Answer:

x1=-5/2, x2=1

Step-by-step explanation:

Answer:

x1=-5/2, x2=1

Step-by-step explanation:

because if you use quadratic formula

you would have x = -3 + or - √3^2 -4 x 2 x (-5)/ 2 x 2

simply and combine like terms give you

x = -3 + 7 / 4

x = -3 - 7 / 4

then you get

x = 1

x = -5/2

Step-by-step explanation:

Penny stocks are very cheap stocks

Answer:

The answer is "[tex]4 \cdot 7[/tex]".

Step-by-step explanation:

In the question the total given value =4(x+7).  if we add the value it will be 11 but if we multiply the value it is equal to [tex]4 \cdot 7[/tex].

The error gardener made is that the area of the extended portion is 28 ft² instead of 11 ft².

Given to us

The original length of the garden is x.

The Area of the extended garden is 4(x+7).

Given to us is the area of the complete garden, therefore, comparing the expression with the area of a rectangle,

[tex]\text{Area of rectangle}= \rm{ Breadth \times Length[/tex]

[tex]4(x+7) = Breadth \times Length[/tex]

Therefore, the breadth of the rectangle is 4 feet, since the breadth of the rectangle is not been changed the breadth of the rectangle is same as before, also (x+7) represents the complete length of the garden after it is extended, and since the original length of the garden is x, the length extended is 7 feet.

We know that the breadth of the rectangular garden is 4 and the area of extended length is 7, therefore,

The Area of the only Extended Portion of the Garden

= 4 x 7 = 28 ft²

Hence, the error gardener made is that the area of the extended portion is 28 ft² instead of 11 ft².

Answer:

(11+w)/4

Step-by-step explanation:

Let the first term be 3 miles

If he plans to increase the distance of his run by 1/4 mile, then

common difference = 1/4

To get the distance Kane runs in a training session after w weeks , we will use the nth term of an AP

Tw = a+(w-1)d

Tw = 3 + (w-1)(1/4)

Tw = 3 + 1/4 w - 1/4

Tw = 11/4 + 1/4 w

Tw = (11+w)/4

Hence the distance Kane runs in a training session after w weeks is (11+w)/4 weeks

Answer:

2.24

Step-by-step explanation:

The rate of decrease at 10 seconds is - 0.642.

The formula for exponential growth is y = y₀.e^(kt).

The formula for exponential decay is y = y₀.e^(-kt).

From the graph, we conclude that it is an exponentially decaying function.

At t = 10, depth = 60 and at t = 0 depth = 112

                                                                   (as every box represents 4 units).

So, the rate of decrease can be obtained by,

112 = 60.e^(-10k).

e^(-10k) = 1.86.

lne^(-10k) = ln1.86.

- 10k = 6.42.

k = - 0.642.

The rate of decrease at 10 seconds is - 0.642.

Answer:

The value of x is 67.5

Step-by-step explanation:

The sum of the measures of the angles around a point is 360°

Let us solve the question

∵ In the given figure there are 3 adjacent angles around one vertex

→ By using the rule above

∴ The sum of their measures is 360°

∵ One of the angles is a right angle

∵ The measure of the right angle is 90°

∵ The measures of them are x, 3x, and 90°

∴ x + 3x + 90° = 360°

→ Solve the equation by adding the like terms to find x

∵ (x + 3x) + 90 = 360

∴ 4x + 90 = 360

→ Subtract 90 from both sides

∵ 4x + 90 - 90 = 360 - 90

∴ 4x = 270

→ Divide both sides by 4

∴ x = 67.5

∴ The value of x is 67.5

Step-by-step explanation:

Answer:

B and D

Step-by-step explanation:

First off, we can rotate it. When rotating, I found that the x and y values switch places in a way.

We would need to rotate it 90 degrees counterclockwise about the origin in order to get it in the same position as triangle BDE. This makes statement B correct.

In order to make triangle ABC smaller, the dilation would have to be smaller than one. Counting the right side's length, ABC has 6 squares and BDE has 3.

This would mean 6 * 1/2 = 3, meaning statement D is true.

Answer:

35 boys

Step-by-step explanation:

Answer:

15/35 or 43% if your going to the nearest whole number so there are 35 boys and 15 girls

Step-by-step explanation:

Let x = the number of boys

Let 50 - x = the number of girls

Girls/Boys: 3 = 50 - x       Cross Multiply

                   7        x

3x = 350 - 7x

10x = 350

x = 35 boys

50 - x = 15 girls

Check: 15/35 = 3/7

Answer:

6:54

Step-by-step explanation:

Correct time set = 10 am

Correct time after 3 hours = 10 am + 3 hours

= 1 pm

Steven watch after 3 hours = 12:54

This means Steven watch is 6 minutes behind the normal time

If Stephen does not adjust his watch, at what time on his watch should he show up at the restaurant for a 7 o' clock date with Mabel?

Time Stephen show up for date with Mabel = 7:00 - 6 minutes

= 6:54

Answer:

22.99 inches

Step-by-step explanation:

According to problem, given data are as follows:

Fabric used for headband = 595.56 inches

Number of headbands made = 39 + 3 = 42

So, Fabric used per headband = 595.56 ÷ 42 = 14.18 inches per headband

Similarly, Fabric used for wristband = 343.59 inches

Number of wristbands made = 39

So, Fabric used per wristband = 343.59 ÷ 39 = 8.81 inches per wristband

So, Fabric used for each player = 14.18 inches + 8.81 inches

= 22.99 inches
