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

SOLVE APPLICATION USING ALGEBRA. TYPE THE EQUATION OR INEQUALITY AND PLEASE SHOW WORK. a) A rectangle with perimeter 18 cm has length that is 3 cm more than twice its width. Find the dimensions of the rectangle.
Answer:
[tex]w=2\\l=7[/tex]
Step-by-step explanation:
[tex]l+l+w+w=18\\\\2w+3=l\\\\2w+3+2w+3+w+w=18\\6w+6=18\\6w=12\\w=2\\\\2w+3=l\\2*2+3=l\\4+3=l\\l=7[/tex]
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
Segments AP and BP have the same length. If the coordinates of A and P are (-1,0) and (4,12), respectively, which could be the coordinates of B?
I. (3/2, 6)
II. (9, 24)
III. (-8,7)
A) I and II only
B) II and III only
C) II only
D) III only
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

A card is drawn at random from a standard pack of playing cards. Then a fair coin is flipped. What is the probability of selecting a 5 and the coin landing on tails?
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

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 = 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 \\

Which expressions are equal to 0 when x=-1? Check all that apply.
4(x+1)/(4x+5)
4(x-1)/(5-4x)
4(x-(-1))/(4x+5)
4(x+(-1))/(4x+5)
4(x+1)/(5-4x)
Answer:
4(x+1)/(4x+5)
4(x+1)/(5-4x)
4(x-(-1))/(4x+5)
Step-by-step explanation:
The numerators in the fractions must equal to 0, or else the expressions won’t have the result of 0.
4(x+1)
4(-1+1)
4(0)
= 0
4(x-(-1))
4(-1-(-1))
4(-1+1)
4(0)

D. 4 (x + (-1))/(4x + 5) = 4 (-1 - 1)/(4 × -1 + 5) = 8
E. 4 (x + 1)/(5 - 4x) = 4 (-1 + 1)/(5 - 4 × -1) = 0
The expressions are equal to 0 when x = -1 will be 4(x+1)/(4x+5), 4(x-(-1))/(4x+5), and 4(x+1)/(5-4x).

select a brand with the least expensive corn per ounce
A) ounces price
18 1.50
36 3.00
54 4.50
B) .75 for 15 oz
C) Maia buys an 11 ounce can of brand c corn for 2.20
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.

Step-by-step explanation:
Easiest and fastest way is to simply graph the equation and find what it's asking.
What are the asymptote and the Y intercept of the function shown in the graph f(x)=3(0.2)^x+2
the asymptote is y = 2 and the y - intercept is (0,5)
What is asymptote function?An asymptote is a line that the graph of a function approaches as either x or y go to positive or negative infinity. There are three types of asymptotes: vertical, horizontal and oblique. That is, as approaches from either the positive or negative side, the function approaches positive or negative infinity.
According to the question
The function reaches the y-axis at the point (0,5).
The asymptote is the line that the function follows but never quite reaches. In this case, the function follows the path of y = 2. However, it never exactly fits the line.
The y-intercept is (0,5) and the asymptote is y = 2. The answer, then, is B.
Hence, the asymptote is y = 2 and the y - intercept is (0,5)

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards without replacement from a standard deck. If both cards are spades, your friend will pay you $225. Otherwise, you have to pay your friend $12. Step 2 of 2 : If this same bet is made 738 times, how much would you expect to win or lose? Round your answer to two decimal places. Losses must be expressed as negative values.
Answer:
Win $1,423.59
Step-by-step explanation:
There are 52 cards in a deck, 13 of which are spades.
The probability if drawing two consecutive spades without replacement is:
[tex]P(W) = \frac{13}{52}*\frac{12}{51}\\ P(W) = \frac{3}{51}[/tex]
Therefore, there is a 3 in 51 chance of you winning $225 and a 48 in 51 chance of you losing $12.
The expected value for 738 games is:
[tex]E= 738(\frac{3}{51}*225-\frac{48}{51}*12)\\ E=\$1,423.59[/tex]
You are expected to win $1,423.59.

Answer: B. (-3, 3.25)
Step-by-step explanation: Imagine that the line is divided into 4 segments. (3:1) Since A is at the upper right end of the line, go 3 segments down and left from A. That puts the x value at -3.

Hi, to answer this question we simply have to substitute h=10 (height) in the formula given:
h=2.5w -5
Replacing:
10= 2.5w-5
Solving for w (width)
10+5=2.5w
15 =2.5w

Brian rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is prime. Answer THIS PLEASE I AM SO CONFUSED
Answer:
5/12 or 15/36
Step-by-step explanation:
Since he rolls two dice, he has a total probability of 6 times 6 = 36. The pairs, that he could add up to primes are (1,1), (2,1) * 2 (since he can get 1,2 as well), (1,4) * 2, (2,3) * 2, (3,4) * 2, (5, 2) * 2, (6,1) * 2, (5, 6) * 2. This is 1 + 2 + 2 + 2 + 2 + 2 + 2 + 2, which is equal to 15. This is a total of 15/36 possible ways, which is also equal to 5/12.
