What is the area of this figure?​

Answer:

16 is your Correct answer. Thanks.

Answer: [tex]4x+23[/tex]

Step-by-step explanation:

Given

The length of the bottom of the triangle is x

Another side is [tex]2x+13[/tex]

The last side is [tex]x+10[/tex]

Perimeter is the sum of the side of triangles

[tex]\Rightarrow \text{Perimeter}=x+2x+13+x+10\\\Rightarrow \text{Perimeter}=4x+23[/tex]

Answer:

6x + 20

Step-by-step explanation:

the formula for the perimeter of the rectangle is 2 x (length + width)

from the question length = 2x

width = 10 + x

2(2x + 10 + x)

2 (3x + 10 )

6x + 20

Answer:

8 minutes cause 32/8 = 4  then 4 x 2 = 8

Step-by-step explanation:

9514 1404 393

Explanation:

We have to assume the triangle is a right triangle.

In a 30°-60°-90° right triangle the side lengths have the ratio ...

  short side : long side = 1 : √3

This lets you write the proportion ...

  x/15 = 1/√3

Multiplying by 15 gives ...

  x = 15/√3 . . . . . . matching choice D

__

There are other ways to get there. One of them is ...

  x = 15·tan(30°) = 15/√3

Answer:

Step-by-step explanation:

h(t)=-16t^2+48t+4

dh/dt=-32t+48

d2h/dt2=-32

Since acceleration is always negative when the velocity, dh/dt=0, it will occur at the maximum height.

dh/dt=0 when

-32t+48=0

-32t=-48

t=1.5 seconds

Without calculus, the vertex of a parabola will be at -b/(2a) of the quadratic equation. In this case

-48/(2(-16))

-48/-32

1.5 seconds

step 1: plot your points.

step 2: find the rise over run

step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)

step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)

then put in y intercept form: y=2/5x+8

According to the table,

it should be (5,9) and (8,10.5)

Answer: $1,280

Step-by-step explanation:

The refund one a gallon is 50% of the cost of the gallon which is $0.32.

The refund on a gallon is:

= 50% * 0.32

= $0.16

If it was for 8,000 gallons the refund would be:

= 8,000 * 0.16

= $1,280

Answer:

t ≈ 44.43 hours

Step-by-step explanation:

Expression that models the population of a bacteria after time 't' is,

N(t) = [tex]250(e^{0.0156t})[/tex]

Here initial population = 250

And N(t) = Population after 't' hours

t = duration

We have to find the duration in which bacterial population gets doubled.

N(t) = 2×250 = 500

From the given expression,

500 = [tex]250(e^{0.0156t})[/tex]

[tex]e^{0.0156t}=2[/tex]

[tex]\text{ln}(e^{0.0156t})=\text{ln}(2)[/tex]

0.0156t[ln(e)] = 0.693147

0.0156t = 0.693147

t = [tex]\frac{0.693147}{0.0156}[/tex]

t = 44.432

t ≈ 44.43 hours

Answer:

15

Step-by-step explanation:

distance formula = square root of difference of y-values subtracted by difference of x-values

d = [tex]\sqrt{144+81}[/tex] = 15

Answer:

Step-by-step explanation:

d^2=dx^2+dy^2

d^2=(-3+12)^2+(15-3)^2

d^2=81+144

d^2=225

d=15

Answer:

Step-by-step explanation:

CA and CB are both opposite equal 90 degree angles so are equal so we can say

8x-12=4x

4x-12=0

4x=12

x=3, since CA=4x

CA=4(3)=12

Answer:

Step-by-step explanation:

Prime factorization requires dividing by primes starting with smallest prime number

402/2=201

201/3=67, 67 is prime so we cannot go further so the prime factorization of 402 is

2X3X67

Answer:

yes, it is a right triangle.

Step-by-step explanation:

you could use the pythagorean theory to check:

[tex]a^{2} + b^{2} = c^{2}[/tex]

(the hypotenuse is the longest side)

[tex]17.5^{2} + 6^{2} = 18.5^{2}[/tex]

[tex]306.25 + 36 = 342.25[/tex]

[tex]342.25 = 342.25[/tex]

Answer:

50

Step-by-step explanation:

Wen: 30% of the total number of cards = 60 cards

Set this up as an equation

30/100 = 60/x

Cross multiply

30 × x = 100 × 60

30x = 6000

Divide both sides by 30 to isolate the variable

x = 200

There are 200 cards total

Gina: 25% of the total 200 cards

Set this up as an equation

25/100 = x/200

Cross multiply

25 × 200 = 100 × x

5000 = 100x

Divide both sides by 100 to isolate the variable

50 = x

Gina's share is 50 cards

Answer:

The most feasible answer would be the first option - 47

Step-by-step explanation:

This is true because if we look at the triangle it looks as if the sides have equal length, but if we look closely we will notice that the b side is angled more by a slight inch, compared to the other side, thus your answer should be 47 - the first option
