the hypotonuse of a right triangle measures 15cm and one of its legs meauseres 8cm find the measure of the other leg
Answer:
7cm
Step-by-step explanation:
15 - 8
Hypotenuse is the longest side
I need the answer in the next 6 hours
Answer:
180m
Step-by-step explanation:
The figure shown in the picture is a right triangle.
We have two of it's sides and need to find the hypotenuse (the side in front of the right angle).
To find that we must use the Pythagorean theorem:
[tex]c^{2} = {a}^{2} + {b}^{2} [/tex]
Side a is 400m and side b is 300m.
Therefore:
[tex]c^{2} = {300}^{2} + {400}^{2} [/tex]
[tex]c = \sqrt{300 \times 300 + 400 \times 400} = 500[/tex]
Now that we know that side c is 500m we must just substract the distance between Marla and the dock with the lenght of the side to find the answer
500 - 320 = 180m
Answer:
She is 180m from the information Center
She walked 240m from the parking lot to the lake.

Absolute minimum and maximum values of [tex]f(x)=2x^{3}-3x^{2} -12x+1[/tex] on the interval [-2,3]
Step-by-step explanation:
[tex]f'(x)=6x^{2}-6x-12[/tex]
So f'(x)=0:
x^2 - x - 2 = 0
(x-2)(x+1)=0
x=-1, 2
So we need to find the value of f at those critical points and also at the endpoints of the interval
f(-1)=-2-3+12+1=8
f(2)=16-12-24+1=-19
f(-2)=-16-12+24+1=-3
f(3)=54-27-36+1=-8
so the max is 8 and the min is -19

A parachutist’s speed during a free fall reaches 165 feet per second. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 10 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answer.
Answer:
[tex]x=750m[/tex]
Step-by-step explanation:
[tex]Assuming[/tex] [tex]That[/tex]:
[tex]1m=3.3ft[/tex]
We can make the conversion from feet per second to meters per second with this procedure:
[tex](165 \frac{ft}{s} ) (\frac{1m}{3.3ft} )=50\frac{m}{s}[/tex]
Let [tex]x[/tex] be the amount of meters the parachutist will fall during 15 seconds of free fall
Having that in 1 second the parachutist falls 50 meters, we can calculate [tex]x[/tex] :
[tex]x=(50\frac{m}{s} )(15s)[/tex]
[tex]x = 750 m[/tex]

Answer:
[tex]p=-10[/tex]
Step-by-step explanation:
Given the following question:
[tex]-5=p+5[/tex]
In order to find the answer, we subtract 5 on both sides:
[tex]-5=p+5[/tex]
[tex]5-5=0[/tex]
[tex]-5-5=-10[/tex]
[tex]-10=p[/tex]
[tex]p=-10[/tex]

Find the value of x.
to
890
121°
Answer:
32°
Step-by-step explanation:
Let the angle next to 121° be a,
a+121°=180°
a=180-121=59°
Now we have a=59°,
89° (given) and x, these threes form a triangle, therefore,
x+a+89°=180°
×+59°+89°=180°
x+148°=180°
x=180°-148°
x=32°

Thankuhh☃️
Answer:
1) [tex]x = -1[/tex] || 2) [tex]x = 10[/tex]
Explanation:
1)
→ [tex]\log _3\left(\frac{1}{3}\right)=x[/tex]
→ [tex]\frac{1}{3} = 3^x[/tex]
→ [tex]3^{-1} = 3^x[/tex]
→ [tex]x = -1[/tex]
2)
→ [tex]\log _3\left(x-1\right)=2[/tex]
→ [tex]x - 1 = 3^2[/tex]
→ [tex]x -1 = 9[/tex]
→ [tex]x = 9 +1[/tex]
→ [tex]x = 10[/tex]

PLS GIVE WORKING OUT
THANKS :)
Answer:
for a three hour job it would be £105
Step-by-step explanation:
to find how much he charges an hour, we divide 140 by 4 and get 35.
from there we multiply 35(£) by 3(hours) and get 105(£).

I don't understand this please help
Answer:
350
Step-by-step explanation:
The solution to the equation can be found by multiplying by the denominator, then dividing by its coefficient.
[tex]0.22 = \dfrac{77}{x}\qquad\text{given}\\\\0.22x = 77\qquad\text{multiply by $x$}\\\\x=\dfrac{77}{0.22}=350\qquad\text{divide by the coefficient of x}[/tex]
The missing value in the fraction is 350.
__
Additional comment
Here, we have rewritten the percentage as a decimal fraction. You could also rewrite it as a ratio of two integer: 22% = 22/100. Sometimes there is confusion about percentages. It can help to think of the % symbol as meaning /100:
22% = 22/100
Of course, that is "twenty-two hundredths" or 0.22.
If you just write the problem using 22/100 for 22%, then you get the proportion ...
22/100 = 77/x
22x = 7700 . . . . . "cross multiply" (multiply by 100x)
x = 7700/22 = 350 . . . . divide by the coefficient of x
__
If you're paying attention, you see that the solution of this kind of equation has the appearance that the denominator variable and the left-side value are simply swapped:
[tex]0.22 = \dfrac{77}{x}\ \leftrightarrow\ x=\dfrac{77}{0.22}[/tex]
Effectively, we have multiplied both sides of the equation on the left by x/0.22. There is a property of equality that lets us do that. There is no such thing as a property of equality that says "swap with denominator." You must always pay attention to what is allowed by the properties of equality.
