g= number of grasshoppers= twice number of crickets= 2c
T= total number of both= 561
If you add the number of crickets and the number if grasshoppers, you'll get a total of 561.
c + g= T
c + g= 561
Now we also know that grasshoppers are 2c (twice the crickets). Substitute 2c for g in the equation to solve for c.
c + g= 561
c + 2c= 561
combine like terms
3c= 561
divide both sides by 3
c= 187 crickets
Substitute number of crickets back in equation to find g.
c + g= 561
187 + g= 561
subtract 187 from both sides
g= 374 grasshoppers
CHECK:
Since grasshoppers are twice the number of crickets, then multiplying the number of crickets by two should equal the number of grasshoppers.
187 * 2= 374
374= 374
ANSWER: 187 crickets and 374 grasshoppers

Kareem wants to wallpaper the back wall of his bedroom. The wall is in the shape of a rectangle. Its length is
13 feet and its width is 12
feet. The wallpaper costs $8
for each square foot. How much will wallpaper cost for the wall?
Answers
The first step in solving this problem is to compute for the area of the rectangular wall. The formula in computing the area of a rectangle is:
A = LW
Substituting the given measurements in the problem to the formula:
A = 13 (12)
A = 156
Therefore, the area of the wall is 156 square feet. To compute the wallpaper cost of the wall, you have to multiply the cost per square foot to the total area.
$8 per square foot x 156 square feet = $1,248
Therefore, the wallpaper cost for the wall is $1,248

Answers
[tex]y=41* 0.95^{x} [/tex]
a. Does the exponential function represent growth or decay?
To find out if this is growth or decay we need to observe number that is connected with x. If number is less than 1 we have decay and if it is greaer than 1 we have growth.
In our case we have number 0.95 which is less than 1 so we have decay.
b. Estimate the difference between finishing times in 1990.
x represents the number of years since 1972.
[tex]x=1990-1972=18[/tex]
Now we insert this number into equation to get solution.
[tex]y=41* 0.95^{18} = 16.29[/tex]
c. Predict the difference between finishing times in 2005.
[tex]x=2005-1972=33[/tex]
[tex]y=41* 0.95^{33} = 7.55[/tex]

List the angles of triangle DEF in order from smallest to largest measure if DE = 7, EF = 9, and DF = 3.
∠D, ∠E, ∠F
∠E, ∠F, ∠D
∠F, ∠E, ∠D
∠D, ∠F, ∠E
Answers
∠D is opposite side EF. ∠E is opposite side DF. ∠F is opposite side DE. The sides that are the smallest correspond with the smallest angles, and the sides that are the largest correspond with the largest angles.
First, you should draw a picture of triangle DEF and label all of the sides. Then, you will have an idea of what the triangle looks like and the relative size of the angles.
You can also look at the side opposite of the angle. The larger the opposite side, the larger the angle.
Quadrilateral ABCD is inscribed in circle O.
What is m∠B ?
Enter your answer in the box.
Answers
The measure of angle B is 125 degrees in the given quadrilateral inscribed in circle O.
In a quadrilateral inscribed in a circle, opposite angles are supplementary.
Therefore, we can set up the equation:
∠A + ∠C = 180 degrees
Substituting the given values:
(2x-7) + (x+4) = 180
Combining like terms:
3x - 3 = 180
Adding 3 to both sides:
3x = 183
Dividing both sides by 3:
x = 61
Now we can find ∠B:
∠B = 2x + 3
∠B = 2(61) + 3
∠B = 122 + 3
∠B = 125
Therefore, m∠B is equal to 125 degrees.

Factored Form is (x+4)(x+2)
Expanded Form is x^2+6x+8
----------------------------------------------------------
----------------------------------------------------------
Explanation:
The factored form is simply a matter of reading off the values from the given image. There isn't much work to show here.
Along the left side we have x and 4 so x+4 is one of the factors. Along the bottom we have x and 2, so x+2 is another factor
The two factors are (x+4) and (x+2) so that's why the factored form is (x+4)(x+2)
-------------------------------
Let's expand out the factored form
The overall rectangle is broken up into four parts. I'll label the four smaller rectangles as...
Rectangle A in the upper left corner (this rectangle is x by x)
Rectangle B in the upper right corner (this rectangle is 2 by x)
Rectangle C in the lower left corner (this rectangle is x by 4)
Rectangle D in the lower right corner (this rectangle is 2 by 4)
The idea is that adding the areas of rectangles A through D leads us to the overall area for this largest rectangle.
Area of Rectangle A = (length)*(width) = x*x = x^2
Area of Rectangle B = (length)*(width) = 2*x = 2x
Area of Rectangle C = (length)*(width) = x*4 = 4x
Area of Rectangle D = (length)*(width) = 2*4 = 8
Notice we have the like terms 2x and 4x (areas of rectangle C and D respectively). They combine to 2x+4x = 6x
So after adding all the individual areas and combining like terms, we arrive at the fully expanded form of x^2+6x+8

check their difference, that much.
The interest is $8.77 owed in the amount of $900 for 9 months more than for 6 months.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, The rate of interest is in percentage r% and is to be written as r/100
To determine interest on the amount of $900 for 9 months
Here P = $900, R = 2.9% = 2.9/100, and T = 9/12 year
Interest = P × R × T
Interest = 900 × 2.9/100 × 9/12
Interest = $19.57
To determine interest on the amount of $900 for 6 months
Here P = $900, R = 2.4% = 2.4/100, and T = 6/12 year
Interest = P × R × T
Interest = 900 × 2.4/100 × 6/12
Interest = $10.80
The difference of interest is owed on $900 for 9 months then for 6 months: $19.57 - $10.80 = $8.77
Therefore, the interest is $8.77 owed in the amount of $900 for 9 months more than for 6 months.
