Answer 1

Answer:

Step-by-step explanation:

So, lets go over a few things:

First off, all triangles have a total angle of 180 degrees.

Secondly, we know that the first two angles are 57 and 51.

Thirdly, we know that the missing angle is 9x

To solve this, we must add together the known angles, subtract them fro 180, and divide that by 9. This will give us the missing x value.

So, add together the two angles we know:

57+51

108

So we know 108 degrees of our triangle. We must find whats left of the 180.

To do this, subtract 108 from 180:

180-108

So our remaining angle is 72 degrres.

But recall that x isnt the misisng angle, 9x is.

So, to get x on its own, we must divide both the missing angle and 9x by 9:

72=9x

--- ---

9 9

8=1x

So now we know that x equals 8.

I hope this helps! :)

Answer 2

Answer:

X = 8

Step-by-step explanation:

Okay so we know that there are a total of 180 degrees in every triangle. We need to create the equation to define the triangle's angles. 51 + 57 + 9x = 180. Then, we will solve for x.

180 = 51 + 57 + 9x we are going to simplify the equation by solving what we can

180 = 108 + 9x * Now we will isolate x

180 - 108 = 9x * Solve the left side of the equation

72 = 9x * Divide both sides by 9

8 = x

Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes. Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65. How many bags of carrots and how many bags of tomatoes did he buy? Enter your answers in the boxes below. (Use x for carrots and y for tomatoes.)

Answers

Answer:

x= 12

Step-by-step explanation:

The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.

What is equation?

An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, it can be said as of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes.

Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65.

let, he bought x bags of carrots and y bags of tomatoes.

now, we get,

x+y = 11 ....(1)

1.05x + 1.65y = 16.35 ....(2)

solving this, we get,

x= 3

y= 8

Hence, The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.

On the first day it was posted online, a music video got 250 views. The number of views that the video got each day increased by 16% per day. How many total views did the video get over the course of the first 12 days, to the nearest whole number?

Answers

Using an exponential function, it is found that the video got 8,314 total views over the course of the first 12 days.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the growtn rate, as a decimal.

On the first day it was posted online, a music video got 250 views, and the number increased by 16% a day, hence the A(0) = 250, r = 0.16, and the equation is given by:

[tex]A(t) = 250(1.16)^t[/tex]

The total amount over the first 12 days is given by:

[tex]T = \int_{0}^{12} A(t) dt[/tex]

[tex]T = \int_{0}^{12} 250(1.16)^t dt[/tex]

[tex]T = 250\frac{(1.16)^t}{\ln{1.16}}|_{t = 0}^{t = 12}[/tex]

Applying the Fundamental Theorem of Calculus:

[tex]T = 250\frac{(1.16)^{12}}{\ln{1.16}} - 250\frac{(1.16)^0}{\ln{1.16}}[/tex]

T = 8314.

The video got 8,314 total views over the course of the first 12 days.

Find the angle made by the x axis and the terminal side resulting from connecting the origin to (5,7), rounded to the nearest integer

Answers

Answer:

55°

Step-by-step explanation:

To solve this, follow these steps:

i. Make a sketch of the problem.

The sketch has been attached to this response.

ii. Label the sketch properly

As shown in the sketch, θ is the angle between the x-axis and the terminal side resulting from connecting the origin to (5,7).

iii. Solve using the tangent trigonometric ratio

With the proper sketch and labelling, a right triangle is formed with the adjacent and opposite sides to the angle being 5 units and 7 units respectively.

Using the tangent formula,

tan θ = opposite / adjacent

tan θ = 7 / 5

θ = tan⁻¹ (7/5)

θ = tan⁻¹ (1.4)

θ = 54.46

θ = 55° to the nearest integer.

Therefore, the angle made by the x axis and the terminal side resulting from connecting the origin to (5,7), rounded to the nearest integer is 55°
