Answer:
The answer is 5 cards.
Step-by-step explanation:
Yu have to add 29 and 16 . When yu do that yu get 45 cards total. Divide 45 by 9 (friends) yu get 5 cards per person.
Find the total surface area of the
following square pyramid:
9 cm
10 cm
SA = [?]cm2
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
Answer:
SA = [280] cm 2
Step-by-step explanation:
For Lateral Area the formula is 4(1/2 10 x 9)
But the 1/2 makes it 4(1/2 5 x 9)
Then you multiply 5 x 9 = 45 then multiply 45 by the 4 and get 180
Then for Surface Area you put in (180 + 100) = 280
You get the 100 by multiplying 2 of the base numbers together.

how you to transform a polynomial equation in standard form? state some steps
Answer:
A very common way to transform a polynomial equation in standard form is usually by writing a polynomial in its standard form.
This is mainly achieved by checking the degree of the terms involved and writing them in the order of degree which should follow the pattern of from highest to lowest, left to right.
If AB undergoes a dilation of k=1/3 centered at (-3,2) then A’ will have the coordinates:
Answer:
(-3,2)
Step-by-step explanation:
It was correct on mine
The coordinate of A' after dilation of k = 1/3 is, (- 1, 2/3)
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
We have to given that;
⇒ AB undergoes a dilation of k = 1/3 centered at point (-3, 2).
Now,
The coordinate of A' after dilation of k = 1/3 is,
⇒ (1/3 × - 3, 1/3 × 2)
⇒ (- 1, 2/3)
⇒ (- 1, 0.67)

A man wants to cut down a tree in his yard. To ensure that the tree doesn’t hit anything he needs to know the height of the tree. He measures his distance from the tree at 18 meters and the angle of elevation to the tree at 80 degrees. What is the height of the tree to the nearest tenth of a meter?
Answer:
[tex]\boxed {\boxed {\sf 102.1 \ meters}}[/tex]
Step-by-step explanation:
Let's assume the tree forms a right angle with the ground.
The distance from the tree to the man is 18 meters. The angle of elevation, which is 80 degrees, is the angle from where the man is to the top of the tree. We want to find the height of the tree, which we can call x.
Let's draw a diagram. (not to scale)
We can use sine (opposite/hypotenuse), cosine (adjacent/hypotenuse) or tangent (opposite/adjacent). We base the sides off of the elevation angle.
x is opposite the elevation angle and 18 is adjacent to the angle. So, we must use tangent.
[tex]tan(\theta)=opposite/adjacent[/tex]
The angle (θ) is 80. The opposite is x. The adjacent is 18.
[tex]tan(80)=x/18[/tex]
Now, solve for x by isolating it.
x is being divided by 18. The inverse of division is multiplication. Multiply both sides of the equation by 18.
[tex]18*tan(80)=x/18*18[/tex]
[tex]18*tan(80)=x[/tex]
[tex]18*5.67128182=x[/tex]
[tex]102.0830728=x[/tex]
Round to the nearest tenth. The 8 in the hundredth place tells us to round up.
[tex]102.1\approx x[/tex]
The height of the tree is about 102.1 meters.

rema purchased 18 ounces of gold in 2005 for $414 per ounce in order to try to diversify her investment portfolio. She sold a third of her holdings in gold in 2009 at a price $953 per ounce. She sold the rest of her gold holdings in 2010 for $1,367 per ounce.
What is Prema’s profit in 2009 and 2010?
Given :
Rema purchased 18 ounces of gold in 2005 for $414 per ounce in order to try to diversify her investment portfolio.
She sold a third of her holdings in gold in 2009 at a price $953 per ounce. She sold the rest of her gold holdings in 2010 for $1,367 per ounce.
To Find :
What is Prema’s profit in 2009 and 2010.
Solution :
Price of one third ounces of gold, in 2005 is :
P = $414/3 = $138 .
Profit from selling them in 2009 is :
P1 = $(953 - 138) = $815 .
Profit from selling them in 2010 is :
P2 = $( 1367 - ( 414 - 138 ) ) = $1091 .
Therefore, Prema's profit in 2009 is $815 and 2010 is $1091.
Hence, this is the required solution.

Step one:
given data
Initial account balance= $7200
we are told that the decrease was by 24.5%
Step two:
1. How much is this decrease in dollars?
let us solve for 24.5% of $7200
=24.5/100*7200
=0.245*7200
=1764
the decrease is $1764
2. How much money was in her account at the end of last year?
the final account balance is

Separate 185 into two parts so that one part is 31 more than the other part. Find each part.
9514 1404 393
Answer:
108, 77
Step-by-step explanation:
Let x represent the larger part. Then ...
x + (x -31) = 185
2x = 216
x = 108
x -31 = 77
The two parts are 108 and 77.
