Evaluate the expression.62−4÷2 62−4÷2
Answer:
[tex]62 - (4 \div 2)62 - (4 \div 2) \\ = 62 - (2 \times 62) - 2 \\ = 60 - 124 \\ = - 62[/tex]
or if the question is 62 - 4 ÷ 2
= 62-(4÷2)
=62-2
=60
Sec x -tan x sin x =1/secx
Help me prove it
Answer:
L.H.S. = [tex]\frac{1}{cosx} -\frac{sinx}{cosx}sinx[/tex]
= [tex]\frac{1}{cosx} - \frac{sin^2x}{cosx}[/tex]
= [tex]\frac{1-sin^x}{cosx} = \frac{cos^2x}{cos x}[/tex]
= cos x = 1/secx
Step-by-step explanation:
Hey there!
Given;
sec x - tan x . sin x = 1/(sec x).
~ Taking LHS.
= sec x - tan x . sin x
= 1/(cos x) - (sin x/cos x) . sin x { Using formula sec x = 1/cos x and tan x = (sin x/cos x)}
~ Multiply (sin x) and (sin x).
[tex] = \frac{1 - { (\sin(x) )}^{2} }{ \cos(x) } [/tex]
~ Use formula 1-sin²x= cos²x
[tex] = \frac{ {cos}^{2} x}{ \cos(x) } [/tex]
~ Cancel cos x.
= cos x
= 1/sec x { cos x = 1/sec x}
→ RHS proved.
Hope it helps.....

Answer:
The expression is: [tex]-30n + 70 = -80[/tex]
Step-by-step explanation:
Given
[tex]n = 5[/tex]
Multiply both sides by 3
[tex]3 * n = 5 * 3[/tex]
[tex]3n = 15[/tex]
Subtract both sides by 7
[tex]3n - 7 = 15 - 7[/tex]
[tex]3n - 7 = 8[/tex]
Multiply both sides by -10
[tex]-10(3n - 7) = -10*8[/tex]
[tex]-30n + 70 = -80[/tex]
To verify: Substitute 5 for n
[tex]-30 * 5 + 70 = -80[/tex]
[tex]-150 + 70 = -80[/tex]
[tex]-80 =-80[/tex] ---- Verified

If triangle A B C is congruent to triangle D E F, the measure of angle A equals 55 degrees, and the measure of angle E equals 25 degrees, what is the measure of angle C?
A. 25°
B. 55°
C. 80°
D. 100°
Answer:
D. 100
Step-by-step explanation:
Answer:
100°
Step-by-step explanation:
Since ΔABC ≅ Δ DEF, and the sum of the measures of the interior angles of a triangle is 180°, subtract the given angle measurements from 180°.
∠A ≅ ∠D, ∠B ≅ ∠E, ∠C ≅ ∠F (The vertices are written in this order because they are corresponding angles.)
180° - 55° = 125° - 25° = 100°
∠C is 100°

6051 was rounded to the nearest one. What is the lower bond ?
Answer:
6050.5
Step-by-step explanation:
The key to this is "rounded to the nearest one"
If the question was to say "round to the nearest 10" you would do 10÷2 = 5
Always divide by 2
1 ÷2 = 0.5
6051 - 0.5 = 6050.5
If it was upper bond it would be:
6051 + 0 5 = 6051.5

5. Si un paquete de 100 hojas iguales mide 1 cm de altura, ¿cuál
es el grosor de una hoja?
Responder:
0,01 cm
Explicación paso a paso:
Dado que :
Un paquete de 100 hojas iguales = 1cm de alto
Esto significa que el grosor del paquete es de 1 cm de alto.
Dado que las hojas son iguales, el grosor de una sola hoja será:
(Espesor del paquete completo / número de hojas en el paquete)
(1 cm / 100)
= 0,01 cm
Usando proporciones, se encuentra que el grosor de una hoja es de 0.01 cm.
Esto problema é solucionado por proporciones, se utilizando de una regla de três.Hay 100 hojas iguales, al todo midiendo 1 cm de altura. ¿Cuál es la equivalente medida de 1 hoja?La regla de três es dada por:
100 hojas - 1 cm
1 hoja - x cm
Aplicando multiplicación cruzada:
[tex]100x = 1[/tex]
[tex]x = \frac{1}{100}[/tex]
[tex]x = 0.01[/tex]
Por eso, el grosor de una hoja es de 0.01 cm.
Un problema similar, que también envolve proporciones, es dado en https://brainly.com/question/24615636
The intensity of the sound, I watts/m², received from a loudspeaker is
inversely proportional to the square of the distance, d metres, from the
loudspeaker.
When d = 2,1 = 30
Work out the value of I when d = 10
PLEASE HELP
Answer:
The value of I for d = 10 will be 1.2 watts/m^3
Step-by-step explanation:
Let I be the intensity of sound and d be the distance
According to given statement, "The intensity of the sound, I watts/m², received from a loudspeaker is inversely proportional to the square of the distance, d meters, from the loudspeaker. "
[tex]I \propto \frac{1}{d^2}[/tex]
Removing the proportionality symbol
[tex]I = \frac{k}{d^2}[/tex]
Putting d = 2 and I = 30
[tex]30 = \frac{k}{(2)^2}\\30 = \frac{k}{4}\\k = 30*4\\k = 120[/tex]
Putting the value of k in the equation
[tex]I = \frac{120}{d^2}[/tex]
Putting d = 10
[tex]I = \frac{120}{(10)^2}\\I = \frac{120}{100}\\I = 1.2[/tex]
Hence,
The value of I for d = 10 will be 1.2 watts/m^3

Solve. 3k -4 > 60 – k
Answer:
[tex]3k - 4 > 60 - k \\ = 3k + k > 60 + 4 \\ = 4k > 64 \\ = k > \frac{64}{4} \\ = k > 16[/tex]
Answer:
k > 16
Step-by-step explanation:
Solve it like an equation solving for k
Move the -4 to the other side by adding it to both sides.
3k -4 plus 4 > 60 plus 4 - k
You get 3k > 64 - k
now move the k from the right to the left by adding both sides by k
3k plus k > 64 - k plus k
You get 4k > 64
Now divide both sides by 4 so you get k alone on one side to solve for the inequality
4k/4 > 64/4
k > 16

D.

Answer:
Step-by-step explanation:
B 15%
Answer: The correct answer is D) 37%
Step-by-step explanation:
We can use our binomial model equation with all the relevant information to solve this problem simply. We just need to dissect the problem a bit to find relevant information. We know that out of 16 batteries in a pack (the number of trials in this case) we want to find the possibility of 1 of them (the number of successes) to be defective with a defective rate of 5% or 0.05. We simply input the data into our binomial formula given and solve for our answer of 37% I hope this answer has been of use.

Find the slope intercept equation of the line
PLEASE SOMEONE HELP WHO UNDERSTANDS HOW TO DO THESE BECAUSE I KEEP GETTING THE WRONG ANSWER!!!
Step-by-step explanation:
For every 3 blocks across, the line graph goes up by 2 blocks. Therefore the slope of the line is 2/3.
The line also intercepts the y-axis at -3.
Hence the slope-intercept form is y = 2/3 x - 3.
