The Punnett square is a diagram divided into squares that is used to determine genotypes.

The question is incomplete, as the required details such as the characters that represent the plant heights and the flower colors are not given.

So, I will give a general explanation instead.

Assume the plants that are crossed are represented as: TT and Tt.

The possible genotypes would be TT, TT,Tt and Tt

In the above list of genotypes, genotype T is dominant over genotype t

Answer:

2,017

Step-by-step explanation: 2 meters= 2,000

So, 2,000+17= 2,017

2017 millimeters are in 2 meters, 17 millimeters as per the given unit conversion rate.

A statement of the connection between units that are used to alter the units of a measured quantity without affecting the value is called a conversion factor. A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).

Given, 1 meter is equal to 100 centimeters or 1,000 millimeters.

To calculate the total number of millimeters in 2 meters, 17 millimeters.

Since,

millimeters in 1 meter = 1000

Thus,

millimeters in 2 meter = 2000

millimeters in 2 meters, 17 millimeters = 2017

Therefore, there is 2017 mm in 2meteres, 17 mm as per the given unit conversion.

The total hours of work done by Laura is 39 hours.

A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:

Operands: Operands are the numbers that an operator uses. The terms that are given to the operands vary according to the kind of operation.

Given the hourly income Laura = $14.50

total hours she works in a week = 40

increase in rate after working after 10 hours is 1.5 times

the hourly rate after 10 hours = 14.50 x 1.5 = $21.75

amount earned in 10 hours = 10 x 14.5 = $145

total earning = $775.75

the amount left after reducing the amount of 10 hours = 775.75 - 145 = $630.75

$630.75 is earned in = 630.75/21.75 hours = 29 hours

total hours Laura worked = 10 + 29 = 39 hours.

Hence Laura worked 39 hours in a week.

[tex]\frac{17}4; -\frac{17}3[/tex]

Step-by-step explanation:

Option 1:  check the intersection of the curve with both axis by plugging x=0 (y axis) and y=0 (x axis). You will get

[tex]x=0 \implies 0-3y=17 \rightarrow y=-\frac{17}3\\y=0 \implies 4x-0=17 \rightarrow x=\frac{17}4[/tex]

Option2: (my favourite. Divide by 17 both sides to write the equation as [tex]\frac xp + \frac yq = 1[/tex]: p and q will give you the two intercepts:

[tex]4x-3y=17 \rightarrow \frac{4}{17}x - \frac3{17}y = 1 \rightarrow \frac{x}{\frac{17}4}+ \frac{y}{-\frac{17}3}=1[/tex]

Again, the two intercepts are [tex]\frac{17}4; -\frac{17}3[/tex]

Answer:

The x-intercept is ( 17/4, 0 ), The y-intercept is ( 0, -17/3 ).

Step-by-step explanation:

The y-intercept of a graph is the point of intersection between the y-axis and the graph. Since the y-axis is also the line x = 0,x = 0 in the equation. x-value of this point will always be 0.

x-intercept of a graph is the point of intersection between the x-axis and the graph. Since the x-axis is also the line y=0 y=0y, equals, 0, the y-value of this point will always be

0.

To find the y-intercept, let's substitute x=0 y:4⋅0−3y=17

-3y=17

y = -17/3

​So the y-intercept is (0, -17/3).

To find the x-intercept, let's substitute y = 0 into the equation and solve for x: 4x - (3⋅0) = 17

4x = 17

x = 17/4

So, the x-intercept is (17/4, 0).

In conclusion, The y-intercept is (0, -17/3).

The x-intercept is (17/4, 0).

Given,

Length of the rectangle = 5m 20cm = 5.2m

Breadth of the rectangle = 3.5m

Therefore,

Perimeter of the rectangle

= 2(Length + Breadth)

= 2(5.2m + 3.5m)

= 2 × 8.7m

= 17.4m

Hence,

Area of the given rectangle is 17.4 sq.m (Ans)
