-2^2(-5x+10)=100
Answer:
[tex]x=7[/tex]
Step-by-step explanation:
Hi there!
[tex]-2^2(-5x+10)=100[/tex]
Solve -2^2:
[tex]-4(-5x+10)=100[/tex]
Divide both sides by -4:
[tex]\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25[/tex]
Subtract 10 from both sides:
[tex]-5x+10-10=-25-10\\-5x=-35[/tex]
Divide both sides by -5:
[tex]\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7[/tex]
Therefore, x = 7.

Kennedy has a bag that contains strawberry chews, apple chews, and lime chews. She
performs an experiment. Kennedy randomly removes a chew from the bag, records
the result, and returns the chew to the bag. Kennedy performs the experiment 38
times. The results are shown below:
A strawberry chew was selected 18 times.
A apple chew was selected 11 times.
A lime chew was selected 9 times.
Based on these results, express the probability that the next chew Kennedy removes
from the bag will be a flavor other than apple as a decimal to the nearest hundredth.
Answer:
0.71
Step-by-step explanation:
Based on what we see here, we can deterime the probability of each flavor being drawn.
Apple: 11/38
Strawberry: 18/38
Lime: 9/38
So the probability of an apple NOT being drawn is 27/38. This is about 0.71.

Angles DUT and VUD sum to VUT. We can create an equation to model this.
DUT + VUD = VUT
Now, let's plug our values into the equation.
24x + 5 + 46 = 35x - 4
Simplify the left side.
24x + 51 = 35x - 4
Subtract 24x from both sides and add 4 to both sides.
55 = 11x
Divide both sides by 11.
5 = x
Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week

One hose can fill a small swimming pool in 65 minutes. A larger hose can fill the pool in 60 minutes. How long will it take the two hoses to fill the pool working together?
Step-by-step explanation:
1st horse time taken = 65 min/job; invert to get rate = 1/65 job/min
2nd horse time taken = 35 min/job ; invert to get rate = 1/35 job/min
Together Time taken = n min/job ; invert to get rate = 1/n job/min
------------------
Equation :-
Rate + Rate = together rate
1/65 + 1/35 = 1/n
-----------------------------
35n + 65n = 35*65
-----------------
100n = 2275
n = 22.75 minutes = 22 minutes 45 seconds

the perimeter of a rectangular tray is 60in the length of the tray is double the width of a tray determine the dimensions of the rectangular tray
Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in

Okay so, to solve this question we need to convert -3/5 to its decimal form.[tex] \large \sf - \frac{3}{5} = - 0.6 \\ [/tex]We can see that - 3/5 is equal to - 0.6 which is not equal to -0.4.So, - 3/5 & - 0.4 are not equal.Hey there!
Convert the fraction to decimals.
-3/5 = -0.6
-0.6 < -0.4
Hence, -3/5 is not equal to -0.4.

A regular square-based pyramid has a surface area of 33 m2. If its triangular faces have an area of 6 m2, what is the length of the base of the pyramid?
Answer:
First we can do 33 time 6
Step-by-step explanation:
The length of the base of the pyramid is 3 meters.
What is a square pyramid?A pyramid is a polyhedron that has a base and 3 or greater triangular faces that meet at a point above the base. A square pyramid is a pyramid with a square base, four triangular sides, five vertices, and eight edges.
For the given situation,
The surface area of the pyramid = 33 m^2
Area of triangular faces = 6 m^2
Let the base of the pyramid be b and the height be h.
The formula of area of triangle is
[tex]A = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6 = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6(2) = (b)(h)[/tex]
⇒ [tex]12 = (b)(h)[/tex]
The formula of surface area of square pyramid is
[tex]SA = b^{2}+2bh[/tex]
⇒ [tex]33=b^{2} +2(12)[/tex]
⇒ [tex]33-24=b^{2}[/tex]
⇒ [tex]b=\sqrt{9}[/tex]
⇒ [tex]b=3[/tex]
Hence we can conclude that the length of the base of the pyramid is 3 meters.

Together, two pipes can fill a tank in 3 hours.
One pipe alone can fill the tank in 5 hours.
How long does it take for the other pipe to
fill the tank alone?
Answer: 7.5 (h)
Step-by-step explanation:
Let say
a the outflow of the first pipe
b the outflow of the second pipe
T the volume of the tank.
x the time for filling with the second pipe
two pipes can fill a tank in 3 hours: a*3+b*3=T
One pipe alone can fill the tank in 5 hours : a*5=T
3*b=T -3a ==> 3b= 5a*3a=2a
b=2a/3
b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1
x=15/2 = 7.5 (hours)

Let y=|x|-2, where the domain is the set of integers from – 4 to 4.
What is the range?
i dont know i wish I could help.
Answer:
-2 to 2
Step-by-step explanation:
see there's the sign of absolute value around x
so even if we put a negative number in place of x we'll get a positive outcome.
for example,
if x = -4|x| = 4
if x = -3|x| = 3
and so on
so the actual domain of |x| reduces to => 0 to 4.
as you'll get the values of |x| in between 0 and 4 throughout -4 to 4.
where the smallest value is 0 and largest is 4.
for range,
I'll just put these smallest and largest values in place of x and solve for domain
at x = 0y= |0| - 2
y = -2
at x = 4y = |4| - 2
y= 4 - 2
y = 2
so, the range of the function becomes -2 to 2.
