When Mariana does 19 push-ups and 6 sit-ups, it takes a total of 75 seconds. In comparison,
she needs 72 seconds to do 18 push-ups and 6 sit-ups. How long does it take Mariana to do
each kind of exercise?
HELP
Answer: It takes 3 seconds to do one of both i think
Step-by-step explanation:
19 and 6 was 75 and 18 and 6 was 72 which means 1 push up is 3 seconds multiply 3 by 18 that is 54 then subtract 72 by 54 which gives you 18 then divide 18 by 6 which is 3

Y. O
Z. A
Parents
1. The Wheelers/ A and AB
II. The Byers/ AB and O
Ill. The Hendersons/ O and B

Meredith has 8 pages of homework to do. If she can finish of a page in one hour, how
many hours will her homework take?
Answer: 8 Hours to finish her homework.
Step-by-step explanation: We know each page, or 1 page takes 1 hour to finish. We want to know how many hours it would take to take finish 8 pages of homework. To find this, simply multiply 1 by 8. (1 hour per page, or 1 hour for each of the 8 pages.)
1 x 8 = 8.
So it will take Meredith 8 hours to finish her homework.
Answer:
it will take 8 hours if you mean one page an hour

The image of RST in the graph shown below is rotated 90°counterclockwise around the origin to form R'S'T'.
Answer:
Please check the explanation.
Step-by-step explanation:
Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.
In other words,
P(x, y) → P'(-y, x)
From the given triangle ΔRST,
The coordinates of the point S is:
S(10, 1)According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:
S(10, 1) → S'(-1, 10)
Here,
S'(-1, 10) is the image of the original point or pre-image point S(10, 1).
Therefore, the y-coordinate of the point S' is: 10

Answer:
12.68
Step-by-step explanation:
With reference angle 45°
perpendicular (p) = 9
hypotenuse (h) = c
Now
sin 45 ° = p/ h
0.71 = 9 / c
c = 9 / 0.71
c = 12.68

Find the unknown sides and angles of this triangle using the Law of Cosines. Round to the nearest hundredth.
Step-by-step explanation:
as we know
law of cosine
[tex]c = \sqrt{ {a}^{2} + {b}^{2} - 2ab. \cos(c) } [/tex]
[tex]c = \sqrt{ {14}^{2} + {18}^{2} - 2.14.18 - \cos( {35}^{o} ) } [/tex]
[tex]c = 10.35[/tex]
using the law of cosine
[tex]cos(a) = \frac{ {b}^{2} + {c}^{2} - {a}^{2} }{2bc} [/tex]
[tex] \cos(a) = \frac{ {18}^{2} + {10.35 }^{2} - {14}^{2} }{2.18.(10.35)} [/tex]
[tex]a = {50.87}^{o} [/tex]

IF THE VOLUME OF THE BOX BELOW IS
x3 + 6x2 + 9x + 4
AND THE WIDTH OF THE BOX IS x + 4,
THEN FIND THE LENGTH AND HEIGHT OF
THE BOX
Answer:
The length of the box is (x + 1)
The height of the box is (x + 1)
Step-by-step explanation:
The given function representing the volume of the box is presented as follows;
V = x³ + 6·x² + 9·x + 4
The function representing the width of the box, W = x + 4
Therefore, we have;
(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1
x³ + 4·x²
[tex]{}[/tex] 2·x² + 9·x + 4
[tex]{}[/tex] 2·x² + 8·x
[tex]{}[/tex] x + 4
Therefore, we have;
(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)
(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)
The width of the box = (x + 4)
The length of the box = (x + 1)
The height of the box = (x + 1).
consider the line y=-5/4x+4. What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
m = 4/5 for the perpendicular line
m = -5/4 for the parallel line
y = -5/4x + 3
for the line above, m = -5/4
The line parallel to this line would have exactly the same slope m = -5/4
The line perpendicular to this line would have a slope equal the inverse with the opposite sign
m = -5/4
So m = (1/(5/4)) is the slope of the m for the perpendicular line
m = 4/5

first part: put them equal to each other
6x - 25 + 4x = 45 + 3x - 7
10x - 25 = 38 + 3x
7x - 25 = 38
7x = 63
x = 9
second part: plugin
6x - 25 + 4x
6(9) - 25 + 4(9)
54 - 25 + 36
29 + 36
= 65
-- plugging this in one of the equation is enough, since both are the same.
final answer for the second part: 65

Step-by-step explanation:
To add fractions, find the LCD and then combine.
Answer:
7/10
Step-by-step explanation:
First, find the smallest possible denominator between the two fractions. The smallest one is 20.
Now, both denominators need to become 20. To get the 5 in 1/5 to become 20, it needs to be multiplied by 4. Whatever you do to the denominator, you must do to the numerator.
1 x 4 = 4
The first fraction is now 4/20.
To get the 4 in 2/4 to become 20, you must multiply it by 5. Whatever you do to the denominator, you must do to the numerator.
2 x 5 = 10
The second fraction is now 10/20.
Add the fractions. Keep the denominators the same and add the numerators.
4/20 + 10/20 = 14/20
Simplify by dividing both numbers by 2
7/10

Answer:
No, X=7
Step-by-step explanation:
Answer:
Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:
x-4y=6
x+4y=12
we see here that elimination would best fit:
x+x+4y-4y=6+12
or:
x=2y-3
7x+3y-81=23
substitute (2y-3) for x.
Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)
and use the quadratic formula:
x=(-b±sqrt(b^2-4ac))/2a

Answer:
1) see below
2) 2.5 inches per day
3) the seed was planted below ground level
4) h = 2.5d -3
Step-by-step explanation:
1) We note that the seedling grew 12-7 = 5 inches in the 2 days between day 4 and day 6. This lets us fill in the numbers for even days by adding or subtracting 5 inches:
day 8 will be 5 inches more than day 6, 17 inches.
day 2 will be 5 inches less than day 4, 2 inches.
day 0 will be 5 inches less than that, -3 inches.
The value for day 3 will be halfway between day 2 and day 4, so will be (2+7)/2 = 4.5 inches.
See the attachment for the complete table.
__
2) In one day, the plant grows in/day = 5/2 = 2.5 inches.
__
3) If the plant grows at the steady rate of 5 inches in 2 days, it must have been planted 3 inches below ground on day 0.
__
4) In question 2, we found the rate per day (slope) to be 2.5. In question 3, we found the "y-intercept" to be -3. Then the slope-intercept equation with independent variable d and dependent variable h is ...
h = 2.5d -3
An airplane moves at a constant speed of 120 miles per hour for 3 hours. How many miles does it go?
Answer:
120 miles per hour
total time 3 hours
120 x 3= 360
the plane travels 360 miles
Step-by-step explanation:
Answer:
Someone calculated his or her average speed to 7.46 Miles per hour (mph) This calculation will help you calculate your average speed when you have covered a certain distance over a certain time.
Step-by-step explanation:
The re sults your produce from the speed calculator input will come out in a variety of forms You can also find a report on your speed in terms of kilometres per hour, meters per minute and metres per second. There is also a report on the time it takes you to travel certain distances. This report shows you min:sec per kilometre, seconds per 100 .

Answer:
8) y = x/2 + 6
9) x = -(7/4)
Step-by-step explanation:
for (8), start with point-slope form and enter -2, 5, and 1/2 into the appropriate places:
y-5 = (1/2)(x- -2)
simplify by distributing (1/2)
y-5 = x/2 + 1
add 5 to both sides to get yourself in slope-intercept form
y = x/2 + 6
for 9, start by distributing the 3 and the 2
6x-12 = 10x-8+3
combine like terms
6x-12 = 10x-5
subtract 6x from both sides
-12 = 4x-5
add 5 to both sides
-7=4x
divide both sides by 4
-(7/4) = x
x3+15=x9-3 pls answer
id-k but here we go
have you seen things of circles and triangles and squares? This problem is just like this. You would probably identify the squares circles and triagnles as...well....traingles circles and squares. Well, we do that but with the variables.
The numbers with 'x' is one group. And the one without it is another group. So....take 'x3' and take the x9. Because they have the same variable.
x3 + x9. (why we are adding is because it has nothing to drag with it and both of these numbers are positive)
x12!
Now do teh same with 15 and 3. Bring the plus and the subtraction sign with 3 and 15. We cant just leave them there. 15-3=12.
we have 12. this must equal 12!!!!!
Evaluate: (9 - 3)² + 5 ÷ ⅓
Answer:
123
Step-by-step explanation:
(6^2+5)*3= 41*3= 123
Answer:
Step-by-step explanation:
take away the parenthesis
9 - 3 = 6
6² + 5 ÷ ⅓
take away the exponents
6 * 6 = 36
36 + 5 ÷ ⅓
36 + 5 = 41
41 ÷ ⅓
( 41 ÷ 1 ) ÷ 3
41 ÷ 3
