WHAT IS THE AMPLITUDE OF THIS FUNCTION

Answer: 31

Step-by-step explanation:

9 + 2 = 11. 11 is how old Kelly is in 2 years.

1/3 of 33 is 11. Kelly's mother is 33 in two years, meaning two years ago, Kelly's Mother is 31.

Here is the full equation.   K = Kelly.    M = Kellys Mom

9k = m

2k + 9k = m + 2m

11k = m + 2

11k = [tex]\frac{m}{3}[/tex]

M + 2 = 33

     -2    -2

m = 31

Answer:

74%

Step-by-step explanation:

How I did it is divided 37 and 50 (37/50 = 0.74)

1.y=16 x=8 ||| Because the 12 and 9 are the same side, i just decided to go from there, 9 is 75% of 12, so y and x would be

2.d=24 ||| the smaller triangle once again is 75% of the bigger one.

3.x=6 y=60 ||| the smaller triangle is 1/3 of the bigger one.

4. DE=8  AC=20 ||| The smaller triangle is half of the bigger one.

1. 6 is 75% of 8 and 12 is 75% of 16.

2. 18 is 75% of 24

3. 18/3=6 and 6 is 1/3 of 18; 20 is 1/3  of 60

4. 10 is 1/2 of 20; 1/2 of 16 is 8

Hope this helps.

Answer:

7 times 50=350

Step-by-step explanation:

Answer:

a₅₀ = 252

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 5 , then

a₅₀ = 7 + (49 × 5) = 7 + 245 = 252

Answer:

15 dimes, 12 quarters

Step-by-step explanation:

d + q = 27

.10d + .25q = 4.5

solve by substituting '27-q' for 'd'

.10(27-q) + .25q = 4.5

2.7 - .1q + .25q = 4.5

.15q = 1.8

q = 1.8/.15

q = 12

d = 27-12 which is 15

Answer:

c

Step-by-step explanation:

From the definition of a function, an x-value cannot have more than 1 corresponding y-value. Since x = -5 has already been used, it cannot be used again with a different value for y.

Step-by-step explanation:

Answer:

64 slices

Step-by-step explanation:

The first step to solving this is to find out how many slices of bread there were in total. We know that each loaf of bread had 16 slices, and we know that there were 8 loaves. To get the amount of slices, we multiply the amount of slices in each loaf by the number of loaves there are.

16⋅8=128 slices of bread in total

Now that we know the total number of slices, we need to find how many sandwiches they made. If they used two slices per sandwich, we would divided the total number of bread slices by two.

128÷2=64.

Answer:

125=12x+40

Step-by-step explanation:

Let the number of hours be x

And the total amount be =$125

We already have $40

Hence the expression is

125=12x+40

If we solve for x, the answer gotten is the number of hours

Answer:

34 °

Step-by-step explanation:

∠D = 71°

∠G = 37°

In ΔGEF

Using angle sum property of triangle : Sum of all angles of triangle is 180°

∠G+∠E+∠F = 180°

Since ΔGEF is right angled triangle at F so, ∠F = 90°

Now, 37°+∠E+90° = 180°

127°+∠E= 180°

∠E= 180°-127° =53°

Now ∠E+∠D = 53°+71°  = 124°

Now using exterior angle property in ΔABC

An exterior angle of a triangle is equal to the sum of the opposite interior angles

∠E+∠D is the exterior angle of  ΔABC

So, ∠A+∠B = ∠E+∠D

since  ΔABC is right angled triangle at B so, ∠B = 90°

∠A+90° = 124°

∠A = 124°-90°

∠A = 34°

Hence the measurement of angle A is 34 °

Assuming the following is a triangle, A = 72°

All interior angles of a triangle added together will always equal 180°, so [tex]180 - 71 - 37 = 72[/tex]

Step-by-step explanation:

These problems are about like terms.  Those are terms that are alike (same variables) but the coefficients (numbers in front) can be different.

1.  12m + 24m = 36m

2.  90a - 30a = 60a

Example:  6k + 8k + 10 = 14k + 10  (the part of the expression that's just a number does not combine with the parts that have variables).

3.  29b + 8

4.  36d + 25  (the terms with d in them combine--they don't have to be back-to-back)

5.  This is about the Distributive Property; first multiply 14 + 15f both by 3, then look for opportunities to combine like terms.

3(14 + 15f) + 79 = 42 + 45f + 79 = 121 + 45f

6.  20(18 + 5t) - 47 + 28t = 360 + 100t - 47 + 28t

    = 313 + 128t

Answer:

132 cm squared

Step-by-step explanation:

for the two triangles 8 times 3 divided by 2 is 12 times 2 for two triangles equals 24

the two side rectangles easy just do 5 times 6 and it equals 30 times two because there is 2 and you get 60

the bottom rectangle do the same thing except 6 times 8 and there is only one so 48

add all areas together to get 132

Answer:

4.71 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the above question,

r = QR = 3 units

θ = angle QRS= 90 = 90°

The length of the arc is calculated as:

2 × π × 3 × 90/360

= 4.7123889804 units

Approximately to the nearest hundredth = 4.71 units

Answer:

Lucy needs to invest $55,194.16

Step-by-step explanation:

Answer:

x = annual membership fee = $79

y = price per visit = $12

Step-by-step explanation:

Let

x = annual membership fee

y = price per visit

Brian:

x + 8y = 175

Samantha:

x + 13y = 235

x + 8y = 175 (1)

x + 13y = 235 (2)

Subtract (1) from (2) to eliminate x

13y - 8y = 235 - 175

5y = 60

y = 60/5

y = 12

Substitute y = 12 into (1)

x + 8y = 175 (1)

x + 8(12) = 175

x + 96 = 175

x = 175 - 96

x = 79

x = annual membership fee = $79

y = price per visit = $12

Answer:

140,120

Step-by-step explanation:

sum of angles in a quadrilateral =360

sum of the 1st two angles=60+40=100

360-100=260

the ratio of the remaining angles 7:6

therefore:

[tex] \frac{7}{13} \times 260[/tex]

=140

for the second angle

260-140=120

Answer:

a) x = 3

b) z = 10

c) p = 2

d) x = 7

e) u = 1

Step-by-step explanation:

a) 2x = 6

Despejamos x dividiendo por 2 a amabos lados de la eacuacion.

(2/2)x = 6/2

x = 3

Si remplazamos x en la ecuación original:

2(3)=6

6 = 6

Queda demostrado.

b) 10 + z = 20

Despejamos z restando 10 en amabos lados de la eacuacion.

10-10+z = 20-10

z = 10

Si remplazamos z en la ecuación original:

10 + 10=20

20 = 20

Queda demostrado.

c) p + 9 = 11

Despejamos p restando 9 en amabos lados de la eacuacion.

p + 9 - 9 = 11-9

p = 2

Si remplazamos p en la ecuación original:

2 + 9 = 11

11 = 11

Queda demostrado.

d) 3x + 8 = 29

Despejamos x restando 8 en amabos lados de la eacuacion y luego divideindo por 3 en ambos lados de la ecuación.

3x+8-8 = 29-8

3x = 21

(3/3)x = 21/3

x = 7

Si remplazamos x en la ecuación original:

3(7) + 8 = 29

21 + 8 = 29

29 = 29

Queda demostrado

e) 2u + 8 = 10

Despejamos u restando 8 en amabos lados de la eacuacion y luego divideindo por 2 en ambos lados de la ecuación.

2u+8-8 = 10-8

2x = 2

(2/2)x = 2/2

x = 1

Si remplazamos x en la ecuación original:

2(1) + 8 = 10

2 + 8 = 10

10 = 10

Queda demostrado

Espero te haya sido de ayuda!
