Calculate the cost for the fuel needed for Sam to drive to Nanaimo to tofino
(15 points)
Answer:
cost of Sam of fuel from Nanaimo to Tofino(207km) is $34.78
Step-by-step explanation:
Diatance from Nanaimo to Tofino is 207km.
Now:
fuel consume in 100km= 12L
fuel consume in 1km=12/100L
We have to find consumption of fuel in 207km.
fuel consume in 207km=12/100 × 207km
= 24.84L
Price of 1 liter= $1.40
Price of 24.84 liters=$1.40 × 24.84
=$34.78

What was Maria’s team score
Answer:
-2
Step-by-step explanation:
So Maria's team skipped 8 turns, losing 8 points, putting them at -8 points. But, Maria's team also guessed correctly 6 times, putting them at -8 + 6 points.
So now we can subtract 8 from 6, or you could subtract 6 from 8(If you do the latter, make sure the answer is negative.):
-8 + 6 = -2
or
6 - 8 = -2
or
8 - 6 = 2 Then make it negative: -2
The second side of a triangle is 3 times the first side. The third side of a triangle is 2 1/2 times the first side. If the perimeter of the triangle is 65 feet, find the length of each side.
Answer:
F=first side; S=second side=3F; T=third side=2.5F
.
F+S+T=60ft
F+3F+2.5F=60ft
6.5F=60ft
F=9.23ft
S=3F=3(9.23ft)=27.69ft.
T=2.5F=2.5(9.23)=23.08ft

Name 4 collinear points
Answer:
B) H, N, K, I
Step-by-step explanation:
Collinear points are points that are on the same line. Therefore, the answer is B.
The points H, N, K, and I are collinear which is the correct answer that would be an option (B).
What are the collinear points and the coplanar?Collinear points are defined as points that are along a straight line represented by a collinear. Because a straight line may be drawn continuously between any two points, they are always collinear. There can be a collinear relationship from three or more points, although it is not necessary.
A group of points that are coplanar, or a planar surface that extends endlessly in all directions, are all located on the same plane. Four or more points may or may not be coplanar, however, any two or three points are always coplanar.
We have given a line and a planar surface with points H, N, K, I, M, N, O, J, K, and L.
At the line, points H, N, K, and I are collinear.
Hence, the points H, N, K, and I are collinear which is the correct answer that would be an option (B).

if angle 1 and angle 2 form a linear pair. if m angle 1=(5x+9) and m angle 2= (3x+11), find the measure of each angle
Answer:
5x+9 = 109
3x+11 =71
Step-by-step explanation:
A linear pair adds to 180
5x+9 + 3x+11 =180
Combine like terms
8x + 20 =180
Subtract 20 from each side
8x +20-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x=20
5x+9 = 5*20+9 = 100+9 = 109
3x+11 = 3*20+11 = 60+11=71

g(x) = –2x – 9 What is g(–7)? A. 5 B. –1 C. –5 D. –23
Answer:
D. -23
Step-by-step explanation:
The question wants you to plug in the -7 into the equation. So in this case it wants you to plug the -7 in so it looks like this:
-2(-7)-9
Now it's just simplify which would be easy. Follow PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction). Do the multiplication first so you get -14-9 and then you'll get -23.

2. The area of Mr. Bodus rectangular farm is 5500 cm², its width is 11 m find the length of the farm
Answer:
5 m
Step-by-step explanation:
We convert m to cm by adding 2 zeroes. So 11m = 1100 cm
A = l*w
where l = length and w = width
so w = 11 m
we are looking for l (length)
so set up an equation,
5500 = 11 * l
and divide by 11 on both sides
5500 / 11 = l = 500 cm
Check: 11 * 500 = 5500
We can remove two zeroes to get the value in meters.
500 cm = 5 m

please i need helppp
Answer:
x=50°
Step-by-step explanation:
x+3°+x+20°+x+7°=180°
or,3x+30°=180°
or,3x=150°
or,x=50°
Answer:
50
Step-by-step explanation:
→ First add all the angles together as angles on a straight line add to 180°
x + 3 + x + 20 + x + 7 = 180
→ Simplify
3x + 30 = 180
→ Minus 30 from both sides
3x = 150
→ Divide both sides by 3
x = 50

A line with a slope of 1 passes through the point (1,6). what is its equation in slope-intercept form
If the geometric mean of a and 34 is 6 sqrt(17) find the value of a
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements, [tex](n_1, n_2, ..., n_n)[/tex], is given by:
[tex]G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}[/tex]
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
Two elements(n = 2), a and 34.[tex]G = 6\sqrt{17}[/tex]Thus:
[tex]\sqrt{34a} = 6\sqrt{17}[/tex]
We find the square of each side, so:
[tex](\sqrt{34a})^2 = (6\sqrt{17})^2[/tex]
[tex]34a = 36\times17[/tex]
Simplifying both sides by 17:
[tex]2a = 36[/tex]
[tex]a = \frac{36}{2}[/tex]
[tex]a = 18[/tex]
The value of a is 18.
