The total number of centimeters they both ran is 745000 centimeters. Option D is correct.

How do we determine the distance between two objects?

The distance between two objects can be determined by finding their difference.

From the given information:

Paula ran 3 1/4 kilometersOmar ran 4200 meters

The way to solve this is by converting all the distances to meters.

Paula = 3250 metersOmar = 4200 meters

Difference in their distance = (4200 - 3250) metersDifference in their distance = 950 meters.

The total number of centimeters they both ran is:

= (420000+325000) centimeters

= 745,000 centimeters

Therefore, we can conclude that Omar ran 950 meters farther than Paula. The total number of centimeters they both ran is 745000 centimeters.

There are no solutions to the system of inequalities shown belo
y<-2x+7
y > 3x + 1
A. True
B. False

Answers

Answer:

False

Step-by-step explanation:

Here's a simple little trick to tell wether a system of inequalities has any solutions or not, just by looking at it:

If the slopes are the same but the y-intercepts are different, the system has no solutions.

If the slopes are different, the system has only one solution.

If the slopes are the same and the y-intercepts are the same, then the system has infinitely many solutions.

By following this logic, since the system given has different slopes, it only has one solution. Therefore your answer is false.

Triangle ABC is an isosceles triangle. Angles B and C are base angles, with measurements of (11x −10)° and (7x + 10)°, respectively. What is m∠A?

Group of answer choices

90°

85°

35°

Answers

Answer:

m∠A = 90°

Step-by-step explanation:

In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!

m∠B = m∠C

11x - 10 = 7x + 10

4x - 10 = 10

4x = 20

x = 5

Now let's insert x back in the expressions for angles.

m∠B = (11x − 10)° = (11(5) − 10)° = 45°

m∠C = (7x + 10)° = (7(5) + 10)° = 45°

Sum of all angles in the triangle is 180°. Let's make an equation.

m∠A + m∠B + m∠C = 180°

m∠A + 45°+ 45° = 180°

m∠A  = 90°

If there are 300 houseflies in the study, how many of them will live longer than 21 days?

Answers

The 48 flies of them will live longer than 21 days if there are 300 houseflies in the study.

What is a normal distribution?

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have mean u = 18 days

SD = 3 days

X = 21 days

From the formula:

Z = (X - u)/SD

Z = (21 - 18)/3 = 1

P(x<21) = 0.84134

P(x>21) = 1 - P(x<21) = 0.15866

Number of flies = 300×0.15866 = 47.59 ≈ 48 flies

Thus, the 48 flies of them will live longer than 21 days if there are 300 houseflies in the study.

This season, the probability that the Yankees will win a game is 0.52 and the
probability that the Yankees will score 5 or more runs in a game is 0.53. The
probability that the Yankees lose and score fewer than 5 runs is 0.39. What is the
probability that the Yankees will lose when they score 5 or more runs?

Answers

Answer:

The probability of scoring fewer than 5 runs when they win is P = 0.19

How to find the probability?

We know that:

The probability of winning a game is p = 0.53

The probability of scoring 5 or more runs is q = 0.59

The probability of winning and scoring 5 or more runs is k = 0.43

Notice that the joint probability is different than the product of the individual probabilities, this means that the events are not independent.

So, we know that the probability of winning is 0.53

Now, given that they win, the probability of scoring 5 or more times will be q' such that:

0.53*q' = 0.43

q' = 0.811

This means that when they win, the probability of scoring more than 5 times is 0.81

Then the probability of scoring less than 5 times when they win is 1 minus the above probability:

P = 1 - 0.81 = 0.19

The probability of scoring fewer than 5 runs when they win is P = 0.19

The probability score in fewer than 5 runs. Is p=0.19

A. 60 cups
B. 45 cups
C. 30 cups
D. 18 cups

Answers

The closest to the maximum number of cups the punch bowl can hold is 30

How to determine the number of cups?

The given parameters are:

1 cup = 15 cubic inches

Diameter of bowl, d = 12 inches

The radius is the half of the diameter.

So, we have:

r = 6

The volume of the bowl is then calculated using:

[tex]V = \frac{2}{3}\pi r^3[/tex]

This gives

[tex]V = \frac{2}{3}\pi * 6^3[/tex]

Evaluate

V = 452.16

The maximum number of cups is then calculated using:

Cups = 452.16/15

Evaluate

Cups = 30.1444

Approximate

Cups = 30

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6.6^2 + x^2 = 6.8^2

43.56+x^2=46.24

Subtract 43.56 from each side

x^2 = 46.24-43.56

x^2 =2.68
