Bradley answered 80% of the questions on his science test correctly. There were 30 questions on the test, and all the questions had equal value. How many questions did Bradley answer correctly on his test?
Answer:
he got 24 correct
Step-by-step explanation:
so basically yo do 30 divided by 10 to get 10 percent then you do that answer times 8 to get 80 percent yw xx
There are 24 answer correctly on his test.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Bradley answered 80% of the questions on his science test correctly.
And, There were 30 questions on the test.
Now,
Since, There were 30 questions on the test.
Hence, The correct answers = 80% of 30
= 80/100 × 30
= 24
Thus, Number of Bradley answer correctly on his test = 24

Answer:
(3, -2)
Step-by-step explanation:
Given:
y = -2x +4
Find:
the value of x for y=-2
Solution:
Put the value of y into the equation and solve for x:
-2 = -2x +4 . . . . use -2 for y
-6 = -2x . . . . . . . subtract 4
3 = x . . . . . . . . . .divide by -2
The solution of interest is (3, -2).
Which equation is perpendicular to y = 4x - 6 and passes through point (8, 12).
Answer:
The line is ;
4y = -x + 56
or
y = -x/4 + 14
Step-by-step explanation:
Generally, the equation of a straight line is;
y = mx + c
where m represents the slope
so for y = 4x - 6
The slope is 4
If two lines are perpendicular, the product of their slopes is -1
So for the second line, the slope will be -1/4
The equation in the point slope format will be ;
y-12 = -1/4(x-8)
y-12 = -x/4 + 2
Multiply through by 4
4y-48 = -x + 8
4y = -x + 8 + 48
4y = - x + 56
The equation of the line that passes through (8, 12) and is perpendicular to y = 4x - 6 is:
[tex]y - 12 = -\frac{1}{4} (x - 8)[/tex] (point-slope form)
or
[tex]y = -\frac{1}{4}x + 14[/tex] (slope-intercept form)
Recall:
Point-slope equation is given in the form of: y - b = m(x - a)Slope-intercept equation is given in the form of: y == mx + bWhere, m is the slopeThe slopes of two lines that are perpendicular to each other are the negative reciprocal of one another.Given:
y = 4x - 6
Slope (m) = 4The negative reciprocal of 4 is: -1/4To write the equation of a line that passes through (8, 12) and is also perpendicular to y = 4x - 6, substitute m = -1/4 and (8, 12) into
y - b = m(x - a)
Thus:[tex]y - 12 = -\frac{1}{4} (x - 8)[/tex] (point-slope form)
Rewrite in slope-intercept form
[tex]y - 12 = -\frac{1}{4} (x - 8)\\\\y - 12 = -\frac{1}{4}x + 2\\\\y = -\frac{1}{4}x + 2 + 12\\\\y = -\frac{1}{4}x + 14[/tex](point-slope form)
Therefore, the equation of the line that passes through (8, 12) and is perpendicular to y = 4x - 6 is:
[tex]y - 12 = -\frac{1}{4} (x - 8)[/tex] (point-slope form)
or
[tex]y = -\frac{1}{4}x + 14[/tex] (slope-intercept form)

Is (-3,4) a solution to the equation y=3x+107
O A solution
O Not a solution
Answer:
no
Step-by-step explanation:
its is not a solution, however if the equal sign actually looks like
[tex] \leqslant [/tex]
then it would be yes
Answer:
Not a solution
Step-by-step explanation:
( x, y ) = ( - 3, 4 )
x = - 3
y = 4
Substitute the values of x and y in the equation,
y = 3x + 107
4 = 3 ( - 4 ) + 107
4 = - 12 + 107
4 = 107 - 12
4 ≠ 95
Therefore,
( - 3, 4 ) is not a solution to the
equation y = 3x + 107.

Find the unknown angle measures
Answer:
Step-by-step explanation:
ok so this is a vetical angle. so they are equal to 180. so if 1 measurement is found the other is the difference of 180 and that angle measeurement.
so y is the same as 110
and 180 - 110 is 70, so x and z are equal to 70.
i hope this helped you :)
Answer:
y=110, x and z=70
Step-by-step explanation:
110 and y are congruent angles, so they both are 110 degrees.
both angles on the same side of the line always total 180 degrees,
so x and z must be 70.

A.1/5 B.3/10 C.7/5 D.4/5
Complete Question:
Maria rode her bike for three-fifths of a mile on Monday and one-fifth of a mile on Tuesday. How many miles did she ride altogether?
Group of answer choices.
A. 1/5
B. 3/10
C. 7/5
D. 4/5
Answer:
D. 4/5
Step-by-step explanation:
Given the following data;
Distance covered on Monday, D1 = 3/5 miles
Distance covered on Tuesday, D2 = 1/5 miles
Total distance covered, Td = D1 + D2
Substituting into the equation, we have;
[tex] Td = \frac {3}{5} + \frac {1}{5}[/tex]
Lowest common denominator (LCD) = 5
[tex] Td = \frac {3 + 1}{5} [/tex]
Td = 4/5 miles.
Therefore, Maria rode 4/5 miles altogether.

At the beginning of Grade 6, the ratio of advanced math students to the number of regular math students was 3: 8. After taking placement tests, students we removed around changing the ratio of advanced students to the number of regular students to 4: 7. How many students started in regular math and advanced math if there were 92 students in advanced math after the placement test?
Answer:
69 students were advanced and 184 were regular
Step-by-step explanation:
begining
advance 3: regular 8
after exam
advance 4 (92students) : regular 7 (92/4=23; 23*7=161 students)
So total students we have 161+92=253,
remember we have advance 3: regular 8 so
253/(3+8)=253/11=23
23*3=69, 23*8=184

What’s the equation of the line that passes through the points (7,-4) and (-7,1)
Answer:
5x +14y = -21
Step-by-step explanation:
One way to write the equation of a line from two points is ...
(y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0
(1 -(-4))(x -7) -(-7 -7)(y -(-4)) = 0
