How much is x? Round answer to the nearest tenth. Please help!!
Answer:
x is half of the volume of the triangle because it can definitely fit inside the other triangle which means it's half
Answer:
x = 13
Step-by-step explanation:
Use pythagorean theorem. So say a is the side that's unknown
13^2 + a^2 = 17^2
a = √120 or 2√30
now do the same for the other triangle
( 2√30)^2 + 7^2 = x^2
120 + 49 = x^2
169 = x^2
x = 13

sinA =
Answer: Cos A = 0.96, Tan A = 0.29 and Sin A = 0.28
Step-by-step explanation: The right angled triangle can be solved by applying the trigonometric ratios given a follows;
Sin A = opposite/hypotenuse
Cos A = adjacent/hypotenuse
Tan A = opposite/adjacent
In the triangle ABC, the side AB (25) is the hypotenuse [facing the right angle], the side CB (7) is the opposite [facing the reference angle A°] while the side AC (24) is the adjacent [line between the reference angle and the right angle].
Therefore, using angle A as the reference angle;
(a) Cos A = adjacent/hypotenuse
Cos A = AC/AB
Cos A = 24/25
Cos A = 0.96
(b) Tan A = opposite/adjacent
Tan A= CB/AC
Tan A = 7/24
Tan A = 0.29
(c) Sin A = opposite/hypotenuse
Sin A = CB/AB
Sin A = 7/25
Sin A = 0.28

gallon of fruit punch. She pours an equal amount into 8 glasses.
What fraction of a gallon fruit punch is in each glass?
Question:
Felicia makes ½ gallon of fruit punch. She pours an equal amount into 8 glasses.
What fraction of a gallon fruit punch is in each glass?
Answer:
The fraction of a gallon fruit punch is in each glass is 1/16
Step-by-step explanation:
Given
Size of fruit punch = ½ gallon
Number of glass = 8
Required
Fraction of a gallon fruit punch is in each glass?
To solve this question, the following assumption has to be made.
- The 8 glass cups are of equal sizes.
Having said that;
The interpretation of the question is that, the fruit is evenly distributed into the 8 glass cups.
Mathematically, the size of the fruit punch will be divided by the number of glass cups.
So, we have
Fraction = ½ ÷ 8 (convert ÷ to *)
Fraction = ½ * ⅛
Fraction = 1/16
Hence, the fraction of a gallon fruit punch is in each glass is 1/16
Final answer:
To find the fraction of a gallon of fruit punch in each glass, divide 1/2 gallon by 8. This results in each glass containing 1/16 of a gallon of fruit punch.
Explanation:
The student asked how to find the fraction of a gallon of fruit punch in each glass if Felicia makes ½ gallon of fruit punch and pours an equal amount into 8 glasses. To answer this question, you need to perform a division of the total amount by the number of glasses. Given that Felicia has ½ gallon, which is the same as 2/4, we can divide this by 8 to find the amount in each glass.
Step-by-step solution:
Start with the fraction of a gallon Felicia has: ½ gallon.
Convert ½ to fourths to make the division easier: ½ = 2/4 gallons.
Since there are 8 glasses, divide 2/4 by 8. This is done by multiplying the denominator by 8:
(2/4) × (1/8) = 2/32.
Simplify the fraction by dividing numerator and denominator by the common factor of 2: 2/32 = 1/16.
Therefore, each glass contains 1/16 of a gallon of fruit punch.

Answer:
The value of DC is 66.34.
Step-by-step explanation:
The triangles ABC and DCA are right angled triangles.
The straight line AC is a bisector for angles C and A.
The measure of ∠C is 30°.
Then the measure of angles BCA and ACD will be 15° each.
The measure of angle DAB is 150°.
Then the measure of angles DAC and BAC will be 75° each.
Now consider the right angled triangle ABC.
The measure of side AC is:
[tex]AC^{2}=AB^{2}+BC^{2}\\AC=\sqrt{AB^{2}+BC^{2}}\\=\sqrt{4^{2}+(10\sqrt{3})^{2}}\\=\sqrt{316}[/tex]
Consider the right angled triangle DCA.
The angle DAC measure 75°.
Using the trigonometric identities compute the value of Perpendicular DC as follows:
[tex]tan\ 75^{o}=\frac{DC}{\sqrt{316}}\\\\DC=3.732\times\sqrt{316}\\\\DC=66.34[/tex]
Thus, the value of DC is 66.34.

WORTH 100 POINTS PLEASE HELP ASAP!! Joshua charges $12.50 an hour for his tutoring services. He also charges the same rate for giving guitar lessons.
On Saturday, Joshua drove to Eric's house to tutor him. To compensate for his traveling, Joshua charged a flat amount of $4.50 in addition to his hourly rates. For Saturday's session, Joshua earned a total of $35.75.
On Sunday, Joshua gave Ben guitar lessons for 0.5 hour and tutored him for the remaining time. A flat rate for traveling was not charged. For Sunday's session, Joshua earned a total of $31.25.
Complete the sentences.
Joshua tutored Eric Ben.
Joshua earned more on Saturday than on Sunday.
Joshua tutored Eric on Saturday and Sunday to Ben. Joshua earned $4.50 more on Saturday than on Sunday.
Joshua tutored Eric on Saturday and Sunday to Ben.
On Saturday, Joshua charged $12.50 per hour for tutoring, and since he also charged the same rate for guitar lessons, the total earnings were based on the combined time spent on tutoring and guitar lessons.
He added a flat fee of $4.50 for traveling. With a total earning of $35.75, the equation can be set up as follows:
[tex]\[ \text{Total Earnings on Saturday} = (\text{Hourly Rate} \times \text{Total Hours}) + \text{Flat Traveling Fee} \][/tex]
[tex]\[ 35.75 = (12.50 \times \text{Total Hours}) + 4.50 \][/tex]
Solving for the total hours, we find that Joshua spent 2 hours tutoring and giving guitar lessons on Saturday.
On Sunday, Joshua spent 0.5 hours giving guitar lessons and the remaining time tutoring Ben. Without a flat rate for traveling, the total earnings on Sunday were $31.25. Joshua's hourly rate remains $12.50. The equation can be expressed as:
[tex]\[ \text{Total Earnings on Sunday} = (\text{Hourly Rate} \times \text{Total Hours}) \][/tex]
[tex]\[ 31.25 = (12.50 \times \text{Total Hours}) \][/tex]
Solving for the total hours, we find that Joshua spent 2.5 hours tutoring and giving guitar lessons on Sunday.
Therefore, Joshua tutored Eric for 2 hours and gave guitar lessons for the remaining time on Saturday. On Sunday, he gave guitar lessons for 0.5 hours and tutored Ben for 2.5 hours.
Joshua earned $4.50 more on Saturday than on Sunday.

For ABD x equals 18 and for DBC equals 54.
Answer:
ABD = 36
DBC = 54
Step-by-step explanation:
The three angles form a straight line so they add to 180
2x + 3x +90 = 180
Combine like terms
5x+90 =180
Subtract 90 from each side
5x+90-90=180-90
5x= 90
divide each side by 5
5x/5 = 90/5
x =18
ABD = 2x = 2*18 = 36
DBC = 3x = 3*18 =54

What is the median of the data shown below?
Answer:
72
Step-by-step explanation:
You need to add the two middle numbers then divide them by two.
Hope this helps.
Answer: 72
Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.
Notice that our data set is already written from least to greatest so all we have to do now is find the number that appears in the middle.
Notice however that there are two numbers in the middle.
When this happens, take the sum of the two numbers in the middle or add them together and then divide the sum of the numbers by 2.
So if we add 71 + 73, we get 144.
Now just divide 144 by 2 to get 72.
So the median of the data set shown here is 72.

A block of cheese has a volume of 187 cm3 and a mass of 140 g.
What is the density of the cheese in g/cm3 rounded to 2 decimal places?
Answer:
0.75 g/cm^3 to 2 decimal places.
Step-by-step explanation:
Density = mass / volume
= 140 / 182
= 0.7487 g/cm^3.
The density of the cheese is 0.75 [tex]g/cm^3[/tex].
The student has asked to calculate the density of a block of cheese with a given volume and mass. Density is defined as mass per unit volume and is calculated using the formula:
Density = Mass / Volume
To find the density of cheese:
Use the given mass of the cheese, which is 140 grams.
Divide the mass by the given volume of the cheese, which is 187 [tex]g/cm^3[/tex].
Perform the division to get the density in grams per cubic centimeter ( [tex]g/cm^3[/tex].)
The calculation is as follows:
Density = 140 g / 187 [tex]g/cm^3[/tex]= 0.7487 [tex]g/cm^3[/tex].
After rounding to two decimal places, the density of the cheese is 0.75 [tex]g/cm^3[/tex].
