sladkih [1.3K]

Answer:

Thus, a product that normally costs $4 with a 70 percent discount will cost you $1.20, and you saved $2.80. You can also calculate how much you save by simply moving the period in 70.00 percent two spaces to the left, and then multiply the result by $4 as follows: $4 x . 70 = $2.80 savings.

One number is 6 less than 3times another number and their sum is 62. Find the numbers.

eduard

Answer: x=17, y=45

Explanation: Let the numbers be x and y.

We have,

3x−6=y

Also, x+y=62

Thus, x+3x=62+6

Or, x=17

Putting in the required values, we get y as 45

The area of ABED is 49 square units. Given AGequals9 units and ACequals10 units, what fraction of the area of ACIG is represent

Mrac [35]

Answer:

The fraction of the area of ACIG represented by the shaped region is 7/18

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the square ABED find the length side of the square

we know that

AB=BE=ED=AD

The area of s square is

$A=b^{2}$

where b is the length side of the square

we have

$A=49\ units^2$

substitute

$49=b^{2}$

$b=7\ units$

therefore

$AB=BE=ED=AD=7\ units$

step 2

Find the area of ACIG

The area of rectangle ACIG is equal to

$A=(AC)(AG)$

substitute the given values

$A=(9)(10)=90\ units^2$

step 3

Find the area of shaded rectangle DEHG

The area of rectangle DEHG is equal to

$A=(DE)(DG)$

we have $DE=7\ units$

$DG=AG-AD=9-7=2\ units$

substitute $A=(7)(2)=14\ units^2$

step 4

Find the area of shaded rectangle BCFE

The area of rectangle BCFE is equal to

$A=(EF)(CF)$

we have

$EF=AC-AB=10-7=3\ units$

$CF=BE=7\ units$

substitute

$A=(3)(7)=21\ units^2$

step 5

sum the shaded areas

$14+21=35\ units^2$

step 6

Divide the area of of the shaded region by the area of ACIG

$\frac{35}{90}$

Simplify

Divide by 5 both numerator and denominator

$\frac{7}{18}$

therefore

The fraction of the area of ACIG represented by the shaped region is 7/18

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

Mazyrski [523]

Answer:

Decrease of 63.5%.

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

$y = y(0)(1+r)^{x}$

In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.

In this question:

We have that:

$y = 3100(0.365)^x$

$1 - r = 0.365$

$r = 0.365 - 1 = -0.635$

So a decrease of 63.5%.
