Mark got 18 out of 25 questions correct on his science test. What percent of the questions did he get correct
Answer:
72%
Step-by-step explanation:
Turn the denominator to 100.
So: 18/25 times 4 equals 72/100
72/100= 72%
*You turn the denominator into 100 because all percents are out of 100.*

What number when subtracted from the sum of 5.6 and 9.4 will give 12.8? *
Answer:
2.2
Step-by-step explanation:
5.6-9.4=15.0
so you subtract 12.8 from 15.0 which gives you the answer 2.2 so your answer is 2.2

evaluate -3/5x+y by replacing x with -1/2 and y with 1/2 ?
yeah I’m bad at math help out this is frustrating.♀️
Substitute x with -1/2 and y with 1/2.
So the equation will look like this:
= -3/ 5(-1/2) + (1/2)
= -3/ -2.5 + 1/2
= -3/ -2
= 1.5
Therefore, the answer is 3/2 or 1.5.
The graph to the right represents the cost of a taxi where X is distance and y is cost in dollars what conclusion can you make?
A) the taxi costs $1
B) The taxi will only stop once
C)The taxi will only take you farther than 1 mile
D) The taxi costs $1 just to get into a taxi
Answer:
The taxi costs $1 just to get into a taxi
Step-by-step explanation:
The base cost the taxi charges for it to be hired is $1 which is the point on the graph where the line intercepts the y-axis. At that point, distance or miles travelled is 0.
Therefore, we can conclude that the taxi would charge a customer for just to get a taxi, and the total cost will be dependent on the additional charges paid in addition based on the number of miles the customer will be driven to their destination.
The $1 is just the charge fee paid by the customer in addition to the per-mile charge he would pay.
solve each of these equations.
2(x+5)=3x+1
Answer:
x = 9
Step-by-step explanation:
2(x + 5) = 3x + 1
open the parenthesis
2x + 10 = 3x + 1
subtract 2x from both sides of the equation
2x - 2x + 10 = 3x - 2x + 1
10 = x + 1
subtract 1 from both sides of the equation
9 = x
Answer:
Step-by-step explanation:
Substitute
2x+10=3x+1
Subtract 3x to other side
-x+10=1
Subtract 10
-x=-9
divide -1 both sides
x= 9
b. His sister, Janine, used a light bulb that consumed 6080 joules of energy in 190
seconds. What is the unit rate at which this light bulb used energy?
Answer: 32 joules per second. That is equivalent to 32 Watts
Step-by-step explanation:
Divide units by time . 6080/190 = 32
1 joule per second is one watt.

Step-by-step explanation:
You'll need to learn the formula for the circumference of a circle. If the radius is r, the circumference C is C = 2πr. It appears that your teacher is using pi for the exact circumference and 3.14 for the approximate circumference.
The radius of the first circle is 5 in. Thus, the exact circumference is
C = 2πr = 2π(5 in) = 10π in, and the approximate circumference is
C = 2(3.14)(5 in) = 31.4 in
How many teaspoons are in half an ounce?
Answer:
3
Step-by-step explanation:
Answer:
3 teaspoons
Step-by-step explanation:
There are 6 teapsoons in one ounce.
We are looking for the number of teaspoon in HALF an ounce.
We can divide by 2 to find half the number of teaspoons in one full ounce.
6 / 2 = 3 teaspoons per half an ounce.
Best of Luck!
Help!! Please! Its algebra!!
Answer:
y - 7 = -4 ( x -2 )
Step-by-step explanation:
just use the given informations:
The base formula:
y - y(1) = m ( x -x(1) )
remember that "m" typically refers to the slope of a line
There is a given set of points on the line: (2, 7)
hence just plug in the numbers:
x(1) = 2
y(1) = 7
m = -4
and you get
y - 7 = -4 ( x -2 )
Y=-4(x-2)
hope it helps

9514 1404 393
Answer:
{ (-441/23, 433/23) }
Step-by-step explanation:
The "cross-multiplication method" is usually shown as follows:
1. rewrite the equations in general form: ax +by +c = 0
2. write the coefficients in two row in the order b, c, a, b.
3. form three products, each being the number in the first row times the number to its right in the second row. That is, b1·c2, c1·a2, a1·b2
4. form three more products, each being the number in the second row times the number to its right in the first row. That is, b2·c1, c2·a1, a2·b1
5. form three differences, subtracting the products of step 4 from those of step 3. Call these differences d1, d2, d3. (For example, d1=b1c2-b2c1.)
6. The values of x and y satisfy the equations ...
x/d1 = y/d2 = 1/d3
which is to say, ...
x = d1/d3, and y = d2/d3
_____
For your equations, we can rewrite them as ...
11x +12y -15 = 012x +11y +23 = 0Then our rows of coefficients are ...
[tex]\begin{array}{cccc}12&-15&11&12\\11&23&12&11\end{array}[/tex]
And our differences are ...
d1 = 12(23) -11(-15) = 441
d2 = -15(12) -23(11) = -433
d3 = 11(11) -12(12) = -23
The relations between x and y are ...
x/441 = y/-433 = 1/-23
so, x = -441/23 and y = 433/23
The solution set is one ordered pair: { (-441/23, 433/23) }.

Additional comments
The final solution is identical to the formula arrived at using Cramer's Rule. Calling this the "cross-multiplication method" avoids any discussion of matrices and determinants.
