Answer:

£13.5

£40.5

Step-by-step explanation:

Let the amount of shares be x and 3x

Therefore,

x + 3x = 54 \\  \\ 4x = 54 \\  \\ x =  \frac{54}{4}  \\  \\ x = 13.5 \\  \\ 3x = 3 \times 13.5 = 40.5

The highway mileage m in miles per gallon for a compact car is approximated by m(s) = -0.025s^2 + 2.45s - 30, where s is the spe
Over [174]
The maximum mileage per gallon for the compact car is determined by taking the first derivative of the given equation and equate to zero. The differentiated form is m's = -0.05 s + 2.45 = 0; s is equal to 49 seconds. substituting this s, m is equal to 30.025 miles/gallon.

Draw a figure strategy a snail is at t bottom of a 10 ft wall. Each day it climbs up 3 ft. Each night it slides down back 1 ft.
antiseptic1488 [7]
The snail will reach the top of the wall by day 5.

(3ft-1ft)x = 10ft
2x = 10
2x / 2 = 10/2
x = 5 days.

The snail will reach the top of the wall on the 5th day.

11=                                                 d5
10=                                                        d5
9=                                       d4
8=                                             d4  d5
7=                          d3
6=                                d3  d4
5=             d2
4=                  d2    d3
3=  d1

Answer:

There is a 100% probability that the selected tick is also a carrier of Lyme disease.

Step-by-step explanation:

The problem states that:

Of the ticks that carry at least one of these diseases in fact carry both of them.

So, if a tick carries one of these diseases, there is a 100% probability that is carries another.

What is the probability that the selected tick is also a carrier of Lyme disease?

There is a 100% probability that the selected tick is also a carrier of Lyme disease.

Write the equation in slope-intercept form through the point (-5, 3) and is perpendicular to the line y = 2x - 3 and graph​
xxTIMURxx [149]

Slope intercept form: y = mx + b

When a line is perpendicular to another line, its slope is the negative reciprocal to that slope.

From this information, we already know that the slope of our new line is -1/2, because -1/2 is the negative reciprocal to 2 (which is the slope of the original line).

y = -1/2x + b

Because the point (-5,3) is given, we can simply plug the x and y coordinates into our incomplete equation.

3 = -1/2(-5) + b

3=2.5 + b

b = 0.5

ANSWER: y = -1/2x + 0.5

THE GRAPH IS LINKED; RED LINE IS y=2x-3 AND BLUE LINE IS y=-1/2x + 0.5
