All you have to do is multiply 5 * 5 = 25 and then add 4, 25 + 4 = 29. So, your answer would be 29/5

Gre4nikov [31]

Answer:

Step-by-step explanation:

a² + b² = c²

3.6² + b² = 7.4²

b² = 7.4² - 3.6² = 41.8

b = √41.8

Write the equation for the linear function. A={(x,y): (0,2)(-2,0)(-3,1)...}

Kay [80]

Answer:

y=x+2

Step-by-step explanation:

To find the equation of a line or linear function, you need at least two points that lie on the line. This is to find the slope or gradient of the line if it's not given. Let's use the two points (0,2) and (-2,0). The first coordinate in each point is X and the second is the y coordinate.

GRADIENT/SLOPE=[y1-y2]/[x1-x2]

=[2-0]/[0-2]=1

The equation of a linear function is given. by Y-y1=m(X-x1)

Y-2=1(X-0)

Y=X+2

VERIFICATION OF SOLUTION

You may want to verify whether you are right by substituting values of x to see if you can obtain corresponding y values.

Example: if x=0, y=0+2=2.This confirms first point

Cammie can mow 1/2 acre in 25 minutes. If her rate is constant, Cammie says she can mow 1 1/4 acres in one hour. Is Cammie corre

Sergeu [11.5K]

Answer: No, Cammie is not correct. She can mow $1\frac{1}{5}\ acres$ in one hour (See explanation).

Step-by-step explanation:

Convert the mixed number to an impoper fraction:

1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.

2. The denominator does not change.

Then:

$1\frac{1}{4}=\frac{(1*4)+1}{4}=\frac{5}{4}$

Let be "x" the acres Cammie can mow in one hour.

You know that she can mow $\frac{1}{2}\ acre$ in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):

$\frac{\frac{1}{2}}{25}=\frac{x}{60}$

Solving for "x", you get:

$\frac{\frac{1}{2}}{25}=\frac{x}{60}\\\\(60)(\frac{1}{50})=x\\\\x=\frac{6}{5}$

Convert from improper fraction to mixed number:

1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.

2. The remainder is 1. This will be the numerator.

3. The denominator does not change.

Then:

$x=1\frac{1}{5}$

Therefore, she can mow $1\frac{1}{5}\ acres$ in one hour.

PLEASE I HAVE TO GET THESE RIGHT!!!!! i NEED HELP! IM STUCK!!!!!!!

topjm [15]

Inversely proportional:

y = constant/x, or y*x = constant. Let's see which give the *same* product:

a) 6*1.5 = 5*1.25 NO
b) 5*2 = 4*3 NO
c) 4*2.25=6*1.5 YES!!!
d) 4.5*3 = 6*4 NO

So, C)!!!
