Answer 1
the answer is C)-1

for this problem i did this:
4x+3y=-3
4(0)+3y=-3
3y=-3
y=-1

a simple way to find the y intercept is to make x equal 0 and then continue to solve the equation...if you were to solve for the y intercept you would make y equal 0 and then continue to solve the equation
(i hope that made sense)

. A flagpole is standing in front of City Hall. Percy, who is standing near the flagpole is 5' tall and casts a shadow 3' long. If the flagpole casts a shadow 36' long, how tall is the flagpole

Answers

Answer:

The flagpole is 60'(60 inches) tall

Step-by-step explanation:

A flagpole is standing in front of City Hall. Percy, who is standing near the flagpole is 5' tall and casts a shadow 3' long. If the flagpole casts a shadow 36' long, how tall is the flagpole

The formula is given as:

Height of percy/ Shadow of percy = Height of flagpole/Shadow of flagpole

Height of percy = 5 inches

Shadow of percy = 3 inches

Height of flagpole = ??

Shadow of flagpole =36 inches

= 5/3 = x/36

Cross Multiply

3 × x = 36 × 5

3x = 36 × 5

x = 36 × 5/3

x = 60 inches

Therefore, the flagpole is 60'(60 inches) tall.

PLEASE HELP ME FAST!!! Monica's bicycle wheel has a radius of 16 inches. Kevin's tricycle wheel has a radius of 8 inches. How many times larger is the circumference of Monica's wheel that the circumference of Kevin's tricycle wheel? Show your work

Answers

Answer:

50.2 inches

Step-by-step explanation:

The wheel of a tricycle is circular in shape.

The circumference of a circle = 2πr

For Monice

Monica's bicycle wheel has a radius of 16 inches.

The circumference of her bicycle wheel = 2 × π × 16

= 100.53096491 inches

Approximately = 100.5 inches

For Kevin

Kevin's tricycle wheel has a radius of 8 inches.

The circumference of his wheel =

2 × π × 8

= 50.265482457 inches

Approximately = 50.3 inches

How many times larger is the circumference of Monica's wheel that the circumference of Kevin's tricycle wheel?

This is calculated as:

Circumference of Monica's wheel - Circumference of Kevin's wheel

= 100.5 inches - 50.3 inches

= 50.2 inches

Hence: Monica's wheel is 50.2 inches larger than Kevin's wheel

Answer: All I know is I got a 1/2 points on my open ended question. Monica’s bicycle wheel is 2 times larger than Kevin’s.

Step-by-step explanation: I think you add or multiply or divide. I gotta figure it out myself.

Your new job is at the custom t shop, where t-shirts are printed to order. For each order, custom t shop charges $8.00 per shirts plus a one time set up fee for $15.00

Answers

Answer:

Price = 15+8t

Step-by-step explanation:

Your new job is at the custom t shop, where t-shirts are printed to order.

For each order, custom t shop charges $8.00 per shirts plus a one time set up fee for $15.00.

Here, $15 remain fix and $8 increases with number of shirts.

Price = 15+8t

Hence, the price of the t-shirts is "15+8t".

Then times the answer u get by 3

Answer:

A) How much material does he need to cover the one rectangular side of the tent with the rip? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.  

Answer: If David’s dad wanted to cover the rectangular side of the tent, he would need to multiply the sides together. Using the formula A = l x w, I can solve for 6 and 9. 9 x 6 = 54, so 54 = 6 x 9.  

B) If David’s dad wanted to re-cover the whole tent including the bottom, how much material would he need?  Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.

Answer: If he wanted to re-cover the whole tent, he would need the product of the rectangular side, the triangular side, and the bottom side. Using A = l x w, I can solve for each side of the tent, For the rectangular side you multiply six by nine, then multiply two by the product. 6 x 9 = 54 x 2 = 108. For the triangular side, I need to multiply six times seven, 6 x 7 = 42. For the bottom, I need to multiply seven times nine, 7 x 9 = 63. Finally, I need to add them all up. 108 + 42 + 63 = 213 ft².                    

 

C) What is the volume of the tent?  Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning. (You need to find the area of one of the triangular bases, and then you can take that measurement and multiply it with the height of the entire prism.) V=Bh, where B = area of one of the triangular bases

Answer: I need to find the volume of the tent, so I need to find the formula which is V = B x h. The base is 63, because I needed to find the area of one of the triangular bases, so I multiplied 7 x 9 = 63. The height is 6, so I need to multiply 63 x 6. When I multiply 63 x 6, I get the product of 378, so the volume of the tent is 378 ft³.

Answers

Answer:

1836 bacteria

Step-by-step explanation:

Now the data is a progression; 38,000, 33,820, 30,100 .........

We can find out what type of progression it is, in this case, we can see that it is a geometric progression because;

r= 33,820/38,000 = 30,100/33,820 = 0.89

So, for a geometric progression;

Un = ar^n-1

Where;

a = 38,000

r = 0.89

n = 27 days

Un = ???

Un = 38,000 * (0.89)^27 - 1

Un = 1836 bacteria

What is the measure, in radians, of central angle POQ? StartFraction 2 pi Over 3 EndFraction radians StartFraction 3 pi Over 4 EndFraction centimeters StartFraction 4 pi Over 3 EndFraction radians StartFraction 3 pi Over 2 EndFraction radians

Answers

Answer:

The answer is "[tex]\bold{\frac{2 \pi}{3}}[/tex]"

Step-by-step explanation:

Please find the complete question in the attached file.

Using formula:

[tex]\to \bold{\theta = \frac{S}{r}}[/tex]

Where,

[tex]\theta =central \ angle \\\\{S} = arc \ length\\\\{r} = radius \ length[/tex]

[tex]\to \theta = \frac{PQ }{OQ}[/tex]

       [tex]=\frac{6 \pi}{9} \\\\ = \frac{2 \pi}{3}[/tex]

The radian measure of central angle POQ is 3π/4 radians. Option b) is the correct option.

Line segments PO and QO are radii.

We need to find the radian measure of central angle POQ.

How to find the relation between angle subtended by the arc, the radius and the arc length?

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

The superscript 'c' shows angle measured is in radians.

If the radius of the circle is of r units, then:

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

We know that

π radians = 180°

Therefore,

180° = π radians

135° = x

180° × x = 135° × π radians

x = 135° × π radians/180

x = 3π/4 radians

Hence, the radian measure of central angle POQ is 3π/4 radians. Option b) is the correct option.

In the triangle below, with right angle A, suppose that m is Angle B=(5x+7) and m is Angle C=(4x+29) Find the degree measure of each angle in the triangle. A= 90 B=(5x+7) C=(4x+29)

Answers

Given:

Triangle ABC is right angled at A.

[tex]m\angle B=(5x+7)^\circ[/tex]

[tex]m\angle C=(4x+29)^\circ[/tex]

To find:

The degree measure of each angle in the triangle.

Solution:

According to the given information,

[tex]m\angle A=90^\circ[/tex]

[tex]m\angle B=(5x+7)^\circ[/tex]

[tex]m\angle C=(4x+29)^\circ[/tex]

Now,

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]        (Angle sum property)

[tex]90^\circ+(5x+7)^\circ+(4x+29)^\circ=180^\circ[/tex]

[tex](9x+126)^\circ=180^\circ[/tex]

[tex]9x+126=180[/tex]

[tex]9x=180-126[/tex]

[tex]9x=54[/tex]

Divide both sides by 9.

[tex]x=\dfrac{54}{9}[/tex]

[tex]x=6[/tex]

Now,

[tex]m\angle A=90^\circ[/tex]

[tex]m\angle B=(5(6)+7)^\circ[/tex]

[tex]m\angle B=37^\circ[/tex]

[tex]m\angle C=(4(6)+29)^\circ[/tex]

[tex]m\angle C=53^\circ[/tex]

Therefore, the measures of ∠A, ∠B, ∠C are 90°, 37°, 53° respectively.
