Step-by-step explanation:

Answer: k=3

Step-by-step explanation:

To solve for k, you want to isolate k.

[tex]\frac{2}{5} (5k+35)-8=12[/tex]            [add both sides by 8]

[tex]\frac{2}{5} (5k+35)=20[/tex]                  [multiply both sides by 5/2]

[tex]5k+35=50[/tex]                       [subtract both sides by 35]

[tex]5k=15[/tex]                               [divide both sides by 5]

[tex]k=3[/tex]

Now, we know that k=3.

Answer:

-3, -0.5, 1 3/4, 3

Step-by-step explanation: in a number line negative is always less than positive so the bigger the negative number the more is goes down on the number line so that's why -3 is smaller then -0.5 because -0.5 is closer to positive than -3

The value of fraction 0.5 7  is equal to 1/2.

We are given that;

Number = 0.57

Now,

There are different ways to express a fraction as a decimal, but one common method is to divide the numerator by the denominator.

For example, 1/2 as a decimal is 1 ÷ 2 = 0.512.

Another method is to use a fraction to decimal conversion chart or calculator345. According to these sources, 0.5 as a fraction is equal to 5/10 or 1/2.

These fractions are equivalent because they have the same value when simplified or reduced.

To simplify a fraction, we can divide both the numerator and the denominator by their greatest common factor (GCF).

Therefore, by algebra the answer will be 1/2.

Answer:  D(3) = 4 miles according to the graph.

Step-by-step explanation:

Look for the 3 on the time scale at the bottom of the graph. Follow the grid line straight up to where it meets the graphed line. Follow the grid line to the distance scale at the left to find the value at that point. It is 4 miles.

Answer:

-27

Step-by-step explanation:

First, let's call the smallest number: n

Then, the next two consecutive odd numbers would be:

n+2 and n+4 (this is because it's only odd numbers so we add 2)

We know the sum of these is −75 so we can write this equation and solve for n:

n + (n + 2) + (n + 4) = -75

n + n + 2 + n + 4 = -75

n + n + n + 2 + 4 = -75

n + n + n + 6 = -75

1n + 1n + 1n + 6 = -75

3n + 6 = -75        Subtract 6 from each side, which cancels the 6 on the left.

3n + 6 - 6 = -75 - 6

3n = -75 - 6

3n = -81       Divide each side by 3

3n/3 = -81/3

n = -81/3

n = -27

n + 2 = -27 + 2 = -25

n + 4 = -27 + 4 = -23

The 3 consecutive odd integers would be:

-27, -25, -23

Let's check our work:

-27 + -25 + -23 = -75    We are correct!

The smallest number is -27

Answer:

[tex]\boxed{x=10}[/tex]

Step-by-step explanation:

We are given two angles, which together, have a sum of 90°. We call these complementary angles. The angle ∠EAF is the complement of angle ∠FAB and vice versa.

Therefore, because they sum up to be 90°, we can simply add the angles together and solve for x this way.

[tex]4x+5x=90\\\\9x = 90\\\\\frac{9x}{9} = \frac{90}{9}\\\\\boxed{x = 10}[/tex]

The variable x equals 10. We can go even further to check and verify that this is correct by substituting our original value for x into the equation.

[tex]4(10)+5(10)=90\\\\40 + 50 = 90\\\\90 = 90[/tex]

90 does in fact equal 90, so your final answer is x = 10°.

Hope this helps! :)

Answer:

B (-5, 3)

Step-by-step explanation:

The line a passes through point ( 2,3 ).

Line b has equation y= -1

Plot the graph for line b, y=-1 , which is a horizontal line as shown in the attached graph

Plot point (2, 3) and draw the graph of line a, y=3 to form a line a parallel to line b

You will notice that point B (-5, 3) is the one the lies on line a.

The answer option A,(2,9) is incorrect  because it does not lie on any of the lines

The answer option C (0, 1) is incorrect because it lies along the y-axis

The answer option D (1, 4) is incorrect because it does not lie on any of the lines.

Answer:

See Below.

Step-by-step explanation:

Steps:

1) Draw the altitude of the triangle from Vertex B to side CA and label it h.

2) Find [tex]\sin(C)[/tex] of the triangle.*

3) [tex]\displaystyle \sin(C)=\frac{h}{a}[/tex]

4) Solve for h.

5) [tex]h=a\sin(C)[/tex]

6) Substitute expression for h into traditional formula for area of a triangle,[tex]\displaystyle A=\frac{1}{2}bh[/tex].

7) [tex]\displaystyle A=\frac{1}{2}ba\sin(C)=\frac{1}{2}ab\sin(C)[/tex]

(We acquire two right triangles after drawing h since it is an altitude. We will use the smaller of the two.)

b)

20 is 1000 times of 0.02. Correct answer is option C.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point.

Here, given value

0.02 = 002/100

        = 2/100

On multiply numerator and denominator by 10, we get

0.02 = 20/1000

or 20 = 1000 X 0.02

Thus, 20 is 1000 times of 0.02.

Answer:

A) 0

B) 0

C) 0

D) 0.5

Step-by-step explanation:

We are told that Men have XY (or YX) chromosomes and women have XX chromosomes

A) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;

{xX, YX, YX, xX}

The outcome for the son is;

{YX, YX}

The son will have the disease only if it's xY. Thus, probability of son having the disease is; 0/2 = 0

B) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;

{xX, YX, YX, xX}

The outcome for the daughter is;

{xX, xX}

The daughter will have the disease only if it's xx. Thus, probability of daughter having the disease is; 0/2 = 0

C) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;

{xX, xY, XX, XY}

Outcome for daughter is {xX, XX}

The daughter will have the disease it's xx. Thus, probability of daughter having the disease is; 0/2 = 0

D) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;

{xX, xY, XX, XY}

The male outcome is;

{XY, xY}

The son will have the disease only if it's xY. Thus, probability of son having the disease is; 1/2 = 0.5
