A refrigerated truck leaves a rest stop traveling at a steady rate of 56 mi/h. A car leaves
same rest stop 1/4 hour later following the truck at a steady rate of 64 mi/h. How long after the truck leaves the rest stop will the car overtake the truck? Write an equation and solve
Answer:
Step-by-step explanation:
T=56t and C=64(t-.25)
64(t-.25)=56t
64t-16=56t
8t-16=0
8t=16
t=2 hours
Drag the symbol to complete the solution to this inequalities
Answer:
x ≤ 13.2.
Step-by-step explanation:
6 ≥ x/2.2
Multiply both sides by 2.2:
6 * 2.2 ≥ x
x ≤ 13.2.
The solution to the inequality is [tex]x \leq 13.2[/tex], the correct symbol used in blank is ≤.
To complete the solution to the inequality [tex]6 \geq \frac{x}{2.2}.[/tex]
Rearrange the inequality as follows:
[tex]\frac{x}{2.2} \le 6[/tex]
The solution to the inequality is:
[tex]x \leq 13.2[/tex]
Comparing the expression [tex]\frac{x}{2.2}[/tex] to 6, we can see that [tex]\frac{x}{2.2}[/tex] should be less than or equal to 6 in order for the inequality to hold true.
Therefore, the correct symbol to place in the blank is "≤" and solution is [tex]x \leq 13.2[/tex].

Step-by-step explanation:
We are given that
RQ=3 m
PQ=4 cm
RP=x cm
RS=13 cm
SP=y cm
We know that Pythagoras theorem

Write a ratio, in the simplest form and a percent for the shaded area (there's a 5x4 box and 6 cubes are shaded)
Answer:
[tex]\%Percent = 30 \%[/tex]
Step-by-step explanation:
Given
[tex]Shaded = 6\ cubes[/tex]
[tex]Box = 5\ x\ 4[/tex]
Required
Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
[tex]Box = 5\ x\ 4[/tex]
Express as multiplication
[tex]Box = 5\ *\ 4[/tex]
[tex]Box = 20[/tex]
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
[tex]\%Percent = \frac{Shaded}{Box} * 100\%[/tex]
[tex]\%Percent = \frac{6}{20} * 100\%[/tex]
[tex]\%Percent = \frac{6* 100}{20} \%[/tex]
[tex]\%Percent = \frac{600}{20} \%[/tex]
[tex]\%Percent = 30 \%[/tex]
30% were shaded

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by
combining the equations.
Answer:
(6,-7)
Step-by-step explanation:
subtract them:
-8x - 5y = -13
-4x - 5y = 11
you get
-4x = -24
so x = 6
plug x into the second equation:
-24 - 5y = 11
-5y = 35
y = -7
so your solution is (6,-7).
Answer:
Your solution is (6, -7).
Step-by-step explanation:
Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.
-8x - 5y = -13
-4x - 5y = 11
Let's change the second equation into one with one variable on each side.
-5y = 4x + 11
y = -4/5x - 11/5
Now, plug this into your first equation.
-8x - 5(-4/5x - 11/5) = -13
Distribute the -5 sign.
-8x + 4x + 11 = -13
Combine the like terms.
-4x + 11 = -13
-4x = -24
Isolate x by dividing both sides by -4.
x = -24/-4
x = 6
Now plug this back into either equation.
y = -4/5(6) - 11/5
Multiply.
y = -24/5 - 11/5
Subtract.
y = -35/5
Simplify.
y = -7
Your solution is (6, -7).
Check this by plugging in these values into the equation you have not checked yet.
-8(6) - 5(-7) = -13
-48 + 35 = -13
-13 = -13
Your solution is correct.
Hope this helps!

What are the solutions of 16p^2 - 64 = 0
Answer:
p = 2 or p = -2
Step-by-step explanation:
Solve for p over the real numbers:
16 p^2 - 64 = 0
Hint: | Factor constant terms from the left hand side.
16 p^2 - 64 = 16 (p^2 - 4):
16 (p^2 - 4) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 16:
p^2 - 4 = 0
Hint: | Using the quadratic formula, solve for p.
p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:
