The required shortest between the two houses is given as 10 miles. Option B is correct.

In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.

Here,
Matthew lives 6 miles east of the school drew lives 8 miles north of the school.

Let's assume, the position of Mathew and drew house create the right angle with the school,
hypotenuse distance between Mather and Drew's house be x,
Applying the Pythagoras theorem,

x = √[8² + 6²]
x = √[100]
x = 10 miles

Thus, the required shortest between the two houses is given as 10 miles. Option B is correct.

Step-by-step explanation:

As you can see sphere's diameter = to a cube's edge...so the diameter of the sphere is also 12 cm. So its radius is 6 cm.

v= 4/3*πr³

v=4/3*3.14*6³

v=904.32

The volume of the sphere is about 904 cubic centimeters.

ur question is incomplete. what is angle COD

Answer:

The first where z = -1.78 and p-value = 0.0375 would be the correct answer

Hope it helps

Using the z-distribution, it is found that the test statistic and the p-value of the test are given as follows:

z = –1.78, P-value = 0.0375.

At the null hypothesis, it is tested if the proportion is of 85%, that is:

[tex]H_0: p = 0.85[/tex]

At the alternative hypothesis, it is tested if it is less than that, hence:

[tex]H_1: p < 0.85[/tex].

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

In this problem, we have that the parameters are given as follows:

[tex]n = 50, \overline{p} = 0.76, p = 0.85[/tex]

Hence, the test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.76 - 0.85}{\sqrt{\frac{0.85(0.15)}{50}}}[/tex]

z = -1.78.

Using a z-distribution calculator, considering that we have a left-tailed test, as we are testing if the proportion is less than a value, the p-value is of 0.0375.

Janine has 48 hockey cards in one book and 105 hockey cards in another book. Therefore, the total hockey cards will be:

= 48 + 105

= 153 hockey cards

Since the hockey cards come in packages of 5 cards, the number of packages that she will buy will be:

= 153/5

= 30 3/5

= 31

Therefore, she'll buy 31 packages

Answer:

D) -9.7 and 9.7

E) 2.8 and -2.8

Answer:

Step-by-step explanation:

y = 6X

so this is a direct variation , b/c as X goes up, so does Y

The equation that models the data is y = 6x

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

To determine whether the data in the table represents a direct or inverse variation, we need to check whether the ratio of x to y is constant.

When we divide each y-value by its corresponding x-value, we get the ratios:

6/1 = 6

12/2 = 6

30/5 = 6

60/10 = 6

We see that the ratio of y to x is constant, which means that the data represents a direct variation.

To write an equation to model the data in the table, we can use the formula for direct variation, which is:

y = kx

where k is the constant of variation.

To find k, we can use any of the given data pairs.

For example, we can use the first pair (x = 1, y = 6):

6 = k(1)

Solving for k, we get:

k = 6/1 = 6

Thus,

The equation that models the data is y = 6x

Answer:

80 degrees

Step-by-step explanation:

one half of the circle makes a straight line and that will equal 180 degrees so 60+45=105

180-105=80

so the missing angle is x=80

Answer:

x = 75 degrees

Step-by-step explanation:

60 + 60 = 120

45 + 45 = 90

120 + 90 = 210

360 - 210 = 150

150 / 2 =75 degrees

Answer:

68°

Step-by-step explanation:

Equations:

To solve for y we have to use the sine rule which is defined as:

[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]

Side a is opposite from angle A, side b is opposite from side B, etc.

Solving for y:

Let's say angle A was the angle we are trying to find. Then we can re-write the sine rule as:

[tex]\frac{sin(y)}{250} =\frac{sin(48)}{200}[/tex]

Let's re-arrange this for the angle y:

[tex]sin(y)=250 * \frac{sin(48)}{200} \\y=sin^-1(250 * \frac{sin48}{200} )[/tex]

Typing this into a calculator gives the answer: [tex]y = 68.26...[/tex] which is 68 degrees rounded to the nearest whole degree.

In a 30-60-90 triangle, the side opposite the 30° is the other leg multiplied by 1/√3.

x= [tex]\frac{3}{\sqrt{3} } =\frac{3\sqrt{3} }{\sqrt{3}*\sqrt{3} } =\frac{3\sqrt{3} }{3} =\sqrt{3}[/tex]
