-¼x = -4 / · (-4)
x = 16
is 1/4 bigger than 3/5
Answer:
No.
Step-by-step explanation:
If you plug both fractions into a calculator, you will get:
1/4 = 0.25
3/5 = 0.60
Since 25 is less than 60, 1/4 is not greater than 3/5.

levi finds a skateboard that sells 139.99. the store charges 6% sales tax about how much money will he have to spend for his skateboard?
The amount Levi spends on this skateboard is $148.39.
Tax is an amount levied on goods and services by the government. Taxes increases the price of goods and services.
The amount Levi spends on this skateboard = value of the tax + cost of the skateboard
value of the tax = 6% x $139.99
0,06 x $139.99 = $8.40
The amount Levi spends on this skateboard = $8.40 + $139.99 = $148.39

How to add rational expressions.
Frank practised for 4 hours and 35 minutes. If he stopped practising at 9:17 p.m, what time did he start practising?
4:42 p.m
You start with 9:17 and you subtract 4 hours. That gives you 5:17. Now you have to subtract the remaining 35 minutes. To make things easy we can make 5:17, five o-clock. We can do this by subtracting 17 then you'll get five o-clock. Now you have another 28 minutes to subtract. 5:00 - 28 = 4:42. Then you add the p.m.
On a map, 2 inches represents 60 miles. If a line between two cities measures 9 inches, how many miles apart are they?
2 inches = 60 miles:
60 miles/ 2 inches = 30 miles per inch.
30 miles per inch x 9 inches = 270 total miles.
Answer: 270 miles

Again, no links please! and explanation is optional.
Answer:
Option B is correct.
Step-by-step explanation:
6 3/7 = 45/7
1 3/6 = 9/6 = 3/2
=> 45/7 - 3/2
=> 90/14 - 21/14
=> 69/14
=> 4 13/14
Therefore, Option B is correct.
A sports writer wants to see if a football filled with helium travels farther, on average, than a football filled with air. 11 footballs were filled with helium to the recommend pressure and 12 footballs were filled with air to the recommended pressure. The mean yardage for the helium filled footballs was 291 yards with a standard deviation of 4 yards. The mean yardage for the air filled footballs was 285 yards with a standard deviation of 2 yards. Assume the populations are normal with equal variances.
(a). Construct a 80% confidence interval for the mean difference in in yardage for the two types of footballs
Lower bound
(use 3 decimal places)
Upper bound

(b). What can you conclude about the sports writer's idea that helimum footballs travel farther, on average?
Solve each question with the quadratic formula
6a² + 10 = 0
I know the answer but I'm not to sure how imaginary roots work. I would really appreciate if someone could explain how imaginary roots work! :)
Answer:
[tex]\boxed{\sf a=\cfrac{\sqrt{15i} }{3}}[/tex]
[tex]\boxed{\sf a=-\cfrac{\sqrt{15i} }{3}}[/tex]
Step-by-step explanation:
[tex]\sf 6a^2 + 10 = 0[/tex]
We'll solve this equation using The Quadratic Formula:
[tex]\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac} }{2a} }[/tex]
[tex]\sf 6a^2 + 10 = 0[/tex]
Substitute 6: a, 0: b, 10: c
[tex]\longmapsto\sf a=\cfrac{0\pm\sqrt{0^2-4\times 6\times 10} }{2\times 6}[/tex]
→ Square 0
→ Multiply -4 * 6= -24
→ Multiply -24 * 10 = -240
[tex]\longmapsto\sf a=\cfrac{0\pm\sqrt{-240} }{2\times 6}[/tex]
→ Take the square root of -240:
→ Multiply 2 * 6= 12
Now, Separate solutions:
[tex]\longmapsto\sf a=\cfrac{0\pm 4\sqrt{15i} }{12}[/tex]
Now, Separate solutions:
First, solve the equation when ± is plus:
[tex]\longmapsto \boxed{\sf a=\cfrac{\sqrt{15i} }{3}}[/tex]
___
Now, solve it when ± is minus:
[tex]\longmapsto \boxed{\sf a=-\cfrac{\sqrt{15i} }{3}}[/tex]
__________________________________________
[tex]\sf\longmapsto 6a^2+10=0[/tex]
a=6b=0c=10[tex]\sf\longmapsto a=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex](This a is root of equation)
[tex]\sf\longmapsto a=\dfrac{-0\pm\sqrt{0^2-4(6)(10)}}{2(6)}[/tex]

The angle measurements in the diagram are represented by the following expressions
Answer:
∠ B = 45°
Step-by-step explanation:
∠ A and ∠ Bare alternate exterior angles and are congruent , then
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Then
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°

I need with this please! It due tonight.
Answer:
x = 17
Step-by-step explanation:
1. First, we should know that all angles in any triangle add up to 180°.
This means that x + 17 + 6x + 10 + 4x - 34 = 1802. (Solving)
Step 1: Simplify both sides of the equation.
[tex](x+6x+4x)+(17+10-34)=180[/tex] [tex]11x -7 = 180[/tex]Step 2: Add 7 to both sides.
[tex]11x - 7 + 7 = 180 + 7[/tex] [tex]11x = 187[/tex]Step 3: Divide both sides by 11.
[tex]\frac{11x}{11} =\frac{187}{11}[/tex] [tex]x = 17[/tex]Step 4: Check if solution is correct.
[tex](17)+17+6(17)+10+4(17)-34=180[/tex] [tex]17 + 17 + 102 + 10 + 68 - 34 = 180[/tex] [tex]214 - 34 = 180[/tex] [tex]180 = 180[/tex]Therefore, x = 17.
Answer:
x=17
Reasoning:
The three interior angles of a triangle will always have a sum of 180°. Thus, you could make an algebraic equality with this information.
[tex]6x+x+4x+17+10-34=180[/tex]
[tex]11x-7=180[/tex]
[tex]11x=187[/tex]
[tex]\frac{11x}{11} =\frac{187}{11}[/tex]
[tex]x=17[/tex]

r | 6 + 1 =9
please help me this is due tomorrow and it’s my last question!!
if you can’t tell what it says it says R divided by 6 plus one equals 9!
Step-by-step explanation:
[tex] \frac{r}{6 } + 1 = 9 \\ \frac{r}{6} = 9 - 1 \\ \frac{ r }{6} = 8 \\ r = 48[/tex]
Answer:
r = 48
Step-by-step explanation:
The goal is to get r on one side of the equation.
To do this do the same thing to both sides of the eqaution to keep it in balance.
r/6 + 1 = 9
Subtract 1 from both sides
r/6 = 8
multiply both sides by 6
r = 48
