What is the value of y?

Answer:

126.25

Step-by-step explanation:

take 8.75 and multiply by 8 =70

take 8.75+2.50=11.25

11.25x5=56.25

56.25+70=126.25

Answer:

A

Step-by-step explanation:

"17 less than twice a number" is 2n - 17

"No more than 35" is [tex]\leq[/tex] 35

2n - 17 [tex]\leq[/tex] 35

Answer:

The radius is 5

Step-by-step explanation:

[tex]r^{2}[/tex] = [tex]\frac{78.5}{3.14}[/tex]

[tex]r^{2}[/tex] = 25

r = [tex]\sqrt{25}[/tex]

r = 5

hence the answer is 5

Answer:

Your age is 97 years old.

Step-by-step explanation:

Let x be age.

500 - 4x = 112

-4x = -388

x = 97

Answer:

length = 37

Step-by-step explanation:

w= x

l= 3x + 1

to get the perimeter you need to add all sides.

x + x + 3x + 3x + 1 + 1 = 98

8x + 2 = 98

8x = 96

x = 12

To get the length plug in the value of the x to 3x + 1.

length = 3(12) +1

length = 37

Answer:

B = 180 - 85 = 95

∠ABC = 95

Step-by-step explanation:

Answer:

12.8

Step-by-step explanation:

subtract each leg from the total distance of 37.9. 37.9 - 12.3 - 7.6 - 4.2 = 12.8

Answer: Z and 96 are vertical angles so they equal each other. The other angle makes a straight line with the 96 degree angle so subtract from 180 to find the measure of that angle is 84. Set the expression equal to 84 and solve.

Answer:

62/amount of friends= each present

Step-by-step explanation:

Answer:

62 divide by the number of friends present

h (t) = -4t^2 + 24t = -4 (t² - 6t)

                           = -4 [(t - 3)² - 3²]

                           = -4 (t - 3)² + 36

max (3 ; 36)

(t - 3)² = t² - 2*t*3 + 3² = t² - 6t + 9

so it's why t² - 6t = (t - 3)² - 9

The maximum height of the projectile is 36 feet.

It is given that the projectile on a planet in our solar system at a given time t in seconds is represented by the function:

[tex]\rm h(t) = -4t^2+24t[/tex]  can be written as a function:

[tex]\rm h(t) = a(t-h)^2+k\\[/tex]

It is required to determine the maximum height of the projectile.

Maxima and minima of a function are the extrema within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.

The given function:

[tex]\rm h(t) = -4t^2+24t[/tex]  for the maximum height of the projectile differentiate the given function with respect to 't' and equate it to zero.

[tex]\rm h(t) = -4t^2+24t\\[/tex]

[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = \frac{\mathrm{d} }{\mathrm{d} x}(-4t^2+24t)\\[/tex]

[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = \frac{\mathrm{d} }{\mathrm{d} x}(-4t^2)+\frac{\mathrm{d} }{\mathrm{d} x}(24t)\\[/tex]

[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = -8t+24\\[/tex]

[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = 0 \Rightarrow-8t+24=0\\[/tex]

[tex]\rm -8t+24=0\\\rm t= 3 \ sec[/tex]

Here,  [tex]\rm \frac{\mathrm{d}^2 }{\mathrm dx^2} \leq 0[/tex]  

It means that at t=3, we get the maximum height of the projectile.

[tex]\rm h(3)= -4(3)^2+24(3)\\\rm h(3) = -36+72\\\rm h(3)= 36 \ Feet[/tex]

Thus, the maximum height of the projectile is 36 feet.

2x + 10 = 3x + 16

2x - 3x = 16 - 10

x = 6

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

Given the following question:

[tex]2(x+5)=3(x+6)[/tex]

To find the answer we need to expand the equation by using the distribution property, use inverse operations by subtracting or adding on both sides, and of course simplify if needed.

[tex]2(x+5)=3(x+6)[/tex]
[tex]2(x+5)=2x+10[/tex]
[tex]3(x+6)=3x+18[/tex]
[tex]2x+10=3x+18[/tex]
[tex]10-10=0[/tex]
[tex]18-10=8[/tex]
[tex]2x=3x+8[/tex]
[tex]3x-3x=0[/tex]
[tex]2x-3x=-x[/tex]
[tex]-x=8[/tex]
[tex]-x\div-x=x[/tex]
[tex]8\div-1=-8[/tex]
[tex]x=-8[/tex]

Your answer is "x = -8."

Step-by-step explanation:

4/3=1.3333333... it keeps repeating so it cannot be rational. Same problem with 19/9 (equials 2.111111...)

pi is a number that never ends therefore it is not rational.

Answer:

[tex]y=-\frac{1}{6}x-1[/tex]

Step-by-step explanation:

In order to solve this problem we can start by finding the slope of the perpendicular equation. We can do this by finding the slope of the equation that passes through the two points provided by the problem.

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

so we input the two points (5,-8) and (7,4) to get:

[tex]m=\frac{4-(-8)}{7-5}[/tex]

so  

m=6

next, we find the negative reciprocal to get the slope of the perpendicular line, so we get:

[tex]m=-\frac{1}{6}[/tex]

Now we need to find one point that the line passes through.

we can find that point by using the midpoint formula:

[tex]x=\frac{x_{2}+x_{1}}{2}[/tex]

[tex]y=\frac{y_{2}+y_{1}}{2}[/tex]

so we get:

[tex]x=\frac{7+5}{2}=6[/tex]

[tex]y=\frac{4-8}{2}=-2[/tex]

So the point is (6,-2)

So now we can find the equation of the line by using the point-slope form of the linear equation:

[tex]y-y_{1}=m(x-x_{1})[/tex]

and substitute the point and the slope into the equation:

[tex]y-(-2)=-\frac{1}{6}(x-6)[/tex]

and solve for y:

[tex]y=-\frac{1}{6}x+1-2[/tex]

[tex]y=-\frac{1}{6}x-1[/tex]

which will be our answer.

Answer: 2/3 feet

So, we have the following equation...

[tex]3.25+3/10=(?)[/tex]

Lets turn the fraction into a decimal.

Here's how...

Therefore, [tex]3/10=0.3[/tex].

Next, lets add our new decimal with 3.25.

[tex]3.25+0.3=3.55[/tex]

This gives us our final answer... [tex]3.55[/tex].

Answer:

Sydney is 76.

Step-by-step explanation:

Why?

88 - 12 = 76

If Devaughn is 12 years older and the sum of their ages is 88, Sydney is 76. When you add 12 to 76, you get 88. 88 is the sum of their ages.
