Find the distance between points M(6, -16) and Z (-1, 14) to the nearest tenth.
Distance = √((x2-x1)^2 + (y2-y1)^2)
Distance = √((-1 - 6)^2 + (14 - -16)^2)
Distance = √( -7^2 + 30^2)
Distance = √(49 + 900)
Distance = √949
Distance = 30.8

A motorboat traveling with the current went 80 miles in 4 hours. Against the current, it took 5 hours to travel the same distance. Find the rate of the motorboat in calm water.
Let x be the speed of the motorboat and y be the speed of the current.
Then, for downstream, the speed is x + y.
Now, speed = distance/time.
Distance = 80 miles.
Time for downstream = 4 hours.
So, x + y = 80/4 = 20 (1)
Against the current, that is for upstream, the speed is x - y.
Time for upstream = 5 hours.
x - y = 80/5 = 16 (2)
Adding (1) and (2), we get,
2x = 36
x = 18
Hence, rate of the motorboat in calm water = 18 miles/hour.
give that angle CFE is congruent to CFA, the measure of angle AFB = 23° and the measure of angle EFD = 69°, find the measure of angle EFB.
Answer:
m∠EFB = 157°
Step-by-step explanation:
We are given that m∠CFE = 90°
m∠AFB = 23° so;
m∠BFC = 90° - 23° = 67°
m∠EFB = m∠CFE + m∠BFC = 90° + 67° = 157°
Answer:
D. 157°
Step-by-step explanation:
Angle CFE is a right angle, as can be seen in the figure. So, m∠CFE = 90°. Two angles are congruent when they are equal. This means that angle CFE is equal to CFA, i. e., m∠CFA = 90°. Figure shown that m∠AFB + m∠BFC = m∠CFA. If m∠AFB = 23°, then, m∠BFC = 67°. It's also shown in the figure that m∠EFB = m∠CFE + m∠BFC. So, m∠EFB = 90° + 67° = 157°
If a^2-b^2=648 and (a-b)=24, what is the value of (a+b)
F.21
G.24
H.25
J.26
K.27
K.27. This is because if you were to factor a^2-b^2, you get (a+b)(a-b)=648. If you substitute a-b for 24, it would lead the equation to be 24(a+b)=648. Divide 24 from both sides to get the answer.
To find the value of (a+b), substitute a-b into the equation [tex]a^{2} - b^{2} = 648[/tex] and solve for (a+b). The value of (a+b) is 27, i.e., option K.
Explanation:To find the value of a+b, we can use the formula for the difference of squares: [tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]. Given that a-b = 24, we can substitute this value into the equation. So, we have:
648 = (a+b)(24)
Now, divide both sides of the equation by 24 to isolate (a+b):
(a+b) = 648/24 = 27. Therefore, the value of (a+b) is 27.

Haji rows his canoe 10 mph in still water. He noticed one day that he could row 4 miles upstream in the same amount of time he could row 6 miles downstream. What was the approximate speed of the current that day?
2.0 mph
3.3 mph
5.0 mph
10.0 mph
Answer : 2.0 mph
Haji rows his canoe 10 mph in still water
Speed of still water = 10 mph
Let the speed of the current = x
Upstream speed = 10 - x
Downstream speed = 10+x
Upstream Distance = 4 miles
Downstream Distance = 6 miles
[tex]Time = \frac{Distance}{speed}[/tex]
Time taken on upstream = [tex]\frac{4}{10-x}[/tex]
Time taken on downstream = [tex]\frac{6}{10+x}[/tex]
Same time taken for both upstream and downstream
So [tex]\frac{4}{10-x} = \frac{6}{10+x}[/tex]
Cross multiply it
4(10+x) = 6(10-x)
40 + 4x = 60 -6x
Add 6x and subtract 40 on both sides
10x = 20 (divide by 10)
x= 2
So speed of the current = 2.0 mph
The approximate speed of the current that day is 2.0 mph.\
The correct option is A.
Given
The speeds of the current = x
Upstream speed = 10 - x
Downstream speed = 10+x
Upstream Distance = 4 miles
Downstream Distance = 6 miles
What is speed?Speed is defined as the fraction of the total distance and time taken to complete it.
The following formula is used to calculate speed;
[tex]\rm Speed =\dfrac{Distance}{Time}[/tex]
Therefore,
The approximate speed of the current that day is;
[tex]\rm = \dfrac{Upstream \ distaance}{Upstream \ speed}= \dfrac{downstream \ distaance}{downstream \ speed}\\\\ \dfrac{4}{10-x}=\dfrac{6}{10+x}\\\\4(10+x)=6(10-x)\\\\40+4x=60-6x\\\\4x+6x=60-40\\\\10x=20\\\\x= \dfrac{20}{10}\\\\x=2[/tex]
Hence, the approximate speed of the current that day is 2.0 mph.

Enter the number that belongs in the green box.
The number that belongs in the green box is 2.
Explanation:Based on the information provided, which relates to probability and the use of a calculator, we can assume the question pertains to Mathematics, likely within a Middle School curriculum where basic probability and calculator skills are taught.
When dealing with shuffled cards or marbles in a bag, one typically calculates probabilities or expected outcomes
There are a total of eight cards: five green cards and three yellow cards.
Since the cards are well shuffled, the probability of drawing a green card is 5/8.
The probability of drawing a yellow card, in this case, would be 3/8.
Since the green cards are marked with the numbers 1, 2, 3, and 4, the number that belongs in the green box would be 2.
Final answer:
To find the number in the green box, calculate the ratio of green cards to total cards.
Explanation:
The number that belongs in the green box can be found by calculating the ratio of green cards to total cards. In this case, there are 5 green cards out of 8 total cards. To find the number that belongs in the green box, we can use the formula:
Number in green box = green cards / total cards
Number in green box = 5 / 8
Using a calculator or simplifying the fraction, we find that the number in the green box is 5/8 or approximately 0.625.

Hey can anyone help me? I just need help with the bottom table.
The question asks how many hours each person worked, and how much they earned, or basically they're asking for the right two columns to be filled in. (Total hours = how many hours each person worked, and Total pay = how much they earned)
Now let's recall the information which is given.If we look at the table, we can see we're given information for each person, Sue, Bob, and Chris. We're given their rate per hour, and the numbers of hour they worked for each day.
Now that we've looked at that, we can connect the information we're given and what the question is asking.The two things we are looking to calculate can correspond with a part of information we're given:
Total Hours <-> hours worked each day: we can see these connect as the total hours work (I'm assuming) are weekly, and to calculate the total hours worked we can look the hours worked for each day as days make up weeks. Therefore, if you just add the number of hours worked on Monday, Tuesday, Wednesday, Thursday, and Friday together, you get the total hours worked in the week.Total Pay <-> rate per hour and total hours: the total amount of pay can be calculated once we know the rate per hour and the total hours. The rate per hour is based off of the hours, it's how much is earned every hour, and the total hours include the total amount of hours worked. Therefore, if you multiply the two together you'll get the total pay. (Multiplying is essentially adding a number, another number of times, in this case it's adding the pay rate, the total hours amount of times.)Now that we know how they're connected, and therefore how to solve the equation, we can complete the calculations.Find the total hours worked for each person:
Sue: Monday: 3.5 hours, Tuesday: 10.5 hours, Wednesday: 5.25 hours, Thursday: 6 hours, Friday: 12 hours. 3.5 + 10.5 + 5.25 + 6 + 12 = 37.25 total hours workedBob: Monday: 5 hours, Tuesday: 3.5 hours, Wednesday: 7.75 hours, Thursday: 5.5 hours, Friday: 10.25 hours. 5 + 3.5 + 7.75 + 5.5 + 10.25 = 32 hours total workedChris: Monday: 6.5 hours, Tuesday: 7.25 hours, Wednesday: 9.5 hours, Thursday: 3.5 hours, Friday: 3.5 hours. 6.5 + 7.25 + 9.5 + 3.5 + 3.5 = 30.25 hours totalWe have now calculated the total hours for each person. You can therefore fill in the column of total hours, starting from the top, with 37.25 hours, then 32 hours, and finally 30.25 hours.
The final step is to calculate the total pay for each person.As I stated earlier, the only thing needed to do to find the total pay is to multiply the total hours my the rate per hour.
Sue: $16.50 per hour, 37.25 hours. 16.50 * 37.25 = $614.625, rounds up to $614.623Bob: $11.25 per hour, 32 hours. 11.25 * 32 = $360 dollarsChris: $14.50 per hour, 30.25 hours. 14.5 * 30.25 = 438.625, rounds up to $438.63Now we have all our solutions. For the total hours column, top to bottom: 37.25 hours, 32 hours, 30.25 hours. For the total pay column, top to bottom: $614.623, $360, $438.63Hope this helped!In Bluepoint, the average low temperature for January was 40 °F. The average low in February was 27% lower.

In order to answer this question, you must convert each number into 3 different fractions. This can be done by multiplyhing the number by the denominator (The denominator is the bottem part of the fraction) as you go up, for example, for 2 , you can make it into a 4/2, due to the denominator being 2, you multiply it by 2, and there you go, you made a fraction that equals the number. You can do this with the rest of these, although for number 11, its pretty much the same thing, just by dividing the new denominator with the old one then multiplying that new number by the numerator to get your fraction.

which function in the vertex form is equivalent to f(x)=x^2+6x+3
Answer:
B. f(x) = (x + 3)2 − 6
Step-by-step explanation:
Answer:
[tex]f(x)=(x+3)^2-6[/tex]
Step-by-step explanation:
We have been given a function [tex]f(x)=x^2+6x+3[/tex]. We are asked to find the function equivalent to our given function in vertex form.
To convert our given function in vertex form, we need to complete the square for our given function as:
Add and subtract [tex](\frac{b}{2})^2[/tex] from equation:
[tex](\frac{b}{2})^2=(\frac{6}{2})^=3^2=9[/tex]
[tex]f(x)=(x^2+6x+9)+3-9[/tex]
[tex]f(x)=(x^2+2\cdot 3x+3^2)-6[/tex]
[tex]f(x)=(x+3)^2-6[/tex]
Therefore, the [tex]f(x)=(x+3)^2-6[/tex] is equivalent to our given function in vertex form.
