there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?

Answers

Answer 1

Answer:6 students remaining

Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.

Answer 2
Total no of students: 45

Students who gave speech yesterday:
2/3 of 45
= 30

Students left= 45-30 = 15
Students who gave speech today:
3/5 of 15
= 9

No. of who still haven’t give speech
= 15-9
= 6 students

Answers

Answer:

a. circumference

b. area

c. area

d. circumference

Step-by-step explanation:

a. You are using the circumference formula to find the distance around a CIRCULAR track, if you used area, that would include the space in between the track as well. You are only trying to find the track line. ( you can draw a picture of a track and show what you are finding. )

b. You are trying to find the amount of area that the tiles make up in the circular floor, how much of the floor the tiles take up.

c. You are trying to find how much of the oil takes up of the WHOLE bottom of the frying pan.

d. Finding the circumference of your wheel can help determine the distance the car traveled. If you used area, it would not be useful.

Calculate the straight line distance between the points (-10, -7) and (-8,1).
G.2(B)

Answers

Answer:

2√(17) or about 8.2462 units.

Step-by-step explanation:

We want to determine the distance between the two points (-10, -7) and (-8, 1).

We can use the distance formula. Recall that:

[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Substitute and evaluate:

[tex]\displaystyle \begin{aligned} d &= \sqrt{((-10)-(-8))^2 + ((-7) - (1))^2} \\ \\ &=\sqrt{(-2)^2+(-8)^2} \\ \\ &= \sqrt{(4) + (64)} \\ \\ &= \sqrt{68}\\ \\ &= 2\sqrt{17}\end{aligned}[/tex]

Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.

[tex] \qquad \qquad\large\rm{Together \: We \: Go \: Far!} \\ \qquad \qquad \sf \small{\red{♡}\:Swifties\:\red{♡}}[/tex]

Question :-

Calculate the straight line distance between the points (-10, -7) and (-8, 1).

Answer :-

The straght line distance between the two points is 8.2462 units.

[tex] \rule{200pt}{3pt}[/tex]

Solution :-

As per the provided information in the given question, we have been given that:

[tex](x_1, y_1) = (-10, -7)[/tex][tex](x_2, y_2) = (-8, 1)[/tex]

To calculate the distance between the two points, we will apply the formula below:

[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \: \: }}[/tex]

Substitute the given values into the above formula and solve for d:

[tex]\sf:\implies{ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}}[/tex]

[tex]\sf:\implies{d = \sqrt{[-8 - (-10)]^2 + [1 - (-7)]^2}}[/tex]

[tex]\sf:\implies{d = \sqrt{(2)^2 + (8)^2}}[/tex]

[tex]\sf:\implies{d = \sqrt{4 + 64}}[/tex]

[tex]\sf:\implies\bold{d = \sqrt{68} \approx 8.2462 \: units}[/tex]

Therefore :-

The straght line distance between the two points is 8.2462 units.

[13, ∞)
[14, ∞)

[16, ∞)

Answers

Answer:

Its C

Step-by-step explanation:

Just finished the homework and got it right

Using exponential functions, it is found that the correct option is given by:  [15, ∞)

-------------------------

The exponential function given in this exercise is:

[tex]M(t) = 25000(\frac{4}{5})^t[/tex]

-------------------------

The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:

[tex]M(t) < 1000[/tex]

Thus, we have to solve the exponential inequality.

[tex]M(t) < 1000[/tex]

[tex]25000(\frac{4}{5})^t < 1000[/tex]

[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]

[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]

[tex]-0.0969t < -1.39794[/tex]

[tex]0.0969t > 1.39794[/tex]

[tex]t > \frac{1.39794}{0.0969}[/tex]

Given are the slopes of several lines. Indicate whether each line is horizontal, vertical, rises from left to right, or falls from left to right.

Answers

Answer:

Rises from left to rightVertical LineHorizontal LineFalls from left to right

Step-by-step explanation:

Keep in mind we read graphs from left to right just like how we read and write.

A positive slope will be increase from left to right. A negative slope with decrease left to right. A vertical line will have a undefined slope.A horizontal line will have a slope of 0.

We can use those tips to solve the problem.

Option A:

4/5 is a positive slope so it will rise from left to right.

Option B:

No slope automatically means "undefined" so that falls in the definition of a vertical line.

Option C:

A slope of 0 is defined as a horizontal line.

Option D:

-4/5 is a negative slope so it will fall from left to right.

Best of Luck!
