Answer:

y = 43, z = 16

Step-by-step explanation:

congruent essentially means they're the same. If you mentally map one triangle onto the other, you'll see that 43, the hypotenuse, lines up with y, and 16 lines up with z.

Answer:

9

Step-by-step explanation:

since they're similair then similair sides will be proportional

CB is similair to EF

[tex]\frac{6}{8}[/tex]= [tex]\frac{3}{4}[/tex]

same thing if you try with the hypotenuse AB similair to DE

[tex]\frac{13.5}{18}[/tex]= [tex]\frac{3}{4}[/tex]

So, if you multiply  r (DF) by 3/4  you will get the similair side AC

rx 3/4=12

r= 12÷ 3/4

r=16

Answer:

c)462m

Step-by-step explanation:

If a person walks round the park, the person would be walking the whole perimeter of the trail

Perimeter = 2 x (length + breadth)

2 x (30m + 47m) = 154m

If he walks three times, the distance covered = 154m x 3 = 462m

Answer:

B

The fountain F is located at the park's centroid and is 85 feet from entrance A.

Answer:

m<A = 39

Step-by-step explanation:

1. Approach

To solve this problem, one first has to find the value of "x", then one will substitute "x" back into the equation given for the value of m<A, to solve for m<A. In order to solve this problem, one has to know that the sum of angle measures in a triangle will always equal 180.

2. Solving for "x"

The sum of angle measure in a triangle will always equal 180 degrees, hence one can set up an equation,

m<A + m<B + m<C = 180

Substitute,

(10x - 1) + (18x + 2) + (15x + 7) = 180

Simplify,

43x + 8 = 180

Inverse operations,

43x + 8 = 180

        -8       -8

43x = 172

/43         /43

x = 4

3. Solve for m<A

Now all one has to do is substitute the value of "x" back in to solve for m<A

10x - 1

x = 4

10(4) - 1

40 - 1

[tex] \huge \boxed {slope = - 3}[/tex]

Step-by-step explanation:

[tex]m = \frac{rise}{run} [/tex]

The slope is the change of y over the change of x.

[tex]m = \frac{12 - 3}{ - 1 - 2} \\ m = \frac{9}{ - 3} \\ m = - \frac{9}{3} \\ m = - 3[/tex]

Therefore, the slope is -3.

Answer:

D: U= 2.5

Step-by-step explanation:

The value of u in the equation is approximately 2.5

where

(u – 2) = the number of hours sledding down the hill

The value of u can be found as follows:

9(u – 2) + 1.5u = 8.25

9u - 18 + 1.5u = 8.25

combine like terms

9u + 1.5u - 18 = 8.28

add 18 to both sides

10.5u = 8.28 + 18

10.5u = 26.28

divide both sides by 10.5

u = 26.28 / 10.5

u = 2.50285714286

u = 2.5

nth term =  2n^2

Step-by-step explanation:

The computation of the nth term of the quadratic sequence is as follows;

The given sequence is 2,8,18,32,50

Now

The first term, n = 1 = 2 × 1 × 1 = 2

Second term, n =2 = 2 × 2 × 2 = 8

Third, n =3  = 2 × 3 × 3 = 18

fourth term, n = 4,  = 2 × 4 × 4 = 32

fifth term, n =5,  = 2 × 5 × 5 = 50

Now finally  For nth term,  =  2  × n × n = 2n^2

Therefore nth term =  2n^2

16/15

[tex]1 \frac{1}{15} [/tex]

20/17

[tex]1 \frac{3}{17} [/tex]

Answer:

Step-by-step explanation:

1. When changing from improper fractions to mixed fractions, you have to divide the denomenator by the numerator and that is 7÷6 which should give you 1 remainder 1. Therefore ypur mixed fraction is 1 whole number 1/6.

2. 20/17 = 20 dividing 17 (20÷17)

Which is 1 whole number 3/17

3. Now the third too is 16/15 which is 16 dividing 15 (16÷15).

Therefore your answer is 1 whole number 1/15.

But in order to be sure of your answers, you will have to multiple the denomenator by the whole number plus the numerator.

Answer:

Each child ticket costs £2

Each adult ticket costs £5

Step-by-step explanation:

Let's define:

C = cost of a child ticket

A = cost of an adult ticket.

We know that:

"3 adult and 4 child tickets cost £23"

This can be written as:

3*A + 4*C = £23

"1 adult and 5 child tickets cost £15"

This can be written as:

1*A + 5*C = £15

Then we have the system of equations:

3*A + 4*C = £23

1*A + 5*C =  £15

To solve it, we start by isolating one of the variables in one of the equations:

Let's isolate A in the second equation:

A = £15 - 5*C

Now let's replace this in the first equation:

3*( £15 - 5*C) + 4*C = £23

Let's solve this for C

£45 - 15*C + 4*C = £23

£45 - 11*C =  £23

£45 - £23 = 11*C

£22 = 11*C

£22/11 = £2 = C

Each child ticket costs £2

And with the equation:

A = £15 - 5*C we can find the price of an adult ticket if we replace the value of C by £2

A = £15 - 5*£2 = £5

Each adult ticket costs £5

Answer: 66 weeks

Step-by-step explanation:

It will take approximately 3 weeks for the business to reach 75% awareness.

The compound annual growth rate (CAGR) is the annualized average rate of revenue growth between two given years, assuming growth takes place at an exponentially compounded rate.

here, we have,

To solve this problem, we can use the formula for compound growth:

E = B x (1 + R)^T

where E is the ending value (75% awareness in this case),

B is the beginning value (3% awareness),

R is the rate of growth (5%),

and T is the amount of time.

We can rearrange the formula to solve for T:

T = log(E/B) / log(1+R).

Plugging in the values from the problem, we get:

T = log(75/3) / log(1+5)

Calculating this out, we get:

T = 3.49 / 1.61

This simplifies to T = 2.16.

Since T represents the amount of time, we can round this up to 3 weeks. Therefore, it will take approximately 3 weeks for the business to reach 75% awareness.
