Answer:
80 pages
Step-by-step explanation:
x = number of pages of articles
x = 110 - (23 + 14/2)
x = 110 - (23 + 7)
x = 110 - 30
x = 80
Eliza's book has a total of 357 pages. How many pages does Eliza read on Monday, Tuesday, and Wednesday combined?
The above question is incomplete.
Complete Question
Eliza reads of 1/7 of her book on Monday. On Tuesday and Wednesday combined, she reads three times as much as she reads on Monday. The expression 1/7r +3(1/7r) can be used to determine the number of pages Eliza reads on Monday, Tuesday, and Wednesday combined. The variable r represents the total number of pages in the book.
Eliza's book has a total of 357 pages. How many pages does Eliza read on Monday, Tuesday, and Wednesday combined?
Answer:
204 pages
Step-by-step explanation:
From the above question, we have the variable:
The expression 1/7r +3(1/7r) can be used to determine the number of pages Eliza reads on Monday, Tuesday, and Wednesday combined.
Hence:
r = 357 pages
Hence:
1/7r +3(1/7r)
1/7 × 357 + 3(1/7 × 357)
= 51 + 3(51)
= 51 + 153
= 204 pages
Therefore, the number of pages that Eliza read on Monday, Tuesday, and Wednesday combined is 204 pages

Answer:
The new coordinates are:
A' (6, 24)B'(12, 12)C'(-12, 6)Please check the attached graph.
Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged
If the scale factor is between 0 and 1, it gets shrunk
If the scale factor = 1, the object and the image are congruent
Given the vertices of the triangle in the diagram
A (1, 4)
B(2, 2)
C(-2, 1)
In our case:
Scale Factor K = 6Rule to calculate the dilation by a scale factor 6 centered at the origin
P(x, y) → P'(6x, 6y)
Here, P'(6x, 6y) ) is the image of P(x, y).
It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 6.Thus,
A (1, 4) → A'(6(1), 6(4)) → A'(6, 24)
B(2, 2) → B'(6(2), 6(2)) → B'(12, 12)
C(-2, 1) → C'(6(-2), 6(1)) → C'(-12, 6)
Therefore, the new coordinates are:
A' (6, 24)B'(12, 12)C'(-12, 6)Please check the attached graph.
The area of a right triangle is 270 square meters. The height of the right triangle is 15 meters. What is the length of the hypotenuse of the right triangle?
Answer:
[tex]\sqrt{549}[/tex] ≈ 23.4
Step-by-step explanation:
A = bh
270 = 15b
b = 18
Now you know the two legs, use the Pythagorean Theorem to find the value of the hypotenuse: a² + b² = c²
15² + 18² = c²
225 + 324 = c²
c² = 549
c = √549
factorise 8x^2 + 10x + 3
Answer:
Step-by-step explanation:
so 8^2 +10x+3 (if you times 8*3 -gives you 24)
the middle number is 10X right so then you have to guess two numbers that either add up or take away to make it a positive 10.
so example if i try 5+5 it gives me 10 but it i multiply 5 by 5 -it gives 25 therefore lets try another pair of numbers.
i chose 6 and 4 because when i add them it gives me 10 and when i multiply them, it gives me 24.
therefore im just going to:
8x^2+6x+4x+3
to factorise im going to use 2x
2x(4x+3) + 1(4x+3)
so my answer is (2x+1) and (4x+3)

Which options has the solution: [tex](x,y) = (-3,-3)[/tex]
[tex](a)[/tex] [tex]x - 5y =-12[/tex] and [tex]3x + 2y =-15[/tex]
Substitute [tex]x =-3[/tex] and [tex]y = -3[/tex] in [tex]x - 5y =-12[/tex] and [tex]3x + 2y =-15[/tex]
[tex]x - 5y =-12[/tex]
[tex]-3 - 5*-3 = -12[/tex]
[tex]-3 + 15 = -12[/tex]
[tex]12 \ne -12[/tex]
This is not a solution
[tex](b)[/tex] [tex]x - 5y =-12[/tex] and [tex]3x + 2y =15[/tex]
As shown in (a), (-3,-3) is not true for [tex]x - 5y =-12[/tex]
[tex](c)[/tex] [tex]x - 5y =12[/tex] and [tex]3x + 2y =-15[/tex]
Substitute [tex]x =-3[/tex] and [tex]y = -3[/tex] in [tex]x - 5y =12[/tex] and [tex]3x + 2y =-15[/tex]
[tex]x - 5y =12[/tex]
[tex]-3 - 5(-3) = 12[/tex]
[tex]-3 + 15 = 12[/tex]
[tex]12 = 12[/tex]
[tex]3x + 2y =-15[/tex]
[tex]3(-3) + 2(-3) = -15[/tex]
[tex]-9 - 6 = -15[/tex]
[tex]-15 = -15[/tex]
Hence,
(-3,-3) is true for [tex]x - 5y =12[/tex] and [tex]3x + 2y =-15[/tex]

https://brainly.com/question/24372553
The solution to the inequality 5 + h > 7 is h > 2. Graphing the solution involves representing the range of values for h that satisfy the inequality.
Here's a step-by-step explanation:
Start with the inequality 5 + h > 7.Subtract 5 from both sides of the inequality to isolate the variable h[tex]h > 7 - 5.[/tex]Simplify the right side of the inequality: [tex]h > 2.[/tex]The inequality h > 2 represents all values of h that are greater than 2. To graph the solution, draw a number line and mark the point 2.Since the inequality is "greater than," place an open circle at 2 to indicate that 2 is not included in the solution.Shade the region to the right of the open circle to represent all the values greater than 2.Label the shaded region with an arrow pointing towards the right to indicate that the values continue indefinitely in that direction.The resulting graph represents the solution to the inequality [tex]h > 2[/tex].In summary, the solution to the inequality 5 + h > 7 is h > 2. Graphing the solution involves marking an open circle at 2 on a number line and shading the region to the right, indicating all values greater than 2.

Sprinkler heads come in all different sizes depending on the angle of rotation desired. If a sprinkler head rotates 90 ° and has enough pressure to keep a constant 25-foot spray, what is the area of the sector of the lawn that gets watered? Round to the nearest square foot.
Answer:
491 ft²
Step-by-step explanation:
We know the area of a sector, A = Ф/360° × πr² where Ф = angle subtended by sector = angle of rotation of sprinkler = 90° and r = radius of sector = length of spray = 25 feet.
Substituting the values of the variables into the equation, we have
A = Ф/360° × πr²
A = 90°/360° × π(25 ft)²
A = 1/4 × 625π ft²
A = 1/4 × 1963.5 ft²
A = 490.9 ft²
A ≅ 491 ft² to the nearest square foot

Find the distance between Riverside and Milton if they are 15 cm apart on a map with a scale of 4 cm: 21 km.
pls answer i will give points
Answer:
66.9375
Step-by-step explanation:
from what you told me 4cm=21km
if you divide 21 by four, you get how many km is one cm. which is 5.25km
15 divided by 4 = 3.75
what we know is that 4 can go into 15 three whole times. so.. 21x3=63
now what we need to figure out is that .75
so, 75 is three quarters, so i divided 5.25 divided by 4 to get how much one quarter of a cm is in km. then i multipled that by three, giving me: 3.9375
63+3.9375= 66.9375
but you might have to round this i dont know if you do or not so thats the answer im giving
