Answer:

Solution = 24 mice

Step-by-step explanation:

The ratio of brown mice to white mice is 5:3 this means the number of brown to white mice has to double until there is 6 more brown mice than white mice.

For example:

5:3

10:6

15:9

15 + 9 = 24

Therefore, there are 24 mice at the store.

24 Mice

15+9=24

5:3

10:6

15:9

There's one triangle satisfying angle BCA = 60 degree, AB = 12 and AC = 10 shown below:
The only possible value of BC is a, as shown above. What is a?

Answers

Answer:

13.3

Step-by-step explanation:

draw a line from A to be perpendicular to line BC

which will cut a into 2 parts. call it a1, & a2

so now you have 2 right angle triangle - left side one with an angle known 60°, which means the top angle after the separation is 30° & something else, we don't care that part.

any right angle triangle with 30-60-90 ° has a property of shorter side = 1/2 of the long side. so right away we know a1= 5. and the perpendicular line = 5√3. this property you should memorize.

now solve a2. look at the triangle on the right.

because we know the perpendicular line is 5√3, and long side =12

so (a2)² = 12² - (5√3)² =144-75 =69

so a2 = 8.3

so a = a1+a2 = 5+8.3 =13.3

Answer:a = 13.31

find x and y intercept

Answers

X Intercept = (-6,0)
Y Intercept = (0,-8)

Answer:

x-intercept: (-6,0)

y-intercept: (0,-8)

Step-by-step explanation:

The x-intercept is when y = 0.

The y-intercept is when x = 0.

Each intercept can be solved with substitution in the standard form equation.

Given the re-arranged standard form equation is

-3y = 4x + 24

With a standard form equation being in the form:

Ax + By = C.

-3y = 4x + 24 →

-3y – 24 = 4x + 24 – 24 →

-3y – 24 = 4x →

-3y + 3y – 24 = 4x + 3y →

-24 = 4x + 3y →

4x + 3y = -24

x-intercept:

given y = 0

4x + 3(0) = -24 →

4x = 24 →

4x / 4 = -24 / 4 →

x = -6 →

(-6, 0)

y-intercept:

given x = 0

4(0) + 3y = -24 →

3y = -24 →

3y / 3 = -24 / 3 →

y = -8 →

(0, -8)

help me with the true/false statement pls

Answers

Answer: False, True, True, True.

Step-by-step explanation:

A : False, if you place the same parallelogram back to its original place, it wont change its size.

B : True, if the two sides are parallel originally, then it will most likely be parallel for the final product.

C : True, you can move the parallelogram back to its original state, and the two sides are equal to the final product.

D : True, just like B, if the original is the same length, chances are that the final product will be equal.

Answer:

Therefore, it made 42 candles.

Step-by-step explanation:

Volume of cylinder = 3.14 * r² * h = 3.14 * 2² * 6 = 3.14 * 24 = 75.36 in³

It made = 3165.12 in³/75.36 in³ = 42

A concrete pillar has the shape of a cylinder. It has a diameter of 6 meters and a height of 5 meters. If concrete costs $96 per cubic meter, how much did the concrete cost for the pillar?

question 1: add 30 + 30 = 60, then subtract 180 - 60 since all angles of a triangle add up to 180. 180 - 60 = 120 so x equals 120 degrees

question 2: take 40 + 90 = 130, then subtract 180 - 130 = 50. x = 50 degrees

question 3: the ratio 4:4:10 can be converted to angles of a triangle, 45, 45, 90. this means that angles F and G will equal 45 degrees, and angle H will equal 90 degrees

question 4: this is finding the coterminal angle to get the answer. we know that angle 1 is 42 degrees, so we want to subtract 90 - 42 to get 48. coterminal angles in an example like this need to add up to 180 degrees. so we subtract 180-48 to get 132 degrees. angle 2 = 132 degrees

question 5: using what we did last problem, we can take angle 4 and find the coterminal angle which is 180-74=106 degrees. we can then add angles 2 and 3 together (106+43) which gives us 149 degrees. subtract 180-149= 31. angle 1= 31 degrees and angle 2= 106 degrees

The measure of <1 is 31 degree and measure of <2 is 106 degree.

What is Exterior angle Property?

If a triangle side is created, the outside angle that results is equal to the product of the two opposite internal angles.

Given

m <4 = 74 and m<3 = 43

Using Exterior Angle Property

m<4 = m<3 + m<1

74 = 43 + m<1

m <1= 74-43

m <1= 31 degree

and, Using Angle Sum Property

<1+ <2 + <3 = 180

31 + <2 + 43 = 180

<2 = 106 degree
