Answer:

Number 3 is correct.

129.19m

Step-by-step explanation:

You might be wondering how did I got 32⁰, well, that's because they are alternate angles.

Now, we're trying to find the opposite side of the triangle.

Using the laws,

we got cos32⁰=x/243.8

243.8cos32⁰=x

Answer:

The -1 came from factoring.

The equation is multiplied by 8 because 8 could be pulled from 16x-8.

16 can be divided by 8 2 times and 8 can only divided by 8 once.

so factoring it makes the equation 8(2x-1)

Answer:

8. Rotating the line 90° around any point.

Step-by-step explanation:

Perpendicular lines intersect each other at a right angle. Therefore, the transformation should create an image that intersects the preimage at an angle of 90∘. Since a rotation changes the angle between the preimage and the image, it can create perpendicular lines.

Answer:

D) 18 bags of chips and 6 jars of salsa

Step-by-step explanation:

Given :  The networking organization you joined is throwing a party. You are in charge of buying the chips, which cost $2.50 per bag and salsa, which costs $4 per jar. The chips & salsa budget you are given totals $60.

Inequality: [tex]2.5x+4y[/tex] ≤ [tex]60[/tex]

Solution :

x represents chips

y represents salsa

Option a: 10 bags of chips and 2 jars of salsa

so, x = 10 and y =2

Putting values in inequality

[tex]2.5(10)+4(2)[/tex] ≤[tex]60[/tex]

[tex]25+8[/tex] ≤[tex]60[/tex]

[tex]33[/tex]≤[tex]60[/tex]

Hence it is correct.

Option c : 14 bags of chips and 5 jars of salsa

so, x = 14 and y =5

Putting values in inequality

[tex]2.5(10)+4(2)[/tex]≤[tex]60[/tex]

[tex]50+8[/tex]≤[tex]60[/tex]

[tex]58[/tex]≤[tex]60[/tex]

Hence it is correct.

Option c : 14 bags of chips and 5 jars of salsa

so, x = 14 and y =5

Putting values in inequality

[tex]2.5(14)+4(5)[/tex]≤[tex]60[/tex]

[tex]35+20[/tex]≤[tex]60[/tex]

[tex]55[/tex]≤[tex]60[/tex]

Hence it is correct.

Option d :18 bags of chips and 6 jars of salsa

so, x = 18 and y =6

Putting values in inequality

[tex]2.5(18)+4(6)[/tex]≤[tex]60[/tex]

[tex]45+24[/tex]≤[tex]60[/tex]

[tex]69\geq 60[/tex]

Hence it is not correct since it violates the inequality

Answer:

1/3 = 2 2/3 eighths.

Step-by-step explanation:

There are 2(2/3) eights in 1/3.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Eighths = 1/8

Now,

(1/8)x = 1/3

Solve for x.

x = 1/3 x 8/1

x = 8/3

x = 2(2/3)

Thus,

There are 2(2/3) eights in 1/3.

Answer:

  a. $850

  b. 7 weeks

  c. f(x) = 125x +475

  d. see attached (3, 850), (7, 1350)

  e. 53 weeks

Step-by-step explanation:

After 3 weeks, $125×3 = $375 will have been added to the $475 already in the account. The balance will be ...

  $375 +475 = $850

__

The student will have to add $1350 -475 = $875 to her account to reach $1350. At a rate of $125 per week, that will take ...

  $875/($125/week) = 7 weeks

__

The initial value is $475, and the rate of change is $125 per week, so the equation can be written ...

  f(x) = 475 +125x . . . . . . . balance after x weeks

__

See the attached graph with the required points marked. (3, 850), (7, 1350)

__

It will take more than 53 weeks for the student to reach her goal. (After 52 weeks, the account will have $6975, so will be $25 short of the goal.)

Answer:

Step-by-step explanation:

Answer: 2

Step-by-step explanation:

Malcom Davis earnings is an illustration of equations and proportions.

Let the profit be P, and the gross income be G.

So, we have:

[tex]\mathbf{P= G - 100000}[/tex]

(a) The equations

For plan A, we have:

[tex]\mathbf{A = \frac{1}{90}G}[/tex] ----1/90 of the company's gross income

For plan B, we have:

[tex]\mathbf{B = \frac{1}{60}P}[/tex]  ----1/90 of the company's profit

When both are the same, we have:

[tex]\mathbf{A= B}[/tex]

This gives

[tex]\mathbf{\frac{1}{90}G= \frac{1}{60}P}[/tex]

Substitute [tex]\mathbf{P= G - 100000}[/tex]

[tex]\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}[/tex]

Hence, the equation is: [tex]\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}[/tex]

(b) Solve the equation in (a), and intepret

[tex]\mathbf{\frac{1}{90}G= \frac{1}{60}(G- 100000)}[/tex]

Cross multiply

[tex]\mathbf{60G = 90G - 9000 000}[/tex]

Collect like terms

[tex]\mathbf{90G - 60G = 9000 000}[/tex]

[tex]\mathbf{30G = 9000 000}[/tex]

Divide both sides by 30

[tex]\mathbf{G = 3000 00}[/tex]

The gross income must be $300000, for Dave to earn the same amount with either plan.

(c) His earnings based on (c)

We have:

[tex]\mathbf{A = \frac{1}{90}G}[/tex]

Substitute [tex]\mathbf{G = 3000 00}[/tex]

[tex]\mathbf{A = \frac{1}{90} \times 300000}[/tex]

[tex]\mathbf{A = 3333.33}[/tex]

His earning is $3333.33 when the plans are the same

(d) If the gross income in less than (b)

If the gross income is less than $300,000, then plan A would better for Malcom Davis, because his earnings in plan A would be greater than plan B
