Step-by-step explanation:

Answer:

21 cups of sugar

Step-by-step explanation:

so it gives you the ratio for cups of sugar(or as i'm going to use it, COS) and cups of flower(COF), which is 3:2, so if you have 14 cups of flower, you would divide 14 by the COF part of the ratio, which is 2, which gives you 7, then you would multiply the COS part of the ratio, which is 3, by 7 to get the number of cups of sugar needed for 14 cups of flower.

Answer:

1,187 (It is the closest)

Step-by-step explanation:

Formula: 2πrh+2πrr

Equation: 2x3.147x20 + 2x3.14x7x7

Solution:879.2 + 307.72=1,186.92

The surface area of the cylinder with a radius of 7 inches and a height of 20 inches is closest to 1,187 square inches.

A cylinder is a three dimensional geometric figure on which there are two identical circular bases which are parallel to each other located within a distance. This distance is called the height of the cylinder and the radius is the radius of this circle.

Axis of cylinder is the line segment connecting the center of two circular bases.

Here, we have to find the surface area of the cylinder.

Height of the cylinder = 20 inches

Radius of the cylinder = 7 inches

Surface Area of the cylinder = 2πr (h + r), where h is the height of the cylinder and r is the radius of the cylinder.

Surface Area = 2π × 7 (20 + 7)

                      = 2π × 7 × 27

                      = 2π × 189

                      = 378π

                      = 378 × 3.14

                      = 1186.92 ≈ 1187

Hence the surface area of this cylinder is closest to 1187 square inches.

Answer:

The actual width of the hair is 20 / 150 = 0.13 mm

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.

The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.

The hair can be seen 2 cm wide in the photograph.

Converting to millimeters, 2 cm = 2*10 = 20 millimeters.

The actual width of the hair is 20 / 150 = 0.13 mm

Answer:

c

Step-by-step explanation:

The solution to the equation is x = -1 and x =7, the correct option is C.

An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.

The equation is

x - (7/x) = 6

On solving the equation,

(x² -7) = 6x

x² - 7 = 6x

x² -6x -7 =

x² - 7x +x -7 = 0

x( x-7) +1(x-7)= 0

(x+1)(x-7) = 0

x = -1,7

Answer:

  G  (-2, -3) is in the solution set

Step-by-step explanation:

Finding the solution set

You are given the boundary lines for the inequalities, but the graph does not show the solution set.

The line for inequality y < -2x -4 is the one with negative slope that extends from upper left to lower right. The relation of y to the comparison symbol is ...

  y <

indicating that y-values in the solution set will be less than those on the line. The line itself is NOT included in the solution set. That is, "shading" will be below and left of the line.

__

The line for inequality 2x - 4y ≤ 8 is the one with positive slope. Considering the variable with the positive coefficient, its relation to the comparison symbol is ...

  x ≤

indicating that x-values in the solution set will be less than (or equal to) those on the line. The line IS included in the solution set. Shading will be above and left of the line with positive slope.

Then the doubly-shaded area is the quadrant at the left side of the X where the lines cross. The lower boundary of that is included in the set, while the upper boundary is not.

__

Considering the points

Now that you know the location of the solution set, you can decide whether any given point is in it, or not.

Plotting the points, you find that F and G are on the boundary lines, and H and J are outside the solution set. Point F(-2, 0) is on the upper boundary line, so is not in the solution set, either.

The point listed in choice G, (-2, -3) is in the solution sets of both inequalities.

Answer:

Step-by-step explanation:

Given cotA = 40/9

1/tanA = 40/9

tanA = 9/40

According to SOH, CAH, TOA

tan A = 9/40 = opposite/adjacent

Get the hypotenuse

hyp² = opp²+adj²

hyp² = 9²+40²

hyp² = 81+1600

hyp² = 1681

hyp = √1681

hyp = 41

Het sec A

sec A = 1/cosA

Since cos A = adjacent/hypotenuse

cos A = 40/41

secA = 1/(40/41)

SecA = 41/40

Hence the exact value of secA is 41/40

Answer: 55.4 mins

Step-by-step explanation:

pragnesh and qazi = 2hrs

pragnesh and roghui = 3hrs

qazi and roghui = 4hrs

this means for every 1 hour they wold paint.

pragnesh and qazi = [tex]\frac{1}{2}[/tex] half of the fence

pragnesh and roghui = [tex]\frac{1}{3}[/tex]

qazi and roghui = [tex]\frac{1}{4}[/tex] quarter of the fence

time taken when they all work together

= [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{4}[/tex]

= [tex]\frac{13}{12}[/tex]

= [tex]\frac{12}{13}[/tex]

= 0.9231 × 60(mins)

= 55.4 mins

Step-by-step explanation:

96 divided by 8 = 12

12 times 8 = 96

BRAINLIEST PLEASE

The number of containers, c, that Henry needs to pack all the marbles will be B. 96 = 8 x c.

Since Henry has 96 marbles and is packing containers with 8 marbles in each container, the equation to solve the number of containers needed will be;

96 = 8 x c.

96 = 8c

c = 96/8

c = 12

Therefore, 12 containers will be needed.

Answer: B=1, C=2 and A =0.

Step-by-step explanation:

On a coordinate plane ,  a horizontal line is parallel to x-axis with 0 slope(m) .

Every horizontal line is written as y=c   [∵ y= mx+c , here m=0 ]

Here value for x changes but values for y is fixed as c.

If the horizontal line passes through (-4,2), so for some point x= -4 and y=2.

So, Equation of line must be y=2, which can be written as (0)x+(1)y =2

By comparing this to Ax + By = C, we get B=1, C=2 and A =0

Answer:

in slope intercept form it would be y = -x + 4

Step-by-step explanation:

your equation: 2x +2y =8

subtract 2x from both sides: 2y = -2x + 8

divide both sides by 2: y = -x + 4
