Answer:

The complement of 46° = 44°

The supplement of 82° = 98°

Step-by-step explanation:

Complement means 90° - the angle (46°).

So, 90° - 46° = 44°

Supplement means 180° - the angle (82°)

So, 180° - 82° = 98°

The complement of 46° = 44°

The supplement of 82° = 98°

Complementary angles are two angles that have a sum of 90°.

Supplementary angles are two angles that have a sum of 180°.

According to the question

a. An angle measures 46°.

The measure of its complement :

The meaning of complementary angle is two angles that add up to 90 degrees.

Complementary angles = sum of two angles = 90 degrees.

x° = y° + z°

90° =  y° + z°

Given y° = 46°

z° = 90° -  y°

z° = 90° -  46°

z° = 44°

The measure of its complement is 44°.

b. An angle measures 82°.

The meaning of supplementary angle is two angles that add up to 180 degrees.

Supplementary angles = sum of two angles = 180 degrees.

a° = b° + c°

180° =  b° + c°

Given  b° =  82°

c° = 180° -  b°

z° = 180° -  82°

z° = 98°

The measure of its supplement is 98°.

Answer:

there you go

Step-by-step explanation:

Answer:

See below for answers

Step-by-step explanation:

y=5(2)ˣ

y=5(2)⁻²=5(1/2²)=5(1/4)=5/4

y=5(2)⁻¹=5(1/2¹)=5(1/2)=5/2

y=5(2)⁰=5(1)=5

y=5(2)¹=5(2)=10

y=5(2)²=5(4)=20

Write the system as an augmented matrix:

[tex]\left[\begin{array}{cc|c}1&5&22\\4&-7&7\end{array}\right][/tex]

Add -4 (row 1) to row 2 :

[tex]\left[\begin{array}{cc|c}1&5&22\\0&-27&-81\end{array}\right][/tex]

Multiply row 2 by -1/27 :

[tex]\left[\begin{array}{cc|c}1&5&22\\0&1&3\end{array}\right][/tex]

Add -5 (row 2) to row 1 :

[tex]\left[\begin{array}{cc|c}1&0&7\\0&1&3\end{array}\right][/tex]

Then x = 7 and y = 3.

Answer: x=1/2=0.5

Step-by-step explanation:

Given

3(2x) - 4(3x) + 3= 0

Expand parenthesis

6x - 12x + 3 = 0

Combine like terms

-6x + 3 = 0

Subtract 3 on both sides

-6x + 3 - 3 = 0 - 3

-6x = -3

Divide -6 on both sides

-6x / -6 = -3 / -6

x = 1/2 = 0.5

Hope this helps!! :)

Answer:

l = (3x+5)

Step-by-step explanation:

Given that,

The area of a room, [tex]A=3x^2-x-10[/tex]

The width of the room, [tex]b=(x-2)[/tex]

We need to find the length of the room.

The area of the room is given by :

A = lb

[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^2-x-10}{x-2}\\\\l=\dfrac{(x-2)(3x+5)}{x-2}\\\\l=(3x+5)[/tex]

So, the length of the room is equal to (3x+5).

Answer:

[tex]d = 787.81cm^3[/tex]

Step-by-step explanation:

Given

See attachment for the containers

Required

The difference in the amount of snow cone they hold

The amount they hold is determined by calculating the volume of the containers.

The traditional snow cone has the following dimension

Shape: Cone

[tex]r=4cm[/tex] --- radius

[tex]h = 13cm[/tex] --- height

The volume is calculated as:

[tex]Volume = \frac{1}{3} \pi r^2h[/tex]

So, we have:

[tex]V_1 = \frac{1}{3} \pi * 4^2 * 13[/tex]

[tex]V_1 = \frac{208}{3} \pi[/tex]

The snow cone in a cup has the following dimension

Shape: Cylinder

[tex]r=8cm[/tex] --- radius

[tex]h = 5cm[/tex] --- height

The volume is calculated as:

[tex]Volume = \pi r^2h[/tex]

So, we have:

[tex]V_2 = \pi *8^2 * 5[/tex]

[tex]V_2 = \pi *320[/tex]

[tex]V_2 = 320\pi[/tex]

The difference (d) in the amount they hold is:

[tex]d = V_2 - V_1[/tex]

[tex]d = 320\pi - \frac{208\pi}{3}[/tex]

Take LCM

[tex]d = \frac{3*320\pi -208\pi}{3}[/tex]

[tex]d = \frac{960\pi -208\pi}{3}[/tex]

[tex]d = \frac{752\pi}{3}[/tex]

Take [tex]\pi = 22/7[/tex]

[tex]d = \frac{752}{3} * \frac{22}{7}[/tex]

[tex]d = \frac{752 * 22}{3*7}[/tex]

[tex]d = \frac{16544}{21}[/tex]

[tex]d = 787.81cm^3[/tex]

Answer:

Jamal predicts that 243 people will visit his site on the fifth day.

Step-by-step explanation:

Since Jamal launched a website for his custom shoe store, and on the first day, 3 visitors registered on the website, while on the third day, 27 visitors registered on the website, if Jamal uses an exponential function to model the data from the first and third days, to determine how many visitors will predict to register on the fifth day, the following calculation must be performed:

Day 1 = 3

Day 2 = 3 ^ 2 = 9

Day 3 = 3 ^ 3 = 27

Day 4 = 3 ^ 4 = 81

Day 5 = 3 ^ 5 = 243

Therefore, Jamal predicts that 243 people will visit his site on the fifth day.

I did the quiz and it is B

Step-by-step explanation:

Answer:

40 m

Step-by-step explanation:

The length of another side

= 99÷11

= 9 m

The perimeter of the field

= 9×2 + 11×2

= 40 m

Answer:

40 m

Step-by-step explanation:

Hi there!

What we know:

1) Find the length of the other side

Plug all the given information into the area formula for a rectangle:

[tex]A=lw[/tex] where A is the area, l is the length and w is the width

[tex]99=11w[/tex]

Divide both sides by 11 to isolate w

[tex]\frac{99}{11} = \frac{11w}{11} \\9=w[/tex]

Therefore, the width of the field is 9 m.

2) Find the perimeter of the field

[tex]P=2(l+w)[/tex] where l is the length and w is the width

Plug in the length (11 m) and the width (9 m)

[tex]P=2(11+9)\\P=2(20)\\P=40[/tex]

Therefore, the perimeter of the field is 40 m.

Answer:

A=250

r= 15%

Step-by-step explanation:

Given data

We have the function

y = 250(.85)^6------------1

The given function is the same as the exponential decrease

function

P=A(b)^t---------------------2

Note

b= 1-r= 1-0.15

b= 0.85

When we compare both 1 and 2 above

A=250

r= 15%

Answer:

BD = 3.2.

CD = 2.4.

Step-by-step explanation:

By Pythagoras:

AB^2 = 3^2 + 4^2 = 25

AB = 5.

Triangles ADC and ACB are similar, so

AC / AB = AD / AC

3 / 5 = AD / 3

AD = 3*3/5

AD =  9/5 = 1.8

So BD = 5 - 1.8

= 3.2.

CD^2 = AC^2 - AD^2 (Pythagoras)

CD^2 = 3^2 - 1.8^2 = 5.76

CD = 2.4.
