Answer:
1/4 chance
Step-by-step explanation:
First you need to find the probability of Tess choosing a red ribbon.
1/2
Then you need to multiply that probability by the reciprocal of 2, which is 1/2
1/2 x 1/2 = 1/4

A car uses 8 litres of gasoline to travel 160 km. How much gasoline will the car use to travel 400 km?
Answer:
20 liters of gasoline
Step-by-step explanation:
Create a proportion where x is the amount of gasoline needed to travel 400 km:
[tex]\frac{8}{160}[/tex] = [tex]\frac{x}{400}[/tex]
Cross multiply and solve for x:
160x = 3200
x = 20
So, the car will use 20 liters of gasoline to travel 400 km.
Answer:
The car will use 20 liters of gas
Step-by-step explanation:
160KM/8L = 20KM per liter
400/20 = 20
In triangle ABC, m ZA = 47°, m ZB = 62°. m ZC =
a. 81°
b. 61°
C. 71
d. 51°
Answer:
m ZC = 71 degrees. Option C.
Step-by-step explanation:
Triangles always measure a total of 180 degrees.
47 + 62 + c = 180
109 + c = 180
c = 71
Answer:
71°
Step-by-step explanation:
The total angles in a triangle should equal 180°
a + b + c = 180
47 + 62 + c = 180
109 + c = 180
180 - 109 = 71
c = 71°

Answer:
15
Step-by-step explanation:
you can add the absolute value of -7 with 8 so it's 15
The length of AD on the number line is,
⇒ AD = 15
What is mean by Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
We have to given that;
Number line is shown in figure.
And, The point A is at - 7 on number line.
The point D is at 8 on number line.
Hence, We get;
The length of AD on the number line is,
⇒ AD = | - 7 - 8 |
⇒ AD = | - 15 |
⇒ AD = 15
Therefore, The length of AD on the number line is,
⇒ AD = 15 units

Help me outtttttttttt
Answer:
∠1 = 5 degrees
∠2 = 85 degrees
Step-by-step explanation:
if we add ∠1 and ∠2 that will be 90 degrees (as it is straight angle and its already given in the picture)
( x - 12) + 5x = 90
6x -12 = 90
6x = 90 + 12
6x = 102
x = 102/6
x = 17
Put 17 in both the angles instead of x
∠1 = ( x-12)
= ( 17 - 12)
= 5
∠2 = 5x
= 5 (17)
= 85
now you can even Cross-check
5 + 85
= 90 degrees

-5/9 is rational, and its none of the other choices (integer, whole, irrational). So this value goes in the "rational" rectangle, and outside any other region.
The number [tex]-\sqrt{100}[/tex] turns into -10 after simplification. We see that this number is both rational and an integer. The best place for it is inside the "integer" circle. Note how this circle is entirely in the "rational" rectangle. We do not place it in the "whole number" circle because whole numbers are not negative.
The number [tex]\pi[/tex] is irrational since its decimal expansion goes on forever without any known pattern.
The number [tex]\sqrt{25}[/tex] simplifies to 5. This goes in the "whole number" circle.

An airplane is coming in for a landing and the pilot knows she is 5473 m above the ground and she also knows that Angle of depression from the plane to the landing strip is 58º. How far is the plane from the landing strip?
Answer:
3420 m
Step-by-step explanation:
when we say distance, we mean ground distance, right ? not air distance.
so, essentially, the angle from the straight line the plane could be going at that moment down to the touch down point on the landing strip is 58 degrees.
that means the angle of elevation (between the line to the touch down point and the height "line" of the airplane) is 90-58 = 32 degrees
the height of the airplane (= distance from ground) is 5473 m.
now, we also know that the angle between height and the ground connection to the touch down point is 90 degrees (as height is always meshed straight up/down).
so, we know even the third angle (at the touch down point between ground and the line to the airplane)
= 180 - 90 - 32 = 58 degrees.
if we imagine now a circle being drawn with the touch down point being center and going through the right- angle corner point on the ground right under the airplane, we see that the ground distance from that corner to the landing strip is the radius of that circle.
therefore, the height is tan() × r of the angle at the touch down point.
5473 = tan(58) × r
r = 5473 / tan(58) = 3420 m

Step-by-step explanation:
17. Negative numbers are closed under addition.
True or false
===========================================================
Explanation:
Picking any two negative numbers, then adding them, will result in some other negative number. This is why the set of negative numbers is closed under addition.
Examples:
-2 + (-3) = -5
-10 + (-14) = -24
-7 + (-9) = -16
This is because when you add two negatives, you're adding their positive counterparts. Going to the first example above, we would say 2+3 = 5 and then just make everything negative. There's no way to add two negative numbers, and get a positive result (and we can't get 0 either).
You can think of it in terms of money and debt. The -2 represents being 2 dollars in debt. Then adding on 3 more dollars of debt leads ultimately to 5 dollars overall in debt.
Grace and her dad are planning to attend the state fair. An adult ticket is $15.00. The price of an adult ticket is one half the price of a student ticket plus $8.00. Write an equation to determine how much Grace will pay for a student ticket.
one halfx + 8 = 15
one halfx − 8 = 15
one halfx + 15 = 8
one halfx − 15 = 8
Answer:
Option 1 is the correct equation.
Step-by-step explanation:
x = price of the student ticket.
One half price of x + $8 = adult ticket price ($15)
Answer:
The correct answer is A
Because taking the student ticket to be x
one half of x + 8 =15
