Triangle:
Area = 1/2*b*h
= (1/2)*3*4
= 3*2
= 6 m^2


7a.
1cm^3
Or, 1cm * 1cm * 1cm
Or, 10mm * 10 mm * 10 mm
Or, 1000 mm^3

7b.i)
10 cm^3
Or, 10cm * 1cm* 1cm
Or, 100mm * 10mm * 10mm
Or, 10000 mm^3

8.)
Volume = 50 cm^3
Base area= 5 cm^2
Now,
Volume = area * height
Or, 50 = 5 * height
Or, height = 50/5
Or, height = 10 cm

Plz mark this as the brainiest. :)

Help!!! Two customers took out car loans from a bank.
Nikitich [7]

Answer:

  • Susan paid $2220 more

Step-by-step explanation:

<u>Use the interest formula:</u>

  • I = Prt, where P - amount of loan, r- interest rate, t- time in years

<u>Robert:</u>

  • I = 30000*(4.9/100)*4 = 5880

<u>Susan:</u>

  • I = 30000*(4.5/100)*6 = 8100

<u>Difference in amounts of interest:</u>

  • 8100 - 5880 = 2220

Susan paid $2220 more

The following histogram presents the amounts of silver (in parts per million) found in a sample of rocks. One rectangle from the
gladu [14]

Answer:

  • <u><em>The height of the missing rectangle is 0.15</em></u>

Explanation:

The image attached has the mentioned <em>histogram</em>.

Such histogram presents the relative frequencies for the clases [0,1], [1,2],[2,3], [4,5], and [5,6] Silver in ppm.

Only the rectangle for the class [3,4] is missing.

The height of each rectangle is the relative frequency of the corresponding class.

The relative frequencies must add 1, because each relative frequency is calculated dividing the absolute class frequency by the total number in the sample; hence, the sum of all the relative frequencies is equal to the total absolute class frequencies divided by the same number, yielding 1.

In consequence, you can sum all the known relative frequencies and subtract from 1 to get the missing relative frequency, which is the height of the missing rectangle.

<u>1. Sum of the known relative frequencies</u>:

  • 0.2 + 0.3 + 0.15 + 0.1 + 0.1 = 0.85

<u>2. Missing frequency</u>:

  • 1 - 0.85 = 0.15

<u>3. Conclusion</u>:

  • The height of the missing rectangle is 0.15
