Answer:

Option D, All of the boys will have sweat glands

Step-by-step explanation:

Given -

Gene for sweat gland production is found on the X chromosome

Genotype of man - lacks sweat glands (XY)

Genotype of women - has normal sweat glands (X'X')

X' -  sweat glands

X - no sweat glands

This is an X linked recessive trait

If these two mates, then the all males will have sweat glands

X'X' * XY ---> X'X, X'X, X'Y, X'Y

Option D, All of the boys will have sweat glands

Answer:

Y=3x+2

Step-by-step explanation:

first you have to put it in the formula y = mx + c

Y=3-x

in this format c = 0 so there's no intercept

Y=3x+c

The parallel line will have the same gradient but different intercept.

Now we substitute the coordinates(1,5) into the formula.

y = 5

x = 1

5=(3*1)+c

5=3+c

Now we make c the subject.

c=2

So the answer is:Y=3x+2

Answer:

x=6.1

Step-by-step explanation:

using sine

sin 34 = opposite/hypotenuse

sin 34=3.4/x

make x subject of the formula

x =3.4/sin 34

x =6.08019161

x≈6.1(to the nearest tenth)

Answer:

b=2A/h

Step-by-step explanation:

[tex]A = \frac{1}{2} bh \\ \\ \therefore \: 2 A = bh \\ \\ \therefore \: b = \frac{2 A}{h} [/tex]

Answer:

b = 2A/h

Step-by-step explanation:

To isolate b, you should first "get rid" of the 1/2. The best way to do this to multiply both sides of the equation by 2. The left side becomes 2A, while the right becomes bh (1/2 multiplied by its reciprocal, 2, becomes 1). Next, you have to move the h to the left side, and you could do so by dividing both sides by h. The left side becomes 2A/h, and the right is just b by itself, getting you b = 2A/h.

Answer:

x = 90

Step-by-step explanation:

The three angles form a straight line so they add to 180

37+x+53 =180

90+x = 180

Subtract 90 from each side

90+x-90 =180-90

x = 90

Answer:

Total area of the two rooms   =   (width1length1) +   (width2length2)

Step-by-step explanation:

The area of the rectangular shape is given by = Length * breadth

Therefore the area of the two rooms can be calculated using the above formula when the variables lengths and widths are given.

Area 1= Area of the first room = length * breadth=  (width1length1)

Area 2=Area of the second room = length * breadth=  (width2length2)

Total area of the two rooms = Area1 + Area 2

                                         =   (width1length1) +   (width2length2)

Explanation:

Locate the point that has x = -3 as its x coordinate. The y coordinate is the output of the function when we use this x value. So the point (-3,-7) means that f(-3) = -7. As another example, f(2) = 3.

Answer:

  31.09

Step-by-step explanation:

You find the difference by subtraction:

  -31 -(-62.09) = -31 +62.09 = 62.09 -31

  = 31.09

-31 is 31.09 greater than -62.09.

Answer:

Deondra can buy 2 outfits.

Step-by-step explanation:

Since Deondra has $ 420 to spend at a bicycle store for some new gear and biking outfits, and she buys a new bicycle for $ 236.31, 2 bicycle reflectors for $ 3.07 each and a pair of bike gloves for $ 34.75, and she plans to spend some or all of the money she has left to buy new biking outfits for $ 59.50 each, to determine the number of outfits Deondra can purchase while staying within her budget the following calculation must be performed:

(420 - (236.31 + 2 x 3.07 + 34.75)) / 59.5 = X

(420 - (236.31 + 6.14 + 34.75)) / 59.5 = X

(420 - 277.2) / 59.5 = X

142.8 / 59.5 = X

2.4 = X

Therefore, Deondra can buy 2 outfits.

Answer:

43.5 in^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+b2) h  where b1 and b2 are the lengths of the bases and h is the height

We need to change 1 1/4 ft to inches = 1.25 (12) = 15 inches

A = 1/2 ( 15+14) 3

A = 1/2(29)*3

43.5 in^2

(3,4) and (6,2) could be vertices of a right triangle with (6,4) and (3,2)

(0,0) is on the same line as (6,4) and (3,2) so it doesn't even form a triangle, much less a right triangle.

(3,6) forms a scalene isosceles triangle, but not a right triangle  It's a 4-sqr13-sqr13 triangle

(4.5,3) also forms an obtuse isosceles triangle, but not a right triangle  It's a sqr13 - sqr3.25 - sqr3.25 triangle

Answer:

  140°

Step-by-step explanation:

Angles 1 and 3 are "corresponding" angles, so are congruent.

  ∠1 = ∠3

  20x +60 = 30x +20

  40 = 10x . . . . . . . . . . . . subtract 20x+20

  4 = x . . . . . . . . . . . . . . divide by 10

  ∠1 = 20x +60 = 20(4) +60 = 80 +60

  ∠1 = 140°

Answer:

140°

Step-by-step explanation:

Angle 1 and angle 3 are corresponding angles ;

Corresponding angles are equal ;

Hence,

Angle 1 = Angle 3

20x + 60 = 30x + 20

Collect like terms

20x - 30x = 20 - 60

-10x = - 40

x = 4

Angle 1 is thus :

20x + 60 ; x = 4

20(4) + 60

80 + 60

= 140°

Answer:

tough question guy needed more points to answer

Step-by-step explanation:

Answer:

a) The equation (10s + 8w) represents the calories Bridget ate on Monday and the equation (20s + w) represents the calories she ate the next day.

b) The number of calories in each strawberry is 4 and the number of calories in each vanilla wafer cookie is 19. The solution is s= 4 and w = 19.

Step-by-step explanation:

For part A, Bridget ate 10 strawberries and 8 vanilla wafer cookies on Monday. Since the the number of calories in a strawberry is s and the number of calories in a vanilla wafer cookie is w , the number of calories Bridget ate on Monday is 10s + 8w. The next day, Bridget ate 20 strawberries and 1 vanilla wafer cookie. Hence, the number of calories Bridget ate on the next day is 20s + w.

For part B,

we will create two different simultaneous equations.

Equation 1: 10s + 8w = 192

Equation 2: 20s + w = 99

We need to find one of the terms first to solve the other term. For this case, I will solve for w first.

Multiply the first equation by 2.

Equation 3: 20s + 16w = 192*2 = 384.

Now, subtract equation 2 from this new equation.

Equation 4:

(20s + 16w) - (20s + w) = 384 - 99

20s + 16w - 20s - w = 285

15w = 285

This leaves only w left and we can solve w.

w = 285 / 15 = 19

Now, we can solve for s using equation 2.

20s + 19 = 99

20s = 99-19 = 80

Hence,

s = 80/20 = 4
