1) Madison went shopping and spent $125 she paid $45 in Texas what was the sale tax rate (percent)
Gnesinka [82]

Answer:

170

Step-by-step explanation:

<em>How the sales tax de-calculator works </em>

<em>Step 1: take the total price and divide it by one plus the tax rate. </em>

<em>Step 2: multiply the result from step one by the tax rate to get the dollars of tax. </em>

<em>Step 3: subtract the dollars of tax from step 2 from the total price. </em>

<em>Pre-Tax Price = TP – [(TP / (1 + r) x r] </em>

<em>TP = Total Price.</em>

Looking for right triangle side a is 1 inch long,and side b is 2 inches long. What is the length of side c?
Sergeeva-Olga [200]

Answer:

\sqrt{5}

Step-by-step explanation:

a^{2} + b^{2} = c^{2}

In this situation a = 1, b = 2

1^{2} + 2^{2}  = c^{2}

1 + 4 = c^{2}

5 = c^{2}

c = \sqrt{5}

This is an important mathematical theorem to know. It's called the Pythagorean Theorem.

John wants to measure the width of a stream using the methods he has learned in geometry. He puts a stake in the ground opposite
otez555 [7]

John's method to determine the width of the stream uses the knowledge

that the tangent of 60° is approximately 1.7.

The proper sequence John would use to find the width of the stream are;

  • Step 1; <u>John</u><u> drives a stake opposite the tree to establish a line between two points</u>

  • Step 2; <u>John uses a </u><u>compass </u><u>to walk away from the stakes at a right angle</u>

  • Step 3; <u>On the path John walks until he finds a </u><u>line </u><u>of sight to the tree that equals 60 degrees</u>

  • Step 4; <u>John drives a second </u><u>stake </u><u>in the ground</u>

  • Step 5; <u>John measures the the </u><u>distance </u><u>between the two stakes</u>

  • Step 6; <u>John </u><u>multiplies </u><u>the distance between the two stakes by</u><u> 1.7</u><u> to find the distance</u>.

Reasons:

The steps that can be used to measure the width of the stream are;

Step 1: Drive a stake opposite the tree on the other side of the stream.

Step 2: With the aid of a compass, walk at right angles to the line formed by the stake and the tree.

Step 3; Keep walking along the previous path till a point is reached where the angle formed between the line of site to the tree and the walk path is 60°.

Step 4; At the point where the line of sight to the tree is 60°, a second stake is driven in the ground.

Step 5; Measure the distance between the stakes that are placed in the ground.

Step 6; Given that by trigonometry, the ratio of the width of the stream to the distance between the two stakes is tan(60°) ≈ 1.7, multiply the distance between the two stakes by 1.7 to find the width of the stream.

\displaystyle tan(60^{\circ}) = \mathbf{\frac{Width \ of \ stream}{Distance \ between \ stakes}}

<em>The possible question options are;</em>

<em>John measures the the distance between the two stakes</em>

<em>John uses a compass to walk away from the stakes at a right angle</em>

<em>John multiplies the distance between the two stakes by 1.7 to find the distance</em>

<em>John drives a second stake in the ground</em>

<em>On the path John walks until he finds a line of sight to the tree that equals 60 degrees </em>

<em>John drives a stake opposite the tree to establish a line between two points.</em>
