Jackie has a puzzle book that contains a total of 70puzzles she has completed 2/5 of the puzzle in the book if Jackie completes 18 more puzzles what is the total number of puzzles that she will has completed in the book ?
Answer: 46 puzzles
Step-by-step explanation:
There are 70 puzzles in total in the book.
Jackie has completed 2/5 of these puzzles which is:
= 2/5 * 70
= 28 puzzles
Jackie has completed 28 puzzles. She then completes 18 more. The total number of puzzles completed is:
= 28 + 18
= 46 puzzles
is x+y=3 and x+y=7 a one solution, no solution, or an infinitely many solution
Answer:
No solution
Step-by-step explanation:
The lines are parallel because they have the same slope.
Elimination method also just gives you 3 = 7 which is not true, therefore no solutions.

George solved the following system of equations using substitution.
y = 4.3 – 21
12x – 3y = 63
He decided there is no solution. After the following steps:
y= (4x – 21)
12x - 3(4x – 21) = 63
12:- 12.c + 63 = 63
63 = 63
Is George correct in his conclusion? If not choose the correct solution below. If he is correct, select that choice.
A) George is correct with no solution.
B) He is not right. There are infinitely many solutions.
C) He is not right. The solution is (63,63)
Answer:
B
Step-by-step explanation:
-4x + y = -21
12x -3y = 63
-4/12 = -1/3
1/-3 = -1/3
-21/63 = -1/3
If we graph the two lines, we can discover that are the same, so they have infinite points in common
URGENT, PLEASE ANSWERR If someone who is 5 feet tall uses a potato gun to shoot a potato in the air at 100 feet per second, we can use the function ℎ()=−162+100+5 to calculate how far the potato will be from the ground at any given second (t). What does the h(0) represent in the context of the problem?
Given:
Consider the function is:
[tex]h(t)=-16t^2+100t+5[/tex]
This function is used to calculate how far the potato will be from the ground at any given second (t).
To find:
The value of h(0) and its meaning in the context of the problem.
Solution:
We have,
[tex]h(t)=-16t^2+100t+5[/tex]
At t=0,
[tex]h(0)=-16(0)^2+100(0)+5[/tex]
[tex]h(0)=0+0+5[/tex]
[tex]h(0)=5[/tex]
Therefore, the value of h(0) is 5. It means the potato is 5 feet from the ground at the time of shooting.
Which pairs of fractions are equivalent? Mark all that apply. 4/5 and 8/12 2/3 and 10/15 1/6 and 3/18 2/7 and 6/20
Answer:
2/3 and 10/15 1/6 and 3/18
Step-by-step explanation:
to determine which fractions are equivalent, we multiply each fraction by 100
4/ 5 x 100 = 80
8/12 x 100 = 66.67
4/5 and 8/12 are not equivalent
2/3 x 100 = 66.7
10/15 x 100 = 66.7
2/3 and 10/15 are equivalent
If 10/15 is expressed in its simplest form. that is if both numerator and denominator are divided by 5, it would equal 2/3
1/6 x 100 = 16.7
3/18 x 100 = 16.7
1/6 and 3/18 are equivalent
If 3/18 is expressed in its simplest form. that is if both numerator and denominator are divided by 3, it would equal 1/6
2/7 x 100 = 28.6
6/20 x 100 = 30
2/7 and 6/20 are not equivalent

A construction worker drops a hammer from 25m. How long will it take for the hammer to hit the ground? H(t)= -4.9t^2 +v +h
Answer:
the time taken for the hammer to hit the ground is 2.26 s.
Step-by-step explanation:
Given;
height through which the hammer falls, h = 25 m
The time taken for the hammer to hit the ground is calculated as;
[tex]h(t) = ut + \frac{1}{2} gt^2\\\\h(t) = 0 + \frac{1}{2} (9.8)t^2\\\\h(t) = 4.9t^2\\\\t = \sqrt{\frac{h(t)}{4.9} } \\\\t = \sqrt{\frac{25}{4.9} } \\\\t = 2.26 \ s[/tex]
Therefore, the time taken for the hammer to hit the ground is 2.26 s.

Felipe calculated that he uses about 545 gallons of fuel each year. His car's owner's manual says that it is approved to use regular fuel. How much money can he save each year by switching from premium fuel, at $4.59 per gallon, to regular fuel at $4.18 per gallon?
$0.41
$2,501.55
$223.45
$2,278.10
$4,779.65
Answer:
$223.45
Step-by-step explanation:
premium fuel: 4.59 x 545
= 2501.55
regular fuel: 4.18 x 545
=2278.1
2501.55-2278.1 = 223.45

Answer:
23.32
Step-by-step explanation:
the hundredths place is the 2 spot after the decimal
and if the # to the right of that # is 5 or grater you add a one
if it is 4 or lower you keep the # the same
23.3238
because 3 is next to the second place the 2 just stays the same
so now it's

The lengths of the sides of the triangle are 13cm, 14 cm, and 15 cm. Is the triangle a right triangle?
Yes or No?
Show your work to receive brainliest! (lots of points)
Answer:
No, it is not a right triangle.
Step-by-step explanation:
If the triangle was a right triangle, then the Pythagorean Theorem states that a^2 + b^2 = c^2. Let's test it on this triangle:
13^2 + 14^2 = 365, or c^2. If this is a right triangle, c should equal 15.
However, sqrt(365) = 19.1, which is not 15. So, the triangle is not a right triangle.
Find the probability that you will roll an even number exactly 5 times when you:
roll a six-sided number cube 10 times.
P =0.246
roll a six-sided number cube 20 times.
P =0.015
Explain why the second result is less.
Answer:
Sample Response: As the number of trials changes, the distribution changes. Since there is a 50% chance of rolling an even number, having a small number of successes is less likely when the number of rolls increases.

The vertices of △JKL are J(−3, 4), K(3, 0), and L(−5, −4). The equation of the median to J is y=0. What are the coordinates of the centroid of △JKL?
Answer:j
Step-by-step explanation:
The coordinates of the centroid of △JKL are (-5/3 , 0)
What is centroid of a triangle and its coordinates?The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).
If the triangle has its vertices as [tex](x_1, y_1), (x_2, y_2) , \: (x_3, y_3)[/tex], then the coordinates of the centroid of that triangle is given by:
[tex](x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)[/tex]
The vertices of ΔJKL lies in first quadrant because the coordinated of the vertices are positive which means the vertices are in the form of (x,y).
If the ΔJKL reflects along the x-axis then the vertices are in the form of (x,-y). Now the ΔJKL reflects along the y-axis then the vertices are in the form of (-x,-y).
The given coordinates of the the vertices after transformation is J(−3, 4), K(3, 0), and L(−5, −4).
The equation of the median to J is y=0.
(-3 + 3 - 5 / 3 , 4 + 0 - 4/ 3) = (-5/3 , 0)

USing the SOH CAH TOA idenity
Adjacent = x
Hypotenuse = 8
Angle of elevation = 40 degrees
cos theta = adj/hyp
cos 40 = x/8
