I NEED HELP!! Q: Mary bought 12 pounds of blueberries to make 5 pies. She divided the blueberries evenly. How many pounds of blueberries were in each pie?

A:???

Answer:

the number is 40

Step-by-step explanation:

A number decreased by 20 is 10 less than twice the number

Distance: 19

Steps:

Distance (d) = √(16 - -3)2 + (8 - 8)2

= √(19)2 + (0)2

= √361

=          19

The  time that the rocket will hit the ground to the nearest tenth of a foot is 17 secs.

We were given the equation as y=-16x^2+261x+130 , thene we can equate this to zero. as

0=-16x^2+261x+130

from this we can see that this is a quadratic equation, where a= -16, b=261, c =130

Then input into the quadratic formular we have:

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

Then if we input the values we have [tex]x=\frac{-261+-\sqrt{261^{2}-4*-16*130} }{2*-16}[/tex]

Then the value of x are: -0.49 and 16.79

The positive value is the time that the rocket will hit the ground. Therefore, the rocket will hit the ground after 16.79 secs.

Step-by-step explanation:

On using the scale value of 2 : 1, the area of green parallelogram is obtained as 120 in².

What is a parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side.

Height of blue parallelogram = 6 inches

Base of blue parallelogram = 10 inches

The scale value is given as = 2 : 1

Height of green parallelogram = 6 × 2 = 12 inches

Base of green parallelogram = 10 × 1 = 10 inches

It is known that area of parallelogram = base × height

So, area of green parallelogram is -

= 12 × 10

= 120 in²

Therefore, the area value is obtained as 120 in².

Answer:

Area: T = 24

Perimeter: p = 24

Semiperimeter: s = 12

Step-by-step explanation:

We know the lengths of all three sides of the triangle, so the triangle is uniquely specified.

a=6

b=8

c=10

The triangle perimeter is the sum of the lengths of its three sides

p=a+b+c=6+8+10=24

The semiperimeter of the triangle is half its perimeter. The semiperimeter frequently appears in formulas for triangles to be given a separate name. By the triangle inequality, the longest side length of a triangle is less than the semiperimeter.

Heron's formula gives the area of a triangle when the length of all three sides is known. There is no need to calculate angles or other distances in the triangle first. Heron's formula works equally well in all cases and types of triangles.

(-4, 10), (-4, 4), (4, 10), (4, 4).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, A quadrilateral with vertices  (-2,5), (-2,2), (2,5), (2,2).

Now, Dialating this quadrilateral with a scale factor of 2 centered at the origin would multiply every vertices points by 2.

What is the co-plaer and non co-planer?

Co-planar refers to a set of objects that lie in the same plane or lie on the same flat surface. They have the same elevation and do not intersect each other.

Non-coplanar refers to a set of objects that are not in the same plane or do not lie on the same flat surface. They have different elevations and may intersect each other.

W is a point that is not co-planar with R, S, and T.

Consider the provided plane.

We need to find the point that is not co-planar with R, S, and T.

Co-planar: Two object or points are said to be co-planer if they lie in the same plane.

Non co-planar: Two object or points are said to be non co-planer if they don't lie in same plane.

Now consider the provided plane, the point W is not lie in the plane V.

Angel should increase the dimensions of the deck by 5 feet each

From the question, we have the following parameters that can be used in our computation:

Length = 20 feet

Width = 25 feet

So, the area is

Area = 20 * 25

Evaluate

Area = 500

When increased by 50%, we have

(20 + x) *(25 + x) = 500 * 1.50

Evaluate

(20 + x) * (25 + x) = 750

Express 750 as 25 * 30

So, we have

(20 + x) * (25 + x) = 25 * 30

This means that

20 + x = 25

25 + x = 30

The  Distance between B to C = 58 km,

distance between C to D = 30 km

Average speed between B to C = 59.79 km/h

The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.

Given  A commuter train moves from station A to D via B and C,

distance from A to C via B = 70 km

distance from B to D via C = 88 km

av. speed of the train from A to B = 48 km/h

av. speed of the train from C to D = 45 km/h

time taken by train to reach B = 15 min = 15/60  = 0.25 hour

distance between A to B = speed x time from A to B

distance between A to B = 48 x 0.25

distance between A to B = 12 km

A. Distance between B to C = distance from A to C - distance between A to B

Distance between B to C = 70 - 12 = 58 km

B. distance between C to D = distance from B to D -  Distance between B to C  

distance between C to D = 88 - 58 = 30 km

C. let av. speed from B to C is x

total distance covered by train  = 12 + 58 + 30 = 100 km

av. speed for journey = 50 km/h

time taken to complete journey = 100/50 = 2 hours

time is taken from A to  B = 0.25 hour

time is taken from B to C = 58/x

Time is taken from C to D = 30/45 = 0.66 hour

halt at b = 3 minute and halt at C = 4 minute

total halt = 3 + 4 = 7 minute = 7/60 = 0.12 hour

Total time  = time taken from(A to B + B to C + C to D) + total hault

2 = 0.25 + 58/x + 0.66 + 0.12

58/x = 0.97

The area and the perimeter of the figure are given as follows:

The figure is composed as follows:

Applying the Pythagorean Theorem, the diameter of the circle is given as follows:

d² = 2 x 12²

[tex]d = \sqrt{2 \times 12^2}[/tex]

d = 16.97 cm.

Then the radius of the circle is given as follows:

r = 0.5d

r = 0.5 x 16.97

r = 8.485 cm.

The area of a circle of radius r is given by the multiplication of π and the square of the radius, as follows:

A = πr².

Hence, considering that the figure is a semi circle, we have that:

Ac = 0.5 x π x (8.485)²

Ac = 36π

The area of the right triangle is of:

At = 0.5 x 12 x 12

At = 72 cm².

Meaning that the area of the shape is given as follows:

A = Ac + At.

A = 36π + 72

A = 36(π + 2) cm².

The perimeter of the shape is obtained by the sum of 2 times 12 cm and the circumference of the semi circle.

The circumference of a semicircle of diameter d is given as follows:

C = 0.5πd.

Hence:

C = 0.5π x 8.485

The point estimate of the population mean is 21.

The point estimate of the population mean is the midpoint of the confidence interval.

To find the midpoint, add the lower and upper bounds of the interval and divide by 2. In this case, the lower bound is 17 and the upper bound is 25, so the point estimate of the population mean is (17 + 25) / 2 = 21.

On the other hand, the margin of error is a measure of the precision of the estimate. It is the amount by which the estimate could be off and still be considered accurate. The margin of error is typically expressed as a percentage of the point estimate. In this case, the margin of error would depend on the level of confidence you have in the estimate and the size of the sample you used to generate the interval.
