if you run for 4 hours at 8miles an hour and walk 8 hours at 2 miles an hour, how far will you you have gone at the end of 12 hours?
Answer:
48 miles
Step-by-step explanation:
run -- 4 hrs at 8 mph = 4 • 8 = 32 miles
walk -- 8 hrs at 2 mph = 8 • 2 = 16 miles
32 + 16 = 48 miles

Find 3/5 x 4/7 in simplest form
Answer:
3/5 * 4/7 = 12/35
you can find the answer by multiplying the numerator by the other numerator and the denominator by the other denominator
[tex]\frac{3}{5} \times \frac{4}{7}[/tex] in its simplest form is [tex]\frac{12}{35}[/tex]
To evaluate the given multiplication in its simplest form, we will find the product of the given two fractions.
First, let us write the given fractions properly
That is,
[tex]\frac{3}{5} \times \frac{4}{7}[/tex]
Now, we will carry out the multiplication operation
[tex]\frac{3}{5} \times \frac{4}{7} = \frac{3 \times 4}{5 \times 7}[/tex]
Then, we get
[tex]\frac{3}{5} \times \frac{4}{7} = \frac{12}{35}[/tex]
(NOTE: This is the simplest form as both the numerator and the denominator do not have a common factor)
Hence, [tex]\frac{3}{5} \times \frac{4}{7}[/tex] in its simplest form is [tex]\frac{12}{35}[/tex]

suryana bought 16 watches for rs 16000. At what rate should he sell the watches to gain rs 3200?
Answer:
Step-by-step explanation:
So if 16 watches is 16000 rs, then if you want to make 3200 more rs, your total from 16 watches should be 19200 (which is 16000+3200)
so the rate per watch should be 19200/16 = 1200
So it should be 1200rs/watch is the rate
Answer:
So if 16 watches is 16000 rs, then if you want to make 3200 more rs, your total from 16 watches should be 19200 (which is 16000+3200)
so the rate per watch should be 19200/16 = 1200

Angle 1 and Angle 2 are complementary. The measure of Angle 1 is 21
more than twice the measure of Angle 2. Find the measure of Angle 1
Since both angles are complementary, then Angle 1 + Angle 2 = 90°
Using algebra,
let Angle 2 be X and Angle 1 be (2X + 21°)
Now we have an equation of,
( 2X + 21 ) + X = 90°
step 1 : open up the brackets first.
step 2 : bring 21° to the other side (rmb to flip the sign)
step 3 : bring the 3 over n it becomes " ÷3 "
( 2X + 21° ) + X = 90°
2X + 21° + X = 90°
3X = 90° - 21°
X = ( 90° - 21° ) ÷ 3
= 23°
Sub X=23° into Angle 1 ( 2X + 21° ),
2(23°) + 21° = 67°
Therefore,
Angle 1 = 67°

Answer:
It goes in one direction and indefinitely.
It consist one endpoint.
Step-by-step explanation:
A ray is a straight line that emerges out of a start point and moves in a direction. The line begins with the start point and moves in one direction. The start point and the other side are named with capital letters. It is denoted by writing the two letters and placing an arrow above the letters. There is no endpoint in a ray.

This question is about how transformations can affect graphs.
First, we'll want to get rid of that -4 on the function of F.
So we can reflect the function over the y-axis and then compress it by a factor of 4 to make the graph [tex]x^2[/tex].
Then we can move the graph over to the left 3 because the c value is positive, meaning that we move the graph over to the left.
Finally, we can move the function of by [tex]\frac{2}{3}[/tex] because the d value is positive, meaning that we move the graph up.
Hope this helps.

13y + 24 = 180
13y = 156
y = 12
13(12) - 14 = 156 - 14=142

Step-by-step explanation:
To solve this we need to do the operations in the brackets first. We should start with the innermost brackets. Then, we work our way outwards. To show my working out I will use an asterisk (*) for multiplication to not confuse X as a variable.
8*{[(7 + 4) * 2] - [(11 - 7) * 4]}

We have to arrange the given numbers in the order from least to greatest.
Numbers are [tex]\sqrt{64},8\frac{1}{7},8.1414..., \frac{15}{2}[/tex]
1). [tex]\sqrt{64}=8[/tex]
2). [tex]8\frac{1}{7}=\frac{57}{7}=8.143[/tex]
3). 8.1414....

Jayden’s snow cone machine makes 3 snow cones from 0.5 pound of ice. How many snow cones can be made with 5 pounds of ice ?
Answer:
30 snow cones.
Step-by-step explanation:
3 snow cones per 0.5 pounds of ice
0.5 pounds of ice x 10 = 5 pounds of ice
3 snow cones X 10 = 30 snow cones.
Answer:
30
Step-by-step explanation:
0.5 pounds of ice = 3 cones.
1 pound = 6 cones.
but we need to find how much 5 pounds will make.
1 pound = 6 cones.
times both sides by 5=
5 pound= 30 cones.
Which graph shows the solution of the system of equations?
What is the value of y?
Answer:
26
Step-by-step explanation:
We know that the entire angle measures 66 degrees.
Therefore, angle y plus 40 degrees must equal 66.
In an equation:
[tex]y+40=66[/tex]
To solve for y, subtract 40 from both sides:
[tex]y=26\textdegree[/tex]
So, the measure of angle y is 26 degrees.
And we're done!
Answer:
26°
Step-by-step explanation:
The angle with 66° which is shown with a red line is the sum of y and 40° so to find the value of y
we subtract 40 from 66 which gives us result as 26°.
los números reales se representan por
Los números reales están representados por números racionales e irracionales.
Un número racional es un número real que se puede formar dividiendo dos números enteros (un número entero es un número sin parte fraccionaria). La palabra viene de "ratio".
Un número irracional es un número real que NO se puede hacer dividiendo dos números enteros (un número entero no tiene parte fraccionaria). "Irracional" significa "sin relación", por lo que no es un número racional.
