Fatimah,Siti and Noraini share 90 marbles in the ratio 4 : 5 : 6.Calculate the number of marbles that siti receives.

USPshnik [31]

Answer:

30 marbles.

Step-by-step explanation:

Let Fatimah,Siti and Noraini has 4x, 5x and 6x marbles.

$\therefore \: 4x + 5x + 6x = 90 \\ \therefore \: 15x = 90 \\ \therefore \: x = \frac{90}{15} \\ \therefore \: x = 6 \\ 5x = 5 \times 6 = 30$

Hence, Siti received 30 marbles.

(1) What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of negative 5/6 (all fractio

Andreyy89

Formula for point-slope: $y - y1 = m(x-x1)$
Plug in the values (1): $y + 4 = -\frac{5}{6} (x - 8)$ {Choice B}
Plug in the values (2): $y + 6 = \frac{1}{3}(x+ 2)$ {Choice C}
_______________________

[For (3) and (4) we need to solve for slope]

(3)
First, solve for slope.
Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in values: $\frac{-1-5}{-4-7} = - \frac{6}{11}$
Slope: $- \frac{6}{11}$
Second, we must plug into point-slope form.
Formula for point-slope: $y - y1 = m(x-x1)$
Plug in the values: $y + 1 = - \frac{6}{11}(x + 4)$ {Choice C}

(4)
First, solve for slope.
Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in values: $\frac{6-(-8)}{-4-7} = - \frac{14}{11}$
Slope: $- \frac{14}{11}$
Second, we must plug into point-slope form.
Formula for point-slope: $y - y1 = m(x-x1)$
Plug in the values: $y - 6 = - \frac{14}{11}(x + 4)$ {Choice D}

Convert 4 radians to degrees.

Sveta_85 [38]

Hello!

To convert radians to degrees, we have to multiply them by $180/ \pi$ .
Let's multiply.
$4*180/ \pi$
≈ 229.18311805

Please note that since we are using $\pi$ , we need to use the approximation sign.

4 radians ≈ 229.18311805°

You can feel free to let me know if you have any questions regarding this!
Thanks!
