1 ) Multiply the largest number (10) by 1.

Can the smallest (4) go into this number evenly?

10 x 1 = 10

10/4 = 2.5 ❌

2 ) Now multiply the largest number by 2.

Can the smallest go into this number evenly?

10 x 2 = 20

20/4 = 5 ✅

The LCD is 20

Answer:

x = 63.7°

Step-by-step explanation:

Since the triangle is right we can use trig. ratios to solve

tan x° = $\frac{opposite}{adjacent}$ = $\frac{14.6}{7.2}$

⇒ x = $tan^{-1}$ ( $\frac{14.6}{7.2}$ ) = 63.7°

Susan has a collection of 65 nickels and dimes. If the number of nickels is four times the number of dimes, how many nickels and

NikAS [45]

Answer:

d = 13 and n = 52

Step-by-step explanation:

Number of dimes: d

Number of nickels: n

Then d + n = 65, and n = 4d

Substituting 4d for n in the first equation, we get:

d + 4d = 65, or 5d = 65. Then d = 13 and n = 52

First, I'm going to separate factor the expression inside of the square root.

sqrt[ (2/18) * (x^5) ]

sqrt[ (1/9) * (x^5) ]

We can take the square root of 1/9 easily, because 1 and 9 are both perfect squares. The square root of 1/9 is 1/3.

Looking at the x^5, we can separate it into x^2 * x^2 * x^1. The square root of x^2 is x. So, we now also have an x^2 on the outside because there are two x^2s in our expanded form.

ANSWER: (x^2 * sqrt(x)) / 3

(Option 1)

Hope this helps!

before school began mrs. weeks bought a total of 86 balls us the information below to help you write a numerical expression

STALIN [3.7K]

For this case we have that the total of the balls is 86. We know there are 8 footballs then:

Basketball: Two more than twice the number of footballs are basketballs, that is:

$2 + 2 (8) = 2 + 16 = 18$

There are 18 Basketballs.

Baseballs: Four less than 5 times the number of footballs are baseballs, that is:

$5 (8) -4 = 40-4 = 36$

There are 36 Baseballs.

Softballs: Six more than half of baseballs are softballs. That is to say:

$6+ \frac {36} {2} = 6 + 18 = 24$

There are 24 Softballs

If we add we must get 86.

$8 + 18 + 36 + 24 = 86$

ANswer:

There are 8 Footballs

There are 18 Basketballs.

There are 36 Baseballs.

There are 24 Softballs
