Step-by-step explanation:

Considering the equation is;

-4x (less than or equal to ) 36 , as provided by the questioner;

-4x ≤ 36

Dividing both sides by -4

-4x/-4≤ 36/-4

We get;

x ≥ -9 , the sign ≤ changes to ≥ since we have divided by a negative.

Answer: 55

Step-by-step explanation: The inside measure of a triangle should be 180 so knowing this subtract 43 and 82 and you get 55.

In the given triangle ∠E = 55° and side EF = 12.49 unit

As we know the sum of all three angles in a triangle is 180°

so ∠E = 180-43-82 = 55°

In a triangle ABC if BC = a, AC = b, AB = c

then [tex]\frac{Sin A}{a} = \frac{sin B}{b} = \frac{SinC}{c}[/tex]

From sine rule,

[tex]\frac{sin 43}{EF} = \frac{Sin 55}{15}[/tex]

[tex]EF = 15* \frac{Sin43}{Sin55}[/tex]

EF = 12.49

Therefore, in the given triangle ∠E = 55° and side EF = 12.49 unit

The pitch of the roof is 9/7

This question clearly states that it is a 'find the volume' question.

Given dimensions of the object are :

Length of the object = [tex]40\frac{1}{2}[/tex] inches or 40.5 inches

Depth of the object = 10 inches

Height of the object is = 8 inches

So, the volume becomes = [tex]40.5\times10\times8[/tex] = 3240 cubic inch

Hence, the amount of cement needed is 3240 cubic inches.

To fill the form, you use the formula for the volume of a rectangular prism (length x width x height) to find that 3240 cubic inches of cement is needed.

The student is asking about the volume of cement needed to fill a form with specified dimensions. To calculate the volume, we need to use the formula for the volume of a rectangular prism, which is length x width x height. In this case, we need to convert the mixed number into an improper fraction before multiplying, or we could convert it to a decimal.

First, convert the length from 40 1/2 inches to 40.5 inches. Then, use the formula:

Volume = length x width x height

Volume = 40.5 in x 10 in x 8 in

Volume = 405 in x 8 in

Volume = 3240 cubic inches

Therefore, to fill the form, 3240 cubic inches of cement is needed.

Johnny currently owns fewer than 200 records.

Let's denote:
- \( x \) as the number of records Johnny currently owns.

Given:
- Gina has 400 records.
- Johnny would still have fewer than Gina has if he were to double the number of records he owns.

We can set up the following inequality:

[tex]\[ 2x < 400 \][/tex]

To find the maximum value of \( x \), we solve for it:

[tex]\[ x < \frac{400}{2} \]\[ x < 200 \][/tex]

So, Johnny currently owns fewer than 200 records.

Answer:

NO

Step-by-step explanation:

To find if they are equivalent, we need to simplify them first.

Using the distributive property we get:

6(4x-5) = 24x - 30

In this case we need to combine like terms.

3 + 22x - 33 - 2x =  20x - 30

So now we can compare.

24x - 30 ≠ 20x - 30

So we can conclude that the two expressions are not equal because 24x - 30 and 20x - 30 are obviously not equal.

Answer:

Not equivalent

Step-by-step explanation:

We are given an expression [tex] 6 ( 4 x - 5 ) [/tex] and we are to check if it is equal to [tex] 3 + 22 x - 33 - 2 x [/tex] or not.

Evaluation the given expression first:

[tex] 6 ( 4 x - 5 ) = 24 x - 30 [/tex]

While adding the terms in [tex] 3 + 22 x - 33 - 2 x [/tex], we get:

[tex] 22 x - 2 x - 33 + 3 = 20 x - 30 [/tex]

[tex] 24 x - 30 \neq 20 x - 30 [/tex]

Therefore, [tex] 6 ( 4 x - 5 ) [/tex] is not equivalent to [tex] 3 + 22 x - 33 - 2 x [/tex].

f(0) equals 0. When x is 0 in the given function, the result of f(x) is also 0.

To find the value of f(x) when x=0 for the function f(x) = -1x, substitute 0 for x:

f(0) = -1(0) = 0.

Therefore, f(0) equals 0. When x is 0 in the given function, the result of f(x) is also 0.

Answer:

Step-by-step explanation:

Darren completely filled each box before the 21st box.  This means he completely filled 20 boxes.  To find out how many tins fit in each box, divide:

496/20 = 24.8

This means each of the 20 preceding boxes held 24 tins.  To get these filled, Darren used 20(24) = 480 tins of juice.

This left Darren with 496-480 = 16 tins of juice to put in box 21 before lunch.

Final answer:

To find out how many tins are in box 21, we subtracted the number of tins contained in the first 20 fully packed boxes from the total number of tins Darren packed. We found that each of the first 20 boxes must contain 24 tins, hence, there are 16 tins in the partially filled box 21.

Explanation:

The student's question is about finding how many tins were in box 21 before Darren stopped for lunch. To determine this, we need to figure out the pattern of how the tins were packed into the boxes. Since Darren packed the 496th tin in box 21, and since box 21 is not completely full, we can start by assuming that each box before box 21 was filled completely. If we can find the number of tins each box can hold, we will know the number of tins in box 21.

Let's assume the number of tins each box can hold is x. Since 20 boxes are completely full, they would contain a total of 20x tins. Box 21 contains fewer than x tins. The total number of tins, including those in box 21, is 496. Thus, we have the equation 20x + (496 - 20x) = 496. Simplifying, we get 20x = 496 - (496 - 20x), leading to 20x = 20x, which means each of the first 20 boxes contains the same number of tins. To find x, we need to divide the total number of tins not including box 21 by 20. Now we subtract that product from 496 to find the number of tins in box 21.

Since 496 is not evenly divisible by 20, we find that x is a decimal, which is not possible since we cannot have a fraction of a tin. Therefore, we subtract 1 from 496 to make it divisible by 20, giving us 495 tins to be divided evenly among the 20 full boxes. So, 495 ÷ 20 = 24.75, which means each full box holds 24 tins (since we can't have a fraction of a tin). Therefore, the number of tins in box 21 is 496 - 20*24 = 496 - 480 = 16 tins.

Final answer:

The density of the laptop is calculated by dividing the mass (2,300 grams) by the volume (2,850 cubic centimeters), resulting in a density of 0.807 g/cm³, which is approximately 46/57.

Explanation:

To find the density of the laptop in grams per cubic centimeter (g/cm³), we use the formula density = mass/volume. The mass of the laptop is given as 2,300 grams and the volume is given as 2,850 cubic centimeters. By substituting into the formula:

Density = Mass / Volume = 2,300g / 2,850cm³ = 0.807 g/cm³.

When expressed as a fraction in simplest form, this is approximately 46/57 (since 0.807 ≈ 46/57). Hence, the answer is D. 46/57.

Answer:

KT = 60

OY = 11

Step-by-step explanation:

Remember that the tangent to a circle theorem states that if a line is tangent to a circle, it is perpendicular to the radius at the point of tangency. Which means angles OTK and OYK are right angles.

If OTK and OYK are right angles, triangles KOT and KYO are right triangles. Since KOT is a right triangle, we can use the Pythagorean theorem to find KT:

[tex]hypotenuse^2=leg^2+leg^2[/tex]

[tex]KO^2=KT^2+OT^2[/tex]

[tex]61^2=KT^2+11^2[/tex]

[tex]KT^2=61^2-11^2[/tex]

[tex]KT=\sqrt{3600}[/tex]

[tex]KT=60[/tex]

Now, remember that the "hat" theorem states that tangents to a circle from the same external point are congruent, so KT and KY are congruent.

The Hypotenuse-Leg theorem states that if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg another right triangle, then the triangles are congruent. The hypotenuse, KO, of both right triangles are the same (therefore congruent) and legs KT and KY are congruent by the hat theorem, therefore triangles KOT and KYO are congruent. Since corresponding parts of congruent triangles are congruent, OY ≅ OT.

OY = OT = 10

OY = 10

Let's summary the above in a short proof:

2. ΔOTK and ΔOYK are ∟ triangles   Definition of right triangles

3. KT ≅ KY                                             Hat theorem

Answer:

43°

Step-by-step explanation:

From the diagram

∠xwy=∠xyw = isosceles triangle where base angles are equal

∠y= ∠w = (180-86)÷2 = 47°

if ∠xzy=90° and ∠xyz =47° then ∠d=?

∠d= 180°-(90°+47°)

∠d=180°-137° =43°

Answer:

x = 15; m<(3x) = 45; m<(2x + 15) = 45

Step-by-step explanation:

The measures of the angles measuring 3x and 2x + 15 add up to 90 degrees.

3x + 2x + 15 = 90

5x + 15 = 90

5x = 75

x = 15

m<(3x) = 3 * 15 = 45

m<(2x + 15) = 2 * 15 + 15 = 30 + 15 = 45

Answer:

(-1, -1) Let me know if the explanation didn't make sense.  

Step-by-step explanation:

If we graph the three points we can see what looks like a quadrilateral's upper right portion, so we need a point in the lower left.  This means M is only connected to N here and P is only connected to N.  So we want to find the slope of these two lines.

MN is easy since their y values are the same, the slope is 0.

NP we just use the slope formula so (y2-y1)/(x2-x1) = (-1-3)/(5-4) = -4.

So now we want a line from point M with a slope of -4 to intersect with a line from point P with a slope of 0.  To find these lines  weuse point slope form  for those two points.  The formula for point slope form is y - y1 = m(x-x1)

y-3 = -4(x+2) -> y = -4x-5

y+1 = 0(x-5) -> y = -1

So now we want these two to intersect.  We just set them equal to each other.

-1 = -4x -5 -> -1 = x

So this gives us our x value.  Now we can plug that into either function to find the y value.  This is super easy of we use y = -1 because all y values in this are -1, so the point Q is (-1, -1)

Step-by-step explanation:

Let "e" represent the number of pounds of Earl Grey tea required for the mix. Then (600-e) is the number of pounds of Orange Pekoe tea required. The total cost of the mix is ...

  6·e + 4·(600 -e) = 4.50·600

  2e = 600·(4.50 -4.00) . . . . . simplify, subtract 4·600

  e = 300/2 = 150 . . . . . . . . . . divide by the coefficient of x

Required are 150 pounds of Earl Grey and 450 pounds of Orange Pekoe.

The amount of Earl Grey and Pekoe tea required for the new blend is :

Price of new blend per pound = $4.50

Price per pound of Earl tea = $6

Price per pound of Pekoe tea = $4

Let :

Pound of Earl tea = a

Pound of Pekoe tea = b

Converting the information to Mathematical expressions :

From (1):

a = 600 - b

Put a = 600 in (2)

6(600 - b) + 4b = 2700

3600 - 6b + 4b = 2700

Collect like terms :

-6b + 4b = 2700 - 3600

-2b = -900

b = 900 ÷ 2

b = 450

What are mathematics operations?

A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Here, it is given that :

Ellie read 30 pages of her social studies book in 1.5 hours at a constant rate, let first find Ellie's social studies reading rate :

rate = 30 pages/1.5 hours = 20 pages/ hr.

Now, to find out the unit rate, divide the total number of pages reading novel by the total time spent.

rate = 150 pages/ 2 hours = 75 pages/ hr.

To find out the percentage divide Ellie's novel reading rate by  Ellie's social studies reading rate and multiply by 100

percent of Ellie’s social studies reading rate is her Novel reading rate = 75/20 x 100 = 375%.

Therefore, percent of Ellie’s social studies reading rate is her Novel reading rate is 375%.
