Hello! answer: 87.92

Step-by-step explanation:

Im a little rusty on these but the answer I believe would be 87.92

2 × 2 × 3.14 = 12.56

2 × 2 × 3.14 = 12.56

4 × 3.14 = 12.56 12.56 × 5 = 62.8

12.56 + 12.56 + 62.8 = 87.92

The triangles shown below are similar. Find the length of QS.

Answers

Answer: The value of QS is 8 cm.

Step-by-step explanation:

First calculating the side QT.

As per given figure:

ΔPQT ≈ ΔRST

[tex]\frac{PQ}{RS}=\frac{QT}{ST}[/tex]

Given:

PQ = 9 cm

RS = 3 cm

ST = 4 cm

Now putting all the given values in the above expression, we get:

[tex]\frac{PQ}{RS}=\frac{QT}{ST}\\\\\frac{9cm}{3cm}=\frac{QT}{4cm}\\\\QT=12cm[/tex]

Now calculating the value of QS.

QT = QS + ST

12 cm = QS + 4 cm

QS = 12 cm - 4 cm

QS = 8 cm

Thus, the value of QS is 8 cm.

Answer:

30000 : 20000

Step-by-step explanation:

Given the ratio

[tex]\frac{1}{10}[/tex] : [tex]\frac{1}{15}[/tex] ( multiply both parts by 30 the LCM of 10 and 15, to clear the fractions )

= 3 : 2

sum the parts of the ratio, 3 + 2 = 5 parts

Divide the amount by 5 to find the value of 1 part of the ratio

50000 ÷ 5 = 10000 ← value of 1 part of the ratio, then

3 parts = 3 × 10000 = 30000

2 parts = 2 × 10000 = 20000

Then

50000 = 30000 : 20000 in the ratio 3 : 2

Carry On Learning (◕ᴗ◕✿)

To find the median or middle, first put the numbers in order from least to greatest.
2,2,2,3,4,6,9,10
Then find the middle number. This set has two numbers since it is an even amount. 3,4
So you add those numbers
3 + 4 = 7
Then divide by 2
7/2 = 3.5
3.5 is the median for this set

I always think of the median of a highway. It is in the middle between both sides.

Find the indicated area of the sector surrounded in bold . Use 3.14 for pi!

Answers

Answer:

75.4 yd²

Step-by-step explanation:

Formula for Area of a sector when the central angle is given in degrees is given as :

θ/360 × πr²

Where:

Central angle = θ = 135°

Radius = r = 8yd

π = 3.14

Hence,

135/360 × 3.14 ×(8yd)²

= 75.36 yd²

Approximately the Area of the sector = 75.4 yd²

Answers

9514 1404 393

Answer:

  BE = 5 cm

Step-by-step explanation:

Your problem statement asks for the length of BC. There is no segment BC. Points B and C are in different triangles.

The length of segment BE can be found from the proportion ...

  BE/DE = AB/CD

  BE = DE·AB/CD = (4 cm)(10/8)

  BE = 5 cm

At the market you can buy 5 bags of apples for $23.60. At the farm you can buy 7 apples for $32.76. Which is the better deal

Answers

Answer:

Market

Step-by-step explanation:

Market : 5 bags = $23.60

Farm : 7 apples = $32.76

Market = $23.60 ÷ 5

= $4.72 each BAG

Farm = $32.76 ÷ 7

= $4.68 each APPLE

Thus, market is the better deal because you will get 5 bags of apple for $4.72 for each bag.

Step-by-step explanation:

Need help with this??? Please!!!

Answers

Answer:

the first option

Step-by-step explanation:

(f-g)(x) simply means to subtract both expressions. really literally.

and we go through it power by power of x.

the highest power/exponent of x is 3 (x³). only f(x) has one.

so, -7x³ is the first part of f-g.

next is x².

11x² - 6x² = 5x², which is the second part of f-g.

next is x.

-8x - (-14x) = -8x + 14x = 6x, which is the third part of f-g.

next is x⁰ (in other words, no x, just a constant).

4 - (-3) = 4 + 3 = 7, which is the 4th part of f-g.

we have no x to the power of -1 or -2, so we have -3

0 - (-4x‐³) = 4x‐³, which is the last part of f-g.

so, it is clearly the first answer option.

10 student failed in both subjects.

Step-by-step explanation:

Since out of 100 students who appeared in grade VIII annual examination of Ram Janaki Secondary School, 60 passed in mathematics, 50 in science and 20 students passed in both subjects, to determine how many failed in both subjects the following calculation must be performed:

(100 - 20) - (60 - 20) - (50 - 20) = X

80 - 40 - 30 = X

40 - 30 = X

10 = X

Therefore, 10 student failed in both subjects.
