Answer:
17/25
Step-by-step explanation:
The required total score for 100% mark is given as 25.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Let the x be the be score for 100% marks.
68% of x = 17
x = 17 / 68%
x = 25
Thus, the required total score for 100% mark is given as 25.

8х + 5у = -7
— 7х + бу = — 4
Answer: x = -0.2651 and y = -0.9759
Step-by-step explanation:
Solution by substitution method
8x+5y= -7
-7x+6y= -4 = 7x-6y=4
Suppose,
8x+5y=-7→(1)
7x-6y=4→(2)
Taking equation (1), we have
8x+5y= -7
⇒8x= -5y -7
⇒x= -5y-7 / 8 →(3)
Putting x= -5y-7 / 8
in equation (2), we get 7x-6y=4
7(-5y-7/8)-6y=4
⇒-35y-49-48y=32
⇒-83y-49=32
⇒-83y=32+49
⇒-83y=81
⇒y= 81 / -83
⇒y= -0.9759→(4)
Now, Putting y= -0.9759 in equation (3), we get
x= -5y-7
x= -5(-0.9759)-7/8
⇒x= 4.8795-7/8
⇒x= -2.1205/8
⇒x= -0.2651
∴x= -0.2651 and y = -0.9759

8p<-3
Answer:
Step-by-step explanation:
8p < -3
You must isolate P
In order to do this, you need to get rid of anything on that side.
P is being multiplied by 8, so you must do the inverse in order to get rid of it.
The opposite of multiplying is dividing, so divide BOTH sides by 8.
8p / 8 < -3 / 8
You are left with:
p < -3 / 8
That is the answer

5.) g(x) = -4x + 2. Find x when g(x) = 22.
I'm on a timed test and I wasn't able to study because of personal reasons
Answer:
x = -5
Step-by-step explanation:
If g(x) = 22 and g(x) = -4x + 2, then -4x + 2 = 22.
Isolate x.
-4x = 22 - 2
= -4x = 20
= x = 20 ÷ -4
= x = -5

7 meters
20 meters
33 meters
13 meters
Answer:
Let H be height of a cliff
h depth of the pond
Total distance traveled (S)= H+h
S=20+13
S=33m
Step-by-step explanation:
Answer:
33 meters is the total distance
Step-by-step explanation:
the distance between the two points is 33 it does not matter if the distance is off the cliff or underwater it's still 20+13=33
the giraffe is the worlds tallest land mammal. if the scale is 1/2 inch represents 5 feet . the giraffe is 20 feet tall . how many inches is the giraffe?
Answer:
The giraffe will be 2 inches
Step-by-step explanation:
If we know that if the scale is 1/2 inch to 5 feet we simply just have to divide the height of the giraffe by 5 feet and then multiply it by 1/2 inches. So we do...
20feet / 5 feet x 1/2 inches = 4 x 1/2inches = 2 inches

AC is the opposite side. BC is the adjacent side. Iliana AB is the hypotenuse. BC is the opposite side. AC is the adjacent side. Who is correct? Explain. Tomas is correct; AC is opposite ∠B and BC is adjacent to ∠B. Iliana is correct; BC is opposite ∠B and AC is adjacent to ∠B. Both are correct because both AC and BC are opposite ∠B. Neither is correct because neither AC nor BC is opposite ∠B.

Please help me I have to get it done by 8 am!!!
Answer:
x = 20
Step-by-step explanation:
Here, we want to get the value of x
To get the value of x, we need to know the kind of relationship that exists between the two given angles
Both angles lie on a straight line and that means they are supplementary
What this mean is that they add up to 180
(5x-7) + (3x + 27) = 180
5x -7 + 3x + 27 = 180
5x + 3x -7 + 27 = 180
8x + 20 = 180
8x = 180-20
8x = 160
x = 160/8
x = 20
Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white? *
Complete question :
Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. The box contains 72 chocolates altogether. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white?
Answer:
7 / 9
Step-by-step explanation:
Calculate the number of each type of chocolate :
Milk : plain : white = 4 : 3 : 2
Total ratio = (4 +3 +2) = 9
Milk = (4/9) * 72 = 32
Plain = (3/9) * 72 = 24
White = (2/9) * 72 = 16
Probability of picking a chocolate that is not white :
Number of non-white :
(plain + milk) = (24 + 32) = 56
Probability = (required outcome / Total possible outcomes)
P(not white chocolate) = (number of non-white / total number of chocolates)
= 56 / 72
= 7 / 9

Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile.
If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now?
Select all that apply.
Answer:
The correct options are;
A. [tex]-\dfrac{8}{3} \ miles[/tex]
D. [tex]2\dfrac{2}{3} \ mile[/tex] below sea level
Step-by-step explanation:
The given parameters are;
The distance Sasha travels down before a stop = -2/3 mile
The level at which Sasha starts to hike into the canyon = Sea level
Therefore, we have;
Her elevation at the fourth rest station = 4 × -2/3 mile = -8/3 miles
Therefore, we have;
-8/3 mile = [tex]2\dfrac{2}{3} \ mile[/tex] below sea level
Therefore, the correct options are;
-8/3 mile and [tex]2\dfrac{2}{3} \ mile[/tex] below sea level.
