Answer:

768 in²

Step-by-step explanation:

Surface Area = 2(15*14) + 2(15*6) + 2(14*6)

Surface Area = 2(210 + 90 + 84)

Surface Area = 2(384)

Surface Area = 768

Answer:

yes they are congruent

Step-by-step explanation:

they have congruent sides to each other

The given figures are congruent.

Given are two figure ABCD and EFGH on a cartesian plane, we need to check if the figures are congruent or not,

The coordinates of the figure ABCD are:
A = (-1, 1), B = (-3, 2), C = (-4, 4) and D = (-2, 6).

The coordinates of the figure EFGH are:
E = (2, 0), F = (4, 1), G = (5, 3) and H = (3, 5).

To check if the figures ABCD and EFGH are congruent, we need to compare the corresponding sides and angles of the two figures.

Congruent figures have the same shape and size, so their corresponding sides must be equal.

Let's compare the corresponding sides of ABCD and EFGH, using the distance formula:

[tex]|D| = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

AB and EF:

[tex]|AB| = \sqrt{(-3+1)^2 + (2-1)^2}\\\\ |AB| = \sqrt{-2^2+1^2} \\\\ |AB| = \sqrt{5}[/tex]

And,

[tex]|EF| = \sqrt{(4-2)^2 + (1-0)^2}\\\\ |EF| = \sqrt{2^2+1^2} \\\\ |EF| = \sqrt{5}[/tex]

∴ AB = EF

Similarly,

[tex]BC =\sqrt{\left(-4-\left(-3\right)\right)^2+\left(4-2\right)^2}\\\\ BC = \sqrt{5}[/tex]

And,

[tex]FG =\sqrt{\left(5-4\right)^2+\left(3-1\right)^2}\\\\ FG = \sqrt{5}[/tex]

[tex]CD = \sqrt{\left(-2-\left(-4\right)\right)^2+\left(6-4\right)^2} \\\\ CD = 2\sqrt{2}[/tex]

And,

[tex]GH=\sqrt{\left(3-5\right)^2+\left(5-3\right)^2}\\\\ GH=2\sqrt{2}[/tex]

[tex]AD =\sqrt{\left(-2-\left(-1\right)\right)^2+\left(6-1\right)^2}\\\\ AD =\sqrt{26}[/tex]

And,

[tex]EH = \sqrt{\left(3-2\right)^2+\left(5-0\right)^2}\\\\EH =\sqrt{26}[/tex]

Therefore, we get,

FG = BC, GH = CD and AD = EH = √26.

Since we get all the corresponding sides are equal.

Hence the figures are congruent.

Answer:

median is 2

Step-by-step explanation:

I arranged the numbers from low to greatest and found the "middle" number basically

Answer:

2

Step-by-step explanation:

In order to find the Median of a data set, you must first put the numbers in the data set in order so you'd get:1, 1, 1, 1, 2, 2, 4, 6, 6, 8, 48 Then you would count on each side to the middle and whichever digit is in the middle that is your median.

Answer:

B, 33%

Step-by-step explanation:

Let us find the original price of four chairs without the special deal, and compare it with the deal to find the percent savings.

Step 1:

A customer must buy 4 chairs costing $75 each to recieve the deal. Let us multiply 4 by 75 to find the total cost without the deal:

[tex]4*75=\\300[/tex]

Step 2:

We now know the original cost of the 4 chairs, and the price of 4 chairs with a deal. Let us subtract the difference of costs and convert it into a percentage to find percent savings:

[tex]300-200=100\\\frac{100}{300} =\frac{1}{3}[/tex]

[tex]\frac{1}{3}=33[/tex]%

Therefore, B, the percent savings is 33%.

Answer: 1/10

Step-by-step explanation: These two events are independent, meaning the outcome of the first event doesn't affect the outcome of the second.

To find the probability of independent events, first, find the

probability of each event, then multiplies the probabilities.

The probability of spinning an A on the first spinner is 1/5

since there is 1 favorable outcome and 5 total outcomes.

The probability of spinning an odd number on the second spinner

is 3/6 which simplifies to 1/2 since there are 3 favorable outcomes,

spinning a 1, 3, or another 3 since these are odd numbers.

So now we have 1/5 × 1/2 and when multiplying fractions,

we multiply across the numerators and denominators to get 1/10.

So the probability of spinning an A, then an odd number is 1/10.

Answer:

firstly a triangle has angle sum of 180°

Step-by-step explanation:

let all the three angles be x,y and z such that x+y+z =180°

let x= 58° and y =59°

the to calculate for the unknown z angle ;

make z subject of the formula

thus z= 180° -x-y

> z= (180-58-59)°

z= 180-117

z= 63°

Answer:

63

Step-by-step explanation:

59 + 58 = 117

180 - 117 = 63

To find a third angle you will subtract the sum of the two given angles from 180 because all you have to know is that all of the angles in a triangle always add up to 180°.

Answer:

GJI = 242.67

Step-by-step explanation:

A circle is 360 degrees

GI + GJI = 360

The arc length is the same as the angle when it is at the center

117.33 + GJI = 360

GJI = 360 - 117.33

GJI = 242.67

Answer:

GJI = 242.67

Step-by-step explanation:

GI + GJI = 360

117.33 + GJI = 360

GJI = 360 - 117.33

GJI = 242.67

Answer:

Here, given

g(x) = √x

h(x) = x³-1

For gh(4) , we have to find gh(x), so,

gh(x) = g(x³-1)

        =√x³-1 [Note⇒root is both for x³ and 1]

Now,

gh(4) = √4³-1

        = 3√7 or 7.9

option B : Upen

Step-by-step explanation:

To find who saves the greatest. Find who spent the least.

That is find the smallest of these fractions.

Step 2 : to make denominators same find LCM of 8, 4, 3, 6

Step 3: LCM = 24

[tex]\frac{7}{8}\ , \frac{3}{4} \ , \frac{2}{3} \ , \frac{5}{6}[/tex]

[tex]\frac{7 \times 3}{8 \times 3}, \ \frac{3 \times 6}{4 \times 6} , \ \frac{2 \times 8 }{ 3 \times 8} ,\ \frac{5 \times 4}{6 \times 4}\\\\\frac{21}{24}, \ \frac{18}{24}, \ \frac{16}{24}, \ \frac{20}{24}\\\\Arranging\ the \ fractions \ in \ ascending \ order \ to \ find \ the \ least \ spent .\\\\\\frac{16}{24} , \ \frac{18}{24} , \ \frac{20}{24}, \frac{21}{24}[/tex]

So 2/3 is the smallest fraction,  which means 2/3 spent the least amount from the salary.

Therefore, Upen saves the greatest amount every month.

Both angles are congruent because they are opposite exterior angles.

6x+2=x+17

5x=15

x=3

Answer:

x = 23 °

Step-by-step explanation:

6 x + 2 ° + x + 17 ° = 180 °

combine like terms

6x + x + 2 ° + 17 ° = 180 °

7 x + 19 ° = 180 °

7 x = 180 ° - 19 °

7 x = 161 °

x = 161 ° / 7

x = 23 °

86,664 randomly selected U. S Adults

Step-by-step explanation:

The sample is a subset of the population, that is a representative observation which is chosen from a larger population usually used in place of the population due to various reasons which may hamper the use of the entire population on a certain research project. Here, the population of interest is the entire U.S adult.

The subset of the population employed is the 86,664 randomly sampled US adults, this is called the sample as it representative of the population of interest.
