2a+3/2 - a-2/3 = a-1/4

Answer:

B

Step-by-step explanation:

Just factor it:

5(42 - 12) = 5(30)

Answer:

B

Step-by-step explanation:

Given

5(42) - 5(12) ← factor out 5 from each term

= 5(42 - 12)

= 5(30)

Thus 30 completes the equation

Answer:

26 square meters (the first option)

Step-by-step explanation:

The area of a trapezoid is (b1+b2)/2*h.

b1=one of the bases (one of the bases that are parallel to each other)

b2= the other base (that is parallel to base 1)

h=height

In this picture, b1=5, b2=8, h=4

So, the area is

(5+8)/2*4

=13/2*4

=6.5*4

= 26 square meters

Answer:

C. Brandon. He has a 0.63 probability of attending both activities.

Step-by-step explanation:

                 Probability of attending     Probability of attending

                 the Saturday activity          the Sunday activity

Aisha                     0.90                                  0.68

Brandon                 0.71                                  0.89

Given that attendance at one activity is independent of  attendance at the other, the probability that Aisha attends both activities is: 0.9*0.68 = 0.61, and the probability that Brandon attends both activities is: 0.71*0.89 = 0.63

Brandon has a 0.63 probability of attending both activities.

The correct option is (C).

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

                Probability of attending     Probability of attending

                            ( Saturday)                    ( Sunday )

Aisha                     0.90                                  0.68

Brandon                 0.71                                  0.89

As,  attendance at one activity is independent of attendance at the other activity.

P( Aisha attends both activities)

=0.9*0.68

= 0.61,

P(Brandon attends both activities)

= 0.71*0.89

= 0.63

Hence, Brandon. He has a 0.63 probability of attending both activities.

Step-by-step explanation:

y = 1/2x

Substitute the points into the equation and see if it is true

If it is true it is on the line

(0,0)

y = 1/2x

0 = 1/2(0)

0=0 true

The diameter is 60 feet, so the radius is half that at 60/2 = 30 feet.

Plug r = 30 into the formula below and simplify

V = (4/3)*pi*r^3

V = (4/3)*pi*(30)^3

V = (4/3)*pi*27000

V = (4/3)*27000*pi

V = 36000pi

Answer:

The average speed on the second part was 30 mph.

Step-by-step explanation:

The whole trip between New York and Washington is 120 miles. On the first part he drove at 50 mph for 1.5 h, from 7 AM to 8:30 AM, therefore he drove a distance of:

distance = speed*time = 50*1.5 = 75 miles

So the second part had a length of 120 - 75 = 45 miles. With an elapsed time of 1.5h, therefore the average speed was:

speed = distance / time

speed = 45 / 1.5

speed = 30 mph

The average speed on the second part was 30 mph.

Answer:

The current is approximately 8.571 Amps

Step-by-step explanation:

You are supposed to use Ohm's Law for this problem.

Recall that Ohm's Law gives you the relationship between voltage applied (V), resistance (R) and current (I):  

[tex]V=I\,*\,R[/tex]

If the units of resistance are ohms, and the voltage is in volts, the current will be given in Amps (amperes). Then solving for the current (I) in the above equation:

[tex]I=\frac{V}{R} \\I=\frac{120}{14} \\I=8.571\,\,Amps[/tex]

Deniz, as he would be correct because those images of the embryos were classified as fraud, so Malik's theory could not be true in the first place becuase the images are not based on reality, but the pictures that Deniz are using as the backup for his theory are true so his statement would be true...

idk if your school can take that as an answer but that is the truth, so just in case here is an alternate answer

Deniz because the only time the organisms are similar in appearance is for a short period of time, then they drastically change in appearance, never to share common characteristics again, if they were from the same ancestor they would all have characteristics pointing to each other and there ancestor

You have to count the number of dots there are after the number 8. (This includes the dotes above 8.)

Answer:

9 students

Step-by-step explanation:

Assuming that these dots represent students, let us begin with the amount of students that answered 8 questions right;

Students who got 8 answers right ⇒ 4 students,

Students who got 8 answers right ⇒ 3 students,

Students who got 10 answers right ⇒ 2 students

Now we are to compute the value of the students who received 8 or more answers right, provided the questions are out of 10;

Students who received 8 or more answers right; 4 + 3 + 2 = 9 students

Solution; 9 students

  oh god idk

2. he would have to get 100% because 90+90=180 and 180-80-100 and so 100+80=180 and 180/2=90 so 100%

3. 92.6 because 90+98+96+94+85=463 and 463/5=92.6 and 463+92.6=555.6 and 555.6/6 is 92.6 which is ultimately 92

4. idk understand stem and leaf plots but this is how you find a median

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Answer: I’d the circumference is 6 it would be 6 x 3.14

Step-by-step explanation:

Answer:

$54

Step-by-step explanation:

10 percent of 60 is 6 and thats because 60 times 10 percent is 6 so $60-$6=$54

Answer:

6900000 + (6900000 * x) = 7400000

This equation is telling us 6900000 plus 6900000 times a specific percent will get you 7400000, which is what you want.

6900000 + (6900000 * x) = 7400000

6900000 + 6900000x = 7400000

Subtract 6900000 from both sides.

6900000x = 500000

Divide both sides by 6900000

x = 0.0724637681, or .07 when rounded to the nearest tenth.

convert .07 to a percentage by moving the decimal point two places to the right.

.07 = 7%

The sales of the children's athletic shoes rose about 7%

Answer:

1- longest side

2- adjacent and opposite

3-a^2 + b^2 = c^2

4- yes, by using pythagorean theorem

Step-by-step explanation:

1- the hypotenuse is always the longest side

2- the three sides are called hypotenuse, adjacent and opposite

3- a^2 + b^2 = c^2 is a formula to solve for missing legs

4- pythagorean theorem (a^2 + b^2 = c^2) is the formula to solve for missing legs/hypotenuse . A and B represents a leg and c will always be the hypotenuse, you then isolate for the letter you are missing

Answer:

9.1924

Step-by-step explanation:

if you make a model the 13 foot ladder is the hypotenuse and the height off the ground is the opposite. so you would you sin. this is what the equation would look like. sin(45)=x/13

now just multiply 13 to sin(45)

*i know it says to use y=13cos but i don't see why you would use that to find the height of the wall, but I might be wrong on how to do it, this is just how I learned and is what my level of math is.

Answer:

x = 118.572091090591

Step-by-step explanation:

we are given a right triangle then

tan(16) = 34/x

then

x = 34÷tan(16)

  =118.572091090591

Info :

tan(16) = 0.286745385759

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

4/5 >-2/3d

Switch sides:

-2/3d < 4/5

Multiply both sides by -1:

(reverse the inequality)

(-2/3d)(-1) < 4/5 (-1)

Simplify:

2/3d > -4/5

Multiply both sides by 3:

3* 2/3d > 3(-4/5)

Simplify:

2d > -12/5

Divide both sides by 2:

2d/2 > -12/5/ 2

Simplify:

d > -6/5

Your Answer As A Fraction Is d > -6/5

Your Answer As A Decimal Is d > -1.2
