Answer Mr. Gerard speed was at most 25 miles per hour before the curve

Step-by-step explanation:

How to solve the speed Mr. Gerard was driving before the curve

Let’s just assume that Gerard went exactly the speed limit 15 miles per hour (mph) after when he slowed down by 10 miles per hour and drove around the curve. The reason why I’m using exactly 15mph is because it’s the max speed he can go. He can go 15 miles per hour and still be safe, but it’s just that he can’t go any faster than that.

Now, you can do 15 + 10 to find the speed he went before he drove around the curve. So, that would be 25mph before he drove around the curve.

You might be asking: What if he went slower than 25mph before he drove around the curve, and what if he went faster than 25mph?

-When he drives exactly 25mph and slows down by 10mph when he makes the turn around the curve, he’s going exactly 15mph which it safe for him because it’s not faster than 15mph.

-It could be possible that he went slower than 25mph before he drove around the curve, but he still will be safe because when he makes the turn around the curve and slows down by 10 miles per hour, now he’ll reach below 15 miles per hour which is even safer for him. Here’s an example for you to understand: Let’s say he drove 23mph before the curve (which is less than 25mph). As soon as he makes the turn around the curve, he slows down by 10mph. So after he goes around the curve, he’s going 13mph, which is less than the speed limit 15mph. You can take any number less than 25mph and he’ll still be safe because it will be less than 15mph.

-Now, if he went faster than 25mph, he wouldn’t be safe anymore because after when he slows down by 10mph and goes around the curve, he’ll be above the speed limit of 15mph. Here’s an example for you to understand: Let’s say he drove 27mph before the curve (which is faster than 25mph). As soon as he makes the turn around the curve, he slows down by 10mph. So after he goes around the curve, he’s going 17mph, which is faster than the speed limit 15mph.

Answer: Mr. Gerard speed was at most 25 miles per hour before the curve

Graphing it

A way to graph this is to write out a compound inequality. You can write it as:

0 < y ≤ 25  ⇒ Where any speed has to be less than or equal to 25 miles per hour, because 25 miles per hour is the most/biggest speed Mr. Gerard can drive. But it has to be greater than 0 because you can’t go negative miles per hour, or 0 miles per hour

The graph is shown below ↓

I don’t know what graph you want, or how your teacher wants you to graph it. So I put two options for you :)

I hope you understand and that this helps with your question! :)

4.5m is 500% of 90cm

90cm is 20% of 4.5m.

Step-by-step explanation:

by trigonometry,

cos 30 = x/12√3 =√3/2

→ x=18

sin 30 =y/12√3=1/2

→ y=6√3

The values of x and y are 18 and 10.392 respectively.

The definition for a right triangle states that if one of the angles of a triangle is a right angle - 90º, the triangle is called a right-angled triangle or simply, a right triangle. In the given image, triangle ABC is a right triangle, where we have the base, the altitude, and the hypotenuse. Here AB is the base, AC is the altitude, and BC is the hypotenuse.

Given right triangle

hypotenuse = 12√3

base = x and height  = y

angle of base  = 30°

cosФ = b/h

cos30 = x/12√3

x = 12√3 x √3/2

x = 18

and sin30 = p/h

sin 30 = p/12√3

p = 1/2 x 12√3

p = 6√3

p = 10.392

Hence the values of x= 18 and y = 10.392.

Answer:

63 chickens per square mile

Step-by-step explanation:

We are to calculate the average number of chickens per square mile.

Number of chickens = 40×5⁷

Number of square miles = 16×5⁵

The average number of chickens per square mile = 40 × 5⁷/16 × 5⁵

= 3125000/50000

= 62.5 chickens per square mile

Approximately to the nearest whole number is

= 63 chickens per square mile

Therefore,the average number of chickens per square mile is 63 chickens per square mile.

Answer: 409.6

Step-by-step explanation:

Let the total number of sixth grade students be represented by x.

We are further told that 5/8 of the sixth grade students at clearview middle school buy their lunch which was about 256 students. We can represent this into an equation as:

5/8 × x = 256

0.625x = 256

x = 256/0.625

Answer:

place a point at (0, 4) and (-4, 0) and draw a line through them

Step-by-step explanation:

to graph something, place a point at the slope intercepts.

to find the y intercept, set x to 0

y = 0 + 4

y = 4

the y intercept is 4, or (0, 4)

to find the x intercept, set y to 0

0 = x + 4

0 - 4 = x + 4 - 4

0 - 4 = x

-4 = x

the x intercept is -4 or (-4, 0)

Answer:

O1

Step-by-step explanation:

Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.

We are given a point: (0,-2) and a slope; -3.

we can substitute the numbers into the equation above, with what we know, to find b.

-2=-3(0)+b

multiply

-2=0+b

-2=b

so the y intercept is -2.

Since we know that the slope is -3, and the y intercept is -2, the equation is y=-3x-2

Therefore O1 is your answer

Answer:

4 and 4/15=c. 2 and 2/15=p.

Step-by-step explanation:

I am younger than 12 i dont have much experience; done 2 or 3 problems like this...

first lets make it simpler...

2c+4p=11.20 is the same as c+2p=5.6

then subtract one from the other and you get 4c+2p=12.8

simplify again 2c+p=6.4

so the ratio of c to p is 2:1. Multiply 6.4 by 2/3 to get what c is... 64/15

64/15 is 4 and 4/15. then divide by 2 to get what p is so 64/15÷2=32/15 which is 2 and 2/15.

$800.36

Step-by-step explanation:

429+289=748

7% of 748= 52.36

748 + 52.36=800.36

The total price of the dishwasher and microwave after the sales tax of 7% will be $800.36.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Jill is buying new appliances.

The cost of the dishwasher is $459 and the cost of the microwave is $289.

The total amount of the dishwasher and microwave will be

Total amount = 459 + 289

Total amount = $748

Then the price of the dishwasher and microwave after the sales tax of 7% will be

Total price = 7% of $748

Total price = 1.07 x $748

Total price = $800.36

Then the total price of the dishwasher and microwave after the sales tax of 7% will be $800.36.
