Answer:

Step-by-step explanation:

Step 1: Find the total fraction of raisins he gave to his brothers

Step 2: Find the lowest common multiple(Lcm) of 6 and 4

Lcm of 6 and 4 = 12

Step 3: Add the fractions

= $\frac{2+ 3}{12}$

= $\frac{5}{12}$

Step 4: To find the fraction that he kept, you will subtract the total fractions he gave his brothers from 1.

$1 - \frac{5}{12} \\= \frac{12-5}{12} \\= \frac{7}{12}$

Final answer

The fraction that he kept = $\frac{7}{12}$

student found the slope of a line that passes through the points (1, 14)and (3, 4) to be 5. What mistake did she make?

vladimir2022 [97]

Y2-y1/x2-x1
(1,14) & (3,4)
y2= 4
y1=14
x2=3
x1=1

So....

(4-14)/(3-1) = -10/2 = -5

The answer should be negative instead of positive, she probably subtracted 4 from 14 instead.

If r= 1 and 0=3.14/4, what is the approximate arc length?

baherus [9]

The approximate arc length from the task content is; Choice C; 0.785 units.

<h3>What is the approximate arc length?</h3>

Since the arc length is given mathematically by the formular;

Arc length = (A/360) × 2πr

Hence, since A = π/4 = 18/4 = 45.

Hence; Arc Length = (45/360) × 2 × 3.14 ×1

Arc length = 6.28/8 = 0.785 units.

PLEASE HELP!! Is the answer 50 seconds???

saw5 [17]

Answer:

Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> altitude in meters

we have

$g(x)=\frac{1}{20}x(x-100)$

$g(x)=\frac{1}{20}x^{2}-5x$

This is a vertical parabola open upward

The vertex is a minimum

To find out the lowest altitude, find the vertex

Complete the square

Factor the leading coefficient

$g(x)=\frac{1}{20}(x^{2}-100x)$

$g(x)+125=\frac{1}{20}(x^{2}-100x+2,500)$

Rewrite as perfect square

$g(x)+125=\frac{1}{20}(x-50)^{2}$

$g(x)=\frac{1}{20}(x-50)^{2}-125$

The vertex is the point (50,-125)

therefore

Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m (below the sea level)
