12 2/5 + (-3 1/4)

Answer:

3/10

Step-by-step explanation:

Answer: 3/10

Work (Easy Method): So the easy method is to count how many spaces are there, and since there are 10, you choose the 3/10

Work (Harder Method): You count the White spaces in both, and put it over the total spaces, So, since there's 4 white spaces in Tracy, and 10 total spaces, you do 4/10, and same goes with Carol. So, you just subtract 7/10 by 4/10, and you get 3/10

I hope this helps, and Happy Holidays! :)

Answer:

The value of f is 5

Step-by-step explanation:

Initially, the number of frog tadpoles = f

The initial probability of catching a frog tadpole = f/20

Adding 10 more frog tadpoles,

Number of frog Tadpoles = f +10

Total number of tadpoles in the pond = 20+10 = 30

new probability of catching a frog tadpole = (f+10)/30

New probability of catching a frog tadpole = 2 x Initial probability of catching a frog tadpole

(f+10)/30 = 2 x (f/20)

(f+10)/30 = f/10

f+10 = f x 30/10

f+10 = 3f

2f = 10

f = 5

Answer:

The arc length s = 44 inches

Step-by-step explanation:

We are given:

r = 4 in

Ф = 11 radians

We need to find s

The formula used is: [tex]s=r\theta[/tex]

where s represents arc length, r is radius and Ф is angle in radians

Putting values and finding s

[tex]s=r\theta[/tex]

Put r = 4 and Ф = 11

[tex]s=4\times 11\\s=44[/tex]

So, the arc length s = 44 inches

F(x) = -5x - 8, find F(6)

f(6) = -5(6) - 8

f(6) = -30 - 8

f(6) = -38

Answer: 1-7/8.

Step-by-step explanation;

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:  5/8 / 1/3 = 5/8 * 3/1.

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:  15/8.

15 ÷ 8 = 1R7, therefore:  1-7/8.

The required, 15/8, is the simplest form. It cannot be further reduced since the numerator (15) and the denominator (8) have no common factors other than 1.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. Let's calculate the division:

(5/8) ÷ (1/3)

Find the reciprocal of the second fraction:

Reciprocal of (1/3) = 3/1 = 3

Now, multiply the first fraction by the reciprocal of the second fraction:

(5/8) * 3 = (5 * 3) / 8 = 15 / 8

So, the answer to 5/8 divided by 1/3 in simplest form is 15/8.

Answer:

32

Step-by-step explanation:

x²+y² = 11 equation--(i)

2xy = 7 equation--(ii)

Here,

= x²+y²+6xy

= 11 + 6xy (x²+y² = 11 from equation--(i))

= 11 + 3 × 2xy

= 11 + 3 × 7 (2xy = 7 from equation --(ii))

y= 15

Step-by-step explanation:

The square shown on the left side of the problem is equivalent to 90 degrees.   Two 90 degree angles (complementary angle) equals to l80 degrees (a straight angle). Equation that is set up to solve for y: 6y= 90. 90 divided by 6 is 15.

Answer:

the answer is F

Step-by-step explanation:

The correct option is option F , that is figure F shows the rotational symmetry.

What is rotational symmetry ?

An object's ability to maintain the same shape when rotated about its own axis is known as rotational symmetry.

Some figures are given and we have to tell which figure doesn't illustrate rotational symmetry.

Let's check them all , one by one.

F)

We know that rotational symmetry meant a figure looks the same when it is rotated. Here , if we consider a point on the circle and try to rotate it about its own axis , then we get to know that the figure does not looks same in all directions.

So , this figure doesn't have rotational symmetry.

G)

This figure is when rotated about its own axis , we get that that it looks same in all directions. This figure has rotational symmetry.

H)

This figure also has rotational symmetry.

G)

We know that a triangle follows the rotational symmetry. If we rotate it , we get the same looks in all directions. This figure has the rotational symmetry.

Therefore , the correct option is option F , that is figure F shows the rotational symmetry.

Answer:

an = 4 · 2^(n - 1)

Step-by-step explanation:

Given:

an = a1 · r^(n - 1)

Where,

an = value of the n th term

a1 = value of the first term

r = common ratio

n = the term number.

What is the formula for the geometric sequence 4, 8, 16, 32, ...?

a1 = 4

r = 8/4

= 2

n = n(not given)

Substitute the values of a1 and r into the formula

a1 = 4

r = 2

an = a1 · r^(n - 1)

an = 4 * 2^(n - 1)

The correct answer is:

an = 4 · 2^(n - 1)
