Answer:
x= 37.5°
Step-by-step explanation:
∠CBD
= 180° -75° (adj. ∠s on a str. line)
= 105°
∠BCD= ∠BDC (base ∠s of isos. △BCD)
∠BCD= x
∠BCD +∠BDC +∠CBD= 180° (∠ sum of △BCD)
x +x +105°= 180°
2x= 180° -105°
2x= 75°
x= 37.5°
Alternative working:
∠BDA= (180° -75°) ÷2 (base ∠s of isos. △ABD)
∠BDA= 52.5°
∠BDA +∠BDC= 90°
52.5° +x= 90°
x= 90° -52.5°
x= 37.5°

m∠2 = _°
m∠4 = _°
Answers
Answer:
Angle 2 = Angle 4 = 76
Step-by-step explanation:
Here, we want to get the measures of angle 2 and angle 4
From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)
The reason for this is because both angles are same side interior angles
Thus,
angle 2 + angle 5 = 180
angle 2 = 180 - angle 5
angle 2 = 180 -104
angle 2 = 76
Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles
Thus, angle 2 = angle 4 = 76
Shiva uses 8.2 pints of blue paint and white paint to paint her bedroom walls. 3/4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answers
Answer: 2.05 pints
Step-by-step explanation:
Shiva used 8.2 pints in total to paint the bedroom.
3/4 of this was blue paint which means that the remaining 1/4 is white paint.
Pints of white paint used:
= Proportion of white paint * Total pints used
= 1/4 * 8.2
= 2.05 pints

The bacteria in a culture double every day. Which function can be used to find the number of bacteria n after d days if there are initially 75 bacteria?
On=2(75)
O n = 75(g)
On = 75(2)
On= (75)"
Answers
Answer:
n = 75(2)^d
Step-by-step explanation:
Mathematically, we have the general form of an exponential equation as follows;
y = I(1 + r)^x
where I is the initial value
r is the rate percentage
x is the number of time
From the question, the bacteria population doubles
This mean it increases by 100%
100% = 1
add this to the initial 1, and we have 2
Replace I with the number 75
And d represents the days
so we have;
n = 75(2)^d

Mike 24 coins in nices and dimes they are valued at $2.05. how many DIMES does he have?
Answers
Answer: He has 8 dimes
Step-by-step explanation:
Answer:
17 dimes
7 nickels
Step-by-step explanation:
n = number of nickels
d = number of dimes
0.10d + 0.05n = 2.05
n + d = 24, n = 24 - d
substitute for n:
0.10d + 0.05(24 - d) = 2.05
simplify:
0.10d + 1.20 - 0.05d = 2.05
0.05d = 0.85
d = 17
n = 24-17 = 7
