Write 63/90 and 30/42 as fraction In simplest form then determine whether the ratio form a proportion

Answer:

  (a)  11

Step-by-step explanation:

You want the degree of the monomial 7m^6n^5.

The degree of a monomial is the sum of the exponents of its variables.

  m has an exponent of 6

  n has an exponent of 5

The degree is 6+5 = 11.

Therefore , the solution of the given question of triangle  comes out to be the only true option is A.

Triangles, which have three sides and three angles, can be made by joining any three points in a plane. One of the first geometric shapes to be examined was them. They are especially crucial because any polygon, regardless of its number of sides (four, five, six, or n), may be divided into a triangle.

Answer:

Below.

Step-by-step explanation:

The line of length 48 = 1/2 of the baseline (3x) as the line 48 joins the midpoints of the 2 sloping sides.

1/2 * 3x = 48

multiply both sides by 2:

3x = 96

x = 32.

Here is the complete question

Caylan is making baked goods for a charity bake sale. He places a tray of scones, a tray of muffins, and a tray of cookies in the oven. The scones bake for 15 minutes, the muffins bake for 12 minutes, and the cookies bake for 10 minutes. When one tray is done, he removes it and replaces it with another tray of the same item. How many minutes after Caylan puts the trays in the oven will he first remove the scones, muffins, and cookies at the same time? ? minutes​

The multiples for scones = 15 = 3,5

The multiples for muffins = 12 =2, 2,2,3

The multiples for cookies = 2, 5

Lowest common multiple = 2 x 2 x 3 x 5 = 60 minutes

to determine the time , calculate the lowest common multiple of 12, 15 and 10

Answer:

60 - This is due to the times of each and what time you would take them out.

The line x= -4 is a vertical line passing through x-axis.

It is a distance of 4 units from the x-axis and is parallel to the y-axis.

Vertical Line in a coordinate plane refers to a line that is perpendicular to the Y-axis. From top to bottom and from bottom to top, it is a straight line. The x-coordinate of every point along this line will be the same. The points of vertical lines include, for instance, (2,0), (3,0), (-4,0), etc. Similar to this, a horizontal line is a line that runs parallel to the x-axis from left to right.

There is no slope to the vertical lines. It follows the y-axis parallel, hence the slope is not known. As a result, the equation for the vertical line that at any point, let's say 'a', crosses the x-axis is:

x = a

where x is a point on the line's coordinate.

Step-by-step explanation:

triangles equal to 180, 56+73+51 equals 180 :)

brainliest pls

Answer:

m∠C  = 51°

Step-by-step explanation:

By definition of interior angles of a triangle, the ∑ΔABC's interior angles = 180°.

It is given that m∠A = 56° & m∠B = 73°. Set the equation:

56 + 73 + m∠C = 180

First, combine like terms:

(56 + 73) + m∠C = 180

m∠C + 129 = 180

Next, isolate the term, m∠C. Note the equal sign, what you do to one side, you do to the other. Subtract 129 from both sides:

m∠C + 129 (-129) = 180 (-129)

m∠C = 180 - 129

m∠C  = 51°

51° is your answer for m∠C.

Answer:

the graph's slope-intercept is 3 or 3/1. you do this by finding the rise over run (how many squares does it go up, and how many does it go over).

The Y-intercept is -2. You can always find this by using the formula y= mx + b. Whatever number is in the place of "b" is the y-intercept.

I'm going to take a guess and say you're in Algebra 1. Either that or Pre-Algebra. This stuff took me a little while to full grasp, so don't worry! YOu'll understand it soon enough!

Answer:

Slope of perpendicular line: 5

Slope of parallel line: -1/5

Step-by-step explanation:

Convert the equation to slope-intercept form (y=mx+b where m is the slope and b is the y-intercept)

x+5y=6

subtract x on both sides

5y=-x+6

divide by 5 on both sides

y=-(1/5)x+6/5

The slope of this equation is the coefficient of x, -1/5.

The slopes of two perpendicular lines are negative reciprocals of each other.

To get the negative reciprocal of a number, flip the numerator and denominator and multiply by -1.

-1/5 becomes 5, so that's the slope of a line perpendicular to our original line.

Parallel lines have the same slope, so that's just -1/5.

Slope of perpendicular line: 5

Slope of parallel line: -1/5

Answer:

C

Step-by-step explanation:

We want to solve the equation:

[tex]x^2+2x+7=0[/tex]

Using the quadratic formula. The quadratic formula is given by:

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In this case, a = 1, b = 2, and c = 7.

Substitute:

[tex]\displaystyle x=\frac{-(2)\pm\sqrt{(2)^2-4(1)(7)}}{2(1)}[/tex]

Evaluate:

[tex]\displaystyle x=\frac{-2\pm\sqrt{-24}}{2}[/tex]

Simplify the square root:

[tex]\sqrt{-24}=\sqrt{4\cdot 6\cdot -1}=\sqrt{4}\cdot\sqrt{6}\cdot\sqrt{-1}=2i\sqrt{6}[/tex]

Hence:

[tex]\displaystyle x=\frac{-2\pm2i\sqrt{6}}{2}[/tex]

Simplify:

[tex]\displaystyle x=-1\pm i\sqrt{6}[/tex]

Hence, our solutions are:

[tex]\displaystyle x=\left\{-1+i\sqrt{6}, -1-i\sqrt{6}\right\}[/tex]

Our answer is C.

Choose the variable whose numerical coefficients are smaller or have a smaller common multiple.

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:

1000 hours

Step-by-step explanation:

∫xf(x)dx = ∫x*xdx (1,0) + ∫x*(8-x)dx (2,1)

∫xf(x)dx = ∫x²dx (1,0) + ∫8x - x²dx (2,1)

∫xf(x)dx = ∫x²dx (1,0) + ∫8xdx (2,1) - ∫x²dx (2,1)

∫xf(x)dx = x³/3(1,0) + 8x²/2 (2,1) - x³/3(2,1)

∫xf(x)dx = 1/3 + 8(4/2 - 1/2) - (8/3 - 1/3)

∫xf(x)dx = 1/3 + 8(2-0.5) - (7/3)

∫xf(x)dx = 1/3 + 8(1.5) - 7/3

∫xf(x)dx = 1/3 + 12 - 7/3

∫xf(x)dx = - 6/3 + 12

∫xf(x)dx = - 2 + 12

∫xf(x)dx = 10

The scale factor of the dilation is 2. An expansion happens when the scaling factor's absolute value exceeds one.

The scale factor is defined as the proportion of the new image's size to that of the previous image. A fixed location in the plane serves as the center of dilatation. The scale factor and the center of dilation are used to determine the dilation transformation. The image stretches if the scaling factor is greater than 1.

Answer:

900 meters

Step-by-step explanation:

If the height of the building (unknown) is opposite of the angle of elevation (20°) and the distance from the building (402 meters) is adjacent to the angle of elevation, then we use the tangent function to find the height of the building:

tanθ=opposite/adjacent

tan(20°)=x/402

402tan(20°)=x

900=x

Therefore, the height of the skyscraper is 900 meters.

Answer:

24

Step-by-step explanation:

Number of sides = 15 (counted and it was a pain the a*s)

The total measure of the exterior angle = 360

= 360/15

= 24 degree

Each angle is measured 24 degree

The sum of the exterior angles of the polygon shown in the image is: 360°.

Regardless of the number of sides or angles a polygon has, the sum of exterior angles of any polygon is always 360 degrees.

Thus, the polygon given has 15 sides, however, the sum of all its exterior angles will still give 360 degrees.

Therefore, the sum of the exterior angles of the polygon shown in the image is: 360°.
