A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km? (5 points) [1 mile = 1.6 km]
Answer:
To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.
Step-by-step explanation:
Proportions
The hybrid car can travel 40 miles per gallon.
Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.
Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.
To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.

Solve the following system of equations using substitution.
y = 2x-2
-4x-y = 26
Answer:
x = -4
y= -10
Step-by-step explanation:
Solving for x
-4x-y = 26
-4x-(2x-2) = 26
-6x+2 = 26
-6x = 24
x = -4
Solving for y
y = 2x-2
y = 2(-4) -2
y= -8-2
y = -10

What is the sum of the measures of the interior angles of a 27-gon?
Answer:
To figure out the total measure of the angles for a 27-gon, there is a formula.
n - 2 x 180* (n is the number of sides, which would be 27)
27 - 2 = 25
25 x 180* = 4500*
The total measure of the angles of a 27-gon is: 4500*

The product of two numbers has a 5 in the ones digit. Are the two numbers even or odd
The ones digit of the product of two numbers has an odd 5 in it.
What are products?
The outcome of one or more multiplications is referred to as a "product." For instance, the mathematical statement "times equals" would be written with the multiplier, the multiplicand, and their product as the variables.According to our question,
You might perform a simple calculation like 5x5 to get the odd value of 25, as 5 is odd.hence,The ones digit of the product of two numbers has an odd 5 in it.

Find the slope by using 2 sets of x,y values from the table.
Slope is change in y over change in x:
Slope = (-6 - -9) / (1 - -2) = 3/3 = 1
Then the y intercept is the value of y when x is 0. Looking at the table when x is 0 y is -7
The equation would be y = x-7

Step-by-step explanation:
Half a pepperoni pizza plus three fourths of a ham-and-pineapple pizza contains 765 Calories. One fourth of a pepperoni pizza plus a whole ham-and-pineapple pizza contains 745 Calories. How many Calories are in a whole pepperoni pizza? How many Calories are in a whole ham-and-pineapple pizza?
Answer:
Let x be the number of calories in the pepperoni pizza and y be the number of calories in ham-and-pineapple pizza. Then, we can make two equations out of the problem statement.
Eq 1: (1/2)x + (3/4)y = 765
Eq 2: (1/4)x + y = 745
By transposing, Eq 2 becomes: y = 745 - (1/4)x. We substitute this to Eq. 1:
(1/2)x + (3/4)(745 - (1/4)x) = 765
x = 660
Then we substitute x to Eq 2 to get y:
y = 580
Thus, there is 660 calories in pepperoni pizza and 580 calories in ham-and-pineapple pizza.
1. For a soccer party, Juan collects $90 for pizza. He must buy more than 5 pizzas to
feed the team. Pizzas are $7.25 for a small pizza and $10.50 for a large pizza. Let:
S = number of small pizzas he can buy & L = number of large pizzas he can buy.
Select the system of inequalities that represents this situation.
Answer:
7.25S + 10.50L ≤ 90
The system of inequalities that represents a given situation are S+L>5 and 7.25S+10.50L≤90.
Given that, For a soccer party, Juan collects $90 for pizza. He must buy more than 5 pizzas to feed the team. Pizzas are $7.25 for a small pizza and $10.50 for a large pizza.
What are inequalities?Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Let S = the number of small pizzas he can buy and L = the number of large pizzas he can buy.
Juan must buy more than 5 pizzas to feed the team.
That is, S+L>5
Pizzas are $7.25 for a small pizza and $10.50 for a large pizza=7.25S+10.50L
Juan collects $90 for pizza. So, 7.25S+10.50L≤90
Therefore, the system of inequalities that represents a given situation are S+L>5 and 7.25S+10.50L≤90.
