There's a stack of 3 presents that is 9/8 feet tall. How tall is each present?

Answer:

False

Step-by-step explanation:

The first part of the statement is correct with it saying to have an open circle on -3, but the shading should go on the right because x is bigger than -3. When you picture a number line, the numbers on the right of -3 are bigger than the numbers on the left.

The statement " To graph the inequality x > -3, draw an open circle on -3 and shade to the left" is wrong.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

The first part of the statement is correct, as it states that an open circle should be placed on -3, but the shading should be placed on the right because x is greater than -3. On a number line, the numbers to the right of -3 are larger than the numbers to the left.

Step-by-step explanation:

Answer:

Answer:

The length of the base is 11 meters.

Step-by-step explanation:

The diagram of the triangle is not shown; However, the given details are enough to solve this question.

Given

Shape: Triangle

Represent the height with h and the base with b

\(b = 3 + 2h\)

\(Area = 22\)

Required

Find the length of the base

The area of a triangle is calculated as thus;

\(Area = \frac{1}{2} * b * h\)

Substitute 22 for Area and 3 + 2h for b

The formula becomes

\(22 = \frac{1}{2} * (3 + 2h) * h\)

Multiply both sides by 2

\(2 * 22 = 2 * \frac{1}{2} * (3 + 2h) * h\)

\(44 = (3 + 2h) * h\)

Open the bracket

\(44 = 3 * h + 2h * h\)

\(44 = 3h + 2h^2\)

Subtract 44 from both sides

\(44 - 44 = 3h + 2h^2 - 44\)

\(0 = 3h + 2h^2 - 44\)

Rearrange

\(0 = 2h^2 +3h - 44\)

\(2h^2 +3h - 44 = 0\)

At this point, we have a quadratic equation; which is solved as follows:

\(2h^2 +3h - 44 = 0\)

\(2h^2 + 11h - 8h - 44 = 0\)

\(h(2h + 11) - 4(2h + 11) = 0\)

\((h - 4)(2h + 11) = 0\)

Split the above

\((h - 4) = 0\ or\ (2h + 11) = 0\)

\(h - 4 = 0\ or\ 2h + 11 = 0\)

Solve the above linear equations separately

\(h - 4 = 0\)

Add 4 to both sides

\(h - 4 + 4 = 0 + 4\)

\(h = 0 + 4\)

\(h = 4\) ---- First value of h

\(2h + 11 = 0\)

Subtract 11 from both sides

\(2h + 11 - 11 = 0 - 11\)

\(2h = 0 - 11\)

\(2h = -11\)

Divide both sides by 2

\(\frac{2h}{2} = -\frac{11}{2}\)

\(h = -\frac{11}{2}\) ------ Second value of h

Since height can be negative, we'll discard \(h = -\frac{11}{2}\)

Hence, the usable value of height is \(h = 4\)

Recall that \(b = 3 + 2h\)

Substitute 4 for h

\(b = 3 + 2(4)\)

\(b = 3 + 8\)

\(b = 11\)

Hence, the length of the base is 11 meters

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

C. -6.1, -6 4/9, 6.3..., 630%

Step-by-step explanation:

-6.1 in mixed number form is -6 1/10, making it greater than -6 4/9. This is because, if the numbers were positive, -6 4/9 would be greater than -6.1, but since the numbers are negative, it's opposite.

Answer: In the first 2 hours, Doug drove 2 * 50 = <<250=100>>100 miles on the state road.

In the next 3 hours, he drove 3 * 60 = <<360=180>>180 miles on the interstate highway.

Therefore, he drove a total of 100 + 180 = <<100+180=280>>280 miles.

Since we don't know his distance from home before he began driving, we cannot calculate his distance from home after 5 hours of driving.

Answer:

The line x=b2a will serve as the parabola's axis of symmetry.

Detailed explanation:

Graph the parabola y=x2−7x+2 .

To get the values of a, b, and c, compare the equation with y=ax2+bx+c.

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

To write the axis of the symmetry equation, use the coefficient values.

The line x=b2a serves as the axis of symmetry for a quadratic equation of the form y=ax2+bx+c. Therefore, x=(7)2(1) or x=72 is the equation of the axis of symmetry of the given parabola.

To determine the vertex's y coordinate, change x=72 in the equation.

y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84  =−414

The vertex's coordinates are (72, 414) as a result.

Data: (Cylinder)

h (height) = 8 cm

r (radius) = 5 cm

Adopting:

V (volume) = ?

Solving:(Cylinder volume)

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 5 cm

Adopting:

If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (Volume of the hemisphere)

Solving:

Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)

Answer:

Step-by-step explanation:

The amounts greater than 40 cents can be formed.

After dividing one number by another, the modulo operation yields the remainder or signed remainder of the division.

Given:

According to the situation the equation can be

C = 5x + 11y, where x and y are non negative integers.

Now, We will fix y-values first, because there are fewer indices modulo 5:

y = 0 --> 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55,... 5y

y = 1 --> 11, 16, 21, 26, 31, 36, 41, 46, 51, 56,... 5y + 11

y = 2 --> 22, 27, 32, 37, 42, 47, 52, 57, ...5y + 22

y = 3 --> 33, 38, 43, 48, 53, 58, ...5y + 33

y = 4 --> 44, 49, 54, 59, ...5y + 44

Then, 39 may be verified to be the smallest number that is impossible to obtain.

By examining each index (0, 1,..., 4), we may demonstrate this by observing that for y = 1, 6 is the largest positive integer congruent to 1 mod 5 that cannot be made, 17 is the largest positive number congruent to 2 mod 5, etc.

The largest of these improbable numbers is 39.

We could say that since 40, 41, ..., 44 are all obtainable, then we can induct by adding a multiple of 5 (i.e. if k is possible, so is k+5),

Hence, all amounts greater than 40 cents can be formed.

a ) x + 3 = 11, x = 8

b) 3x = 9, x = 3

c) x - 7 = 7, x = 7

d) 3x = 3, x = 1

Step-by-step explanation:

a) There is one green rectangle and 3 yellow triangles on one side and 11 yellow squares on the other side. They're on that thing where in order to balance each side has to be equal, so one green rectangle + 3 yellow squares = 11 yellow squares.

the green thing is x, the yellow thing is 1.

add them up, which makes the equation x + 3 = 11

subtract 3 from both sides

x = 8

You do the same process with each equation.
