Answer:

10 tragic and histories, and 1y comedies

Step-by-step explanation:

let X = the number of tragedies

let X = the number of histories

2x - 3 = the number of comedies

x + x + 2x - 3 = 37

4x = 40

x = 10

2x - 3 = 2(10) - 3 = 17 comedies.

(7 hot dogs)/(4 minutes) = (23 hot dogs)/(x minutes)

7/4 = 23/x

7x = 4*23 .... cross multiplication

7x = 92

x = 92/7

x = 13.142857 approximately

x = 13.1

Answer:

point a is start with positive but point b start with negative

It is observed that point (18, 206) does not lie on the line. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation is given below.

y = 12x

Where 'y' represents the number of gallons of water in the pool and 'x' represents the number of minutes the water runs.

The equation is drawn below.

From the chart, it is seen that point (18, 206) doesn't lie on the line. Then the right choice is D.

Answer:

15/20

Step-by-step explanation:

Divide your denominator by your previous/compared denominator (20/8) to find the number as your numerator. Take the found numerator (2.5) and multiply it times the compared numerator (2.5 x 6) giving your 15/20.

Answer:

25/15 > 24/18

Step-by-step explanation: Both of these fractions can be reduced so that the denominator is 3. This will make it much easier to compare the two fractions. For 24/18, if you divide both the numerator and the denominator by 6, then the fraction simplifies to 4/3. For 25/15, if you divide the numerator and denominator by 5, then the fraction simplifies to 5/3. Since these fractions have a common denominator, the fraction with the larger numerator is going to be the larger fraction. So, 25/15 is greater than 24/18.

Answer:

year 6

Step-by-step explanation:

she will be at 48,000

the other girl will be at 46,000

The year in which the salary Sharon's first exceeds Samantha's salary if,  is the 5th year Sharon graduates from college, she accepts a job that pays $30,000 for the is 5 years.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

Sharon's pay = $30000,

Raise percentage = 10%,

Samantha pays = $40000,

Raise by  = $1000,

Calculate Sharon's pay as shown below,

Sharon's pay  = 30000(1 + 0.10)⁴

Sharon's pay  = 30000 × 1.77

Sharon's pay  = $43923

Calculate pay of Samantha after 4 years,

The pay of Samantha = 40000 + 4 × 1000

The pay of Samantha = $44000

Thus, Sharon's annual salary first exceeds Samantha's after 4 years.

9514 1404 393

Answer:

  ∠A = 44°

Step-by-step explanation:

In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.

Happily, that relation is "the sum of angles in a triangle is 180°." This means ...

  84° +(x +59)° +(x +51)° = 180°

  (2x + 194)° = 180° . . . collect terms

  2x = -14 . . . . . . . . . . divide by °, and subtract 194

  x = -7 . . . . . . . . . . . .divide by 2

Now, the measure of angle A is ...

  ∠A = (x +51)° = (-7 +51)°

  ∠A = 44°

The graph D has a x-intercept = −1  and y-intercept = 5

The given parameters are:

x-intercept = −1

y-intercept = 5

The above means that the graph crosses the x-axis at -1, and it crosses the y-axis at -5

From the list of options, the graph that satisfies the above highlights is graph D

Hence, the graph D has a x-intercept = −1  and y-intercept = 5

Using polar/cylindrical coordinates, we take

x = r cos(t )

y = r sin(t )

z = z

so that

dV = dx dy dz = r dr dt dz

The solid is given by the set

D = {(x, y, z) : x ² + y ² ≤ 1 and 0 ≤ z ≤ 4 - 2x - y}

or in cylindrical coordinates,

D = {(r, t, z) : 0 ≤ r ≤ 1, 0 ≤ t ≤ 2π, and 0 ≤ z ≤ 4 - 2r cos(t ) - r sin(t )}

Then the volume of the solid is

[tex]\displaystyle \iiint_D \mathrm dV = \iiint_Dr\,\mathrm dr\,\mathrm dt\,\mathrm dz \\\\ = \int_0^{2\pi} \int_0^1 \int_0^{4-2r\cos(t)-r\sin(t)} r\,\mathrm dz\,\mathrm dr\,\mathrm d t \\\\ = \int_0^{2\pi}\int_0^1 (4r-2r^2\cos(t)-r^2\sin(t))\,\mathrm dr\,\mathrm dt \\\\ = \int_0^{2\pi} \left(2 - \frac23 \cos(t) - \frac13 \sin(t)\right) \,\mathrm dt \\\\ = \boxed{4\pi}[/tex]

The volume of the given solid below the plane 2x + y + z = 4 and above the disk x2 + y2 ≤ 1 is 4π.

The volume of the solid in polar coordinates can be calculated by the double integral in polar coordinates.

[tex]V = \iint_R f(x,y) \,dA.\\[/tex]

Similarly, by polar coordinates,

x = r cost

y = r sint

z = z

we get, dV = dx dy dz = r dr dt dz

The solid is given

D = {(x, y, z) : x ² + y ² ≤ 1 and 0 ≤ z ≤ 4 - 2x - y}

or in polar coordinates,

D = {(r, t, z) : 0 ≤ r ≤ 1, 0 ≤ t ≤ 2π, and 0 ≤ z ≤ 4 - 2r cos(t ) - r sin(t )}

The volume of the solid is

[tex]\rm \int \int\int\ dV = \int \int\int\ rdr dt dz\\ \rm = \int\limits^{2\pi}_0\int\limits^1_0 \int\limits^{4-2rcost-rsint}_0 rdr dt dz\\\rm =\int\limits^{2\pi}_0\int\limits^1_0 {4r-2r^{2} cost-r^{2} sint} dr dt\\\rm =\int\limits^{2\pi}_0( 2-2/3cost-1/3sint) dt\\\rm =4\pi[/tex]
