Find the length of DC
**PLS**
Answer: 30.43
Step-by-step explanation: The smaller triangle has an angle of 54°. The hypothenus is 20, so we're looking for the opposite using SOHCAHTOA
Sin x = opp/hyp
Sin 54 =opp/ 20
Opp= sin54 ×20
Opp= 16.18
Therefore, BD is 16.18
In the bigger triangle, with taking the angle 28° we have DC to be the adjacent.
Tan 28° = 16.18/adj
Adj = 16.18/tan 28°
Adj = 30.43
DC = 30.43
A filter for a fish tank can filter 120 gallons per hour. How many gallons per minute is
that?
Theres 60 mins. in a hour, so just do 120/60 which is 2.
so, 2 gallons/minute
Answer:
The answer is 2 gallons per minute.
Step-by-step explanation:
The way I found the answer was there is 60 minutes in a hour and in a hour it can filter 120 gallons so if you do 120 divided by 60 that gives you 2. So the answer is 2 gallons per minute.

How useful is the slope of a line in the equation?
I WILL MARK IT BRAINLIEST IF YOU ANSWER IT PROPERLY<3
The slope of the line is really important, because first, it just wouldn't be a proper equation and second, "Slope shows both steepness and direction." If the slope isn't there, then we wouldn't know whether the equation is positive or negative.
So sorry if that's incorrect...

A stack of books weights 3.5 kilograms.About how many pounds is this.(Note : one pound is about 0.45 kilograms)
Answer:
7.8 pounds
Step-by-step explanation:
The relation between pounds and kilograms is proportional:
[tex]\dfrac{\text{books}}{3.5\text{ kg}}=\dfrac{1\text{ lb}}{0.45\text{ kg}}\qquad\text{pounds to kg proportion}\\\\\text{books}=\dfrac{(3.5\text{ kg})(1\text{ lb})}{0.45\text{ kg}}=\dfrac{3.5}{0.45}\text{ lb}\qquad\text{multiply by 3.5 kg}\\\\\boxed{\text{books}\approx7.8\text{ lb}}[/tex]
The stack of books weighs about 7.8 pounds.

Answer:
K12 Answer
Step-by-step explanation:
The correct answer would be an option (A) which is the location of the endpoint to plot the inequality on the number line.
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.
Any directed number's location can be determined using a number line. There are positive and negative axes in it.
We have been given that inequality on the number line.
⇒ w – 0.7 > -1.1
⇒ w > -1.1 + 0.7
⇒ w > -0.4
⇒ w < 0.4
Therefore, the correct answer would be option (A) which is the location of the endpoint to plot the inequality on the number line.

Four eight-ounce glasses of juice and three eight-ounce glasses of orange juice contain a total of 632.1 milligrams of vitamin C. How much vitamin C is in an eight ounce glass of each type of juice?
Answer:
8 ounces has = 2661.81685milligrams vitamin C in apple juice = 2.66181685 grams and 8 ounces has = 3549.60145milligrams vitamin C in orange juice =3.54960145 grams
Step-by-step explanation: 28.3495231 g = 1 ounce 28349.5231 mg = 1 ounce Therefore simultaneous equations can be done once converted What we will see is it is easier if back to ounces once you learn how to do scientific notation scientific notation convert as 1 ounce = 0.00632462mg = (6.32462 *10^-3) So if you are not confident with scientific notation you can instead convert an ounce of juice to mg and multiply by 1/8 = 28349.5231 * 1/8 = 3543.69039 a and 3543.69039 o to start a simultaneous equation 3543.69039 a + 3543.69039 o = 179.3 and 4/8 = 4 * 3543.69039 = 14174.7616o ( + 3543.69039 * 3 (of 3/8) ) =10631.0712a = 14174.7616o + 10631.0712a = 632.1 to cancel out 10631.0712a we have to make a = a or o=o Therefore 3543.69039 = o 3543.69039 * 4 will make all equal for equation 1 = 14174.7616a +14174.7616o = 179.3 *4 = 717.2 then subtract equation 2 as it is lower now 14174.7616a +14174.7616o = 179.3 *4 = 717.2 - 14174.7616a + 10631.0712o = 632.1 cancels out ( a) now to show 14174.7616o = 717.2 - 10631.0712o = 632.1 = 14174.7616 - 10631.0712= (3543.6904o = (717.2 -632.1) ) = 3543.6904o = 85.1 o = 3543.6904/85.1 o = 41.6414853milligrams and a = input for o showing original equation 14174.7616 (41.6414853) + 10631.0712a = 632.1 = 590258.127 + 10631.0712a = 632.1 = 10631.0712a = (632.1 - 590258.127) = a = -589626.027/ 10631.0712 = -55.4625226 a= - 55.6 and o =41.6 we then Check other SEQ 3543.69039 ( 41.6414853) (For apple juice (a)) + 3543.69039 o = 179.3 = 147564.531 a + 3543.69039 o = 179.3 = 3543.69039 o = 179.3 - 147564.531 (/3543.69039) = o = -41.5908882 so proves all is positive Check other SEQ 3543.69039 + 3543.69039 ( 41.6414853) = 179.3 is the same and correct to o= 41.5908882 and a =55.4625226 we just multiply these by 8 and 8 again to get 8 ounces 41.5908882 * 8 =332.727106* 8 =2661.81685 (same as (a*64) and o*8*8 = 55.4625226 * 8 =443.700181 * 8 =3549.60145 and we have our answer s vitamin C in apple juice = 2661.81685milligrams = 2.66181685 g and vitamin C in orange juice = =3549.60145milligrams = 3.54960145g
For a project, Gabrielle made a model of an Egyptian pyramid. The square base has a side length measuring 10 inches. The pyramid is 12 inches tall.
What is the surface area of the model?
240 square inches
260 square inches
340 square inches
360 square inches
The surface area of the Egyptian pyramid model is 340 square inches.
Option C is the correct answer.
What is a pyramid?A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.
The volume of a pyramid with a square base is given as:
Volume = 1/3 x base area x height
We have,
The base of the pyramid is a square with a side length of 10 inches.
And,
Area = 10 inches x 10 inches
= 100 square inches
The pyramid has four triangular faces, each with the same dimensions.
To find the area of one of these faces, we can use the formula for the area of a triangle:
Area = (1/2) x base x height
The base of each face is 10 inches since it is the same as the side length of the square base.
The height of each face is the height of the pyramid, which is 12 inches.
So the area of each triangular face.
= (1/2) x 10 inches x 12 inches
= 60 square inches
Since there are four triangular faces, the total area of all the triangular faces.
= 4 x 60 square inches
= 240 square inches
The total surface area of the model is the sum of the area of the base and the area of the four triangular faces.
= base area + triangular face area
= 100 square inches + 240 square inches
= 340 square inches
Thus,
The surface area of the Egyptian pyramid model is 340 square inches.

A car insurance company has determined that 7% of all drivers were involved in a car accident last year. Among the 19 drivers
living on one particular street, 4 were involved in a car accident last year. If 19 drivers are randomly selected, what is the
probability of getting 4 or more who were involved in a car accident last year? (Hint: use binomial probability).
Answer:
explanation below
Step-by-step explanation:
so in order for all 19 drivers to not be in a car accident the probability is
.93 ^ 14 which is around 0.362,
next for 18 of the drivers no accident its
.93^13 x .07 x 19 = around .518
for 17 drivers,
.93^12 x .07^2 x 171 = around .350
