Answer:

2/3, 1, and 6/5

Step-by-step explanation:

This is all just a matter of substitution. The values given of x = 1, x = 4/9 and x = 1 1/3 just need to be substituted in as x itself.

If x = 1, then the expression will be as the following: 4/15÷1+0.4. Dividing anything by 1 is just the same number, so 4/15 remains the same. 0.4 as a fraction is 4/10. A common denominator is 30, as both 10 and 15 fit into 30, so:

8/30+12/30=20/30, which can be simplified into 2/3

If x = 4/9, then we just substitute again. 4/15÷4/9+0.4. Due to BIDMAS, we do 4/15÷4/9 first, and to divide fractions, we use the KCF rule of Keep, Flip, and Change. We Keep the first fraction (4/15), Change the division sign into multiplication and then Flip the second fraction so it becomes 9/4

Now, we multiply the two fractions (4/15×9/4) to get 3/5, and then adding 4/10 to that gives us just 1.

If x = 1 1/3, we do the exact same thing we did for x = 4/9 to get 6/5. Good luck.

Answer:

x = 114°

y = 27

Step-by-step explanation:

To get x, we simply subtract 66° from 180°. Because of same-side interior angles, the angle below x is 66°.

To find y, we set the expression equal to 66° because they are the same angle. When we solve for y, we get 27.

Answer:

x= 114,

y= 27

Step-by-step explanation:

x= 180 - 66 = 114

6y - 96 = 66, 6y= 66+96, 6y= 162, y= 162/6, y= 27

Answer:

D

Step-by-step explanation:

[tex]P(1+r\%)^t[/tex]

[tex]700 \times (1+0.8\%)^5[/tex]

[tex]700 \times (1+0.8/100)^5[/tex]

[tex]700 \times (1+0.008)^5[/tex]

[tex]700 \times (1.008)^5[/tex]

The value expresses the population five years later is (700)(1.008)^5.

We have given that in 1997 the population of a small town was 700.

The annual rate of increase is about 0.8%.

We have to find the population for 5 years

[tex]F=P(1+r)^t\\\\[/tex]

Here p=700

r=0.8/100=0.008

t=5

Use the above value in the formula so we get,

[tex]F=700(1+0.008)^5[/tex]

[tex]F=700(1.008)^5[/tex]

Therefore option D is correct.

Answer:

x + 2y = -1

Step-by-step explanation:

First, we'll find the slope.

Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2

Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:

y - 2 = -1/2(x - (-5))      *I used (-5, 2) but it doesn't matter which point you use

y = -1/2(x + 5) + 2

y = -1/2x - 1/2

Standard form:

1/2x + y = -1/2

x + 2y = -1

Answer:

the solution is (-2, 1)

Step-by-step explanation:

In the first equation, substitute -2 for x.  We get:

y = -2 + 3 = 1

So the solution is (-2, 1)

The solution of system of Equations is x= -2 and y= 1.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the Equation:

y= x+ 3

x= -2.

So, putting the values in equation in (1) we get

y = -2 + 3

y = 1.

Thus, the solution is x= -2 and y= 1.

This is really weird. None of them seem to be right.

For the first one, it says that -7.5 is greater than or equal to -6.4, which is not true. -7.5 is less than -6.4. The next one is the only one that makes a true comparison, but I don't agree with the "or equal to" part. -7/8 cannot be equal to 7/8. The next one is false, -4 is greater than -8. Finally, the last one is incorrect as well because -4.2 is less than -3.6.

Answer:

  True

Step-by-step explanation:

The measure of the angle where secants intersect outside the circle is half the difference of the measures of the intercepted arcs. A pair of tangents is a special case where the intercepted arcs meet each other. The same relation regarding arc and angle measures still applies.

The given statement is true.

The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Now, The diagram is attached below

AB  and BC are the two tangents

By exterior angle theorem

∠3 = ∠2 + ∠4

So   ∠2 = ∠3 - ∠4

Now we find angle 3  and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc

∠3 = 1/2 arc ADC

∠4 = 1/2 arc AC

∠2 = ∠3 - ∠4

∠2 = 1/2 arc ADC - 1/2 arc AC

∠2 = 1/2 ( arc ADC - arc AC)

Thus, The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.

Answer:

The answer is 166/21, or 7 19/21

Step-by-step explanation:

First, you would set up the equation, which is:

13 1/7 - 5 5/21

Next, you would turn them into an improper fraction, which is:

92/7 - 110/21

Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:

276/21 - 110/21

Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.

Answer:

7 19/21

Step-by-step explanation:

13 1/7 - 5 5/21

Get a common denominator

13 1/7*3/3 - 5 5/21

13 3/21 - 5 5/21

We need to borrow 1 from the 13 in the form of 21/21

Answer:

Number of ounces of iodine 888 brand = 68

Number of ounces of iodine 232 brand = 325

Step-by-step explanation:

Given the following ;

Brand 232:

Cost per ounce = 36cent

Brand 880:

Cost per ounce = $2.04 = 204cent

Assume the following :

Number of ounces of 232 brand = x

Number of ounces of 888 brand = y

Total ounces to be made :

x + y = 393 - - - (1)

Total cost of iodine :

Brand 232 = 36x

Brand 888 = 204y

36x + 204y = 25572 - - - - (2)

From (1)

x = 393 - y - - - - (3)

Substitute (3) into (2)

36(393 - y) + 204y = 25572

14148 - 36y + 204y = 25572

-36y + 204y = 25572 - 14148

168y = 11424

y = 11424 / 168

y = 68

From ; x = 393 - y

y = 68

x = 393 - 68

x = 325

Number of ounces of iodine 888 brand = 68

Number of ounces of iodine 232 brand = 325
