The segment shown below could form a triangle. 6, 5, 8
AC 6 , CB 5, BA 8
Answer:
Yes
Step-by-step explanation:
In order to form a triangle sum of the lengths of any two sides must always be greater than the length of the third side.
Here,
6 + 5 = 11 > 8
5 + 8 = 13 > 6
8 + 6 = 14 > 5
Given side lengths satisfy above condition. Hence the given segment can form a triangle.
After entering the table values in his calculator, Cory used the LinReg button
to get the results shown. Identify the correlation coefficient and the type of
correlation.
Answer:
Strong positive correlation, 0.9663
Step-by-step explanation:
The value of the correlation coefficient will be; -0.2985, and the relation between x and y is a weak negative.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
The value of the correlation coefficient can be found as;
r = -0.2984713607
After rounding off we get;
r = -0.2985
As the value of r is not close to the -1 therefore, the relation between x and y is weak negative.
Hence, the value of the correlation coefficient will be; -0.2985, and the relation between x and y is a weak negative.

For the graph, what is a reasonable constraint so that the function is at least 200? graph of y equals minus 2 times the square of x plus 30 times x plus 200 −5 ≤ x ≤ 20 0 ≤ x ≤ 15 x ≥ 0 All real numbers
Answer:
The correct constraint is:
0 ≤ x ≤ 15
Step-by-step explanation:
The function given to us in the question is:
y = -2x² + 30x + 200
It is given that the function is at least 200, we can write is as:
-2x² + 30x + 200 ≥ 200 ⇒ Equation (i)
To find the constraint, replace ≥ sign with = sign and solve for x:
-2x² + 30x + 200 = 200
-2x² + 30x = 0
x(-2x + 30) =0
x = 0 , -2x + 30 = 0
x = 0 , -2x = -30
x = 0 , x = -30/-2
x = 0 , x = 15
So the end values of constraint are 0 and 15.
Take any value between 0 and 15 and substitute in equation (i) to see whether it satisfies the equation or not.
-2x² + 30x + 200 ≥ 200
Substitute x = 5 in the equation:
-2(5)² + 30(5) +200 ≥ 200
-50 + 120 +200 ≥ 200
270 ≥ 200
As the equation satisfies. it means that the solution lies between 0 and 15, including the end values.
Hence.
0 ≤ x ≤ 15

0 ≤ x ≤ 15

a. Which of these could be the area of Circle B? *
About 100 in ^2
About 300 in^2
About 900 in^2
About 2,700 in^2
b. Explain your reasoning for part a. Use the approximation of about 3 for pi. *
Answer:
D) About 2,700 in^2
Step-by-step explanation:
Equation for area of a circle is A=3r² (it would usually be A=πr² but we are using the approximation)
The diameter is 60, we want to find the radius for the equation. We can use the equation d=2r to find the radius of the circle.
60=2r
30=r
Put radius into the area equation.
A=3(30)²
A=3(900)
A=2700
Answer:
2,700 in^2 ; Option D
Step-by-step explanation:
If it is known that the diameter of Circle B ⇒ 60 inches,
[tex]Diameter - 60 inches,\\\\Radius - 60 / 2 = 30 inches,\\\\Area of Circle B ( \pi stands for 3 ) - \pi * ( r )^2 = ( 3 ) * ( 30 )^2 = ( About ) 2,700 square inches\\\\Solution; 2,700 square inches[/tex]
( About ) 2,700 square inches; Option D
At the end of a year, the gross debt of a country stood at about $24 trillion. Express this amount in dollars per person, assuming that the population of the country is about 298 million
Answer: $80536.9
Step-by-step explanation:
From the question, at the end of a year, the total debt of a country stood at about $24 trillion and the country has a population of 298 million.
To calculate the amount in dollars per person, we divide the gross debt by the population. This will be:
= 24 trillion ÷ 298 million
= 24,000,000,000,000 ÷ 298 000 000
= 80536.9
The amount in dollar per person will be $80536.9

A tree house is 10 feet up in a tree. A ladder that leans against the tree and
leads to the tree house door is 12 feet long. How far away from the base of
the tree is the bottom of the ladder? Draw a picture and solve. Round your
answer to the nearest tenth.
Answer:
6.63 ft
Step-by-step explanation:
In this case we use pythagora's theorem which is
[tex]hyp^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]opp^{2}[/tex]
in this case, the hypotenuse (hyp) is the length of the ladder, the opposite (opp) is the height of the tree house and, the adjacent (adj) is the distance of the ladder's bottom to the base of the tree.
hpy = 12 ft
opp = 10 ft
adj = ?
substituting into the equation above, we have
[tex]12^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]10^{2}[/tex]
144 = [tex]adj^{2}[/tex] + 100
144 - 100 = 44 = [tex]adj^{2}[/tex]
the image is shown below
adj = [tex]\sqrt{44}[/tex] = 6.63 ft

Concrete is made by mixing cement, sand, and
gravel in the ratio 5:9:13. How much cement
is nceded to make 324 ft of concrete?
Answer:
60
Step-by-step explanation:
Sum the parts of the ratio, 5 + 9 + 13 = 27 parts
Divide the amount of concrete by 27 to find the value of one part of the ratio.
324 ÷ 27 = 12 ← value of 1 part of the ratio , thus
5 parts = 5 × 12 = 60 ← cement
9 parts = 9 × 12 = 108 ← sand
13 parts = 13 × 12 = 156 ← gravel
To make 324 ft of concrete, we would need 60 ft of cement.
We have,
Given the ratio of cement, sand, and gravel as 5:9:13, we can consider the total number of parts in the mixture as 5 + 9 + 13 = 27 parts.
Now,
27 parts = 324 ft
Divide both sides with 27.
1 part = 324/27 ft
1 part = 12 ft
Now,
1 part = 12 ft
Multiply 5 on both sides.
5 parts = 5 x 12 ft
5 parts = 60 ft
Therefore,
To make 324 ft of concrete, we would need 60 ft of cement.

Here is the base of a prism.
a. If the height of the prism is 5 cm, what is its surface area? What is its volume?
b. If the height of the prism is 10 cm, what is its surface area? What is its volume?
c. When the height doubled, what was the percent increase for the surface area? For the volume?
Answer:
A). Surface area = 222 cm²
Volume = 180 cm³
B). Surface area = 375 cm²
Volume = 360 cm³
C). % increase in surface area = 67.57%
% increase in volume = 100%
Step-by-step explanation:
In the figure attached base of a prism has been given.
A). Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)
Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8
= 30
Area of the base = 8×5 - 2×2 = 36 cm²
Surface area of the prism = 30×5 + 2×(36)= 222 cm²
Volume of the prism = volume of the bigger prism - volume of the smaller prism cut off
= 8×5×5 - 2×2×5
= 200 - 20
= 180 cm³
B). Surface area of the prism if it's height is 10 cm,
Surface area = 30×10 + 2×(36) = 372 cm²
Volume of the prism = 8×5×10 - 2×2×10
= 400 - 40
= 360 cm³
C). Increase in surface area = 372 - 222 = 150 cm²
% increase in the surface area = [tex]\frac{150}{222}\times 100[/tex] = 67.57%
Increase in volume = 360 - 180 = 180 cm³
% increase in volume = [tex]\frac{180}{180}\times 100[/tex] = 100%
