Help please I don’t know how to do this!!

Answer 1

The answer to this is / 7c -70

Answer 2

7c-70 is the Answer

first you want to do distributive property. since the -10 is on the outside of the parentheses, you multiply it by the numbers that are in the parentheses. After you do this, the equation should look like

50c-40c-70-3c

Then, you want to combine like terms. The 70 does not have a variable so you want to combine the one with exponents which are 50c,-40, and 3c

50-40 is 10. Then you would add the variable: 10c 10c-3c is 7c once all like terms are combined the equation should look like this:

7c-70

A radar operator on a ship discovers a large sunken vessel lying parallel to the ocean surface, 120 m directly below the ship. The length of the vessel is a clue to which wreck has been found. The radar operator measures the angles of depression to the front and back of the sunken vessel to be 55° and 46°. How long, to the nearest tenth of a metre, is the sunken vessel?

Answers

Answer:

The length of the sunken vessel, to the nearest tenth is 200 m

Step-by-step explanation:

The given information are;

The depth of the sunken vessel below the ship = 120 m

The angle of depression to the front of the sunken vessel = 55°

The angle of depression to the back of the sunken vessel = 46°

Therefore, we have;

The length, A, of the from directly below the ship to the front of the sunken vessel given as follows;

Tan(55°) = ((120 m)/A)

A = 120 / Tan(55°) ≈ 84.025 m

The length, B, of the from directly below the ship to the back of the sunken vessel given as follows;

tan(46°) = ((120 m)/B)

B = 120 / tan(46°) ≈ 115.88 m

The length, L, of the sunken vessel = A + B

L = A + B = 120 / Tan(55°) + 120 / tan(46°) ≈ 84.025 m + 115.88 m ≈ 199.91 m

∴ The length, L, of the sunken vessel, to the nearest tenth = 200 m.

What is an equation of the line that passes through the point (5,-8) and is perpendicular to the line 5x- 4y= 16

Answers

4x +5y = -20

for an equation in standard form, you can write the equation for the perpendicular line by swapping the x- and y-coefficients and negating one of them. you need the x-coefficient to be positive, so it is needed to negate that one here. This gives you the equation ...
4x +5y = (some constant)
You find the value of the constant by evaluating the expression at the given point:
4x +5y = 4(5) +5(-8) = -20
The equation is 4x +5y = -20

Answer

y=-4/5x-4

Rebecca wants to bye cupcakes and juice boxes for a party.Cupcakes come in packages of 12, and juice boxes come in packages of 10. She wants an equal number off cupcakes and juice boxes.What is the fewest number of packages of each Rebecca should buy?

Answers

2

2 is the highest number that both 10 and 12 are divisible by

hope this helps

Answer:

Rebecca would need to buy 5 packages of cupcakes and 6 packages of juice boxes

Step-by-step explanation:

To find the equal number of cupcakes and juice boxes, you have to find the LCM(least common multiple)

12×1 = 12 ≠ 10 ×1 = 12

12×2 = 24 ≠ 10×2 = 20

12×3 = 36 ≠ 10×3 = 30

12×4 = 48 ≠ 10×4 = 40

12× 5 = 60 ≠ 10×5 = 50

12 × 5 = 60 = 10×6 = 60

Therefore, Rebecca would need to buy 5 packages of cupcakes and 6 packages of juice boxes

Hope this made sense!!!

Inequality: [tex]5x+6\geq 31[/tex]

Solution: [tex]x\geq 5[/tex]

Step-by-step explanation:

"Six more" is asking you to add 6, so add 6 to 5 times x.

"At least" means equal or greater than, so the inequality has to be equal or greater than 31.

To solve for x, subtract 6 from both sides of the inequality to get [tex]5x\geq 25[/tex]

Then divide both sides by 5 to get [tex]x\geq 5[/tex]

2 Answers: Choice B, Choice EThe range is the set of output values.5 is included in the domain of this relation.

==========================================

Explanation:

Choice A is false because the domain consists of the x values, not the y values. The domain is the set of allowed inputs.Choice B is true because the range is the set of possible output y values.Choice C is false because the input x = 5 leads to multiple outputs (y = -3 and y = 2 at the same time). Plotting all the points on the same xy grid shows the relation fails the vertical line test.Choice D is false because y = 0 is not in any of the points. Choice E is true since x = 5 is part of (5,-3) and (5,2)

Question
Enter a recursive rule and an explicit rule for the arithmetic sequence. Then, find the 20th term of the
sequence
55, 65, 75, 85,-
The recursive rule is f(1) =
f(n)=f(?
+
The explicit rule is f(n) =
+
?
f(20) =

Answers

Answer:

The recursive rule is [tex]f(1)[/tex] = first term; [tex]f_({n})[/tex] = [tex]f_({n-1})[/tex] + d

f(1) = 55; [tex]f_{20}[/tex] = [tex]f_{19}[/tex] + 10

The explicit rule is f(n) = f(1) + (n - 1)d

f(20) = 245

Step-by-step explanation:

The recursive rule of the arithmetic sequence is

[tex]a_{1}[/tex] = first term; [tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + d

Where:

[tex]a_{1}[/tex] is the first term in the sequence [tex]a_{n}[/tex] is the nth term in the sequence [tex]a_{n-1}[/tex] is the term before the nth term n is term number d is the common difference.

The explicit rule of the arithmetic sequence is

[tex]a_{n}=a_{1}+(n-1)d[/tex]

where:

[tex]a_{1}[/tex] is the first term in the sequence [tex]a_{n}[/tex] is the nth term in the sequence n is term number d is the common difference

∵ The first 4 terms of the sequence are 55, 65, 75, 85

∴ [tex]a_{1}[/tex] = 55

∵ d = 65 - 55

∴ d = 10

∵ We need to find the 20th term

∴ n = 20

∵ The recursive rule is [tex]f(1)[/tex] = first term; [tex]f_({n})[/tex] = [tex]f_({n-1})[/tex] + d

→ Substitute the values of [tex]a_{1}[/tex], n, and d in recursive rule

∴ f(1) = 55; [tex]f_{20}[/tex] = [tex]f_{19}[/tex] + 10

∵ The explicit rule is f(n) = f(1) + (n - 1)d

→ Substitute the values of n and d to find it

∴ f(20) = 55 + 19(10) = 245

∴ f(20) = 245
