Answer:
(7, 3.5)
Step-by-step explanation:
find the distances between the x and y
9 and 5 are 4 apart, and 2 and 5 are 3 apart
divide those distances by 2
4/2 = 2, 3/2 = 1.5
add those distances to the smaller of the x and y
5 + 2 = 7, 2 + 1.5 = 3.5
those two numbers are the midpoint (7, 3.5)
Write f(x) in terms of sin(x) and cos(x).
Answer:
f(x) = cos(x)
Step-by-step explanation:
Given the expression
[tex]tan(x)csc(c) = \frac{1}{f(x)}[/tex]
Recall that;
[tex]tan(x) = \frac{sin(x)}{cos(x)} \\csc(x) = \frac{1}{sin(x)} \\[/tex]
Substitute into the given expression
[tex]tan(x)csc(c) = \frac{1}{f(x)}\\\frac{sin(x)}{cos(x)} \frac{1}{sin(x)} = \frac{1}{f(x)}\\\frac{1}{cos(x)} = \frac{1}{f(x)}[/tex]
Cross multiply
[tex]cos(x) = f(x)\\Swap\\f(x) = cos(x)[/tex]

There are 192 cubes. The length is 6 and the width is 4. What is the height?
Answer:
Height = 8
Step-by-step explanation:
Volume = Length x width x height
192 = 6 x 4 x H
192 = 24 x H
192/24 = H
8 = H
Height = 8

Answer:
c reflexive property
if you look at it it's reflecting
=============================================================
Explanation:
For statement 1, we'll have angle O congruent to angle M. This is visually given by the angle arcs that are the same.
For statement 2, we'll have segment OL congruent to segment LM. This is also given because of the tickmarks on the segments to show they are the same length.
In statement 3, angle KLO is congruent to angle MLN. The reason for this is they are vertical angles. So if your teacher was asking about what goes for reason 3, then you would be correct in selecting choice A.
The actual answer is choice B) ASA because we have two pairs of congruent angles (refer to statements 1 and 3 mentioned earlier); between those angles for each triangle we have a pair of congruent segments (refer to statement 2). So that's why we go for ASA. As you can probably guess, "A" stands for "angle" and "S" stands for "side". The order matters. The side must be between the angles in question. This means AAS is slightly different than ASA.
Side note: The reflexive property is the idea that any segment or angle is congruent to itself. It's not used at all here, but it's useful in other situations.
Another side note: CPCTC stands for "corresponding parts of congruent triangles are congruent". It basically means that if two triangles are congruent, then the pieces that match up together are congruent as well.

the ratio of the age of father and his son is 9:4. if the son is 24 years old find the age of father
Answer:
The father is 54 years old
Step-by-step explanation:
Well from the ratio 9:4
We know the son is 24
we can divide 24/4 to get 6
now we know we have to multiply by 6 on each side of the ratio to get the final result
54:24
Answer:
54 years old
Step-by-step explanation:
Because the son is 24 years old, we know that that is 6 times the '4' in the ratio 9:4 therefore if we do 6*9=54 that is the age of his father!

Step-by-step explanation:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 421 gram setting. It is believed that the machine is underfilling the bags. A 26 bag sample had a mean of 413 grams with a standard deviation of 24. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
Answer:
The p-value is approximately 0.0508
Step-by-step explanation:
The given parameters are;
The expected mass of banana chips bag filled by the machine, μ = 421 gams
The number of bags in the sample of bags filled by the machine, n = 26 bags
The mean mass of the bags in the sample, [tex]\overline x[/tex] = 413 grams
The standard deviation of the mass in the bags, s = 24 grams
The level of significance, α = 0.02
The null hypothesis, H₀; μ = 421 grams
The alternative hypothesis, Hₐ; μ < 421 grams
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{413-421 }{\dfrac{24}{\sqrt{26}}} \approx -1.6996731712[/tex]
The t-value = -1.6996731712
The degrees of freedom df = n - 1 = 26 - 1 = 25
From an online source, we get the critical-t = 2.166587
The p-value is obtained using an online source as p(t ≤ -1.6996731712) = 0.0508
From the p-value table, we get
0.05 < p < 0.1
Melanie is going to invest $45,000 and leave it in an account for 20 years. Assuming
the interest is compounded continuously, what interest rate, to the nearest
hundredth of a percent, would be required in order for Melanie to end up with
$142,000?
Answer:
Rate of interest r = 5.20% (Approx.)
Step-by-step explanation:
Given:
Amount invested p = $45,000
Final amount A = $142,000
Number of year = 20
Find:
Rate of interest r
Computation:
A = p[1+r]ⁿ
142,000 = 45,000[1+r]²⁰
3.1556 = [1+r]²⁰
r = 5.194
Rate of interest r = 5.20% (Approx.)

Answer:
9. B. 32 millimeters
10. C. 7 inches
11. C. 56.24 millimeters
13. B. 14.13 square feet
Step-by-step explanation:
9. Radius of a circle or any circular shape = ½ of its diameter
Diameter of the disk = 64 millimeters
Radius of the disk = ½(64) = 32 millimeters
10. Width of the cooler = 6 in.
Length = 8 in.
Volume = 336 in.³
Height = ?
Formula for volume of a rectangular prism = L*W*H
Plug in the values
336 = 8*6*H
336 = 48*H
Divide both sides by 48
336/48 = H
H = 7 inches
11. A dime has a circular shape
The circumference of the dime = circumference of a circle = πd
Where,
d = 17.91 millimeters
π = 3.14
Plug in the values
C = 3.14 × 17.91 = 56.2374
≈ 56.24 millimeters (nearest hundredth)
12. Area of the top of the desk = area of semicircle = ½ × πr²
Where,
r = ½(6) = 3 ft
π = 3.14
Plug in the values
Area = ½ × 3.14 × 3² = ½ × 3.14 × 9
Area = 14.13 square feet
Find each angle measure
Answer:
angle 1 = 63°
angle 2 = 117°
angle 3 = 63°
Step-by-step explanation:
angle 2 = 117° (vert.opp.angles)
angle 1 = angle 3 (vert.opp.angles)
angle 1 + angle 2 + angle 3 + 117° = 360°
angle 1 + 117° + angle 3 + 117° = 360°
angle 1 + angle 3 = 360° - 117° - 117°
angle 1 + angle 3 = 126°
angle 1 = 63°
angle 3 = 63°

Answer:
(2,4)
Step-by-step explanation:
The coordinate of A is (2,-4) currently. If we reflect that point over the x-axis, the y coordinate will change into the opposite sign. Because the y coordinate is -4, it will change to - (-4) = 4. Therefore, the coordinate of A' would be (2,4).
express y as a function of x.

How do you convert a fraction or decimal to a percent?
Answer:
a
Step-by-step explanation:
Answer:
To convert a decimal to a percent, multiply it by 100 (move the decimal place two digits to the right) and add the "%" sign.
A fraction must be converted into a decimal first by dividing the denominator into the numerator, then converting that answer to a percent like above.

a bag contains 1 red beads,2 yellow beads,2 green beads and 1 blue beads
a bead is chosen at random
a)what is probability that it is green ?
b)what probability that it is green or yellow
Answer:
a) 2/6 b) 4/6
Step-by-step explanation:
You add the amount of beads: 1+2+2+1= 6
And take the amount of green beads and put it over the total amount so 2/6
For b you do the same but add the green and yellow beads and put that over the total amount 4/6
Answer:
Step-by-step explanation:
a) 2/6 = 1/3
b) green or yellow = (2/6 x 1/5) + (2/6 x 1/5) = 1/15 x 1/15 = 1/225
