Answer:
83 and 97
Step-by-step explanation:
Supplementary angles are two angles with a sum of 180 ∘
small angle = x
large angle = x+14
x + (x+14) = 180
2x +14 = 180
2x= 166
x = 83
large = 83 +14 = 97
83+97 = 180

F is inversely proportional to d^2.
When F = 5, d = 9
Work out d (positive value rounded to 2 DP) when F = 3
Answer:
11.6
Step-by-step explanation:
F = k/ d^2
where k = proportionality constant
k = Fd^2
k = 5 * 9^2
k = 5*81 = 405
d = (K/F)^1/2
d = (405/3)^1/2
d = 11.62 =11.6
Answer:
11.62
Step-by-step explanation:
F is inversely proportional to d^2, so
[tex]F=\frac{k}{d^2}[/tex]
for some constant k. To find k plug in given values for F and d.
[tex]5=\frac{k}{9^2}\\5=\frac{k}{81}\\k=405[/tex]
Now you can find d for F = 3.
[tex]3=\frac{405}{d^2}\\\\3d^2=405\\\\d^2=135\\d=\sqrt{135}\approx 11.62[/tex]
Write an algebraic expression for the following:
5 less than twice a number
5 less would be -5
twice a number would be *2
so the expression would be
2x - 5
Answer:
2x - 5
Step-by-step explanation:
let assume the number is x:
Therefore 2x - 5
The relationship between the length and weight of certain sea turtles can be approximated by the equation L = 0,55 W,
where L is the length in feet and W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?
Answer:
4.55 pounds
Step-by-step explanation:
From the above question , we are told that:
The relationship between the length and weight of certain sea turtles can be approximated by the equation
L = 0.55 W,
where
L is the length in feet
W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?
L = 2.5 feet
Hence,
2.5 = 0.55W
W = 2.5/0.55
W = 4.5454545455 pounds
Approximately, weight of the sea turtle in pounds = 4.55 pounds

c. 3(35)+7=112 cm
liner equations please help with answer!
Answer:
n = - [tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n
Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions
4(1 + n) = - 3n ← distribute left side
4 + 4n = - 3n ( add 3n to both sides )
4 + 7n = 0 ( subtract 4 from both sides )
7n = - 4 ( divide both sides by 7 )
n = - [tex]\frac{4}{7}[/tex]
Find the values of x, y, and z
Mark estimated that he would spend $300 of his paycheck on seven items that cost $50 each. Why is this not reasonable?
A. It is not reasonable because seven items could not all cost $50.
B. It is not reasonable because seven items at $50 each, would cost a total of $350.
C. It is not reasonable because seven items at $50 each would only cost $420.
D. It is not reasonable because he would have too much money left over.

Solve for x
[tex]3x = 27[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} = \frac{27}{3}[/tex][tex]x = \frac{27}{3}[/tex]

Answer:
(a) 0.6
(b) 0.4
Step-by-step explanation:
If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made [tex]9+6=15[/tex] shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
[tex]P([/tex]making a shot[tex])=\frac{9}{15}=\frac{3}{5}=0.6[/tex]
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.
[tex]P([/tex]making a shot[tex])+P([/tex]missing a shot) [tex]=1[/tex]
[tex]P([/tex]missing a shot[tex])=1-P([/tex]making a shot[tex])[/tex]
[tex]P([/tex]missing a shot[tex])=1-0.6=0.4[/tex]
QED
Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magnitude of the resultant vector. Pls help :( cant afford to fail
Answer:
The magnitude of the resultant force is: 27.40 pounds
Step-by-step explanation:
Given
[tex]F_1 = 45[/tex]
[tex]F_2 = 50[/tex]
[tex]\theta = 33[/tex]
Required
The magnitude of the resultant vector
To do this, we apply cosine formula
[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]
This gives:
[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]
[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]
[tex]R^2 = 2025+ 2500 - 3774.15[/tex]
[tex]R^2 = 750.85[/tex]
Take square roots of both sides
[tex]R = \sqrt{750.85\\[/tex]
[tex]R = 27.40[/tex]

Answer:
about 7.3 units
Step-by-step explanation:
to find the answer you do Pythagorean theorem
so you have (-9, -4) and (-2, -6)
you do X1-X2 and Y1-Y2
so -4-(6)=2
and -9-(-2)= -7
now you do a^2 + b^2 = C^2
so 2^2 + -7^2 = C^2
which is 4 + 49= C^2
53=C^2
√53=7.3
so 7.3 units :)
What is the domain of the function Y = tan(x/8)?
Oall real numbers except 4pi+4npi where n is any integer
Oall real numbers except 4pi+8npi where n any integer
Oall real numbers except 8pi+4npi, where n is any integer
Oall real numbers except 8pi+8npi, where n is any integer
Answer:
B) all real numbers expect 4pi+8pi where n is any integer
Step-by-step explanation:
The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.
What is the domain of a function?The domain is the set that contains all possible input values for the function.
Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
π/2 + nπ
Hence, let a composite tangent function , the domain is given by:
f(x) does not equal to π/2 + nπ
we have that , hence the domain is:
all real numbers except 4π+8nπ
All real numbers except 4π+8nπ, where n is any integer.

Rewrite the equation of the line in slope intercept form.
4x−8y=32
Answer:
y=1/2x-4
Step-by-step explanation:
subtract 4x from the left side and the right side. It becomes:
-8y=-4x+32
