# 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°

QUESTION POSTED AT 09/10/2019 - 11:04 PM

QUESTION POSTED AT 09/10/2019 - 11:04 PM

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

12 yards, 432 inches and 36 feet are all equal

12 yards = 36 feet

36 feet = 432 inches

12 yards = 36 feet

36 feet = 432 inches

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.

**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,

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

Well, we can clearly see that both axises are labeled. The left axis (often called the y-axis) is labeled **Scores** and the bottom axis (often called the x-axis) is labeled **Students**.

The graph doesn't look to be misleading either.

**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

QUESTION POSTED AT 17/10/2019 - 09:01 AM

**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.**

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

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
