Answer:

  (a) no

  (b) no

Step-by-step explanation:

The two questions are asking essentially the same thing. There is nothing that indicates DC ≅ DB or that AC ≅ AB. One (both) of these conditions is (are) required for ΔBAC to be isosceles, so that AD is both a perpendicular bisector of BC and a bisector of angle BAC.

There is not enough information to answer either question affirmatively.

Step-by-step explanation:

Front facing rectangle: lw=6*5=30

Back facing rectangle: lw=6*5=30

Top facing rectangle: lw=2*6=12

Bottom facing triangle: lw=10*6=60

Trapezoid: (h(a+b))/2=(3(2+10))/2=3(12)/2=36/2=18

Total surface area = 30+30+12+60+18=150ft²

Answer:

Near the mark at the bottom reading 100 mL

Step-by-step explanation:

We know that 1000 mL = 1 L

It means that 1 liter of a liquid contains 1000 milliliter of the liquid. In other words, in 1 liter there is 1000 mL of the liquid. And milliliter means one thousandth of a liter.  

So when we pour 97 mL of the water in a jar which has a capacity to fill water up to 1 L or 1000 mL, the water filling the jar will come close to the bottom of the jar which is approximately 100 mL .  It will rise up to the mark which reads 100 mL in the jar that is graduated.

Answer:

15,750 meters

Step-by-step explanation:

There are 1000 meters in a kilometer

.75 of a kilometer is 750 meters

There are 7 days in a week, 7x3 is 21.

750 x 21 = 15,750

Answer:

15750meters

Step-by-step explanation:

3 weeks=3x7

=21days

1day=0.75km

21days=21x 0.75

=15.75km

1km=1000m

15.75km=(1575/100 x 1000)m

=15750meters

45 boys, 27 girls

============================================================

Explanation:

g = number of girls

g+18 = number of boys, since there are 18 more boys than girls

For example, if g = 7, then g+18 = 7+18 = 25. In this example, we have 7 girls and 25 boys. The problem with this example is the ratio of boys to girls is 25:7 which is not equal to 5:3

We could use trial and error until we land on the solution, or we can use algebra as shown in the next section.

-------------------

The ratio of boys to girls is 5:3, meaning

(number of boys)/(number of girls) = 5/3

which turns into

(g+18)/g = 5/3

after we make the proper substitutions

Let's solve for g

(g+18)/g = 5/3

3(g+18) = 5g

3g+54 = 5g

54 = 5g-3g

54 = 2g

2g = 54

g = 54/2

g = 27

There are 27 girls.

This leads to,

g+18 = 27+18 = 45

So there are 45 boys

In total, we have 27+45 = 72 people

-----------------------------

Checking the answer:

The claim is that 45/27 is the same as 5/3

For now assume that claim is true. Set the fractions equal to each other and use cross multiplication like so

45/27 = 5/3

45*3 = 27*5

135 = 135

The third equation has the same thing on both sides, so it's a true equation. This must mean the first equation is true as well. Therefore, 45:27 and 5:3 are the same ratio and the answer is confirmed.

You could also use your calculator to note that

45/27 = 1.667

5/3 = 1.667

both decimal values are approximate.

The people there are in total of 72 students

Let the ratio of boys to girls be 5x: 3x

The ratio of boys to girls in a group is 5:3.

no. of boys = 18 + no. of girls

=> 5x = 18 + 3x

=> 5x - 3x = 18

=> 2x = 18

=> x = 18/2

x= 9

No. of boys = 5x

No. of boys= 5 × 9

No. of boys= 45

No. of girls = 3x

No. of girls= 3 × 9

No. of girls= 27

Total = 45 + 27

Total= 72

Hence, there are 72 students there.
