Answer:
103.18units³
Step-by-step explanation:
Area of the sector DEF = theta/360 * πr²
r is the radius
theta is the angle subtended at the centre
theta =70 degrees
radius DE = 13units
Substitute
Area of the sector = 70/360 * 3.14(13)²
Area of the sector = 7/36 * 530.66
Area of the sector = 3,714.62/36
Area of the sector = 103.18units³ (to the nearest hundredth)
Answer: 103.24

Casey recently purchased a sedan and a pickup truck at about the same time for a new business. The value of the sedan S, in dollars, as a function of the number of years t after the purchase can be represented by the equation S(t)=24,400(0.82)t. The equation P(t)=35,900(0.71)t2 represents the value of the pickup truck P, in dollars, t years after the purchase. Analyze the functions S(t) and P(t) to interpret the parameters of each function, including the coefficient and the base. Then use the interpretations to make a comparison on how the value of the sedan and the value of the pickup truck change over time.

Step-by-step explanation:
Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.

A furniture store bought a couch for $425 and marked the price up by 70%. Angela bought the couch with a 6% tax. How much did Angela payoff the couch?
Answer:
454.68
Step-by-step explanation: so this is how u do it......
Step 1) you need to turn the pursent into this kind of number ( 70% = 0.07)
Step 2)your need to subtract from the couch price (425$ - 0.07= 424.93)
Step 3) 424.93 is the sale price so 0.07 times 424.93 = ( 29.7451)
Step 4) 29.7451 is our tax price so ( tax + sale price ) 29.7451 + 424.93 = 454.6751
Step 5) round to the nerest cent = 454.68

Step-by-step explanation:
The drama club is ordering t-shirts for its members. A local t-shirt company charges $83.95 to set up the design plus $7.45 for each shirt. The drama club has budgeted $300 to spend on t-shirts.
Write an equation that you could solve to find the maximum number of shirts the drama club can order. Be sure to define your variable.
Answer:
The max # of shirts they can order is 29
Step-by-step explanation:
300 = 83.95 + 7.45x
216.05 = 7.45x
x = 29
Answer:
Step-by-step explanation:
83.95+7.45= 91.4
so they have
300
- 91.4
--------
208.6
so after they still have money left
Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance
Answer:
9.5
Step-by-step explanation:
Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance.
Step 1
We find the Mean of the numbers
Mean = Sum of terms/ Number of terms
Mean = 9+12+9+14+6/5
= 50/5
= 10
Step 2
We find the sample variance
Formula =
(x - Mean)²/n - 1
n = 5
= (9 - 10)²+(12 -10)²+(9- 10)²+(14-10)²+(6-10)²/5 - 1
= 1+ 4+ 1+ 16+16/5 - 1
= 38/5 - 1
= 38/4
= 9.5
Therefore, Sample variance = 9.5

What is the measure of angle A?
Answer:
∠ A = 35°
Step-by-step explanation:
The measure of the tangent- tangent angle A is half the difference of the intercepted arcs.
minor arc = 145°
major arc = 360° - 145° = 215°
Then
∠ A = [tex]\frac{1}{2}[/tex] ( 215 - 145) = [tex]\frac{1}{2}[/tex] × 70° = 35°

what's the surface area ratio & the volume ratio??
please help me ASAP!!
Answer:
Step-by-step explanation:
Volumes of two spheres A and B = 648 cm³ and 1029 cm³
Things to remember:
1). Scale factor of two objects = [tex]\frac{r_1}{r_2}[/tex] [[tex]r_1[/tex] and [tex]r_2[/tex] are the radii of two circles]
2). Area scale factor = [tex]\frac{(r_1)^2}{(r_2)^2}[/tex]
3). Volume scale factor = [tex]\frac{(r_1)^3}{(r_2)^3}[/tex]
Volume scale factor Or Volume ratio = [tex]\frac{V_A}{V_B}[/tex]
[tex]\frac{(r_1)^3}{(r_2)^3}= \frac{648}{1029}[/tex]
[tex]\frac{r_1}{r_2}=\sqrt[3]{\frac{648}{1029} }[/tex]
[tex]\frac{r_1}{r_2}=\frac{6(\sqrt[3]{3})}{7(\sqrt[3]{3})}[/tex]
[tex]\frac{r_1}{r_2}=\frac{6}{7}[/tex]
Therefore, scale factor = [tex]\frac{r_1}{r_2}=\frac{6}{7}[/tex]
≈ 6 : 7
Area scale factor Or area ratio = [tex](\frac{r_1}{r_2})^2=(\frac{6}{7})^2[/tex]
= [tex]\frac{36}{49}[/tex]
≈ 36 : 49
Volume scale factor or Volume ratio = [tex]\frac{648}{1029}[/tex]
= [tex]\frac{216}{343}[/tex]
≈ 216 : 343

Juicy's business Sweet Sauce is profiting at a rate 20,000 dollars per month. The starting balance in Sweet Sauce's account for 2020 was $50,000. How much money will be in Sweet Sauce's account after July 31st? Write an equation for this problem and answer the question. How much money will be in the account after 2 years?
Answer:
-The equation for this problem is:
y=50,000+20,000x
-The money in Sweet Sauce's account after July 31st is $190,000
-The money in the account after 2 years is $530,000.
Step-by-step explanation:
With the information provided, you can say that the money in the account would be equal to adding up the starting balance plus the profit per month for the number of months that have passed, which is:
y=50,000+20,000x, where:
y is the money in the account
x is the number of months that have passed
Now, to find the amount of money in the account after July 31st, you have to consider that this is the 7th month and you have to replace x with 7:
y=50,000+(20,000*7)
y=50,000+140,000
y=190,000
Also, to find the amount the amount of money in the account after 2 years, you have to consider that 2 years is equal to 24 months:
y=50,000+(20,000*24)
y=50,000+480,000
y=530,000

Answer:
Volume of the larger one = 476.5625
Step-by-step explanation:
Remark
This is a terrific little problem. Thanks for posting. I hope the answer is still useful to you. If the cylinders are similar it means that r and h are multiplied by a constant when moving from the smaller cylinder to the larger one. Everything else, believe it or not, remains the same.
Equations
Surface area of the smaller cylinder = 2pi*r^2 + 2pi*r*h
Surface area of the larger cylinder = 2*pi*(kr)^2 + 2pi*(kr)*(kh)
Surface area of the larger cylinder = k^2 (2*pi*r^2 + 2pi* r*h)
Solution
Surface area of the larger cylinder = k^2 (2pi*r^2 + 2pi*r*h)
============================= ==================
Surface area of the smaller cylinder (2pi*r^2 + 2pi*r*h)
surface area of the larger cylinder = k^2
surface are of the smaller cylinder = 1
200 / 128 = k^2 / 1 Divide the top and bottom of the left by 8
25 / 16 = k^2 Take the square roots of both sides
sqrt(25/16) = sqrt(k^2)
5/4 = k
Now work on the volume.
The volume of the larger cylinder = pi (kr)^2 (kh) = k^3 * pi * r^2 h
The volume of the smaller cylinder = pi * r^2 h
The volume of the larger cylinder to the smaller one = k^3 = 1.953125
x / 244 = 1.953125 Multiply both sides by 244
x = 1.953125 * 244
x = 476.5625

Steve uses 14 blue beads and 6 green beads to make a bracelet.
Which ratio compares the number of blue beads to the total number of beads in one bracelet?
Answer:
blue:total
14:20
Answer:
14:20
Step-by-step explanation:
because 14 + 6= 20 so blue beads are 14 and the other is alltogether 20 so it is 14:20 or 14 to 20
