Identify the volume of the hemisphere in terms of π. HELP ME PLEASE!!! THE RED IS THE ONE I GOT WRONG!

Answer:

The two angles are equal where the unequal sides meet.

It can be viewed as a pair of congruent triangles with a common base.

It has 2 diagonals that intersect each other at right angles.

The longer or main diagonal bisects the other diagonal.

A kite is symmetrical about its main diagonal

Step-by-step explanation:

x²= (5.3)²+(12.8)²

= 28.09 + 163.84

= 191.93

x =√191.93 = 13.85

Answer:

13.85

Step-by-step explanation:

√(12.8)²+(5.3)²

=13.85

Answer:

126.5 cm^2

Step-by-step explanation:

You can divide into 2 shapes, a triangle and a rectangel.

The Rectangel:

The Triangle (height × groundline /2 = area)

Together:

88 + 38.5 = 126.5 cm^2

Answer: each pencil would cost 0.36¢

Step-by-step explanation: first, divide 12.82 by 36 to get the unit rate. The answer should be 0.356111111. Now round that to the nearest cent. 0.356111111~0.36

Answer:

Each pencil is worth 36 cents

Step-by-step explanation:

To do the problem we have to find the unit price which is [tex]Total Price/Total Units[/tex]

Once you have that round the answer then the answer is 0.36

Answer:

arc BD = 148°

Step-by-step explanation:

The arc BC  is twice the inscribed angle BDC

arc BC = 2 × 56° = 112°

The 3 arcs sum to 360° , then

arc BD = 360° - (100 + 112)° = 360° - 212° = 148°

Answer:

y= -1x+ 3

Step-by-step explanation:

y= Mx+ C

m= gradient or slope

m= y2-y1/ x2-x1

=5-(-2)/-2-5

=7/-7

=-1

C= intercept on the y-axis

=3

therefore y= -1x + 3

Answer:

[tex]f(x) = \frac{2x}{5y+6}[/tex]

Step-by-step explanation:

Answer:

Below!

Step-by-step explanation:

f(x) = 2x/5x+6

Sub y for f(x) : y = 2x/5x+6

Swap x and y : x = 2y/5y+6

Multiply both sides by 5y+6 : 2y = (5y + 6) x

Distribute x : 2y = 5xy + 6x

Change sign : 2y - 5xy = 6x

Factor out y : (2-5x)y = 6x

Divide both sides by 2-5x : y = 6x/2-5x

Substitute for y : f^-1(x) = 6x/2-5x

Answer: f^-1(x) = 6x/2-5x

That's the best I could do with my current math knowledge, I hope it makes sense :)

- 4 × ( n + 8 ) = - 12

Divide both sides by - 4

( - 4 × ( n + 8 ) ) ÷ ( - 4 ) = - 12 ÷ ( - 4 )

Simplification

( n + 8 ) = 3

n + 8 = 3

Subtract both sides - 8

n + 8 - 8 = 3 - 8

n = - 5

Answer:

6 feets

Step-by-step explanation:

Height of ramp = 7feets

θ = 28°

Length of ramp = x

Using trigonometric relation :

Sin θ = opposite / hypotenus

Sin 28 = 3 / x

0.4694715 = 3 / x

0.4694715x = 3

x = 3 / 0.4694715

x = 6.39 feets

The length of the ramp = 6 feets

Answer:

her salary after 8 years is $26,602

Step-by-step explanation:

Given that

Fiona salary is $21,000

She received 3% raise each year

We need to find her salary after 8 years

So, here we apply the future value formula

i.e.

= Present value × (1 + rate of interest)^number of years

= $21,000 × (1 + 0.03)^8

= $21,000 × 1.03^8

= $26,602

hence,  her salary after 8 years is $26,602

Answer:

Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.

Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.

Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

The sum of the arithmetic series is:

893

What are arithmetic progressions?

An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.

An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.

Solution:

Given:

a1 = 11, a2 = 15 and an=83

Step-1:

d= a2 ₋ a1

d= 4

Now, an = a ₊ (n ₋ 1)d

          83 = a ₊ (n ₋ 1)4

          83 = 11 ₊ 4n ₋4

          83 = 7 ₊ 4n

         4n = 83 ₋ 7

          n = 19

Step-2:

Now, Sn = n/2 (a1 ₊ an)

         Sn = 19/2 (11 ₊ 83)

         Sn = 19/2 ₓ 94

         Sn = 893

Hence we get the answer as 893

The least value, first quartile, median, third quartile, and greatest value of the data are 4, 5, 8, 9.75 and 15 respectively.

The first step is to arrange the number in ascending order: 4, 5, 5, 6, 8, 8, 9, 10, 12, 15

The median is the number in the center of the data set. The number is 8.

First quartile = 1/4 x (n + 1) = 2.75 number : 5

Third quartile = 3/4 x (n + 1) = 8.75 = 9.75
