Answer:
69.39 kilometers
Step-by-step explanation:
total kilometres driven on each trip = total kilometres driven on all trips / total number of visits
6,870.1 / 99 = 69.394949
To the nearest hundredth means we are rounding off the third number after the decimal point. The second number after the decimal is the hundredth. The third number is less than 4, so zero would be added to the preceding number
69.39 kilometers

Two glasses of milk and 3 snack bars have a total of 62 carbohydrates, and 3 glasses of milk and 2 snack bars have a total of 58 carbs. Determine how many carbs are in one glass of milk in one snack bar.
Step-by-step explanation:
So looking at this question, we have two variables (1 - a glass of milk; 2 - a snack bar) and two equations to use to solve for the two variables. Remember that for any number of variables, you need that same number or more equations to solve for the variables.
Let's say that a glass of milk is represented by g and a snack bar is represented by s.
So we essentially have two equations here:
4 glasses of milk + 3 snack bars = 88 carbs, or:
4g + 3s = 88
2 glasses of milk + 4 snack bars = 74 carbs, or:
2g + 4s = 74
Now that we have this, we can solve for our equations. There are two ways to do this:
SUBSTITUTION - solve for one variable, then substitute it in
Let's solve for g using the second equation. First, we'll isolate g by subtracting 4s from both sides.
2g = 74 - 4s
Next, we can divide the whole equation by 2 to solve for g.
g = 37 - 2s
Now, we can substitute this into the first equation for g and solve for s.
4g + 3s = 88
4(37 - 2s) + 3s = 88
148 - 8s + 3s = 88
148 - 5s = 88 (now subtract 88 from both sides and add 5s to both sides)
60 = 5s
s = 12
Now we can use this to solve for g in the original equation
g = 37 - 2s
g = 37 - 2(12) = 37 - 24 = 13
ELIMINATION - eliminate one variable to solve for the other, then use that to solve for the first
Let's look at our two equations
4g + 3s = 88
2g + 4s = 74
Let's eliminate the variable g first by multiplying the second question by -2.
4g + 3s = 88
-4g - 8s = -148
If we add these two equations together, we get
-5s = -60
Divide both sides by -5 and we get
s = 12
Now, we can plug s into either equation to solve for g as we did above.

Given a set of attributes, can you make one triangle, no triangles, or many triangles?
jo says, "the attributes of my triangle are sides that are 3cm and 9cm long. I can make only one triangle because I have to connect the ends of my two sides."
do you agree or disagree? why?
Answer:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

question: write the function as an equation, the function is linear btw
Answer:
y - 8 = 4(x - 2)
Step-by-step explanation:
Note that as we increase any x value by 1, the corresponding y value increases by 4. Thus, the slope is 4.
Using the slope-intercept formula, we get:
y - 8 = 4(x - 2)
Check: If x = 5, does this formula result in y = 20?
y = 8 + 4(x - 2) with x = 5 comes out to y = 8 + 4(3) = 8 + 12 = 20. YES
Solve: -8 = -7 + x X =

A bicycle ramp used for competitions is a
triangular prism. The volume of the ramp
is 313.2 cubic feet. Write and solve an
equation to find the width of the ramp.
Possible student work:
V=Bh
13.4ft
Answer:
8.7 feets
Step-by-step explanation:
As obtained frommthe diagram attached :
Base, b of triangle = 6 feets
Height of triangle, h = 12 feets
Volume of a Triangular Prism is obtained using the relation :
Base Area * Width
Base area of prism :
0.5 * base * height
0.5 * 6 * 12 = 36ft²
Width, w of the ramp =x
Volume, V = 313.2 ft³
V = base area * width
313.2 = 36 * x
313.2 = 36x
x = 313.2 / 36
x = 8.7 feets

Como calcula-se a àrea de um cubo
Answer:
Spanish:
En palabras, el área de la superficie de un cubo es el área de los seis cuadrados que lo cubren. El área de uno de ellos es un * a, o un 2. Como todos son iguales, puedes multiplicar uno de ellos por seis, por lo que el área de la superficie de un cubo es 6 veces uno de los lados al cuadrado.
Además, un cubo tiene 6 caras. El área de cada cara se encuentra elevando al cuadrado la longitud del lado. Multiplica el área de una cara por el número de caras para obtener la superficie total del cubo.
Step-by-step explanation:
English:
In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
Also, A cube has 6 faces. The area of each face is found by squaring the length of the side. Multiply the area of one face by the number of faces to get the total surface area of the cube.

What is percentage?Percentage is a number or ratio expressed as a fraction of 100.
Here given that Juan's puppy currently weighs 80 pounds and his is a 60% increase in weight from when he got her.
Let's suppose original weight of puppy was x pounds
We can calculate x as
[tex]x+ \frac{60}{100} \times x=80\\\\x+ \frac{6}{10} \times x=80\\\\x+ 0.6\times x=80\\\\\\1.6x=80\\\\x=\frac{80}{1.6} \\\\x=\frac{800}{16} \\\\\\x=50[/tex]

Answer:
Complementary
x = 55
Step-by-step explanation:
Complementary angles add up to 90°, while supplementary angles add up to 180°.
In this situation, the two angles add up to 90° (the little box means that an angle is a 90° angle) So, the angles are complementary.
Now, we can write this equation.
x + x - 20 = 90
Simplify.
2x - 20 = 90
2x = 110
x = 55
Just in case, let's check the answer.
Substitute x = 55 into (x + x - 20 = 90)
55 + 55 - 20 = 90
110 - 20 = 90
90 = 90
This is true, so x = 55 is correct.

Josh is selling crafts at an outdoor market. He charges $2.25 for each door hanger he has made and $3.75 for each necklace. He knows he has sold at least 20 items at the market, but he has no more than $60 in sales.
Answer:
He sold 10 hangers and 10 neclesses
Step-by-step explanation:
Given data
Let the number of door hanger be x
and the number of neckless be y
so
x+y= 20---------1
also,
2.25x+3.75y= 60---------2
Solve 1 and 2 together
From 1
x= 20-y
put this in place of x in 2
2.25(20-y)+3.75y= 60
45-2.25y+3.75y= 60
1.5y= 60-45
1.5y= 15
y= 15/1.5
y= 10
Put y= 10 in 1
x+10= 20
x= 20-10
x= 10
Solve for x
4x = 51
1. x = 204
2. x = 47
3. x = 12.75
Answer:
C) 12.75
Step-by-step explanation:
4x=51
x=51/4
