A tree is 58 inches tall. how tall is it in feet and inches
mart [117]
A foot is 12 inches.
12 can go into 58 evenly 4 times, since 12• 4 equals 48 but 12 • 5 equals 60. This means that the tree is at least 4 feet. Then to find the leftover inches we do 58-48 equals 10, therefore the answer is 58 inches translates to 4 feet and 10 inches.

The lakers scored a total of 80 points in a basketball game against the bulls. the lakers made a total of 37 two-point and three
11111nata11111 [884]
<span>The answer is 2 three-point shots. Since the Lakers made 37 two-point shots, one multiplies 37 by 2 (37 x 2), which equals 74. Then 74 is subtracted from the total 80 to see how many points are left (80 - 74), which equals 6. To determine the number of three-point shots, 6 is divided by 3 (6/3), which equals 2.</span>

Gabriela Mistral was a poet, diplomat, teacher and humanitarian. Each week she worked a certain amount of days as a poet diploma
Ipatiy [6.2K]

Answer:

Gabriela Mistral works as a humanitarian for 8 days.

Step-by-step explanation:

Gabriela Mistral was a poet, diplomat, teacher and humanitarian such that each week she worked a certain amount of days as a poet diplomat teacher and humanitarian.

Ratio is 1:1:3:2

Let x denotes total number of days Gabriela Mistral work.

As she works 12 days as a teacher,

\frac{3}{7}x=12\\ x=\frac{7}{3}(12)\\ x=28

Total number of days =x=28

So,

she works as a humanitarian for \frac{2}{7}x=\frac{2}{7}(28)=8 days.

Show all work to solve by factoring 3x^2 − x − 2 = 0.
shtirl [24]

Answer:

The solutions are x=1 and x=-2/3

Step-by-step explanation:

we have

3x^{2}-x-2=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

3x^{2}-x=2

Factor the leading coefficient

3(x^{2}-(1/3)x)=2

Complete the square. Remember to balance the equation by adding the same constants to each side

3(x^{2}-(1/3)x+(1/36))=2+(1/12)

3(x^{2}-(1/3)x+(1/36))=25/12

Rewrite as perfect squares

3(x-(1/6))^{2}=25/12

(x-(1/6))^{2}=25/36

square root both sides

(x-(1/6))=(+/-)(5/6)

x=(1/6)(+/-)(5/6)

x=(1/6)(+)(5/6)=1

x=(1/6)(-)(5/6)=-2/3
