Alicia sews costumesfor a school play.She takes an average of 86 minutes to sew each costume.How long would she take to sew 16 of these costumes

Answer:

The first one is D and the second one is B

Step-by-step explanation:

The first is D because the volume of a cylinder is v = π (pi) times the radius squared times the height of the cylinder.

so (π)(16^2)(7) =5629.73 ft^3

Then 1 ft^3 is = 7.5 gallons of water, so you multiple 5629.73 by 7.5 and round. Which gets you 42223

Answer:

x = 9

Step-by-step explanation:

The line splits the sides of the triangle in proportion (the ratios of the pieces is the same for both sides).

Setup:

[tex]\frac{8}{3x+1}=\frac{2}{x-2}[/tex]

"Cross multiply."

[tex]2(3x+1)=8(x-2)\\6x+2=8x-16\\18=2x\\9=x[/tex]

Answer:

5ft

Step-by-step explanation:

r = √v/πh

plug in known values

r= √628/ (3.14) 8

simplify

r= √628/ 25.12

r= √25

r = 5ft

Answer:

Add 8 to both sides of the equation.

−6x²−2−3x+8=0 Add −2and 8.

−6x²−3x+6=0

Factor −3 out of −6x²−3x+6.

−3(2x²+x−2)=0

Divide each term by −3 and simplify.

2x²+x−2=0

Use the quadratic formula to find the solutions.

(−b±√b2−4(ac))/2a

Substitute the values a=2 , b=1, and c=−2 into the quadratic formula and solve for x .

(−1±√12−4⋅(2⋅−2))/(2⋅2) Simplify.

x=−1±√174

The final answer is the combination of both solutions.

x=(−1−√17)/4, (−1+√17/)4

The result can be shown in multiple forms.

Exact Form:

x=(−1−√17)/4, (−1+√17)/4

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 325 grams and a standard deviation of 10 grams.

This means that [tex]\mu = 325, \sigma = 10[/tex]

a. Highest 10 percent

This is X when Z has a pvalue of 1 - 0.1 = 0.9, so X when Z = 1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = 10*1.28[/tex]

[tex]X = 337.8[/tex]

So 337.8 grams.

b. Middle 50 percent

Between the 50 - (50/2) = 25th percentile and the 50 + (50/2) = 75th percentile.

25th percentile:

X when Z has a pvalue of 0.25, so X when Z = -0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.675 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = -0.675*10[/tex]

[tex]X = 318.25[/tex]

75th percentile:

X when Z has a pvalue of 0.75, so X when Z = 0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = 0.675*10[/tex]

[tex]X = 331.75[/tex]

Between 318.25 grams and 331.75 grams.

c. Highest 80 percent

Above the 100 - 80 = 20th percentile, which is X when Z has a pvalue of 0.2. So X when Z = -0.841.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.841 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = -0.841*10[/tex]

[tex]X = 316.59[/tex]

Above 316.59 grams.

d. Lowest 10 percent

Below the 10th percentile, which is X when Z has a pvalue of 0.1, so X when Z = -1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.28 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = -1.28*10[/tex]

[tex]X = 312.2[/tex]

Below 312.2 grams

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

Center: (−2, −5); radius= 1

This means that [tex]x_0 = -2, y_0 = -5, r = 1[/tex]. So

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - (-2))^2 + (y - (-5))^2 = 1^2[/tex]

[tex](x + 2)^2 + (y + 5)^2 = 1[/tex]

This is the equation of the circle.

Answer: 10 laps

Step-by-step explanation: 60(minutes) divided by 6(minutes of orginal lap)

Answer:

Step-by-step explanation:

So we'll take the ratio of  3:8  to mean  3 to 8   ,  which is 11 total parts.

since we know that part, and we can see that the x coordinate goes from -15 to 7, which is a total  of 22  and that y goes from 18 to 7, which is a total of 11 then we know that  we can just break up each into their 3:8 ratios

3:8=11 for the y component

6:16=22 for the x component

so subtract 3 from the B point for the y or add 3 to the A point , either works here,   Let's go from B so y = 10 (7+3)  and x = 1  (7-6)

So a point at (1,10) will be on the line and at a ratio of 3:8  :)

Step-by-step explanation:

In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...

  (x, y) = (r·cos(θ), r·sin(θ))

From the various trig definitions and identities, we also know that ...

  cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y

For the given (x, y) = (-4, -5), the cotangent is ...

Answer:

8. 8/9 is not the multiplicative inverse of –1⅛

9. 0.3 is the multiplicative inverse of 3⅓

Step-by-step explanation:

To answer the above questions, we must understand the meaning of multiplicative inverse. This is illustrated below:

Let y be the number.

The multiplicative inverse of y denoted by y¯¹ (or 1/y) when multiplied with y will give an identity of 1 i.e

y × y¯¹ = 1

Or

y × 1/y = 1

Now, let us answer the questions given above by calculating the multiplicative inverse.

8. The number (y) = –1⅛ = –9/8

Multiplicative inverse (y¯¹) =?

y × y¯¹ = 1

–9/8 × y¯¹ = 1

Divide both side by –9/8

y¯¹ = 1 ÷ –9/8

y¯¹ = 1 × –8/9

y¯¹ = –8/9

Thus, 8/9 is not the multiplicative inverse of –1⅛

9. The number (y) = 3⅓ = 10/3

Multiplicative inverse (y¯¹) =?

y × y¯¹ = 1

10/3 × y¯¹ = 1

Divide both side by 10/3

y¯¹ = 1 ÷ 10/3

y¯¹ = 1 × 3/10

y¯¹ = 3/10

y¯¹ = 0.3

Thus, 0.3 is the multiplicative inverse of 3⅓.

Step-by-step explanation:

Given:

[tex]a_n=a_{n-1}+3[/tex]

[tex]a_0=2[/tex]

To find:

The values [tex]a_1,a_2,a_3[/tex].

Solution:

We have,

[tex]a_n=a_{n-1}+3[/tex]

For [tex]n=1[/tex],

[tex]a_1=a_{1-1}+3[/tex]

[tex]a_1=a_{0}+3[/tex]

[tex]a_1=2+3[/tex]

[tex]a_1=5[/tex]

For [tex]n=2[/tex],

[tex]a_2=a_{2-1}+3[/tex]

[tex]a_2=a_{1}+3[/tex]

[tex]a_2=5+3[/tex]

[tex]a_2=8[/tex]

For [tex]n=3[/tex],

[tex]a_3=a_{3-1}+3[/tex]

[tex]a_3=a_{2}+3[/tex]

[tex]a_3=8+3[/tex]

[tex]a_3=11[/tex]

Therefore, [tex]a_1=5,a_2=8,a_3=11[/tex].

The value of [tex]\rm a_1=5[/tex], [tex]\rm a_2=8[/tex], and [tex]\rm a_3=11[/tex] and this can be determined by using the arithmetic operations and the given data.

Given :

Let {an} be a sequence that satisfies the recurrence relation [tex]\rm a_n=a_{n-1}+3[/tex] for n = 1, 2, 3,... and suppose that [tex]\rm a_0=2[/tex].

According to the given data, the recurrence relation is given below:

[tex]\rm a_n=a_{n-1}+3[/tex]   --- (1)

Now, substitute the value of (n = 1) in the above expression.

[tex]\rm a_1=a_{1-1}+3[/tex]

[tex]\rm a_1=a_{0}+3[/tex]           (put [tex]\rm a_0=2[/tex])

[tex]\rm a_1=2+3[/tex]

[tex]\rm a_1=5[/tex]

Now, substitute the value of (n = 2) in the expression (1).

[tex]\rm a_2=a_{2-1}+3[/tex]

[tex]\rm a_2=a_{1}+3[/tex]           (put [tex]\rm a_1=5[/tex])

[tex]\rm a_2=5+3[/tex]

[tex]\rm a_2=8[/tex]

Now, substitute the value of (n = 3) in the expression (1).

[tex]\rm a_3=a_{3-1}+3[/tex]

[tex]\rm a_3=a_{2}+3[/tex]           (put [tex]\rm a_2=8[/tex])

[tex]\rm a_3=8+3[/tex]

[tex]\rm a_3=11[/tex]

The volume of a right circular cone has a height of 5.4 m and a base with a diameter of 5.1 m is 90.07 cubic meter.

Suppose that the radius of the considered right circular cone is 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
