Answer:
6 3/8
Step-by-step explanation:
FIrst, reciprocal means that you have to change the order of the fraction.
8 1/2 = 17/2
1 1/3 = 4/3
17/2 by the reciprocal of 4/3 = 17/2 by (this word means to multiply) 3/4
17/2 * 3/4 = 51/8 = 6 3/8
ab" that goes through points (0,9)
Write an exponential function in the form y
and (5,2187)
9514 1404 393
Answer:
y = 9(3^x)
Step-by-step explanation:
We assume you want a function in the form ...
y = a(b^x)
that passes through points (0, 9) and (5, 2187).
Filling in the given point values, we have ...
9 = a(b^0) = a
2187 = a(b^5) = 9(b^5) . . . . using the above value of 'a'
Dividing the second equation by 9 and taking the 5th root, we find b.
(2187/9) = b^5
243^(1/5) = b = 3
The exponential function is ...
y = 9(3^x)

Assume we cut the last piece of the pie into two sections (1 and 2) along ray BD
such that m∠ABD = 2x+3, m∠CBD = 4x+7, and m∠ABC = 40°. Based on this information,
would you ask for section 1 or section 2 (you have to pick one) for dessert? Provide numerical
evidence to back up your choice. Explain your reasoning and your methods.
Answer:
Section 2
Step-by-step explanation:
I will pick the section with the largest angle.
Let's determine the size of the angle of each section.
Given:
m∠ABD = 2x+3,
m∠CBD = 4x+7,
m∠ABC = 40°
Thus:
m<ABD + m<CBD = m<ABC (angle addition postulate)
Substitute
2x + 3 + 4x + 7 = 40
Add like terms
6x + 10 = 40
6x + 10 - 10 = 40 - 10
6x = 30
6x/6 = 30/6
x = 5
✔️m∠ABD = 2x+3
Plug in the value of x
m<ABD = 2(5) + 3 = 13° (section 1)
✔️m∠CBD = 4x+7
m∠CBD = 4(5) + 7
m∠CBD = 27° (section 2)
✅I will pick section 2 because it is the section with the largest angle, which means it is the biggest.

Answer:
x=16°
Step-by-step explanation:
tanθ=opposite/adjacent
tan(<CAB)=BC/AB
<CAB=tan⁻¹(21/29)=35.9097308°
tanθ=opposite/adjacent
tan(<DAB)=BD/AB
<DAB=tan⁻¹((21/2)/29)=19.90374954°
<CAB=<DAB+x
x=<CAB-<DAB
=35.9097308-19.90374954
x=16.00598126°
Miss Lin bought 40 raisin, butter and curry buns for a class party. The ratio
of the number of raisin buns to the number of butter buns to the number of
curry buns was 7:5:8. Find the number of curry buns Miss Lin bought.
Answer:
Number of curry buns is 16.
Step-by-step explanation:
Total number of buns =40.
Ratio of number of raisin buns to the number of butter buns to the number of curry buns = 7:5:8
Let number of raisin buns = 7X.
Let number of butter buns =5X.
Let number of curry buns = 8X.
Therefore,
7X+5X+8X = 40
20X = 40
X= (40/20) = 2.
Therefore number of curry buns =8X = 8×2 =16.

A salesperson earns $300 per week, plus a 25% commission on each sale made. How much would the salesperson earn if he sold $650 worth of merchandise in one week?
Round to two decimal places
Answer:
$800 = $300 +.05(x), x being the amount that must be sold
Subtract 300 from both sides
$500= .05(x)
Divide by .05
x=$10000

Which combination of shapes can be used to create the 3-D figure?
a 3D figure with bases that are congruent regular polygons with 8 sides that are connected by congruent polygons which have a length greater than their width
Two regular octagons and eight congruent rectangles
Two regular pentagons and five congruent squares
Two regular octagons and eight congruent squares
Two regular pentagons and five congruent rectangles
A 3-D figure is a shape that its three surfaces can be observed at the same time. Therefore, required answer to the given question is: A. Two regular octagons and eight congruent rectangles.
When the length, width and height of a given shape can be observed at the same time, then its is said to be in a 3-D. However, polygons are shapes which has 3 or mores sides. Examples are: trigon, hexagon, octagon etc.
Thus, since the 3-D figure required in the question has two bases in the shape of regular octagon, which should have 8 sides connected by congruent polygons of length greater than their width.
This implies that the sides of the figure must be made up of eight congruent rectangles, because the 3-D figure has eight regular sides (which would be the width of the rectangles). Then, the height of the figure would be the length of the rectangles.
So, the correct option to the given question is A. Two regular octagons and eight congruent rectangles.
A sketch is attached to this answer for more clarifications.

An automobile manufacturer has developed a new compact automobile. A random sample of 64 of the new automobiles showed that the automobiles had a sample mean mileage of 28.75 miles per gallon and a sample standard deviation of 3.4 miles per gallon. a) Find the 95% confidence interval for the population mean mileage, and state your conclusion. b) Find the 98% confidence interval for the population mean mileage, and state your conclusion.
Answer:
The 95% confidence interval for the population mean mileage is
(27.917, 29.593)
The 98% confidence interval for the population mean mileage
(27.737, 29.762)
Step-by-step explanation:
Step(i):-
Given that the random sample size 'n' = 64
Given that the mean of sample x⁻ = 28.75miles
Given that the standard deviation of the sample (S) = 3.4 miles
Degrees of freedom = n-1 = 64-1 =63
t₀.₀₅ = 1.9983
Step(ii):-
95% confidence interval for the population mean mileage is determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} })[/tex]
[tex](28.75-1.99\frac{3.4}{\sqrt{64} },28.75 + 1.99 \frac{3.4}{\sqrt{64} } )[/tex]
(28.75 - 0.845 , 28.75 + 0.845)
(27.917 , 29.593)
Step(iii):-
98% confidence interval for the population mean mileage is determined by
[tex](x^{-} - t_{0.02} \frac{S}{\sqrt{n} } , x^{-} + t_{0.02} \frac{S}{\sqrt{n} })[/tex]
[tex](28.75-2.3824\frac{3.4}{\sqrt{64} },28.75 + 2.3824 \frac{3.4}{\sqrt{64} } )[/tex]
(28.75 - 1.01252 , 28.75 + 1.01252)
(27.737 , 29.762)
Final answer:-
98% confidence interval for the population mean mileage is

Solve the system.
9x2 + 4(y - 2)2 = 36
x² = 2y
Answer:
[tex]x =2[/tex]
[tex]y =2[/tex]
Step-by-step explanation:
Given
[tex]9x^2 + 4(y - 2)^2 = 36[/tex]
[tex]x^2 = 2y[/tex]
Required
Solve
Substitute: [tex]x^2 = 2y[/tex] in [tex]9x^2 + 4(y - 2)^2 = 36[/tex]
[tex]9*2y + 4(y-2)^2 = 36[/tex]
[tex]18y + 4(y-2)^2 = 36[/tex]
Open bracket
[tex]18y + 4[y^2-2y - 2y + 4] = 36[/tex]
[tex]18y + 4[y^2-4y + 4] = 36[/tex]
Open bracket
[tex]18y + 4y^2-16y + 16 = 36[/tex]
Collect like terms
[tex]4y^2+18y-16y + 16 - 36 = 0[/tex]
[tex]4y^2+2y-20= 0[/tex]
Divide through by 2
[tex]2y^2+y-10= 0[/tex]
Expand
[tex]2y^2+5y - 4y-10= 0[/tex]
Factorize
[tex]y(2y + 5) - 2(2y + 5) = 0[/tex]
Factor out 2y + 5
[tex](y -2)(2y + 5) = 0[/tex]
Split
[tex]y - 2 =0\ or\ 2y + 5 = 0[/tex]
Solve for y
[tex]y =2 \ or\y = -\frac{5}{2}[/tex]
We have:
[tex]x^2 = 2y[/tex]
Make x the subject
[tex]x = \sqrt{2y[/tex]
The above is true for positive y values.
So: [tex]y =2[/tex]
This gives
[tex]x = \sqrt{2*2[/tex]
[tex]x = \sqrt{4[/tex]
[tex]x =2[/tex]
What is the area of a triangle with vertices (1,0) (5,0) (3,4)
Answer:
The area of the triangle is of 8 units of area.
Step-by-step explanation:
Answer:
The area of the triangle is of 21 units of area.
Step-by-step explanation:
The area of a triangle with three vertices [tex](x_1,y_1),(x_2,y_2),(x_3,y_3)[/tex] is given by the determinant of the following matrix:
[tex]A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|[/tex]
In this question:
Vertices (1,0) (5,0) (3,4). So
[tex]A = \pm 0.5 \left|\begin{array}{ccc}1&0&1\\5&0&1\\3&4&1\end{array}\right|[/tex]
[tex]A = \pm 0.5(1*0*1+0*1*3+1*5*4-1*0*3-0*5*1-1*1*4)[/tex]
[tex]A = \pm 0.5*(20-4)[/tex]
[tex]A = \pm 0.5*16 = 8[/tex]
The area of the triangle is of 8 units of area.

Answer:
9. [tex] \frac{1}{10,000} = 0.0001 [/tex]
10. [tex] \frac{1}{81} [/tex]
Step-by-step explanation:
9. [tex] x^{-4} [/tex]
Evaluate when x = 10.
Substitute x = 10 into the expression
[tex] 10^{-4} [/tex]
Apply the negative exponent rule ([tex] a^{-n} = \frac{1}{a^n} [/tex])
Thus:
[tex] = \frac{1}{10^4} [/tex]
[tex] = \frac{1}{10^4} = \frac{1}{10,000} = 0.0001 [/tex]
10. [tex] 2a^{-1}b^{-3} [/tex]
Evaluate when a = 6 and b = 3
Substitute
[tex] (2*6^{-1})(3^{-3}) [/tex]
Apply the negative exponent rule
[tex] (2*\frac{1}{6})(\frac{1}{3^3}) [/tex]
[tex] (\frac{2}{6})(\frac{1}{27}) [/tex]
[tex] \frac{2*1}{6*27} [/tex]

Mandy and Randy are each playing with a beach ball. Mandy's ball has a diameter of 12 inches. Randy's ball has a diameter that is twice as large as Mandy's ball. How much larger is the volume of Randy's ball? Show and explain your reasoning.
Answer:
Randy's ball is 904.78 larger than Mandy's.
Step-by-step explanation:
Using math, we find that Mandy's ball is 904.78 inches in volume and if Randy's is twice the size that's, 904.78 x 2 = 1809.56. so Randy's ball is 904.78 larger than Mandy's
find the value for x y and z
Answer:
All triangles add up to 180 degrees so...
180 - 43 - 59 = 78 degrees.
So x - 78 degrees.
x and y are supplementary angles so...
180 - 78 = 102.
So y = 102.
180 - 102 - 49 = 29 degrees
So z = 29 degrees
