Answer: The answer is 580

Step-by-step explanation: you first do the front side which is 20 x 10 which is 200. You multiply 200 by 2 since the front and back are the same.

then you move on to the sides.

the bottom of the side is 3. The height is 20. 3 x 20 is 60. Since there are 2 sides, you will do 60 x 2 which is 120.

now we move on too the top. The width of width is 3. and the length is 10. 10 x 3 is 30. Since the bottom is also the same, you do 30 x 2. You add all the numbers.

So 400 (from the front and back) + 120 (from the sides) + 60 ( from the top and bottom)

thiss all equals 580. sorry if it is a bit confusing I just understood it too. I am 14 trying to get math a year above me.

Answer:

The scientist used the experimental statistical study.

Step-by-step explanation:

Statistical study is the process of collecting, analyzing and presentation of data to achieve an accurate conclusion. The major types are: survey, and experimental.

Survey statistical study can easily be achieved by the use of questionnaires to sample the opinion of participants. While experimental statistical study involve the participants observing a process or some procedures before conclusions can be made.

In the given question, the scientist performed an experiment by asking participant to undergo a process before making his conclusion. Thus, he used an experimental statistical study.

Answer:

As shown in picture:

angle A = angle B

or

8x + 6 = 4x + 38

=> 4x = 32

=> x = 8

=> B = 4*x + 38 = 4*8 + 38 = 32 + 38 = 70 deg

Answer:

[tex]B = 70 \: \: degrees[/tex]

Step-by-step explanation:

[tex]8x + 6 = 4x + 38 \\8 x - 4x = 38 - 6 \\ 4x = 32 \\ \frac{4x}{4} = \frac{32}{4} \\ x = 8[/tex]

[tex]4x + 38 \\ 4 \times 8 + 38 \\ 32 + 38 \\ = 70 \: \: degrees[/tex]

Answer:

10.89

Step-by-step explanation:

Circle:

C = TTD

C = TT(6.6)

C = 20.73451151

C = 20.73

Triangle:

A = bh/2

A = 6.6(3.3)/2        6.6/2=3.3

A = 21.78/2

A = 10.89

Shaded Region = 10.89

Answer:

B, C ,E

Step-by-step explanation:

B <2 = <6  they are alternate interior angles

C <1 + <6 = 180  <1 + 75 = 180  and 75 and <6 are equal because they are corresponding angle so <1 + <6 = 180

E x = 120

<1 + <6 = 180

<1 + 75 = 180

<1 = 105

<1 =x-15

105 = x-15

Add 15

120 =x

Answer:

original price = 105.66

Step-by-step explanation:

35% off means she pays 100-35 = 65%

original price * 65% = 68.68

Change to decimal form

original price *.65 = 68.68

Divide each side by .65

original price *.65/.65 = 68.68/ .65

original price = 105.66

Answer:

A & C

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles

Answer:

Triangles A and C are congruent.

Step-by-step explanation:

Congruent triangles are when two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The total of the angles of all triangles is 180, so then add all the angles then subtract that number from 180.

A: 110+30=140 (180-140=40)

B: 30+45=75 (180-75=105)

C: 110+40=150 (180-150-30)

Since Triangles A and C have the same angles, then they are congruent!!!

Answer:

(x + 3)(5x + 2)

Step-by-step explanation:

[tex] {x}^{2} - 12x + 35 \\ {x}^{2} - 7x - 5x + 35 \\ = x(x - 7) - 5(x - 7) \\ = (x - 7)(x - 5)[/tex]

Step-by-step explanation:

p(A|B) = p(A and B) / p(B) =(1/5) / (2/9) = 0.9

The probability that event A occurs is 5/8 , the probability that event B occurs is 2/9 , and the probability that events A and B both occur is 1/5 . The probability that A occurs given that B occurs is 0.9.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

The probability that event A occurs is 5/8

The probability that event B occurs is 2/9

The probability that events A and B both occur is 1/5.

So, The probability that A occurs given that B occurs

P(A|B) = P(A and B) / P(B)

          = (1/5) / (2/9)

          = 0.9

Answer:

28 rabbits

Step-by-step explanation:

From the statement, you can write the following:

d+c+r= 126

d=dogs

c= cats

r= rabits

Then, you have that there are 13 cats and that three fourths of the remaining animals are dogs:

c=13

d=(126-13)*(3/4)= 113*(3/4)= 85

Now, you can isolate r, to find the number of rabbits:

r=126-d-c

r= 126-85-13

r= 28

According to this, the are 28 rabbits.

Step-by-step explanation:

Answer:

£800

Step-by-step explanation:

For this question we need to utilise decimal multiplier. Since this is a decrease question to work out the decimal multiplier you have take 100 away from the percentage and then divide by 100. If this was an increase question then we would had to add 100 to the percentage and then divide by 100. Since the question is asking for the price before the decrease we are going to have to divide the multiplier by the price so,

⇒ Work out the multiplier by taking 100 away from the percentage and then dividing by 100

→ 100 - 20 = 80  ↔  80 ÷ 100 = 0.8

⇒ The multiplier is 0.8, now we have to divide the multiplier by the price

→ 640 ÷ 0.8 = 800

The price of a washing machine was decreased by 20% to £640. The price before the decrease was £800

Answer:

42

Step-by-step explanation:

Answer: It would be 42 Centimeters! :D

Answer:

If two vectors are parallel, applying the same side interior angles theorem:

=> 80 + a + 59 = 180

=> a = 180 - 80 - 59 = 41 deg

Answer:

7 gallons of water were bought

Step-by-step explanation:

This question can be solved using a rule of three.

One gallon costs $1,500. How many gallons cost $10,500?

1 gallon - $1,500

x gallons - $10,500

[tex]1500x = 10500[/tex]

[tex]x = \frac{10500}{1500}[/tex]

[tex]x = 7[/tex]

7 gallons of water were bought

Answer:

a) t=5

5+5+5=15

b) x=11

11-8=3

or you can add 3 to both sides and x=11

c) w=3

7(3) = 21

21+3=24

or subtract 3 from both sides to get 7w=21

then divide by 7 on both sides to get w=3

Answer:

a) t = 5

b) x= 5

c) w= 3

Answer:

Small scooters = 6

Large scooters = 4

Step-by-step explanation:

Let S represents small scooter and L represents large scooter

The cost of a small scooter is £80

Mathematically,  the cost of S number of small scooters is

80S

The cost of a large scooter is £130

Mathematically,  the cost of L number of large scooters is

130L

The total amount spent on both scooters is £1000

Mathematically,

80S + 130L = 1000

So we have 2 unknowns and only 1 equation. Therefore, we have use trial and error method .

Trial and Error Method:

80S + 130L = 1000

80S = 1000 - 130L

S = (1000 - 130L)/80

Let’s suppose they bought 1 large scooter

S = (1000 - 130(1))/80

S = 10.875

Number of scooters cannot be in fraction so 1 doesn’t work

Let’s suppose they bought 2 large scooter s

S = (1000 - 130(2))/80

S = 9.25

Number of scooters cannot be in fraction so 2 doesn’t work

Let’s suppose they bought 3 large scooter s

S = (1000 - 130(3))/80

S = 7.625

Number of scooters cannot be in fraction so 3 doesn’t work

Let’s suppose they bought 4 large scooters

S = (1000 - 130(4))/80

S = 6

So that means they bought 6 small scooters and 4 large scooters.

Similarly, other combinations for scooters don’t work since they yield either fractional value or negative value which cannot be correct.

Therefore, the only possible combination of small and large scooters is

6 Small scooters

4 Large scooters

Verification:

80S + 130L = 1000

80(6) + 130(4) = 1000

480 + 520 = 1000

1000 = 1000 (satisfied)
