180

3x+16 + 45 + 7x-1 = 180

10x + 60=180

10x =180-60

x=120/10

x=12 degree

m<B =3x+16

=3(12)+16

=36+16

m<B = 52 degree

128 times out of 200

Answer:

a. x = 4.8989794855663561963945681494118 or 4.9 rounded

b. x = 8.6023252670426267717294735350497 or 8.6 rounded

Step-by-step explanation:

7² - 5² = x²

49 - 25 = x

49 - 25 = 24

√24 = 4.8989794855663561963945681494118

7² + 5² = x²

49 + 25 = x

49 + 25 = 74

√74 = 8.6023252670426267717294735350497

Answer:

721.64

Step-by-step explanation:

32.7*26.3=860.01

13.7*10.1=138.37

860.01-138.37=721.64

721.64 mi^2

Step-by-step explanation:

Area of the large rectangle A2 is

A2 = (32.7 mi)(26.3 mi) = 860.01 mi^2

Area of the small rectangle A1 is

A1 = (10.1 mi)(13.7 mi) = 138.37 mi^2

Therefore, the area of the shaded region is simply the difference between A2 and A1:

Area (shaded) = A2 - A1

= 860.01 mi^2 - 138.37 mi^2

= 721.64 mi^2

Answer:

See below for answers and explanations

Step-by-step explanation:

Problem 1:

A standard deck of cards contains 52 cards, consisting of 13 spades. If you select only one randomly, the probability of that occurring would be 13/52 or 1/4. Since there are only 26 red cards in a standard deck, then the probability of selecting a red card would be 26/52 or 1/2. Because the two events are independent of each other, their probabilities are multiplied. Therefore, the probability of selecting a spade, and then replacing it in hopes of drawing a red card is (1/2)(1/4) = 1/8.

Problem 2:

We are selecting a spade and then another spade while NOT replacing the first spade (remember that these events are independent of each other also). This means that the total card count will change by picking up the second card. Therefore, the probability of selecting a spade, followed by another spade, is (13/52)(12/51) = 156/2652 = 1/17.

Answer:

I'm gonna go with b p.s: sorry if im wrong

Step-by-step explanation:

The Situation described in option A models best the given expression

The given expression is:

[tex]\frac{1}{2} *\frac{1}{6}[/tex]

A fraction is part of a whole.

A)Pablo spent 1/2 hour practising the trumpet, he spent 1/6 of that time practising his scales.

This means he spent [tex]\frac{1}{2} *\frac{1}{6}[/tex] hours i.e. [tex]\frac{1}{12}[/tex] hours while practising his scales.

So, option A best models the expression [tex]\frac{1}{2} *\frac{1}{6}[/tex].

B)This option is concerned with [tex]\frac{1}{2} +\frac{1}{6}[/tex]

C)This option is concerned with [tex]\frac{1}{2} /\frac{1}{6}[/tex]

D)This option is concerned with [tex]\frac{1}{2} -\frac{1}{6}[/tex]

Hence, option A best models the expression [tex]\frac{1}{2} *\frac{1}{6}[/tex].

Answer:

No, because water temperature is confounded with brand of detergent.

Step-by-step explanation:

There is a very possible chance of allowing a third or confounding variable to have creepwd into the research. The aim was to investigate which of two detergents prevents color from fading. Hence, the test for both detergents should be carried out under the same research condition. However, with adoption of different water temperature for each of detergent A and B, there may be a relationship between fading and water temperature which is not what are trying to investigate. This difference in temperature will thus cause a spurious relationship in our research. Hence, water temperature has been confounded with detergent brand, making this experimental design a bad one.

1 Let x=1x=1.

2\times 1\times 4=8

2×1×4=8

2 Simplify  2\times 12×1  to  22.

2\times 4=8

2×4=8

3 Simplify  2\times 42×4  to  88.

8=8

8=8

Step-by-step explanation:

What is the Value of the expression 3 (2x - 4) when x = -3?​

2 Divide both sides by 88.

x=1

Answer:

Assume that the two digits are x and y (x is at ones position and y is at tens position)

if we subtract the digit of a two digit number, we get 4.

this means,

x-y=4    ..................... (1)

if we interchange the digits of the number and subtract the new number from the original number we get 44.

this means,

old no. 10y+x

new no. 10x+y

10y+x-(10x+y)=44

10y+x-10x-y=44

9y-9x=44    ........................... (2)

solve the two equations:

id these two equations are solved, we get no solution.

Answer:

x = 8

Step-by-step explanation:

It is given that the two polygons are similar, one property of similar polygons is that if one were to multiply each side length by a certain number (referred to as the ratio of similitude), they would get the side length of the corresponding side on the other polygon. To find the ratio one has to divide the side length of one polygon by its corresponding side length in the other polygon.

30 ÷ 25 = 1.2

Set up an equation by multiplying one side length by the ratio of similitude, set it equal to its corresponding side length in the other polygon;

1.2 (35) = 4x + 10

Simplify,

42 = 4x + 10

Inverse operations,

42 = 4x + 10

32 = 4x

8 = x

Answer:

Step-by-step explanation:

Use proportions to solve this and the similarity from smaller side to corresponding larger side:

[tex]\frac{s}{l}:\frac{25}{30}=\frac{35}{4x+10}[/tex] and cross multiply to solve for x:

1050 = 25(4x + 10) and

1050 = 100x + 250 and

800 = 100x so

x = 8

Answer:

r = 105

Step-by-step explanation:

Given quadratic equation:

x² − 9x − 6

Quadratic formula is given by:

(-b ± √b² - 4ac) ÷ 2a

For the equation: x² - 9x - 6

a = 1, b = -9 and c = -6

Substitute in the quadratic formula:

(-b ± √b² - 4ac) ÷ 2a

(-(-9) ± √(-9)² - 4(1*-6)) ÷ 2*1

= 9 ± √105 / 2

The solution of x² − 9x − 6 is expressed as 9 plus or minus the square root of r, all over 2

Therefore, the value of r is 105

Answer:

Break-even point in units= 571 hamburgers

Step-by-step explanation:

Giving the following information:

The cost of making a hamburger is 10.75 and the selling price is 16. The fixed expenses for the month are 3000.

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 3,000 / (16 - 10.75)

Break-even point in units= 571 hamburgers

Answer:
