Answer:

7 miles

Step-by-step explanation:

As, we will take unit rate as "x"

So, for one day = x distance

For 5 days = 5(x)

For 5 days she covered 35 miles

So therefore,

5(x) = 35 miles

X= 35/5

X=7 miles

For a day= 7 miles are covered

Answer:

45 words per minute

Step-by-step explanation:

60 / 1 [tex]\frac{1}{3}[/tex]

45

The average typing speed of Joseph in words per minute is 45 words per minute​.

The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.

Now it is given that,

Number of words = typed 60 words

Time taken = 1 and 1/3 minutes

⇒ Time taken = 4/3 minutes

Thus, Average typing speed = Number of words / Time taken

⇒ Average typing speed = 60 / (4/3) words per minute​

⇒ Average typing speed = 45 words per minute​

Thus, the average typing speed of Joseph in words per minute is 45 words per minute​.

Center = (5,7)

Radius = 5

======================================================

Explanation:

The circle must be tangent to the y axis, and it has a radius of 5, so that means the center (h,k) must either be on the line x = 5 or x = -5, since those vertical lines are exactly five units away from the y axis.

But we're also told that (10,7) must be on the circle. That rules out x = -5 because the distance from (10,7) to (-5,k) is going to be larger than 5. I recommend drawing out a right triangle to see why this is the case.

So the center (h,k) must be on the line x = 5.

The center is the point (h,k) = (5,k)

Plug that h value along with (x,y) = (10,7) and r = 5 into the equation below

Solve for k.

(x-h)^2 + (y-k)^2 = r^2

(x-5)^2 + (y-k)^2 = 5^2 .... plug in h = 5 and r = 5

(10-5)^2 + (7-k)^2 = 25 ... plug in x = 10 and y = 7

25 + (7-k)^2 = 25

(7-k)^2 = 25-25

(7-k)^2 = 0

7-k = sqrt(0)

7-k = 0

-k = 0-7

-k = -7

k = 7

The center is (h,k) = (5,7)

We have (x-h)^2 + (y-k)^2 = r^2 updating to (x-5)^2 + (y-7)^2 = 25

The equation of the circle is   (x-5)^2 + (y-7)^2 is25 .  The center of the circle is Center is (5,7) .Radius of the circle  is  5

Circle's basic equation is represented by:

(x-h)2 + (y-k)2 = r2

where the radius is r and the circle's center's coordinates are (h,k).

Let's first consider what a circle is before determining its equation. A circle is a collection of all points in a plane that are uniformly distanced from a fixed point. The fixed point is referred to as the circle's center. The radius of a circle is the separation between the center and any point along its circumference. In this article, we'll explain what a circle's equation looks like in standard form and show you how to calculate a circle's equation when its center is both the origin and another point.

The center (h,k) of the circle, which must be tangent to the y axis and have a radius of 5, must either be on the line x = 5 or x = -5 since both vertical lines are both located exactly five units from the y axis.

The need that (10,7) be on the circle is also stated, though. That eliminates the possibility of x = -5 because the distance from (10,7) to (-5,k) will be more than 5. To understand why this is the case, I advise you to sketch a right triangle.

Therefore, the line x = 5 must contain the center (h,k).

The point (h,k) = is the center (5,k)

Given ,

In the equation below, enter that h value along with (x,y) = (10,7) and r = 5.

Calculate k using the formula.

(x-h)^2 + (y-k)^2 = r^2

(x-5)^2 + (y-k)^2 = 5^2 add a h = 5 and r = 5 plug.

(10-5)^2 + (7-k)^2 = 25  Input x = 10 and y = 7

25 + (7-k)^2 = 25

(7-k)^2 = 25-25

(7-k)^2 = 0

7-k = sqrt (0)

7-k = 0

-k = 0-7

-k = -7

k = 7

(h,k) = is the center (5,7)

Updated to (x-5) + (y-7) = 25, we have (x-h) + (y-k) = r2.

Therefore The equation of the circle is   (x-5)^2 + (y-7)^2 is25

Answer:

11 minutes and 15 seconds (11.25 minutes/ 11 and 1/4)

Step-by-step explanation:

create the corresponding ratio by dividing 200 by 15, 200 calories per 15 minutes. Which equates to 40 calories every three minutes which means 40/3 or 13 1/3 calories every minute. You can verify this by multiplying 15 and 40/3 to get 200 again.

The last step is to divide the calories burned by the corresponding ratio (40/3)

150/(40/3) = 11.25

and .25 or 1/4 of 60 seconds(in a minute) is 15 since 60/4 = 15.

Answer:

See Below

Step-by-step explanation:

ABCD primes all correspond to x and y values on the graph.

A=

B=

C=

D=

1) y- intercept

2) time of max height

3) time when balloon hits ground

4) x-intercept

5) max height  

6) Initial height

So lets look at (0,A)

This would count as the y - intercept as well as the height they started throwing the balloons.

Soo....

A = y-intercept; Initial height

Now, (B,C)

This is the highest point on the graph, therefore it would be the max time and max height.

If we look at this as a person behind the line throwing the ballon, the y would be the height and the x would be the time

B = Time of max height

C=Max height

(D,0)

From the visual above, this point would be where the balloon hits the ground

From the visual in our head, x is time and y is height

Since d is the x, it is the time when the balloon hits the ground. And since

y =0, D is also the x intercept

D =  x intercept, Time when balloon hits ground

Therefore,

A = y-intercept; Initial height

B = Time of max height

C=Max height

D =  x intercept, Time when balloon hits ground

Hope this helps! =D

Answer:

Answer C

Step-by-step explanation:

This is because acute triangles have angles that are under 90 degrees and Option A would be true to what you are trying to make false and B & D are false because they have angles that go over 90 degrees.

The other statements that provide contradiction to the given expression are option (B) and (C).

An elementary polygon having three sides and three vertices is a triangle. There are three internal angles since it has three sides. An acute angle is one that ranges in measurement from 0° to 90°. A form of triangle called an acute triangle has acute angles at each of its three internal angles.

In the option (A),

the three angles could be 30°, 30°, and 30°.

These angles contradict the basic property of triangle.

Which is sum of all the triangles are 180°.

In the option (B),

the three angles could be 30°, 60°, and 90°.

The above angles hold the property of an acute triangle.

In the option (C),

The three angles could be 30°, 70°, and 80°.

The above angles also hold the property of an acute triangle.

In the option (D),

The three angles could be 30°, 30°, and 120°.

Angle 120° greater than 90°.

This statement contradicts the basic property of an acute triangle.

Therefore, the other statements that provide contradiction to the given expression are option (B) and (C).

Answer:

The total distance he drove is 350 miles, with an average speed of 46.67 miles/hour.

Step-by-step explanation:

Let [tex]t_1[/tex] and [tex]t_2[/tex] be the time of driving at a slower rate and at a faster rate respectively.

Given that the total distance = d

The speed for the first 150 miles = 60 miles/hour.

So, [tex]150=60\times t_1[/tex] [ as distance = speed x time]

[tex]\Rightarrow t_1=2.5[/tex] hours.

The remaining distance [tex]= d-150[/tex] miles.

Speed for the remaining distance = 60 miles/hour.

As the time he spent driving at the faster speed was twice the time he spent driving at the slower speed,

So, the time of driving at a faster rate, [tex]t_2 = 2t_1=2\times2.5=5[/tex] hours

So, [tex]d-150=60\times t_2[/tex] [ as distance = speed x time]

[tex]\Rightarrow d-150=20\times 5=100[/tex]

[tex]\Rightarrow d = 100+150=350[/tex] miles.

The average speed of the journey = (Total distance)/(Total time taken )

[tex]=d/(t_1+t_2)[/tex]

=350/(2.5+5)

=350/7.5

=46.67 miles/hour.

Hence, the total distance he drove is 350 miles, with an average speed of 46.67 miles/hour.
