find the value of x
(7x + 23)
(21x - 11)

Answer:

1.75

Step-by-step explanation:

h(t) = -16t² + 56t

h'(t) = -32t + 56

To find time at max height equate h' to 0

0 = -32t + 56

t = 56/32 = 1.75 s

It takes 1.75 s to reach max highest point

Answer:

a ≈ 22.184

Step-by-step explanation:

Using the Cosine rule in Δ ABC

a² = b² + c² - 2bc cosA

Here b = 15, c = 12 and A = 110° , then

a² = 15² + 12² - (2 × 15 × 12 × cos110° )

    = 225 + 144 - 360 cos110°

    = 369 - 360 cos110°

    = 492.12725.. ( take the square root of both sides )

a = [tex]\sqrt{x492.12725}[/tex] ≈ 22.184 ( to 3 dec. places )

Answer:

V≈100.5

Step-by-step explanation:

V=πr2h=π·22·8≈100.53096

Answer:

No, this is not a function. If you place the points, it will not pass the vertical line test. And, in a function, each x-coordinate has to have one y-coordinate. In this problem, there are two x-coordinates of 3, and they both have a different y-coordinate.

Answer:

Answer is A.

Step-by-step explanation:

x^2-15x-16

x^2+x-16x-16

x(x+1)-16(x+1)

(x+1)(x-16)=0

x=-1 and x=16

I'm pretty Shure it is x<5

here's something to help you-

Hope this helped :T

Answer:

x<5

Step-by-step explanation:

the arrow head pointed towards negative direction... and the unshaded circle shows that the value is less from that point...so the answer is x less than 5

Answer:

plug in the day to the equation:

November 1st is day 305, so November 24th would be day 328

y = 116.65 sin(0.02(328) +1.89) + 731.71

= 116.65 sin(8.45) + 731.71

= 828.247 minutes of daylight

≈ 13.8 hours or 13:48 (because .8 of an hour is ≈ 48 minutes)

Answer:

I need the whole question..

Have a nice day!

Answer:

Step-by-step explanation:

Answer:

1 1/2

Step-by-step explanation:

Step 1: convert 3 1/3 to improper fraction. Use thus rule a b/c=ac+b/c. 5 divided by 3x3x+1/3

step 2: simplify 3x3 to 9 5 divided by 9+1/3

Step 3: simplify 9+1 to 10. 5 divided by 10/3

Step 4: use the rule a divided by b/c=axc/b 5x3/10

Step 5: use this rule: axb/c=ab/c 5x3/10

Step 6: simplify 5x3 to 15 so 15/10

Step 7: simplify to 3/2

Last step: Convert to a mixed fraction.. Which would leave us with 1 1/2 or 1.5 in decimal form.

Hope this helps! :)

Answer:

NC = 4

Step-by-step explanation:

BC/MN = AC/AN

25/15 = AC/6

15AC = 25 × 6

3AC = 5 × 6

AC = 5 × 2

AC = 10

AN + NC = AC

6 + NC = 10

NC = 4

Respuesta:

4

Explicación paso a paso:

BC/AN

MN:AC

⇒25/x= 15/6                     {Multiplicación cruzada}

15x=150

⇒AC=10

∵NC= AC-AN

∴NC=10-6 =4

Answer:

about .24 mile per hour

1 mile is 5280 foot

Step-by-step explanation:

Answer:

678.58 ft^3

Step-by-step explanation:

V=πr2h/3

25.12/12.5663706 = 1.99898608

1.99898608 X 3 = 5.99695826

h= 6ft

6/2 = 3

6 * 3 = 18

V = π * 6^ * 18/3

V = 678.584013

Answer:

2x = 80. On dividing both sides by 2, we obtain. x = 40. x + 15 = 40 + 15 = 55. Hence ... Let the three consecutive multiples of 8 be 8x, 8(x + 1), 8(x + 2). Sum of ... Number after interchanging = 10 × 3x + x = 30x + x = 31x.

Answer:

33, 34, 35

Step-by-step explanation:

Semiprimes are the product of 2 prime numbers, then

11 × 3 = 33

17 × 2 = 34

7 × 5 = 35

Answer:

33,920 acres of forest were burned.

Step-by-step explanation:

In this case, since you know that a square mile is equal to 640 acres, you can use a rule of three to find the acres that are equivalent to 53 square miles:

    1 square mile    →    640 acres

53 square miles    →         x

x=(53*640)/1

x=33,920 acres

According to this, the answer is that 33,920 acres of forest were burned.

Answer:

FV = 60

Step-by-step explanation:

VG => 65 × 2 = 130

FH major arc=> 119 × 2 =  238

FH major arc -  GH = FG

FG => 238 - 168 = 70

VG - FG major arc = FV

FV => 130 - 70 = 60

Answer:

60 degrees

Step-by-step explanation:

The measure of an inscirbed angle is half the measure of the intercepted arc.

(The measure of the arc is twice the measure of the angle!)

The inscribed angle at V  intercepts an arc of 2 x 119 = 238 degrees, so the measure of arc FGH is 238.  Subtract arc GH from that, 238 - 168 = 70, so that is the measure of arc FG.

The angle at H intercepts an arc with measure 2 x 65 = 130.  The measure of arc VFG is 130.  But arc FG is part of that, so subtract its measure from 130.  130 - 70 = 60.

The measure of arc FV is 60 degrees.

Answer:

8,100

Step-by-step explanation:

To get the area of a square you must multiply one length by width 90 x 90 = 8100

The area of the infield with each side 90 feet long is,

⇒ Area of the infield = 8100 feet²

The multiplication means to add or sum a number to itself a particular number of times. And, The Multiplication can be viewed by a process of repeated addition.

We have to given that;

The infield of a baseball diamond is shaped like a square.

And, Each side is 90 feet long.

Hence, The area of the infield is,

⇒ Area of the infield = side²

Here, We have;

Side of infield = 90 feet

Hence, We get;

⇒ Area = 90²

⇒ Area = 90 x 90 feet²

⇒ Area = 8100 feet²

Therefore, We get the correct answer is;

The area of the infield with each side 90 feet long is,

⇒  Area of the infield = 8100 feet²

Answer:

Looks like holographic glitter to me

37 inches

Hope this helps!

Answer:

Yes.

Step-by-step explanation:

If the side lengths verify in the Pythagorean theorem, then it is a right triangle.

a² + b² = c²

15² + 20² = 25²

225 + 400 = 625

625 = 625

Since these values come out true when using the Pythagorean Theorem, this triangle is a right trinagle.

Answer:

4 quarts

Step-by-step explanation:

1 cup = 8 ounces

quart = 2 cups

So this is easy => just do 64/8 which is 8 cups

-------------------------------------------------------------

Then, you do 8 cups/2 to make quarts.

so answer is 4 quarts :)

Step-by-step explanation:

The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.

Answer:

Yes it is a right angled triangle.
