What is the measure of the indicated angle?

Answer: 5n−16

Step-by-step explanation: Distribute:

=−11+(5)(n)+(5)(−1)

=−11+5n+−5

Combine Like Terms:

=−11+5n+−5

=(5n)+(−11+−5)

=5n+−16

Answer: 40%

Step-by-step explanation: to put it simply if you are using a calculator, enter 170÷425×100 which will give you 40 as the answer.

if you want an explanation here:

170 of 425 can be written as:

170/425.

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

170/425

×

100/100

(170 × 100/425) x 1/100

=

40/100

Therefore, the answer is 40%

Answer:

10x2+x

Step-by-step explanation:

Answer: x=5

Step-by-step explanation:

2x+22=4(x+3)

First distribute

2x+22=4x+12

Now intractable 2x from both sides

22=2x+12

Now subtract 12 from both sides

10=2x

Now divide by 2 to get x alone

5=x

So

x=5

Answer:

The answer is x = 5, see comments for explanation.

Answer:

Number of cars washed at the 6th hour = 12 cars

Sum of all cars washed in 6 hours = 42 cars

Step-by-step explanation:

First term, a = 2 cars

Common difference, d = 2 cars

6th term = a + 5d

= 2 + 5(2)

= 2 + 10

= 12 cars

Sum of the 6th term = n/2{2a + (n-1) d}

= 6/2{2*2 + (6-1)2}

= 3{4 + (5)2}

= 3{4 + 10}

=3(14)

= 42 cars

Answer:

Correct Answer: (8,2)

Step-by-step explanation:

Dilation about the origin

Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation.

In such cases, every point (x,y) dilated by a factor of k is mapped to the point (kx,ky).

The point R=(4,1) is dilated by a scale factor of 2 (k=2), thus the coordinates of its image are (2*4,2*1) = (8,2)

Answer:

40 1/2 days

Step-by-step explanation:

Quantity of biscuits the Jones eats daily = 2/3 of a packet

Total packets of biscuits = 27 packets

How long will 27 packets last the family?

= Total packets of biscuits / daily intake of biscuits of the Jones

= 27 ÷ 2/3

= 27 × 3/2

= 81 / 2

= 40 1/2 days

Answer:

Bike 1

Step-by-step explanation:

If you look at the graph, you'll see that Bike 1 went 9 feet but Bike 2 is at about 7.5 feet in 6 seconds.

Step-by-step explanation:

3x -1 +2x + 4 x +1 = 180

9x = 180

X= 20

<ABC = 59

< CB D = 40

Answer:

14.2%

Step-by-step explanation:

85+70= 155

155=100%

22=?

22×100%÷155

= 14.1935

hence answer is 14.2%

Step-by-step explanation:

Answer:

y=-2x-1

Step-by-step explanation:

Step-by-step explanation:

Case 1 : |x| > a, => x > a or x < -a

Case 2 : |x| < a, => -a < x < a

Since this question follows Case 1, we will have an "or" inequality.

Answer:

a) The height of the small object 3 seconds after being launched is 2304 feet.

b) The small object ascends 128 feet between 5 seconds and 7 seconds.

c) The object will take 6 and 10 seconds after launch to reach a height of 2640 feet.

d) The object will take 21 seconds to hit the ground.

Step-by-step explanation:

The correct formula for the height of the small object is:

[tex]h(t) = -16\cdot t^{2}+256\cdot t+1680[/tex] (1)

Where:

[tex]h[/tex] - Height above the ground, measured in feet.

[tex]t[/tex] - Time, measured in seconds.

a) The height of the small object at given time is found by evaluating the function:

[tex]h(3\,s)= -16\cdot (3\,s)^{2}+256\cdot (3\,s)+1680[/tex]

[tex]h(3\,s) = 2304\,ft[/tex]

The height of the small object 3 seconds after being launched is 2304 feet.

b) First, we evaluate the function at [tex]t = 5\,s[/tex] and [tex]t = 7\,s[/tex]:

[tex]h(5\,s)= -16\cdot (5\,s)^{2}+256\cdot (5\,s)+1680[/tex]

[tex]h(5\,s) = 2560\,s[/tex]

[tex]h(7\,s)= -16\cdot (7\,s)^{2}+256\cdot (7\,s)+1680[/tex]

[tex]h(7\,s) = 2688\,s[/tex]

We notice that the small object ascends in the given interval.

[tex]\Delta h = h(7\,s)-h(5\,s)[/tex]

[tex]\Delta h = 128\,ft[/tex]

The small object ascends 128 feet between 5 seconds and 7 seconds.

c) If we know that [tex]h = 2640\,ft[/tex], then (1) is reduced into this second-order polynomial:

[tex]-16\cdot t^{2}+256\cdot t-960=0[/tex] (2)

All roots of the resulting equation come from the Quadratic Formula:

[tex]t_{1} = 10\,s[/tex] and [tex]t_{2}= 6\,s[/tex]

The object will take 6 and 10 seconds after launch to reach a height of 2640 feet.

d) If we know that [tex]h = 0\,ft[/tex], then (1) is reduced into this second-order polynomial:

[tex]-16\cdot t^{2}+256\cdot t +1680 = 0[/tex] (3)

All roots of the resulting equation come from the Quadratic Formula:

[tex]t_{1} = 21\,s[/tex] and [tex]t_{2} = -5\,s[/tex]

Just the first root offers a solution that is physically reasonable.

The object will take 21 seconds to hit the ground.
