Question 1
You answer 24 questions on a 100-point test correctly and earn a 96%.
a. All of the questions are worth the same number of points. How many questions are on the test? How many points is each question worth?
There are
questions on the test.
Each question is worth
points.
Question 2
b. Your friend earns a grade of 76% on the same test. How many questions
did your friend answer correctly?
Your friend answered
questions correctly.
Answer:
a 25 questions, 4 points b 19 questions
Step-by-step explanation:
a 96:100 = 24 : x
x = (100 x 24)/96 = 25 questions
100 : 25 = 4 points
b 76:100 = x : 25
x = (76 x 25)/100 = 19 questions
Answer:
Question 1:
There are 25 questions on the test.
Each question is worth 4 marks each.
Question 2:
Your friend answered 19 questions correctly
Step-by-step explanation:
Question 1:
question answered = 24
percent earned = 96%
total number of points = 100%
[tex]\frac{questions answered }{percentage earned}[/tex] x 100
[tex]\frac{24}{96}[/tex] x 100 ⇒ 0.25 x 100 ⇒ 25
there are 25 questions on the test
[tex]\frac{100}{25} = 4[/tex]
each question is 4 marks each
Question 2:
percent earned by your friend = 76%
(percent earned by your friend x total number of question) ÷ 100
76 x 25 ÷ 100
1900 ÷ 100
= 19

Oscar is planning to paint his house. For stability, the foot of his 17-foot ladder should be placed 4 feet from the house. How far up the side of the house will the ladder reach?
Answer: The side of the house will the ladder reached by ladder = 16.52 feet
Step-by-step explanation:
House is standing vertical on the ground.
By placing ladder, it will become a right triangle with hypotenuse as ladder.
By Pythagoras theorem,
[tex](hypotenuse)^2=(perpendicular)^2+(base)^2[/tex]
i.e.
[tex](17)^2=(Height \ of\ wall\ reached\ by\ ladder)^2+4^2\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=289-16\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=273\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)=\sqrt{273}\approx16.52[/tex]
Hence, the side of the house will the ladder reached by ladder = 16.52 feet (approx)

what is an equation of the line that passes through the point (-5, 7) and is parallel to the line x+5y=10?
Answer:
y = -1/5x + 6
Step-by-step explanation:
First rearrange x + 5y = 10 into y = mx + b format.
x + 5y = 10
5y = -x +10
y = -1/5x + 2
If a line is parallel to y = -1/5x + 2, it must have the same slope (-1/5).
Plug in for y = mx + b
x (x coordinate) = -5
y (y coordinate) = 7
m (slope) = -1/5
Solve for b.
7 = -5(-1/5) + b
7 = 1 + b
b = 6
y = -1/5x + 6 is parallel.

A taste-testing survey of Zing Farms showed that 2/3 people surveyed preferred the taste of veggie burgers to regular burgers. If 90,000 people were in the survey , how many favored veggie burgers? How many chose regular burgers ?
Answer:
60,000 chose veggie burgers.
30,000 chose regular burgers.
Step-by-step explanation:
90,000 x 2/3 = 60,000
90,000 x 1/3 = 30,000
Hope that helps!
The number of people preferred the veggie burgers is 60,000 and the number of people preferred the regular burgers is 30,000.
Given that, a taste-testing survey of Zing Farms showed that 2/3 people surveyed preferred the taste of veggie burgers to regular burgers.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, 2/3 × 90,000
= 2 × 30,000
= 60,000
So, number of people preferred the regular burgers = 90,000-60,000
= 30,000
Therefore, the number of people preferred the veggie burgers is 60,000 and the number of people preferred the regular burgers is 30,000.

Answer:
EZ Excavation: y = 24.5x
Happy Hauling Service: y = 25x
Step-by-step explanation:
✔️Equation for EZ Excavation:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using any given pair of values from the table, say, (8, 196),
k = 196/8
k = 24.5
To write the equation, substitute k = 24.5 into y = kx
Thus:
y = 24.5x
✔️Equation for Happy Hauling Service:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using the coordinate of any point on the line, say (1, 25),
k = 25/1
k = 25
To write the equation, substitute k = 25 into y = kx
Thus:
y = 25x
can someone please help me with this? (i will mark brainliest) (LMNP is rotated 180 degrees clockwise around the origin. what are the coordinates of L?)
Answer:
L's coordinates would go from being (x,y) to (-x, -y)
Step-by-step explanation:
So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)
If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L
Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)

Step-by-step explanation:
A kitchen was remodeled and granite counter tops were installed A rectangular island in the kitchen now has a granite top measuring 8 ft by 5.3 inches. The density of granite is 2.7 kg/cm3.
don't forget to change to inches to feet and feet to centimeters.
how much does the counter top weigh in pounds? 1 kg= 2.2 pounds .
Answer:
Problem: if I correctly recall from my days of carving tombstones, the density of granite is not 2.7 kg/cm³, but 2.7 g/cm³
At 2.7 kg/cm³, the weight is 3,664,392 pounds
at 2.7 g/cm³, the true weight is 3664.39 pounds
Step-by-step explanation:
8 ft = 243.84 cm
5.3 inches = 13.46 cm
6 ft 2 in = 187.96 cm
volume = 243.84 cm x 13.46 cm x 187.96 cm = 616,901.01 cm³
616,901.01 cm³ × 2.7 kg/cm³ x 2.2 lb/kg = 3,664,392 pounds
2.7 g/cm³ = 0.0027 kg/cm³
616,901.01 cm³ × 0.0027 kg/cm³ x 2.2 lb/kg = 3664.39 pounds

Write the slope-intercept form of the equation of the line parallel to the
graph of 2x + y = 5 that passes through (0, 1).
Answer:
y = -2x + 1Step-by-step explanation:
2x + y = 5 ← given line
2x + y = C ← any parallel line
The line passing through (0, 1), therefore:
2×0 + 1 = C
C = 1
2x + y = 1 ← the parallel line that passes through (0, 1)
To change it to slope-intercept form we just need to subtract 2x from both sides:
y = -2x + 1

Answer:
[tex]g = \frac{ x - 2}{3} [/tex]
Answer: g=x-2/3
Step-by-step explanation:
When it says make g the subject it means make it on it's own in front of the '=' sign.
To make g the subject, you have to do the inverse to 'undo' the equation.
So, instead of adding 2, you have to take away 2 from x. This would now look like this:
x-2=3g
In algebra, when a number is next to a letter it means times. So instead of multiplying g by 3, you would have to divide x-2 by 3. This would now look like this:
x-2/3=g
Hope this helps :)
