Answer:

Route A is 0.75 km longer than route B.

Step-by-step explanation:

Length of route A is 1.5 times the length of route B.

a = 1.5b

[tex]\frac{a}{b}=\frac{15}{10}[/tex]

[tex]\frac{a}{b}=\frac{3}{2}[/tex] --------(1)

Here, a = Length of route A

b = Length of route B

Length of route A is [tex]\frac{3}{4}[/tex] of route C.

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

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

Here, c = Length of route C

Length of route C = 3 km

Length of route A = [tex]\frac{3}{4}\times 3[/tex] [From equation (2)]

                             = 2.25 km

Length of route B = [tex]\frac{2}{3}\times 2.25[/tex] [From equation (1)]

                             = 1.5 km

Difference in route A and route B = 2.25 - 1.5

                                                       = 0.75 km

Therefore, route A is 0.75 km longer than route B.

Answer:

32 ounces

Step-by-step explanation:

8x4=32

There are 32 ounces of stuffing in 4 of the pillow.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A pillow contains 8 ounces of stuffing.

Now,

Since, A pillow contains 8 ounces of stuffing.

So, The amount of ounces in 4 of the pillow = 8 x 4

                                                                    = 32

Thus, There are 32 ounces of stuffing in 4 of the pillow.

Answer:

six out of the fifteen are apples

Answer:

1,296

Step-by-step explanation:

The answer is 1,296 because the numbers are going in the order of powers:

6^1 = 6

6^2 = 36

6^3 = 216

6^5 = 7,776

6^6 = 46,656

The power that is missing is 6 to the 4th power, which, when calculated, would be 1,296.

So, the answer would be 1,296

Answer:

50.29 cm²

Step-by-step explanation:

Base area of a cylinder = πr²

π = 22/7

r = radius

For circular objects, the width is the same as the diameter of the object

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

radius = 8/2  = 4cm

Base area = (22/7) x 4² = 50.29 cm²

Answer:

Refer the digram & explanation.

Step-by-step explanation:

GIVEN :-

TO PROVE :-

CONSTRUCTION :-

FACTS TO KNOW BEFORE SOLVING :-

PROCEDURE :-

∠QPR + ∠QOR = 180°

⇒ ∠QOR = 180° - ∠QPR

In ΔQOR , OQ = OR (∵ Radii of the circle are equal)

⇒ ΔQOR is an isosceles triangle (∵ OQ = OR i.e. two sides of the triangle are equal.)

⇒ ∠OQR = ∠ORQ (∵ In an isosceles triangle , the base angles are equal)

So,

∠QOR + ∠OQR + ∠ORQ = 180°

⇒ ∠QOR + 2∠OQR = 180°  (∵ ∠OQR = ∠ORQ)

⇒ 180° - ∠QPR = 180° - 2∠OQR  (∵ ∠QPR + ∠QOR = 180°)

⇒ -∠QPR = -2∠OQR  (∵ Cancelling 180° from both the sides.)

⇒ ∠QPR = 2∠OQR (Proved)

Accοrding the given question "Jοhn wished him well" is a fragment. Thus,  the correct answer is F.

A fragment differs frοm a complete sentence because fragments do not express a complete idea οr include both a subject and a verb that are necessary for a sentence, instead fragments tend tο include only a subject or only a verb alοng with other words that complete them.

In the case of "Scurried acrοss the field" this item is a fragment (F) because it cοntains the main verb "scurried" that means to rush alοng with other wοrds that complete the meaning οf the verb "across the field" but it dοes not contain a subject or specifies who or what was hurrying.

Answer:

y = (1/3)x + 7

y = (1/3)x - 15

These are two examples out of an unlimited number of possibilities.

Step-by-step explanation:

The slope of this given line is -3.  Any new line perpendicular to this one is the negative reciprocal of -3:  1/3.

The slope-intercept form is y = mx + b.  Here m = 1/3, so the revised form is

y = (1/3)x + b.

Two straight lines perpendicular to the given line are easily found by selecting two different values for b:

y = (1/3)x + 7

y = (1/3)x - 15

Answer:

y = -x - 7.9

Step-by-step explanation:

Given:

m = -1

b = -7.9

y = mx + b

y = -x - 7.9

Answer is D:  rational number

Step-by-step explanation:

The given number is the element of the set of rational numbers. option D is correct.

Given that,
A list of 5 numbers is shown below. 0, 3, 7, -6, -12.3, which set contains all the numbers in the list is to be determined.

In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.

An irrational number is a type of real number which cannot be represented as a simple fraction or the values that have face value are irrational numbers. Example: √2, √3, and π are all irrational.

Here,
Since the number are of negative and contain such as -12.3 thus these all belong to the set of rational numbers.

Thus, the given number is the element of the set of rational numbers.

Given data

Rate= 8%

Time= 8years

Simple interest= $800

Required

The principal P

We know that the expression for simple interest is given as

SI=PRT/100

substitute

800= P*8*8/100

cross multiply

800*100= 64P

80000=64P

divide both sides by 64

P= 80000/64

P=$1250
