What is the sign of -xy?
Answer:
Positive
Step-by-step explanation:
Since x > 0 = x is positive
Since y < 0 = y is negative
Product of positive and negative number is negative.
Therefore,
xy = - xy
- (xy) = -( -xy)
- (xy) = xy [since product of negative and negative is positive]
100 students are interviewed to see which of biology, chemistry or physics they prefer.57 of the students are girls. 34 of the girls like biology best.27 of the boys prefer physics.20 out of the 28 who prefer chemistry are girls.What percentage of the students prefer biology?
Answer:
42%
Step-by-step explanation:
I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:
(34+8)÷100×100 = 42%

Find m∠EGF. please help!
Answer:
[tex] \large{ \tt{❃ \: EXPLANATION}} : [/tex]
We're provided - ∠AGB = 30° , ∠ DGC = 50° and ∠ EGF = 2x. We're asked to find out m ∠ EGF.Note that ∠ AGB , ∠ BGC and ∠ DGC form a straight line which means that their sum is equal to 180°.When two lines intersect , the angles formed opposite to each other are called verticall opposite angles. Vertically opposite angle are always equal to each other.[tex] \large{ \tt{❈ \: SOLUTION}} : [/tex]
Re-read the second point which I have mentioned above. Now , Set up an equation and solve for ∠ BGC .[tex] \large{ \tt{{ ♡ \: \angle \: AGB + \angle \: BGC \: + \angle \: DGC = 180 \degree}}}[/tex] [ Sum of angle in a straight line ]
[tex] \large{ \tt{⟶ \: 30 \degree + m \angle \:BGC \: + \: 50 \degree = 180 \degree}}[/tex]
[tex] \large{ \tt{⟶ \: m \angle \: BGC + 80 \degree = 180 \degree}}[/tex]
[tex] \large{ \tt{⟶ \: m \angle \:BGC= 180 \degree - 80 \degree}}[/tex]
[tex] \large {\tt{⟶ \: m \angle \: BGC = 100 \degree}}[/tex]
Hence , m ∠ BGC = 100°. Now , Re-read the third point which I have mentioned above and set up an equation and solve for x.[tex] \large{ \tt{❊ \: 2x = 100 \degree}}[/tex] [ being vertically opposite angles ]
[tex] \large{ \tt{⇢\frac{2x}{2} = \frac{100 \degree}{2} }}[/tex]
[tex] \large{ \tt{⇢ \: x = 50 \degree}}[/tex]
The value of x is 50°. Now :[tex] \large{ \tt{❁ \: REPLACING \: VALUE : }}[/tex]
[tex] \large{ \tt{ ➝ \: \angle \: EGF = 2x \degree = 2 \times 50 = \boxed{ \tt{100 \degree}}}}[/tex]
[tex] \boxed{ \boxed{ \large{ \tt{☄ \: OUR \: FINAL \: ANSWER : \boxed{ \underline{100 \degree}}}}}}[/tex]

Answer:
100°
Step-by-step explanation:
Since ∠AD are 180°, and each side is the same,
180°-30°-50°=100°
Answer please giving out my last points
∠DGC and ∠CGB are _ angles.
Answer: Adjacent
Step-by-step explanation:
Complementary means angles summing upto 90°
Vertical means opposite angles
Supplementary means angles summing upto 180°
So, the resonable answer will be adjacent since both the angles are beside each other.

what is an expression for the length of the pool? step by step
Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1

==========================================================
Explanation:
At first the car isn't moving at all. This is at time 0. So this means the graph starts at the origin (0,0). Based on this alone, the answer is either choice B or choice C.
We can rule out choice C because the rates of change won't be constant to give those sharp straight lines. Instead, we have a gradual shift in speeds as the roller coaster progresses. So we'll have more of a curved shape as choice B shows.
Note that each time the car is going downhill, the speed goes up. On the flip side, as the car goes uphill, the speed goes down. So the direction of movement runs counter to the speed graph direction (one goes up, the other goes down).
A person takes part in a medical trial that tests the effect of a medicine on a disease. Half the people are given medicine and the other half are given a sugar pill, which has no effect on the disease. The medicine has a 60% chance of curing someone. But, people who do not get the medicine still have a 10% chance of getting well. There are 85 people in the trial and they all have the disease. Talwar takes part in the trial, but we do not know whether he got the medicine or the sugar pill. Draw a tree diagram of all the possible cases. What is the probability that Talwar gets cured?
Answer:
Talwar has 35% chance of getting cured
When r+s=13 and 2t+s=13 , what is the value of t?
Answer:
t = 5
Step-by-step explanation:
by using guess and check, we can plug in the numbers 5 into t, 3 into s, and 10 into r.
if t = 5, then r must mean twice that number meaning it is 10.
the remainder would be s which means it is 3.
r+s=13 into 10 + 3 = 13
2t+s=13 into 2(5) + 3 = 13

What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
What is the shape that the question below
Answer:
Answer: D
Step-by-step explanation:
Let's just go through it.
No parallel sides A B C (if you believe the diagram) D F
Not regular (and no parallel sides) (if you believe the diagram) B C D F
No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front of the mirror. C D F
Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360
That lets out everybody but D.
Answer: D
Step-by-step explanation:
1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.
2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.
3. B can be ruled out now.
4. The only one with a reflex angle (greater than 180 degrees) is D.

The first rule is subtract 6 starting from 48. The second rule is subtract 3 starting from 30. What is the second ordered pair using the terms in each sequence? (42, 27) (36, 24) (48, 30) (30, 21)
Answer:
(42,48)?
Step-by-step explanation:
Answer:
(42, 27)
Step-by-step explanation:
The first rule is to do [tex]48-6[/tex], so this would be the x- axis.
The second rule is to do [tex]30-3[/tex], so this would be the y-axis.
The first ordered pair would be (48, 30), then the second ordered pair would be (42, 27).
write 1 1/2 and 2 1/4 on the number line below.
Answer:
So lets convert the fractions to improper:
3/2 and 9/4
And for it to be easier to plot, make them decimals (divide):
1.5 and 2.25
The step here is 0.125 (1/8 (the amount of lines between a number))
Plot:
1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line..
Lets convert the fractions to improper:
1 1/2 = 3/2 = 1.5.
2 1/4 = 9/4 = 2.25.
3/2 and 9/4
And for it to be easier to plot, make them decimals (divide):
1.5 and 2.25
Therefore, 1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line.
