B

Answers

Answer 1

Answer:

[tex]AC = 9cos(45)[/tex]

[tex]BC = 9 sin(45)[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Select the equations that solves the unknown lengths

From the attachment, the unknown lengths are:

AC and CB

Where

[tex]AB = 9[/tex]

To calculate AC, we make use of cosine rule

[tex]cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]cos(45)= \frac{AC}{9}[/tex]

Make AC the subject

[tex]AC = 9*cos(45)[/tex]

[tex]AC = 9cos(45)[/tex]

To solve for BC, we make use of sine rule

[tex]sin\theta = \frac{Opposite}{Hypotenuse}[/tex]

[tex]sin(45)= \frac{BC}{9}[/tex]

Make BC the subject

[tex]BC = 9 * sin(45)[/tex]

[tex]BC = 9 sin(45)[/tex]

Answers

The answer is B. Hope this helps

The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

What is quadrilateral?

It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.

We have:

In the diagram below, OP is circumscribed about quadrilateral ABCD.

In a quadrilateral, the sum of the opposite angles is equal to 180 degree

x + 20 + 110 = 180

x + 130 = 180

x = 50

Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

Find tan 30°

Answers

Answer:

[tex]tan(30) = \frac{A}{B}[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find tan(30)

Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B

So [using tangent identity]:

[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

This gives:

[tex]tan(30) = \frac{A}{B}[/tex]

11cm by 6 cm rectangle

Answers

Answer:

Question unclear.

If the question was about the perimeter of the rectangle, it is calculated as:

= (Length * 2) + (Height * 2)

= (11 * 2) + (6 * 2)

= 22 + 12

= 34 cm

If the question was bout Area, the area is:

= Length * width

= 11 * 6

= 66 cm²

Which of the following is a solution of the system 2x + y = 9 and 3x + 5y = 19.​

Answers

2x+y=9

3x+5y=19

I will do this problem in 2 ways. I.)Substitution II.)Elimination

Solution I.) Substitution

We can subtract 2x from both sides in the first equation.

y=9-2x

Now we can substitute the y in the second equation with 9-2x

3x+5(9-2x)=19

-7x+45=19

-7x=-26

x=26/7

y=9-2(26/7)=11/7

Solution II.)Elimination

We can multiply both side of first equation by 5 to get a 5y in both equations.

10x+5y=45

Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.

(10x+5y)-(3x+5y)=45-19

7x=26

x=26/7

2*26/7+y=9

y=11/7

Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.

What is the area of 19 centimeters?

Answers

The Awnser is 7.48 inches

Let's break this up:

Radius: 19

Diameter: 38

Circumference: 119.4

So...

The area of a circle with radius 19 is 1134

A = πr2 = π(d

2

)2 A = C2

π = 3.1415

A = area

C = circumference or perimeter

r = radius, d = diameter

SOLUTION STEPS:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·192 = 1134 square cm(*)

Area of a circle in terms of diameter:

Area = π·(d

2

)2 = 3.14·(38

2

)2 = 3.14·(19)2 = 1134 square cm(*)

Area of a circle in terms of circumference:

Area = C2

= 119.42

= 14256.36

(4·3.14)

= 14256.36

12.56

= 1134 square cm(*)

(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Result in other units of area:

A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:

1.134 × 10-7 square kilometers (km²)

0.1134 square meters (m²)

1134 square centimeters (cm²)

1.134 × 105 square millimeters (mm²)

4.3784 × 10-8 square miles (mi²)

0.135625 square yards (yd²)

1.22063 square feet (ft²)

It’s “D” if you use the rule “y/x” (division) they all equal -4 if you do x/y then they all equal -0.25 but you also have to look at wether they go through the origin if it does then it is proportional, so it’s “D.”

The ratio of the weight of an object on Planet A to the weight of the same object on Planet B is 100 to 3. If an elephant weighs 5000 pounds on Planet​ A, find the​ elephant's weight on Planet B.

Answers

150. Divide 5000 by 100 and you get 50. Multiply 3 by 50 and you get 150.

Answer:

one way to solve this question is to realize that every 100 pounds on planet A equals only 3 pounds on planet B.

 

So, 5000 pounds divided by 100 = 50. Then that number times 3 will give the weigh on planet B which is 150 pounds.

 

Algebraically, 100/3 = 5000/x; when we cross multiply, we get 15000/3 = x; x = 150

What is the chance of drawing a card with a heart on a standard deck if I can draw 2 cards?​

Answers

Answer:

The chances of drawing a heart are therefore 1352 (which reduces to 14 . If we draw another card without replacing the first card, what are the chances of drawing a second heart? There are now 12 hearts in the deck out of 51 cards total and so the odds are 1251 (which reduces to 417 ).

Step-by-step explanation:

So we know that in a 52 card deck, there are 13 hearts, so our probability of drawing a heart on the first try is 13/52.
