Answer:

Each batch of scones needed 0.67 kg of flour

Step-by-step explanation:

8.) It takes Fred 9 minutes to type and spell check 13 pages of a manuscript. Find how long it takes him to type and spell check
inysia [295]

It will take Fred 42 minutes to type and spell check 60 pages.

  • Let the first scenario be A.
  • Let the second scenario be B.
  • Let the unknown time be X.

Given the following data;

  • Time taken A = 9 minutes
  • Number of pages A = 13 pages
  • Number of pages B = 60 pages
  • Time taken B = X minutes

To find how long it takes him to type and spell check 60 pages;

We would use direct proportion to express the work described and solve for the unknown variable (time).

9 \;minutes : 13 \;pages\\\\X \;minutes : 60 \;pages

Cross-multiplying, we have;

9 × 60 = 13 × X

540 = 13X\\\\X = \frac{540}{13}

<em>X = 41.54 ≈ 42 minutes</em>

Therefore, it will take Fred 42 minutes to type and spell check 60 pages.

ZA<br> Round your answer to the nearest hundredth.
Ahat [919]

Answer:

<em>A = 48.81°</em>

Step-by-step explanation:

<u>Angles in a Right Triangle</u>

When the side lengths of a right triangle are known and an angle must be determined, we can use the trigonometric ratios that relate angles and sides.

The tangent ratio is defined as:

\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}

Opposite leg to angle A is 8 and adjacent leg is 7, thus:

\displaystyle \tan A=\frac{8}{7}

Using the inverse tangent funcion:

\displaystyle A=\arctan\frac{8}{7}

Calculating:

A = 48.81°
