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?
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.
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.

The question in English is
Calculate the circumference of the circle entered in a square 8 cm long
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
where
D is the diameter of the circle
In this problem we have that
the diameter of the circle is equal to the length of the square
so
[tex]D=8\ cm[/tex]
Find the circumference
[tex]C=8\pi\ cm=25.13\ cm [/tex]
therefore
the answer is
The circumference of a circle is equal to [tex]8\pi\ cm\ or\ 25.13\ cm[/tex]

Mr. Green teaches band, choir, and math. This year, he has 57 students that take at least one of his classes. He teaches band to 25 students. There are 9 students who have Mr. Green for math and nothing else. Use the Venn diagram below:
How many students take exactly 2 classes with Mr. Green?
i need help with this
Answer:
Step-by-step explanation:
Given that Mr. Green teaches band, choir and math.
Total students = 57
Students who learn band A = 25
Students who learn math alone =9
From venn diagram we see that
band alone 11
choir alone 17
band and choir alone 4
band and math alone 7
math and choir alone 6
band choir and math 3
math alone 9 from 11+4+10+6+17 + M = 57
so
2 classes = 4+7+6 = 17
17 students take exactly two classes with Mr. Green

What are the coordinates of the vertex of the graph? Is it a maximum or minimum
Based on the graph, the coordinates of the vertex are at (0, -1), and since the parabola opens upwards, the vertex is a minimum.
Therefore, the correct answer is A:
(0,-1) ; minimum
The image shows a parabola opening upwards on a coordinate plane. The vertex of a parabola is the highest or lowest point on the graph, depending on whether the parabola opens downward or upward, respectively.
Here's a detailed explanation for identifying the vertex and determining if it is a maximum or minimum:
Step 1: Identify the Vertex
The vertex of a parabola in the form [tex]\(y = ax^2 + bx + c\)[/tex] can be found using the vertex formula [tex]\(x = -\frac{b}{2a}\)[/tex] for the x-coordinate and then substituting that back into the equation for y to find the y-coordinate. However, in this case, we can directly observe the vertex from the graph. It's the point where the parabola changes direction.
Step 2: Read the Coordinates from the Graph
From the graph, we can see that the vertex is at the origin of the parabola's turning point. It appears to be at (0, -1) by looking at where the axis of symmetry of the parabola intersects the y-axis.
Step 3: Determine Maximum or Minimum
Since the parabola opens upwards, as indicated by the shape of the graph, the vertex represents the minimum point of the parabola. If the parabola were to open downwards, the vertex would represent the maximum point.

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

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? ____________
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.

The value of x is 29.

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.
