Find 0.8% of 1,046 what is 0.8% of 1,046

Answers

Your correct answer should be 8.368

The required answer would be 8.368 which is 0.8 percent of 1,046.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For instance, If Mishali obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

We have to determine the evaluation of 0.8% of 1,046.

⇒ 0.8% of 1,046

0.8%  is expressed as 0.8/100 in fractional form

⇒ (0.8/100)(1,046)

0.8/100  is expressed as 0.008 in decimal form

⇒ (0.008 )(1,046)

Apply the multiplication operation, and we get

⇒ 8.368

Therefore, 0.8% of 1,046 would be 8.368.

1440 tons of grain were brought to a silo over two days. On the second day, 80% of the amount of the grain delivered during the first day was brought in. How many tons of grain were delivered to the silo on the first day?

Answers

Final answer:

To find out how many tons of grain were delivered on the first day, a simple algebraic equation was set up and solved to show that 800 tons were delivered on the first day.

Explanation:

Given that 1440 tons of grain were delivered to a silo over two days, we need to determine the amount delivered on the first day. It was stated that the second day's delivery was 80% of the first day's. Let's represent the first day's delivery as x tons. Therefore, the second day's delivery would be 0.80x tons. The sum of the two-day deliveries equals 1440 tons. This gives us the equation:

x + 0.80x = 1440

To solve this equation, we combine like terms:

1.80x = 1440

Dividing both sides by 1.80 gives us:

x = 1440 / 1.80

x = 800

Thus, 800 tons of grain were delivered on the first day.

Answers

Hi! To estimate you just have to average the probability of the computer game responding "go" when a button is pressed. For the first one, the button responded "go" 8 out of 10 times, which gives it a probability of 80%. For the second one, the probability is 32/50 or 64%, while the third one is 67/100 or 67%.

Averaging this we'll get:
[tex] \frac{0.80+0.64+0.67}{3} =0.70[/tex]

Since we're just estimating, we can choose the value closest to 70%.

Step-by-step explanation:

The number of taxi accidents is approximated by y equals negative 143.3 x squared plus 1823.3 x plus 6820 and the number of injuries is approximated by y equals negative 416.72 x squared plus 4416.7 x plus 8500. Let xequals0 represents​ 1990, xequals1 represents​ 1991, and so on.

Answers

Answer:
number of taxi accidents = 12235.2 which is approximately approximately 12235 accidents

Explanation:
The equation for the number of accidents is given as:
y = -143.3 x² +1823.3 x + 6820

We are given that:
x = 0 represents 1990
x = 1 represents 1991
Therefore:
x = 8 represents 1998

Now, all we have to do is substitute with the value of x = 8 in the equation of accidents to get the number of taxi accidents in 1998 as follows:
y = -143.3 (8)² +1823.3 (8) + 6820
y = -143.3 (64) + 1823.3 (8) + 6820
y = -9171.2 + 14586.4 + 6820
y = 12235.2

If we are asked to approximate the answer, then it would be approximately 12235 accidents

Please help on #8, Due really soon!!

Answers

Answer: 72 square centimeters

-------------------------------------------------------------

Area of triangle ECD = (base)*(height)/2
Area of triangle ECD = 6*12/2
Area of triangle ECD = 72/2
Area of triangle ECD = 36 square cm

Subtract this area from the trapezoid area. This will get us the area of the parallelogram

Area of Parallelogram ABCE = (area of trapezoid ABDE) - (area of triangle ECD)
Area of Parallelogram ABCE = (180) - (36)
Area of Parallelogram ABCE = 144 square cm

The last step is to divide the area of the parallelogram in half. This is because the parallelogram is made of two congruent triangles (triangle ABE and triangle EBC). The two triangles ABE and EBC have equal areas

Area of triangle EBC = (1/2)*(area of parallelogram ABCE)
Area of triangle EBC = (1/2)*(144)
Area of triangle EBC = 72 square centimeters

Answers

In this problem, you are asked to write a number in scientific notation. In figures, 78 million would look like this:

To write this to scientific notation, you have to move the decimal point to the left until you will get a number between 1 and 10.

Here, you will have to move the decimal point 7 times to get 7.8

The exponent of the scientific notation is the number of times you moved your decimal point. Since the movement of decimal point is going to the left, you will have a positive exponent.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

The sum of the angles = 180

So,

From the triangle,

3(x + 2) + 35 + 52 = 180

3x + 6 + 35 + 52 = 180

3x  + 93 = 180

3x = 180 - 93

3x = 87

x = 29

Now,

∠C = 3 (x + 2)

= 3 (29 + 2)

= 3 x 31

= 93

Thus,

The value of x is 29.

The measure of angle C is 93.

A sign says that the price marked on all music equipment is at a discount for 30% off. You buy an electric guitar for the same price of $315.
{Im only in 7th grade.}
What is the percent you pay? _____________
Write an equation to find the regular price of the item. __________________
What was the regular price? ____________

Answers

Hi there!

a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.

b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:

315/x = 70/100

This is because 315 is part of the whole and is 70% of the value of x.

How to solve it:

Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.
Final answer:

The percent paid after a 30% discount is 70% of the regular price. The equation to find the regular price is 0.70 * P = $315. Solving this gives us the regular price of the electric guitar, which is $450.

Explanation:

If a sign says that the price marked on all music equipment is at a discount for 30% off, and you buy an electric guitar for $315, we need to figure out the percent you actually pay and the regular price of the guitar.

Since the discount is 30%, you pay 100% - 30% = 70% of the regular price.

Let's call the regular price 'P'. The equation to find the regular price of the item after a 30% discount is:

0.70 * P = $315

To find the regular price 'P', we divide both sides of the equation by 0.70:

P = $315 / 0.70

P = $450

The regular price of the electric guitar before the discount was $450.

Jana is ordering a list of numbers from least to greatest.
Which statement can be used to create her list?
A) The square root of 0.8 is less than 4/5 because 0.8= 4/5 and the square root of a number less than 1 is less than the number itself.
B) The square root of 7 is greater than the square root of 7^2 because the square root of 7^2=7 and the square root of a number greater than 1 is greater than the number itself.
C) (The square root of 5)^2 is less than the square root of 7 because (The square root of 5)^2= 5 and the square root of 7 is between 6 and 8.
D) the square root of 7 is greater than 4/5 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.

Answers

Lets check the validity of each one of our statements:

Statement A is false.
The square root of a number less than 1 is greater than the number itself. In fact, [tex] \sqrt{ \frac{4}{5} } = \sqrt{0.8} =0.89[/tex]. Since [tex]0.89[/tex] is greater than [tex]0.8[/tex], [tex] \sqrt{0.8} [/tex] is greater than [tex] \frac{4}{5} [/tex]; therefore, statement A is false.

Statement B is false. The square root of a number greater than 1 is less than the number itself. in fact, [tex] \sqrt{7} =2.64[/tex], whereas [tex] \sqrt{7^2} =7[/tex]. Since 2.64 is less than 7, [tex] \sqrt{7} [/tex] is less than [tex] \sqrt{7^2} [/tex]; therefore statement B is false.

Statement C is false. [tex] \sqrt{7} [/tex] is actually less than 7 divided by two, so there is no way that [tex] \sqrt{7} [/tex] is between 6 and 8. In fact [tex] \sqrt{7} =2.64[/tex]. Since 5 is greater than 2.64, [tex]( \sqrt{5} )^2[/tex] is greater than [tex] \sqrt{7} [/tex]; therefore, statement C is false.

Statement D is true. [tex] \sqrt{7} =2.64[/tex]. Since 2.64 is greater than 0.8, [tex] \sqrt{7} [/tex] is greater than [tex] \frac{4}{5} [/tex].

We can conclude that Jana should use statement D to create her list; also the correct order from least to greatest is: [tex] \frac{4}{5} [/tex], [tex] \sqrt{0.8} [/tex],[tex] \sqrt{7} [/tex], [tex]( \sqrt{5} )^2[/tex], [tex] \sqrt{7^2} [/tex]
