Answer:

20 chairs

Step-by-step explanation:

Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.

800 = 320 + 24s  ... subtract both sides by 300

500 = 24s ... divide both sides by 24

20.83 = s

Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.

Answer:

The librarian can buy a maximum of 20 chairs to stay within the budget.

Step-by-step explanation:

The total budget is:

T = 800

From that budget, he spends 320 on desks (D), so he has the remaining amount to buy chairs (C):

[tex] C = 800 - 320 = 480 [/tex]

Since each chair costs 24, and he has 480 he can buy the following number of chairs:

[tex] n = \frac{C}{24} = \frac{480}{24} = 20 [/tex]

Therefore, the librarian can buy a maximum of 20 chairs to stay within the budget.

I hope it helps you!  

Answer:

For the time interval 0 to 2 the ball is in the air.

Select the options according to this.

Step-by-step explanation:

The equation should be [tex]h(t)=-16t^{2} -30t+124[/tex]

Let's find the x intercepts to answer this question.

To find x intercept where the h(t) is 0.

[tex]-16t^{2} -30t+124=0[/tex]

Solve the equation for t.

Use quadratic formula to solve the equation.

a=-16

b=-30

c=124

[tex]x=\frac{-b+/- \sqrt{b^{2}-4ac } }{2a}[/tex]

Plug in the values of a, b and c into the formula

[tex]x=\frac{30+/-\sqrt{(-30)^{2}-4(-16)(124) } }{2(-16)}[/tex]

Simplify it

[tex]x=\frac{30+/- \sqrt{900+7936} }{-32}[/tex]

[tex]x=\frac{30+/-\sqrt{8836} }{-32}[/tex]

[tex]x=\frac{30+/-94}{-32}[/tex]

Simplify it to get two values for x

[tex]x=\frac{30+94}{-32} =-3.875\\\\x=\frac{30-94}{-32} =2[/tex]

x can not be negative, here x represents time t.

So, it starts from 0 and remains in the air for 2 seconds.

Answer:

9 more weeks

Step-by-step explanation:

because if you do 740-500 you get 240

so then i divide 240 by the money per week (25) and

get 9.6 so it is 9 weeks

Answer:

Can you reformat?

So far, 0 is a solution to none of these.

Answer:

1. nope

2. not sure

3. nope

Step-by-step explanation:

1.

-3(y - 1) > 3

-3y + 3 > 3

-3y > 0

y > 0

0 is not a solution since 0 is not greater than 0

2.

I'm not sure what this question means, is there a [tex]\geq or \leq[/tex] between the 4 and the 0?

3.

y + 8 < 2y + 8

8 < 2y - y + 8

8 - 8 < y

0 < y

0 is not a solution because 0 is not greater than 0

im confused- I prolly got something wrong.

Answer:

x = -3 (yes that's negative 3)

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Answer:

[tex] \sf \: x = - 3[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -6 + x + 4 = -5

Then the value of x will be,

→ -6 + x + 4 = -5

→ x + (-6 + 4) = -5

→ x + (-2) = -5

→ x - 2 = -5

→ x = -5 + 2

→ [ x = -3 ]

Hence, the value of x is -3.

Answer:

y=4x+11

Step-by-step explanation:

multiply 4 into the parentheses to get y-3=4x+8 then invert -3 so add three to both sides to get rid of it so instead of +8 its +11 so now its y=4x+11 and slope intercept is y=mx+b, so 4 is m, slope, and 11 is b, the y intercept i hope that helps

Answer:

Use SOH-CAH-TOA method and figure out which sign you need. SOH- Sin, CAH- Cos, TOA- Tan.

Also,

SOH- opposite/hypotenuse

CAH- adjacent/hypotenuse

TOA- opposite/adjacent

Look at the angle and see which terms you have already. For example, if you had opposite the angle and the adjacent side, you would choose tangent because its TOA. Hope that helps!

Answer:

we know that

volume of a grain silo=volume of a cylinder+volume of a hemisphere

volume of a grain silo=17000 ft³

volume of a cylinder=pi*r²*h

h=30 ft

volume of a cylinder=pi*r²*30----> 30*pi*r² ft³

volume of a hemisphere=(2/3)*pi*r³

so

17000=30*pi*r²+(2/3)*pi*r³-----> multiply by 3---> 51000=282.60*r²+6.28*r³

6.28*r³+282.60*r²-51000=0

using a graph tool

see the attached figure

the solution is  

r=11.942 ft-------> r=11.9 ft

the answer is

The radius of the silo is 11.9 ft

Answer: Domain is [1,3], Range is [304,391]

Step-by-step explanation:

Domain is just the x values the table has from lowest to highest. Period is the x values so domain is [1,3]

Range is the y values from lowest to highest the lowest y is 304 and highest is 391, so you use those two numbers to get [304,391]

Answer:

The probability is [tex]P(R) = 0.0583 [/tex]

Step-by-step explanation:

From the question we are told that

  The probability that selected adults are affected by virus is  p =  0.004

  The probability that adults are not affected by virus is  [tex]q= 1- p = 1-0.004 = 0.996[/tex]

    The sample size is  n =  15

 Generally from the question we are told that    

The probability that the combined sample tests positive is equal to the probability that  at least one person test positive for the  virus

So  

The probability that the combined sample tests positive for the​ virus is equal to  

  1- the probability that non of the adults selected tested positive for the virus

Generally the probability that  non of the adults selected tested positive for the virus is  

      [tex]P(k) = q^n[/tex]

=>    [tex]P(k) = q^{15}[/tex]

=>    [tex]P(k) = 0.996^{15}[/tex]

=>    [tex]P(k) =  0.9417 [/tex]

The probability that the combined sample tests positive for the​ virus is mathematically represented as

        [tex]P(R) = 1 - P(k)[/tex]

=>     [tex]P(R) = 1 - 0.9417 [/tex]

=>     [tex]P(R) = 0.0583 [/tex]
