Johanna is measuring the angles of a triangle. She measures the first two angles and gets 60° and 60°. What is the measure of the third angle? A) 30° Eliminate B) 60° C) 120° D) 300°

Since a triangle only has 180 degrees total, 60+60=120 degrees. So the third angle should be B. 60, because 180-120=60.

Which calculation should be completed first to solve this story problem? Allister bought some sheet music. He bought 6 songs for $0.99 each and 1 book for $16.99. He paid $1.38 in sales tax. He gave the cashier $50. How much change should Allister get? A. total cost of all the purchases B. total cost of 6 songs C. sum of the cost of 1 song, the book, and the tax D. the change

A. total cost of all the purchases

You can't calculate the sales tax on the sheet music or the change for $50 he would have received (which requires subtracting the total cost from $50) until you know how much the sheet music cost total.

 The B) and C) options aren't  relevant to the problem. You're trying to find the amount of change he gets after paying the total cost for all the sheet music + the tax on that.

Kedar is comparing the costs of phone plans. For phone plan A, the cost is $15.00 to connect and then $0.02 per minute. For phone plan B, the cost is $4.69 to connect and then $0.08 per minute. For what usage does plan A cost the same as plan B

Answer:  After 172 minutes (approx) the usage of plan A is same as the plan B.

Step-by-step explanation:

Here, For phone plan A, the cost is $15.00 to connect and then $0.02 per minute.

And, For phone plan B, the cost is $4.69 to connect and then $0.08 per minute.

Let after x minutes the total usage of plan A is same as plan B.

Therefore, 15.00 + 0.02 x = 4.69 + 0.08 x

15.00 = 4.69 + 0.08 x - 0.02 x

15.00 - 4.69 = 0.06 x

0.06 x = 10.31

x = \frac{10.31}{0.06}

x = 171.833333333\approx 172

Thus, after 172 minutes (approx) the usage of both plan will be same.

You usually buy a 16.5 -ounce bottle of shampoo. There is a new bottle that says it gives you 30% more free. What is the best equation

Answer:

The best equation is y= 16.5+0.3x

Step-by-step explanation:

Given : The bottle contain 16.5-ounce bottle of shampoo

A new bottle gives 30% more free in it

i.e. original+30% of original = new

16.5+0.3(16.5)= 21.45 amount of shampoo is in new bottle

so the best equation to define the answer is y= 16.5+0.3x

where x=16.5

Point D is the midpoint of the outer circle that we aim to find the area of

The circle has a diameter of WZ and radii of WC and CZ

We know that YZ=YD=10 cm

Let DC be x and CY be 10-x

The radius of the outer circle can be written as 8+8+x or 10+10-x which we can equate to find the value of x

8+8+x=10+10-x
16+x=20-x
2x=4
x=2

Therefore, the radius of the circle is 8+8+2=18

And hence the area of the circle is   \pi (18^{2})=324 \pi

The angle measures of quadrilateral RSTU are shown. m∠R = (2x)° m∠S = (3x – 35)° m∠T = (x + 35)° The measure of angle U is unknown. Can quadrilateral RSTU be a parallelogram?

Answer:

No, RSTU can not be a parallelogram.

Step-by-step explanation:

Given,

The angles measures of quadrilateral RSTU are,

m∠R = (2x)°

m∠S = (3x – 35)°

m∠T = (x + 35)°

Since, the sum of all interior angles of a quadrilateral is 360°.

m∠R +  m∠S +  m∠T +  m∠U = 360°

⇒ (2x)°  + (3x – 35)°  + (x + 35)° + m∠U = 360°

⇒ 6x + m∠U = 360°     ( By operating like terms )

m∠U = 360° - 6x      ( Subtracting 6x on both sides )

Now, we know that, the opposite angles of parallelogram are congruent or equal,

If RSTU is a parallelogram,

Then, m∠R =  m∠T and  m∠T = m∠U,

When, m∠R =  m∠T ⇒ (2x)° = (x + 35)° ⇒ x = 35°,

But, for x = 35°, 35+ 35 ≠ 360° - 6 × 35

m∠T ≠ m∠U

Hence, RSTU can not be a parallelogram.

A bowl contains 3 red, 8 blue, and 7 black beads. Margaret randomly selects 3 beads one after the other without replacement. Find the probability of getting a red, blue, and black bead, in that order. a. dependent; 204/7 b. independent; 7/243 c. independent; 1/68 d. dependent; 7/204

This is the concept of probability and statistics, we are required to calculate the probability of getting a red, blue and black respectively, given that there are 3 red, 8 blue and 7 black beads;
Probability of an event occurring=(Number of ways it can occur)/(Total number of outcomes )
The total number of outcome in our situation is:
3+8+7=18
P(Red)=3/18=1/6
P(Blue)=8/17
P(Black)=7/16
since these occurrence are such that the selection is without replacement, that means they are dependent. The probability of them occurring in that order will be:
P(x)=1/6*8/17*7/16=7/204
The answer is d. dependent; 7/204

△GHJ is mapped to △G′H′J′ using each of the given rules. For which rules is △GHJ congruent to △G′H′J′? a) (x, y)→(8x, 8y) b) (x, y)→(x+8, y−8) c) (x, y)→(−x, y) d) (x, y)→(0.8x, 0.8y) e) (x, y)→(−x, −y)

I'm not sure if this question is supposed to have a corresponding image. However, in dealing with congruence of an image to its pre-image, we simply need to determine whether the original image was resized or not.

Congruent images are images that are equal in measure. This will only result if the pre-image is a result of reflection, rotation, or translation.

(x, y)→(−x, y) ⇒ reflection

(x, y)→(−x, −y) 
⇒ rotation

(x, y)→(x+8, y−8) ⇒ translation
