Answer:

The nth term is 3n+2.

The given sequence is in A.P.

Here,

First term,a= 5

Common difference,d= 3

Therefore the nth term = a+(n-1)d =5+(n-1)3

=5+3n-3 =3n+2.

Step-by-step explanation:

The number of 20 veggie burger, you bought.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

You buy a total of 50 turkey burgers and veggie burgers for $90.

You pay $2 per turkey burger and $1.50 per veggie burger.

Let x represents the turkey burger and y represents the veggie burger.

So, the system of equations,

x + y = 50   equation 1

2x + 1.5y = 90    equation 2

Substituting the value of x from the equation 1 to the equation 2,

100 - 2y + 1.5y = 90

y = 20

Then x = 30

Therefore, 20 veggie burgers you bought.

Answer:

1164

Step-by-step explanation:

Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.

384 + 600 + 192 = 1164

Answer:

Pretty Sure it’s 20mph

Step-by-step explanation:

X/20=x-10/30

30x=20x-200

30x=20x-200

-20x

10x=-200

Divied by ten on both sides.

x=-20

20mph

Answer: 1000(1.05)^X or C

Step-by-step explanation: F(x) = a(1+r)^X

A = Initial amount, which is 1000

r = growth rate, which is .05, and you add 1 to that

So it's 1000(1.05)^X

Answer:

4km/1.5km

Step-by-step explanation:

hope that helps :)

Ratio of 400m to 1.5km​ is 400/1500 or 400:1500

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Here the given quantities are 400m and 1.5km

The quantities are with different unit

We convert them into same unit

We know that one kilometre=1000 metre

One kilometre equal to thousand metres.

Let us convert 1.5 km to metre by multiplying 1.5 with 1000

1.5×1000=1500

The ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Hence  ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Step-by-step explanation:

length x or opposite will be 12.6

Answer:

x = 13

Step-by-step explanation:

Right Triangles

In a right triangle, there is an internal angle of 90°. The other two must add up to 90°.

The trigonometric ratios are satisfied in a right triangle. The tangent ratio, for example, is defined as:

[tex]\displaystyle \tan 35^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The angle of 35° is adjacent to the side of length 18 and is opposite to the side of length x, thus:

[tex]\displaystyle \tan 35^\circ=\frac{x}{18}[/tex]

Solving for x:

[tex]x=18\tan 35^\circ[/tex]

This is the equation to solve. Now substitute the tangent for its value to get

x = 13

Answer:

1. a = 21°

2. b = 70°

3. c = 89°

Step-by-step explanation:

1. Determination of the value of a.

a = 21° (vertically opposite angles are equal)

2. Determination of the value of b.

From the question given above,

110 + b = 180 (sum of angles on a straight line)

Collect like terms

b = 180 – 110

b = 70°

3. Determination of the value of c.

a + b + c = 180 (sum of angles in a triangle)

a = 21°

b = 70°

c =?

21 + 70 + c = 180

91 + c = 180

Collect like terms

c = 180 – 91

c = 89°

Answer:

Mia scored 6 baskets Last Saturday.

Step-by-step explanation:

Let:

Mia made score of baskets on Last Saturday = x

Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)

Total score of baskets = 24

We need to find How many baskets did Mia score last Saturday?

We can write:

Total Score = Score on Last Saturday + Score yesterday

[tex]24=x+3x[/tex]

Solving this equation we can find value of x:

[tex]24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6[/tex]

So, we get value of x = 6

Mia made score of baskets on Last Saturday = x = 6

Mia scored 6 baskets Last Saturday.

Answer:

2 [tex]\frac{1}{2}[/tex]pizzas

Step-by-step explanation:

The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.

To multiply 5/6 by 3, we can set it up as [tex]\frac{5}{6} * \frac{3}{1}[/tex]. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as [tex]\frac{1}{2}[/tex]. In total, they ate 2 [tex]\frac{1}{2}[/tex] pizzas.
