Answer:

In romania I was doing this in the 6th grade

Step-by-step explanation:

5.

A B and D C are parallel lines.

"slope" means inclination. and as you can imagine, parallel lines must have the same inclination, or they would not be parallel.

so, the slope of D C must be also 2/7.

4.

same thing as with 5.

both lines are parallel and must therefore have the same slope.

so, the slope of D C is also 3/4. and the first answer is correct.

Answer:

-3/4

Step-by-step explanation:

Problem

-1 1/4 + 1/2

Comment

This combined with the number line is to help you visualize how fractions can be represented and how you find their sum.

The rule is move left when the number is minus. Move right when the number is plus.

so -1 1/4 = (4*-1   -1 )/4 = - 5/4

Start at 0 and move left. The number beside - 1 on the number  line is -5/4 Put an arrowhead on the line you just drew. The arrowhead should be just about -5/4.

Each mark on the number line is 1/4 away from the next quarter on the number line.

1/2 = 2/4

So since 1/2 is plus, you move right. You need 2 marks right of -5/4. You will find that is at -3/4

Answer:

Option (D) is correct.

Shyla spend $30.94 on the fabrics

Step-by-step explanation:

Shyla has a box with the dimensions of 7 inches, 11 inches, 8 inches. Since it has 3 sides thus, it is form of a cuboid.

Here Length (l) = 7 inches

Breadth (b) = 11 inches

Height (h) = 8 inches

Surface area of Cuboid = 2( lb +bh + hl )

Substitute the values, we get,

Surface area of Cuboid = 2( 7 × 11 + 11× 8 + 7 × 8 )

                                       = 2( 77 +88 +56)

                                       = 422 square inches.

Given: the fabric costs 7 cents per square inch = $0.07 per square inches.

Money  Shyla spend on the fabric = total area × cost of fabric per square inch

                                                      = 442 × 0.07

                                                      = $30.94

Thus,  Shyla spend $30.94 on the fabrics.

So , Option (D) is correct.

Answer:

8/12

Step-by-step explanation:

Answer:

Step-by-step explanation:

the bars, |   |, mean absolute value

for example, if it was

| -9 |

then it would be 9

if it was

| 9 |

then it would be 9

if it was

| -550 |

it would be 550

you take the number, and if its negative, then it becomes positive

Answer:

  a)  £10.50

  b)  £5.40

Step-by-step explanation:

In this context, "of" means "times".

__

  1/4 × £42 = £(42/4) = £10.50

__

  2/5 × £13.50 = £(2·13.50/5) = £(27/5) = £5.40

_____

Additional comment

The symbol "£" is a currency symbol identifying the units of the associated number. For algebraic purposes, any symbol representing units can be treated as though it were a variable.

In this question of means multiplication.

Let us start solve this question

Question 1

[tex] \small\rm{ \dfrac{1}{4} \: of \: £ \: 42}[/tex]

First we will convert whole number into a fraction

(Any number can be converted to fraction if you use 1 as the denominator)

[tex] \small\sf{ \dfrac{1}{4} \: \times \: \dfrac{42}{1}}[/tex]

Now we will multiply the numerators and denominators.

[tex] \small\sf{ \dfrac{42}{4} = £10.50 } [/tex]

Question 2

[tex] \small\rm{\dfrac{2}{5} \: of \: £ \: 13.50}[/tex]

First we will convert whole number into a fraction

[tex] \small\sf{ \dfrac{2}{5} \times \dfrac{13.50}{1} } [/tex]

Now we will multiply the numerators and denominators.

[tex] \small\sf{ \dfrac{27}{5} =£ 5.40 } [/tex]

Analyzing the information, it is clear that to find the solutions of the problems it is necessary to perform the calculation of mathematical arrangements.

Correspond to a case of permutations, they are groupings that are formed with a number p of elements from a set of n elements. The elements of p must occupy ordered positions, where p ≤ n. The formula is:

So, to solve the problems we do the following calculations:

A) 2^n =

2^8 = 256

B) We must pay attention to the statement, which asks for the minimum number of condiments required to prepare 1000 different sandwiches, so:

2^n [tex]\geq[/tex] 1000

n = 3

2^3 = 8

Answer:

One of the practical situation of geometric series is : A ball bouncing is an example of a finite geometric sequence. Each time the ball bounces it’s height gets cut down by half. If the ball’s first height is 4 feet, the next time it bounces it’s highest bounce will be at 2 feet, then 1, then 6 inches and so on, until the ball stops bouncing

Answer:

Geometric series are seen in practical situations, most notably in those involving geometric growth or decay. If a series of numbers are formed by percentages, then it can result in a geometric sequence. Ex. compound interest (see below).

Step-by-step explanation:

A geometric series is the result of adding the terms of a geometric sequence. These sequences have a common ratio, r, which is used to find missing terms. The common ratio is found with [tex]r=\frac{a_n}{a_{n-1}}[/tex]. For example, [tex]a_1(r)=a_2, \mbox{ and } a_2(r)=a_3... \mbox{ etc.}[/tex]

Geometric sequences can be used to model practical situations, and such situation could involve geometric growth or decay.

A geometric sequence can be used to model compound interest. An example of this is [tex]A = P (1 + \frac{r}{100})^n[/tex] where the common ratio, r, of the series is equal to 1 + r/100 in the compound interest formula above.

Step-by-step explanation:

1.5% of 800 is 12

Answer:

The relation is reflexive as

(1,1),(2,2),(3,3)∈R

(2,1)∈R will not imply (1,2)∈R,

hence R is not symmetric

(2,1),(1,3)∈R doesn't imply (2,3)∈R, hence R is not transitive
