Find the height of the cliff. If necessary, round to the nearest hundredth yard.
We are given a diagram showing a slope, and a vertical height. We now have what represents a right angled triangle. The distance from the base of the cliff to the end of the slope is given as 24 yards. The slope itself is 37 yards. We shall now determine the height of the cliff (from ground to top) as indicated.
Note that we shall use the Pythagoras' theorem which is;
[tex]c^2=a^2+b^2[/tex]Where we have
[tex]\begin{gathered} c=\text{hypotenuse (longest side)} \\ a,b=\text{other sides} \end{gathered}[/tex]We can now substitute the given values/side lengths and we'll have;

Annie's backyard deck cost $61.75 per square meter to build. The deck is 7 meters wide and14 meters long. How much did it cost to build the deck?
ANSWER
the cost to build the deck is $6051.5
EXPLANATION
Given that;
The length of the deck is 14 m
The width of the deck is 7m
1 m^2 is equivalent to $61.75
Follow the steps below to find the cost to build the deck
Step 1; Find the area of the deck
[tex]\begin{gathered} \text{ Recall, that the deck is a rectangular shape} \\ \text{ Area of a rectangle = length }\times\text{ width} \\ \text{ Area of a reactangle = 14 }\times\text{ 7} \\ \text{ Area of a rectangle = 98m}^2 \end{gathered}[/tex]Step 2; Find the total cost of the deck
Let x represents the total cost to build the deck
[tex]\begin{gathered} \text{ 1m}^2\text{ }\rightarrow\text{ \$61.75} \\ \text{ 98m}^2\text{ }\rightarrow\text{ \$x} \\ \text{ cross multiply} \\ \text{ 1m}^2\text{ }\times\text{ \$x = \$61.75 }\times\text{ 98m}^2 \\ \text{ Isolate \$x }\frac{}{} \\ \text{ \$x = }\frac{\text{ \$61.75}\times98\cancel{m^2}}{1\cancel{m^2}} \\ \text{ \$x = \$61.75 }\times\text{ 98} \\ \text{ \$x = \$6051.5} \end{gathered}[/tex]Therefore, the cost to build the deck is $6051.5
Callie's grandmother pledged R150, 00 for every mile Callie walked in her walk-a-thon. Callie walked 14.5 km. How much does her grandmother owe? ( assume 8 km = 5miles)
Given:-
Callie walked 14.5 km. And also given 8 km=5 miles.
At first we convert 14.5 km to miles. we get,
[tex]\begin{gathered} 14.5\times\frac{5}{8}=\frac{72.5}{8} \\ \text{ =9.0625} \end{gathered}[/tex]So 14.5 km is 9.0625 miles.
Callie's grandmother pledged Rs. 150 for every mile. so for 9.0625 miles it is,
[tex]9.0625\times150=1359.375[/tex]So her grandmother owe Rs. 1359.375

Moshde runs a hairstyling business from her house. She charges $42 for a haircut and style. Her monthly expenses are $1070. She wants to be able to put at least $1,249 per month into her savings account order to open her own salon. How many "cut & styles" must she do to save at least $1,249 per month?
ANSWER:
56 cut & styles
STEP-BY-STEP EXPLANATION:
They tell us that each haircut and style charges $42 and that the monthly expenses are $1070, he wants to save a total of $1249, with this information we can establish the following equation:
[tex]42x-1070=1249[/tex]Where x would be the amount of cut & styles, we solve for x:
[tex]\begin{gathered} 42x=1249+1070 \\ x=\frac{2319}{42} \\ x=55.2 \\ x\cong56 \end{gathered}[/tex]If you make a total of 55 cut & styles, the amount does not reach a total of $1249 per month, therefore, at least 56 cut & styles are needed, to achieve the monthly goal.
Amelia bought spider rings for Halloween goodie bags. She bought 13 packs of red rings, 16 packs of yellow rings, and 14 packs of green rings. If each pack had 12 rings, how many rings did Amelia buy?
We know that
• She bought 13 packs of red rings.
,• She bought 16 packs of yellow rings.
,• She bought 14 packs of green rings.
,• Each pack has 12 rings.
This problem is about multiplication, notice that each pack includes 12 rings, that means we need to multiply each pack by 12, in order to find the total number of rings of each color.
[tex]R=13\cdot12=156[/tex]There are 156 red rings.
[tex]Y=16\cdot12=192[/tex]There are 192 yellow rings.
[tex]G=14\cdot12=168[/tex]There are 168 green rings.
Now, we sum all these numbers to find the total
[tex]T=168+192+156=516[/tex]Therefore, there are 516 rings in total.determine whether the binomial expression is a factor to the following polynomial.[tex]p(x) = {x}^{3} - 9x + 1 \: \: \: \: \: \: \: \: \: (x - 3)[/tex]the binomial expression is (x-3) ^^answer choicesA. yesB. no
We can find if (x-3) is a factor by dividing P(x) by (x-3).
A simpler way is replacing x with 3 and if the value of P(x) is 0, then (x-3) is a factor of P(x). This is because x=3 is a root of P(x) and therefore it can be factorized with the term (x-3).
Then, we calculate P(3):
[tex]P(3)=3^2-9\cdot3+1=9-27+1=-17[/tex]As x=3 is not a root of P(x), then (x-3) is not a factor of P(x).

[tex]undefined[/tex]How many pounds of candy that sells for $0.85 per Ib must be mixed with candy that sells for $1.22 per lb to obtain 9 lb of a mixture that should sell for $0.92 per lb? 50.85-per-lb candy: 73 lb (Type an integer or decimal rounded to two decimal places as needed.) $1.22-per-b candy
This system gives two equations
[tex]\frac{0.85x+1.22y}{9}=0.92[/tex][tex]x+y=9[/tex]where x is the number pounds of $0.85/lb candy and y is the number of pounds of $1.22/lb candy.
The solution to the system is
[tex]x=7.297[/tex][tex]y=1.70[/tex]Hence, 7.297 lb of $0.85 candy is required in order that if we mix them with 1.70 lb of $1.22 candy, we will get a 9 lb solution of 0.92 /lb candy.
the line contains the point (-3,5) and is perpendicular to the line y=3x-4
two lines are perpendicular when the multiplication of their slopes is equal to -1. The slope of y = 3x - 4 is 3. Then the slope of a perpendicular line is:
[tex]\begin{gathered} m\cdot3=-1 \\ m=-\frac{1}{3} \end{gathered}[/tex]Slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept. Replacing with point (-3, 5) and m = -1/3, we get:
5 = -1/3(-3) + b
5 = 1+ b
5 - 1 = b
4 = b
Then, the equation is:
y = -1/3x + 4
Type the correct answer in the box. Use numericals instead of words. 5 less than a number is equivalent to 1 more than three times the number. The number is _____.
Answer:
2
Explanation:
Let the number be x
5 less than a number is expressed as x - 5
1 more than three times the number is expressed as 3x + 1
Equate both expression and find the number
x - 5 = 3x+1
x - 3x = 1 - 5
-2x = -4
x = -4/-2
x = 2
Hence the number is 2
Can someone please help me find the value of X?
Remember that
the sum of the interior angles in any polygon is equal to
S=180(n-2)
where
n is the number of sides of polygon
In this problem
we have
n=6 (hexagon)
so
substitute
S=180(6-2)
S=720 degrees
step 2
Adds the interior angles
720=120+(5x-6)+(4x+14)+(7x)+(8x-8)+(6x)
solve for x
combine like terms
720=30x+120
30x=720-120
30x=600

We are shown points A, B, C, and D on a number line.
We are asked to find out which point shows the number with the greatest absolute value?
Recall that the absolute value of a number is always positive.
The negative values of points A and B will become positive.
As you can see from the number line, point A is closer to -40 and the point D is closer to 30
The absolute value of point A will be closer to |-40| = 40
Since 40 is greater than 30, point A shows the number with the greatest absolute value.
Therefore, the correct answer is Point A.

Hi, what is the LCM of the numbers 3 and 15
Answer:
15
Step-by-step Explanation:
LCM is the least common multiple, that is, is the least number that is a multiple of both numbers.
To find it, first, let's write the multiples of 3:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...
Now, let's write the multiples of 15:
Multiples of 15: 15, 30, 45, ...
If you compare the multiples of 3 and 5, we can see that they have some common multiples, as 15 and 30.
From this common multiples, 15 is the smallest number. So, 15 is the LCM of 3 and 15.
