Answer:
4th answer aka the last one
Step-by-step explanation:
A quadrilateral always has interior angles that add up to 360 degrees.
Answer:
We set up our equations:
35x+40y = 1850 eq1
x+y = 50 eq2
Substituting eq 2 into eq 1,
35x+40(50-x) = 1850
35x+2000-40x = 1850
-5x+2000 = 1850
-5x = -150
x = 30
Substitute value of x into eq 2.
x+y = 50
30+y = 50
y = 20
Car 1 consumes 30 gallons of gas.
Car 2 consumes 20 gallons of gas.

The question is not complete. It should read;
<span>Lisa and Bart spin this spinner 60 times the result are below/ black=17 blue=15 orange=21 purple=7 a. What is the experimental probability of a spin of orange? B which color had an experimental probability that matched its theoretical probability
<u>Answers</u>
a) 0.35
b)Blue
<u>Explanation</u>
The probability of an event is its chance to occur.
Probability is found by the formula,
Probability = (Number of favourable outcome)/(Number of total outcome)
Part a
</span>The orange are 21 and the total spins are 60.
Probability (orange) = 21/60
= 0.35
Part 2
The theoretical probability of blue is normally 25%.
By calculating the experimental probability of blue we get,
P(blue) = 15/60
= 1/4
In percentage
1/4×100 = 25%
So, the <span>color that had an experimental probability that matched its theoretical probability is blue.</span>
