Step-by-step explanation:

Answer:

Step-by-step explanation:

The following figure is a trapezium,

So Given,

Parallel sides of the trapezium = 17ft and 39ft

Height of the trapezium = 16ft

Therefore,

Area of the trapezium

[tex] = \frac{1}{2} \times (sum \: of \: parallel \: sides) \times height[/tex]

[tex] = \frac{1}{2} \times (17ft + 39ft) \times 16ft[/tex]

[tex] = \frac{1}{2} \times 56ft \times 16ft[/tex]

[tex] = 56ft \times 8ft[/tex]

[tex] = 448 {ft}^{2} [/tex]

Hence,

448 sq.ft is the area of the trapezium (Ans)

Answer:

If the one leaning wasn't leaning it would be the same height.

Step-by-step explanation:

If they are the same height and width (which they are) they have the same volume. Also, leaning shapes have the same volume as not leaning shapes.

Hope this helps you! :)

Answer:

sorry i dont know

Step-by-step explanation:

The mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg

Solution:

Let "a" be the mass of full grown giraffe

Let "b" be the mass of full grown lion

Let "c" be the mass of full grown cheetah

A full-grown giraffe is about 6 times heavier than a full-grown lion

a = 6b ------- eqn 1

A full-grown cheetah is about one-quarter as heavy as a full-grown lion

\begin{gathered}c = \frac{1}{4} \times b\\\\c = \frac{b}{4} ----- eqn\ 2\end{gathered}

c=

4

×b

c=

4

b

−−−−−eqn 2

Together, they are about 450 kg

Therefore,

a + b + c = 450

Substitute eqn 1 and eqn 2 in above

\begin{gathered}6b + b + \frac{b}{4} = 450\\\\24b + 4b + b = 450 \times 4\\\\29b = 1800\\\\b = 62.07\end{gathered}

6b+b+

4

b

=450

24b+4b+b=450×4

29b=1800

b=62.07

Substitute b = 62.07 in eqn 1

\begin{gathered}a = 6(62.07)\\\\a = 372.42\end{gathered}

a=6(62.07)

a=372.42

Substitute b = 62.07 in eqn 2

c = \frac{62.07}{4} = 15.51c=

4

62.07

=15.51

Thus, mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg

Answer:

(9,9)

Step-by-step explanation:

All you have to do is look down and across to the numbers. If you need help with the x and y here it is (x,y)

here is a trick to remember it "run x before you fly to y "

Answer:

i think it should be " (9,9) "

Step-by-step explanation:

Since it's asking for the coordinate points of the post office, it would be (x, y). The x-value where the post office on the grid is 9, and the y-value where the post office on the grid is also 9, so the coordinate points will be (9,9).

Hope this helps!

Answer:

10

Step-by-step explanation:

Answer:

24 ÷ 2 - 6 + 8 ÷ 2 = 10

Step-by-step explanation:

First, you do the divisions: (24 ÷ 2) - 6 + (8 ÷ 2)

Then you do everything left to right: 12 - 6 + 4

This gets you an answer of 10.

Answer:

3/10

Step-by-step explanation: you would count the total amount of marbles in the bag, which would be the denominator. Then you would count the amount of green marbles, which is 3, which would be the numerator. Your final answer would be 3/10.

Step-by-step explanation:

b+75+31=180

b+106=180

b=180-106

b= 74

a+b=180

a+74=180

a=180-74

a= 106

Answer:

2a. 5.8

2b. On average, a score will be 5.8 points away from the average score.

2c. The score will be about 2 points nearer to the average.

4a1. Sample 1 Mean: $2300; Sample 1 Median: $2250.

4a2. Sample 2 Mean: $5650; Sample 2 Median: $5600.

4b. The monthly cost of living is more expensive for a married couple w/ 1 child than for a single person.

Step-by-step explanation:

2a./2b.

In order to find the mean absolute deviation, we need to first find the mean.

(21 + 45 + 21 + 14 + 21 + 28 + 24 + 14 + 24 + 28)/10

(66 + 35 + 49 + 38 + 52)/10

(101 + 87 + 52)/10

(101 + 139)/10

240/10

The mean of this set is 24.

Now for the deviation.

For the mean absolute deviation, divide the combined value of the 10 deviation values from before (in absolute value) by 10.

(|-3| + 21 + |-3| + |-10| + |-3| + 4 + |-10| + 4)/10

(3 + 25 + 3 + 10 + 3 + 10 + 4)/10

(28 + 13 + 13 + 4)/10

(41 + 17)/10

58/10

The mean absolute deviation is 5.8. That interpreted would be like this: A score, on average, is 5.8 points away from the average score.

2c.

What I'll do here is the following: subtract 45 from 240, and then subtract 21 from the mean deviations. In both cases, I will now divide by 9.

(240 - 45)/9

195/9

65/3

The mean of the set (without 45) is now 21 2/3.

(58 - 21)/9

37/9

The new mean absolute deviation is 4 1/9, which rounds to 4.1. That's 1.7 points nearer to the average than originally.

So, without 45 as one of the scores, the M.A.D. decreases by about 2. That interpreted would be like this: The scores are about 2 points nearer to the average than before.

4a./4b.

First, I'll find the mean for sample one.

(1800 + 2000 + 2200 + 2300 + 2500 + 3000)/6

(3800 + 4500 + 5500)/6

(8300 + 5500)/6

13800/6

The mean for sample one is $2,300/month.

Now for the median for sample one. Since there are 6 values, add the two middle values and divide by 2.

(2200 + 2300)/2

4500/2

The median for sample one is $2,250/month.

Now for the mean & median for sample two.

Mean:

(5400 + 5500 + 5600 + 5600 + 5800 + 6000)/6

(10900 + 11200 + 11800)/6

(22100 + 11800)/6

33900/6

The mean for sample two is $5,650/month.

Median:

Again, there are 6 values. However, this time they are the same, so there is no need to divide. The median for sample two is $5,600/month.

Looking at the data, the mean & median for sample was larger than sample one. Thus, I can conclude the following: The monthly cost of living is more expensive for a married couple w/ 1 child than for a single person.

Answer:

Try maybe making it into a half circle

Step-by-step explanation:

Answer:

hey that guy or girl or person is not wrong because C is litterly a half circle

Step-by-step explanation:

Answer:explained in the comments but its 8 and 1/4

Step-by-step explanation:because the yaxis on the first is negative and your finding the distance we can make it the absolute value of both points

[tex]|-3\frac{3}{4} |+|4\frac{2}{4} | = 8 \frac{1}{4}[/tex]|-3 3/4|+|4 2/4|=8 and 1/4

Answer:

8 1/4 OR 8.25

Step-by-step explanation:

distance formula: [tex]\sqrt{(x2 - x1)^{2}+(y2 - y1)^{2} }[/tex]

=> [tex]\sqrt{(-1 + 1)^{2} + (4 \frac{1}{2} + 3\frac{3}{4} )^{2} }[/tex]

=> √(8 1/4)²

=> 8 1/4 OR 8.25

Answer: x= 41

Explanation: Angles 1 and 2 have to equal 180° since they are supplementary. So you put 3x+2x-25=180, you then add like terms. 5x-25=180 Then you have to isolate x, so you add 25 to both sides of the equation. 5x=205, then you divide both sides by 5. So your answer is x=41.

You can check to make sure by plugging in x for 41 .

Answer:

Minimum: 4

Quartile:5

Median:8

Quartile:11

Maximum:12

Step-by-step explanation:

you write down the numbers in order from least to greatest. The median is the number in the middle. then you split the numbers in half in the middle. then you find to two halves Middle number witch is the Quartile. Minimum is the smallest number Maximum is the greatest

Answer:

Total Cost/Price including ST: $48.60

Step-by-step explanation:

Answer:

x = 90

Step-by-step explanation:

Since we know 180° is a straight line we can subtract 70° to get the angle next to it.

180° - 70° = 110°

Now we know 110° = (x - 20)°

20 - 110 = x - 20 - 20

90 = x

Answer:

First one: x = 3, and y = 2

Second: 5

Third: Yes because he will have $37.50

Fourth: The numbers 2.5 and 3 will make it true

Step-by-step explanation:

1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19

2. 4x + 2 = 22, 4x = 20, x = 5

3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5

He will get $37.50, which is enough.

4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.
