Answers
Answer:
-4
Step-by-step explanation:
1st Step:
Set up our equation, so we get x + 69 + 25 + 90 = 180
Remember: All sides of a triangle add to 180.
2nd Step:
Now that we've got our equation: x + 184 = 180. Subtracting 184 from 180 gives us -4, which is our answer.
Key Points To Remember:
- The angles of a triangle always add up to 180.
- The little square at the bottom of the triangle means the angle is 90.

Jimmie selects a marble from a bag, notes the color, and returns the marble to the bag. After 40 trials, he selects 12 orange marbles, 18 green marbles, and 10 blue marbles. Which of the following experimental probabilities are correct based on the results?
Answers
Answer:
C) P(not orange) = 7/10; P(not green) = 11/20; P(not blue) = 3/4
Step-by-step explanation:
The sum of the probabilities of all outcomes must equal 1.
Total trials = 40
If he selects 12 orange marbles out of 40 trials, then
P(orange) = 12/40 = 3/10
⇒ P(not orange) = 1 - 3/10 = 7/10
If he selects 18 green marbles out of 40 trials, then
P(green) = 18/40 = 9/20
⇒ P(not green) = 1 - 9/20 = 11/20
If he selects 10 blue marbles out of 40 trials, then
P(blue) = 10/40 = 1/4
⇒ P(not blue) = 1 - 1/4 = 3/4

Find the lateral surface area of the triangular prism. A) 84 in2 B) 90 in2 C) 96 in2 D) 104 in2.
Answers
The lateral surface area of the provided triangular prism is 96 square inches. Option C is the correct option.
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The lateral surface area of the triangular prism can be calculated with the following formula.
[tex]A_{LS}=h(a+b+c)[/tex]
Here, (a,b,c) are the bases of the rectangular faces and (h) is the common height.
The image of the triangular prism is attached below. In the given triangular prism, the common height is 8 in and bases of the rectangular faces are 5 in, 4 in and 3 in long.
To find the lateral surface area of the given triangular prism, put the values in the above formula.
[tex]A_{LS}=8(5+4+3)\\A_{LS}=8(12)\\A_{LS}=96\rm\; in^2[/tex]
Thus, the lateral surface area of the provided triangular prism is 96 square inches. Option C is the correct option.

Answers
there are 55 red marbles in the jar
Answer:
There are 55 red marbles in the jar.
Step-by-step explanation:
Green marbles = 125 x 2/100 = 2.5
Blue marbles = 125 x 54/100 = 67.5
Red marbles = 125 - 67.5 - 2.5 = 55

Answers
Answer:
< x = 120°
Step-by-step explanation
Step 1:
According to angle sum property,
y + 50 + 70 = 180
Step 2:
x and y are linear pairs, forming a supplementary angle.
Therefore,
x + y = 180
Step 3:
Since they are both equal to 180, equate the values
y + 50 + 70 = x + y
x = 70 + 50
x = 120

Alex’s SUV gets an average of only 15 miles per gallon. Gas costs $2.19 per gallon. Write a rule that gives the cost of a trip C when you know the number of miles d that Alex travels.
Answers
Answer:
(d miles)/(15 miles/gallon)*($2.19/gallon)
Step-by-step explanation:
Fuel efficiency = 15 miles/gallon.
Gas is $2.19/gallon.
Total cost is y.
miles is d
The equation that provides the total fuel for a trip in Alex's SUV would be:
Fuel for d miles (gallons) = (d miles)/(15 miles/gallon)
This is the total fuel required for a trip of d miles. Multiply this times the cost per gallon to find the total ciost of the trip:
(d miles)/(15 miles/gallon)*($2.19/gallon) = Total cost for a trip of d miles.

Answer:
See step-by-step, as it depends which value of pi you use.
Step-by-step explanation:
Equations
Diameter = [tex]2r[/tex]Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)Assuming the pond is circular...
Diameter of pond = 50 yd ⇒ r = 50 ÷ 2 = 25 yd
Substitute r = 25 into the equation for the area of a circle:
[tex]\implies A= \pi \times25^2=625\pi[/tex] yd²
Using [tex]\pi =3.14[/tex], area = 1962.5 yd²
Using [tex]\pi=\dfrac{22}{7}[/tex], area = 1964.3 yd² (nearest tenth)
Using [tex]\pi[/tex], area = 1963.5 yd² (nearest tenth)
