3.25$ to wash the car.

60 seconds: 1 quarter

how many quarters is 3.25?

4 quarters per dollar. so it'd be 13 quarters, then do 13*60=how many seconds u got. 780 seconds. I think you can do 780/60

Answer:

129 [tex](1.3526)^{t}[/tex]

Step-by-step explanation:

Assuming N = [tex]ab^t[/tex]

t = number of years after 2011

N = number of wolves

When  t = 0 , N = 129

129 = [tex]ab^0[/tex]

a = 129

N = 129[tex]b^{t}[/tex]

When t = 2 , N = 236

therefore 236 = 129 [tex]b^{2}[/tex]

[tex]b^{2}[/tex]  = [tex]\frac{236}{129}[/tex]

therefore; b = 1.3526

Answer expressed in the form of a(b)^t.

129 [tex](1.3526)^{t}[/tex]

Answer:

The answer would be x=4.  

Step-by-step explanation: Step 1: Simplify both sides of the equation.

2x+3(5x−7)=47

2x+(3)(5x)+(3)(−7)=47(Distribute)

2x+15x+−21=47

(2x+15x)+(−21)=47(Combine Like Terms)

17x+−21=47

17x−21=47

Step 2: Add 21 to both sides.

17x−21+21=47+21

17x=68

Step 3: Divide both sides by 17.

17x/17=68

17x=68

x=4

Answer:

Step-by-step explanation:

Let us represent

The number of Box seats = x

The number of grandstand seats = y

The number of bleacher seats cost = z

A minor league baseball park has 6800 seats.

Hence,

x + y + z = 6800

Box seats cost $19, grandstand seats cost $9, and bleacher seats cost $4. When all seats are sold, the revenue is $61200.

Hence:

$19 × x + $9 × y + $4 × z = $61200

19x + 9y + 4 z = 61200

If the number of bleacher seats is 2 times the number of box seats

z = 2x

Hence we substitute

x + y + z = 6800

x + y + 2x = 6800

3x + y = 6800.... Equation 3

y = 6800 - 3x

For Equation 2, substituting 2x for z

19x + 9y + 4z = 61200

19x + 9y + 4(2x) = 61200

19x + 9y + 8x = 61200

27x + 9y = 61200...... Equation 4

Combining Equation 3 and 4

3x + y = 6800.... Equation 3

27x + 9y = 61200...... Equation 4

Note that:

y = 6800 - 3x

We substitute the above in Equation 4

27x + 9(6800 - 3x) = 61200

27x + 61200 - 27x = 61200

Box seats:_______ Grandstand seats:_______ Bleacher seats:______

Point and line segment are used to define a ray.

A ray is a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction.

A line extends infinitely in either direction but has no width and is one dimensional. A point is a 0-dimensional mathematical object with a location.

Answer:

Step-by-step explanation:

Hi there.

1a.  m C= 44 degrees

46+90= 136    180-136=44

1b.  m P= 60 degrees

10+110=120  180-120=60

For future reference, you can solve these with some simple addition. The sum of the angles in any triangle is 180, so add your two given pieces together and subtract it from that to get your missing measure.

2a. Lines a and b have a positive slope. You can tell because they are tilted to the right.

2b. Line d has a negative slope. It's tilted to the left.

(Line c's slope is neither positive or negative because it is zero)

3. x= 65

(I'm not so sure about this one, but I think the angle opposite 25 is also 25, and because of parallel rules the angle above 70 is 110. That means the angle above 110, inside the triangle, is 90. So, we have 90 and 25 and that means 65 is our remaining measure. I really hope this is correct. If you have some sort of notes sheet on the rules of parallel lines and their angle measures, that might be helpful)

Answer:

[tex][(1+i\sqrt{29}), (1-i\sqrt{29})][/tex], [tex][(1+i\sqrt{26}), (1-i\sqrt{26})][/tex], [tex][(1+i\sqrt{21}), (1-i\sqrt{21})][/tex],

[tex][(1+i\sqrt{14}), (1-i\sqrt{14})][/tex], and [tex][(1+i\sqrt{5}), (1-i\sqrt{5})][/tex].

Step-by-step explanation:

Given that two complex numbers have a product of 30 and the real part of the complex numbers are positive integers.

Let one complex number is [tex]a+ib[/tex] where [tex]a[/tex] is a positive integer and [tex]b[/tex] is a real number.

As the product of two complex numbers is a purely real number, so the other complex number must be the conjugate of the first complex number.

So, another complex number [tex]= a-ib[/tex]

As a product of both the numbers = 30

[tex]\Rightarrow (a+ib)(a-ib)=30 \\\\\Rightarroe a^2 - (ib)^2=30 \\\\\Rightarrow a^2 - (i^2b^2)=30 \\\\Rightarrow a^2 - (-1\times b^2)= 30[/tex] [as i^2=-1]

[tex]\Rightarrow a^2+b^2= 30 \\\\\Rightarrow b^2 = 30-a^2 \\\\[/tex]

[tex]\Rightarrow b=\pm \sqrt {30-a^2} \cdots(i)[/tex]

Now, as a is a positive integer, so by taking possible values of a, we can determine the values of b from the equation (i).

For [tex]a=1[/tex]

[tex]b=\pm \sqrt {30-1^2}=\pm \sqrt {29}[/tex]

The positive sign is for the one number and the negative sign is for the conjugate number (another number).

So, the 1st combination is [tex][(1+i\sqrt{29}), (1-i\sqrt{29})][/tex]

Similarly,

For [tex]a=2[/tex]

[tex]b=\pm \sqrt {30-2^2}=\pm \sqrt {26}[/tex]

So, the 2nd combination is [tex][(1+i\sqrt{26}), (1-i\sqrt{26})][/tex]

For [tex]a=3[/tex]

[tex]b=\pm \sqrt {30-3^2}=\pm \sqrt {21}[/tex]

So, the 3rd combination is [tex][(1+i\sqrt{21}), (1-i\sqrt{21})][/tex]

For [tex]a=4[/tex]

[tex]b=\pm \sqrt {30-4^2}=\pm \sqrt {14}[/tex]

So, the 4th combination is [tex][(1+i\sqrt{14}), (1-i\sqrt{14})][/tex]

For [tex]a=5[/tex]

[tex]b=\pm \sqrt {30-5^2}=\pm \sqrt {5}[/tex]

So, the 5th combination is [tex][(1+i\sqrt{5}), (1-i\sqrt{5})][/tex]

The higher integral value of [tex]a[/tex] is not possible for any real [tex]b[/tex].

Hence, the possible combinations of required numbers are

[tex][(1+i\sqrt{29}), (1-i\sqrt{29})][/tex], [tex][(1+i\sqrt{26}), (1-i\sqrt{26})][/tex], [tex][(1+i\sqrt{21}), (1-i\sqrt{21})][/tex],

[tex][(1+i\sqrt{14}), (1-i\sqrt{14})][/tex], and [tex][(1+i\sqrt{5}), (1-i\sqrt{5})][/tex].

Answer:

[tex] y = 2x - 5 [/tex]

Step-by-step explanation:

Find the slope using the points, (1, -3) and (3, 1):

[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-3)}{3 - 1} = \frac{4}{2} = 2 [/tex]

m = 2

Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in [tex] y = mx + b [/tex]

[tex] -3 = (2)(1) + b [/tex]

[tex] -3 = 2 + b [/tex]

Subtract 2 from both sides

[tex] -3 - 2 = 2 + b - 2 [/tex]

[tex] -5 = b [/tex]

[tex] b = -5 [/tex]

Plug in the value of m and b into the slope-intercept form equation, [tex] y = mx + b [/tex].

Thus:

[tex] y = 2x +(-5) [/tex]

✅[tex] y = 2x - 5 [/tex]

Given inequality is:

[tex]-4x+3<23[/tex]

Clare's error was in the last step where she multiplied the inequality by -4 to remove the minus sign with x. When an in equality is multiplied/Divided by a negative number then the sign of inequality is reversed. < is changed to > and > is changed to less than.

The answer must have been x > -5
