Divide the figure into 3 recdtangles and one triangle.  Calculate the area of each and take the sum.

I realize after looking at the image that one could have made only two rectangles and gotten the same result.

Answer:

The answer is "20".

Step-by-step explanation:

Given value:

[tex]\to Z_{critical}= 1.96\\\\\to {StdDev} = standard\ deviation = 50 \\\\\to n= 25\\\\[/tex]

formula:

[tex]\bold{Margin error}= Z_{critical} \times \frac{\text{StdDev}}{\sqrt{n}}\\[/tex]

                       [tex]= 1.96 \times \frac{ 50 }{\sqrt{25}}\\\\= 1.96 \times \frac{ 50 }{\sqrt{5 \times 5}}\\\\= 1.96 \times \frac{ 50 }{{5}}\\\\= 1.96 \times 10 \\\\= 19.6 \\\\= 20[/tex]

Answer:

38 square feet

Step-by-step explanation:

How do we find the area of a circle?

  ❖ The area of a circle is πr², where r = radius. For this case, we're going

       to approximate pi as 3.14.

How do we find the radius given diameter?

  ❖ We are given the diameter of Claire's hot tub as 7 feet. The diameter

       is 2x the radius, so we divide 7 by 2 to get the radius, which is 3.5

       feet.

Solving

Therefore, the answer is 38 square feet. Have a lovely rest of your day/night, and good luck with your assignments! ♡

The number of terms in the given arithmetic sequence is 27 so option (C) will be correct.

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

The arithmetic progression has wider use in mathematics for example sum of natural numbers.

Natural number = 1,2,3,4,5,6,7,8...

Now it has the same difference between any two consecutive terms d =2-1 = 3-2

Given the AP;

- 92,- 88, -84, ...,12.

First term (a) = -92

Common difference(d) = -88 + 92 = 4

The nth term or last term = 12

Nth term is given as ;

⇒ a + (n - 1)d

12 = -92 + (n - 1)4

n - 1 = 26

n = 27

Hence "The number of terms in the given arithmetic sequence is 27".

Answer:

5 months

Step-by-step explanation:

Create an Equation:

m=months

Joe- 40m

Mike- 20m +100

Make each equation equivalent:

40m=20m+100

Solve:

40m-20m=100

20m=100

m=5

If you plug it back in, the equation is satisfied:

40(5)=20(5)+100

200=100+100

200=200

Answer:

24 monkeys are in the tree

Step-by-step explanation:

We solve it by writing [tex]\frac{60}{100}[/tex] times [tex]\frac{40}{1}[/tex]

Why is it over 100? Because every percent is out of 100!

[tex]\frac{60}{100}[/tex] X [tex]\frac{40}{1}[/tex] (your equation)

60 times 40 = 2400 and 100 times 1 = 100, We get, [tex]\frac{2400}{100}[/tex],

Lastly, we simplify the fraction by 100 on each side:

[tex]\frac{2400}{100}[/tex] / [tex]\frac{100}{100}[/tex]

you get 24

Answer:

Step-by-step explanation:

The equation is

Salary = 11 * x              Where x is the number of hours.

salary = 143

hours = 11

x = ?

143  = 11x                     Divide both sides by 11

143/11 = 11x/11

13 = x

So to get 143 he works for 13 dollars / hour

salary = 13 * x

salary = 91

13 x = 91

13x/13 = 91/13

x = 7

He must work 7 hours to get 91 dollars.

Jim made 143 dollar for 11 hours of work at the same rate how many hours would he have to work to make 91 dollar

Given:

To Find:

Solution:

We can solve this question using two methods Unitary Method and Method of proportion.

Unitary Method -

For $143 he work 11 hours

For $1 he work [tex]\dfrac{11}{143}[/tex] hrs

For $91 he works [tex]\dfrac{\cancel{11}} {\cancel{143}\: \: \cancel{13}}[/tex] × [tex]\cancel{91}\: \: 7 [/tex]hrs

= 7 hours

He must work 7 hours to get $91.

[tex] \ {\rule{50mm}{3pt}}[/tex]

Method of proportion -

He work 'x' hours for $91. (x as no. of hrs)

[tex] \left[\begin{array}{c | c}\ \bf{Salary} & \bf{Number \: of \: hrs} \\ \sf{143 \: dollar} & \sf{11hrs} \\ \sf{91 \: dollar}& \sf{x}\end{array} \right][/tex]

143 : 91 :: 11 : x

Product of mean = Product of extreme

143 × x = 91 × 11

→ x = [tex]\dfrac{91 × 11}{143}[/tex] = 7hrs

He must work 7 hours to get $91.

The figure shown would represent a parallelogram if opposite sides are parallel and congruent

It is true that the figure is a parallelogram

The coordinates of the figure are given as:

O = (0,0)

P = (a,b)

S = (a + c,b)

T = (c,0)

Vertices O and T are on the same horizontal level, because they have the same y-coordinate

The above is also applicable to vertices P and S

By observation, we have the following distances:

PS = c

OT = c

This means that the opposite sides are parallel and congruent

Hence, the figure is a parallelogram

Answer:

(a) y = 1/4x - 4

(b) y = -4x + 17

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

(a)

Parallel lines have the same slope but different y-intercepts.

m = 1/4x

y = 1/4x + b

-2 = 1/4(8) + b

-2 = 2 + b

b = -4

y = 1/4x - 4

(b)

Perpendicular lines have the negative reciprocal slope.

m = -4

y = -4x + b

1 = -4(4) + b

1 = -16 + b

b = 17

y = -4x + 17

Answer:

(a) y = 1/4x - 4

(b) y = -4x + 17

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Parallel lines have the same slope but different y-intercepts

Perpendicular lines have the negative reciprocal slope.

Answer:

The equation of a line is given by y = mx + c; where m is the slope.

The given equation is y = 5/4 x - 7/4.

Therefore, the slope is 5/4.

Step-by-step explanation:

I think i already answered this question, but i will rewrite it again! since the angles 'x' and '2x+9' add up to become a supplement angle or a straight line.

We can establish the relation which says that the sum of these two angles is equal to 180.

[tex]x + 2x + 9 = 180[/tex]

[tex]3x + 9 = 180[/tex]

[tex]3x = 180 - 9[/tex]

[tex]3x = 171[/tex]

The scale factor used to create the cross section is 1/3. The cross section has a base side length of 77 meters.

An equation is an expression that shows the relationship between two or more numbers and variables.

The height of the dilated pyramid = 144 m - 96 m = 48 m

Scale factor of dilation = 48 m / 144 m = 1/3

The side length of dilated pyramid = (1/3) * 231 m = 77 m
