If x^2 =2” what is the value of x

Answer:  B. 30 square units

Step-by-step explanation:

Area of triangle formula is base x height divided by 2 so we do 15 * 4 = 60/2 = 30 units

Answer:

42

Step-by-step explanation:

We know that 10x + 6y = 7, and so

6(10x + 6y) = 6(7) = 42

Step-by-step explanation:

I just followed the answer sheet

Answer:

$13.05

Step-by-step explanation:

Given: Mark and his 3 friends = 4 Total cost = $52, percent off: 20%

To find: How much each person would pay if they split the bill evenly.

Solution:

Firstly, since they left the server a 20% tip, multiply 20% by the total cost. Convert it to a fraction. Note: you're adding 20% to the total cost.

                                                    [tex]\frac{20}{100}[/tex] + [tex]\frac{52}{1}[/tex]

                                                      = [tex]_{52.2}[/tex]

Now, that is done, let's divide the newly found cost by the four friends.

                                                     [tex]\sqrt[4]{52.2}[/tex]

                                                   = [tex]{13.05}[/tex]

So, they would pay $13.05 evenly.

Answer: 90 mm cubed

Step-by-step explanation:

Formula = (L*W*H) / 2

5 * 12 * 3 = 60 * 3 = 180

180 / 2 = 90

Answer: 30 boys 45 girls

Step-by-step explanation:

Answer:

2.5

Step-by-step explanation:

The radius is any line from the middle of the circle to the end of the circle. The diameter is a chord which is a line going from any end of the circle to the other end but the diameter crosses though the point which is in the middle.

So, you split the diameter in half. 5/2 = 2.5

Answer:

The answer is 49

Step-by-step explanation:

Rate of change=  (f(b)-f(a))/(b-a)

a = 3 and b = 5

Rate of change = (125-27)/(5-3)

= 49

Answer:

12

0.6/0.05

(0.6 x 100) / (0.05 x 100)

= 60/5 = 12

Step-by-step explanation:

number of pieces = total weight of the cheese / weight of each piece

0.6 / 0.05

to divide easily, convert the decimals to whole number by multiply both the denominator and numerator by 100

(0.6 x 100) / (0.05 x 100)

= 60/5 = 12

Answer: 3j-6k+4

Step-by-step explanation:

First you have to distribute the 3 to the j and the -2k since they are both in the parentheses. So it would look like (3*j) +(-2k*3)+4 and if you simplify that it is 3j-2k+4. After that there are no like terms so that is your answer.

Answer:

167.36 weeks

Step-by-step explanation:

Given: Currently has $180, the cost is $860, and he plans to save $68 a week

To find: How many weeks will it take to save his money

Solution: If Barry currently has $180 and needs $860 for his tires also saves $68 a week, divide the amount he wants to save by the amount he saves a week, to find how many weeks will it take to save his money

                                          860 ÷ 68 = 12.64

Subtract 180 because he already has $180 saved currently

                                           180 - 12.64 = 167.36

Hence, it will take approximately 167 weeks to save his money up to $860

Answer:

[tex]Domain : 0\le x \le 6[/tex]

[tex]Range: 0 \le y \le 72[/tex]

Step-by-step explanation:

Given

See attachment for complete question

Required

Determine the domain and the range

From the complete question, we understand that the study was carried out for 6 days. This represents the domain;

So, we have:

[tex]Domain : 0\le x \le 6[/tex] i.e. from day 0 to day 6

Also, he experimented with 72ml, and he used an equal amount each day before he used up all the 72mL. This represents the range

So, the range is:

[tex]Range: 0 \le y \le 72[/tex] i.e. from 72mL to 0mL

Answer:

x ≈ 12.9

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{x}[/tex] ( multiply both sides by x )

x × tan35° = 9 ( divide both sides by tan35° )

x = [tex]\frac{9}{tan35}[/tex] ≈ 12.9 ( to the nearest tenth )

Answer:

P = 38

Solution

P=a+b+c=15+8+15 = 38

PLZ GIVE BRAINLIESTTTTT

Answer:

1/676

Step-by-step explanation:

In a deck of cards there are 2 red 8's ( 8 of diamonds and 8 of hearts)

P( red 8)  = number of red 8's/ total

               = 2/52 = 1/26

Then we put the card back so there are still 52 cards

In a deck of cards there are 2 black 10's ( 10 of spades and 10 of clubs)

P( black)  = number of black 10's/ total

               = 2/52 = 1/26

Multiply the probabilities together

P( red 8, black 10) = 1/26 * 1/26 = 1 /676

Answer:

8 11/100

Step-by-step explanation:

8.11 is the same thing as 8 whole numbers and since the .11 is in the hundreths place, it becomes 11/100.

Answer:

J' = (-15, -10)

K' = (5, 20)

L' = (20, 10)

Step-by-step explanation:

Given the coordinates J(–3, –2), K(1, 4), and L(4, 2)

D5(ΔJKL) means we need to dilate the coordinates by a constant of 5

To do that, we will multiply the coordinates by a value of 5

D5(ΔJKL)

J' =  (5(–3), 5(–2)),

J' = (-15, -10)

K' = (5(1), 5(4))

K' = (5, 20)

L' = (5(4), 5(2))

L' = (20, 10)

Distance between Kalamazoo and Ann Arbor is 152 kilometers (94 miles).

Answer:

Distance between Kalamazoo and Ann Arbor is 152 kilometers (94 miles).

1 hr 36 min (98.3 mi)

Step-by-step explanation:

Answer:

a) x=3

b) z=10

c) P= 2

d) X=7

e) U=1

Step-by-step explanation:

Resolver una ecuación consiste en hallar los valores de la variable que hacen cierta la igualdad.

a) 2x= 6

El coeficiente es el número junto a la variable. En este caso, el coeficiente es 2. Para eliminar este número en la expresión 2x, debido a que la variable x esta multiplicada por 2, deberás dividir ambos lados de la ecuación entre 2, debido a que la operación opuesta de la multiplicación es la división.

(2x)÷2=6÷2

x= 3

Comprobar la solución de una ecuación se hace al remplazar la variable en una ecuación con el valor de la solución. La solución debería satisfacer la ecuación cuando se ingresa en esta.

En este caso:

2*3= 6

6=6

b) 10 + z= 20

En este caso se debe sumar o restar la constante que se encuentra acompañando a la variable en ambos lados de la ecuación de manera de aislar el término de la variable. En este caso:

10 - 10 + z= 20 -10

z= 10

Comprobación:

10 + z=20

10 + 10=20

20=20

c) P + 9= 11

P +9 - 9= 11 -9

P=2

Comprobación:

2 + 9= 11

11=11

d) 3X + 8 = 29

En este caso, se suma o resta la constante en ambos lados de la ecuación y luego se elimina el coeficiente de la variable mediante la división o multiplicación. Esto es:

3X + 8 - 8= 29 - 8

3X= 21

3X ÷3= 21÷3

X=7

Comprobación:

3*7 + 8=29

21+8=29

29=29

e) 2U + 8= 10

2U + 8 - 8= 10 -8

2U= 2

2U ÷2= 2÷2

U=1

Comprobación:

2*1 + 8= 10

2 + 8= 10

10=10

Answer:

C) SSS

Step-by-step explanation:

SSS stands for "side, side, side" and means that we have two triangles with all three sides equal.  

If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
