Name two pairs of congruent angles

Answers

Answer:

∠JKL and ∠GKH

Step-by-step explanation:

1. Because these intersecting lines are forming opposite pairs of angles, there  are some vertical angles. Vertical angles are congruent.

2. As you can see, ∠JKL is 55°. The angle that forms the pair of opposite angles with ∠JKL is ∠GKH.

3. As aforementioned, because these two angles are vertical angles, they're congruent.

Therefore, two pairs of congruent angles are ∠JKL and ∠GKH.

8.5x-2(2x+8) Pls give steps and I need it in expanded from

Answers

Answer:

[tex]\frac{9x}{2}[/tex] - 16

Step-by-step explanation:

8.5x - 2(2x + 8)

Use the distributive property to multiply −2 by 2x+8.

8.5x - 4x - 16

Combine 8.5x and −4x to get 4.5x.

4.5x - 16

= [tex]\frac{9x}{2}[/tex] - 16

You must distribute first so -2•2x=-4xand -2•8=-16
So expanded form is 8.5x•(-2•2x)+(-2•8)

С x-4 = 0 OR x-4 = 0
D x = 4 or x = 5 ​

Answers

Answer:

(B) (x - 4)(x – 5) = 0

Step-by-step explanation:

He made a mistake at step 2.

(x - 4)(x - 5) = 0 is incorrect as

it is same as x² - 9x + 20 = 0

It should be:

(x - 10)(x - 2) = 0 with the end result x = 10 or x = 2

Let's solve

[tex]\\ \sf\longmapsto x^2-12x=-20[/tex]

[tex]\\ \sf\longmapsto x^2-12x+20=0[/tex]

[tex]\\ \sf\longmapsto x^2-10x-2x+20=0[/tex]

[tex]\\ \sf\longmapsto x(x-10)-2(x-20)=0[/tex]

[tex]\\ \sf\longmapsto (x-10)(x-2)=0[/tex]

In a laboratory experiment, the population of bacteria in a petri dish started off at
2600 and is growing exponentially at 13% per day. Write a function to represent the
population of bacteria after t days, where the hourly rate of change can be found
from a constant in the function. Round all coefficients in the function to four decimal
places. Also, determine the percentage rate of change per hour, to the nearest
hundredth of a percent.

Answers

Answer:

See below

Step-by-step explanation:

Daily growth rate is 13% with initial values of 2600 bacteria.

The equation is:

[tex]f(t) = 2600*( 1 + 0.13)^t=2600*1.13^t[/tex]

Find the hourly rate x considering 1 day = 24 hours:

[tex]2600*1.13^{t/24}=2600*x^t[/tex][tex]ln 1.13^{t/24}=ln x^t[/tex][tex]ln1.13^{1/24}=lnx[/tex][tex]x=1.13^{1/24} =1.0051[/tex]

Percentage rate of change per hour is:

The perimeter of a rectangular window is 264 cm. If the width of the window is 56 cm what is its length. *

Answers

Answer:

76 cm.

Step-by-step explanation:

56 times 2 is 112

264-112=152, divide by 2

152/2=76

Answer:

76 cm

Step-by-step explanation:

Perimeter is the sum of all sides of a rectangle. It can also be thought of as 2 times the width plus 2 times the width.

[tex]P=2L+2w[/tex]

Rearranging to solve for length:

[tex]2L=P-2w[/tex]

[tex]L=\frac{P-2w}{2}=\frac{264-2(56)}{2}=\frac{152}{2}=76[/tex]

The length is 76 cm.

Find the missing dimension of the prism. Volume = 532 in. 3 19 in​

Subtract them but turn 532 into a decimal

The required width of the rectangular prism is 16in.

What is a rectangular prism?

A rectangular prism is a three dimensional shape , that has six faces. The shape of a rectangular prism is just a cuboid shape.

Use the formula of volume of a cuboid since a rectangular prism is in the shape of a cuboid. The volume of a cuboid is V= length×breadth×height.

Given that, The volume of prism V=[tex]532 in^{3}[/tex]

The length of prism , L= 19in.

The height of prism [tex]H=1\frac{3}{4}=\frac{7}{4}[/tex].

The width, W=?

The rectangular prism has volume V=Length×Height×Width.

Therefore,  532=19×(7/4)×W

So,  532×4=19×7×W

Thus,  (532×4)/(19×7)=W

Therefore,  W=16in.

Thus, the width of the rectangular prism is 16in.

Nine less than four times a number is the same as nineteen

Answers

Answer:

x= 7, the number is 7

Step-by-step explanation:

4x-9= 19

Add 9 to both sides

4x=28

Divide each side by 4

x=7

Answer:

4x - 9 = 19

Step-by-step explanation:

We can represent 4 times any numbers as 4x.

Then they want 9 less than 4x. This means that they want 4x but 9 units shorter. So to make 4x 9 units shorter, you would take away 9 from 4x which is represented as 4x - 9. A common mistake is writing this as 9 - 4x.

They also want 4x - 9 to be the same, or equal to, 19. So to equate both expression, you would add the equals sign between both expressions.
