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

Answer:

x = 7, y = 26

Step-by-step explanation:

y= 3x + 5

substitute into the second equation

2(3x + 5) = 4x + 24

6x + 10 = 4x + 24

2x = 14

x = 7

y= 3(7) +5

y = 26

The answer to the problem is -6.

The perimeter of the triangle is 70.82 inches.

Given as :

The length of the altitude is 30 inches, and

The length of the base is 10 inches

Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

Let, perpendicular = 30 and base = 5

According to Pythagoras theorem,

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

perpendicular² + base² = hypotenuse²

Substitute the values,

30² + 5² =  hypotenuse²

900 + 25 =  hypotenuse² or

hypotenuse² = 925

hypotenuse = √925

hypotenuse = 30.41

The perimeter of the triangle can be determined as:

Perimeter of the triangle = l₁ + l₂ + l₃

Perimeter of the triangle = 30.41+ 10 + 30.41

Perimeter of the triangle = 70.82

Hence, the perimeter of the triangle is 70.82 inches.

inside the triangle, the LMN is the equation 3x=90degrees

under the KN is 4x

on the left is 150dgrees = 5x

3x+4x+5x=360

add the x's together

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.

Trying again:

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.
