How many 1 foot square tiles must be purchased to cover a 14 ft. by
11.5 ft. kitchen?

Step-by-step explanation:

2a-10=5(4+.2a)

Use the distributive property to multiply 5 by 4+0.2a..

2a-10=20+a

Subtract a from both sides.

2a-10-a=20

Combine 2a and -a to get a.

a-10=20

Add 10 to both sides.

a=20+10

Add 20 and 10 to get 30.

a=30

Answer:

number of dimes = 15

number of quarters = 2

Step-by-step explanation:

total money = $2 = 200 cents

types of coins are dimes and quarters

number of dimes are 13 more than quarters

let number of dimes be x and quarters be y

so our equation =

10x + 25y = 200

x = (y+13)

10(y+13) +25y= 200

10y + 130 +25y = 200

35y + 130 = 200

y = 70/35 = 2

cross checking :

x = y+13 = 15

amount = 10x15 + 25x2 = 150 + 50 = 200 cents = $2.

determine 3 ways to have 13 more dimes than quarters:

we can use linear equations and tables to solve.

Answer:

  74.8 m²

Step-by-step explanation:

The hint is usually a good place to start.

  A = (1/2)(11 m)(15 m)sin(115°) ≈ 74.8 m²

_____

Additional comment

As is often the case with over-specified triangle problems, the answer you get depends on how you work the problem. Here, the hint suggests you use the angle. If you use the three side lengths, you find the angle is 114.7° and the area is about 74.9 m².

Remark

The trick is to solve the inequality. The last step is very tricky. Be careful with it.

Equation

15≤ -3x + 6                     Subtract 6 from both sides

15-6 ≤ - 3x + 6 - 6            Combine

9 ≤  -3x                           Divide by - 3

9/-3 ≥ -3x/-3                   Notice what happened to the less than or equal to

-3  ≥ x

Now there are 2 problems remaining.

1) why did the inequality turn around?

It turned around because when you divide by a number less than 0, the inequality turns around because the negative numbers work opposite to the positive numbers .

18 > 6

-18 < - 6

2) So which graph is correct.

The largest number that is possible is -3 The arrowhead should be pointing left.

In addition, the circle should be blacked in.

The answer is as you have marked it: A

Answer:

(0, 19)

Step-by-step explanation:

Find the equation.

Find the slope:

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

22-16/1-(-1) = 6/2 = 3

Here's our equation so far:

y = 3x + b

Find b by plugging in one pair of (x,y) coordinates.

22 = 3(1) + b

22 = 3 + b

b = 19

Now we now the equation:

y = 3x + 19

So, the y-intercept is 19.

Use the Interest formula to find the rate:

Answer:

m<BHY = 90

m<RKH = 36

m<HBK = 54

Step-by-step explanation:

The diagonals in a kite are perpendicular, meaning that m<BHY has to be a right angle, and since KY bisects <RKB, <BKH≅<RKH which is 37. Because the angles in a triangle add up to 180, you can use subtraction to find out what the other missing angle, <HBK, is.

Answer:

d.   zeros: 2, 4           axis of symmetry: x = 3

Step-by-step explanation:

The zeros are the values of x where the graph crosses the x-axis

zeros = 2, 4

The axis of symmetry is the vertical line thru the vertex of the parabola

The vertex is (3, -1), so x = 3 is the axis of symmetry

Let's see

The visitor should run approximately 10.588 miles before swimming to minimize the time it takes to reach the island.

Here, we have,

To minimize the time it takes to reach the island, the visitor should run until the point where the time spent running is equal to the time spent swimming.

At this point, the total time taken to reach the island will be minimized.

Let's assume the distance the visitor runs is x miles.

Then the distance the visitor swims is (15 - x) miles.

Time spent running = Distance / Running rate

Time spent swimming = Distance / Swimming rate

Time spent running = x / 6

Time spent swimming = (15 - x) / 2.5

Now, we want to find the value of x that makes the time spent running equal to the time spent swimming:

x / 6 = (15 - x) / 2.5

To solve for x, cross-multiply:

2.5x = 6 * (15 - x)

2.5x = 90 - 6x

Add 6x to both sides:

2.5x + 6x = 90

8.5x = 90

Now, divide by 8.5:

x = 90 / 8.5

x ≈ 10.588

Now, the visitor should run approximately 10.588 miles before swimming to minimize the time it takes to reach the island.

Answer: Pipes

Step-by-step explanation: Pipes transfer water around and veins transfer blood around the body

Answer:

D. pipes

Step-by-step explanation:

Water isn't to lungs

water comes from a sink but it doesn't have the same relationship to the sink as blood does to veins

Water isn't to the ocean like blood:veins because the water is uncontrolled and is everywhere

that leaves water being to pipes like blood is to vessels and the image describes it better than I do

Answer:

option c is the correct answer

Answer:

C consecutive angle

Step-by-step explanation:

Answer:

1. BC = 25

2. m∠EDC = 125°

3) BD = 22

4) m∠EBD = 67°

5) FC = 17

6) m∠BEC = 24°

7) CD = 16

8) m∠DBC =  58°

Step-by-step explanation:

The dimensions of parallelogram EBCD are;

EB = 16, ED = 25, BF = 11, EC = 34, m∠BED = 55°, m∠CDB = 67°

1. BC = ED = 25 Opposite sides of a parallelogram are equal

2. m∠BCD = m∠BED = 55 opposite angles of a parallelogram are equal

m∠BCD + mEDC = 180° adjacent sides of a parallelogram are supplementary

m∠EDC = 180° - m∠BCD

∴ m∠EDC = 180° - 55° = 125°

m∠EDC = 125°

3) BD = BF × 2 Diagonals of a parallelogram bisect each other

∴ BD = 11 × 2 = 22

BD = 22

4) m∠EBD = m∠CDB = 67° from alternate angles between parallel lines

5) FC = EC/2 from diagonals of a parallelogram bisect each other

∴ FC = EC/2 = 34/2 = 17

FC = 17

6) m∠BEC = m∠BCE = 24° Alternate angles between parallel lines

m∠BEC = 24°

7) CD = EB = 16 Opposite sides of a parallelogram are equal

8) m∠EBC = m∠EDC = 125° from opposite angles of a parallelogram are equal

m∠DBC + m∠EBD = m∠EBC from angle addition postulate

∴ m∠DBC = m∠EBC - m∠EBD

m∠DBC = 125° - 67° = 58°

m∠DBC =  58°
