What is the area of a circular region with a 20-ft
diameter?
A)22571 in 2
B)1007 ft2
C) 4007 ft2
D) 2251 ft2
Please help and how would I draw it ?
Answer:
B) 100[tex]\pi[/tex] ft²
Step-by-step explanation:
The area of a circle is pi r-squared. The radius is half the diameter, so it would be:
[tex]\pi[/tex](10)² = 100[tex]\pi[/tex]
A horseback rider travels 2 miles in 12 minutes. At this speed, how long does it take to travel 5 miles? Use the equation d=rt, where d is distance, r is rate, and t is time.
Answer:
30 minutes
Step-by-step explanation:
rate = 2/12 = 1 mile/6minutes
d = rt
5 = 1/6t
t= 5/(1/6)
t = 30 minutes

How many bags of topsoil does Betsy need to cover her flower bed?
Answer:
3 bags of topsoil is needed
Step-by-step explanation:
base = 20m
height = 6 m
Area of flower bed = [tex]\frac{1}{2}*base*height\\[/tex]
[tex]= \frac{1}{2}*20*6\\\\= 10*6\\= 60 square feet[/tex]
Number of bags= Total area of flower bed ÷ 20

I have attached an image showing the triangle with angle and distance depicted in the question.
Answer:
151 miles
Step-by-step explanation:
We have to first find the unknown angle in the triangle.
Sum of angles in a triangle is 180°.
Thus, if we call angle at Norfolk A, we have;
A = 180 - (83 + 31)
A = 66°
Using sine rule, we can find the distance which we will term as a.
Thus;
a/sin 83 = 139/sin 66
a = (139 × sin 83)/sin 66
a = 137.963915/0.913545
a ≈ 151 miles
PLEASE HELP ME! 5TH GRADEThe solid figure is separated along the dotted line into two rectangular prisms. What are the volumes of the two rectangular prisms? What is the volume of the solid figure? Use the drop-down menus to show your answer. A solid is made up of 2 rectangular prisms. The total length of the solid is 20 inches. First rectangular prisms has a height of 5 inches, and width of 4 inches. Second rectangular prisms have 4 inches, a height of 8 inches, and a width of 4 inches. The volume of two rectangular prisms are Choose... cubic inches and 128 cubic inches. The volume of the solid figure is Choose... cubic inches.
The volume of the solid figure is the amount of space in it
The volume of the solid figure is 448 cubic inches
How to determine the volume of the figures?For the first rectangular solid, we have:
Height = 5 inchesWidth = 4 inchesLength = 16 inchesSo, the volume is:
Volume = 5 * 4 * 16 cubic inches
Volume = 320 cubic inches
For the second rectangular solid, we have:
Height = 8 inchesWidth = 4 inchesLength = 4 inchesSo, the volume is:
Volume = 8 * 4 * 4 cubic inches
Volume = 128 cubic inches
The volume of the solid figure is then calculated as:
Volume = 320 cubic inches + 128 cubic inches
Volume = 448 cubic inches
Hence, the volume of the solid figure is 448 cubic inches

What is a linear equation?A linear equation is defined as a equation that has either one or two variables without exponents. A linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
For the given situation,
The equation is y = 0.21x.
The time taken by the cell phone battery to charge to 100%,
⇒ [tex]100\% = 0.21x[/tex]
⇒ [tex]100\%=1[/tex]
Thus, [tex]1=0.21x[/tex]
⇒ [tex]x=\frac{1}{0.21}[/tex]
⇒ [tex]x=4.76[/tex] ≈ [tex]5[/tex]
Hence we can conclude that the time taken by the cell phone battery to charge 100% is 5 hours.

Please assist with the problem:
3 ^ -(sqrt 3)
Answer:
Step-by-step explanation:
y = 3 ^ - sqrt(3)
y = -sqrt(3) * log(3)
Log (3)= 0.47712
- sqrt(3) = - 1.732
y = 0.47712 * -1.732
y = - 0.82637
The y really has no meaning. I just used it so I could get from 1 line to the next.
Look carefully at how that - sqrt(3) was handled. You are not taking the square root of -3.

Find the area of the square in inches2 and enter your answer below. Do not include units in your answer.
Answer:
11.56
Step-by-step explanation:
The area formula is just Length * Height. Since this shape is a square, both the length and height are equivalent to the same thing, 3.4. So, all we have to do is multiply 3.4 * 3.4, or we can do 3.4^2.
The nutrition label for Oriental Spice Sauce states that one package of sauce has 1110 milligrams of sodium. To determine if the label is accurate, the FDA randomly selects 170 packages of Oriental Spice Sauce and determines the sodium content. The sample has an average of 1172.61 milligrams of sodium per package with a sample standard deviation of 241.88 milligrams. Step 2 of 2 : Using the confidence interval approach, is there evidence that the sodium content is different from what the nutrition label states
Answer:
[tex]1124.28 \text { to } 1220.94[/tex]
Step-by-step explanation:
A 99% confidence interval for the mean sodium content in Oriental Spice Sauce is,
First, compute t -critical value then find confidence interval.
The t critical value is,
The sample size is small and two-tailed test. Look in the column headed [tex]\alpha=0.01[/tex] and the row headed in the t distribution table by using degree of freedom is,
d . f . =n-1
=170-1
=169
The t critical value is 2.605 .
[tex]99 \% \text { C.I. } &=\bar{x} \pm t_{c} \times s / \sqrt{n}[/tex]
[tex]=1172.61 \pm 2.605 \times 241.88 / \sqrt{170}[/tex]
[tex]=1172.61 \pm 48.33[/tex]
[tex]=1124.28 \text { to } 1220.94[/tex]
