Answer:

the missing angle is easy. just remember the the sum of the 3 angles in a triangle is always 180°

then you calculate

180° - 90° - 35°

and get 55° for the last corner.

Answer:

x = 8

Step-by-step explanation:

m<PQR = (2x + 6)°

m<RPQ = (x - 7)°

m<QRS = (5x - 17)°

<PQR and <RPQ are interior angles opposite to the exterior angle <RPQ.

Therefore,

m<PQR + m<RPQ = m<QRS (Exterior Angle Theorem of a Triangle)

Substitute in the values

2x + 6 + x - 7 = 5x - 17

Add like terms

3x - 1 = 5x - 17

Collect like terms

3x - 5x = 1 - 17

-2x = -16

-2x/-2 = -16/-2

x = 8

(i) I used distributive property to get the x’s and y’s out of parentheses. I then combined like-terms to simplify until I could do no more. That is your final answer for (i) is -3x - 12y

(ii) This one is similar to the first one, just with no parentheses. I combined like terms again until not like terms were left. Your final answer for (ii) is -3k -2 -2n

(iii) I started by dividing 15 by 3 and got 5, and because the 15 had an x to it, you get 5x. I then moved onto the next term, 9. 9 divided by 3, to get 3. Your final answer for (iii) is 5x + 3

first chnge to improper or proper fraction

5*2/3

10/3

multiplicative inverse of 10/3 = 3/10

Answer:

(0, -6)

Step-by-step explanation:

Given the following systems of linear equations;

3x - 2y = 12 ...... equation 1

16x - 4y = 24 ........ equation 2

We would solve for the solution using the elimination method;

Multiplying eqn 1 by 2, we have;

2 * (3x - 2y = 12)

6x - 4y = 24

16x - 4y = 24

Subtracting the two equations, we have;

(6x - 16x) + (-4y -[-4y]) = (24 - 24)

-10x - 0 = 0

-10x = 0

x = -0/10 = 0

Next, we would find the value of y;

3x - 2y = 12

3(0) - 2y = 12

0 - 2y = 12

-2y = 12

y = -12/2

y = -6

Check:

3x - 2y = 12

3(0) - 2(-6) = 12

0 - (-12) = 12

12 = 12

A) Coefficient is the correct answer.

Step-by-step explanation:

The 3 is a coefficient. The x is the variable.

Answer:

8. cos(58) = 20/x

x · cos(58) = 20

x = 20/cos(58)

= 37.742

≈ 37.7

9. tan(69) = 324/x

x · tan(69) = 324

x = 324/tan(69)

FD=GD

9514 1404 393

Answer:

  19) ∠JKL ≅ ∠SLK

  20) FD ≅ GD

Step-by-step explanation:

It works well to identify the locations of the letters in the congruence statement, then use the letters in the same order from the other part of the congruence statement.

19) Letters JKL have the order 312 in the first part of the congruence statement ΔKLJ ≅ ....

The last part of the congruence statement is ... ≅ ΔLKS. The letters in order 312 from that part are SLK, so we want our angle congruence to read ...

  ∠JKL ≅ ∠SLK

__

20) The letters we're given (FD) are in positions 31 of the first part of the triangle congruence statement. The letters in those positions in the second part are GD, so our segment congruence is ...

  FD ≅ GD

The amount of money the store makes selling ice by the same ratio will be $340.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

The store sells 800 bags of ice, making $3,400.

Ratio = 3400/800

With the same ratio,

The store sells x amount of bags of ice,

x/80 = 3400/800

x = $340

Hence "The store will make $340 from selling ice using the same ratio".

You will purchase some cds and dvds. If you purchase 13 cds and 5 dvds, it will cost you $96.70; if you purchase 5 cds and 12 dvds, it will cost you $134.50. Write and solve a system of equations to solve for the cost of each cd and the cost of each dvd.

Cost of cd = $3.72

Cost of dvd = $9.66

Let the cost of a cd be c

Let the cost of a dvd be d

From the second statement:

If you purchase 13 cds and 5 dvds, it will cost you $96.70

This means that

13c + 5d = 96.70            ----------------(i)

Also, from the third statement:

if you purchase 5 cds and 12 dvds, it will cost you $134.50

This means that;

5c + 12d = 134.50            ---------------------(ii)

The equations to solve are equations (i) and (ii)

13c + 5d = 96.70

5c + 12d = 134.50

Multiply the first equation by 5 and the second equation by 13. i.e

5 x (13c + 5d = 96.70)

13 x (5c + 12d = 134.50)

This will give

65c + 25d = 483.5

65c + 156d = 1748.5

Find the difference of the two equations

    65c + 25d = 483.5

-

    65c + 156d = 1748.5

    0   -  131d   = - 1265

This gives;

-131d = -1265

Divide both sides by -131

[tex]\frac{-131d}{-131} = \frac{-1265}{-131}[/tex]

d = 9.66

This means that the cost of a dvd which is d = $9.66

Now substitute the value of d = 9.66 into equation (i) as follows;

13c + 5(9.66) = 96.70  

Expand the above and solve for c

13c + 48.3 = 96.70

13c = 48.4

c = [tex]\frac{48.4}{13}[/tex]

c = 3.72

This means that the cost of a cd which is c = $3.72

OPTION C is the correct answer.

Hope it helps you.

formula is Tn = 2n - 2

Answer:

z = 1.77.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X, which is also the area of the normal curve to the left of Z. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Find z such that 3.8% of the standard normal curve lies to the left of z

Thus, z with a z-score of 0.038. Looking at the z-table, this is z = 1.77.
