Answer:
w = 9
m <4 = 157
m<2 = 23
Step-by-step explanation:
The measure of the arc of a straight line is 180⁰.
so angle 1 + angle 3 = 180⁰.
(3w - 4) + 157 = 180
3w = 27
w = 9
Answer:
w = 9
m 4 = 157
m<2 = 23
Step-by-step explanation:
3*9 - 4 = 23
23 + 157 = 180 so it is correct.
180 - 23 = 157

Katie is 1.52 m tall. George is 6 cm shorter than Katie. How tall is George?
Give your answer in m
Answers
Answer:
1.46 cm
Step-by-step explanation:
You have to first convert meters into centimeters to make everything easier. (1m = 100cm)
1.52 meters is 152 centimeters
152-6 = 146 cm
146 cm divided by 100 is 1.46 meters
George is 1.46 meters tall

Express the ratio of 300 miles to 25 gallons of gasoline as a unit rate. Simplify your answer. Show your work
Answers
Answer:
1 gallon to 12 miles
Step-by-step explanation:
Distance = 300 miles
Gasoline used = 25 gallons
Expressing as a unit rate :
Distance covered per gallon of gasoline :
Distance / gasoline used
300 / 25
12 miles
Hence, the unit rate is :
1 gallon of gasoline = 12 miles
1 gallon of gasoline will cover 12 miles in distance.

which choice is a correct congruence statement for the triangles?
Answers
The reason why is because the order is important when it comes to congruent statements. I'm referring to the order of the letters of ACB and CAD.
Each answer choice has "ACB" in that exact order shown on the left hand side of each congruent statement. We have "A" listed first, then "C" next. In short, segment AC is the first thing mentioned of ACB. This means that we need to list out segment AC as the first thing for the other triangle as well, in order to have a match. Segment AC is the same as segment CA, which is the first segment mentioned in triangle CAD. That's why choice 3 is the answer.
Note how something like triangle CDA won't work since segment CD is listed first, which doesn't pair up with segment AC. This allows us to rule out the first answer choice. Choices 2 and 4 can be eliminated for similar reasons.
Put another way: let's assume choice 1 was the answer. That would mean that AC = CD as they are the first pair of letters of ACB and CDA respectively. But the diagram shows that AC = CD is not true; otherwise, the segments would have similar tickmarks to show they are the same length. This is an alternative way to see why choices 1, 2, and 4 can be crossed off the list.
A panda and a giraffe start moving towards each other when they are 300 feet apart. The panda is running at a speed of P feet per minute, and the giraffe is moving G feet per minute faster. How soon will they meet?
Answers
Answer:
(2P + G) feet/min
Step-by-step explanation:
Speed of the panda = P
Speed of the giraffe = P + G
Thus,
Speed of Panda + Speed of Giraffe = approaching time
= P + P + G
= 2P + G
Thus, The panda and the giraffe are approaching each other at a rate
of (2P + G) ft/min

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 20 milligrams of Medication A with 16 milligrams of Medication B. However this week, the doctor said to only use 8 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?
Answers
Answer:
10 milligrams of Medication A
Step-by-step explanation:
We'll write proportions/ratios for this:
20:16 is the usual proportion, and x:8 is this week's dose. The ratio from A to B has to be equal, so
20/16 = x/8
Cross-multiply:
(20)(8) = (16)(x)
160 = 16x
divide both sides by 16
x = 10

D)
The ordered pairs must have y = 0 for one coordinate.
PLEASE HELP!!
Answers
Answer:
Solution of a System. In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system.
Answer: A) The ordered pairs must lie near the graphed equation

Determine if the figure is a parallelogram. Justify your answer by picking the property that verifies it is a parallelogram or the one the property that it fails to meet the criteria for.
1. Is the figure a parallelogram? Yes or NO??
2. Why?? A. Both Diagonals Bisect Each Other, B. One set of Opposite Sides are parallel and congruent, C. Both sets of opposite sides are parallel, D. Both sets of opposite sides are congruent, E. Both Pairs of opposite angles are congruent.
Answers
Answer:
B and D both lead to failure. I have no idea how to pick which one is right. I guess D but don't be surprised if it is B. The question tries to do too much.
D
Step-by-step explanation:
No.
You need one more fact.
You can't pick A. Angles are not noted.
B: there is no mention of parallel sides. This is why the proposition fails to give a parallelogram.
C: you haven't got both sides being parallel. You haven't even got one set of opposite sides being parallel
D: This is probably another alternative. You don't know anything about 1 set of opposite sides.
E: No angles are marked.
