Marita spent $13.0 at the grocery store. She bought pears, kiwis and pineaples. Pears cost $0.50 each, pineapples cost $1.50 each, and kiwis are $0.30 each. how many of each kind of fruit did she buy if she bought 9 more pears than pineapples and 2 fewer kiwis than pears?
Answer:
◘ 12 pears
◘ 3 pineapples
◘ 10 kiwis
Step-by-step explanation:
Let [tex]x[/tex] be the number of pears bought.
Therefore:
• number of pears = [tex]x[/tex]
• number of pineapples = [tex]x - 9[/tex]
• number of kiwis = [tex]x - 2[/tex]
We know that the total cost was $13.50.
This means if she bought [tex]x[/tex] pears at $0.50 each, [tex](x - 9)[/tex] pineapples at $1.50 each, and [tex](x -2)[/tex] kiwis at $0.30 each, the total would be $13.50.
∴ [tex][x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50[/tex]
Expanding and multiplying:
⇒ [tex]0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5[/tex]
Collect like terms:
⇒ [tex]2.3x -14.1 = 13.5[/tex]
Solve for [tex]x[/tex]:
⇒ [tex]2.3x = 13.5 + 14.1[/tex]
⇒ [tex]2.3 x = 27.6[/tex]
⇒ [tex]x = 27.6 \div 2.3[/tex]
⇒ [tex]x = \bf 12[/tex]
Therefore, she bought:
• 12 pears
• [tex]x - 9[/tex] = 12 - 9 = 3 pineapples
• [tex]x - 2[/tex] = 12 - 2 = 10 kiwis
Marita bought 12 pears, 3 pineapples and 10 kiwis.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
Let x the number of pears bought,
y the number of pineapples bought,
z the number of kiwis bought,
Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,
y + 9 = x
y = x -9 and
z + 2 = x
z = x - 2
We know that the total cost was $13.50.
This means if she bought pears at $0.50 each, pineapples at $1.50 each, and kiwis at $0.30 each, the total would be $13.50.
∴ 0.50x + 1.50y+ 0.30z = 13.50
Substitute the values of y and z in equation,
⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50
Expanding and multiplying terms in equation,
⇒ 0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50
Rearrange the like terms and apply the arithmetic operation
⇒ 2.3x - 14.1 = 13.50
⇒ 2.3x = 13.50 + 14.1
⇒ 2.3x = 27.6
⇒ x = 27.6/2.3
⇒ x = 12
Therefore, the number of pears bought = 12
So, the number of pineapples bought = 12 - 9 = 3
And the number of kiwis bought = = 12 - 2 = 10
Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

Is Figure BBB a scale copy of Figure AAA?
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.

Figure B is a scaled copy of Figure A.
What is the scale factor from Figure A to Figure B?
Answer: x = 60°
Step-by-step explanation:
We know a circle is equal to 360°, so we can subtract from 360° to find x using vertical angles and other given details.
Vertical (opposite) angles are equal to each other. This is why, for example, we know AGE and FGC are both 30°.
See attached for a breakdown of the angles.
360° - 30° - 30° - 90° - 90° = 2x
120° = 2x
60° = x
Answer:
x = 60°
Step-by-step explanation:
Hello!
The sum of angles on a line is 180°.
Given that Angle G is 90°, the other measure on Line DB would also be 90°. The missing angle next to x can be called y.
x° + y° = 90°Angle YThe Angle y can be calculated by using the Vertical Angles Theorem. The theorem states that if two non-adjacent angles are formed by the intersection of two lines, the measures of the angles are congruent.
This means that the measure of Angle y is 30°, as the 30° angle and y are non-adjacent and are formed by the intersection of lines AC and EF.
Angle XWe can now solve for x by plugging in 30° for y in the equation.
x° + y° = 90°x° + 30° = 90°x° = 60°The value of x is 60°.

Ariana looked at the mean and median of the rents. Then, she decided to remove the \$4{,}800$4,800dollar sign, 4, comma, 800 rent from the set and recalculate the mean and median.
How will removing this rent affect the mean and median?
The way that this action is going to affect the mean and the mean and the median value would be decreased than what it was supposed to be.
What is the mean?In a frequency distribution, the mean is the number that is used to represent the average of a group of data. To get the mean, you have to add up the numbers in the data set and divide by the total number in the data set.
The formula is fx/n
When the average of $4800 is removed from the data set, the mean is going to decrease by the number and the value of fx would also decrease. Hence we can conclude that it would cause the value to reduce.
The median is the middle value, it would also cause the median in the data set to be smaller than it was.

Step-by-step explanation:
Well like the question says the diameter of the toilet paper is 12 cm full both including the toilet paper and the tube. But we are also told the tube has a Diameter of 4. Taking this into consideration we both know that the tube will never get smaller but we do know the roll will decrease in size by half so while keeping the diameter of the tube at 4 we evenly remove half of the other 2 and we are left with a diameter of 2 / 4 / 2 in which giving us a total diameter of 8 therefore the diameter now being 8.

Which of the following is a line segment as shown in the drawing?
Answers:
- DH is correct because a line is connecting the two points D and H as shown in the image, forming a line segment.
- ED is correct because a line is connecting the two points D and E, forming another line segment, as shown in the drawing.
- EH is incorrect because in the drawing shown, there is no line connecting the two points E and H, so there would be no line segment formed between these two points.
- CD is correct because there is another line connecting the two points C and D, forming another line segment in the drawing.
Therefore, lines DH, ED, and CD are all line segments.
