3.5325

Step-by-step explanation:

find the area and divide it by 2

1.5*1.5*pi= 1.5*1.5*3.14= 7.065

then divide it by two= 3.5325

Answer:

3/7 is the probability that the teacher will randomly select a boy.

Hope this helps! :)

The probability that the teacher randomly selects a boy is 3/7

The given parameters are:

Boy = 6

Girls = 8

The total number of students is:

Total = 6 + 8 = 14

The probability of selecting a boy is:

P(Boy) = 6/14

Simplify

P(Boy) = 3/7

Hence, the probability that the teacher randomly selects a boy is 3/7

Answer:

z=130°

Step-by-step explanation:

These are supplementary angles so

z=180-50=130°

Answer:

130

Step-by-step explanation:

That is a straight angle. It has 180 degrees, correct? So you'd have to subtract 180-50 to get your answer of 130.

The solution is, when Mendel cross-pollinated true-breeding purple flowering plants and true-breeding white flowering plants, purple flowers are obtained.

Blended inheritance is a form of inheritance which combines characteristics from both parents. It occurs when the genetic contribution from each parent is not distinct, and instead, the traits of both parents are combined in the offspring. It is also known as "mosaic inheritance" or "mixed inheritance". It can occur in both plants and animals. Blended inheritance is different from Mendelian inheritance, which involves the segregation of individual traits from each parent.

here, we have,

This result showed that the traits for flower color were inherited in a non-blended manner, with one dominant trait (purple flower color) masking the recessive trait (white flower color).This experiment contradicts the idea of blended inheritance, which states that the traits of offspring are a blend of the traits of the parents. Mendel’s experiments showed that traits were passed on in a discrete and non-blended manner, with the dominant trait being fully expressed in the offspring and the recessive trait not being expressed at all.

Therefore, purple flowers are obtained when Mendel cross-pollinated.

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Step-by-step explanation:

y= 3x + 5

6x + 10 = 4x + 24

2x = 14

x = 7

y= 3(7) +5

y = 26

1/3 of 80= 26.7(1dp)

1/4 of 80= 20

26.7+20= 46.7(1dp)

80-46.7= 33.3(1dp)

Either 33 or 34 people

Answer:

30

Step-by-step explanation:

We can estimate that 1/4 people had cereal and after that, half chose eggs/ meat over toast/roll.

1/4 * 80 is 20 So we are left with 60.

60/2  is 30.

So I would estimate 30 people chose eggs and meat.

Answer:

if pi is 3.14: 163.52 [tex]m^2[/tex]

if pi is just π: 264 - 32π [tex]m^2[/tex]

Step-by-step explanation:

22 x 12 = 264

4 x 4 = 16

16 x 2 = 32

16 x 3.14 = 50.24

264 - 50.24 x 2 = 163.52

Answer:

163.47

Step-by-step explanation:

We know the area of the whole rectangle by multiplying 12 by 22 to get 264. Now we just have to find the area of the circles and subtract it from the rectangle.

The area of a circle is πr^2. These circles' radii is 4, so 4^2π = 16π

Since there are 2 circles, double 16π to get 32π, 32π is equal to 100.53096491, rounded to 100.531. 264 - 100.531 = 163.469, rounded to 163.47

8x (the babysitter gets paid 8 dollars an hour, and x represents number of hours)

3 (this is the additional tip the babysitter gets; it's not dependent on the number of hours she/he works)

The babysitter will get paid the same despite babysitting two kids- no variable here is dependent on the amount of kids the babysitter babysits.

Answer:

A) 8x + 3

Step-by-step explanation:

The babysitter gets 8 dollars per hours, and x is the hours, so 8x, 8 dollars per hour. She also gets 3 dollars if she gets the children to sleep on time, so add 3. The equation is 8x + 3.
