Answer:

-36,047.

Step-by-step explanation:

Sum of n terms = a1 .( r^n - 1) / (r - 1)

So Sum of 7 terms = -11 . ((-4)^7 - 1 / (-4-1)

= -11 * -16,385 / -5

= -36,047.

The equation of a line for the given slope is $y=\frac{1}{2} x+1$ .

Solution:

Given data:

Slope (m) = $\frac{1}{2}$

Point = (–2, 0)

$x_1=-2, y_1=0$

To find the equation of the given line in the point-slope form:

<u>Point-slope formula:</u>

$y-y_1=m(x-x_1)$

Substitute the given values in the formula.

$$y-0=\frac{1}{2} (x-(-2))$

$$y=\frac{1}{2} (x+2)$

$$y=\frac{1}{2} x+\frac{2}{2}$

$$y=\frac{1}{2} x+1$

The equation of a line for the given slope is $y=\frac{1}{2} x+1$ .

Question 3

Crank

Step-by-step explanation:

Given that,

The mass of a patient = 70 kg

A 70kg patient has approximately 8 pints of blood.

The patient donates 470mL of blood.

We know that,

1 pint = 568 mL

8 pints = 4544 mL

Required fraction,

$\dfrac{470}{4544}=0.1\\\\=\dfrac{1}{10}$

So, the required fraction is approximately $\dfrac{1}{10}$ .

Gabriela walked to school on 16 of the 24 school days in March. Which value is equivalent to the fraction of the school days in

olchik [2.2K]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.

The numerator is the number above. While the denominator is the number below

an example of a fraction = $\frac{4}{5}$

4 is the numerator while 5 is the denominator

In this question, the numerator would be the number of times she walked to school in march(16). While the denominator would be the number of school days in March

$\frac{16}{24}$

the above fraction is not in its simplest form. To express in its simplest form, divide both numerator and the denominator by 8 . this gives

$\frac{2}{3}$
