Answer:

SRQ=24°

QTS=30°

RST=60°

RSQ=30°

Step-by-step explanation:

All angles in a triangle will always=180.

First we will find RQT

30+24+Q=180

Subtract 54 from each side

Q=126

Since All lines meet in the middle at Q, then each if those angle measures are equal.

We'll find SRQ first:

We don't know S but we know R is 24 and Q is 126

126+24+S=180

subtract 150

S=30°

QTS:

It tells us that T is 70° so that's all we need for this

RST:

We found half of S which was 30, so 30•2= 60 so RST=60

RSQ:

We already found the half of S which was 30°

Answers

Answer:

6.98

Step-by-step explanation:

The answer would be 6.98 after subtracting 8.92 from the 15.9 after applying arithmetic operation.

What are arithmetic operations?

The study of numbers and their operations, which are relevant to all other fields of mathematics, is part of the discipline of arithmetic operations. Addition, subtraction, multiplication, and division are the basic operations that make up this system.

It is given that:

The number expression is:

= 15.9-8.92

As we know from the definition of the arithmetic operation: Addition, subtraction, multiplication, and division are the basic operations that make up this system.

In the expression subtract 8.92 from the 15.9

After applying the arithmetic operation:

= 6.98

Thus, the answer would be 6.98 after subtracting 8.92 from the 15.9 after applying the arithmetic operation.

Mr. Stokes bought 6 1/2 pounds of meat for a party. He used 2 1/4 pounds of meat to make tacos. The rest he used to make 1/4 pound burgers. How many burgers did Mr. Stokes make?

Answers

9514 1404 393

Answer:

  17

Step-by-step explanation:

The remaining amount of meat is ...

  6 1/2 - 2 1/4 = 4 1/4 = 17/4 . . . pounds

The number of 1/4 pound burgers that can be made with that amount of meat is ...

  (17/4)/(1/4) = 17/1 = 17

Mr. Stokes made 17 burgers.

Emma is 10 years old. she asked her father how old he is. her father answered, "when you are my age I will be 70." how old is Emma's father.

Answers

Answer:

40

Step-by-step explanation:

Emma age: yE = 10 + x   (x is timeline)

Father age: yF = A + x (x is timeline, A is Father age today)

in time x1: Emma will be A years old, and Father will be 70 years old.

yE (x1) = 10 + x1 = A

yF (x1) = A + x1 = 70

System of equations with unknown values: x1 and A.

substract equation 1 - equation 2:

10 - A = A - 70 ⇒ 80 = 2A ⇒ A = 40

So, father is 40 years old now

Emma's father is 40 years old

Let the age of Emma father be y

Age of emma = 10 years

In x years time;

Emma age will be 10 + xFathers age will be y + x

If in x1 years time, Emma will be y years old and his father will be 70 years old

Emma age: yE = 10 + x   (x is timeline)

Emma's current age will be 10 + x = yHis father;s current age will be y + x = 70

Solving both equations simultaneously;

10 - y = y - 70

10+70 = y + y

80 = 2y

2y = 80

y = 80/2

y = 40 years

Hence Emma's father is 40 years old

Find the coordinates of the point where y-4x=1 crosses the y axis

Answers

Answer:

(a) (-1/4,0)

(b) k = (10-c)/2

Step-by-step explanation:

(a) A point passing through the y-axis is the same as finding the y-intercept.

[Move terms to right-hand side; y = mx + b form]

y = 4x + 1

[Find x, when y = 0]

0 = 4x + 1

-1 = 4x

-1/4 = x

At x = -1/4, y = 0 therefore the point: (-1/4,0) crosses the y-axis.

(b) To find the value of k in (k,10), we need to find x. Given y= 10 x=k c=constant

[Find x by plugging in known values]

Using y = 2x + c,

10 = 2k + c

10 - c = 2k

(10-c)/2 = k

Volume: [tex]339.29cm^{3}[/tex]

Step-by-step explanation:

The formula for the volume of a cylinder is: [tex]\pi r^{2}h[/tex]. Since we are given the diameters instead of the radius, we divide the diameters by 2 to get the radius.

∴ The expression for the volume of the large cylinder after the hole was removed is [tex]\pi (\frac{D}{2})^{2}h - \pi(\frac{d}{2})^{2}h[/tex]

Approximate volume:

Substitute the numbers in:

[tex]\pi(\frac{8}{2})^{2}\times9-\pi(\frac{4}{2})^{2}\times9=339.29cm^{3}[/tex] (to the second decimal place)

∴ The volume of the big cylinder after removing the cylindrical hole is approximately [tex]339.29cm^{3}[/tex]

Answer:

Step-by-step explanation:

9514 1404 393

Answer:

  x = -1

Step-by-step explanation:

Putting the entire equation in decimal form, we have ...

  2.1x + 1.8 = 0.3x

Subtracting 0.3x gives ...

  1.8x +1.8 = 0

Dividing by 1.8, we get ...

  x + 1 = 0

So, the solution is ...

  x = -1 . . . . . . subtract 1 from both sides.

_____

Additional comment

Sometimes, when all of the numbers in the equation are divisible by the coefficient of x, it works out well to do that division before separating variables and constants. The other way this could have been solved is ...

  subtract 1.8  ⇒  1.8x = -1.8

  divide by 1.8  ⇒   x = -1

No, you will not be able to buy 3 more CDs. Question 3 c. Explain your reasoning for part (b). Each CD costs $ at the regular price, so 3 CDs would cost $ .

Answers

Answer:

$7.6 ;

No, you will not be able to buy 3 more CDs

$9.5

$28.5

Step-by-step explanation:

Given that :

Cost of 4 CDs = $30.40

Cost per CD is equal

Sale price = 80% of original price

Price p per CD:

Cost of 4 CDs / number of CDs

$30.40 / 4

= $7.6

2)

No, you will not be able to buy 3 more CDs

If x = original price

80% of x = 7.6

0.8x = 7.6

x = 7.6 / 0.8

x = $9.5

$9.5 * 3 =$28. 5

Hence, $25 can't buy 3 CDs the next day (28.5 > $25)

In ΔUVW, u = 44 inches, ∠W=56° and ∠U=117°. Find the length of v, to the nearest inch.

Answers

Answer:

The length of v is 6 inches

Step-by-step explanation:

Here, we want to calculate the length of v to the nearest inch

The best way to go about this is to use the sine rule

But before we proceed, we need the measure of angle V

Mathematically, since we have a triangle

W + U + V = 180

This is the sum of angles in a triangle

56 + 117 + V = 180

V = 180-56-117

V = 7 degrees

so we proceed to use sine rule to get the length of v

Mathematically;

v/Sin V = u/Sin U

Thus;

v/sin 7 = 44/sin 117

v = 44sin 7/sin 117

v = 6.018

This is approximately 6 inches

Find the circumference and the area of a circle with radius 7ft .
Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

Answers

Answer:

C=43.96 ft.

A=153.86 ft.^2

Step-by-step explanation:

for circumference, use C=2πr

for area, use A=π[tex]r^{2}[/tex]

The circumference and the area of a circle with radius 7 feet are 43.96 feet and 153.86 square feet, respectively.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

where (h, k) is the center and r is the radius of the circle.

Given:

A circle with radius 7 feet.

Then the circumference of the circle,

= 2πr

= 2(3.14)(7)

= 43.96 feet.

The area of the circle,

= πr²

= (3.14) (49)

= 153.86 square feet.

Therefore, circumference is 43.96 feet and area is 153.86 square feet.

Kate is 4 years older than Bob. If the sum of their ages is 28, what are the ages of
Kate and Bob?

Answers

Bob is 24 Kate is 28

Answer:

Kate is 16, Bob is 12

Step-by-step explanation:

Since Kate is 4 years older than Bob, Kate's age is represented by the following equation:

B+4=K

Bob's age is just B

Now, the sum of their ages is 28, which means we add Kate's and Bob's age:

Instead of writing K+B=28, we would write the equation with the same variable:

B+4+B= 28

(B+4= Kate's age)

add like terms

2b+4=28

subtract 4 from both sides

2b=24

divide by 2

b=12

12 is Bob's age and to find Kate's age, we add 4

Kate is 16.

If the radius of this Ferris wheel is 125 feet and the angle between each seat is 36°,
then what is the height of the Ferris wheel seat at point B if the bottom of the wheel is
20 feet off the ground? (Round to the nearest tenth)

Answers

Answer:

The height of the seat at point B above the ground is approximately 218.5 feet

Step-by-step explanation:

The given parameters are;

The radius of the Ferris wheel, r = 125 feet

The angle between each seat, θ = 36°

The height of the Ferris wheel above the ground = 20 feet

Therefore, we have;

The height of the midline, D = The height of the Ferris wheel above the ground + The radius of the Ferris wheel

∴ The height of the midline = 20 feet + 125 feet = 145 feet

The height of the seat at point B above the ground, h = r × sin(θ) + D

By substitution, we have;

h = 125 × sin(36°) + 145 ≈ 218.5 (The answer is rounded to the nearest tenth)

The height of the seat at point B above the ground, h ≈ 218.5 feet.
