Answer:

1   1/4

Step-by-step explanation:

Just divide them, 3/4 divided by 3/5, then switch the fraction and sign.

Answer:

15/12

Step-by-step explanation:

3/4 divided by 3/5

That would become 3/4 times 5/3 because you take the reciprocal

3 x 5 = 15

4 x 3 = 12

So, 15/12 or 1.25

Given:

The point is (-5,7).

To find:

The image of the given point after 90 degrees counter clockwise rotation.

Solution:

If a point rotated 90 degrees counter clockwise, then

[tex](x,y)\to (-y,x)[/tex]

Let the given point is P(-5,7). Using the above rule, we get

[tex]P(-5,7)\to P'(-7,-5)[/tex]

Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).

Given:

Two trail maps:

Trail on the first map = 8 cm

Trail on the second map = 6 cm

Scale on first map = 1 cm : 2 km

A) What is the scale factor from the map to the actual trail?

For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.

The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm

B) The length of the actual trail is 16 kilometers.

Answer:

x < 3

Step-by-step explanation:

Isolate the variable, x. Treat the < sign as an equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, add 1 to both sides of the equation:

4x - 1 (+1) < 11 (+1)

4x < 11 + 1

4x < 12

Next, divide 4 from both sides of the equation:

(4x)/4 < (12)/4

x < 12/4

x < 3

x < 3 is your answer.

Step-by-step explanation:

for the given value x = -2

= 3(2x-4) + x^2 +5

= 3(-4 -4) +4+5

= -24+9

= -15

Answer:

5k

Step-by-step explanation:

The interest accrued on the principal is $100.

Using the formula;

A = P( 1 + r/n)^nt

A - amount

P - Principal

r = rate

n = Number of times the interest is compound

t = time in years

Substituting values;

A = 4,300( 1 + 0.023/365)365 × 1

A =  $4400

Interest =  $4400 - $4,300 = $100

The annual percentage yield is obtained from;

APY=100 (1 + r/n )n – 1

APY=100 (1 + 0.023/365)^n - 1

APY= 100(0.023)

APY= 2.3 %

Step-by-step explanation:Note:If this is wrong my apologies.Sorry if this doesn't help.

All i did to solve this math problem is that i factor k^2-2k-24 by using the AC method.

The factors of the quadratic equation by applying the factorization method are (k + 4) and (k - 6)

Used the concept of the quadratic equation which states that,

An algebraic equation with the second degree of the variable is called a Quadratic equation.

Given that,

The quadratic equation,

k² - 2k - 24

Now, apply the factorization method in the above equation,

k² - 2k - 24

k² - (6 - 4)k - 24

k² - 6k + 4k - 24

k (k - 6) + 4 (k - 6)

Therefore, the factors are,

(k + 4) (k - 6)

Answer:

Step-by-step explanation:

First calculate the total number of students in all the schools:

= 618 + 378 + 204  

= 1,200 students

Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.

North Middle school:  

= 618/1,200 * 20  

= 10 students

Central Middle School:  

= 378 / 1,200 * 20  

= 6 students

South Middle School:  

= 204/1,200 * 20  

= 4 students  

Answer:

Let AB be called x.

26/(18+x) = 14/x

14(18+x)=26x

252+14x=26x

252=12x

x=21

So, AB = 21

Step-by-step explanation:

Answer: In order to find what the coordinates of B are is by trying to know how we got to (-2,0) of line AB. You have to subtract 3 from A coordinate x which is 1,it will give you -2, and you have to subtract 1 from A coordinate y which is 1,it will give you 0.

Answer:

x = 14

BE = 6

Step-by-step explanation:

to find 'x':  BG = 1/2[(x-9) + (3x-13)]

BG = 4x-22 / 2

BG = 3x-25

3x-25 / 1 = 4x-22 / 2

cross-multiply:

4x-22 = 2(3x-25)

4x-22 = 6x-50

-2x = -28

x = 14

to find 'BE':  CB = BE

2x+4 = 7x-1

-5x = -5

x = 1

BE = 7(1) - 1

BE = 6
