please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
A) 40
B) 20
Step-by-step explanation:
By Length · Width · Height
A) (5) · (4) · (2) = 40
For part B, the length and width are the same, but the depth (height) of the water is only one foot, so we can replace the height value from the first equation with 1.
B) (5) · (4) · (1) = 20
A television is on sale for 30% off. The sale price is $322. What is the original price of the television?
PLEASE HELP QUICK
Answer:
$460
Step-by-step explanation:
Let
x = original price of the television
Sale price = $322
Discount = 30%
x - 30% of x = 322
x - 0.3 * x = 322
x - 0.3x = 322
0.7x =322
x = 322/0.7
x = $460
x = original price of the television = $460

Answer:
1.75 liters
Step-by-step explanation:
Multiply 50ml per set by 35 sets to get 1750ml. If 1000 ml is 1 liter, then 1750 ml is 1.75 liters. :)

Step-by-step explanation:
if y=12 and x=89, then what is the value of z?
Answer:
z = 166°
Step-by-step explanation:
Given:
x = 89
y = 12
An angle with its vertex in a circle = ½(intercepted arcs)
Thus:
x = ½(y + z)
Substitute
89 = ½(12 + z)
Multiply both sides by 2
2(89) = 12 + z
178 = 12 + z
178 - 12 = z
z = 166°

A field researcher is gathering data on the trunk diameters of mature pine and spruce trees in a certain area. The following are the results of his random sampling: Pine Trees Spruce Trees Sample Size 40 80 Mean trunk diameter (cm) 35 30 Population variance 160 160 Using a .10 significance level, can he conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree
Answer:
As the pvalue of the test is 0.02097 < 0.1, using a .10 significance level, he can conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree.
Step-by-step explanation:
Using a .10 significance level, can he conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree
The null hypothesis is that they are equal(that is, subtraction between the means is 0), while the alternate hypothesis is that they are greater(that is, subtraction between the means is larger than 0). So
[tex]H_0: \mu_1 - \mu_2 = 0[/tex]
[tex]H_a: \mu_1 - \mu_2 > 0[/tex]
In which [tex]\mu_1[/tex] is the mean pine trees height while [tex]\mu_2[/tex] is the mean spruce trees height.
The test statistic is:
[tex]z = \frac{X - \mu}{s}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis and s is the standard error.
0 is tested at the null hypothesis:
This means that [tex]\mu = 0[/tex]
Mean trunk diameter (cm) 35 30:
Pine trees - 35
Spruce trees - 30
The sample mean is given by the subtraction of the means. So
[tex]X = 35 - 30 = 5[/tex]
Sample Size 40 80
Population variance 160 160
This means that the standard error for each sample is given by:
[tex]s_1 = \frac{\sqrt{160}}{\sqrt{40}} = 2[/tex]
[tex]s_1 = \frac{\sqrt{160}}{\sqrt{80}} = \sqrt{2}[/tex]
The standard error of the difference is the square root of the sum squared of the standard error of each sample.
[tex]s = \sqrt{2^2 + (\sqrt{2})^2} = \sqrt{6} = 2.4495[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{s}[/tex]
[tex]z = \frac{5 - 0}{2.4495}[/tex]
[tex]z = 2.04[/tex]
Pvalue of the test:
Probability of a sample mean larger than 5, which is 1 subtracted by the pvalue of Z when X = 5.
Looking at the z-table, z = 2.04 has a pvalue of 0.9793.
1 - 0.9793 = 0.0207
As the pvalue of the test is 0.02097 < 0.1, using a .10 significance level, he can conclude that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree.

Activists say that the Brazilian government is not doing enough to stop the destruction of the Amazon rain forest. In 2004, the government reported the second-highest rate of destruction ever. Brazil's government estimates that farmers cut down 10,590 square miles (27,430 square kilometers) of rain forest. That is an area larger than Vermont, and it shows an increase from the deforestation of the previous year. In fact, the 2004 figure is nearly that of 1995, in which the Amazon lost a record 11,229 square miles (29,080 square kilometers) of trees. The activists are demanding that officials take the problem more seriously. Do It! The rain forest destruction seems to be _________.

how do you find the percent of discount if the original price is $578 and the sale price is $78.76
Answer: 86%discount approx
Step-by-step explanation:
You need to think about how the original price (578) is 100% of the price and that the sale price (78) is just a percentage of that. To discover how much of that 100% the price 78 is, you can write the formula:
578:100=78:x
X=(78*100)/578
X=14 %
Once you know that 78 represents the 14% of the whole price (100%-578) you just have to subtract that amount from the whole to understand which percent of discount has been applied: 100-14 = 86%

The height of a triangle is 5 more than double the base length. If the height of the triangle is 74mm, what is the base length of the triangle
Answer:
height = 5+2xbase
74 = 5+2xbase
subtract 5 from both sides
69 = 2xbase
divide both sides by 2
34.5mm = base length

A concrete pilar has the shape of a svinder It has a diameter of 6 meters and a height of 5 meters. If concrete costs $108 per cubic meter, how much did the
concrete cost for the pillar?
If necessary, refer to the list of cometry formulas
For your calculations, do not round any intermediate stops, and use the it button on the ALEKS calculator Round your answer to the nearest cent.
Answer:
The cost of concrete for the pillar would be $ 15,260.40.
Step-by-step explanation:
Given that a concrete pillar has the shape of a cylinder and it has a diameter of 6 meters and a height of 5 meters, if concrete costs $ 108 per cubic meter, to determine how much did the concrete cost for the pillar the following calculation must be done, knowing that the volume of a cylinder is calculated with the following formula = πxr²xh:
3.14 x (6/2) ² x 5 = X
3.14 x 3² x 5 = X
3.14 x 9 x 5 = X
3.14 x 45 = X
141.3 = X
141.3 x 108 = X
15,260.4 = X
Therefore, the cost of concrete for the pillar would be $ 15,260.40.
