Answer 1

Answer:

773 or 278.5 (if it only wants the sides the pic shows)

Step-by-step explanation:

13*5=65

65/2=32.5 (since it is a triangle you by 2)

12*9=108

108/2=54

15*20=300 (it is a square so you leave it)

you do it on the other sides that you can't see in the pic.

Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773

Hope this helps!

In an electric circuit, the current varies inversely as the resistance. The current is 40 amps when the resistance is 12 ohms. Find the current when the resistance is 20 ohms.

Answers

Answer:

24 amps

Step-by-step explanation:

Current = k /resistance

k = current × resistance

= 40 × 12

= 480

If the resistance is 20 ohms then the current can be calculated as follows

Current = 480/20

= 24 amps

Fernando is trying to incorporate more exercise into his busy schedule. He has several short exercise routines he can complete at home. Last week, he worked out for a total of 88 minutes by doing 2 arm routines and 3 abdominal routines. This week, he has completed 4 arm routines and 1 abdominal routine and spent a total of 66 minutes exercising. How long does each routine last?

Answers

Answer: Arm routine = 11 minutes

Abdominal routine = 22 minutes

Step-by-step explanation:

Let the minutes used for an arm routine be represented by x.

Let the minutes used for an abdominal routine be represented by y.

Last week, he worked out for a total of 88 minutes by doing 2 arm routines and 3 abdominal routines. This can be expressed as:

2x + 3y = 88

This week, he has completed 4 arm routines and 1 abdominal routine and spent a total of 66 minutes exercising. This can be expressed as:

4x + y = 66

2x + 3y = 88 ...... i

4x + y = 66 ...... ii

Multiply equation I by 4

Multiply equation ii by 2

8x + 12y = 352 ...... iii

8x + 2y = 132 ...... iv

Subtract iv from iii

10y = 220

y = 220 / 10

y = 22

An abdominal routine last for 22 minutes

From equation I

2x + 3y = 88

2x + 3(22) = 88

2x + 66 = 88

2x = 88 - 66

2x = 22

x = 22/2

x = 11 minutes

An arm routine last for 11 minutes

Find the value of the trigonometric ratio.
9) sin z

Answers

Answer:

SinZ=24/40 = 12/20 = 3/5

C)

The value of the trigonometric ratio Sin Z for the given triangle XYZ will be [tex]\frac{3}{5}[/tex], i.e. option C.

What are trigonometric ratios?

The trigonometric ratios are the ratios of sides of two sides of right angled triangle used in trigonometry. Trigonometric ratios are used to find the value of the acute angles in a right triangle when the sides of the triangle are given.

We have,

A right-angled triangle XYZ with the given values,

Angle Y = 90°

And,

YZ = 32, XY = 24 and XZ = 40,

Now,

Using the trigonometric ratios,

i.e.

[tex]Sin Z=\frac{Perpendicular}{Hypotenuse}[/tex]

i.e.

[tex]Sin Z=\frac{XY}{XZ}[/tex]

So,

[tex]Sin Z=\frac{24}{40}[/tex]

On simplifying,

We get,

[tex]Sin Z=\frac{3}{5}[/tex]

So,

The option C is the correct answer for the given triangle find out using trigonometric ratio,

Hence, we can say that the value of the trigonometric ratio Sin Z for the given triangle XYZ will be [tex]\frac{3}{5}[/tex], i.e. option C.

Answers

The equation would be 1.50x - 14 = P

If lucas sells 19. cups then that means he will earn a total of 29.25$ but since he spent 14$ for the materials itself that concludes to the total being 15.25.This would be a viable solution because he is earning more money then  he is loosing.

A fundraiser is being held to support a local nonprofit organization. Admission costs $10, and each raffle ticket costs $3. There are no other possible costs. If an event-goer pays the admission fee and buys x number of tickets, what type of function should be used to model the total amount spent by the event-goer at the event?

Answers

Answer:

y= 10+ 3x

10 is the admission fee

3x is the cost for each ticket

y is the total

The function for the total cost (y) spent by the event-goer at the event is

y = 3x+10

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Given that, Admission costs $10, and each raffle ticket costs $3. There are no other possible costs.

Let the total cost be y,

Therefore, establishing the function, for x number of tickets.

y = 3x+10

Hence, the required function is y = 3x+10

Find the sale price of the item. Round to two decimal places when

Original Price: $40.00; Markdown: 15%
$46
$34
$42
$32

Answers

First, determine what 15% of $40 is.

Convert 15% to a decimal: 0.15

Then multiply this decimal by $40: 0.15 x 40 = 6

So the discount is $6.

We subtract the discount from original price to get sale price.

40-6= 34

So the item will cost $34.
