Answer:

niamah : jack

2 : 5

2×3 : 5×3

6 : 15

niamah gets 6 pencils

jack gets 15 pencils

*6+15 = 21

Answer:

Step-by-step explanation:

If the ratio of Niamah to Jack is 2:5, that means that for every 2 pencils that N gets, J gets 5. If there are a total of 21 pencils, then

2x + 5x = 21 and

7x = 21 so

x = 3.

That means that N gets 2(3) which is 6, and J gets 5(3) which is 15. Notice that 6:15 is the same ratio as 2:5 when it is reduced.

Answer:

20

Step-by-step explanation:

The triangles are similar so we can use ratios

8       32

---   = -----

8+5    32+x

Using cross products

8(32+x) = 32(13)

Divide each side by 8

(32+x) = 32(13)/8

32+x = 4*13

32+x =52

Subtract 32

x = 20

y = 6x + 1

Step-by-step explanation:

Use the point slope equation:

y - y1 = m( x - x1 )

y - 1 = 6 ( x - 0)

y - 1 = 6x

y = 6x + 1

Answer: the correct answer is -8

Step-by-step explanation:

Substitute the given value of m into the expression:

-4|5 + (-3)|.

Then evaluate using the order of operations:

-4|5 + (-3)|

= -4|2|

= -4(2)

= -8

Substitute the given value of m into the expression:

-4|5 + (-3)|.

Then evaluate using the order of operations:

-4|5 + (-3)|

= -4|2|

= -4(2)

= -8

The first step in evaluating an expression is to substitute the given value of a variable into the expression. Then you can finish evaluating the expression using arithmetic.

A variable is a letter, for example, x, y, or z, that represents an unspecified number. To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.

Answer: b) rotation of 180°, reflection across y-axis

Step-by-step explanation:

The black triangle is in Quadrant IV.

A rotation of 180° will move it to Quadrant II.

The red triangle is in Quadrant I so  you must reflect it across the y-axis.

Answer:

(10x + 37) and (15x+7) are vertical angles which are always equal

10x + 37 = 15x +7

5x = 30

x = 6

The angle (15x +7) equals 97 and the other angle (10x + 37) also equals 97 degrees.  All 4 of the angles add up to 360 degrees.

Therefore, 360 = 2z + 97 + 97

2z = 166

z = 83

Step-by-step explanation:

Answer:

135 degree

Step-by-step explanation:

total sum of angle = (8-2) * 180 = 1080

each angle = 1080/8 = 135 degree

There are four 10 cards in the deck, so P(10) = 4/52 = 1/13

P(not 10) = 1 - P(10). This is because the maximum probability is 1, and the card you draw will either be 10, or not a 10.

P(not 10) = 1 - 1/13 = 13/13 - 1/13 = 12/13

Answer:

(5,6), (3, 6) and (3, 5).

Step-by-step explanation:

If we imagine the line y = x to be a mirror , the image of each point is the same perpendicular distance to the mirror has the original point.

So the image of (6,5) = (5,6)

(6, 3) ---> ( 3, 6)

(5,3) ---> (3, 5).

Note that the coordinates are reversed in each case.

In this case the general rule for the reflection is  (x, y)  ---> (y, x).

Answer:

20. 13 cm

21. 12 cm

Step-by-step explanation:

20. isosceles means two sides are the same length, so you take the ten off the perimeter to get 26 remaining cm (36 -10) and you then divide that by two to get both sides of 13 cm (26 / 2)

21. because you know that if you split the triangle down the middle you get a right triangle and you can use a^2+b^2=c^2 to find the height, so we take the one side of 13 cm and half of the third side, which is 5, and you can find your answer (a^2 + 5^2 = 13^2   ---> a^2 + 25 = 169 ---> a^2 = 144 ---> a = 12)

1:     7200/24 = x/1

2:    7200/24 = 300/1

3:     300 L of blood per hour

We know that an average is 7200 for heart pumps so we divide 7200 by 24 hours = x/1  

Second step is the same 7200 divided by 24 = 300/1

So the correct answer is 300. 300 L of blood per hour.

The rate of change in the volume of blood is 300 liters per hour.

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

The volume of blood pumped by the teenager's heart is expressed as a rate of change in volume per hour.

Rate of change of volume of blood = volume of blood/time

= 7200 L /24

Apply the division operation, and we get

= 300 L/hour

The teenager's heart changes blood volume at a pace of 300 liters per hour. This means that his or her heart is pumping 300 liters of blood every hour.

Surface area of the triangular prism is 96 feet.

The area of a three dimensional object on it's outer surface is called the surface area of the object.

A triangular prism has 2 triangular bases and 3 rectangular lateral faces.

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

There are 2 triangles at the top and bottom.

Here base = 3 feet and height = 2 feet

Total surface area on the top and bottom = 2 × [tex]\frac{1}{2}[/tex] × base × height

                                                                     = base × height

                                                                     = 3 × 2

                                                                     = 6 feet

There are 3 rectangular faces.

Area of the rectangle = Length × width

Here, length = 10 feet and width = 3 feet

Area of the rectangular face = 10 × 3 = 30 feet

Since there are 3 rectangular faces,

Total lateral surface area = 3 × 30 = 90 feet

Total surface area of the triangular prism = 90 + 6 = 96 feet

Hence the total surface area of the given triangular prism is 96 feet.

Perpendicular: [tex]y = \frac{5}{8}x+4[/tex]

Parallel: [tex]y=-\frac{8}{5} x+RandomNumberNot4[/tex]

Step-by-step explanation:

I'm going to rewrite the equation:

[tex]y=-\frac{8}{5} x+\frac{4}{5}[/tex]

Perpendicular means that the slope is the opposite reciprocal.

Slope = [tex]\frac{5}{8}[/tex]

[tex]y = \frac{5}{8}x+4[/tex]

Parallel means that the slope is the same but the y - intercept is different:
