Answer:

The answer is 48 degrees

Step-by-step explanation:

If you look at both symbols, JKL and PQR they are supposed to be exactly the same. Another way is Taking J=52 and R=80 and add them together. Then you subtract them by 180 because thats the area of all triangles. Hope this helps! <3

Answer:

lost thermal energy and mass to the surroundings

Answer:

B = 82

Step-by-step explanation:

180 = 143 - A

-143     -143

37 = A

That is to find the measure of angle A

180 = 61 + 37 + B

180 = 98 + B

-98      -98

82 = B

Answer:

D. 200

Step-by-step explanation:

If you would like to solve 32% of a number is 64, you can calculate this using the following steps:

32% of a number is 64

32% * x = 64

32/100 * x = 64     /*100/32

x = 64 * 100 / 32

x = 200

Result: 32% of 200 is 64.

Answer:20

Step-by-step explanation:

Answer:

20 students

Step-by-step explanation:

20 students

We know that 5% of 100 is 5

And 5% of 200 is 10

5% of 300 is 15

So that must mean 5% of 400 is 20

Hopefully this solves your problem! Hope you have a good day!

Answer:

m= -1/2

y= -1/2x+1+3

y= -1/2 x +4

Step-by-step explanation:

Hey there

Given;

[tex](y - 3 )= \frac{ - 1}{2} (x - 2)[/tex]

Comparing the equation with (y-y1) = m(x-x1). We get,

[tex]slope(m) = \frac{ - 1}{2} [/tex]

Hope it helps...

Answer:

y=1/2x

Step-by-step explanation:

Slope intercept form is the most commonly used linear equation:

It goes like this:

[tex]y=mx+b[/tex]

In this equation, m is the slope and b is the y-intercept.

Your line has a slope of 1/2. So, your m-value is 1/2.

y=1/2x+b

B, your y-intercept, is at the origin.

The origin is the point (0,0).

So b, is 0 (y-intercept is the y-value when x is 0)

y=1/2x+0

=

y=1/2x

Answer:

I believe it would be zero

Step-by-step explanation:

Answer: When you divide by 100 you are essentially moving the decimal of the number two places to the left. In undoing this you would have to move the decimal of the number two places to the right.

28.003 would then turn into 2,800.3

Answer:

Options (2), (3), (5) and (6)

Step-by-step explanation:

Let the number of bicycles = x

and the number of treadmills = y

Since, number of new bicycles must be more than [tex]\frac{1}{3}[/tex] times of new treadmills,

Inequality representing the statement will be,

x > [tex]\frac{1}{3}[/tex]y

Each bicycle costs $340 and each treadmill costs $670.He must spend less than $5650,

Inequality will be,

340x + 670y < 5650

And the number of bicycles and treadmills should be greater than 0.

x > 0

y > 0

Therefore, constraints for this situation are,

Option (2)

Option (3)

Option (6)

Answer:

highest point is 229.20645 ft

yes it's a home run because at 410 ft the ball is at 81.802 ft which is way over the 8 ft fence.

Step-by-step explanation:

The maximum height achieved by the ball is 25.62 ft and it cannot be a home run because height of fence h(f) > 6.16 ft (vertical distance of ball at x = 410 ft).

A parabola is a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. A parabola can be represented with help of following equation -

y = a(x-h)² + k

Given in question is the equation representing path of the ball given by -

y = f(x) = - 0.0005x² + 0.2127x + 3.

Here, 'x' represents the distance from the home plate and 'y' is the height of the ball above the ground.

PART - 1 - Maximum height

Assume that -

a = - 0.0005

b = 0.2127

c = 3

So, we can write the given equation as -

y = ax² + bx + c

Now, differentiate it with respect to x, we get -

dy/dx = 2ax + b

For maximum height -

dy/dx = 0

2ax + b = 0

x = - b/2a

x = - 0.2127/ (2 x -0.0005) = 212.7 ft.

y[max] = - 0.0005 x (212.7)² + 0.2127 x 212.7 + 3.

y[max] = - 22.62 + 48.24 = 25.62 ft

PART - 2 - Vertical limits.

At horizontal distance of x = 410 feet, the vertical distance 'y' of the ball will be -

y [410] = - 0.0005 x (410)² + 0.2127 x 410 + 3.

y [410] = - 84.05 + 90.21

y [410] = 6.16

Height of the fence = 8 ft

Since, height of fence > 6.16 ft it cannot be home run.

Therefore, the maximum height achieved by the ball is 25.62 ft and it cannot be a home run because height of fence h(f) > 6.16 ft (vertical distance of ball at x = 410 ft).

Answer:

Write in slope-intercept form,  y = m x + b .

y  =  9 x  −  4

Step-by-step explanation:

Answer:

y =9x +4

Step-by-step explanation:

9x - y = 4

9x - y + (-9x) = 4 + (-9x)

-y = 4 - 9x

-y/-1 = (4-9x)/ -1

y = 9x +4

Answer:

3.04

Step-by-step explanation:

Mean = 3.34

Standard deviation= 0.4

n = 163

X ~ N(3.3, 0.4)

The cut off gpa = j

P(x>j) = 121/163

P(x<=j) = 42/163 = 0.26

O.26 represents the 26th percentile

We solve further by using Microsoft Excel. We use the function NORMINV on excel to get GPA

X =. NORMINV(0.26, 3.3, 0.4)

X = 3.04 approximately

We conclude that the required gpa is 3.04

Answer:

3.3 lb ≤ Weight ≤ 4.1 lb

Step-by-step explanation:

The options are not given; however, the question can still be solved.

Given

Weight = 3.7 lb

Range = 0.4 lb

The possible weight is calculated by (1) & (2) below

1. Maximum

Maximum = 3.7 lb + 0.4 lb

Maximum = 4.1 lb

2. Minimum

Minimum = 3.7 lb - 0.4 lb

Minimum = 3.3 lb

Hence, the range the weight of the apple can be is

3.3 lb ≤ Weight ≤ 4.1 lb

Answer:

shorter leg = 21 ft

longer leg = 28 ft

hypotenuse = 35 ft

Step-by-step explanation:

Let's call the longer leg of the triangle "b", the shorter leg "a", and the hypotenuse "h"

Then we have the following two equations:

a = b - 7

h = b + 7

And we can use the Pythagorean theorem to relate all three sides of the triangle:

[tex]h^2=a^2+b^2\\(b+7)^2=(b-7)^2+b^2\\b^2+14b +49=b^2-14b+49+b^2\\0=b^2-28b\\0=b*(b-28)[/tex]

Therefore there are two possible solutions to this equation: b = 0 or b = 28 ft.

So we take the one that is different from zero (since we are looking for the side of a triangle) That is: b = 28 ft

Then hypotenuse = 28 + 7 = 35 ft

and the shorter leg = 28 - 7 = 21 ft

Answer:

ratio of yards to minutes is;

900:10 or 90:1

Step-by-step explanation:

From research, the average person walks at around 3 miles per hour which approximately 1.5 yards/s.

Now, 60 seconds make a minute.

Which means in a minute, an average person will have walked; 1.5 × 60 = 90 yards/minute

Thus, in 10 minutes, average person will have walked; 90 × 10 = 900 yards

Thus, ratio of yards to minutes is;

900:10 or 90:1
