Answer:
8 square inches
Step-by-step explanation:
The area is the number of square inches a shape covers. To find the area of a triangle use the formula A = 1/2 b*h. Here b = 4 and h = 4.
So the area is A = 1/2 4*4 = 8 square inches

Answers
Answer:
6
Step-by-step explanation:
f (x)=x^2and g(x)=x+6 (I will assume you meant x not c)
The first step if to find f(0)
f(0) = 0^2 = 0
Now we find g(f(0))= g(0)
g(0) = 0+6 = 6
g(f(0) =6
If you meant c

The scores of eighth-grade students in a math test are normally distributed with a mean of 57.5 and a standard deviation of 6.5. From this data, we can conclude that 68% of the students received scores between
Answers
Answer:
51 and 64
Step-by-step explanation:
The Empirical Rule states that 68% of normally distributed data lies within one standard deviation of the mean.
Hence, if the mean is 57.5, one standard dev. above that is 57.5+6.5, or 64, and one standard dev. below the mean is 57.5-6.5 = 51.
Thus,
we can conclude that 68% of the students received scores between 51 and 64.
Final answer:
Approximately 68% of the eighth-grade students received scores between 51 and 64.
Explanation:
In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. So, in this case, 68% of the eighth-grade students received scores between the mean of 57.5 minus one standard deviation of 6.5 and the mean plus one standard deviation.
Calculating the range:
57.5 - 6.5 = 5157.5 + 6.5 = 64Therefore, we can conclude that approximately 68% of the students received scores between 51 and 64.
Find the radius of the circle whose equation is x² + y² = 4.
Answers
Answer:
Radius : 2
Step-by-step explanation:
Rewrite in standard form to find the radius.
Hope this helps,
Davinia.
The radius of the circle with the equation x² + y² = 4 is 2 units, calculated by taking the square root of the right-hand side of the equation.
The question requires us to find the radius of a circle given its equation. The standard form of a circle's equation is (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. The given equation, x² + y² = 4, indicates that the circle is centered at the origin (0,0) and the radius is the square root of 4.
To calculate the radius, we take the square root of 4:
r = √4 = 2.
Therefore, the radius of the circle is 2 units.

Quincy feeds his dog 2.75 cups food each day each cup of dog food costs $1.25. He multiplies the numbers together to determine how much it costs to feed his dog each day. Which expression will result in the best estimate for Quincy to use to check his multiplication?
Answers
2times1 because 2.75 take the 75 off and 1.25 take the 25 off so you multiply 2 and 1 so 2times1 equals 2
Answer:
C) 3 x 1
Step-by-step explanation:
First, you round 2.75 to 3 because of the rounding rule- "If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up." Then you round 1.25 to 1 because of the rounding rule. Then you get 3 x 1!

Jen slices a cone with a height of 10 centimeters and a radius of 4 centimeters using a plane that is perpendicular to the base and that passes through the vertex of the cone. What is the area of the cross-section in square centimeters?
Answers
Answer: [tex]40cm^2[/tex]
Step-by-step explanation:
A cross-section is the shape that results of the intersection of a plane with an abject.
When the cone is sliced by a plane perpendicular to the base and passes through the vertex, the cross-section obtained is a triangle.
The area of the triangle can be calculated with the formula:
[tex]A=\frac{b*h}{2}[/tex]
Where the base of the triangle is b and its height is h.
The base of the triangle is the diameter of the cone. Knowing the radius, the diameter is:
[tex]diameter=2*radius\\diameter=2*4cm\\diameter=8cm[/tex]
Then:
[tex]b=8cm[/tex]
The height ot this triangle is the height of the cone:
[tex]h=10cm[/tex]
So, by substituting into the formula you get the area of the cross-section in square centimeters:
[tex]A=\frac{(8cm)(10cm)}{2})=40cm^2[/tex]

B. 800 Joules
C. 100 Joules
D. 200 Joules
Answers
The mechanical energy will be 100 Joules
Step-by-step explanation:Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
So
Mechanical energy = 60J + 40J
Mechanical energy = 100 Joules
Answer:
The correct answer option is C. 100 Joules.
Step-by-step explanation:
We are given that Greta jumps up 2 feet into the air. Her potential energy is 60 Joules while her kinetic energy is 40 Joules.
We are to calculate her total mechanical energy which will be the sum of her potential energy and her kinetic energy.
So we simply need to add the two given values of the energies.
Total mechanical energy = 60 + 40 = 100 Joules

How do I solve this complicated problem?
Answers
Since all the sides of triangle ABE are congruent, all its angles are congruent, and since the angles of a triangle add to 180, this means that each of the angles in ABE must be 60 degrees (since 60 + 60 + 60 = 180).
The other triangle of notice in the problem is triangle ABC. Notice that, since it’s formed from a square, it’s a *right* triangle. This means that one of its angles must be 90. Sharing two sides with the square ABCD also means that two of the triangle’s sides are congruent, which *also* means the two non-right angles must be congruent. This forces them to be 45 degrees (since 90 + 45 + 45 = 180).
Now, take a look at angle EAC. That small angle is what we end up with if we take angle EAB (an angle of triangle ABE) and subtract angle CAB (part of triangle ABC) from it. EAB measures 60 degrees, and CAB measures 45, so angle EAB must be 60 - 45 = 15 degrees.
At this point, we’re almost done. I want to bring your attention to the point where line segments EB and AC intersect; let’s call that point F. If we want to find the measure of x, we can look at the angle right across from it, angle AFE. Notice that this angle is one of three in the triangle AFE. We’ve already found the other two, actually: angle AEF is 60 degrees, and angle EAF is 15, so to find AFE, we can simply subtract those two from 180 to find a measure of
180 - 60 - 15 = 180 - 75 = 105 degrees.
And since AFE and x are vertical angles, we know x must also be 105 degrees.

One bad has 3 1/4 cups remaining and the other bag has 6 1/8 cups remaining. How many cups of confectioners sugar Suze have left after she prepares her pies?
Answers
Answer:
1 7/8 cups leftover
Step-by-step explanation:
The total amt. of sugar Suze needs is 5(1 1/2 cups) = 15/2 cups, or 7.5 cups.
Combining the 3 1/4 and 6 1/8 cups of sugar remaining in the bag results in 3 2/8 + 6 1/8 cups, or 9 3/8 cups total. She needs only 7.5 cups of this sugar.
Thus, she has leftover the following amount: 9 3/8 - 7 4/8 cups, which
simplifies to 1 7/8 cups
