Which ordered pair (p,r) is the solution to the given system of linear equations?
Answer:
(p,r) = (1/3, 2/9)
Step-by-step explanation:
Here, we want to solve a system of equations
We can rewrite the second equation by dividing through by 2
So we have;
4p + 3r = 2
and
5p - 3r = 1
Add both equations:
9p = 3
p = 3/9
p = 1/3
Recall ;
5p - 3r = 1
3r = 5p - 1
Substitute the value or p here
3r = 5(1/3)-1
3r = 5/3 - 1
3r = 2/3
r = 2/9
So we have the solution set as;
(p,r) = (1/3 , 2/9)

In triangle HIJ, N is the centroid. If HK = 10, find KI.
Given:
In triangle HIJ, N is the centroid and [tex]HK=10[/tex].
To find:
The value of KI.
Solution:
In a triangle, the centroid of the triangle is the intersection of its medians.
Median of a triangle from a vertex divides the opposite side into two equal parts.
It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.
Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.
[tex]KI=HK[/tex]
[tex]KI=10[/tex]
Therefore, the value of KI is 10 units.

What are the solutions to the quadratic equation below?
4x^2 + 28x + 49 = 5
Answer:
C
Step-by-step explanation:
Answer:
C.
[tex]x=\frac{-7±\sqrt{5 } }{2}[/tex]
Step-by-step explanation:
4x² + 28x + 49 = 5
4x² + 28x + 49 - 5 = 0
4x² + 28x + 44 = 0
4(x² + 7x + 11) = 0
4(x² + 7x + 11) ÷ 4 = 0 ÷ 4
x² + 7x + 11 = 0
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
a = 1
b = 7
c = 11
[tex]x=\frac{-7±\sqrt{7^{2}-4((1)(11)) } }{2(1)}[/tex]
[tex]x=\frac{-7±\sqrt{49-4((1)(11)) } }{2(1)}[/tex]
[tex]x=\frac{-7±\sqrt{49-44 } }{2(1)}[/tex]

A chair rental company charges $100 for delivery plus $3 per chair.
Write an explicit function for the total cost, T(c), of renting c number of
chairs.
Answer:
T(c) = 100 + 3*c
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
T(c) = 100 + 3*c
Answer:
T ( c)= $ 100 + $ 3 c
Step-by-step explanation:
Given that :-
Fee for delivery = $ 100Cost per chair = $ 3No. of chair = cTo Find :-
Total cost T( c) of renting c no. of chairs.Solution :-
Total Cost, T ( c) = Fee + cost per chair × no. of chairs.
T ( c) = $ 100 + $ 3 × c
T ( c) = $ 100 + $ 3 c

D. 82
Answer:
76
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(sum of Intercepted Arcs)
94 = 1/2(x+112)
Multiply each side by 2
2*94 = x+112
188 = x+112
Subtract 112
188-112 =x

Lamar made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $43.80If the beads cost $3.80 for each necklace, how much did each pendant cost?
Answer:
3.50
Step-by-step explanation:
Necklace has beads and a pendant
b +p
There are 6 necklaces at a cost pf 43.80
6(b+p) =43.80
The beads for one necklace cost 3.80 so replace b with 3.80
6(3.80+p) =43.80
Divide each side by 6
6(3.80+p)/6 =43.80/6
3.80 +p = 7.30
Subtract 3.80 from each side
3.80+p-3.80 = 7.30 -3.80
p =3.50

Which of the following expressions are equivalent?
1. 5(a + 3)
2. 5a + 15
3. 3(2a + 5)
Answer:
1 and 2 are equivalent
For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.
Johanna buys two poster frames that have the same area, but different shapes. One is a rectangular frame with a width of 40 inches and a length of 30 inches. The other frame is square. What a poster with dimensions of 36 inches X 36 inches fit in the square frame?
Answer:
No, the poster would not fit in the frame
Step-by-step explanation:
A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.
A square is a quadrilateral in which all sides are equal.
Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:
Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²
Since the square frame has the same area as the rectangular frame, hence:
Area of square frame = length * length
length² = 1200
length = √1200 = 34.64
Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.
Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.
How many positive whole numbers less than or equal to 360 are divisible by 2 or 3, but are not divisible by 18?
Answer:
You can do this through trial and error.
The answer is 260.
Step-by-step explanation:
Off the bat, we know all even numbers are multiples of 2 so 180 numbers to be precise. Now we find how many even Numbers are divisible by 18 so all factors of 18 should be satisfactory so 18, 36 etc. there are 20 of those so 180 - 20 = 160
now multiples of 3. 360 dived by 3 is 120 - 20 =100, 100+160 = 260
Find the volume of the sphere. Round your answer to the nearest tenth.
Use 3.14 for a.
A sphere has a diameter of 4.4 centimeters.
The volume of the sphere is about
cm^3 just
Answer:
Volume of sphere = 44.57 cm³
Step-by-step explanation:
Given:
Diameter of sphere = 4.4 centimeter
Value of π = 3.14
Find:
Volume of sphere
Computation:
Radius of sphere = Diameter of sphere / 2
Radius of sphere = 4.4 / 2
Radius of sphere = 2.2 centimeter
Volume of sphere = [4/3][π][r³]
Volume of sphere = [4/3][3.14][2.2³]
Volume of sphere = [4/3][3.14][10.648]
Volume of sphere = [1.333][3.14][10.648]
Volume of sphere = 44.568
Volume of sphere = 44.57 cm³
