How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?

Answers

Answer:

The number of 1/5 liter glasses that Lin can fill is [tex]7\frac{1}{2}[/tex]

Step-by-step explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

so

[tex]1\frac{1}{2} :\frac{1}{5}[/tex]

Convert mixed number to an improper fraction

[tex]1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}[/tex]

substitute

[tex]\frac{3}{2} :\frac{1}{5}[/tex]

Multiply in cross

[tex]\frac{5*3}{2*1}=\frac{15}{2}=7.5[/tex]

Convert to mixed number

[tex]7.5=7+\frac{1}{2}=7\frac{1}{2}[/tex]

Final answer:

Lin can fill 7.5 glasses of water from a 1 1/2 liter bottle. However, if only full glasses are counted, Lin can fill 7 full glasses.

Explanation:

The question asks how many 1/5 liter glasses can be filled with a 1 1/2 liter bottle of water. To answer this, we need to perform a division of the total volume of the water by the volume of each glass.

First, express both quantities in the same units, in liters. The bottle has 1 1/2 liters, which is the same as 1.5 liters. Now, divide the total volume of the water by the volume of one glass:

1.5 liters / (1/5 liter per glass) = 1.5 * 5 = 7.5 glasses.

Therefore, Lin can fill 7.5 glasses of water from a 1 1/2 liter bottle, if we consider that partial glasses can be filled. If only full glasses can be filled, Lin can fill 7 full glasses.

Pirate Jack has an equal number of gold and silver coins. If Pirate Jack splits all of his coins into 7 equal piles for his parrots, he has 4 coins left. Or, if he splits all of his coins into 11 equal piles for his shipmates, he has 4 coins left. Assuming every pile has at least 1 coin, what is the least possible number of coins Pirate Jack has?

Answers

The least possible number of coins Pirate Jack has, is 81 coins.

Step-by-step explanation:

Given,

When the coins are divided into 7 equal piles, 4 coins are left.

When the coins are divided into 11 equal piles, 4 coins are left.

We will take LCM of both 7 and 11.

7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, ....

11 = 11, 22, 33, 44, 55, 66, 77, 88, ...

The least common multiple of 7 and 11 is 77.

As 4 coins are left, therefore, we will add those coins.

Total possible coins = 77+4 = 81

The least possible number of coins Pirate Jack has, is 81 coins.

Which of the following must be true in order for SAND to be in a rhombus? Select all that apply

Answers

a) Consecutive sides must be congruent, for SAND to be in a rhombus

For the word "SAND" to form a rhombus, certain conditions must be met based on the properties of a rhombus:

a) Consecutive sides must be congruent: True. In a rhombus, all sides are congruent, so consecutive sides must also be congruent.

b) Diagonals do not bisect the angles: False. In a rhombus, the diagonals bisect the angles. This is a property of rhombuses.

c) All interior angles add up to 360: False. In a rhombus, all interior angles are equal, but their sum is not necessarily 360 degrees. However, the sum of all interior angles in any quadrilateral (including a rhombus) is indeed 360 degrees.

Therefore, the correct statement is:

a) Consecutive sides must be congruent

B) a = 2, b = 8
C) a = 6, b = 4
D) a = 3, b = 7
E) a = 12, b = -2

Answers

Answer:

C) a = 6, b = 4

Step-by-step explanation:

6 + 4 = 10

6 - 4 = 2

Final answer:

To solve the system, we first add both equations to find 'a = 6'. Then, substitute 'a' in one of the original equations to get 'b = 4'. The solution is 'a = 6' and 'b = 4', corresponding to answer choice C).

Explanation:

To solve the system of equations:

a + b = 10a - b = 2

We can add the two equations to eliminate the variable b. By adding them, we get:

2a = 12

Divide both sides of the equation by 2:

a = 6

With the value of a known, substitute a = 6 into either of the original equations. For example, substituting it into the first equation:

a + b = 10

6 + b = 10

b = 10 - 6

b = 4

Therefore, the solution to the system of equations is a = 6 and b = 4, which corresponds to answer choice C).

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-4, -2), B(-2, -2), C(-2, 7)C(−2,7)C, D(-4, 7
What is the area of rectangle ABCD?

Answers

Answer:

The area of rectangle ABCD is [tex]18\ units^2[/tex]

Step-by-step explanation:

Plot the figure to better understand the problem

we have the vertices

A(-4, -2), B(-2, -2), C(-2, 7), D(-4, 7)

see the  attached figure

The area of the rectangle is equal to

[tex]A=LW[/tex]

where

L is the length

W is the width

In this problem we have

[tex]L=BC=7-(-2)=9\ units[/tex] ---> difference of the y-coordinates

[tex]W=AB=-2-(-4)=2\ units[/tex] ---> difference of the x-coordinates

substitute

[tex]A=(9)(2)=18\ units^2[/tex]

Final answer:

The area of rectangle ABCD is calculated as 18 square units by finding the product of its width (2 units) and height (9 units).

Explanation:

The area of rectangle ABCD with vertices A(-4, -2), B(-2, -2), C(-2, 7), and D(-4, 7) can be calculated by finding the lengths of the sides AB and BC. The length of AB (width) is the difference in the x-coordinates of A and B, which is |-2 - (-4)| = 2.

The length of BC (height) is the difference in the y-coordinates of B and C, which is |7 - (-2)| = 9. Therefore, the area of rectangle ABCD is the product of the width and height, which is 2 * 9 = 18 square units.

b.QR = 5.9 cm
c.Measure of angle R = 28 degrees
d.Measure of angle R = 47 degrees

Answers

The true statement about triangle is: b. QR = 5.9 cm.

To understand what it means for two triangles to be congruent. When two triangles are congruent (△PQR ≌ △WVX), all corresponding sides and angles are equal.

Given:

VW = 4.5 inchesWX = 5.9 inches∠W = 28°∠X = 47°

For the triangles to be congruent, the corresponding sides and angles must be equal. Let's match the corresponding parts:

QR corresponds to WXPQ corresponds to VWm∠R corresponds to m∠Wm∠Q corresponds to m∠X

Given this correspondence:

QR must be equal to WX, so QR = 5.9 inches (Option b).

m∠R must be equal to m∠W, so m∠R = 28° (Option c).

m∠Q must be equal to m∠X, so m∠Q = 47° (Option d).

However, m∠R and m∠Q cannot both be correct choices simultaneously; only one can be correct because they refer to the same angle in each corresponding pair QR = 5.9 inches is the correct choice considering the triangle sides.

The question is about calculating the center of mass for a triangular sandwich with a semicircular bite and determining the volume and uncertainty for a rectangular box.

Explanation:

The question asked concerns finding the center of mass of a triangular sandwich after taking a semicircular bite out of it, which is a problem related to geometry and mass distribution. When solving such problems, one would typically have to calculate the area of the original triangle and the area of the semicircular bite, then find the centroid of both shapes.

For the rectangular box's volume and uncertainty, this is a measurement and uncertainty calculation question. Here, one must apply the formula for the volume of a rectangle (length  imes width  imes height) and use the rules of propagation of uncertainty to calculate the overall uncertainty of the volume measurement.

A circuit board manufacturer can produce 2000 board per hour. How many days will it take to produce 16500 if the company has a 10 hour work shift

Answers

Answer:

B. Less than a day

Step-by-step explanation:

From the question, the circuit board manufacturer produces 2000 board per hour.

Let x be the number of hours it will take to produce 16500 boards .

That’s

2000 boards = 1 hour

16500 boards = x hour

An image point of a transformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(6, -12), what was the transformation and scale factor?

reflection with scale factor 3
reflection with scale factor 1/3
dilation with scale factor 3
dilation with scale factor 1/3

Answers

Answer:

Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3

Step-by-step explanation:

i) the pre-image co-ordinates is  Y(6, -12)

ii) the coordinates of the image is Y' (2, -4)

iii) therefore we can clearly see that if we divide the coordinates of the pre-image (6,-12) by 3 then we get the coordinates of the image(2,4).

Therefore this is a dilation with scale factor of 1/3.

Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3

Final answer:

The transformation from the pre-image point Y(6, -12) to the image point Y'(2, -4) is a dilation with a scale factor of 1/3.

Explanation:

Given an image point Y'(2, -4) of a transformation and the pre-image point Y(6, -12), we can determine the type of transformation and the scale factor. The transformation is a type of change that affects the position, size, or shape of a figure. To find out the type of transformation and the scale factor, we compare coordinates.

Since the x-coordinate changed from 6 to 2, it has been reduced by a factor of 3 (6 divided by 3 equals 2). The y-coordinate changed from -12 to -4, which also has been reduced by a factor of 3 (-12 divided by 3 equals -4). This consistent reduction indicates that the transformation is a dilation. The objects are shrunk uniformly in both dimensions by the scale factor.

The correct answer is therefore dilation with scale factor 1/3.

Ben bowled 121 and 184 in his first two games. What must he bowl in his third game to have an average of at least 170​?

Answers

Answer:

205

Step-by-step explanation:

Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.

Final answer:

For Ben to have an average of at least 170 in his third game, he must bowl a score of 205.

Explanation:

To find out what Ben must bowl in his third game to have an average of at least 170, we can use the formula for average: average = total score/number of games.

In this case, Ben has played two games and wants to have an average of 170. So we can set up the equation: 170 = (121 + 184 + x) / 3, where x represents his score in the third game.

To solve for x, we can multiply both sides of the equation by 3 to get rid of the fraction: 510 = 121 + 184 + x.

Then, we can combine the numbers on the right side: 510 = 305 + x.

Finally, subtracting 305 from both sides gives us: 205 = x.

Therefore, Ben must bowl a score of 205 in his third game to have an average of at least 170.
