Answer:

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction and division. The result of a multiplication operation is called a product. And division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication

Answer:

472.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Base (b) = 30 yd

height (h) = 31.5 yd

Area of the triangle

= 1/2 * b * h

= 1/2 * 30* 31.5

=472.5 yd²

Answer:

11:60

Step-by-step explanation:

In ΔHIJ, given the measure of ∠J=90°, JI = 48, IH = 73, and HJ = 55. We are to find tan<H

Using SOH CAH TOA

tan theta = opposite/adjacent

JI is the opposite (facing m<H)

HJ will be adjacent

tan m<H = JI/HJ

tan m<H = 48/55

tan m<H = 0.87 (to the nearest hundredth)

In ΔJKL, the measure of ∠L=90°, JL = 60, KJ = 61, and LK = 11. What ratio represents the tangent of ∠J?

Using SOH CAH TOA

tan theta = opposite/adjacent

LK is the opposite (facing m<J)

JL will be adjacent

tan m<J = LK/JL

tan m<H = 11/60

Hence the ratio that represents the tangent of ∠J is 11:60

Answer:

Point-slope form:

[tex]\displaystyle y-3=-\frac{1}{3}(x-3)[/tex]

Slope-intercept form:

[tex]\displaystyle y=-\frac{1}{3}x+4[/tex]

Step-by-step explanation:

We want the equation in point-slope form and slope-intercept form that passes through the points (-3, 5) and (3, 3).

First, we will find the slope between the two points. By the slope formula:

[tex]\displaystyle m=\frac{5-3}{-3-3}=\frac{2}{-6}=-\frac{1}{3}[/tex]

Point-slope form is given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

We can choose either point. I'm going to let (3, 3) be (x₁, y₁). The slope m is -1/3. Therefore:

[tex]\displaystyle y-3=-\frac{1}{3}(x-3)[/tex]

Is the point-slope form*.

To find the slope-intercept form, we simply need to isolate y. Distribute:

[tex]\displaystyle y-3=-\frac{1}{3}x+1[/tex]

Adding 3 to both sides yields:

[tex]\displaystyle y=-\frac{1}{3}x+4[/tex]

This is slope-intercept form.

*If you use the other point, the point-slope form will be:

[tex]\displaystyle y-5=-\frac{1}{3}(x+3)[/tex]

Answer:

[tex]Tiempo = \frac{1}{24}[/tex]

Step-by-step explanation:

La pregunta está incompleta, sin embargo, una posible pregunta podría ser calcular el tiempo que Carlos dedicará a estudiar cada asignaturas.

Para hacer esto, simplemente dividimos el tiempo disponible por el número de asignaturas.

Tenemos:

[tex]Tiempo\ disponible = \frac{1}{4}[/tex]

[tex]Numero\ de\ sujetos = 6[/tex]

Solución

[tex]Tiempo = \frac{Tiempo\ disponible}{Numero\ de\ asignaturas}[/tex]

[tex]Tiempo = \frac{1}{4} / 6[/tex]

[tex]Tiempo = \frac{1}{4} * \frac{1}{6}[/tex]

[tex]Tiempo = \frac{1}{24}[/tex]

Esto significa que dedicará 1/24 de su tiempo a cada

Answer:

x=0

Step-by-step explanation:

You must isolate the variable to solve for it, so subtracting 14 from the left is the first thing to do. This can be supported by using PEMDAS, whereas we are doing the inverse here to solve for something in the equation. This gives us 2x=0. Next, we have to divide by 2, which gives us x=0.

Answer:

acute

Step-by-step explanation:

Answer:

It is an acute triangle

Step-by-step explanation:

If it is an acute triangle, a^2 + b^2 > c^2

If it is a right triangle, a^2 + b^2 = c^2

If it is an obtuse triangle, a^2 + b^2 < c^2

If it is an equilateral triangle, a = b = c

6^2 +8^2  ?  9^2

36+64 ? 81

100 ? 81

? is >, meaning it is an acute triangle.

Answer:

P = 4(2x + 5)

P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

Step-by-step explanation:

Given that:

Perimeter of square = 4 * s

Where s = side length

If perimeter, P = 8x + 20

Then,

4s = 8x + 20

Divide both sides by 4

4s / 4 = (8x + 20) / 4

s = 2x + 5

P = 4s

P = 4(2x + 5)

Or

P = 2x + 5 in 4 places

P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

9/16

7 of the squares are 4 so we just substract that from the total of 16 and we get 9

Step-by-step explanation:

The Constitution gave the federal government the power to put down domestic rebellions, including slave insurrections. The framers of the Constitution believed that concessions on slavery were the price for the support of southern delegates for a strong central government.

Answer:

The North allowed the constitution to protect slavery because they belived that slavery was an unhuamne thing although all their production for industrialization did come from the south where the slaves worked on them.

Step-by-step explanation:

Answer:

4x+10y=-24

-2x+y=-24

2x+11y=-48

48+2x=0

48+11y =0

48=2x

48=11y

48/2 =2x/2

48/11=11y/11

x=24

y= 48/11

Answer:

-4ys + y - 88

Step-by-step explanation:

When we have to simplify equations that have different variables, we always have to look at the like terms, which the like terms are ones that contain the same value and variable. So let's look at our equation :

4y — 4ys + 2y – 5у — 54 – 34

We can see three different terms here :

ys, y, and a constant term.

The rule is that we can only combine two properties that have the same like term, so in the equation :

4y — 4ys + 2y – 5у — 54 – 34

These have the same variable, therefore we can combine like terms.

4y + 2y - 5y

6y - 5y

y

Now implace it into the equation :

y — 4ys — 54 – 34

Onto the next property :

y — 4ys — 54 – 34

This is alone, therefore we can leave it :

y — 4ys — 54 – 34

These two are the same property, so do the following :

-54 - 34

-88

Impace into the equation :

y - 4ys - 88

Now that we have no same common like terms, we can order our equation to greatest value to least :

-4ys + y - 88

The last option in the picture

Answer:

2 km/h

Step-by-step explanation:

Let x represent the speed of the river current, t₁ be the time spent rowing against the current and t₂ be the time spent rowing with the current.

Since the speed of the still water = 20 km/h.

The speed of rowing against the current = (20 - x)

The speed of rowing with the current = (20 + x)

We know that velocity = distance / time. Hence time = distance / velocity

t₁ = 36 / (20 - x)

t₂ = 22 / (20 + x)

but t₁ + t₂ = 3 hours

Therefore:

3 = 36 / (20 - x) + 22 / (20 + x)

multiply through by 400 - x²

3(400 - x²) = 36(20 + x) + 22(20 - x)

1200 - 3x² = 720 + 36x + 440 - 22x

3x² + 14x -40 = 0

This gives x = -6.7 or x = 2

x cannot be negative therefore x = 2 km/h

The speed of the river current is 2 km/h

Answer:

2km/h is correct
