Justin is 74 inches and casts a shawdow that is 102 inches long. At the same time , a tree casts a shadow that is 39 feet long. How tall is the tree to the nearest foot?

Answers

Answer:

The tree is 28 feet in height.

Step-by-step explanation:

This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.

74 / x = 102/39           Cross Multiply

102x = 74*39              The inches as a unit cancel out.

102x = 2886               Divide by 102

x = 2886/102

x = 28.29 feet

Step-by-step explanation:

Hopefully this helps you,
So if A= 70 degrees, C will also 70 degrees.
The parallelogram will always equal 360 degrees, so 70(2) = 140.
Then 360 - 140 = 220.
Then divide 220 by 2, so 220/2 = 110.
Therefore angles B and D are 110 degrees.
So your answer,
C = 70 degrees
B and D = 110 degrees

Round 4,276 to the nearest hundred.

Answers

When rounding a number such as 4276 to the nearest hundred, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

In this case, Rule A applies and 4276 rounded to the nearest hundred is:

Help

Answers

Answer:

see below

Step-by-step explanation:

1. x-9=-17-simplifies to a single solution-one solution

2.x+4=4+x-same thing on each side-infinite solutions

3. 0.4x=0.4x+2-same variable coefficient plus a number-no solutions

4. 5x=5x-3-same as above-no solutions

5. 5x=2-variable on one side, constant on another-one solution

6. x-5=x-5-same thing on each side-infinite solutions

7.3x=3x-same thing as above-infinite solutions

8.8x-10=8x-same coefficient for each variable plus a constant-no solutions

Answer:

One solution:

x + 9 = -17

5x = 10

No solution:

0.4x = 0.4x +2

5x = 5x - 3

8x - 10 = 8x

Infinite solutions:

x + 4 = 4 + x

x - 5 = x - 5

3x = 3x

Step-by-step explanation:

x + 9 = -17

  - 9     -9

x = -26 (one solution)

x + 4 = 4 + x

  - 4   - 4

x = x (infinite solutions)

0.4x = 0.4x +2

-0.4x  -0.4x

0 = 2 (no solution)

5x = 5x - 3

-5x  -5x

x = 5 (one solution)

x - 5 = x - 5

 + 5       + 5

x = x (infinite solutions)

For this case we can model the problem as a rectangle triangle.

 We know:

 Length of the hypotenuse

 Angle between the base of the triangle and the hypotenuse.

 We want to know:

 Length of the base.

 For this we use the following trigonometric relationship:

 cos (15) = \frac{x}{500}cos(15)=500x

 Clearing x we have:

 x = 500 * cos (15) x = 482.96x=500∗cos(15)x=482.96

Julian forgot his bat when he left for baseball camp. His mother finds a box to ship it to him with the dimensions shown. If the bat measures 34 inches long, will the bat fit inside the box? Drag words to complete the statements about the diagonal of the base and the interior diagonal of the box. Words may be used once, more than once, or not at all.


Here are the words shorter than longer than equal to will not

The diagonal of the base of the box is

The length of the interior diagonal of the box is

Answers

The bat will fit in the box if the length of the bat is less than the interior diagonal of the box

Julian's bat will not fit inside the box

How to determine if the bat can fit the box?

From the complete question, the dimension of the box is:

32 in by 6 in by 8 in

Start by calculating the diagonal (d) of the base of the box using the following Pythagoras theorem

[tex]d^2 = 6^2 + 8^2[/tex]

Next, calculate the length of the interior diagonal of the box.

[tex]L = \sqrt{32^2 + d^2\\[/tex]

This gives

[tex]L = \sqrt{32^2 + 6^2 + 8^2}[/tex]

Evaluate

[tex]L = 33.53[/tex]

The length of the bat (34 inches) is greater than the interior diagonal of the box (33.53 inches)

Hence, the bat will not fit inside the box

Answers

Answer:

1.[tex]y=2x+4[/tex]
2.[tex]y=1x+3[/tex]

Step-by-step explanation:

Given the following questions:

Question one:

Point A = (-1, 2) = (x1, y2)
m = 2

To find the answer we will use the formula to find the slope intercept, substitute the values and then solve for b.

[tex]y=mx+b[/tex]
[tex]m=2[/tex]
[tex]x=-1[/tex]
[tex]y=2[/tex]
[tex]2=2(-1)+b[/tex]
[tex]2\times-1=-2[/tex]
[tex]2=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]2+2=4[/tex]
[tex]4=b[/tex]
[tex]b=4[/tex]
[tex]y=2x+4[/tex]

The slope intercept form of the line that passes through (-1, 2) and has a slope of 2 is "y = 2x + 4."

Question two:

Point A = (-1, 2) = (x1, y1)
Point B = (2, 5) = (x2, y2)

To find the slope intercept form we must first find the slope using the formula to calculate slope or rise over run.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{5-2}{2--1}=\frac{3}{3}[/tex]
[tex]3\div3=1[/tex]
[tex]m=1[/tex]

Now that we have the slope, we will use the formula for slope intercept, substitute the values, then solve for b.

[tex]y=mx+b[/tex]
[tex]m=1[/tex]
[tex]y=2[/tex]
[tex]x=-1[/tex]
[tex]2=1(-1)+b[/tex]
[tex]1\times-1=-1[/tex]
[tex]2=-1+b[/tex]
[tex]-1+1=0[/tex]
[tex]2+1=3[/tex]
[tex]3=b[/tex]
[tex]b=1[/tex]
[tex]y=1x+3[/tex]

The line that passes through the points (4, -2) and (2, 5) in slope intercept form is indeed "y = 1x + 3."

Hope this helps.

For which values of c does the quadratic equation x^(2)-2x+c=0 have No real roots?

Answers

Answer:

c > 1

Step-by-step explanation:

Given equation: [tex]x^2-2x+c=0[/tex]

General form of quadratic equation: [tex]ax^2+bx+c=0[/tex]

We can use the discriminant to determine the value of c for which the equation has no real roots.

[tex]b^2-4ac < 0\implies \textsf{no real roots}[/tex]

From the given equation:

[tex]a=1[/tex][tex]b=-2[/tex][tex]c=c[/tex]

Inputting these values into the discriminant formula:

[tex]\implies (-2)^2-4(1)(c) < 0[/tex]

[tex]\implies 4-4c < 0[/tex]

[tex]\implies 4 < 4c[/tex]

[tex]\implies 1 < c[/tex]
