5% of 90 m =
m
25% of 88 kg =
kg
75% of 264 =

Answers

Answer:

1) 5% of 90m= 4.5m

2)25% of 88kg = 22kg

3) 75% of 264= 198

Step-by-step explanation:

1) 90m = 100% (divide by 10)

9 = 10% (divide by 2)

4.5 = 5%

2) 88kg = 100% (keep on dividing by 2)

44kg = 50%

22kg=25%

3) 264 = 100%

132 = 50%

66 = 25% (add)

198=75%

Which equation shows a slope of 2/3 and a y-intercept of (0,-2) ?

Answers

Answer:

Y=2/3x -2

Step-by-step explanation:

Slope 2/3

Y intercept -2

The equation which has a slope of 2/3 and a y-intercept of (0, -2) is; 2x -3y = 6

Slope and y-intercept of straight line equations

From line geometry, it follows that the slope of a given straight line is the rate of change in variable y due to a change in variable x.

Hence, the resulting equation is;

2/3 = (y -(-2))/(x-0)

By cross-multiplication;

3y + 6 = 2x.

Let A and B be arbitrary matrices for which the indicated product is defined. Determine whether the statement below is true or false. Justify the answer. If A and B are 2 x 2 with column a1,a2 and b1, b2 respectivley then AB= [a1b1, a2b2]

Each column of AB is a linear combination of the columns of B using weights from the corresponding column of A.

a. True
b. False

Answers

Answer:

b. False

Step-by-step explanation:

Let A and B be matrices with the rows a1a2 and b1b2 respectively. Suppose the other two columns are c1,c2 and d1d2 having a value equal to zero.

A=   a1   c1                      B=  b1       d1

      a2  c2                            b2      d2

Multiplying

AXB= a1b1+c1b2         a1d1+c1d2

          a2b1+c2b2       a2d1+c2d2

AB=║ a1b1         0║

      ║a2b1        0 ║

Hence the given statement is false.

Each column of AB is a linear combination of the ROWS of A using weights from the corresponding column of B.

The matrix multiplication is "row by column" i.e the rows of the first matrix are multiplied with the columns of the second matrix.

The rows are also used in multiplication.

A blackboard has an area of 28 ft2 and a perimeter of 22 ft. What are the dimensions of the board?

2 ft by 11 ft
2 ft by 14 ft
4 ft by 7 ft
7 ft by 7 ft

Answers

Answer:

Step-by-step explanation:

A=LW, L=A/W

P=2(L+W), using L=A/W we get

P=2(A/W+W)

P=2(A+W^2)/W

PW=2A+2W^2

2W^2-PW+2A=0, given A=28 and P=22 we have

2W^2-22W+56=0

2(W^2-11W+28)=0

2(W-7)(W-4)=0

So the dimensions are 4ft by 7ft

In order to graph a line from an equation that is written in slope intercept form, what do you plot first, then next.
O plot (b) first, then plot 9mo to rise and run to find other points.
O just plot the (b) on the y-axis only.
O plot (b) on the X-axis, then (m) on the y-axis.
Oplot (m) first to rise and run to find other points, then plot (b)

Answers

Answer:

first answer - you plot 'b' [on the y-axis] first, then use the slope m = c/d to go d units right and then c units up (positive 'c') or down (negative 'c')

which of the following are magnitudes for rotational symmetry of the rectangle below about the marked point?

​

Answers

Answer:

The answer is B.180°.

Step-by-step explanation:

The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.

In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.

Therefore, the only option that applies is B.180°

B

Answers

Answer:

Step-by-step explanation:

When the sum of two angles is 90°, then the angles are known as complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. Here we say that the two angles complement each other. Suppose if one angle is x then the other angle will be 90 o – x

12% of students of a class of 50 like blue
colour. How many children like blue colour?​

Answers

Answer:

6 children

Step-by-step explanation:

(12*50)/100

If 12% of students of a class of 50 like blue  colour, the number of children that like blue is 6

The number of students in the class = 50

12% of the total number of students like blue

Number of students that like blue colour = 12% of 50

Number of students that like blue colour = (12/100)  x  50

Number of students that like blue colour = 0.12  x  50

Number of students that like blue colour = 6

Therefore, if 12% of students of a class of 50 like blue  colour, the number of children that like blue is 6

Then the conquistadores, few in number but courageous, conquered the Amerindian civilizations, which, for all their temples and gold, were evidently no more than paper tigers. . . . British, French, Dutch, and other European soldiers, merchants, and settlers did much the same thing in those parts of the New World not yet claimed by the Iberians. The history of the New World subsequently became the struggle of European imperialist powers for domination, and Amerindians ceased to be important. . . .[A new generation of historians, however, took] a fresh look at the origins of European imperialism, [examining] perhaps elements less dramatic than gold and God and heroes. . . . [According to these historians], in 1492 two systems, one of the Old World and the other of the New World, collided. The Old World peoples had some distinct advantages in the biological competition that followed. . . . The decisive advantage of the [European] invaders of America was not their plants or animalsand certainly not their muskets and rifles, which Amerindians eventually obtained in quantitybut their diseases. . . . These were the most lethal of the invaders of the New World in the sixteenth century.a) Based on the first paragraph, identify ONE argument made in the classic narrative of the Columbian encounter.b) Explain ONE development in the sixteenth century that would support the arguments of the new generation of historians in the second paragraph.c) Describe ONE way in which the biological competition referred to in the second paragraph contributed to European imperialism in the Americas.(I know its a lot but im using all my points I have just for this one question, thank you) Write an expression for "11 more than a."I Which of the following are examples of figures of speech?A. tone, variation, and feelingB. words, intensity, and moodC. hyperbole, metaphor, and idiomD. position, effect, and plot Graph from slope intercept form y=-1/3x+5
