The Baldwin family walked four over five of a mile in four over nine of an hour. What is their unit rate in miles per hour?
A.) four-ninths over four-fifths equals four over nine miles per hour
B.) four-fifths over four-ninths equals one and four-fifths miles per hour
C.) four-ninths over four-fifths equals one and four-fifths miles per hour
D.) four-fifths over four-ninths equals four over nine miles per hour
Answer:
B.
Step-by-step explanation:
4/5 go over 4/9 because you are trying to find the unit rate of miles per hour. Since 4/5 is the mile, put that over 4/9. Then, simply divide the two fractions. Which is 1 over 4/5.

You need to cut a 9 foot piece of plywood into 12 inch sections. Every cut also removes 1/8 inch. How much of the plywood will be left after cutting the 12 inch sections?
11 inches of the plywood will be left after cutting the 12 inch sections.
What is Fraction?A fraction represents a part of a whole.
Given that we need to cut a 9 foot piece of plywood into 12 inch sections and every cut also removes 1/8 inch.
We are to find the quantity of plywood that will be left after cutting the 12 inch section.
We know that 1 foot = 12 inches.
So, 9 foot = 12 × 9 = 108 inches.
Since each cut removes 1/8 inch at ever cut, so the number of 12 inch sections will be 8.
Quantity of plywood that remained after cutting the 12 inch sections will be 108-12×8-8×1/8=11
Hence, 11 inches of the plywood will be left after cutting the 12 inch sections.

Chase answers 3/4 of his math questions correctly. There were 40 questions on the test.
a. How many did he get right?
b. How many did he miss?
Chase answered 30 questions correctly and missed 10 questions.
Explanation:To find the number of questions Chase got right, multiply the fraction of questions answered correctly (3/4) by the total number of questions (40):
Number of questions answered correctly = (3/4) * 40 = 30
To find the number of questions Chase missed, subtract the number of questions he got right from the total number of questions:
Number of questions missed = 40 - 30 = 10

Misha used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below: Color of Marble Number of Times Rolled Blue 20 Green 18 Yellow 12 Heads Tails 28 22 Using Misha's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
To solve this problem, let us first remember that probability is:
Probability = number of successful events / number of total events
Now, let us first calculate the probability of getting a blue marble. There are 20 blue marbles out of 50 total marbles, therefore the probability is:
P (blue marble) = 20 / 50 = 0.4
Next, let us calculate for the probability of landing tails up. There are 22 tails success out of 50 times the coin was tossed, therefore the probability is:
P (tails) = 22 / 50 = 0.44
Finally, since we want to find the Probability of getting blue and Probability of landing tails, we multiply the two:
P (blue and tails) = 0.4 * 0.44
P (blue and tails) = 0.176 (ANSWER)
Now if the choices are in fraction:
P (blue and tails) = (20 / 50) (22 / 50) = 440 / 2500
Answer:
The answer is 440/2500

Write down three different improper fractions for the number four
Which expression could be used to determine the product of –4 and 3 1/4?
To determine the product of -4 and 3 1/4, multiply the whole numbers and the fractions separately, and then add the results together.
Explanation:The product of -4 and 3 1/4 can be determined by multiplying the whole number part, -4, by the whole number part of the mixed number, 3, and then multiplying the fraction part, 1/4, by the whole number part of the mixed number and adding the result to the previous product.
So, -4 × 3 = -12
and (-4) × (1/4) = -1
Therefore, the product of -4 and 3 1/4 is -12 - 1/4 = -12 1/4.
To find the product of -4 and 3 1/4, convert the mixed number to an improper fraction and then multiply.
Explanation:The product of -4 and 3 1/4 can be found using the expression:
-4 x 3 1/4
To multiply a whole number by a mixed number, you can convert the mixed number into an improper fraction and then multiply:
-4 x 13/4
Multiplying whole numbers and fractions can be done by multiplying the numerators and denominators separately:
-4 x 13 = -52
4 x 1 = 4
The final answer is -52/4, which simplifies to -13.
which of the following are valid names for the given triangle ? check all that apply
Answer: B. ΔMLZ
D. ΔLMZ
E. ΔZML
Step-by-step explanation:
In the given picture we have one triangle with three vertices as
Vertex L
Vertex M
Vertex Z
To name a triangle we use the labels of the vertices of the triangle, which are commonly written in capital letters.
When we name a triangle, we can start with any vertex but we need to keep the letters in order as you go around the triangle.
Therefore, the possible names of the triangle are :-

Triangle JKL is isosceles. The meansure of angle J is 72degrees and the measure angle K is 36 degrees. Which satement describes angle L?
Angle L in triangle JKL is [tex]\( 180^\circ - (72^\circ + 36^\circ) = 72^\circ \)[/tex]. Therefore, angle L measures [tex]\( 72^\circ \).[/tex]
1. Start with the fact that triangle JKL is isosceles, which means that angles J and K are congruent.
2. Given that angle J measures [tex]\( 72^\circ \)[/tex] and angle K measures \( 36^\circ \), the sum of angles J and K is [tex]\( 72^\circ + 36^\circ = 108^\circ \).[/tex]
3. Since the triangle is isosceles, the base angles (angles J and K) are congruent, so each measures half of the sum of angles J and K, which is [tex]\( \frac{108^\circ}{2} = 54^\circ \).[/tex]
4. Since angle L is the remaining angle in the triangle and the sum of the angles in a triangle is \( 180^\circ \), we subtract the sum of angles J and K from [tex]\( 180^\circ \)[/tex] to find the measure of angle L: [tex]\( 180^\circ - 108^\circ = 72^\circ \)[/tex].
5. Therefore, angle L measures [tex]\( 72^\circ \)[/tex].
