Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that

x²>18

So, let take the square root of both sides

Then,

√x²>√18

x> ± 4.24

So it is either

x>4.24 or x<-4.24

Either of the two will gives a square higher than 18. You should note that the square of any number is always positive.

The applicable answer are

A. 5

Because

5²=25 which is greater than 18

D. 8

Because

8²= 64 which is greater than 18

F. -18

Because

(-18)²=-18×-18=324 which is greater than 18.

Step-by-step explanation:

its 20 and a half because 16+20=36 and you just need to add a half to 20 since your taking it away

Answer:

c=20.5 or 41/2

Step-by-step explanation:

c- 1/2 + 16=36

Make C the subject

c=36-16+1/2

c=20+1/2

Using LCM

c=(40+1)/2

c=41/2

c=20.5

To check if we are correct, we substitute c with 41/2. and then both sides of the equation must be equal

c- 1/2 + 16=36

41/2-1/2+16=36

To determine the length of ZY for it to be a tangent to circle X at point Y, we must know additional measurements, such as the radius of the circle, because a tangent is perpendicular to the radius at the point of tangency.

To determine the length of ZY so that it is tangent to circle X at point Y, we need to apply properties of tangents to a circle. A tangent to a circle forms a right angle with the radius at the point of tangency. Therefore, in a right-angled triangle, with the radius XY being one side and ZY being the hypotenuse, we could use the Pythagorean theorem if we know the length of the radius and any other segment connected to the radius or tangent.

Without further information, such as the length of radius XY or any other segment, it's not possible to calculate the exact length of ZY. However, the essential condition is that radius XY must be perpendicular to the tangent ZY at point Y for ZY to be a proper tangent.

The length of the rectangle is 11 units

The width of the rectangle is 5 units.

Explanation:

The equation of the trinomial is [tex]r^{2}-6 r-55[/tex]

We need to find the length and the width of the rectangle.

The length and width of the rectangle can be determined by factoring the trinomial [tex]r^{2}-6 r-55=0[/tex]

Factoring using the quadratic formula, we have,

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

where [tex]a=1, b=-6[/tex] and [tex]c=-55[/tex]

Substituting these in the above formula, we have,

[tex]r=\frac{-(-6) \pm \sqrt{(-6)^{2}-4 \cdot 1(-55)}}{2 \cdot 1}[/tex]

[tex]r=\frac{6\pm \sqrt{36+220}}{2}[/tex]

[tex]r=\frac{6\pm \sqrt{256}}{2}[/tex]

[tex]r=\frac{6\pm 16}{2}[/tex]

Hence, the two roots of the trinomial are

[tex]r=\frac{6+ 16}{2}[/tex] and [tex]r=\frac{6- 16}{2}[/tex]

Solving [tex]r=\frac{6+ 16}{2}[/tex] , we get,

[tex]r=\frac{22}{2}[/tex]

[tex]r=11[/tex]

Solving [tex]r=\frac{6- 16}{2}[/tex] , we get,

[tex]r=\frac{-10}{2}[/tex]

[tex]r=-5[/tex]

Thus, the solutions of the trinomial are 11 and -5

Since, the length of the rectangle is larger than the width, the length of the rectangle is 11 units.

Also, the width of the rectangle cannot be negative.

Thus, ignoring the negative sign, we have, [tex]r=5[/tex]

Hence, the width of the rectangle is 5 units.

Answer: 30 min.

Step-by-step explanation: for this, you have to find the gcf of 5 and 6, which is 30.

Final answer:

Mike and Sam will both cross the starting line together after 30 minutes of running, as 30 minutes is the least common multiple of their individual lap times of 5 and 6 minutes.

Explanation:

To find out how long it will take for Mike and Sam to cross the starting line together again, we need to determine the least common multiple (LCM) of their lap times. Mike runs a lap in 5 minutes and Sam runs a lap in 6 minutes. The LCM of 5 and 6 will give us the first time they both cross the starting line at the same time after they start running.

To calculate the LCM of 5 and 6, we list the multiples of each number until we find a common one:

5, 10, 15, 20, 25, 30, ...

6, 12, 18, 24, 30, ...

The smallest common multiple of 5 and 6 is 30. Therefore, Mike and Sam will both cross the starting line together after 30 minutes of running.

The cost of one hot dog is $1.75

The cost of one hamburger is $1.5

Step-by-step explanation:

Let,

The equations can be formed as :

7x + 4y = 18.25  --------(1)

4x + 7y = 17.50  --------(2)

Multiply eq (1) by 4 and eq (2) by 7,

   28x + 16y = 73

- (28x + 49y = 122.5)

         - 33y = - 49.5

y = 49.5/33

y = 1.5

The cost of one hamburger is $1.5

Substitute y=1.5 in eq (1),

7x + 4(1.5) = 18.25

7x = 18.25 - 6

x = 12.25/7

x = 1.75

The cost of one hot dog is $1.75

Answer:

A system of equations that allows you to solve for how many bags of each candy Oscar bought is [tex]16x+8(x+5)=400[/tex] and The number of bags of lemon drops and number of bags of beans are 15 and 20 respectively

Step-by-step explanation:

Let x be the number of bags of lemon drops

We are given that The number of bags of beans was 5 more than the number of bags of lemon drops

So, The number of bags of beans =x+5

Jelly bean bags weigh 8 ounces, and drop bags weigh 16 ounces each.

So, Weight of x bags of lemon drops = 16x

So, Weight of (x+5) bags of lemon drops = 8(x+5)

The total weight of all the bags of candy was 400 ounces.

So, [tex]16x+8(x+5)=400[/tex]

[tex]16x+8x+40=400[/tex]

[tex]24x+40=400[/tex]

[tex]24x=360[/tex]

[tex]x=\frac{360}{24}[/tex]

x= 15

The number of bags of lemon drops are 15

The number of bags of beans =x+5 =15+5=20

Hence a system of equations that allows you to solve for how many bags of each candy Oscar bought is [tex]16x+8(x+5)=400[/tex] and The number of bags of lemon drops and number of bags of beans are 15 and 20 respectively

Answer:

It would be A:likely

Step-by-step explanation:

let's take rounding decimals for example; when you 5.86 and you were rounding to the nearest tenth it would be 5.9. That is because the 6 is greater than 5, so for the weather the highest the percentage it can be is 100% and 50% is half and since it is more than half then it would be more likely.

Final answer:

To find the value of x, set the two expressions for the lengths of the sides of the rectangle equal to each other and solve. The value of x is 2. To find the length of each diagonal, use the Pythagorean Theorem with the lengths of the sides of the rectangle. The length of each diagonal is 13 * sqrt(2).

Explanation:

To find the value of x, we can set the two expressions for the lengths of the sides of the rectangle equal to each other, since opposite sides of a rectangle are congruent. So, we have:

6x + 1 = 9x - 5

To solve for x, we can subtract 9x from both sides and add 5 to both sides:

1 + 5 = 9x - 6x

6 = 3x

x = 2

Therefore, the value of x is 2. To find the length of each diagonal, we can use the Pythagorean Theorem. The diagonal of a rectangle acts as the hypotenuse of a right triangle formed by the sides of the rectangle. In this case, the length of one side is 6x + 1, and the length of the other side is 9x - 5. So, the length of each diagonal is:

d = sqrt((6x + 1)^2 + (9x - 5)^2)

d = sqrt((6(2) + 1)^2 + (9(2) - 5)^2)

d = sqrt(13^2 + 13^2)

d = sqrt(2 * 13^2)

d = 13 * sqrt(2)

Answer:

10 bows

Step-by-step explanation:

Each bow is 0.5 yards and you have 5 yards of ribbon. In equation form (where x = number of bows), that looks like: 0.5 * x = 5. Solve for x and you'll get x = 10.

This mathematics problem can be solved by multiplication. Since each bow requires half a yard of ribbon, each yard can produce two bows. Therefore, five yards of ribbon can produce 10 bows.

The question requires us to determine how many bows we can make with a given number of yards of ribbon. Since it takes half a yard of ribbon to make a bow, you can fit two bows in a single yard. To find how many bows can be made with 5 yards, you can perform multiplication.

To do this, you would multiply the number of yards by 2, since each yard can create two bows: 5 yards × 2 = 10 bows. So, you can make 10 bows out of 5 yards of ribbon.

Answer:

Here the degree of the polynomial is 11.

Step-by-step explanation:

To find the degree of the multivariate polynomials, we need to add up the powers of all the variables.   So the total degree is given by the sum of all the powers of the highest powers terms.

Now in the given polynomial [tex]-3w+x^6y^5-2+5y^4w^3x^2[/tex]

the term with the highest total powers is [tex]x^6y^5[/tex] and thus the total power is 6+5=11.

And hence the degree of this polynomial is 11.

Answer:

D(4) = -18

Step-by-step explanation:

D(n) = D(n – 1)(-6)

D(1) = 1/12

D(2) = D(2 – 1)(-6)

D(2) = D(1)(-6)

D(2) = 1/12 * (-6)

D(2) = -6/12

D(2) = -1/2

D(3) = D(3 – 1)(-6)

D(3) = D(2)(-6)

D(3) = -1/2 * (-6)

D(3) = 6/2

D(3) = 3

D(4) = D(4 – 1)(-6)

D(4) = D(3)(-6)

D(4) = 3 * (-6)

D(4) = -18

Answer:

D(4) = -18

Step-by-step explanation:

the surface area of the equilateral triangular pyramid is approximately 21.03 square inches.

Let's calculate the surface area of the pyramid.

The lateral area of the pyramid, which is the sum of the areas of the three triangular faces, can be calculated using the formula:

[tex]\[ LA = \frac{1}{2} \times \text{perimeter of the base} \times \text{slant height} \][/tex]

We've already determined the perimeter of the base is 4.8 inches and the slant height is 8.3  inches. Substituting these values:

[tex]\[ LA = \frac{1}{2} \times 4.8 \times 8.3 = 19.92 \text{ square inches} \][/tex]

However, this only gives us the lateral area. To find the total surface area, we need to add the area of the base. Since it's an equilateral triangle, we can use the area formula for equilateral triangles:

[tex]\[ A_{\text{base}} = \frac{\sqrt{3}}{4} \times (\text{side length})^2 \][/tex]

The side length is [tex]\( \frac{4.8}{3} = 1.6 \)[/tex] inches, so:

[tex]\[ A_{\text{base}} = \frac{\sqrt{3}}{4} \times (1.6)^2 = \frac{\sqrt{3}}{4} \times 2.56 \approx 1.1084 \text{ square inches} \][/tex]

The total surface area is then the sum of the lateral area and the area of the base:

[tex]\[ SA = LA + A_{\text{base}} = 19.92 + 1.1084 = 21.0284 \text{ square inches} \][/tex]

Thus, the surface area of the equilateral triangular pyramid is approximately 21.03 square inches.

The question probable maybe:

An equilateral triangular pyramid has a slant height of 8.3 inches. The triangular base has a perimeter of 4.8 inches and an area of 1.1084 square inches. Find the surface area of the pyramid.
