Answer:
The height of the Eiffel Tower will be 318 feet.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that Lizbeth is 5.5 ft tall, seeing the top from 318 feet away, making an angle of elevation to be 72⁰.
The diagram makes a right-angled triangle.
Given the angle = Ф = 72⁰ Adjacent = a = 5.5 ft Opposite = b = 318 ft Hypotenuse = the height of the Eiffel Tower = c ?
Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:
[tex]c=\sqrt{a^2+b^2}[/tex]
[tex]a=5.5[/tex][tex]b=318[/tex][tex]c=\sqrt{5.5^2+318^2}[/tex]
[tex]c=318[/tex] feet
Therefore, the height of the Eiffel Tower will be 318 feet.
A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A
lacrosse goalie saved 7 of 11 shots. How many additional consecutive saves s must the goalie make to
raise his save percentage to 0.850?
Answer:
The goalie needs to make 16 more saves in a row.
Step-by-step explanation:
Let n be the number of additional saves needed.
[tex]\frac{7+n}{11+n}\geq 0.85[/tex]
[tex]7+n\geq 0.85(11+n)\\[/tex]
[tex]7+n\geq 9.35+0.85n[/tex]
[tex]0.15n\geq 2.35[/tex]
[tex]n\geq 15.66[/tex]

Which equation could be used to find the length of the hypotenuse?
if the value of c is negative, you would need zero pairs to model the factorization of the polynomial. the x-tiles on the board determine what the constants are in the factors. the product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. opposite signs on the constants will result in a negative value for c when multiplying the factors.
Answer:
value of c is negative
constant are in factor bla bla.

c. [tex]\frac{31}{7}[/tex]
d. [tex]\frac{11}{16}[/tex]

Step-by-step explanation:
a. [tex]\frac{-1}{6}\\[/tex] * 2[tex]\frac{3}{4}[/tex] =
2[tex]\frac{3}{4}[/tex] = [tex]\frac{4*2+3 }{4}[/tex]= [tex]\frac{11}{4}[/tex]
[tex]\frac{-1}{6}\\[/tex] * [tex]\frac{11}{4}[/tex] = [tex]\frac{-1*11}{6*4}[/tex] = [tex]\frac{-11}{24}[/tex]
b. [tex]\frac{3}{16}[/tex] / [tex]\frac{-1}{8}[/tex] =
[tex]\frac{3}{16}[/tex] * [tex]\frac{8}{-1}[/tex] = [tex]\frac{3*8}{16*-1} \\[/tex] = [tex]\frac{24}{-16}[/tex] = [tex]\frac{-3}{2} \\[/tex]
c. [tex]\frac{-31}{56}[/tex] * [tex]\frac{-8}{1}[/tex] = [tex]\frac{31}{7}[/tex] (you can reduce 8 & 56 by dividing by 8: 56/8=7 & -8/8= -1)
d. 1 [tex]\frac{7}{8}[/tex] / 2[tex]\frac{8}{11}[/tex] =
1 [tex]\frac{7}{8}[/tex] = [tex]\frac{8*1+7}{8}[/tex] = [tex]\frac{15}{8}[/tex]
2[tex]\frac{8}{11}[/tex] = [tex]\frac{11*2+8}{11}[/tex] = [tex]\frac{30}{11}[/tex]
[tex]\frac{15}{8}[/tex] * [tex]\frac{11}{30}[/tex] = [tex]\frac{11}{16}[/tex] (you can reduce 15 & 30 by dividing by 15: 15/15=1 & 30/15 = 2)

If the geometric mean between two number is 8 and one of the numbers is 2, what is the value of the other number?
Answer: 14
Step-by-step explanation: To find the mean you have to add the two numbers and divide by the amount of numbers (which is 2). 14 plus 2 is equal to 16. and 16 divided by two is equal to eight

Need help with question 12 ASAP ill love you forever
Answer:
A
Step-by-step explanation:
You solve for x so,
Y=3-5x
y-3=5x <----- subtract by 3
3/5+y=x <------ divide by -5
Also (3/5,0) is at the x value
-7x-2y= -13
x-2y= 11
Solve the question with substitution and show work
Answer:
x=3,y= -4
Step-by-step explanation:
ii) x-2y=11
x=11+2y-----(i)
Now,
i) -7x-2y= -13
or, -7(11+2y)-2y= -13
or, -77-14y-2y = -13
or -14y-2y = -13+77
or -16y = 64
or y =64÷(-16)
:: y = -4
Again,
(ii) x-2y= 11
or x-2(-4)= 11
or x+8 = 11
or x = 11-8
:: x = 3

6 Find the value of x' and each angle
The value of x=10 and m∠SOP=50° and m∠ROQ=50° .
When two straight lines intersect each other at a point then vertical angles are formed , there are two pair of vertically opposite angles and also , the vertically opposite angles are equal.
In the given question
m∠SOP = (5x)° ...(i)
and
m∠ROQ = (4x+10)° ...(ii)
and Since the angles m∠SOP and m∠ROQ are vertically opposite , they will be equal .
On equating we get ,
m∠SOP=m∠ROQ
Substituting the values from equation (i) and (ii) we get ,
5x=4x+10
5x-4x=10
x=10.
Substituting the value of x in equation (i) we get ,
m∠SOP = (5*10)° = 50°
Substituting the value of x in equation (ii) we get ,
m∠ROQ = (4*10+10)° = (40+10)° = 50°
Therefore , the value of x=10 and m∠SOP=50° and m∠ROQ=50° .

Answer:
z=8
Step-by-step explanation:
Answer:
z = 8
Step-by-step explanation:
Given
- 9z - 7 = - 23 - 7z ( add 9z to both sides )
- 2z - 7 = - 23 ( add 7 to both sides )
- 2z = - 16 ( divide both sides by - 2 )
z = 8
Calculate the height of a right circular cylinder with a surface area of 300 square inches and a radius of 5 inches. a. 2.45 inches c. 8.25 inches b. 4.55 inches d. 3.65 inches
Answer:
The height of the right circular cylinder is 4.55 inches ⇒ b
Step-by-step explanation:
The formula of the surface area of a right circular cylinder is
S.A = 2πrh + 2πr², where
r is its radiush is its height∵ The surface area of a right circular cylinder is 300 square inches
∴ S.A = 300 in.²
∵ Its radius is 5 inches
∴ r = 5 in.
∵ π = 3.14
→ Substitute them in the rule above
∵ 300 = 2(3.14)(5)(h) + 2(3.14)(5)²
∴ 300 = 31.4h + 157
→ Subtract 157 from both sides
∵ 300 - 157 = 31.4h + 157 - 157
∴ 143 = 31.4h
→ Divide both sides by 31.4
∵ 4.554140127 = h
∴ 4.55 = h
∴ The height of the right circular cylinder is 4.55 inches
