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:

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]

AP = BP

[tex]\sqrt{(4+1)^2+(12-0)^2}=\sqrt{(4-x)^2+(12-y)^2}[/tex]

[tex](4+1)^2+(12-0)^2=(4-x)^2+(12-y)^2[/tex]

[tex]169=16+x^2-8x+144+y^2-24y[/tex]

[tex]x^2-8x+y^2-24y-9=0[/tex]

I)(3/2,6)

[tex](\frac{3}{2})^2-8(\frac{3}{2})+6^2-24(6)-9=0\\-126.75 \neq 0[/tex]

II)(9,24)

[tex](9)^2-8(9)+(24)^2-24(24)-9=0[/tex]

0= 0

C)(-8,7)

[tex](-8)^2-8(-8)+(7)^2-24(7)-9=0[/tex]

0=0

So, II and III could be the coordinates of B

So Option B is true

II) II and III only

Answer:

a) x = 5

b) x = 12

Step-by-step explanation:

x + 3 = 8

Subtract 3 on both sides.

x = 8 - 3

x = 5

x - 5 = 7

Add 5 on both sides.

x = 7 + 5

x = 12

Answer:

[tex]a)x = 5 \\ b)x = 12[/tex]

Step-by-step explanation:

[tex]a)x + 3 = 8 \\ x = 8 - 3 \\ x = 5[/tex]

[tex]b)x - 5 = 7 \\ x = 7 + 5 \\ x = 12[/tex]

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:

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: 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.

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

Answer:  A. Drawing a jack and drawing a six without replacement

Step-by-step explanation:

A Dependent event means the outcome of one event affects the outcome of the other event.

Options B, C, and D:

The first event is completely unrelated to the second event so those options are Independent events.

Option A:

The first event uses 52 cards.  The second event only has 51 cards remaining because we did not replace the first card.  The probability of the second event IS affected by the first event so this is a Dependent event.

Note: If the card was replaced before drawing the second card, then it would be an Independent event.

The example for dependent events is (A) Drawing a jack from a standard deck of cards and then drawing a six without replacing the jack.

If the probability of one event of two events is affected by another one then that two events are called dependent events of one another.

The probability of an event is the ratio of the favorable cases for that event to the total number of possible cases under that event.

Here analyzing the given choices we get,

(A) If we draw a jack from a standard deck of cards that is containing 52 cards.

And then we draw a six replacing without that jack card then it affects the probability as the total number of cards for this event reduces from 52 to 51.

So these two events are dependent events.

(B) Winning a lottery and getting struck by lighting are completely two different events from a different field, so they are independent.

(C) Spinning a 5 on a spinner cannot affect getting tails from flipping a coin. So they are not dependent on events.

(D) Owning a dog cannot affect being in the school chorus so they are independent (not dependent).

Hence the correct answer is (A).

Answer:

If angle 2 = 110 then angle 4 = 110

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
