2. The number of nickels that Christine has is

Mathematics
1 answer:
aev [14]3 years ago
7 0

Answer:

The number of nickels is  15

The number of Dimes is 3

Step-by-step explanation:

Let the number of dimes  Christine has be d

The number of nickels with christine be n

Then the number of Nickels  Christine has will be  

n = 5d ----------------------------------(1)

Now The total value of both dimes and nickels is  = $1.05

This can be represented as

5n +10d = 105  (in cents)

From eq(1)

5(5d) + 10d = 105

25d+10d = 105

35d = 105

d = \frac{105}{35}

d = 3----------------------------------(2)

Substituting (2) in (1), we get

n = 5(3)

n = 15

What is 8.57 in fraction or mixed number as a decimal
aivan3 [116]
To write 8.57 as a fraction you have to write 8.57 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
8.57 = 8.57/1 = 85.7/10 = 857/100

And finally we have: 
8.57 as a fraction equals 857/100

Complete the identity. =( sin (alpha +beta))/ (cos alpha cos beta)=?
dem82 [27]
Hi, We know:

Sin(a + b) = 2.Sin(a).Sin(b)

Then,

= 2Sin(a).Cos(b)/Cos(a).Cos(b)

Canceling Cos(b)

= 2Sin(a)/Cos(a)

As Tan(a) = Sin(a)/Cos(a)

Then we will stay:

= 2Tan(a)

Or

= Tan(a) + Tan(a)

There is anything wrong on the alternatives

What is the value of y?<br><br><br><br> Enter your answer in the box.<br><br> y =
Olenka [21]

Answer:

y=40\°

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles  triangle

so

AB=AC

5x=40\°

x=8\°

The sum of the internal angles of a triangle is equal to 180\°

so

Find the value of y

(2y+20)\°+2(40\°)=180\°

2y=180\°-20\°-80\°

2y=80\°

y=40\°

Which figure could be the result of dilating this rectangle with a scale factor between 0 and 1? On a coordinate plane, a rectan
Leviafan [203]

9514 1404 393

Answer:

  (a)  On a coordinate plane, a rectangle has points (0, 0), (0, 1), (2, 0), (2, 1)

Step-by-step explanation:

Every point coordinate of the dilated figure will be smaller by the same factor.

Looking at the original (0, 3) coordinate, we find that possible answer choices include ...

  A (0, 1) has a scale factor of 1/3

  B (0, 4) has a scale factor greater than 1

  C (0, 1) has a scale factor of 1/3

  D (0, 2) has a scale factor of 2/3

__

Looking at the rest of the points in the answer selections, we find that the scale factors in choices C and D are not consistent from one point to another (or even within the same point). Those choices must be rejected.

In selection A, the image points are listed out of order, tending to confuse the issue. However, A is the correct choice.
