Answer 1

Answer:

Answer:

∠ ABC = 75°

Step-by-step explanation:

using the sine ratio in right Δ ABD

sin ABD = $(opposite)/(hypotenuse)$ = $(AD)/(AB)$ = $(4)/(8)$ = $(1)/(2)$ , then

∠ ABD = $sin^(-1)$ ( $(1)/(2)$ ) = 30°

Using the sine ratio in right Δ CBD

sin CBD = $(opposite)/(hypotenuse)$ = $(CD)/(BC)$ = $(3)/(3√(2) )$ = $(1)/(√(2) )$ , then

∠ CBD = $sin^(-1)$ ( $(1)/(√(2) )$ ) = 45°

Then

∠ ABC = ∠ABD + ∠ CBD = 30° + 45° = 75°

If you divide an inheritance of $45,600.00 among 22 heirs, each heir will receive

Answers

It is simple
you do 45,600 divided by 22
which equals about 2,072.72

Each heir will receive 2072.72 inheritance.

We have to given that;

You divide an inheritance of $45,600.00 among 22 heirs.

And, To find each heir will receive inheritance.

Now, find each heir will receive inheritance as;

⇒ 45,600.00 divided by 22

⇒ 45,600 / 22

⇒ 2072.72

Thus, Each heir will receive 2072.72 inheritance.

The following graph represents a proportional relationship:A graph is shown. The values on the x axis are 0, 2, 4, 6, 8, and 10. The values on the y axis are 0, 6, 12, 18, 24, 30. Points are shown on ordered pairs 0, 0 and 2, 6 and 4, 12 and 6, 18 and 8, 27. These points are connected by a line. The label on the x axis is Bunches of Thyme. The title on the y axis is Price of Bunches.

True

False

Answers

If points (ordered pairs) connected by a line are:
(0,0), (2,6), (4,12), (6,18) and (8,24) [If you did not make a mistake by typing a point (8,27)], THEN
it is a direct proportional relationship in question, defined by formula:
y = k*x
where k is coefficient of this proportion, and x and y are coordinates of points respectively.
So, if you check for EACH point:
0 = k*0,
6 = k*2,
12=k*4,
18=k*6,
24=k*8,
for each of these equations, it is obtained for k to has value of 3.
And the rule is for a proportion, that has to have SAME k value for each of its points on a line.
So the answer is TRUE.
But if you did not make a mistake by typing point (8,27), then k value for its equation
27=k*8, will not be 3 as for the rest of the points.
And then, the answer would be FALSE, it is NOT a proportional relationship.

The variation of kernel color in corn plants is an inherited trait. R is the dominant allele for red kernels in a corn plant and r is the recessive allele for yellow kernels. What is the probability that a corn plant with the genotype Rr crossed with a corn plant rr will have offspring with the genotype rr? Express your answer as a fraction using numerals for numbers and / for the fraction bar.

Answers

The question ask to find the probability that a corn plant with the genotype Rr crossed with a corn plant rr and will have an offspring with the genotype rr. Base on the data, the possible probability would be 25% and base on the table or the cross breeding

Final answer:

The probability of having offspring with the genotype rr when a corn plant with the genotype Rr is crossed with a corn plant rr is 100%, or 1/1.

Explanation:

The probability of having offspring with the genotype rr when a corn plant with the genotype Rr is crossed with a corn plant rr can be determined using Punnett squares.

First, write the genotypes of the parents: Rr and rr.
Create a Punnett square by writing the alleles of one parent along the top and the alleles of the other parent along the side.
Fill in the boxes of the Punnett square with the possible combinations of alleles.
In this case, all the offspring will have the genotype rr, since r is the only allele from the second parent.

Therefore, the probability of having offspring with the genotype rr is 100%, or 1/1.
