Answer:
AC = 12.5 cm
Step-by-step explanation:
use cosine law c^2 = a^2 + b^2 − 2ab cos(C)
c^2 = 6^2 + 10^2 - 2(6)(10)(cosin100)
c^2 = 156.84
c= √156.84
c= 12.5 cm
The cosine rule is used when we are given either three sides or two sides and the included angle.
Answer:
11.66 which is approximately 12
Step-by-step explanation:
by using Pythagoras method
\(a^{2}+b^{2}=c^{2} because c is the hypotenuse\)
\(6^{2}+10^{2}=c^{2}\)
\(36+100=c^{2}\)
\(136=c^{2}\)
\(\sqrt{136}=\sqrt{c}\)
\(c=11.66\)

If we are given the equation of a line in this format:
y=mx+b
then it is quite simple to find the gradient and y-intercept.
In the format:
y=mx+b
the m represents the gradient (slope) and b represents the y-interpcept.
1) y=2x+3
gradient= 2
y-intercept= 3
2) y=x-5
gradient= 1
y-intercept= -5
3) y=-2x-4
gradient= -2
y-intercept= -4
4) y=5-x
gradient= -1
y-intercept= 5
5) y=3x+8

Answers
Answer:
Step-by-step explanation:
You could do negative numbers because no positive number is less than 0, as you know.
So, it would have to be a negative one because they are to the left of zero on a number line, meaning less than. A positive number on a number line is usually to the right of zero, meaning more than.
For instance, x could equal -1 and y could equal -4.
It would be in Quadrant 3.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Some students are preparing to drive from Austin, Texas to Orlando, Florida for Spring Break. They look on a map that shows 1/2 inch equaling 100 miles. The distance on the map is about 5 1/2 inches. About how many miles apart are the two cities?
Answers
Answer:550
Step-by-step explanation:
1 inch = 100 miles
5*100 = 500
1/2 * 100 = 50
500+50 = 550
So the cities are 550 miles apart
Answer: 550
Step-by-step explanation:
1 inch = 100 miles
5*100 = 500
1/2 * 100 = 50
500+50 = 550
So the cities are 550 miles apart
In trapezoid ABCD, AB ∥ CD , m∠A=90°, AD=8 in, DC=9 in, CB=10 in, and ∠B is acute. Find DB.
Answers
Answer:
the length of DB is 17 in
Step-by-step explanation:
Consider the sketch attached.
We will draw an imaginary line from point C to met line AB at point E.
A right-angled triangle will now be formed between points CBE.
The dimensions of the right-angled triangle will be:
CB = 10 in
CE= 8 in
EB = unknown
We will now proceed to find out the length of side EB using the Pythagoras' theorem.
\(EB =\sqrt{CB^2 -CE^2} \\EB =\sqrt{10^2 -8^2} \\EB = 6 in\)
From the shape, we can find out that another right-angled triangle is made between points DAB.
The dimensions of the triangle are:
DA= 8in
AB = 9 in + 6 in = 15 in
DB = unknown.
We will now proceed to find out the length of side DB using the Pythagoras' theorem.
\(DB =\sqrt{AD^2 +AB^2} \\DB =\sqrt{8^2 +15^2} \\DB = 17 in\)
Therefore, the length of DB is 17 in

What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction
Answers
Answer:
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
Step-by-step explanation:
1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625
The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."
The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.
In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."
Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.
Mathematical representation: \(\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}\)

how to check : 3x+5=11
Answers
Answer:
There are two ways to check if 3x+5=11 is true:
Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.
3x = 6
Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.
x = 2
You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
