Can anybody help me with these questions??
Answer:
The first one yes
The second one yes they are congruent
The third one yes because when you divided 34 by 27.2(34/27.2) =1.25, 23 by 18.4 (23/18.4)=1.25 and 31 by 24.8(31/24.8)=1.25 so they are proportional.

1+ 2/5 × 4/5 ÷ 1/2( these are fractions btw)
Answer:
41/25 or 1 16/25
Step-by-step explanation:
1 + 2/5 x 4/5 ÷ 1/2
do multiplication first
2/5 x 4/5 = 8/15
1 + 8/25 ÷ 1 /2
do division by multiplying by the reciprocal

Mode ??
Median ?? Mean??
explanation ;)
MEAN - add all the numbers = 4+6+2+6+9+3+5 =42
then you count have many numbers you got 7
after that you divided 7/42 = 6 that the mean or something call average:)
MEDIA - to find out was the meaning is you first make in order like youngest to oldest 2, 3, 4, 5, 6, 6, 9 and circle what numbers is on the middle that is 5.
listen if there even amounts of numbers you just circle the two numbers in the middle then add does two numbers and divide dy 2 ONLY IF IS EVEN
MODE- look for the two numbers they are the same 6
and that's the mode

Step-by-step explanation:
(4z +9) + ( 9y - 2) =180
4z + 9y = 173 ....... Equation 1
The angles of triangle = 180
We miss one angle and in opposite of that angle is 135 so
( 5y +5 +4z +9)+135 = 180
5y + 4z + 149 = 180
5y + 4z = 31 ....... Equation 2
Subtract between two equations 1 & 2
4y = 142
y = 142/4
y = 35.5

What is the best prediction of the amount of money earned when the lemonade stand has been open for 9 hours
Answer: $50
Step-by-step explanation: Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)
It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
[tex]log_b(\frac{1}{b^3})[/tex]
This can be written as,
= [tex]log_b1 - log_bb^3[/tex]
= 0 - 3 [tex]log_bb[/tex]
= 0 - 3 x 1
= 0 - 3
= -3
Thus,
The value is -3.

Which of the following expressions is equivalent to 810 x 9?
O (800 x 9) + (10 x 9)
O (81 x 9) + (10 x 9)
O (600+ 310) x 9
O
814 x 5
Answer:
(800 x 9) + (10 x 9)
Step-by-step explanation:
Find out what 810 x 9 is:
810 x 9 = 7290
Then see which expression has the same answer. Personally I'd check all of them, but luckily the first expression is the correct one so you don't need to go through the rest (since it only asks for one correct expression):
(800 x 9) = 7200
(10 x 9) = 90
7200 + 90 = 7290
Write the equation of a line through (-1,-5) parallel to 3x-y=5, and in slope intercept form
Answer:
y = 3x -2
Step-by-step explanation:
The general equation form is;
y = mx + b
where m is the slope and b is the y-intercept
For the equation given;
y = 3x -5
the slope from here is 3
If two lines are parallel, they have equal slopes
This mean that the slope of the line we want to calculate too is 3
Now we can use the point slope format to get the correct equation
y-y1 = m(x-x1)
y+ 5. = 3(x+ 1)
y = 3x + 3 -5
y = 3x -2

Two people compete in a five-mile go kart race. Person A travels 1/10 miles every 15 seconds while Person B travels 3/8 mile every 48 seconds. Who wins the race? What is the difference of the finish times of the competitors?
Answer:
a) Person B wins the race.
b) The difference in the finish times of the competitors is 110 s.
Step-by-step explanation:
a) We can find the time that takes Person A and B to finish the race:
Person A:
[tex] t_{F_{A}} = \frac{t_{A}}{d_{A}}*d_{T} [/tex]
Where:
[tex]t_{A}[/tex]: is the time of Person A = 15 s [/tex]
[tex]d_{A}[/tex]: is the distance of Person A = 1/10 miles [/tex]
[tex]d_{T}[/tex]: is the total distance = 5 miles [/tex]
[tex] t_{F_{A}} = \frac{15 s}{1/10 miles}*5 miles = 750 s [/tex]
Person B:
[tex] t_{F_{B}} = \frac{t_{B}}{d_{B}}*d_{T} = \frac{48 s}{3/8 miles}*5 miles = 640 s [/tex]
Hence, Person B wins the race.
b) The difference in the finish times is:
[tex] t_{F_{A}} - t_{F_{B}} = 750 s - 640 s = 110 s [/tex]
Therefore, the difference in the finish times of the competitors is 110 s.
