510
B
A
h
Answer:
39°
Step-by-step explanation:
Angle ABD and angle CBD are complementary angles which means they complete each other to 90°
so if CBD is 51 then ABD is 90 - 51 = 39°
Can someone help me answer this?
Answer:
x = 40 , y = 70
Step-by-step explanation:
y = 70°
x° = 180° - 2 × 70° = 40°

the area of a trapezium is 594 sq. cm. The lengths of its parallel sides are in the ratio 4 : 5. The height of the trapezium is 12 cm. Find the lengths of the parallel sides.
Answer:
1st side=44 cm, 2nd side= 55cm
Step-by-step explanation:
let a = '4x' , b = '5x'
h= 12cm
Area of trapezium=1/2*(a+b)h
area=594=1/2*9x*12
594*2/12=9x
594/6=9x
99=9x
99/9=11=x
therefore, 4x=4*11=44cm
&5x=5*11=55cm

if 5 goldfish cost $6.45 what is the cost of 8 goldfish
Answer:
Step-by-step explanation:
Cost of one fish = 6.45 ÷ 5 = 1.29
Cost of 8 fish= 1.29 x 8 = 10.32
Answer:
$10.32 is the cost of 8 golddfish
Step-by-step explanation:
First, we'll find the cost for one goldfish and then we can multiply by 8 to find the cost of 8 goldfish.
so we divide by 5, then times by 8
6.45/5 = 1.29
1.29 * 8 = 10.32
-1 + -4 I also need a example for it, thank you everyone for the help.
Answer:
-5
Step-by-step explanation:
Nothing cancels out so all you have to do is add the two numbers but keep the sum negative to get -5
Example:(?)
Jeff had -1 points on brainly. He lost 4 more points. How many points does he have now?
Answer. -5
Step-by-step explanation:
-1+-4. so here we multiple the signs(+×-)= -. that's why I came up with the answer -5 and when multipling signs please be kin enough to multiple. so here the multiplication of the signs (+×+)=+, (-×-)=+ please
What best describes movement of particles in a solid
Answer:The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are moving = vibrating in place.
Answer:
the movement of particles within a solid is normally slower, do to the particles being tighter together than the other classifications.

Answer: C=2
I know it seems difficult but it’s not as bad as it looks.
Step-by-step explanation:
First you add 7 to both sides of the equation as shown:
3c-7+7=-c+1+7
Then you simplify giving you the equation 3c=-c+8
Then you add C to both sides of the equation: 3c+c=-c+8+c
Then you combine like terms giving you the equation of 4c=8
After that you divide both numbers by 4 giving you the fraction of 8/4 otherwise know as 2. Hope this helps, best of luck.

When you are tryinf to find the slope you have to subtract from both sides and devide the number.
Answer:
Slope of equation is: m= -5/9
Option A is correct.
Step-by-step explanation:
We are given the equation: 125x+225y=6000
We need to find the slope of the equation. The slope can be found if we arrange the equation in slope-intercept form i.e y=mx+b where m is slope.
So, rewriting given equation in slope intercept form:
[tex]125x+225y=6000\\225y=-125x+6000\\\frac{225y}{225} =\frac{-125}{225}x+ \frac{6000}{225}\\y= \frac{-5}{9}x+ \frac{80}{3}[/tex]
Now comparing the equation with slope-intercept form i.e y=mx+b we get the value of slope i.e m= -5/9
So, Slope of equation is: m= -5/9
Option A is correct.

Find all solutions to the equation.
7 sin^2 x - 14 sin x + 2 = -5
Answer:
{-π/2, π/2}
Step-by-step explanation:
Rewrite this as:
7sin^2 x - 14sin x + 7 = 0. Reduce this result by dividing all terms by 7:
sin^2 x - 2sin x + 1
Temporarily replace "sin x" with y:
y^2 - 2y + 1 = 0
Solve this through factoring: (y - 1)^2 = 0, or y - 1 = ± 0, or y = ±1
Recalling that y = sin x, we write
sin x = ±1, whose solutions are sin x = 1 and sin x = -1
The solution of sin x = 1 is π/2 and that of sin x = -1 is -π/2
and so the solution set is {-π/2, π/2}

Step-by-step explanation:
A dentist sees patients each day to clean their teeth. The function g(x) represents the number of teeth cleaned, where x is the number of people who saw the dentist. Does a possible solution of (20, 20) make sense for this function? Explain your answer.
Yes. The input and output are both possible.
No. The input is not possible.
No. The output is not possible.
No. Neither the input nor output is possible.
Answer:
A.) Yes. The input and output are both possible.
Step-by-step explanation:
In this problem, a dentist sees patients each day to clean their teeth. So we represent this function as g(x) where:
x: Represents the number of people who saw the dentist.
g(x): Represents the number of teeth cleaned.
So we are given a point that is solution to our function, but what does this point represent? This tells us that the dentist saw 20 patients and cleaned 20 teeth. For example, a volunteer dentist can see more people than a common dentist and it is likely that that volunteer person sees fewer teeth. However, it's very difficult that that dentist finds 20 people with an only tooth each. So this situation is possible, but not realistic in the real world.
Answer:
Yes. The input and output are both possible.
In this problem, a dentist sees patients each day to clean their teeth. So we represent this function as g(x) where:

So we are given a point that is solution to our function, which is but what does this point represent? This tells us that the dentist saw 20 patients and cleaned 20 teeth, that is, he cleaned an only teeth per patient. So this will make sense under the conditions that make it possible, for example, a volunteer dentist can see more people than a common dentist and it is likely that that volunteer person sees fewer teeth. However, it's very difficult that that dentist finds 20 people with an only tooth each. So this situation is possible, but not realistic in the real world.

Tracey paid $195 for an item that was originally priced at $450. What percent of the original price did Tracey pay?
Answer:
50
Step-by-step explanation:
Answer:
About 43%.
Step-by-step explanation:
Well... 195/450 = x/100
100 times 195 = 450x
19500 = 450x
19500/450 = 450x/450
= 43.3% ( the 3 after the decimal point is repeated, but I rounded to the nearest percent).
I hope this helps.
Which equation can be used to find the measure of the angles below if line a is parallel to line b?
A. 5x - 54 + 3x + 16 = 180
B. 3x +16 = 180
C. 5x - 54 = 3x + 16
Answer:
C. 5x - 54 = 3x + 16
Step-by-step explanation:
These angles are alternate interior angles and their measurement is same
5x - 54 = 3x + 16
5x - 3x = 16 + 54
2x = 70 divide both sides by 2
x = 35
