Answer:

A square is a rhombus.

Step-by-step explanation:

A square is a geometrical figure which has four sides that are congruent. A rhombus is also a geometrical figure in which the four sides are congruent. Hence, it is true that a square is a rhombus. The difference between the two is that all the angles of a square are a right angle, while in rhombus the opposite angles are congruent.

7²+24²=49+576=625=25²≠26²

Answer:

11 or C

Step-by-step explanation:

We have to find the zeros, so we set h(t) as 0 and solve for t. Solving we get t=-3 or 11. Since the time cannot be negative, we have t=11.

Complete question:

Which object shown below could we slice perpendicular to its base/face to create a cross-section whose shape has two edges, one straight and one curved?

A- Cone

B- Cube

C- Cylinder

D- Sphere

Answer:

A- Cone

Step-by-step explanation:

A cone is a one of the geometric shapes in which objects exist in that we have. A cone is 3 Dimensional shape.

A cone has a top point and a base and it is formed when a group or send of lines are drawn from the top point and it's connects to the both sides of the base.

A cone is a shape that when we slice the perpendicular to its base/face, we create a cross-section and the resulting shape has two edges, one straight and one curved.

Answer:

$45-$2.50xx

Step-by-step explanation:

Let first of all determine the original amount on the gift card as follows

amount utilized=$2.50*16=$40

balance left after utilizing $40=$5

original amount on the gift card=amount utilized+balance left=$40+$5=$45

if xx cups of coffee is purchased ,the amount utilized would be xx*$2.50

i.e $2.50xx

The equation for the amount left would total amount on the gift card minus the $2.50xx

equation for amount remaining =$45-$2.50xx

If the questioner has duplicated x,which means he or she meant just x

equation of the amount remaining would=$45-$2.50x

Answer:

7183 cars

Step-by-step explanation:

On Friday, 2364 cars parked in the garage.

On Sunday, 2,455 more cars parked In the garage than on Friday.

This means that the number of cars parked on Sunday is 2455 plus the number of cars parked on Friday, that is:

2455 + 2364 = 4819 cars

Therefore, the number of cars parked in the garage in the two days is:

4819 + 2364 = 7183 cars

7183 cars were parked during the two days.

Answer:

a) 16[tex]\pi[/tex]

b) Using [tex]\pi[/tex] is more accurate because it represents the exact and full value of pi, rather than an estimation or approximation like 3.14.

Step-by-step explanation:

The formula to find the volume of a cone is [tex]\frac{1}{3} \pi r^{2} h[/tex]. We know the radius is 6, so all we need to find is the height, h. By using the Pythagorean theorem, we can see that the height is [tex]10^{2} - 6^{2} = \sqrt{64}[/tex], or 8. Plugging in all the values into the formula gives us:

V = [tex]\frac{1}{3} \pi (6)(8)[/tex]

V = 16[tex]\pi[/tex]

Answer:

-♾ < y < 5

Step-by-step explanation:

Range is set of all possible values for Y.

To know the range of value from graph one needs to see points on  axis beyond which the curve does not move.

Alternatively, we can say range is  the  value of y which is limiting the movement of curve beyond those limits.

Here we can see that upper point on curve is constrained at midpoint of  4 and 6 which is point 5.

Thus, upper limit is 5

which can be written as

y<5

___________________________________

For lower limit , it

Since , the at lower end curve is extended till the end of graph and the end of graph represents infinity. Also, this infinity is on the negative side of y .

Then lower end is -♾ .

which can be written as

y> -♾

Also we can see that graph is continuous one as there is no break in the curve between 5 and -♾.

Thus range of curve is from minus infinity to 5

which can be expressed as

-♾ < y < 5

Answer:

y = -3x + 2

Step-by-step explanation:

To find the slope of an equation you can do (y2-y1)/(x2-x1). Plug the values in from the equation and you get (-1+7)/(1-3), or 6/-2. This means the slope is -3. Then you plug the values of y and x into an equation y = -3x + b, and you get -1 = (-3)1 + b. Solve for b. -1 = -3 + b, (add 3 to each side) 2 = b. Then plug b back into your equation and you get y = -3x + 2

Answer:

-3x+2=y

Step-by-step explanation:

u need to find the slope intercept formula which mx+b=y

m=slope

b=y-intercept

first u should find the slope which is y2-y1/x2-x1

point 1:(1,-1)

point 2:(3,-7)

-7+1/3-1=-6/2=-3

m=-3

now replace the variables

-3(1)+b=-1

-3 times 1=-3

-3+b=-1

add 3 to both sides

b=2

now the equation is -3x+2=y

Answer:

Answer:

301

Step-by-step explanation:

Steps to solve:

5 − 2k = –2k

~Subtract 5 to both sides

5 - 5 - 2k = -2k - 5

~Simplify

-2k = -2k - 5

~Add 2k to both sides

-2k + 2k = -2k + 2k - 5

~Simplify

0 ≠ -5

Therefore, the equation as no solutions.

Answer:

31.8%

Step-by-step explanation:There are 7 months that have 31 days so,

The odds the first selected month has 31 days is 7/12

The next month there are only 6 months left with 31 days of only 11 months to choose from

so the odds for the second are 6/11

To calculate the odds they BOTH  have 31 months you multiply the two odds:

(7/12) x (6/11) = 42/132 = .318 so 31.8%

The required probability is 0.318 or 31.8% (in the form of a percentage) that 2 randomly selected months have 31 days.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

There are 7 months with 31 days, therefore

The probability that the first picked month has 31 days is 7/12.

There are just 6 months left with 31 days of only 11 months to choose from the following month.

As a result, the odds for the second are 6/11.

To determine the probabilities that they both have 31 months, multiply the two odds:

⇒ (7/12) × (6/11)

⇒  42/132

Apply the division operation,

⇒  0.318

⇒  31.8% in the form of a percentage

Thus, the required probability is 0.318 or 31.8% that 2 randomly selected months have 31 days.

Answer:

She used 600 square inches of paper.

Step-by-step explanation:

Since the box are 15 in x 10 in x 2 in and are stacked on top of each other, they form a bigger rectangular prism with 15 in x 10 in x 6 in. In order to calculate how much paper she used, we need to calculate the surface area of this prism, this is done by using the following formulla:

surface area = 2*width*length + 2*width*height + 2*length*height

surface area = 2*15*10 + 2*15*6 + 2*10*6 = 300 + 180 + 120

surface area = 600 in².

She used 600 square inches of paper.

The equation for the given phrase is 4x-7=37 and the solution for the obtained equation is 11.

The given unknown number is x.

Seven less than four times a number, x is

4x-7

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

So, the equation is

4x-7=37

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, the solution is

4x=37+7

4x=44

x=44/4

x=11

Therefore, the equation for the given phrase is 4x-7=37 and the solution for the obtained equation is 11.

Answer:

Infinite solutions

Step-by-step explanation:

Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:

2(n - 1) + 4n = 2(3n - 1)

2n - 2 + 4n = 6n - 2

Add like terms (2n and 4n):

6n - 2 = 6n - 2

Subtract 6n from both sides:

-2 = -2

Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.

Answer:

Cost of ordering t-shirts the same at both sides is 7

The cost is $85

Step-by-step explanation:

let x equal the number of tshirts

Hence:

15 + 10x = 50 + 5x

10x-5x= 50-15

5x = 35

35/5x

x = 7

Therefore the cost of ordering t-shirts the same at both sides is 7

The cost is $85
