Answer:

where's the diagram can you tell

Answer:

tricky ill be right back

Step-by-step explanation:

Answer:

From ages 5 to 8:

Pattern rule: Add 6 inches each year, since Fardad grows 6 inches each year.

Linear function:

[tex]y=6x+78[/tex]

From ages 8 to 10, not including 8:

Pattern rule: Add 11 inches each year, since Fardad grows 11 inches each year.

Linear function:

[tex]y=11x+38[/tex]

Step-by-step explanation:

Pattern rule seems subjective and I don't believe there is a technical mathematical term for it, but in terms of linear functions and patterns:

From ages 5 to 8: [tex]y=6x+78[/tex], where [tex]y[/tex] is Fardad's height after age [tex]x[/tex]

Pattern from ages 5 to 8: Fardad grows 6 inches each year (add 6 each year)

From ages 8 to 10, not including 8: [tex]y=11x+38[/tex], where [tex]y[/tex] is Fardad's height after age [tex]x[/tex]

Pattern from ages 8 to 10, not including 8: Fardad grows 11 inches each year (add 11 each year)

Answer:

a = 2

Step-by-step explanation:

Here, we want to get the value of a

From the remainder theorem, if we the divisor to zero and get a value for the variable, then substitute this value into the polynomial, the result we have is the remainder

So;

set x + 1 = 0 ; and x = -1

substitute this into the polynomial

(-1)^3 + 2(-1)^2 -5(a)(-1) -7

= -1 + 2 + 5a -7 = 5a -6

For the second;

set x -2 = 0; x = 2

Substitute in the second polynomial;

2^3 + a(2)^2 -12(2) + 6

= 8 + 4a -24 + 6 = 4a -10

So therefore;

2(5a-6) + 4a - 10 = 6

10a-12 + 4a -10 = 6

10a + 4a -22 = 6

14a = 6 + 22

14a = 28

a = 28/14

a = 2

Answer:

x = 23.5

Step-by-step explanation:

For a trapezoid, the angles on the same side are supplementary. This simply mean they add up to 180 degrees

thus, we have it that;

(6x + 3) + (x + 12.5) = 180

6x + x + 3 + 12.5 = 180

7x + 15.5 = 180

7x = 180-15.5

7x = 164.5

x = 164.5/7

x = 23.5

Answer:

See solutions below

Step-by-step explanation:

1) From the diagram QS = RS

3x = 2x+2

3x-2x = 2

x = 2

Since RS = 2x+2

RS = 2(2)+2

RS = 4 + 2

RS = 6

2) RQ = RS + QS

RQ = 2x+2 + 3x

RQ = 5x+2

RQ = 5(2)+2

RQ = 12

3) PQ = PR

3y-1 = y+5

3y-y = 5+1

2y = 6

y = 3

PQ = 3y-1

PQ = 3(3)-1

PQ = 8

4) PR = y+5

PR = 3+5

PR = 8

5) PQSR = PQ + QR

PQSR = 8 + 12

PQSR= 20

Answer:

yes

it's -14 I'm pretty sure my guy

Answer:

[tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes

Step-by-step explanation:

Wanda spends a third of her [tex]4\frac{1}{8}[/tex] hours studying math. Let us multiply these two fractions to find how much time she spent. Our first step would be to convert the mixed number into an improper fraction, as mixed numbers are hard to manipulate with:

[tex]4\frac{1}{8} =\\\frac{33}{8}[/tex]

Now let us multiply:

[tex]\frac{1}{3} *\frac{33}{8} =\\\frac{11}{8}[/tex]

If we wish, we can convert this into a mixed number:

[tex]\frac{11}{8}= \\1\frac{3}{8}[/tex]

or, 1 hour and 22.5 minutes.

Therefore, Wanda spent [tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes studying math.

I hope this helps! Let me know if you have any questions :)

Answer:

the last one is correct

Step-by-step explanation:

because 3000/12 = 250 and 3500/14 = 250 so they are porportional.

Answer:

D

Step-by-step explanation:

we'll use the complex number system to solve this exercice

the coordinates of the last triplet are : (1,2) , (2,4) and (4,8) The affixes are then

 [tex]1 + 2i = a \\2 + 4i= b = 2a \\4+8i = c = 2b = 4a[/tex]

for the points to be aligned the fraction [tex]\frac{c-a}{b-a}[/tex] should be a real number

[tex]\frac{c-a}{b-a} = \frac{4a-a}{2a-a} = \frac{3a}{a} = 3[/tex]

so the points are aligned

Answer:

Volume= l x w x h

Volume= 19 x 1.7 x 6

=193.8

1.7 feet to inches, 20.4 inches * 19 inches * 6 inches = 2,325.6cubic in, or 16.15 cubic feet

Answer:

Answer: b. Pure Imaginary Numbers.

Answer:

the anser is 40/8 that is 5

Answer:

ok from this we know the angle of this triange are

90+47+x=180

x=43

with these if we use the proper formula we know that the two other sides are

about 21 and 23

since the top side is longer we know that X=23

Answer:

(2x-3)(2x+1)

Step-by-step explanation:

4x^2 - 4x - 3

we need two numbers that give 12 when multiplied and 4 when subtracted

the numbers are 6 and 2 because 6*2=12 and 6-4=4.

4x^2 - (6-2)x -3

4x^2 -6x +2x -3

take common

2x(2x -3)+1(2x-3)

take (2x-3) as common

(2x-3)(2x*1 + 1*1)

(2x-3)(2x+1)

Answer:

the sum of the remaining exterior angles is 174⁰

Step-by-step explanation:

Given;

the measure of two exterior angles of a decagon = 97° and 89°

The total sum of exterior angles of a polygon is 360⁰

let the sum of the remaining exterior angles = x

sum of the given exterior angles = 97⁰ + 89⁰ = 186⁰

x + 186⁰ = 360⁰

x = 360⁰ - 186⁰

x = 174⁰

Therefore, the sum of the remaining exterior angles is 174⁰

Answer:

ok so if he pays 465.98 and we want to find the price if we reduce it by 3.6 we can multiple it by

465.98*0.964=

449.20472

so now we round to two points to get

449.21

Answer:

3,680 cubic feet

Step-by-step explanation:

The volume of a rectangular prism is:

length x width x height

Rooms are in the shape of a rectangular prism, so the figure we are gonna tind the volume of is a prism.

The volume of Mr. Tai’s living room is:

10 x 18 x 8 = 1,440 cubic feet

The volume of his family room is:

14 x 20 x 8 = 2,240 cubic feet

Add the volumes of both figures:

1,440 + 2,240 = 3,680

Step-by-step explanation:

The question is incomplete, as the box plot is not given. A general approach to the question, is as follows:

First, identify the 27 mark on the box plot.

Next, count the number of data less than 27.

Take, for instance, there are 6  dots or marks before 27;

This means that 6 bags contain  less than 27 ounces

have a good day :)

Step-by-step explanation:

Answer:

51/28 or 1 23/28

Step-by-step explanation:

The LCD here is 9.  Rewrite 5 2/3 first as 17/3, and then multiply numerator and denominator both by 3, obtaining the equivalent 51/9.

Then divide 51/9 by 28/9:  Equivalently, invert the divisor (28/9) and multiply:

(51/9)(9/28) = 51/28 or 1 23/28

5 2/3 divided by 3 1/9 is 1 23/28.

Answer:

y = 0.75x + 12

Step-by-step explanation:

The estimated total cost, y, of a child's toy is partially based on the number 1 point of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?

y = 12x + 0.75

y = 0.75x + 12

y = 12x − (775

y = 0.75x − 12

y = total cost of a child's toy

Cost of each battery = $0.75

Number of batteries = x

Cost of the toy = $12

Therefore,

total cost of a child's toy = Cost of the toy + Cost of each battery * Number of batteries

y = 12 + 0.75 * x

y = 12 + 0.75x

y = 0.75x + 12
