PLEASE HELP ASAP IM SPENDING POINTS THAT TOOK ME SO LONG TO GET How much time will Alex need to walk to his school, which is 2 1 4 miles away from his house, if he would walk with the speed of 2 mph
Answer:
1 1/8 hours
Step-by-step explanation:
The relationship between time and speed and distance is ...
time = distance/speed
Then Alex's time is ...
time = (2.25 mi)/(2 mi/h) = 1.125 h
It will take Alex 1 1/8 hours to walk to school at 2 mph.

Write an equation for the description . The length of a rectangle is twice its width . The perimeter of the rectangle is 122 feet.
Answer:
122 = 2(2w +w)
Step-by-step explanation:
If we let w represent the width of the rectangle, then 2w is the length of it. The perimeter is twice the sum of length and width.
P = 2(L+W)
122 = 2(2w +w) . . . . an equation for the description

Irina wants to tile her floor using the translation shown below. Which is the rule for this translation? T–3, 2(x, y) T2, –3(x, y) T3, 2(x, y) T–2, 3(x, y)
Answer:
The answer is A, -3.2(x y).
Step-by-step explanation:
I thought the answer was D but I took the test and the answer ended up being A. (Brainliest?)
The rule for this translation is: T-3.2(x y). (Option A). This rule states that the original dimensions (ABCD) must move -3 units to the left and 2 units up to form A'B'C'D'.
What is a translation?Where tach point in a figure is moved the same distance in the same direction using a sort of transformation, this is known as translation.
Thus, examining the position of the old shape and the new, it is correct to indicate that the right translation given the coordinates is option A.

"To find the area of a square room, Gordon must square the length of one side. The length of one side of room A is 1 ¼ yards. The length of one side of room B is 6 yards. What is the area of both rooms together?"
The correct answer is 37 ⁹/16
I did the math, and wrote the expression as: (1 ¼)² + 6². but still getting it wrong.....
also should I always convert a mixed number before using it's exponent???
Answer:
see explanation
Step-by-step explanation:
The sum of the areas of the 2 rooms is
(1 [tex]\frac{1}{4}[/tex] )² + 6² ← change the mixed number to an improper fraction
= ([tex]\frac{5}{4}[/tex] )² + 6²
= [tex]\frac{25}{16}[/tex] + 36
= 1 [tex]\frac{9}{16}[/tex] + 36
= 37 [tex]\frac{9}{16}[/tex]

HELP!!! Will give brainliest!!! How do you slove a two step equation with fractions involved?
I hope that this is what you are looking for
Step-by-step explanation:
Let's take the following question as an example,
[tex]\frac{2}{3} x-\frac{1}{4} = \frac{1}{6}[/tex]
Start by adding 1/4 to both sides.
[tex]\frac{2}{3} x - \frac{1}{4} + \frac{1}{4} = \frac{1}{6} + \frac{1}{4}[/tex]
[tex]\frac{2}{3}x = \frac{1}{6}+ \frac{1}{4}[/tex]
To add both 1/6 and 1/4 together we must have a common denomitor.
The common denominator for 1/6 and 1/4 is 12
[tex]\frac{2}{3}x = (\frac{1}{6}*\frac{2}{2} ) + (\frac{1}{4}*\frac{3}{3} )[/tex]
Multiple to get the common denomiators
[tex]\frac{2}{3}x = (\frac{2}{12}) + (\frac{3}{12} )[/tex]
Now we can add the fractions.
[tex]\frac{2}{3}x = \frac{5}{12}[/tex]
To get the x by itself we can either multiple by the reciprobcal of 2/3 or multiple by 3 and then divide by 2
[tex](\frac{3}{2} )* \frac{2}{3} x = (\frac{5}{12})(\frac{3}{2})[/tex]
The left side will become x as 3/2 and 2/3 cancel each other out
[tex]x = (\frac{5}{12}) (\frac{3}{2})[/tex]
Multiple the right side to get a value for x
[tex]x = \frac{15}{24}[/tex] or [tex]x = \frac{5}{8}[/tex]
If you notice we can simplfy the fraction to 5/8

help!! BRAINLIEST!The outside temperature at midnight today in Polina’s hometown was 18 degrees Fahrenheit. The temperature increases by 1.2 degrees Fahrenheit each hour over the next 15 hours. Polina’s school does not send students outside for recess if the outside temperature is 32 degrees Fahrenheit or lower. Recess at her school always starts on the half hour or hour. Which statement is true about recess at Polina’s school?
Only students who have recess at 11:00 a.m. or later may go outside.
Only students who have recess at 11:30 a.m. or later may go outside.
Only students who have recess at 12:00 p.m. or later may go outside.
Only students who have recess at 12:30 p.m. or later may go outside.
Answer:
Only students who have a recess at 12:00 pm or later may go outside
Step-by-step explanation:
it is 18 degrees at midnight and the temp. increases 1.2 every hour.
so 1.2 times 12 hours equal 14.4
add 14.4 to 18 drgrees equal 32.4
g Researchers studied 208 infants whose brains were temporarily deprived of oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly assigned babies to either usual care or to a whole-body cooling group. The goal was to see whether reducing body temperature for three days after birth increased the rate of survival without brain damage. What is the response variable
Answer:
The rate of survival without brain damage
Step-by-step explanation:
The response variable (or dependent variable) is the variable that is measured and which depends on other variables. In this experiment, the researchers are investigating the impact of reducing body temperature on rate of survival without brain damage. The variable that they were 'measuring' was the rate of survival without brain damage, which depended on the variable of reducing body temperature, therefore the response variable here is the 'rate of survival without brain damage.'

4 (-2×+9) = - 2 (3×-7)
Answer:
Step-by-step explanation:
4(-2x + 9) = -2(3x -7) {use distributive rule}
4*-2x + 4*9 = -2*3x - 7*(-2)
-8x + 36 = -6x + 14
Subtract 36 from both sides
-8x + 36 - 36 = -6x + 14 -36
-8x = -6x - 22
Add 6x to both sides
-8x + 6x = -6x +6x - 22
-2x = -22
Divide both sides by (-2)
-2x/-2 = -22/-2
x = 11
Which point on the graph could represent the ratio of 2 white flowers for every 3 pink flowers that will be in one row of Molly’s garden?
Answer: It’s B
Step-by-step explanation:
I just did the quiz
Answer:
The answer would be B
Step-by-step explanation:
take a look at your question.
If you look at the x axis you can see that it is 12 but c is also that.
Now take a look at the y axis, you can see that the letter B is connected to 18.
If you remember your previous problems you would remember that that was an answer (12, 18). But for those who do not remember you can multiply 2x6(which you got your 12 from) and 3x6 ( which is where the 18 is from)
So there for you are left with the answer B.

17 cm
The missing length is
cm.
(Round to one decimal place as needed.)
Answer:
it depends
Step-by-step explanation:
If 17 is the hypotenuse
[tex]c=17\\\\b=12\\\\a=?\\\\c^{2} =a^2+b^2\\\\17^2=a^2+12^2\\\\17^2-12^2=a^2\\\\(17-12)(17+12)=a^2\\\\5(27)=a^2\\\\a=\sqrt{9*3*5} \\\\a=3\sqrt{15} \\\\a=11.6[/tex]
if you are looking for the hypotenuse
[tex]a=17\\\\b=12\\\\c=?\\\\a^2+b^2=c^2\\\\17^2+12^2=c^2\\\\289+144=c^2\\\\433=c^2\\\\c=\sqrt{433} \\\\c=20.8[/tex]
