Find the length of AB

Answer:

15/4 in or 3.75 in

Step-by-step explanation:

Find your equations:

L = 4w + 9 in

A = L*w = 90 in^2

Substitute L:

L*w = 90 in^2  <--  L = 4w + 9

(4w + 9in)w = 90 in^2  

4w^2 in^2 + 9w in = 90in^2

Solve Simultaneously:

w = -6 in, 15/4 in

Width is positive so it is 15/4 in or 3.75 in.

Double check:

(4w + 9in)w = 90 in^2  

(4*3.75in + 9in)(3.75in) = 90 in^2

........Option C ) n × 2 = t

Step-by-step explanation:

Hey there!

In (a) part let us take the value of n as 1 first.

n + 2

=> 1+2

= 3

But it doesn't get matched with t.

So, (a) option cancelled.

In (b) part, let us take the value of n as 1.

n - 2

=> 1 - 2

= -1

But this also didn't match with t.

Option (b) cancelled.

In (c) part, let us take the value of n as 1.

n × 2

=> 1 × 2

= 2

Matched! Let us check further. Taking value of n as 2,

=> 2 × 2

= 4

Matched again! So, (c) part is the correct answer.

Let us take the value of n as 1. (For both option (d) and (e))

n + 3

=> 1 + 3

= 4 (wrong)

n + 4

=> 1 + 4

= 5 (wrong)

So, (c) part is the right answer.

Hope it helps :)

Answer:

216 in2

Step-by-step explanation:

the area of the rectangle is

20(12)=240

area of the triangle is

4(6)= 24

so now we subtract, 240-24= 216 in2

Answer:

228

Step-by-step explanation:

12x8=96 (times 2= 192)

20-(8+8 or 16)=4

4x12=48

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

6x4=24 (divided by 2 because it is a triangle=12)

48-12=36

A triangular prism and its dimensions are shown in the diagram. What is the lateral surface area of this triangular prism in square centimeters? F 192 cm2 G 128 cm2 H 152 cm2 J 144 cm

Answer:

G

The lateral surface area of the triangular prism is 128 square centimeters. The correct answer would be an option (G) 128 cm².

A triangular prism is a three-sided prism consisting of a triangular base, a translated duplicate, and three faces connecting similar sides.

As per the question, we have dimension are:

side legth of base  = 6 cm, 5 cm, and 5 cm

height = 8 cm

Lateral surface area = (a+b+c)h

Substitute the values and we get

Lateral surface area = (6+5+5)8

Lateral surface area = 16 × 8

Lateral surface area = 128 cm².

Hence, the lateral surface area of the triangular prism is 128 square centimeters.

The missing figure has been attached below.

Answer:

373248 cm³ of wax

Step-by-step explanation:

If the crayon is 90 millimeters long, how many cubic centimeters of wax is used to make a box of 8 crayons?

1 crayon = 90mm

8 crayons = x

Cross Multiply

x = 8 × 90mm

x = 720mm

Converting to cubic mm

= (720mm)³ = 373248000mm³

Converting to cubic centimeter

1 mm³ = 0.001 cm³

373248000 mm³ = x

Cross Multiply

373248000 × 0.001 cm³

= 373248 cm³ of wax

Answer:

Her total loss was £25

Step-by-step explanation:

Here, we want to get the value of total loss

What we have to do here is to subtract the amount made from the running cost

From the question, we have the amount made as;

£1.40 * 50 = £70

So we have the loss as,

70-95 = -£25

Answer:

87

Step-by-step explanation:

first find x

all triangles = 180°

180=32+2x+x+15

combine like terms

180=47+3x

180-47=133

133=3x

133/3=44.334 or 44 1/3

2(44.334)= 88.66 ooor 87 if you round it

Answer:

2π + 24 m² = 30.3 m²(3 s.f.)

Area of rectangle: l x w

6 x 4 = 24 m²

Area of semicircle: πr²/2

r = 4/2 = 2

π x 2² / 2

4π / 2

2π

Total area: 2π + 24 m² = 30.3 (3 s.f.)

Answer:

41

Step-by-step explanation:

In order to find the measure of angle C we must find the value of x

Remember the measures of the angles in a triangle add up to equal 180

that being said we use this equation to solve for x

180 = (sum of angles) 63 + 2x + 8 + x + 7

now we solve

step 1 combine like terms

63 + 7 + 8 = 78

2x + x = 3x

now we have 180 = 78 + 3x

step 2 subtract 78 from each side

180 - 78 = 102

78 - 78 cancels out

now we have 102 = 3x

step 3 divide each side by 3x

102/3=34

3x/3=x

we're left with x = 34

Now to find the measure of angle C

We plug in the value of x in the expression (x + 7)

so c = 34 + 7

34 + 7 =  41

therefore your answer is 41

Answer:

x = -4 + 3√2 and x = -4 - 3√2

Step-by-step explanation:

Complete the square of x^2+8x-2=0:

Between 8x and -2, write in 4^2 - 4^2, so that we now have:

x^2 + 8x + 16 - 16 - 2 = 0, or by writing x^2 + 8x + 16 as the square of a binomial, (x + 4)^2 = 18

Taking the square root of both sides, we get:

x + 4 = √18 = ±√9√2, or ±3√2

Then x = -4 + 3√2 and x = -4 - 3√2

Answer:C) 9/12

Step-by-step explanation:

In the given diagram, the value of x is 15

The Pythagorean theorem states that, in a right triangle, the square of the longest side (hypotenuse) equals sum of squares of the other two sides

From the question, we are to determine the value of x.

x is the radius of the circle

Recall: Radius is any line that runs from the center to any part of the circumference

Consider the right triangle formed, x is the hypotenuse

By the Pythagorean theorem,

x² = 9² + 12²

x² = 81 + 144

x² = 225

x = √225

x = 15

Hence, the value of x is 15.

The list that represents the values of x for which the function has a discontinuity is 0 and 1

The function is given as:

[tex]f(x)=\dfrac{1}{x(x-1)}[/tex]

Start by setting the denominator to 0

x(x -1) = 0

Split the equation

x = 0 and x -1 = 0

Solve for x

x = 0 and x = 1

Hence, the list that represents the values of x for which the function has a discontinuity is 0 and 1.
