A scale model of a street sign is in the shape of a triangle. The base is 4.25 cm and the height is 8.8 cm what is the area of t
agasfer [191]

Answer:

18.7 cm²

Step-by-step explanation:

To work out the area of a triangle you have to use the formula

\frac{1}{2} * B * H

Where "B" is the base and "H" is the height

Since these are decimals, I like to convert them into fractions which makes them easier to calculate with

The base is 4.25 cm which will turn into 4\frac{1}{4}

The height is 8.8 cm which will turn into 8\frac{8}{10}

Now we use the formula

 \frac{1}{2} * B * H

 \frac{1}{2} * 4\frac{1}{4} *8\frac{8}{10}

→ Convert to improper fractions

 \frac{1}{2} * \frac{17}{4} *\frac{88}{10}

→ Simplify

 \frac{187}{10}

→ Convert into decimal

18.7

Ben wants to get a 94 in math class. His grade will be the average of two test scores. He scored an 89 on the first test. What g
In-s [12.5K]

Answer:

Ben needs to get a 99% on his second test

Step-by-step explanation:

The average is the sum of both test scores, divided by the total number of test scores (2).

Let x by the grade Ben must receive on his second test.

(89 + x)/2 = 94

Multiply by 2 on both sides

89 + x = 188

Subtract 89 on both sides

x = 99

Check work:

(89 + 99)/2 = 188/2 = 99

Estimate the perimeter of the figure to the nearest whole number.
Brrunno [24]

Answer:

<u>The perimeter of the pentagon ≅ 19 units (approximately)</u>

Step-by-step explanation:

Clockwise, starting from the base of the pentagon, we have:

  • Base of the pentagon or bottom side ≅ 4 units
  • 2nd side ≅ 3.75 units
  • 3rd side ≅ 3.75 units
  • 4th side ≅ 3.75 units
  • 5th side ≅ 3.75 units

In consequence,

Perimeter of the pentagon ≅ 4 + 3.75 + 3.75 + 3.75 + 3.75

<u>Perimeter of the pentagon ≅ 19 units</u>
