a)45-(+15)+25-(-5)=?
b)-30-(-14)-(-4)=?​

Answer:

No, the given set of pairs does not represent a function

Step-by-step explanation:

For a set of values to be a function, each input must have one and only one output value

Now, for the given set, we can note that:

The input -13 has two output values; 4 and 9

Therefore, this set is not a function

Hope this helps :)

Answer:

Step-by-step explanation:

Perimeter of square park = 2000 m

4*side = 2000

   side = 2000 ÷ 4

  side = 500 m

Area of square park = side * side

                                 = 500 * 500

                                 = 250000 m²

Answer:

m∠ABC = 130°

Step-by-step explanation:

BD is the angle bisector of angle ABC .

Therefore, ∠ABD ≅ ∠DBC

Measure of angle DBC = 65°

Therefore, m∠ABD = m∠DBC = 65°

m∠ABC = m∠ABD + m∠DBC

              = 65° + 65°

              = 130°

Answer:

There are seven positions to be filled to form 7 letter words using the letters in the word PROBLEM.

Hope this helps!!!

There are 2 ways to arrange the letters in the word "PROBLEM" while keeping the consonants in their original order, using permutation.

The word "PROBLEM" has 7 letters

Number of  consonants = 5

Number of  vowels = 2

The problem can be solved using the rule of permutation.

The number of ways the vowels (O and E) can be arranged among themselves is given by the permutation of 2 objects taken all at a time, which is denoted as P(2, 2) or simply 2!.

P(2, 2) = 2! = 2 × 1 = 2

So, the vowels (O and E) can be arranged in 2 ways.

Therefore, the total number of ways the letters in the word "PROBLEM" can be arranged is 2 (the arrangements of vowels O and E).

Answer:

80 pieces of wire.

Step-by-step explanation:

It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.

Change 3 3/4 to a decimal

3.75

Change the 25 foot roll to inches.

25 feet * 12 inches / foot  = 300 inches.

Now how many pieces of wire do we get.

1 piece of wire/3.75 inches = x pieces of wire / 300 inches

3.75 * x = 300

3.75 * x / 3.75 = 300 / 3.75

x = 80

Step-by-step explanation:

The smaller triangle seems to have dilated and formed the larger triangle. So, let's find the factor of increase.

9 / 3 = 3, so 3 is the factor of increase.

Now we need to do 4 x 3 = 12

So, ? = 12

Answer: a) 6, 0, 10       b) yellow/orange line  

Step-by-step explanation:

a) Plug the x in the y functions, y = 2x² + x

when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6

when x = 0, y = 2(0)² + (0) = 0 + 0 = 0

when x = 2, y = 2(2)² + (2) = 8 + 2 = 10

b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.

And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.

Answer:

$0.24

Step-by-step explanation:

The computation of the price of the one pint of the mixture is shown below:

Since the ratio of apple juice and cranberry juice is 4:5

And, the price of apple juice is 45 cents i.e. = 0.45 × 4 ÷  9 = 0.2

Also the price of cranberry juice is $0.8 = $0.08 × 5 ÷ 9 = 0.04

SO, the price of one pint of the mixture is

= 0.2 + 0.04

= $0.24

Answer:

1249. 5 inches

Step-by-step explanation:

Pole length , Pl = 2 fts

Pole shadow, Ps = 20 in = (0.0833 * 20) = 1.666 ft

Tower length, Tl = 125 ft

Tower shadow, Ts = x

Pl / Ps = Tl/ Ts

2/ 1.666 = 125 / x

Cross multiply

2x = 125 * 1.666

2x = 208.25

x = 104.125 ft

x = 104.125 * 12 = 1249. 5 inches

Answer:

Measure of the arc = 14.32°

Step-by-step explanation:

Radius of a circle = 4 cm²

Area of the circle = πr²

Here, r = radius of the circle

Area of the circle = π(4)²

                             = 16π cm²

                             = 50.265 cm²

Since, area of a sector = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]

Here, θ = Central angle subtended by the arc Or measure of arc

Area of the sector given as 2 cm²

2 = [tex]\frac{\theta}{360}(50.265)[/tex]

θ = 14.32°

Therefore, measure of the arc = 14.32°.
