What is the value of 4 + 5x when x = 3?

A: 11
B:12
C:17
D:19

Answer:

Step-by-step explanation:

first use tan Ф = opp /adj      to find x         tan(30) = √3 / 3

then use sin Ф = opp / hyp   to find y         sin(30) = 1/2

       tan(30) = (√3) / 3  =  x / 48

                           x = (48√3) / 3

                          x = 16√3

        sin(30) = 1/2  = x / y

                        y  =  x / (1/2)

                        y  =  2x        x = 16√3

                        y  =  2[16√3]

                        y  =  32√3

check  using      a² + b²  = c²

             x² + 48² = y²

            (16√3)² + 48² = (32√3)²

           256 · 3  + 2304  =  1024 · 3

           768   +  2304   =   3072

                         3072  =  3072

Answer:

The numerical limits for a D grade are 58(lower limit) and 61(upper limit).

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.

Scores on the test are normally distributed with a mean of 67.3 and a standard deviation of 7.3.

This means that [tex]\mu = 67.3, \sigma = 7.3[/tex]

D: Scores below the top 80% and above the bottom 9%

This means that lower bound is the 9th percentile and the upper bound is the 100 - 80 = 20th percentile.

9th percentile:

This is X when Z has a pvalue of 0.09. So X when Z = -1.34.

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

[tex]-1.34 = \frac{X - 67.3}{7.3}[/tex]

[tex]X - 67.3 = -1.34*7.3[/tex]

[tex]X = 57.52[/tex]

Rounding to the nearest whole number, 58.

20th percentile:

This is X when Z has a pvalue of 0.2. So X when Z = -0.84

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

[tex]-0.84 = \frac{X - 67.3}{7.3}[/tex]

[tex]X - 67.3 = -0.84*7.3[/tex]

[tex]X = 61.17[/tex]

Rounding to the nearest whole number, 61.

The numerical limits for a D grade are 58(lower limit) and 61(upper limit).

Step-by-step explanation:

Dimensions of cube = 1 in × 1in .

No. of cubes in each layer = 15 .

No. of layers = 2 .

• Therefore the volume of one cube :-

[tex]\tt \to Volume_{(cube)}= side^3 = (1 \ in.)^3 = \red{1in.^3}[/tex]

• Therefore the volume of one layer :-

[tex]\tt\to 1\ in.^3\times 15 =\orange{15\ in.^3} [/tex]

• Therefore the volume of whole box :-

[tex]\tt\to 2\ in.^3\times 15 =\orange{30\ in.^3} [/tex]

Therefore our required answer is 30 inch ³.

15x2=30 polegadas

Answer:

14 units.

Step-by-step explanation:

Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.

P = 2(l + w)

P = 2(3 + 4)

P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)

P = 14 units and 14 units.

You could also do addition.

P = 3 + 3 + 4 + 4

P = 6 + 8

P = 14 units

Answer:

The x-intercepts are 1 and 3

The y-intercept is 3

The vertex is (2,-1)

The line of symmetry is x=2

Step-by-step explanation:

To find the x-intercepts, find where the graph intersects the x-axis, or the horizontal line. To find the y-intercept, find where the graph intersects the y-axis, or the vertical line. To find the vertex, find the coordinate where the graph is at its lowest point (or highest if it is flipped upside down). To find the line of symmetry, simple use the x-coordinate of the vertex and say x= (the x-coordinate)

Answer:

[tex]x = 19[/tex]

[tex]y = 22.5[/tex]

Step-by-step explanation:

[tex]5y + 3y = 180[/tex]

[tex]8y = 180[/tex]

[tex]y = 22.5[/tex]

[tex]6x + 13 + 4x - 3 = 180[/tex]

[tex]10x - 10 = 180[/tex]

[tex]10x = 190[/tex]

[tex]x = 19[/tex]

Answer:

Lateral area of the cylinder = 62.85 cm²

Step-by-step explanation:

Given:

Diameter of cylinder = 10 cm

Radius of cylinder = 10 / 2 = 5 cm

Height of cylinder = 2 cm

Find:

Lateral area of the cylinder

Computation:

Lateral area of the cylinder = 2πrh

Lateral area of the cylinder = 2(22/7)(5)(2)

Lateral area of the cylinder = 2(22/7)(10)

Lateral area of the cylinder = (440/7)

Lateral area of the cylinder = 62.85 cm²

Answer:

15cookies

Step-by-step explanation:

Complete question:

Mrs Tay baked 45 cookies. She gave 1/3 of them to her friends. How many cookies did she give her friends?

Given the following

Total cookies = 45 cookies

Fraction of cookies given = 1/3

Amount she gave her friends= 1/3 * 45

Amount she gave her friends= 45/3

Amount she gave her friends= 15cookies

Hence she gave 15cookies to her friends

Answer:

15n

Step-by-step explanation:

Given

The above table

Required

The formula of the table

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{n_2 - n_1}[/tex]

Where:

n = Number of Lawns

y = Earnings

[tex](n_1,y_1) = (2,30)[/tex]

[tex](n_2,y_2) = (5,75)[/tex]

So, we have:

[tex]m = \frac{75 - 30}{5 - 2}[/tex]

[tex]m = \frac{45}{3}[/tex]

[tex]m = 15[/tex]

The equation is then calculated as:

[tex]y = m(n- n_1) + y_1[/tex]

This gives:

[tex]y = 15(n- 2) + 30[/tex]

[tex]y = 15n- 30 + 30[/tex]

[tex]y = 15n[/tex]

Hence:
