Answer:

3.06 meters

Step-by-step explanation:

The first thing you want to do, since we are working with different units here, is find out how many centimeters make a meter... and so on.

1cm = 0.01m

1mm = 0.001m

123cm = 1.23m (Dressing table)

410mm = 0.41m (Cupboard door)

Now all we need to do is subtract.

We can add the two numbers together or (If you prefer) subtract separately.

1.23 + 0.41 = 1.64

Now subtract that number from the measurement of the wall:

4.7 - 1.64 = 3.06

The amount of space left is 3.06m.

Answer: 5 days.

Step-by-step explanation: To solve this problem, we first need to convert 1 7/10 bags of tortillas to a decimal number. We can do this by dividing the numerator of the fraction (7) by the denominator (10) and adding the result to the whole number (1) to get 1 + 7/10 = 1.7 bags of tortillas.

Next, we can divide the number of bags of tortillas that Garrett's burrito stand uses per day (1.7 bags) into the total number of bags of tortillas that are available (8.5 bags) to find out how many days the tortillas will last: 8.5 bags / 1.7 bags/day = 5 days

Therefore, the 8 1/2 bags of tortillas will last for 5 days.

1. (x + 2) = 0  gives us x = -2 = x coordinate of vertex; and

  the -1 at the end gives us the y coordinate.

  Move the vertex of the parabola to the point (-2,-1)

2. The -4 in front of the (x+2)² gives the direction and stretch of the parabola. FROM the Vertex, position the other point Down 4 and Right 1 (at (1,-5)).

Answer:

Step-by-step explanation:

443

Answer: D

Step-by-step explanation:

The parent function abs(x) is a V, similar to graph B.

When it is multiplied by a negative number then it reflects across the Y axis, and if the number is greater than 1, then the graph is horizontally compressed (like you're squishing the sides together, closer to each other).  If the number is less than 1, either decimals or a fraction, then it is stretched (like you are pulling the sides away from each other and they are getting wider).  

In this case you are multiplying abs(x) by 4, which is greater than 1 so it is compressed by a factor of 4, and then multiplying it by a negative, which reflects it across the y axis.

Irrational

Step-by-step explanation:

A rational number can be expressed as p/q where p and q are integers

3.04 is rational since it can be expressed as 304/100

√20 is not rational. √20 = √(4·5) = √4·√5 = 2√5
While 2 is a rational number, √5 is irrational since 5 is a prime number and square roots of primes are not rational

An irrational number multiplied by a rational number is irrational so √20 is irrational

An irrational number added to a rational number results in an irrational number.

So 3.04 + √20  is irrational

Correct answer is:

27

Answer:

There would be 27 ounces of flour

Step-by-step explanation:

The ratio is 7:3 for sugar to flour.

I divided the 63 ounces of sugar by 7 to earn 9

Now, I multiplied 9 by 3 to get 27

Now thee ratio is 63:27

If you divide 7 and 3 you will get 2.3 repeating

If you divide 63 and 27 you will also get 2.3 repeating

The base of the original triangle is 12 centimetres.

A triangle is a polygon with three sides. The perimeter of a triangle is 58 cm. The triangle is isosceles.

An isosceles triangle is a triangle with 2 sides equal to each other and two angles equal to each other.

Therefore, let's find the base of the original triangle when the base were lengthened by 4 cm and each leg were shortened by 7 cm,

Hence,

let

x = length of legs

y = length of the base

Therefore,

2x + y = 58

Hence,

y + 4 = x - 7

x - y = 11

2x + y = 58

x - y = 11

3x = 69

x = 69 / 3

x = 23

-y  = 11 - 23

-y = -12

y = 12

Therefore,

base of the original triangle = 12 cm

The number of each type of shirt ordered are as follows;

Old Navy had $940 worth of orders for shirts.

The prices for the shirts were categorized by style: $10 for tank tops, $14 for graphic tees, and $22 for polos.

The number of polos ordered was one more than half the number of graphic tees, and the number of graphic tees ordered was eight less than twice the number of tank tops.

let

x = number of graphic tees

Hence,

number of polos = 1 + 1 / 2 x

Number of tank tops = 1 / 2 x + 4

Therefore, the total

14x + 10(1 / 2 x + 4) + 22(1 + 1 / 2 x) = 940

14x + 5x + 40 + 22 + 11x = 940

30x + 62 = 940

30x = 878

x = 29.266667

x = 29

number of polos = 1 + 1 / 2 (29) ≈ 15

Number of tank tops = 1 / 2 (29) + 4 ≈ 19

The distance between us and a star with a parallax angle of 0.0001 arcsecond is 32600 light years.

The distance at which an object has a parallax of 1 arcsecond is known as a parsec. 3.26 light years are about how far this is.

The length of one parsec is 3.26 light years.

One arcsecond is equal to one parsec, which is equal to 3.26 light years.

We determine the other provided arcseconds based on this comparison.

3.26 light years make up a parsec.

0.1 arcsecond = 10 parsec

= 10 * 3.26 light years

= 32.6 light years

Step-by-step explanation:

Answer:

Volume = 282.6 ft.²

Step-by-step explanation:

Volume: V = πr²h

Step 1: The answer needs to be in cubic feet, so convert all units to feet

    1. 3 ft./12 in. = 0.25 ft.

Step 2: Subtract 0.5 ft from 6.5 ft to find the actual diameter of the pipe that the water will be passing through

    2. 6.5 ft. - 0.5 ft. = 6 ft.

Step 3: Plug 3 ft. (radius), 3.14 for π, and 5 ft for h

    3. V = (3.14)(3 ft.)²(5 ft.)

Step 4: Solve for the V (volume)

    4. V = (3.14)(9 ft.)(5 ft.) → V = (28.26)(5) → V = (28.26)(5) → V = 141.3 ft.²

Step 5: Divide 141.3 by 2, since we want half the capacity

    5. 141.3 ft.²/2 = 70.65 ft.²

Step 6: Multiply 70.65 by 4 since we want the total volume of water passing through four pipes

    6. 70.65 ft.² ∙ 4 = 282.6 ft.²

Answer:

8700kg

Step-by-step explanation:

b = mass of bricks

l = mass of lorry

b+l = total mass = 11600kg

b = 3l  ==>  l = b/3

substitute: b + b/3 = 11600

multiply every term by 3 to get rid of denominator: 3b + b = 34800

simplify and solve:  4b = 34800  ==>  b = 8700

check:  l = 8700/3 = 2900

2900 + 8700 = 11600?  YES

What is the area of the rectangle?

When calculating a rectangle's area, we multiply the length by the width of the rectangle.

we have,

length = 40ft

width = 10ft

Leila's vegetable garden has an area of 400 ft.

a)

new length = 40 * 2 =80ft

new width = 10 * 4 = 40ft

Therefore,  this describes the size of Leila's new garden :

= 80 * 40 = 3200ft²

b)

3200 / 400 = 8

The expansion changes the area of the garden:

The area of the new garden will be 8 times the area of the current garden.

c)

Leila's friend Keiko wants to expand her rectangular garden by 20 times the area of her current garden:

400 * 20 = 8000ft²

Keiko's garden length would be  5 times the current length:

40 * 5 = 80ft

and the new width would be the current width :

new width of Keiko's garden = 8000 / 80 = 100ft.

Hence, the answers of all the blanks are as:

a) 3200ft².

b)  8 times.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.

Given that;

During a test, 3 out of 100 cars selected at random were found to be defective.

Now,

Since, During a test, 3 out of 100 cars selected at random were found to be defective.

Let number of defective cars if 1,500 cars are tested = x

So, By definition of ratio, we get;

⇒ 3 / 100 = x / 1,500

Solve for x as;

⇒ 3 × 1500 / 100 = x

⇒ 3 × 15 = x

⇒ x = 45

Thus,  There are 45 defective cars if 1,500 cars are tested.

First, we want to deal with the parenthesis within the parenthesis.

(4.6/2) = 2.3

Rewrite it into the equation.

[3 * 2.3] + 14.1 = ?

Now, do the work in the parenthesis again.

[6.9] + 14.1 = ?

There isn't anymore parenthesis, exponents, or multiplication/division, so we move onto addition now and add both terms.

6.9 + 14.1 = 21

? = 21
