Answer:

3 cm by 6 cm

Step-by-step explanation:

Represent the length and width by L and W.  

The perimeter is P = 2L + 2W, and here the perimeter is 18 cm.

Finally, L = W + 3 cm.  substituting W + 3 cm for L in the above equation, we get:

18 cm = 2(W + 3) + 2W, or (after reduction)

9 cm = W + 3 cm + W

Then 2W = 6 cm, or W = 3 cm.

Then the length is L = W + 3, or 3 cm + 3cm = 6 cm

The dimensions of the rectangle are 3 cm by 6 cm.

Check:  Does 2(3 cm) + 2(6 cm) = 18 cm?  Yes

Answer:

The range of the data is 9.

Step-by-step explanation:

The frequency table shown is:

Age     Tally          Frequency

24         |                     1

25         ||                    2

26        |||||                  5

27        ||||                   4

28         -                     0

29        ||||                   4

30        |||||                  5

31         |||                   3

32        ||||                   4

33                              13

The range of a data set is the difference between the highest and the lowest value.

Range = Maximum - Minimum

           = 33 - 24

           = 9

Thus, the range of the data is 9.

2 and 30 means the extremes and 3 and 20 are the means

Answer:

If angle 2 = 110 then angle 4 = 110

360 = 110 + 110 + x

Angle 1 + Angle 3 = 140

Since vertical angles are equal, then Angle 1 = 140 / 2 = 70 degrees

Step-by-step explanation:

Step-by-step explanation:

∠3+∠4= 180°

Since ∠2 ≅ ∠ 4 and  ∠2= 110°

∠3= 180° - ∠4= 180° - ∠2= 180° - 110°= 70°

So proved

Answer:

x = 8

[tex] m\angle A= 30\degree[/tex]

Step-by-step explanation:

By interior angle on one side of transversal postulate.

[tex] m\angle A + m\angle B = 180\degree \\

\therefore (6x - 18)\degree + (14x + 38)\degree = 180\degree \\

\therefore (20x + 20)\degree = 180\degree \\

\therefore 20x + 20 = 180

\therefore 20x = 180 - 20\\

\therefore 20x = 160\\\\

\therefore x = \frac {160}{20}\\\\

\huge \red {\boxed {\therefore x = 8}} \\\\

\because m\angle A= (6x - 18)\degree \\

\therefore m\angle A= (6\times 8- 18)\degree \\

\therefore m\angle A= (48- 18)\degree \\

\huge \purple {\boxed {\therefore m\angle A= 30\degree}} \\[/tex]

Answer:

x+y=7

y= x+3

Step-by-step explanation:

i just took the test

The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The sum of x and y is 7. The value of y is three more than the value of x. Then the equation is given as,

x + y = 7                ...1

y = x + 3               ...2

From equations 1 and 2, then we have

x + x + 3 = 7

2x = 4

x = 2

Then the value of the variable 'y' will be given as,

y = 2 + 3

y = 5

The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).

Answer:

11/8 or, 1 and 3/8

Step-by-step explanation:

First, we have to make both the denominators the same. In this case, we can multiply 3/4 by 2, to make 4, the denominator, into 8. What we do to the denominator, we must do to the numerator! So, we multiply 3 by 2, and get 6!

Now we have, 5/8 + 6/8, which equals 11/8! Which can also be simplified to 1 and 3/8 (because the numerator is larger than the denominator)

Hope this helps! :)

Answer:

[tex]Total = 7\frac{1}{2} cups[/tex]

Step-by-step explanation:

Given

Initially, he drank 3 pints of water

Then, [tex]1\frac{1}{2}[/tex] more cups

Required

How many cups did Ian drink altogether

This question can be solved by adding the size of water he drank during the hike and when he got home

i.e.

[tex]Total = 3\ pints + 1\frac{1}{2} cups[/tex]

But the answer should be in cups;

So, number of pints has to be converted to number cups

Given that 1 pint = 2 cups;

3 pints will be 3 * 2 cups

3 pints = 6 cups;

So,

[tex]Total = 3\ pints + 1\frac{1}{2} cups[/tex]

[tex]Total = 6\ cups + 1\frac{1}{2} cups[/tex]

[tex]Total = 7\frac{1}{2} cups[/tex]

Altogether, he drank [tex]7\frac{1}{2} cups[/tex] of water

Answer:

976cm^2

Step-by-step explanation:

Surface area:

Ara of cross section x 2 = 1/2 x 2 x 14 x 24 = 14 x 24 = 336

Area of base = 14 x 10 = 140

area of slope x 2 = 25 x 10 x 2 = 500

Total surface area = 500+140+336 = 640 + 336 = 973cm^2

Answer:

976 cm^2

Step-by-step explanation:

Area of triangle: 1/2bh

Area of rectangle b×h

2 Triangular ends 12×14=168 each So 336

2 sides 10×25=250 each So 500

1 base 10×14=140

Add: 140+500+336=976 square centimeters

Answer:

The answer is D on egdge2020

Answer:

r = 8

Step-by-step explanation:

15 = 1.5r+3

Subtract both sides of the equation by 3.

15-3 = 1.5r+3-3

12 = 1.5r

Divide both sides of the equation by 1.5.

12/1.5=1.5r/1.5

8 = r

r = 8

Answer:

[tex]8[/tex]

[tex]1.5r + 3 = 15 \\ 1.5r = 15 - 3 \\ 1.5r = 12 \\ r = \frac{12}{1.5} \\ r = \frac{120}{15} \\ r = 8[/tex]

Answer:

x = 55 degrees

Step-by-step explanation:

Angles of a triangle add up to 180 degree so we'll simply subtract the rest of the angles from 180 to get the value of x.

=> x = 180-75-50

=> x = 55 degrees

Answer:

55

Step-by-step explanation:

The sum of angles triangles will always be 180

75 + 50 is 135

180-35 = 55

B) II and III only

Step-by-step explanation:

Coordinates of A = (-1,0)

Coordinates of P =(4,12)

Let (x,y) be the coordinates of B

Distance formula : =[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

II) II and III only

Answer:

The order doesn’t matter, as the two events are probabilistically independent of one another. There are 13 spades in a standard 52 card deck, so the probability of drawing  the number 5 is 13/52 or 1/4. The probability of heads is 1/2. The probability of both occurring is the product of the two probabilities, or 1/4*1/2 = 1/8 or 12.5%.

Answer:

the probability of getting 5 from standard deck is 4/52 and probability to get tails from a flipped coin is 1/2

Step-by-step explanation:

as there are 4 parts in card i.e spade diamonds hearts and clubs which has 13 cards each from each 13 cards there are one 5 card so there are 4 cards with 5 number in standard deck

there is only one tails in a coin

Answer: she is 215m from her starting point

Step-by-step explanation:

The diagram representing the situation is shown in the attached photo. Triangle ABC is formed with AC representing her distance from her starting point.

Angle B = 28 + 90 = 118°

To determine AC, we would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and B is the angle corresponding to b(AC). Likening the expression to the given triangle, it becomes

AC² = AB² + BC² - 2(AB × BC)CosAC

AC² = 60² + 180² - 2(60 × 180)Cos118

AC² = 3600 + 32400 - 21600Cos118

AC² = 36000 - 21600(-0.46947156)

AC² = 36000 + 10140.59

AC² = 46140.59

AC = √46140.59

AC = 215 m

Answer: Option B.

Step-by-step explanation:

The price per ounce can be calculated as the amount of you paid divided the number of ounces that you get.

A) we have a table:

ounces          price

18                     $1.5

36                    $3.00

54                    $4.5

We can see that here we have a linear relationship. for example, the price for 18 ounces is $1.5

Then the price per ounce is:

p = $1.5/18 = $0.083

B) here we know that 15 oz cost $0.75, the price per ounce is:

p = $0.75/15 = $0.05

C) here we have 11 ounces, and the price is $2.20

then we have:

p = $2.2/11 = $0.2

Then we can conclude that the least expensive is option B.
