▹ Answer
$16.50
▹ Step-by-Step Explanation
If you are trying to find the new price, we will deduct 25% from the original cost of $22.
To figure this out, you can multiply 0.25 * 22.
From there, you will get $5.50. This means there will be a $5.50 discount applied. To find the new cost, we will now subtract.
$22 - $5.50 = $16.50
The new cost of the skateboard is $16.50.
Hope this helps!

25 pts! Will give brainliest, I need help with part b and c
Answer:
Only can print 20 page when it's half page
full page he only can print 10
Step-by-step explanation:
40x=800
800/40 = 20
75x=800
10 page only
Answer (part b):
20 half-page advertisements
Step-by-step explanation:
Michael has $800 and the company charges $40 per half-page advertisements. So you can just do 800/40 becuase you need to divide what is being charged ($40) by what Michael has ($800) and you’ll get 20. That’s okay because he said he can purchase 13 advertisements, but these are half-page advertisement. So it’s really just 10 full-page advertisements.
Answer (part c):
About 10 full-page advertisements
Step-by-step explanation:
Again, Michael has $800 and the company charges $75 per full-page advertisements. So you can just do 800/75 becuase you need to divide what is being charged ($75) by what Michael has ($800) and you’ll get 10.6, but the 6 is repeating. You will have to round down to 10 because if you round up, then he won’t have enough money to buy 11.
Hope this helps and answers your question :)
What is Fourteen minus four times y is equal to y increased by 4 in number form
Scott trained for the marathon.
On day 1, he took 70 min to run 10 km.
On day 10, he took 2 h 40 min to run 20 km.
On day 20, he took 4 h 15 min to run 30 km.
a) What was Scott's running rate, in minutes per kilometre,
for each day?
i) Day 1 ii) Day 10 iii) Day 20
b) What do you think Scott's running rate, in minutes per
kilometre, might be for the 44 km of the marathon?
How long do you think it will take him? Explain.
Answer:
See below
Step-by-step explanation:
a)
Day 1
70 min for 10 kmRate = 70/10 = 7 min/kmDay 10
2h40 min for 20 km2*60+40 = 160 min for 20 kmRate = 160/20 = 8 min/kmDay 20
4 h 15 min for 30 km4*60 + 15 = 255 min for 30 kmRate = 255/30 = 8.5 min / kmb)
From the rate change we see:
1 min increase when the distance increases from 10 km to 20 km0.5 min increase when distance increases from 20 km to 30 kmSo we see 1 min increase per twice the distance increase
With the same rate increase we can expect 1 min increase from 20 km to 40 km, which gives us the rate of 9 min/km With same logic we get 9.055 km/min rate for 44 km distanceTotal time it takes:
9.055*44 = 398.42 min = 398.42*1/60 min = 6 h and 38.42 minTo support a local senior citizens center, a student club sent a flyer home to the n students in the school. The flyer said, "Please bring in money to support the senior citizens center. Paper money and coins accepted!" Their goal is to raise T dollars. Match each quantity to an expression, an equation, or an inequality that describes it. A: the dollar amount the club would have if they reached half of their goal 1: B: the dollar amount the club would have if every student at the school donated 50 cents to the cause 2: C: the dollar amount the club could donate if they made $50 more than their goal 3: D: the dollar amount the club would still need to raise to reach its goal after every student at the school donated 50 cents 4: E: the dollar amount the club would have if half of the students at the school each gave 50 cents 5: Which statement matches with T + 50?
Answer:
the dollar amount the club would have if they reached half of their goal T + 50
the dollar amount the club would have if every student at the school donated 50 cents to the cause 0,5T
the dollar amount the club could donate if they made $50 more than their goal 0.25n
the dollar amount the club would still need to raise to reach its goal after every student at the school donated 50 cents 0.5n
the dollar amount the club would have if half of the students at the school each gave 50 cents T - 0.5n
Step-by-step explanation:
the dollar amount the club would have if they reached half of their goal T + 50
the dollar amount the club would have if every student at the school donated 50 cents to the cause 0,5T
the dollar amount the club could donate if they made $50 more than their goal 0.25n
the dollar amount the club would still need to raise to reach its goal after every student at the school donated 50 cents 0.5n
the dollar amount the club would have if half of the students at the school each gave 50 cents T - 0.5n
Solve for X, please give a brief run-over on how you got there.
Answer:
x = 31.5
Step-by-step explanation:
The triangle on the left has 2 congruent sides and is therefore isosceles.
Thus the 2 base angles are congruent with measure
[tex]\frac{180-54}{2}[/tex] = [tex]\frac{126}{2}[/tex] = 63
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
The triangle on the right is also isosceles with base angles of measure x
63° is an external angle of the triangle on the right, thus
x + x = 63
2x = 63 ( divide both sides by 2 )
x = 31.5
You and your friend are practicing for a rowing competition and want to know how far it is to an island in the Indian River Lagoon. You take measurements on your side of the lagoon and make the drawing shown. What is the distance to the island? Please help, I don't have much time.
The drawing is missing, so i have attached it.
Answer:
24 yards
Step-by-step explanation:
From the image, we can see that AB and DE are both adjacent sides of their respective triangles.
While, CE and BC are both opposite sides of their respective triangles
Now, from your side, x is the distance to the island.
So, from ratio of similar triangles, we can find x.
Thus;
8/x = 3/9
Cross multiply to get;
8 × 9 = 3x
3x = 72
x = 72/3
x = 24
Thus, distance from your side to the island is 24 yards

Answer:
To solve the first inequality, you need to subtract 6 from both sides of the inequality, to obtain 4n≤12. This can then be cancelled down to n≤3 by dividing both sides by 4. To solve the second inequality, we first need to eliminate the fraction by multiplying both sides of the inequality by the denominator, obtaining 5n>n^2+4. Since this inequality involves a quadratic expression, we need to convert it into the form of an^2+bn+c<0 before attempting to solve it. In this case, we subtract 5n from both sides of the inequality to obtain n^2-5n+4<0. The next step is to factorise this inequality. To factorise we must find two numbers that can be added to obtain -5 and that can be multiplied to obtain 4. Quick mental mathematics will tell you that these two numbers are -4 and -1 (for inequalities that are more difficult to factorise mentally, you can just use the quadratic equation that can be found in your data booklet) so we can write the inequality as (n-4)(n-1)<0. For inequalities where the co-efficient of n^2 is positive and the the inequality is <0, the range of n must be between the two values of n whereby the factorised expresion equals zero, which are n=1 and n=4. Therefore, the solution is 1<n<4 and we can check this by substituting in n=3, which satisfies the inequality since (3-4)(3-1)=-2<0. Since n is an integer, the expressions n≤3 and n<4 are the same. Therefore, we can write the final answer as either 1<n<4, or n>1 and n≤3.

The system of the equation that has only one solution is; 5x-4y=8 and 3x+2y=8.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We have to determine;
Which system of equations has only one solution
As per the question, a system of linear equations can have one solution if there is only one point that makes every equation in the system true. It implies that there is one point that can satisfy all of the equations at the same time.
The system of equations has only one solution is;
5x-4y=8
3x+2y=8
from equation 1
5x-4y=8
5x=8+4y
[tex]x=\frac{8+4y}{5}[/tex]
Putting the value of x in equation 2
3x+2y=8
[tex]3(\frac{8+4y}{5})+2y=8[/tex]
[tex](\frac{24+12y}{5})+2y=8[/tex]
24+12y+10y=[tex]5*8[/tex]
24+22y=40
22y=40-24
22y=16
y=[tex]\frac{16}{22}[/tex]
y=[tex]\frac{8}{11}[/tex]
Putting the value of b in equation 1,
3x+2y=8
3x+2[tex]\frac{8}{11}[/tex]=8
3x=8-[tex]\frac{16}{11}[/tex]
3x=[tex]\frac{88-6}{11}[/tex]
[tex]x=\frac{82}{33}[/tex]
Therefore, the system of equation which has exactly one solution are;
5x-4y=8 and 3x+2y=8.
