Answer:
The amount of time Jill spent to do her homework
= 9 1/2 hours. which equals to 570 minutes.
Which means, the amount of times Jack needed to do his is
= 570 minutes x 1.5
= 855 minutes which equals to 14 1/4 hours
hope this helps
Answer:
Step-by-step explanation:
1) Time spent by Jack = Time spent by Jill * 1 1/2
[tex]= 9\frac{1}{2}*1\frac{1}{2}\\\\=\frac{19}{2}*\frac{3}{2}\\\\=\frac{19*3}{2*2}\\\\=\frac{57}{4}\\\\=14\frac{1}{4} hours[/tex]
2) Time spent by Jill = Time spent by Jack ÷ 1 1 /2
= 18 1/4 ÷ 1 1/2
= 73/ 4 ÷ 3/2
[tex]= \frac{73}{4} * \frac{2}{3}\\\\=\frac{73}{2}*\frac{1}{3}\\\\=\frac{73*1}{2*3}\\\\=\frac{73}{6}\\\\=12\frac{1}{6} hours[/tex]
3) Third number = Sum of three numbers - Sum of two numbers
Sum of two numbers = [tex]8\frac{2}{3}+8\frac{1}{6}\\[/tex]
[tex]= \frac{26}{3} +\frac{49}{6}\\\\=\frac{26*2}{3*2}+\frac{49}{6}\\\\=\frac{52}{6}+\frac{49}{6}\\\\=\frac{52+49}{6}\\\\=\frac{101}{6}\\[/tex]
Third number = 22 8/15 - 101/6
[tex]= \frac{338}{15}- \frac{101}{6}\\\\= \frac{338*2}{15*2}- \frac{101*5}{6*5}\\\\= \frac{676}{30}- \frac{505}{30}\\\\= \frac{676-505}{30}\\\\= \frac{171}{30}\\\\=5 \frac{21}{30}\\\\= 5 \frac{7}{10}[/tex]

Ahmed recorded the temperature outside his window one morning. On the second day, the temperature went up 7 degrees. On the third day, the temperature went down 10 degrees. On the fourth day, the temperature went down 6 degrees, and it was 1°F.What was the temperature on the first day?
Answer:
[tex]-2^{\circ}\text{F}[/tex]
Step-by-step explanation:
Let [tex]x[/tex] be the temperature on the first day
Second day temperature
[tex]x+7[/tex]
Third day temperature
[tex]x+7-10[/tex]
Fourth day temperature was [tex]1^{\circ}\text{F}[/tex]
[tex]x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}[/tex]

3. Determine whether these two lines are parallel, perpendicular, or neither. 1 point
8x + y = 7, 4x + 3y = 12 *
parallel,
perpendicular or
neither
Answer:
The two lines are neither
Step-by-step explanation:
Parallel lines have equal slopes and different y-interceptsPerpendicular lines have a product of their slopes = -1The slope of a line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]∵ The equations of the lines are
8x + y = 7 ⇒ 1st4x + 3y = 12 ⇒ 2nd∵ In the 1st equation a = 8 and b = 1
∴ m1 = [tex]\frac{-8}{1}[/tex] = -8
∴ The slope of the 1st line is -8
∵ In the 2nd equation a = 4 and b = 3
∴ m2 = [tex]\frac{-4}{3}[/tex]
∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]
→ By using the facts above
∵ m1 ≠ m2
∴ The two lines are not parallel
∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]
∴ m1 × m2 ≠ -1
∴ The two lines are not perpendicular
∴ The two lines are neither parallel nor perpendicular

If m<2 = (2x)° and m<5 = (x+6)°, find the value
of ‘x’ and the m<4.
Answer:
x = 58
[tex] m\angle 4 = 116\degree [/tex]
Step-by-step explanation:
[tex] m\angle 2 = m\angle 6..... (1)\\(alternate \: \angle s) \\\\
m\angle 5 + m\angle 6 = 180\degree \\(linear \: pair\: \angle s) \\\\
\therefore m\angle 6 = 180\degree-m\angle 5..... (2)\\\\[/tex]
From equations (1) & (2)
[tex] m\angle 2 =180\degree-m\angle 5\\\\
\therefore (2x)\degree =180\degree-(x+6)\degree \\\\
\therefore (2x)\degree +(x+6)\degree =180\degree\\\\
\therefore (2x+x+6) \degree =180\degree\\\\
\therefore (3x+6) \degree =180\degree\\\\
3x + 6 = 180\\\\
3x = 180-6\\\\
3x = 174\\\\
x = \frac{174}{3} \\\\
\huge \purple {\boxed {x = 58}} \\\\
\because m\angle 4 = m\angle 2\\(corresponding \: \angle s) \\\\
\therefore m\angle 4 = (2x)\degree \\\\
\therefore m\angle 4 = (2\times 58)\degree \\\\
\huge \orange {\boxed {\therefore m\angle 4 = 116\degree}} [/tex]

These two triangles are similar what is the measure of angle M?
Answer:
30
Step-by-step explanation:
We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:
180=102+48+m
180=150+m
30=m
Answer:
A. 30 degrees
Step-by-step explanation:
They are similar aka the same or congruent and since you know all three angles you just match them up.
9x + 11 = 110
what is x ?
Answer:
x = 11, lucky you, this stuff is easy
Step-by-step explanation:
110 - 11 = 99
9 x 11 = 99
99 + 11 = 110
Answer:
x = 11
Step-by-step explanation:
9x + 11 = 110
- Pass the 11 to the other side of the equation (grouping similar terms) and then perform the following operation:
9x = 110 - 11
9x = 99
- Now we have to obtain x by dividing 9 on both sides of the equation:
(9/9)x = 99/9
x = 99/9, which is divisible by 11.

In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches. There are 24 students in the cafeteria. How many students are eating lunches other than salads or sandwiches?
Answer:
Step-by-step explanation:
first, you would want to find the common denominator
3/8 (salads) = 3/8
1/4 (sandwiches) = 2/8
add them together to find out how much students and eating either salads or sandwiches
3/8 + 2/8 = 5/8
this means 5/8 of 24 students are eating either salads or sandwiches
24 students = 24/24 as a fraction
find the common denominator of 5/8 and 24/24
24/24 = 24/24
5/8 = 15/24
the final answer would be that 15 students out of 24 are eating a lunch other than a salad or sandwich
The number of people eating lunches other than salads or sandwiches is 3.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches.
So, The number of people eating salads is (5/8)×24 = 15.
And the number of people eating sandwiches is (1/4)×24 = 6.
Therefore, The number of people eating lunches other than salads or sandwiches is (24 - 15 - 6) = 3.
