Answer:

$h=\dfrac{2A}{b}$

Step-by-step explanation:

The formula for the area of a triangle is given by :

$A=\dfrac{1}{2}bh$

Where

b is base and h is height

We need to rearrange the formula to solve for height h.

Cross multiply the given relation

$2A=bh$

Dividing both sides by b.

$\dfrac{2A}{b}=\dfrac{bh}{b}\\\\h=\dfrac{2A}{b}$

So, the formula for the height of the triangle is $\dfrac{2A}{b}$ .

Which construction is being shown in the diagram?

11Alexandr11 [23.1K]

Answer:

Correct answer is option D) Construct the bisector of an angle.

Step-by-step explanation:

Angle bisector of an angle is a line that divides the angle in two equal parts.

A Line BD is called the angle bisector of $\angle ABC$ if

$\angle ABD = \angle CBD$

Please refer to image attached.

As per the question image, if the line PW is joined it will be the angle bisector of $\angle QPR$ .

Steps of construction of angle bisector:

1. Draw the angle QPR.

2. Open compass and make an arc that will cut the two lines on points Q and R respectively as shown in question figure.

3. With the same compass opening, put the compass on Q and make an arc in the area between $\angle QPR$ .

4. Draw an arc keeping the compass on R to cut the previous arc on point W.

Line joining the points P and W is the angle bisector of $\angle QPR$ .

So, Correct answer is option D) Construct the bisector of an angle.

The ratio of credit card sales to cash sales at a store was 8:3. If the store had 144 cash sales, how many more credit card sale

Neko [114]

Answer:

There were 240 more credit card sales than cash sales.

Step-by-step explanation:

By using the ratio 8:3 I was able to determine that if there were 144 cash sales that would mean that there would be 384 credit card sales. However, the question asks "How many more credit card sales were there than cash sales?" Meaning that we need to find the difference. 384-144= 240.

This means that there were 240 more credit card sales than cash sales.

Hope this helped! If you have any questions about what I did please comment!

Jessica drew a circle divided into 8 equal parts she shaded six of the parts what fraction is equivalent to the part of the circ

Anni [7]

Answer:

3/4

Step-by-step explanation:

Jessica shaded 6/8 of the circle. That fraction can be reduced by removing a factor of 2 from numerator and denominator. The reduced fraction is 3/4.

$\dfrac{6}{8}=\dfrac{2\cdot 3}{2\cdot 4}=\dfrac{2}{2}\cdot\dfrac{3}{4}=1\cdot\dfrac{3}{4}\\\\=\dfrac{3}{4}$
