HELP PLS ILL GIVE U BRAINLEST OF U ANSWER THE QUESTION IN THE PIC CORRECT PLS ASAP PLS DONT GUESS PLS HELP

Answer:

I believe it's C

Step-by-step explanation:

[tex]\\ \sf\longmapsto Area=30x^2-53x+12[/tex]

[tex]\\ \sf\longmapsto Area=30(3)^2-53(3)+12[/tex]

[tex]\\ \sf\longmapsto Area=30(9)-159+12[/tex]

[tex]\\ \sf\longmapsto Area=270-159+12[/tex]

[tex]\\ \sf\longmapsto Area=111+12[/tex]

[tex]\\ \sf\longmapsto Area=123[/tex]

And

[tex]\\ \sf\longmapsto Base=4x-6[/tex]

[tex]\\ \sf\longmapsto Base=4(3)-6[/tex]

[tex]\\ \sf\longmapsto Base=12-6=6[/tex]

Now

[tex]\\ \sf\longmapsto Area=\dfrac{1}{2}bh[/tex]

[tex]\\ \sf\longmapsto \dfrac{1}{2}6h=123[/tex]

[tex]\\ \sf\longmapsto 3h=123[/tex]

[tex]\\ \sf\longmapsto h=\dfrac{123}{3}[/tex]

[tex]\\ \sf\longmapsto h=41[/tex]

Answer:

I only know the first one.

The surface area of the prism is 900 cm2

Step-by-step explanation:

To solve the surface area, we need to find the area of the SURFACE not the inside of the cube. Lets do the rectangles first.

28 x 13 = 364

28 x 5 = 140

28 x 12 = 336

   1 1

   336

+  140

   364

-------------

  8 4 0

Now lets do the triangles.

Remember! To find the area of a triangle, you have to do Base x Height x 1/2 because it's half a rectangle.

(The triangles have the same area)

12 x 5 x 1/2 = 30

12 x 5 x 1/2 = 30

  30

+ 30

--------

 60

The last step is to add the areas of the triangles and the rectangles.

   1

   840

+    60

------------

   900 cm2

The answer is 900cm2

This Is not copy pasted, I actually put in all this effort.

Hope this helps :) And have a wonderful day! :D

y=2(.2)

y=.4

there is your answer

Answer:

$3792.69

Step-by-step explanation:

First, we would find the area,

Area = width x length

Area = 9 x 11

Area = 99[tex]m^{2}[/tex]

Since each square meter costs $38.31, we would multiply the cost with the area,

Total Cost = 99 x 38.31

Total Cost = $3792.69

(Anyone can correct me if I'm wrong)

Answer: Domain is [3,∞), The range is All real numbers.

Step-by-step explanation:

Answer:

To find the absolute value of an negative number, just take away the negative sign

The absolute value of a number can NEVER be negative

Step-by-step explanation:

For example, to find the absolute value of -22, it would be 22, since it is 22 points away from zero. To find the absolute value of -99.9, it would be 99.9.

A negative number is NOT always the absolute value of a number.

For example, the absolute value of 34 is, 34. If you plot it on a number line, it is 34 points away from zero, therefore proving a negative number is NOT always the absolute value of a number.

The absolute value of a number can NEVER be negative.

Answer:

The absolute value of a number is always POSITIVE! To find the absolute value, all you need to do is take away the negative sign!

Have a great day!

Answer: p ≤ 5

Step-by-step explanation: The inequality is: p ≤ 5

Answer:

15 cm

Step-by-step explanation:

You need to remember 2 theorems about a rhombus.

1.  The diagonals of a rhombus bisect each other

2.  The diagonals of a rhombus are perpendicular to each other

In other words, the diagonals of a rhombus are perpendicular bisectors.

BE = 9 and AE = 12

ΔAEB is a right triangle.  So, the Pythagorean theorem says

[tex]9^{2} + 12^{2} = AB^{2}[/tex]

[tex]AB^{2}[/tex] = 81 + 144

       = 225

AB = [tex]\sqrt{225} = 15[/tex] cm

Answer:

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)

Answer:

1.518 radians is the answer.

Step-by-step explanation:

Degree to radian conversion = 1° × [tex]\frac{\pi }{180}[/tex]

87° × [tex]\frac{\pi }{180}[/tex]

1.518 radians

Answer:

angle C = angle E. that my answer

Answer:

y = -3/2x + 13

Step-by-step explanation:

(6,4) and (2,10)

Slope:

m=(y2-y1)/(x2-x1)

m=(10-4)/(2-6)

m=6/(-4)

m =  -3/2

Point-slope intercept:

y - y1 = m(x - x1)

y - 4 = -3/2(x - 6)

y - 4 = -3/2x + 9

y = -3/2x + 13

Answer:

10s

Step-by-step explanation:

The product of s and 10

In mathematic, when the word "product" is used, it means multiplication.

10 × s ---> 10s *Both of them are the same.*

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:

The product of s and 10 = 10s

Step-by-step explanation:

The term “product” determines a multipaction problem.

The variable S is unknown within the value

so with a numerical and a algebraic number, the number comes together

Answer:

I think there is an error in the question, I assume it reads:

4x+2y=20

x+3y=50

If not, please make appropriate corrections to the question.

Answer: x=-4, y=18

Step-by-step explanation:

4x+2y=20

Simplify, divide by two,

2x+y=10.....................(1)

x+3y=50....................(2)

Multiply (2) by 2

2x+6y=100 ....................(2a)

Subtract (1) from (2a)

2x+6y - (2x+y) = 100 - 10

5y = 90

y=18..............................(3)

Substitute (3) into (1)

2x+(18)=10

2x = 10-18 =-8

x=-4  ............................(4)

Substitute (3) and (4) into (1) for verification

2x+y = 2(-4)+18 = 18-10 = 10   checks.

Substitute (3) and (4) into (2) for verification

x+3y=-4+3(18) = -4+54 = 50  checks.

Have a nice day!

Answer:

72.37%

Step-by-step explanation:

Calculation for what The sensitivity of the physical examination was

Using this formula

Sensitivity=Positive physical examination cases/Physical examination screening for breast cancer

Let plug in the formula

Sensitivity=5,500 cases / 7600 women

Sensitivity=0.7237*100

Sensitivity=72.37%

Therefore The sensitivity of the physical examination was 72.37%

Answer:

72.37% is the answer for this
