Answer: An isosceles triangle has two sides of equal length. The length of one of the equal sides is two more than 3 times the length of the third side. If the perimeter is 46m, find the length of each side.

Step-by-step explanation:

Hope this helps!

Answer:

Step-by-step explanation:

The perimeter is equal to the lengths of all the sides.

Let x equal the two sides that are equal to each other.

Then the 3rd side is 2x - 1 which is 2 times the length of the equal side minus 1.

So the perimeter 23 = x + x + (2x-1)

Now solve for x

23 = x + x + 2x - 1

add 1 to both sides

24 = x + x + 2x

24 = 4x

x = 6

The two equal sides would be 6 feet each

The other side would be 2(6) - 1 = 11

The perimeter is 6 + 6 + 11 = 23

Step-by-step explanation:

Perimeter of the quadrilateral = sum of the length of all the four sides. Note: Missing side of the quadrilateral = Perimeter of the quadrilateral - Sum of the length of three sides.

Answer:

Slope intercept form (y = mx + b) = [tex]y = \frac{2}{3} x + \frac{7}{3}[/tex]

X intercept (slope): [tex](-\frac{7}{2} , 0)[/tex]

Y Intercept: [tex](0, \frac{7}{3} )[/tex]

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y and solve for  x.

To find the y-intercept, substitute in  0  for  x and solve for  y.

Hope this helps! :D

Step-by-step explanation:

solve for y

[tex]3y - 7 = 2x[/tex]

isolate the y variable to one side

let's first add 7 to both sides of the equation

[tex]3y - 7 + 7 = 2x + 7[/tex]

sevens on the left side of the equation cancel so we get

[tex]3y = 2x + 7[/tex]

Now let's divide everything in the equation by 3 to further isolate the y variable

[tex] \frac{3y}{3} = \frac{2x}{3} + \frac{7}{3} [/tex]

The threes on the left hand side of the equation cancel

[tex] y = \frac{2}{3}x + \frac{7}{3} [/tex]

Step-by-step explanation:

20 (20) + 400 = 400 + 400 = 800

10 (20) + 600 = 200 + 600 = 800

answer B = 20 guests

Answer:

For 20 persons the price would be same.

Step-by-step explanation:

y=y

20x+400=10x+600

20x-10x=600-400

10x=200

x=20

Therefore, for 20 persons the price would be same.

Answer:

9.53 AU

Step-by-step explanation:

Step-by-step explanation:

p : c

4 : 3 = x : 36

3x = 4 × 36

3x = 144

x = 48

p + c = 70

c = 3/7 × 70

c = 3 × 10

c = 30

Answer: You"ll earn $884 because we know that 707.20 divided by 32 equals 22.1 and 22.1x40 = $884. Therefore, you"ll make $884 for 40 hours.

Answer:

4:3

Step-by-step explanation:

ratio of H20 to Oil = (Amount of H20) / (Amount of Oil) = (2/3 cup)/(1/2 cup) =

(2/3) / (1/2) = (2/3) * (2/1) = 4/3 = 4:3

The 90% confidence interval is between R96.94 and R105.06

The confidence (C) = 90% = 0.9, Mean (μ) = 101, standard deviation (σ) = 39, sample size (n) = 250

α = 1 - C = 1 - 0.9 = 0.1

α/2 = 0.1 / 2 = 0.05

The z score of α/2 corresponds with the z score of 0.45 (0.5 - 0.05) which is equal to 1.645

The margin of error (E) is given by:

[tex]E=Z_\frac{\alpha }{2} *\frac{\sigma}{\sqrt{n} } \\\\E=1.645 *\frac{39}{\sqrt{250} } =4.06[/tex]

The confidence interval = μ ± E = 101 ± 4.06 = (96.94, 105.06)

Therefore the 90% confidence interval is between R96.94 and R105.06

Option 2

Step-by-step explanation:

Radians = 150 × π/180

=5π/6

Answer:

75

Step-by-step explanation:

Average needed to get grade C = 70

Average = Total Amount / No of Items.

No of items = 4

therefore Total needed = 70 x 4 = 280

current total score = 66.75 + 66 + 72.25 = 205

the fourth test minimum score = 280 - 205 = 75

Answer:

B. 0.210

Step-by-step explanation:

Range is the minimum value subtracted from the maximum value. In this case 0.004 is the smallest value and 0.214 is the largest.

Range = 0.214 - 0.004 = 0.210 = B

The range set of the given data is 0.21.

The given data sets are,

0.004

0.007

0.011

0.011

0.012

0.020

0.200

0.214

We know that,

In statistics, the range is the difference between the highest and lowest values for a given data collection.

For instance,

if the given data set is 2,5,8,10,3, the range is 10 - 2 = 8.

As a result, the range can also be defined as the difference between the highest and lowest observations.

The range of observation is the name given to the outcome. In statistics, the range indicates the dispersion of observations.

Now to find the range set pf the given data,

Subtract minimum value to maximum value

Since maximum value = 0.214

And minimum value     = 0.004

Then range set = 0.214 - 0.004

                          =  0.21

Thus, range of set  ⇒ 0.21

Answer:

81.75

Step-by-step explanation:

First, find the median of all the answers.

78.25,  77.75, and 84 = 80 (median)

now that we know 80 is the median, we will add it to our solution.

And still, there is no OTHER TEST in to make this stay 80.

78.25, 77.75, 84, and 80 = 79.125

since this is incorrect, we go higher.

78.25, 77.75, 84 and 81 = 79.625

since this is also incorrect, we go higher.

78.25, 77.75, 84 and 82 = 80.125

since this is higher and incorrect, we will go lower to 81.5.

78.25, 77.75, 84 and 81.5 = 79.875

since this is lower AND 82 is not the correct solution, we will go up by 0.25.

78.25, 77.75, 84 and 81.75 = 80

To check, we will do the problem again.

78.25, 77.75, 84 and 81.75 = 80

So, the solution is 81.75

Answer:

2.05

Step-by-step explanation:

1.25 + 0.8= 2.05 but if your doing multiplication then it would be 1 just 1.

Answer:

The answer would be , less than one .

The difference of 1.4 - 0.95 is less than one as per the concept of subtraction.

To determine this, we can simply subtract the two values:

1.4 - 0.95 = 0.45

Since the result of the subtraction is 0.45, which is less than one, we can conclude that the difference of 1.4 - 0.95 is indeed less than one.

In numerical terms, the difference is 0.45, which is 45 hundredths or less than half of one whole unit.

When comparing the two original values, 0.95 is almost half of 1.4, making the difference smaller than one.

In summary, the difference of 1.4 - 0.95 is less than one, specifically 0.45. It is essential to pay attention to the decimal values and their magnitudes when determining the difference between two numbers.
