Answers

Answer 1

Rate is given by:
rate=(distance )/(time)
Martin's rate will be:
(3 1/3)/(1/6)
=(10/3)/(1/6)
=20 meters per hour

Alexia's rate is:
(17 1/2)/(5/6)
=(35/2)/(5/6)
=21 meters per hour

find the total surface area of the pyramid

Answers

To find the surface area of a pyramid, we need to find the area of all the faces and add them up.

4 * 6 = 24
24 / 2 = 12

There are four sides (not including the base) in this pyramid, so we should multiply this by 4.

12 * 4 = 48

Now, we find the area of the base.

6 * 6 = 36

We add up all of the numbers:

48 + 36 = 84

84 in^2 is the answer.

The supplement of an angle has a measure that is 20 degrees more than twice the measure of an angle , x degrees. Which equation can be used to find the value of x?

A) 2x + 20 = 90
B) 2x + 20 = 180
C)(2x + 20) + x = 90
D)(2x + 20) + x = 180

Please Help Me

Answers

Selection D is appropriate.

_____
I would write it differently.
.. 180 -x = "supplement of an angle"
.. 2x +20 = "20 more than twice the measure"
These are said to be equal, so I would write it as
.. 180 -x = 2x +20
Of course, adding x to both sides of this equation makes it
.. (2x +20) +x = 180 . . . . . . matches selection D

Step-by-step explanation:

n cold climate areas, trucks are used to disperse salt on the roads in order to de-ice the roads, making them safe for travel. In some cases, cone- shaped sheds store the salt during the off-season, or until the roads need to be de-iced. This large salt storage shed sits 12 feet above the ground and holds approximately 51.4 cubic feet of salt. To the nearest hundredth of a foot, what is the radius of the large storage shed? Use 3.14 for . In your final answer, include all of your calculations.

Answers

To find the radius of the circular storage shed, you will use the formula for finding the volume of a cone (V=1/3 x pi x r^2 x h, where r is the radius and h is the height.

You will substitute in the information you know and then solve for the radius(r).

Please see the attached picture for the steps necessary to get an approximate radius of 2.02 ft as the radius.

The radius of the large storage shed is approximately 2.023 feet to the nearest hundredth of a foot.

To find the radius of the large storage shed, we need to use the formula for the volume of a cone, which is given by: [tex]\[ V = \frac{1}{3} \pi r^2 h \][/tex]

where V is the volume, r is the radius of the base, h is the height and [tex]$ \pi $[/tex]is approximately 3.14. We are given that the volume V is 51.4 cubic feet and the height h is 12 feet. We need to solve for r.

First, let's rearrange the formula to solve for r: [tex]\[ r^2 = \frac{3V}{\pi h} \][/tex]

Now, plug in the given values:

[tex]\[ r^2 = \frac{3 \times 51.4}{3.14 \times 12} \][/tex]

[tex]\[ r^2 = \frac{154.2}{37.68} \][/tex]

[tex]\[ r^2 \approx 4.093 \][/tex]

Now, take the square root of both sides to find r:

[tex]\[ r \approx 2.023 \][/tex]

So, the radius of the large storage shed is approximately 2.023 feet to the nearest hundredth of a foot.

Nolan used the following procedure to find an estimate for the square root of 18.
Step 1: Since 4^2=16 and 5^2= 25 and 16 < 18 < 25, the square root of 18 is between 4 and 5.
4.1^2=16.81
4.2^2=17.64
4.3^2=18.49
4.4^2=19.36
Step 3: Since 18.49 rounds to 18, 4.3 is the best approximation for the square root of 18.
In which step, if any, did Nolan make an error?
A) In step 1, the square root of 18.
is between 4 and 5 because the square root of 18 equals about 20 and 4 times 5= 20.
B) In step 2, he made a calculation error when squaring.
C) In step 3, he should have determined which square is closest to 18.
D) Nolan did not make an error.

Answers

Nolan correctly identified the square numbers before and after 18.

The square roots of them are 4 and 5.

Clearly, square root of 18 should lie between 4 and 5 only.

He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.

Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.

You don't need to understand the construction or why it works. You only need to accept the fact that it does. You can figure out the answers to this question by looking at the picture.

RT is tangent to circle Q -- TRUE. That is the point of the construction.

QT is a radius of circle Q -- TRUE. Q is the center and T is on the circle. A line segment from the center to a point on the circle is a radius.

m∠QSR = 90° -- FALSE. Those points lie on the same line. The measure of the angle is 180°.

QS = QT -- FALSE. S lies inside circle Q, so is closer to the center than T, which lies on the circle. (For some choice of point R, S might lie on the circle, but because this statement is not always true, it must be considered false.)

ΔRTQ is a right triangle -- TRUE. A tangent line is always perpendicular to the radius to the point of tangency. The construction succeeds because RTQ is inscribed in semicircle RTQ (centered at S). Such a triangle is always a right triangle.

A restaurant used 3 pounds of potatoes during a lunch rush. If they used 3/8 as much beef, how many pounds of beef did they use?

Answers

The restaurant used 3 pounds of potatoes, 3/8 of that would be 1.125. Thus, the restaurant used 1.125 pounds of beef during the lunch rush.

Final answer:

To find the amount of beef used when the restaurant used 3 pounds of potatoes during a lunch rush and used 3/8 as much beef, simply calculate 3 pounds * 3/8 to determine the amount of beef used, which is 1.125 pounds.

Explanation:

The restaurant used 3 pounds of potatoes during a lunch rush. If they used 3/8 as much beef, we can find the amount of beef used:

Calculate how much beef is equivalent to 3 pounds of potatoes: 3 pounds * 3/8 = 9/8 = 1.125 pounds of beef.

Therefore, the restaurant used 1.125 pounds of beef during the lunch rush.

Find the cardinal number for the following sets.

B = {102, 104, 106, ..., 252}

Answers

Cardinal number, more commonly called cardinality, is the number of members of a given set.

For example, if P={1,4,6}, cardinality is 3 because there are three member in the set.

For A, the numbers run consecutively from 102 to 155, so there are (155-102)+1=54 members. The cardinality is therefore 54
Similarly, for B={102,...252}, there are (252-102)+1=151 members. So the cardinality is 151.

The length of the shipping box =[tex]3\frac{3}{4} =\frac{15}{4} ft.[/tex]

Width = 3 ft.

Height =[tex]3\frac{1}{4} =\frac{13}{4} ft.[/tex]

Volume of shipping box can also be calculated by multiplying base area with the height of box.

Volume of box = base area x height =[tex]\frac{45}{4} .\frac{13}{4} = 36.6 cubic ft.[/tex]

Volume of packing cubes =[tex]\frac{1}{4} .\frac{1}{4} .\frac{1}{4} =\frac{1}{64}[/tex] cubic ft.

A conical hat has a radius of 7 inches and a height of 14. What’s the slant height

Answers

The slant height of a conical hat with a radius of 7 inches and a height of 14 inches is found by using the Pythagorean theorem, leading to a slant height of approximately 15.65 inches.

To find the slant height of a conical hat with a radius of 7 inches and a height of 14 inches, we use the Pythagorean theorem for the right triangle formed by the radius, height, and slant height of the cone. The slant height is the hypotenuse of this right triangle, while the radius and the height are the two legs.

The formula for the Pythagorean theorem is:

a^2 + b^2 = c^2

Where:

a is the radius of the cone (7 inches),

b is the height of the cone (14 inches), and

c is the slant height of the cone (what we are trying to find).

Substituting the values into the formula, we get:

7^2 + 14^2 = c^2

49 + 196 = c^2

245 = c^2

To find c, we take the square root of both sides:

c = √245

The slant height (c) is then calculated to be:

c ≈ 15.65 inches
