Answer:
1 1/6
Step-by-step explanation:
2+5/6=7/6 but it is an improper fraction so you turn it into a mixed fraction which is one whole number one over six
Answer:
7/6
Step-by-step explanation:
because the denominator are the same we add the numerator
How would you graph a line through the point (-2, -5), with a slope of 2/7? Be specific.
First, you would plot the point (-2,-5). The next part requires an understanding of what slope is. My teacher told me slope was "rise over run." Basically, the numerator is how much the value of y increases when x increases by the number that's in the denominator. What that means is, when you add 7 to the x value, you add 2 to the y value. You can use this to find another point to graph.
(-2+7,-5+2)
=(5,3)
You can plot this point and draw a line through both points, and you're finished.
Another thing could do is draw a slope triangle. Draw a line (segment) from (-2,-5) for 7 units in the direction of the x-axis. Draw a line (again, a segment, really. We have to be technical xD) from where that segment ends for 2 units in the direction of the y-axis. Plot a point where that ends, and it should be (5,3). Draw a line through (5,3) and (-2,5), and you're done.

recursive formula for 3,5,7,9,11
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 5 - 3 = 7 - 5 = 9 - 7 = 11 - 9 = 2
A recursive formula allows a term in the sequence be found by adding d to the previous term, then
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2 : with a₁ = 3

Step-by-step explanation:
Carla and Andrew have 29 puppies. Andrew has 8 more than twice Carla How many puppies does person have?
Answer:
Andrew has 22 puppies, Carla has 7 puppies.
Step-by-step explanation:
Let's set up an equation.
Carla and Andrew have 29 puppies.
C + A = 29
Andrew has 8 more than twice Carla.
A = 2C + 8
Let's use substitution by plugging A into C + A = 29.
A = 2C + 8 & C + A = 29
C + (2C + 8) = 29
Now, let's combine like terms.
3C + 8 = 29
Subtract 8 from both sides.
3C = 21
Divide both sides by 3.
C = 7
Carla has 7 puppies. Plug in this value back into C + A to find how many puppies Andrew has.
C + A = 29
7 + A = 29
A = 22
Andrew has 22 puppies.
Let's check our work. Plug in Andrew and Carla's number of puppies back into our original equations.
C + A = 29
7 + 22 = 29
29 = 29
Correct!
A = 2C + 8
22 = 2(7) + 8
22 = 14 + 8
22 = 22
Your answer is correct!
Hope this helps!

Work out the area of the triangle. 13m 12m and 5m
Answer:
30m²
Step-by-step explanation:
To find the area of a triangle, you need to ensure that the triangle is a right-angled triangle. We can use the Pythagoras Theorem to help us prove that.
a² + b² = c²
5² + 12² = 169
13² = 169
By converse of Pythagoras Theorem, the triangle is a right-angled triangle.
Thus, you can directly find the area of the triangle using the formula: base × height ÷ 2.
Area = 12 × 5 ÷ 2
= 30m²
At a sports event, 1, 045 spectators will be
transported to a stadium in buses. Each bus
holds up to 85 spectators. Which inequality best describes n, the number of buses that are needed to transport spectators?
Answer:
85n >/= 1,045
Step-by-step explanation:
85 people times n buses has to equal or exceed 1,045 people
85n is greater than or equal to 1,045
85n >/= 1, 045
n >/= 12.29
So, since n has to be greater than or equal to 12.29, and there is no 29/100ths of a bus, they would need 13 buses (in case there's a follow-up question)
Please lmk if you have questions.
Answer:
n = 13
Step-by-step explanation:
Divide 1045 spectators by 85:
1045
---------- = 12.29
85
Obviously it won't suffice to use 12 busses; this 12.29 must be rounded up to 13 busses. n = 13

Answer:
32π + 96 [tex]cm^{2}[/tex] = exact area
196.48 [tex]cm^{2}[/tex] = area to the nearest 100th
Step-by-step explanation:
Area of semicircle = 1/2π[tex]r^{2}[/tex] = 1/2π[tex]8^{2}[/tex] = 1/2π(64) = 32π
Area of triangle = 1/2bh = 1/2(16)(12) = 96
Total area = 32π + 96 [tex]cm^{2}[/tex]
or 100.48 + 96 = 196.48 [tex]cm^{2}[/tex]
32π + 96 cm² = exact area
196.48 cm² = area to the nearest 100th
What is a semi-circle?A semicircle is a one-dimensional locus of points that makes up one half of a circle in mathematics. A semicircle's whole arc is always 180 degrees long. It just has one symmetry line.
Given
Area of semicircle = 1/2πr² = 1/2π(8)² = 1/2π(64) = 32π
Area of triangle = 1/2bh = 1/2(16)(12) = 96
Total area = 32π + 96 cm²
or 100.48 + 96 = 196.48 cm²

Answer: d is 53 degrees, c is 5, g is 13, e is 90 degrees, f is 37 degrees, b is 12 .
Step-by-step explanation:
Since they're congruent you just compare the two and replace them. You have the answers on both sides, they're just split up. So look at one side, then the other, and see what you can find. Repeat.
Answer and Step-by-step explanation:
Since the triangles are congruent, that means all the variables correspond to the values of the other triangle, and vise versa.
g = 13
b = 12
f = 37
a = 90
c = 5
d = 53

to relate a ball's surface area S (in square Inches) to its radius r (in inches). Suppose a ball has a surface area of 226.8
square Inches. What is its radius?
Round your answer to the nearest tenth
Answer:
r = 4.24 inches
Step-by-step explanation:
Given that,
The surface area of the ball, A = 226.8 sq inches
The formula for the surface area of a sphere is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the ball
[tex]r=\sqrt{\dfrac{A}{4\pi}} \\\\r=\sqrt{\dfrac{226.8}{4\pi}} \\\\r=4.24\ inch[/tex]
So, the radius of the ball is 4.24 inches.

Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 6.4 cm. Round your answer to the nearest tenth of a cubic centimeter
Answer:
6.3 cm^3
Step-by-step explanation:
volume of a pyramid = 1/3(length x width x height)
perimeter of a square = 4 x length
6.9 = 4 x length
length = 6.9 /4 = 1.725
Volume = 1/3 x (1.725 x 1.725 x 6.4) = 6.348

Answer:
175.2 square feet
Step-by-step explanation:
The lateral area is the total area of the side faces. It excludes the area of the top and bottom "bases" of the prism.
It can be found by adding the areas of the four rectangles. The two you can't see have the same areas as the two you can see.
Since the height of each rectangle is 4 feet. the total area will be the product of that and the perimeter of the prism.
LA = Ph . . . . perimeter times height
LA = 2(L+W)h . . . . the perimeter is twice the sum of length and width
LA = 2(12.3 ft + 9.6 ft)(4 ft) = 2(21.9 ft)(4 ft) = 175.2 ft²
The lateral area of the prism is 175.2 ft².
__
The attachment shows scribbling on two of the faces that contribute to the lateral area. As stated above, the other two faces are the same size as these.
