A piece of land was purchased for $65,000. The value of the land has slowly been decreasing by 1% annually. What will the land be worth in 20 years?

Answer:

E and X

Step-by-step explanation:

look for the 6 then behind it

Answer:

X and E

Step-by-step explanation:

"axes" is the plural of axis. The x-axis is the flat line marked with numbers and arrows at the ends. Its labelled x on the right side.

The y-axis is the up-and-down line marked with numbers and arrows at the ends, labelled y at the top.

The origin is where the two axes cross.

Points J, E, X and P are all on the axes. But X and E are 5 units from the origin (where the lines cross) J and P are 9 units from the origin.

2, 6 and 10 were labelled on the axes, but each tick mark is an evenly spaced amount. So the 5 was unlabelled, but it is understood to be 5. See image.

The value of g after solving the expression, 5/2-2g = 5g/2-3+g, is 1.

According to the question,

We have the following expression:

5/2-2g = 5g/2-3+g

Now, moving the terms with the same variables on one side and the integers on another side.

Note that when we move any number of term from one side to another which is in addition or subtraction will result in change of the sign from minus to plus and plus to minus.

5/2+3 = 2g+5g/2+g

Taking 2 as the least common factor on the left hand side and right hand side:

(5+6)/2 = (4g+2g+5g)/2

11/2 = 11g/2

Now, 11/2 on the left hand side can be divided by 11/2 on the right hand side:

g = 1

Hence, the value of g is 1.

The 50 pounds of trail mix includes 28.57 pounds of cashews and 21.43 pounds of chocolate candies.

let

x + y = 50

2.75x + y = 50 × 2

Solve the equation simultaneously

x + y = 50

2.75x + y = 100

2.75x - x = 100 - 50

1.75x = 50

x = 50/1.75

x = 28.57 pounds

Substitute into

x + y = 50

28.57 + y = 50

y = 50 + 28.57

y = 21.43 pounds

So therefore, the pounds of cashew and chocolate candies needed are 28.75 and 21.43 respectively.

The crate's density in pounds per cubic foot?

Since the crate of medicine with a density of 2050 kilograms per cubic meter will be shipped from England to the U.S, we require its density in pounds per cubic foot.

To do this, we convert the density in kilograms per cubic foot to pounds per cubic foot by using the ratios of conversion given

Since the density of the crate in kilograms per cubic meter is

2050 kg/m³, using the conversion ratios, we have

2050 kg/m³ = 2050 kg/m³ × 1 m³/35.3 ft³ × 2.2 lb/kg

= 4510 lb/m³ × 1 m³/35.3 ft³

= 127.76 lb/ft³

The measure of side AC in the triangle is 2.7 m

From the question, we are to determine the measure of AC

From the given information, we have that ΔADC is similar to ΔCDB

Thus,

We can write that

|DC| / |DB| = |AC| / |CB|

From the diagram,

|DC| = 5.5 m

|DB| = 6.3 m

|AC| = h

|CB| = 3.1 m

Then,

5.5 / 6.3 = h / 3.1

∴ h = (5.5 × 3.1) / 6.3

h = 17.05 / 6.3

h = 2.70635 m

h ≈ 2.7 m

Hence,

The length of AC is 2.7 m

Answer: 3.28 inches

Step-by-step explanation:

Fabric used for players and coaches is 776.32 inches.

Number of players is 29 and coaches is 3

So fabric used for each player and coach for the headbands is

776.32/29+3 = 24.26 inches

So, for the players 24.26 of fabric will be used for the headbands.

Total fabric used for the wristbands is 247.66 inches

Fabric used for the wristband is

247.66/29 = 8.54 inches

So, total amount of fabric used by Shelia for the wristband and headband is 24.26 + 8.54 = 32.8 inches.

The y-intercept of the line will be equal to 7.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that a line that has a slope of 2 and ( - 2, 3 ). The y-intercept of the line will be calculated as,

y = mx + c

3 = (-2 x 2 ) +c

3 = -4 + c

c = 4 + 3

c = 7

At the 1% level of significance, the heat shield for the Komodo spacecraft have average temperature of 191.811° C < x-bar < 196.73° C which is less 200◦C

Type I error is explained below

1% level of significance means that the p value or the probability of the temperature of the new heat shield for Komodo spacecraft being less than 200° C is less than 1%

The range of average temperatures of the shield is given by the formula

= x-bar ± t(s/√n)

Definition of variables

mean, x-bar = 194.37° C

standard deviation, s = 4.29° C

sample size, n = 24

significance level = 1%

confidence level = 1 - significance level = 1 -  0.01 = 0.99 = 99%

z score, z

For sample size less than 30, n < 30. t scores are used

degree of freedom, df = n - 1 = 24 - 1 =23

t score for 99% confidence level and df of 23 = 2.808

substituting into the formula

= x-bar ± t(s/√n)

= 194.37 ± 2.808 (4.29/ √24)
