Simplify using suitable properties 2/5 × 7/6 + 7/6 × 7/2​

Mathematics
1 answer:
natta225 [31]3 years ago
3 0

Answer:

4 11/20

Step-by-step explanation:

Using bidMAs Multiplication comes first before addition

2/5 * 7/6 = 14/30

7/6 * 7/2 = 49/12

Make denominators equal

14/30 * 2 = 28/60

49/12 * 5 = 245/60

Then add

28/60 + 245/60 = 273/60

Finally convert improper into mixed fraction

4 11/20

The table represents the cost of flowers at the Tigerlily Flower Shop.
Afina-wow [57]

Answer:

The given table is

Quantity(x)     Price(y)

   1                  2.00

   2                 3.50

   3                 5.00

   4                 6.50

   5                 8.00

   6                 9.00

It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).

The graph 1 represents all the above mentioned point, therefore option 1 is correct.

According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.

The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.

Therefore the option 3 and 4 are incorrect.

While flipping a weighted coin, Latrell gets 4 heads and 2 tails. Based on experimental probability, how many of the next 3 flip
zaharov [31]

Answer:  2 heads

Step-by-step explanation:

First, write the experimental probability as a fraction in simplest form.

P(heads)

=

heads

total

=

heads

heads+tails

=

4

4+2

=

4

6

=

2

3

The experimental probability is

2

3

.

We can predict the outcome of the second set of trials by assuming that the ratio will be the same as in the first set of trials. Write a proportion by setting the two ratios equal to each other, then solve.

2

3

=

n

3

2

3

(33)

=

n

3

(33) Multiply both sides by (33)

23

= 3n Simplify

6

= 3n Simplify

2

= n Divide both sides by 3

Based on experimental probability, Latrell should expect 2 of the next 3 flips to come up heads.

Investors buy a studio apartment for $150,000. Of this amount, they have a down payment of $22,500. Their down payment is what p
Dafna11 [192]
(N stands for the number)So we do a simple problem:
$150,000 - N% = $67,500
$150,000 - 45% = $67,500
$67,500 is 45% of $150,000
Down payment answer:
$150,000 - N% = $22,500
$150,000 - 15% = 22,500
$22,500 is 15% of $150,000
