Bob and John are 450 feet when they start running towards each other. Bob runs at a speed of 11 get per second, and John runs at a speed of 14 feet per second how too will they meet

Answer:

The correct selections are A and B.

Step-by-step explanation:

The picture depicted above can be represented as [tex]5w+4=99[/tex], since 5 times something plus 4 is the same as 99. In choice a, Andre babysat 5 times and earned the same amount of money each time, so you could represent that by [tex]5w[/tex]. Since he received an extra $4 and earned a total of 99 dollars, the first choice is correct. In choice B, the family of 5 paid the same amount for each ticket, which can be represented by [tex]5w[/tex]. Since they paid $4 for parking and paid a total of $99, choice B can also be represented by the picture, which means it's correct.

Answer:

[tex]141^{\circ}[/tex]

Step-by-step explanation:

The quadrilateral in the image is a cyclic quadrilateral, because it is circumscribed by a circle. In all cyclic quadrilaterals, each pair of opposite sides are supplementary (add up to 180 degrees). Therefore, we have the following equation:

[tex]m\angle T+39=180,\\m\angle T=\boxed{141^{\circ}}[/tex]

6x - 3

6(5) - 3 || replace the x with its value

30 - 3 || multiply (also known as simplify)

27 || subtract 3 from 30

Answer:

Step-by-step explanation:

10). m(arc AB) = m(arc BC) = m(arc CA)    [given in the picture]

     m(arc AB) = [tex]\frac{360^0}{3}[/tex]

                      = 120°

     Therefore, m(arc ACB) = m(arc AC) + m(arc BC)

                                            = 120° + 120°

                                            = 240°

11). m(arc CD) = 127°  [Given]

    m(arc AB) = 51° [Given]

    m(arc AC) = m(arc BD) [Given]

    m(arc CD) + m(arc BD) + m(arc AB) + m(arc AC) = 360°

    127° + 2[m(arc BD)] + 51° = 360°

    178° + 2[m(arc BD)] = 360°

    2[m(arc BD)] = 360° - 178°

    m(arc BD) = 91°

    Since, m(arc CDB) = m(arc CD) + m(arc BD)

    Therefore, m(arc CDB) = 127°+ 91°

                                           = 218°

12). m(arc EH) + m(arc ED) + m(arc DH) = 360°

     180° + 53° + m(arc DH) =360°

     m(arc DH) = 360° - 233°

    m(arc DH) = 127°

Answer:

The child has 6 dimes and 5 quarters.

Step-by-step explanation:

Let q and d represent the number of quarters and of dimes respectively.

Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).

Multiply the 2nd equation by 100 to remove the decimal fractions:

25q + 10d = 185 (Equation C)

Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:

-10q - 10d = -110

25q + 10d = 185  

--------------------------

15q = 75, and so q = 75/15 = 5.

According to Equation A, q + d = 11.  Replacing q with 5, we get:

5 + d = 11, and so d = 6.  

The child has 6 dimes and 5 quarters.

Answer: The amount of money in quarters is $1.75

Step-by-step explanation: There are 7 quarters. 25c+25c+25c+25c+25c+25c+25c=1.75

(–1, 5)

Step-by-step explanation:

(− 1  , ​5) is a solution of the system because it makes both equations true. The ordered pair, negative 1, 5, is a solution of the system because it makes both equations true.

after 5 weeks:  y = .25(5) + 4 which is 5.25 inches

after 12 weeks:  y = .25(12) + 4 which is 7 inches

Answer:

640 cm²

Step-by-step explanation:

The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths

Thus:

Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²

Area of Trapezoid ABCD = ? = x

Area of Trapezoid EFGH = 40 cm²

AB = 20 cm

EF = 5 cm

Substitute

x:40 = 20²:5²

x/40 = 400/25

x/40 = 16

Cross multiply

x = 16*40

x = 640

Area of trapezoid ABCD = 640 cm²

Answer:

7

Step-by-step explanation:

Expressing Both equations in the slope intercept format : y = mx + c

Function A :

y = 8x + 3

Where, slope = 8 ; intercept = 3

Function B:

y = x - 4

Note ;

Rate of change = slope

Rate of change or slope of function A = 8

Slope of function B = 1

Difference = 8 - 1 = 7

Answer:

111

Step-by-step explanation:

360 - 65 - 106 - 78 = 111

Answer: 3:1

Step-by-step explanation:

Let the cost of a game ticket be g.

Let the cost of a ride ticket be r.

The information given can be formed into an equation which will be:

3g + 4r = 39

Since Five ride tickets cost $15, the cost of each ride ticket will be:

= $15/5

= $3.

Therefore, 3g + 4r = 39

We put the value of r = $3 into the equation

3g + 4(3) = 39

3g + 12 = 39

3g = 39 - 12

3g = 27

g = 27/3

g = 9

The cost of a game ticket is $9

The ratio of the cost of a game ticket to the cost of a ride ticket will be:

= 9/3

= 3/1

= 3:1

The ratio is 3:1

Answer:

The longest length is 30 cm

Step-by-step explanation:

Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides

So, what we have to do here is divide the perimeter in the given ratio to get the side lengths

since 5 is the biggest of the numbers in the ratio, it represents the largest length value

so we have this as;

(3 + 4 + 5) = 12

So that would be;

5/12 * 72

= 5 * 6 = 30

Answer:

y=4.47 and x=√10

Step-by-step explanation:

180°-45°-90°=45°

√10/(sin 45°)=y/(sin 90)

y=4.47

√10/(sin 45°)=x/(sin45)

x=√10

Answer:

5/12 hours

Step-by-step explanation:

Honon = 3 1/4 hours

Sequoia = 2 5/6 hours

How much more time did Honon spend on homework than Sequoia

= number of hours Honon spent - number of hours Sequoia spent

= 3 1/4 hours - 2 5/6 hours

= 13/4 - 17/6

= (39-34) /12

= 5/12 hours

Answer:

130

Step-by-step explanation:

Answer:

6x² + 8x + 2

Step-by-step explanation:

(-x² + 2x - 3) + (7x² + 6x + 5 ) = ?

-x² + 2x - 3 + 7x² + 6x + 5 = ?

-x² + 7x² + 2x + 6x - 3 + 5 = ?

? = 6x² + 8x +2

Answer:

He can save $76.8 by buying them at the Fitness Depot.

Step-by-step explanation:

If the coach buys a dozen footballs, it means that he buys 12 and first, you need to determine the cost of purchasing the 12 footballs at each store by multiplying the amount of footballs for the price at each store.

-Sports R' Us: $27.99*12=$335.88

-Fitness Depot: $21.59*12=$259.08

Then, you have to find the difference between the total cost at both places:

$335.88-$259.08=$76.8

According to this, the answer is that he can save $76.8 by buying them at the Fitness Depot.
