Answer:

10x+200[tex]\leq[/tex]375

Step-by-step explanation:

subtract 200 from both sides

10x[tex]\leq[/tex]175

divide both sides by 10

x[tex]\leq[/tex]17.5 cars

Answer:

(c) 9

Step-by-step explanation:

You can't have a repeated x-value in a function.

8 is taken by (8, 7)

7 is taken by (7,-6)

-4 is taken by (-4, 5)

9 is the only number that is not taken by any other point yet.

Remember that for a relationship to be a function it can't have repeated x-values. However, it doesn't matter to have the same x and y values!

Answer: C) 165 annual members

Step-by-step explanation:

Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.

Out of the 75 surveyed, the total number of those are:

= 9 + 12 + 3

= 24

That would give a percentage of:

= 24 / 75

= 32%

This means that the best estimate for those who will visit more than 3 times is 32%.

Out of the total number of 516, that is:

= 32% * 516

= 165 members

Step-by-step explanation:

número 500? Cálculos y verificación detallados. Introducción: 'Porcentaje (%)' significa 'de cien': ¿Cómo verificamos el resultado? Si 30% × 500 = 150 => Divida 150 entre 500 ... Nota: 100/100 = 100 ÷ 100 = 100% = 1. Calcule el valor porcentual: 150

Top and bottom:  (7.5in x 4in) = 30 in² each

Left and right sides:  (2.5in x 4in) = 10 in² each

Front and back:  (7.5in x 2.5in) = 18.75 in² each

Total area:  (58.75 in² ) x 2 = 117.5 in²

Answer:

b = 1/3

Step-by-step explanation:

Here, we want to solve for the value of b

From the question, we have that;

4^(3b-3) = 1/16

4^(3b-3) = 16^-1

4^(3b-3) = 4^2(-1)

4^(3b-3) = 4^-2

Since base are equal, equate the powers

3b - 3 = -2

3b = -2 + 3

3b = 1

b = 1/3

Answer:

x = 132 degrees

Step-by-step explanation:

To help explain, lets add some letters to designate those line intersections.

Starting at x, label that intersection O, then go up-right to that intersection and label that P, then go down-right to that intersection and label that Q, then go up-right and name that R, then go down-right and label that S, finally go right to that intersection and label that T.

Angle TRS = 12 degrees because  isosceles triangle so TRS = a = 12 degrees.

Angle RST = 180-12-12 = 156 degrees.

Angle QSR is supplementary to RST so it is 24 degrees.

Angle RQS = 24 degrees because isosceles.

Angle QRS = 180-24-24 = 132 degrees.

Angle PRQ = 180-12-132 = 36 degrees.

Angle PRQ = 36 degrees because isosceles.

Angle PQR = 180-36-36 = 108 degrees.

Angle PQO = 180-24-108 = 48 degrees.

Angle POQ = 48 degrees because isosceles.

Angle x = 180 -48 = 132 degrees because it is supplementary.

Answer:

(5, -2)

Step-by-step explanation:

Let's solve the first equation for x:  If x + y = 3, and if we subtract y from both sides, we get x = 3 - y.  Next, substitute 3 - y for x in the second equation:

3(3 - y) + 2y = 11, or

9 - 3y + 2y = 11

Combining like terms:  -3y + 2y = 11 - 9, or

-y = 2, or y = -2.

Then, from the equation x = 3 - y, which we found earlier,

x = 3 - (-2) = 5

Then the solution is (5, -2)

Answer:

8.4

Step-by-step explanation:

51.24 ÷ 6.1 = 8.4

Although, if you were dividing 6.1 by 51.24, you would have a totally different answer, the answer to 6.1 ÷ 51.24 = 0.119047619047619.

Answer:

It's 48. Heres why:

Step-by-step explanation:

Our equation, I believe, is 4[(12-8) + 2³]. We can do the operations in the parenthesis:

4[(4)+8] (12-8 = 4, and 2³ is 8). If we add 4 + 8, we get 12. Multiply 12 by 4, we get 48.

I dont know how to solve this but heres a suggestion: Use PEMDAS

Answer:

  $1,754.57

Step-by-step explanation:

If you put the amount in savings at the beginning of the year, then the balance after 7 years is ...

  A = P(1 +r)((1 +r)^7 -1)/r . . . . for payment P at annual rate r for 7 years

  15000 = P(1.05)(1.05^7 -1)/0.05 = 8.54911P

Then the amount P that needs to be saved is ...

  15000/8.54911 = P = 1754.57

You need to deposit $1,754.57 at the beginning of each year for 7 years to have a balance of $15,000 at the end of 7 years.

_____

If you wait until the end of the year to deposit the money, the amount will need to be 5% higher: $1,842.30.

Answer:

65°

Step-by-step explanation:

From the question,

The base angle of an isoceles triangle are equal.

Let the value of the base angles = x°

Sum of angle in a triangle = 180°

⇒ x°+x°+50° = 180°

⇒ 2x°+50° = 180°

⇒ 2x° = 180°-50°

⇒ 2x° = 130°

⇒ 2x°/2 = 130/2

⇒ x° = 65°.

Hence, the size of the other angles is 65°

The SOH CAO TOA identity is used to determine the acute angles of a right triangles. The terminal point of ø is (-1,0), what is tan ø is 0

Given the terminal point (-1, 0), the value of tanø is expressed as:

tanø = opposite/adjacent

tanø = y/x

From the coordinate given:

x = -1

y = 0

Substitute

tanø = 0/-1
tanø  = 0

Hence the terminal point of ø is (-1,0), what is tan ø is 0

Answer:

44 units² or 44 units squared

There really isn't a preference of units, like inches or meters, so you can add that in.

Step-by-step explanation:

Haha, this is what we're doing in class!

Okay, so the formula for a trapezoid is A= ½ (b1+b2) h

14= b1

8= b2

Add them... You get 22. Multiply that by the height, which is 4. You should get 88. Then divide by 2. You should get 44.

2. Calcuate the sum

Answer:

39 pounds

Step-by-step explanation:

1) 1/2 + 1/2 = 1 -> this means 2 crayons  equals 1 ounce

2) 96/2 = 48 -> 48 oz of crayons *oz means ounces*

3) 48 + 4 = 52 oz -> box + crayons = total weight of box of crayons

4) 52 * 12 = 624 oz

5) 624/16 = 39 lbs -> convert ounces to pounds
