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.
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

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

find x and y intercept
Answers
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)

Calculate the area of the annulus which has an external diameter of 25cm and an internal diameter of 15cm
Answers
Answer:
314.159 square cm
Step-by-step explanation:
Area of an annulus with external radius r1 and internal radius r2 is given by
π(r1² - r2²)
radius = half diameter
r1 = 25/2 = 12.5 cm
r2 = 15/2 = 7.5 cm
Area of annulus
= π(12.5² - 7.5²)
= 314.159 square cm
The correct answer is 314.159 square cm
