Answer:

y = 1/3 x + 2

Step-by-step explanation:

We see points (-3, 1) and (3, 3).

We also see point (0, 2), the y-intercept.

To go from (-3, 1) to (3, 3), go up 2 and right 6.

slope = m = rise/run = 2/6 = 1/3

y = mx + b

y = 1/3 x + 2

Answer: 65 minutes

Step-by-step explanation: 26 / 4 = 6.5

6.5 tables per 10 minutes so 6.5 x 10 = 65 min

Answer:

1 hr and 5 minutes

Step-by-step explanation:

here's why... because 4 goes into 26 6 times with a remainder of 2 and there is 5 mins for every 2 tables and 6 times 10 is 60 which equals a hour and that will be a hour and 5 mins

Answer:

acute angle

Step-by-step explanation:

acute = angles that are less than 90⁰

The triangles which have three angles that measure less than 90° are:

acute triangle, equilateral triangle

"An acute triangle is a triangle with three acute angles that means each angle measures less than 90°."

"An equilateral triangle is a triangle where all sides and angles are equal. Each angle of an equilateral triangle measures 60°. "

"A right triangle is a triangle where one of the angle measures 90°. "

"A triangle that has two sides of equal length is called as an isosceles triangle. Also, two angles that are opposite to equal sides are always equal and measures less than 90°. "

For given question,

As one of the angle of right triangle measures 90°, it is not a required triangle.

Also, for isosceles triangle, although two equal angles measure less than 90°, the third angle can be 90°. So, an isosceles triangle is not a required triangle.

Therefore, the triangles that have three angles that measure less than 90° are:

1) acute triangle

2) equilateral triangle

The cost of cleaning each shirt is 3 dollars.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Assuming the cost of cleaning 1 shirt is x and the cost of cleaning 1 pant is y.

The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning.

∴ 5x + 3y = 30...(i)

The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning.

∴ 3x + 4y = 29...(ii)

Now to cancel out 'x' in both equations we multiply eqn(i) by 3 and eqn(ii) by 5.

So, 15x + 9y = 90...(iii) and 15x + 20y = 145...(iv)

Now subtracting (iii) from (iv) we get 11y = 55 ⇒ y = 5 and substituting the value of y in eqn(iv) we get x = 3.

Answer:

[tex]x = 70[/tex]

Step-by-step explanation:

Given

Molly: 50 out of 200

Joel: x out of 280

Required

Find x

Start by representing the giving parameters as ration

Molly= 50 : 200

Joel = x : 280

From the question, the ratios are equivalent. So,

[tex]50 : 200 = x : 280[/tex]

Convert to fractions

[tex]\frac{50}{200} = \frac{x}{280}[/tex]

Solve for x

[tex]x = \frac{50}{200} * 280[/tex]

[tex]x = \frac{1}{4} * 280[/tex]

[tex]x = \frac{280}{4}[/tex]

[tex]x = 70[/tex]

Answer:

8.5×10^-5

Step-by-step explanation:

Answer:

m∠X= 22°

Step-by-step explanation:

In ΔVWX:

m∠V=(7x−1) ∘

m∠W=(4x+16) ∘ ,

m∠X=(3x−17) ∘ . Find M∠X.

Step 1

We find the variable x

The sum of angles in a triangle is 180°

Hence,

ΔVWX = m∠V + m∠W +m∠X

180° = (7x - 1)° + (4x + 16)° + (3x - 17)°

180° = 7x - 1 + 4x + 16 + 3x - 17

180° = 7x + 4x + 3x - 1 + 16 - 17

180° = 14x -2

Collect like terms

180° + 2 = 14x

182° = 14x

x = 182°/14

x = 13°

Step 2

We find m∠X

m∠X = (3x−17) ∘

x = 13

m∠X = (3 × 13 − 17)°

m∠X = (39 − 17)°

m∠X = 22°

Step one:

given

the scale of the map

[tex]2 cm: 8 km.[/tex]

Step two:

so if a scale of 2 cm represents 8 km.

       then let xcm be 64km

cross multiply we have

[tex]x*8= 64*2[/tex]

8x= 128

divide both sides by 8

The map distance is 16cm

Answer:

A(n) = 4 + 8(n-1)

Step-by-step explanation:

A(n) = A(n-1) + 8

A(1) = 4

So A(2) = A(1) + 8 = 4 + 8

A(3) = A(2) + 8 = A(1) + 8 + 8 = 4 + 8 + 8

A(n) = 4 + 8(n-1)

The explicit formula for the arithmetic sequence with the given recursive formula A(n) = A(n-1) + 8 and the first term A(1) = 4 is A(n) = 8n - 4.

Given that the first term (A(1)) is 4, we can observe that each subsequent term is obtained by adding 8 to the previous term.

The general formula for an arithmetic sequence is A(n) = A(1) + (n-1)d, where A(n) represents the nth term, A(1) is the first term, n is the term number, and d is the common difference.

The first term (A(1)) is 4, and the common difference (d) is 8.

Plugging these values into the general formula, we have:

A(n) = 4 + (n-1)×8

A(n) = 4 + 8n - 8

A(n) = 8n - 4
