Help me find x please
Answer:
x = 14°
Step-by-step explanation:
We can see that these angles are supplementary.
Set up an equation
x + 96 + 5x = 180
6x + 96 = 180
subtract 96 from both sides
6x = 84
x = 14
Thus, we have our answer

Answer:
x=11°
<Bec = 33°
<Ced = 39°
Step-by-step explanation:
That's a right angle so it would be 90 degrees angle.
18+3x+4x-5=90
Lets simplify it to make it easier to work out by collecting like terms.
First all the variable 3x+4x=7x
Then the numbers 18+-5=13
13(-13)+7x = 90(-13)take away 13 from both sides
(Opposite operators EG, Add becomes subtract)
7x = 77 then divide 7 from both sides
x=11
Then work out
3x11=33 degrees
4x11=44-5=39 degrees
To double check 39+33+18=90 degrees
A linear sequence (i.e. where the 1st difference is always the same) has 5th term 6 and 92nd term 354. What is the 57th term?
Answer:
I dont know xDDDDDDDDDD
Answer:
a₅₇ = 214
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₅ = 6 and a₉₂ = 354 , then
a₁ + 4d = 6 → (1)
a₁ + 91d = 354 → (2)
Subtract (1) from (2) term by term to eliminate a₁
0 + 87d = 348
87d = 348 ( divide both sides by 87 )
d = 4
Substitute d = 4 in (1) and solve for a₁
a₁ + 4(4) = 6
a₁ + 16 = 6 ( subtract 16 from both sides )
a₁ = - 10
Then
a₅₇ = - 10 + (56 × 4 ) = - 10 + 224 = 214
The milligrams of a asprin in a persons body is given by the equation a=500 (3/4)^t where the t is the numbers of hours since the patient took the medicine. How much asprin will be in the patients body after two hours
Answer: 281.25 milligram
Step-by-step explanation:
Given
Milligrams of aspirin left after t hours is given by
[tex]\Rightarrow a=500(\frac{3}{4})^t[/tex]
for [tex]t=2\ hr[/tex]
[tex]\Rightarrow a=500(\frac{3}{4})^2\\\Rightarrow a=500\times (0.75)^2=281.25\ \text{milligram}[/tex]
what is 2.38÷2.8
show all working
Answer:
the answer is 0.85 of 2.38 ÷ 2.8
Answer:
0.85
Step-by-step explanation:
[tex]\frac{2.38}{2.8} =\frac{2.38}{2.8}*\frac{100}{100}=\frac{2.38*100}{2.8*100}=\frac{238}{280}\\\\\frac{238}{280}=\frac{238}{280}/\frac{14}{14} =\frac{238/14}{280/14}=\frac{17}{20}\\\\\frac{17}{20}=\frac{17/2}{20/2}=\frac{8.5}{10}=0.85[/tex]

A line passes through the point (2,1) and has a slope of 7/2 Find
the equation of the line.
Answer:
1/7 and 2/2
Step-by-step explanation:
Can someone help me please?
Answer:
So the answer is 2^-3
Step-by-step explanation:
The principle is the same no matter what the base.
Log_2 (7) + Log_2(3/28) - Log_2(6)
+ means multiply
- means divide
Log_2(7 * 3/28 /6)
Log_2(7/6 * 3/28)
Log_2(1/2 * 1/4) 3 divides into 6 twice. 7 divides into 28 four times
log_2 (1/8)
This is equivalent to 2^(-3)
I think you might need Desmos for graphing?? Explain your answer!
Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.
The vertex point is (0,12)
the axis of symmetry is 0
The zeros are (-4,0) and (4,0)
using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)
Your answer is 8

PLEASE HELP!!!! The class was given this problem and asked to solve for "x". Craig says that x = 11/cos(37). Laura disagrees and says that x = 11/sin(53). Who (if anyone) is correct?
Answer:
both
Step-by-step explanation:
they are both correct. sin and cosine are complements (90-x) of each other ( that's where cosine gets its name).
What is the y-intercept of the line that is perpendicular to y = −3x − 5 and passes through the point (−3, 7)?
NEED BEFORE 11:59 ASAP
Answer:
b=8
Step-by-step explanation:
Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.
we are given the line y=-3x-5
we need to find the slope of the new line. To do that, we can use this equation:
-3m=-1
divide by -3 on both sides
m=1/3
so the slope of the perpendicular line is 1/3
We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need
so far our equation is:
y=1/3x+b
we need to find b
we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b
so:
7=1/3(-3)+b
7=-1+b
8=b
so the y intercept of the line is 8; as a point it's (0,8)
hope this helps!

La mère de Julien lui a choisi un forfait de téléphone mobile
à 14,90 €. Elle explique à son fils que, pour ce prix, il peut téléphoner

On his death, a wealthy businessman left R132 000 to charity. He declared that the money should be given to the following charities: 'The Reach for a Dream Foundation', NSPCA and Smile, in the following ratio 3 : 4 : 5.
Determine the amount each foundation received.
Answer:
The Reach for a Dream Foundation received R33000, NSPCA received R44000, and Smile received R55000.
Step-by-step explanation:
Total money for charity = R132,000
Ratio:
3 : 4 : 5
Charities:
The Reach for a Dream Foundation : NSPCA : Smile
x : y : z
3x + 4y + 5z = R132000
Charity 1 = Charity 2 = Charity 3
x = y = z
3x + 4x + 5x = R132000
x = 11000
The Reach for a Dream Foundation:
3(11000) = R33000
NSPCA:
4(11000) = R44000
Smile:
5(11000) = R55000
Double Check:
R33000 + R44000 + R55000 = R132000
