Answer:
A. $23.34
Step-by-step explanation:
The computation of the amount of money spend altogether is given below:
= Purchase price of 4 binder + pack of pencils + new coat
= $2.14 + $1.25 + $19.94
= $23.34
We simply added the above three cost so that the total money incurred would be come
Hence, the correct option is A
Please answer the question in the picture shown with work provided.
Answer:
a). (-0.04x² + 3x + 49)
b). 79240
Step-by-step explanation:
a). Population of the pet dogs of a two is given by the expression,
(38 + x - 0.04x²)
And population of the pet dogs of the rest of the towns of the county by (2x + 21).
Where x = Number of years from year 2007
Therefore, total population of the county = (38 + x - 0.04x²) + (2x + 21)
= -0.04x² + (x + 2x) + (38 + 21)
= (-0.04x² + 3x + 49)
b). Difference of years between year 2007 and 2019 = 12 years
Therefore, predicted population in year 2019 = -0.04(12)² + 3(12) + 49
= 36 + 49 - 5.76
= 79.24
Since, population is in thousands,
Therefore, total population of the county = 79.24 × 1000 = 79240

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

Solve the system by substitution
6х + 2y = -26
x – 6у = 21
Answer:
y=-4
x=-3
Step-by-step explanation:
6x+2y=-26 (equation 1)
-6x+36y=-126 (equation 2)
38y=-152
Both side divide by 38
[tex]\frac{38}{38}[/tex]y=[tex]\frac{-152}{38}[/tex]
y=-4
substitution y=-4 in(equation 1)
6x-8=-26
6x=-18
x=-3
substitution y=-4 in(equation 2)
x+24=21
x=-3

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

Answer:
AAS Postulate.
Step-by-step explanation:
The AAS Postulate states that if 2 angles and a non-included side are congruent on both triangles, then the two triangles are equivalent.
In this case, the first Angle is: ∠B ≅ ∠D (Given, both are 90° in measurement)
For the side: Line BE ≅ line DE (Given)
∡BEA ≅ ∡DEC (Definition of Vertical Angles)
AAS Postulate is therefore used.

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

WHICH IS RIGHT
I WILL MARK BRAINLIEST TO WHOEVER ANSWERS FIRST AND CORRECTLY!!!
Answer: You are correct. It is the upper-right corner.
This diagram shows the regression line (aka line of best fit), to be closest to all of the data points. It won't go through all of the data points, but it is the next best thing by getting as close as possible.
Something like the lower right corner shows the line only going through one point and it's not really close to the majority of the other points. It's close to only one or two points, and that's about it. The lower left corner is a similar story.
The upper left corner is fairly close, but the upper points are being left out. We should shift the regression line upward to make it look like what is shown in the upper right corner. We can think of it like a balancing act.

Answer: LM = 57
==========================================================
Explanation:
A median of a triangle goes from a vertex to the midpoint of the opposite side. The three medians of this triangle are these segments:
LMJNKPThe three medians intersect at the centroid point, which is point Q.
It turns out that the centroid cuts each median such that LQ is twice as long compared to QM. We can say
LQ = 2*QM
Applying the segment addition postulate and substitution, we then get,
LQ + QM = LM
2QM + QM = LM
3QM = LM
LM = 3QM
Now let's use LQ = 38 to find QM
LQ = 2*QM
38 = 2*QM
QM = 38/2
QM = 19
This then means,
LM = 3QM
LM = 3*19
LM = 57
Segment LM is 57 units long.
