Answer:

60

Step-by-step explanation:

The ratio of sizes is ...

blood cell / bacteria = 9×10^-6/(1.5×10^-7) = 90×10^-7/(1.5×10^-7)

= 90/1.5 = 60

The red blood cell's length is 60 times that of the bacteria.

Write the equation of the line parallel to the

kakasveta [241]

Answer:

x=-7

Step-by-step explanation:

If a line is parallel to the y-axis, then it is vertical because the y-axis is vertical.

A vertical line is in the form of x=a number.

Since the line we are looking for is 7 units to the left of the y-axis, then the line is x=-7. -7 is 7 units left of 0.

7 units right would have been x=7.

M=1/5 y-intercept is 0,4

ValentinkaMS [17]

Answer:

y = $\frac{1}{5}$ x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{1}{5}$ and c = 4, thus

y = $\frac{1}{5}$ x + 4 ← equation of line

Doug bought a new car for $25,000. He estimates his car will depreciate, or lose value, at a rate of 20% per year. The value of

strojnjashka [21]

Answer:

Step-by-step explanation:

The equation actually looks like this

$V=P(1-r)^t$ and filling in the info given:

$V=25,000(1-.2)^{4.5$ which simplifies to

$V=25,000(.8)^{4.5$

Orders of operation tells us that we need to take care of the exponential stuff first, so

V = 25,000(.3663573) and

V = $9158.93 which rounds to what is shown as the second choice down: $9,159.

Answer these In scientific notation with work shown, adding scientific notation.

vichka [17]

Answer:

1. $9.9 \times 10^{-1} + 5.2 \times 10^{-2} = 104.2 \times 10^{-2}$

2. $3.24 \times 10^{5} + 8.3 \times 10^{1} =32408.3 \times 10^{1}$

3. $1.24 \times 10^{0} + 5 \times 10^{-1} = 13.64 \times 10^{-1}$

Step-by-step explanation:

1) $9.9 \times 10^{-1} + 5.2 \times 10^{-2}$

Now, $9.9 \times 10^{-1}$ = $99 \times 10^{-2}$

So, $99 \times 10^{-2} + 5.2 \times 10^{-2}$ = $104.2 \times 10^{-2}$

2. $3.24 \times 10^{5} + 8.3 \times 10^{1}$

Now, $3.24 \times 10^{5}$ = $32400 \times 10^{1}$

So, $32400 \times 10^{1} + 8.3 \times 10^{1}$ = $32408.3 \times 10^{1}$

3. $1.24 \times 10^{0} + 5 \times 10^{-1}$

Now, $1.24 \times 10^{0}$ = $12.4 \times 10^{1-}$

So, $1.24 \times 10^{0} + 12.4 \times 10^{1-}$ = $13.64 \times 10^{-1}$
