Answer:

Figure 4: Square

Figure 1: Parallelogram

Figure 2: Rectangle

Step-by-step explanation:

Question 1: If they're not similar it can't be the same shape but if they have the same corresponding angles it has to be either a rectangle or a square. It can't be a rectangle so it must be a square.

Question 2: Can't be similar so it can't be the same shape. The only two shapes with side lengths proportional are the parallelogram and the rectangle. It can't be the rectangle so it must be the parallelogram.

Question 3: If it's similar it has to be the same shape so the answer must be the rectangle.

Jessica, who reads at a speed of 3 pages per minute, can read 360 pages in 2 hours.

The subject of this question is mathematics, answered by a simple multiplication operation. Jessica loves to read and reads at a speed of 3 pages per minute. We know that there are 60 minutes in an hour, so in 2 hours, there are 2 * 60 = 120 minutes. Now, if Jessica reads 3 pages per minute, in 120 minutes, she would read 120 * 3 = 360 pages. Therefore, Jessica can read 360 pages in 2 hours at her reading speed.

Answer:

After 50 years the stock value will be $50 per share.

Step-by-step explanation:

Simple Interest Equation (Principal + Interest)

A = P(1 + rt)

Where:

A = Future amont = $50

P = Principal Amount = $40

r = Rate of Interest per year in decimal; r = R/100 = 0.5/100 = 0.005

t = Time Period involved in months or years  

Plug in the values

50 = 40(1 + 0.005t)

50 / 40 = (1 + 0.005t)

5/4 = 1 + 0.005t

5/4 - 1 = 0.005t

0.25 = 0.005t

t = 0.25 / 0.005

t = 50 years

Answer:

44. 7 yr

Step-by-step explanation:

The compound interest equation is

[tex]A = P(1+ \frac{r }{ n})^{nt}[/tex]

You don't give the frequency of compounding, so I will assume that it is once per year.

Data:

P = $40

r = 0.5 % = 0.005

n =1  

Calculations:

(a) Calculate A

A = P + I = 40 + 10 = $50

(b) Calculate t

[tex]50 = 40(1+ \frac{0.005 }{ 1})^{1 \times t}\\50 = 40(1+ 0.005)^{t}[/tex]

Divide each side by 40

[tex]1.25 = 1.005^{t}[/tex]

Take the logarithm of each side

 log1.25 = tlog1.005

0.09691 = 0.002 166t

Divide each side by 0.002 166

t = 44.7 yr

The value of the stock will be $50 in 44.7 yr.

Step-by-step explanation:

Employees need to stock at least 42 each day for a whole week or work. (5 days) so wee need to find how much they need to stock in a week.

42 x 5 = 210.

So They need to stock 210. Employee A has already stocked 185. so we need to take 185  from 210 to see how MORE he needs to stock.

210 - 185 = 25.

25.

Hope this helped! Please mark as brainliest! THanks!

In order to be able to make the goal that was set for the employee, the employee would have to re-stock 25 products.

The worker is supposed to stack an average of 42 products from Monday to Friday which is 5 days.

Technically speaking, in every one of those 5 days, 42 products should be stocked. The total for the week is therefore:

= 5 days x Number of products stocked per day

= 5 x 42

= 210 products

The worker has stocked 210 products already and so is left with:

= Number to be stocked - Number already stocked

= 210 - 185

= 25 products

In conclusion, the worker still has to re-stock 25 products.

The correct option is B.

Step-by-step explanation:

From the given figure it is clear that triangle LMN is a right angled triangle.

According to Pythagoras theorem: In a right angled triangle

[tex]hypotenuse^2=perpendicular^2+base^2[/tex]

In triangle LMN,

[tex]LN^2=LM^2+MN^2[/tex]

[tex](\sqrt{20})^2=x^2+(x-2)^2[/tex]

[tex]20=x^2+x^2-4x+4[/tex]

[tex]20=2x^2-4x+4[/tex]

Subtract 20 from both sides.

[tex]0=2x^2-4x+4-20[/tex]

[tex]0=2x^2-4x-16[/tex]

Taking out common factors.

[tex]0=2(x^2-2x-8)[/tex]

Splitting the middle term we get

[tex]0=2(x^2-4x+2x-8)[/tex]

[tex]0=2(x(x-4)+2(x-4))[/tex]

[tex]0=2(x-4)(x+2)[/tex]

Using zero product property we get

[tex]x-4=0\Rightarrow x=4[/tex]

[tex]x+2=0\Rightarrow x=-2[/tex]

The value of can not be negative because side of a triangle is always positive. So, the value of x is 4.

Therefore the correct option is B.

sin, cos, sec, csc  

Step-by-step explanation:

If the terminal side passes through (-1, -1), the angle θ = 225° and is in the third quadrant.

sinθ = opp/hyp = -/+  =  -

cosθ = adj/hyp  = -/+ =  -

tanθ = opp/adj  = -/-  = +

cotθ = adj/opp  = -/-  = +

secθ = 1/cosθ            =  -

cscθ = 1/sinθ             =  -

The functions that will be negative for the angle are sin, cos, sec, and csc.

Step-by-step explanation:

20%x50=10

Final answer:

To find the number of left-handed players on the sports team, 20% of the 50 total players is calculated, which equals 10 left-handed players.

Explanation:

To calculate the number of left-handed players on a local sports team where 20% of the players are left-handed, you need to apply the percentage to the total number of players. If there are 50 players in total, you would calculate 20% of 50:

Convert the percentage to a decimal by dividing it by 100. So, 20% becomes 0.20.

Multiply this decimal by the total number of players to find the number of left-handed players: 0.20  imes 50 = 10.

Therefore, there are 10 left-handed players on the team.

Answer: The graph is attached.

Step-by-step explanation:

1. Solve for y, as following:

[tex]10x+7y<49\\7y<-10x+49\\y<-\frac{10}{7}x+\frac{49}{7}\\\\y<-\frac{10}{7}x+7[/tex]

2. The equation of the line in slope intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

3. In this case the equation of the line is:

[tex]y=-\frac{10}{7}x+7[/tex]

then:

[tex]m=-\frac{10}{7}\\\\b=7[/tex]

4. Find the x-intercept. Make y=0. Then:

[tex]0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9[/tex]

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).

6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.

Then you obtain the graph attached.

Answer:

We need to graph the given inequality 10x + 7y < 49.

We can do that into 2 parts:

Part 1:

Graph the line 10x+7y=49

plug any number for x say x=0

10x+7y=49

10(0)+7y=49

0+7y=49

7y=49

y=49/7

y=7

hence it passes through point (0,7)

similarly plug y=0

10x+7(0)=49

10x=49

x=49/10

x=4.9

hence it passes through point (4.9,0)

Graph both points then join them by a straight dotted line because of < sign.

PART 2:

Shade the graph for inequality sign <

use any test point which is not on the given line say (0,0)

plug into original problem

10x + 7y < 49

10(0) + 7(0) < 49

0<49 is true

so shade in direction of test point

Hence final graph looks like:

Answer:

The equation of the hyperbola in standard form is

[tex]\frac{y^{2}}{100}-\frac{4x^{2}}{625}=1[/tex]

Step-by-step explanation:

* We will take about the standard form equation of the hyperbola

- If the given coordinates of the vertices (0 , a) and (0 , -a)

∴ The transverse axis is the y-axis. (because x = 0)

- If the given asymptotes at y = ± (b/a) x

∴  Use the standard form  ⇒ y²/a² - x²/b² = 1

* Lets use this to solve our problem

∵ The vertices are (0 , 10) and (0 , -10)

∴ a = ±10

∴ a² = 100

∵ The asymptotes at y = ± 5/4 x

∴ ± 5/4 = ± b/a

∵ a = ± 10

∴ ± 5/4 = ± b/10 ⇒ using cross multiplication

∴± (4b) = ± (5 × 10) = ± 50 ⇒ divide both sides by 4

∴ b = ± 25/2

∴ b² = 625/4

* Now Lets write the equation

* y²/100 - x²/(625/4) = 1

∵ x² ÷ 625/4 = x² × 4/625 = (4x²/625)

∴ y²/100 - 4x²/625 = 1

* The equation of the hyperbola in standard form is

  [tex]\frac{y^{2}}{100}-\frac{4x^{2}}{625}=1[/tex]

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x+1)^2 + (y-6)^2 = 3^2

Answer: April is correct.

Step-by-step explanation: According to the methods used in systems of equations, if we are to solve this system by setting up the equations

(3 = -2x + 1), we see that the solution is x = -1. If you substitute this x-value back into the original equation, y = -2x + 1, we get the answer y = 3 and thus, receiving the solution to the system (-1,3). Anthony is wrong because the graph includes an extra line at x = 3, throwing off his answers.
