Mathematics
1 answer:
Illusion [34]2 years ago
7 0

Answer:

100

Step-by-step explanation:

10(-2.5) = -25 since negative times positive is negative.

-25(-4)=100 since negative times negative is positive.

Basically, the negative inverts the sign so a negative negates a positive yielding a negative while a negative negates a negative yielding a positive.

Think of it as not not vs not

Jazmin takes a ride share service home from the airport. The ride share service charges $5 as an initial cost to pick her up, an
Anon25 [30]

Answer:

38.75 = 2.25 m + 5

Step-by-step explanation:

It is given that :

Jazmin took a ride share service from airport to home.

The total cost of the ride service from airport to home is = $ 38.75

The ride service charged an initial cost for picker Jazmin = $ 5

Cost of the ride service for every mile = $ 2.25 per mile

Let the number of miles = m

Therefore, the equation that represents the situation is :

38.75 = 2.25 m + 5

where, m represents the number of miles.

\sin(60°) =  \frac{x}{14}  \Leftrightarrow x = 14 \sin(60°) =  \frac{14 \sqrt{3} }{2}  = 7 \sqrt{3}  \\  \cos(60°)  =  \frac{y}{14} \Leftrightarrow y = 14\cos(60°) =  \frac{14}{2}  = 7

In the figure to the right, AB = 7 1/2 m, BC = 2 1/4 m, and DE = 1 1/4 m. Find the perimeter of the figure if all angles are rig
Andreas93 [3]

Answer:

Perimeter=22 m

Step-by-step explanation:

Perimeter Of A Figure

Perimeter is the distance measured around a shape. If the figure is line-shaped, the perimeter can be obtained by adding the individual lengths of each segment around the shape.

The figure shown is surrounded by line segments. We only have to add them all to find the perimeter. But we don't need each individual length to do so. We may notice the following (given all angles are right):

The sum of HG+FE+DC equals AB. So the upper and lower lengths are twice AB, or equivalently: 2*7 1/2 m =15 m

It can also be noted that AH+GF=BC+DE=2 1/4+1 1/4 = 3 1/2 m. It means that the two lateral lengths are twice this value: 2* 3 1/2 = 7 m

Thus, the total perimeter is 15 m + 7 m = 22 m
