Find m
Geometry help pls

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

Answer:

So everyone here in Mrs. Futch?

Step-by-step explanation:

Step-by-step explanation:

You're only finding half of a circle but since you have 2, it is possible to just do the area of a circle which is [tex]\pi r ^{2} [/tex]

3.5 x 3.5 = 12.25

Because the radius of your circle is 3.5m but there are 2 of them you subtract 7 from 18 which give you 11:

Then you multiply 11 by 7.

= 77

Then add it all together.

[tex]a = (77 + 12.25\pi)m^{2} [/tex]

Answer:

8x-12

Hope it helped plz mark me brainliest PlzPlz

Answer:

8x-12

Step-by-step explanation:

You need to find a number/numbers that have the same variable if the variable is the same then you can add or subtract them

You can add 4x, 3x and 1x

4x plus 3x plus 1x is 8x

Since -12 is alone you can leave it as it is

8x-12

Answer:

18$

Step-by-step explanation:

The answer is 18$ because you multiply 3.60$ by 5 lbs

Answer:

Yes, its a function

Step-by-step explanation:

Answer: n=7+1/2

Step-by-step explanation:

We move all terms to the left:

2n+15-(30)=0

We add all the numbers together, and all the variables

2n-15=0

We move all terms containing n to the left, all other terms to the right

2n=15

n=15/2

n=7+1/2

Answer:

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Step-by-step explanation:

So first let's write a graph in vertex form with a vertex of (-5, -1)

We get

a(x+5)²-1

We now need to determine a

we know that when x= -2 y=2 which means we have

a(-2+5)²-1=2

Solve for a

a(3)²=3

9a=3

a=3/9

a=1/3

Now that we know what a is equal to we can write our equation

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Answer:

9,-5

Step-by-step explanation:

imagine the coordinate on a graph

if it helps draw a graph

Answer:

B.

Step-by-step explanation:

A is 10. B is 12. C (2^4) is 16. D is 3.14.... B (12) is the greatest.

Hope it helps!

Answer:

Transitive Property

Step-by-step explanation:

Since X is the midpoint, it bisects the points RS. If MX=XS, and RS is the same as XS, then they are the same. This also follows the Transitive propety  (if a=b and b=c, then a=c)

put in 75% for success rate

4 for the amount of trials because that is the total of kids the couple has

2 for number of successes for how many kids would get Type A blood

once calculated you get.21 or answer B

Answer:

0.00002237616

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.

Hope this helps :)

Answer:

x = ±9

Step-by-step explanation:

x² - 55 = 26

   +55   + 55

     x² = 81

     x = √81

     x = ± 9

Answer:

x = 9, -9

Step-by-step explanation:

x^2 - 55 = 26

x^2 = 81.

Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.

So, x = 9, -9

But thanks for the points.

Answer:

7.8 = k

Step-by-step explanation:

Since the figures are similar, we can use proportions

c           k

----- = -------

b            j

Substituting the values in

6.5         k

----- = -------

4          4.8

Using cross products

6.5 * 4.8 = 4k

31.2 = 4k

Divide each side by 4

31.2/4 = 4k/4

7.8 = k

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

Answer:

130°

Step-by-step explanation:

∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.
