Answer:

Area of first shape is 288[tex]ft^{2}[/tex], area of second shape is 45[tex]m^{2}[/tex], area of third shape is 34[tex]in^{2}[/tex].

Step-by-step explanation:

Area of first shape

A=bh

A=18*16

A=288

Second shape

A=bh

A=9*5

A=45

Third shape

A= 1/2 h(b1+b2)

A=1/24(12+5)

A=1/2*4(12+5)

A=1/2*4(17)

Answer:

1/8 chance

Step-by-step explanation:

You have 1/2 chance of getting tails

You have 1/4 chance of spinning B

1/2 * 1/4 = 1/8

Answer:

1/8

Step-by-step explanation:

When we're looking for the probability of one event and another event to occur together, we multiply their probabilities. Here, the probability of flipping a tails is 1/2, and the probability of spinning a B is 1/4, so the probability that we flip a tails and spin a B is 1/2 · 1/4 = 1/8.

The sum of two numbers is 46. The larger number is two less than three times the smaller number. Find the numbers?

Answers

Let x and y be the two numbers.

x + y = 46

x = 3y - 2

Put value of x from equation 2nd to 1st

4y - 2 = 46

y = 48/4 = 12

x =3*12 - 2 = 34

So, the two numbers are (34,12)

A pair of boots has an original price of $95. They are on sale for 35 percent off. What number can you multiply $95 by to equal the discounted price of $61.75?
A.0.35
B.0.60
C.0.65
D.0.95

Answers

Answer: C- 0.65

Step-by-step explanation:

Answer:
0.65
Step-by-step explanation:
We are given that,
Original cost of the pair of boots = $95
Also, the boots are 35% off.
Since, the discount is 35% of the total amount.
The remaining amount to be paid = 100 - 35 = 65% of the total amount.
Thus, the discounted price = 65% of the total amount
i.e. The discounted price = 65% × $95 = 0.65 × $95 = $61.75
Hence, we need to multiply 0.65 to $95 to get the discounted price of $61.75.
