On Monday the temperature is 68°. On Wednesday the temperature is expected to be 80°. What is the percent of change in temperature to the nearest percent?

Answer:

Length of the base of the given parallelogram is 14 units

Step-by-step explanation:

This question is incomplete; Find the complete question in the attachment.

Area of the parallelogram (A) = 140 square units

Height of the parallelogram (h) = 10 units

Since area of the parallelogram = Base × height

A = b × h

140 = b × 10

b = [tex]\frac{140}{10}[/tex]

b = 14 units

Therefore, length of the base of the given parallelogram is 14 units.                                    

Answer:

14 units is the answer I got it right on khan academy.

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:

[-1,3) domain i think the video i am watching kinda confusing tell me if i am right

[3,-5) range like i said tell me i got it wrong

Step-by-step explanation:

The domain and the range of a graph is the possible x and y values, the graph can take.

First, we determine the domain.

On the x-axis, the curve starts from x = -1 with a closed circle, and it ends at x = 3, with an open circle

A closed circle is represented by [tex]\ge[/tex] or [tex]\le[/tex], while an open circle is represented > or <

So, the domain of the graph is: [tex]-1 \le x < 3[/tex]

Next, we determine the range.

On the y-axis, the curve starts from y = 3 with a closed circle, and it ends at y = -5, with an open circle

Using the explanation of open and closed circle above,

The range of the function is: [tex]3 \ge y > -5[/tex]

Hence, the domain and the range of the graph are: [tex]-1 \le x < 3[/tex] and [tex]3 \ge y > -5[/tex], respectively.

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:

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

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!!!

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: 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:

Average size of the lots = ⅓ acre

Step-by-step explanation:

The question incomplete without specifying what we are to determine.

Question:A builder is buying property where she can build new houses. The line plot shows the sizes for each house. 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X's. Organize the information in a line plot. What is the average size of the lots? _________ acre

Help anyone?

Solution:

We are asked to organize the information in a line plot. See attachment for the line plot.

Given: 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X'sIn no particular order, the sizes of the lots are:1/6, 1/6, 1/6, 1/6, 1/6, 1/6, 1/3, 1/3, 1/3, 1/2, 1/2, 1/2, 1/2, 1/2 and 1/2 acre.

Let's count the number of lot for each size given.

For 1/6: there are 6 X's on the line plot of 1/6 number of lot for 1/6

= the lot × number of times it occurs

= (1/6) × 6 = 6/6 = 1 acre

For 1/3: there are 3 X's on the line plot of 1/3 number of lot for 1/3 = the lot × number of times it occurs

= (1/3) × 3 = 3/3 = 1 acre

For 1/2: there are 6 X's on the line plot of 1/2 number of lot for 1/2

= the lot × number of times it occurs

= (1/2) × 6 = 6/2= 3 acres

To find average size of the lots, we would sum all lot for each given size then divide by the total number of lots given.Sum of all lot for each given size = 1+1+3

Sum of all lot for each given size = 5

The total number of lots given = 15

Average size of the lots = 5/15 = 1/3

Average size of the lots = ⅓ acre
