Answer:

3x and 8x

Step-by-step explanation:

They both share the same variable unlike 8 and 3y which have different variables. Once simplified, the expression should equal 11x + 8 + 3y

Answer:

3x and 8x

You see 3x and 8x are both like terms because they both have x

but..

The other 3 does not have a x it has a y

Answer:

X= 12

Step-by-step explanation:

36/5x =3/5(cross multiplication)

180=15x

divide by 15 both sides

X = 12

Answer:

the answer would be $128.40

Step-by-step explanation:

7% times 120 is 8.4

8.4 plus 120 is 128.4

The amount to be pay for coat is $128.4

Step-by-step explanation:

Given:The sales tax rate is 7.25% in California.

The cost for a coat in Los angeles is $120.00.

Now, to find amount to be paid.

Sales tax = 7.00%.

Cost = $120.00.

So, amount to be paid = $120 + 7.00% of $120.00.

[tex]=120+\frac{7.00}{100} *120\\=120+\frac{84}{10} \\=120+\frac{42}{5} \\=128.4!![/tex]

Therefore, the amount to be pay for coat is $128.4

Answer:

Option A

Step-by-step explanation:

Given expression is [tex]\sqrt[3]{56x^7y^5}[/tex].

[tex]\sqrt[3]{56x^7y^5}=(56x^7y^5)^{\frac{1}{3}}[/tex]

              [tex]=[(2)^3(7)(x^2)^3(x)(y)^3(y)^2]^{\frac{1}{3}}[/tex]

              [tex]=[(2)^{\frac{3}{3} }(7)^{\frac{1}{3} }(x^2)^{\frac{3}{3} }(x)^{\frac{1}{3}}(y)^{\frac{3}{3} }(y)^{\frac{2}{3} }][/tex]

              [tex]=3x^2y[(7)^{\frac{1}{3}}(x)^{\frac{1}{3}}(y^2)^{\frac{1}{3}}][/tex]

              [tex]=3x^2y\sqrt[3]{7xy^2}[/tex]

Option A is the correct option.

Answer:

The bearing of B from C is 22° counterclockwise

Step-by-step explanation:

∠CAB = 210 - 90 = 120°

Extend a line from A to the west.

drop a perpendicular line from that line to point C.

Let's call the point at the perpendicular point, M.

∠MAC = 180° - 120° = 60° because they are supplementary.

Now we have a right ∠CMA with a known hypotenuse and a known angle.

Solve for MA:

cos 60° = MA/3.8 = 1.9

Solve for MC:

sin 60° = MC/3.8 = 3.29

MB = 1.9 + 6.4 = 8.3

tan ABC = 3.29/8.3 = 21.62°

Answer:For the cube root function f(x)=3√x f ( x ) = x 3 , the domain and range include all real numbers. Note that there is no problem taking a cube root, or any odd-integer root, of a negative number, and the resulting output is negative (it is an odd function).

Step-by-step explanation:

The domain and range for all cube root functions is set of all real numbers.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

The domain of a cube root function f (x) = ∛x is the set of all real numbers (R) because it can be calculated for all values of x. Its range is also equal to the set of all real numbers because it will result in all real numbers as y-values.

The range of a cube root function is all real numbers except for 0.

Therefore, the domain and range for all cube root functions is set of all real numbers.

The required expression for climbing the rock formations is given as y = 95x + 25.

Given,

[x]Climb Height (feet) Time (minutes)(y)

1                120

2               215

3               400

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
The standard linear equation is given as,
y -y₁ =(y₂ - y₁) /  (x₂ - x₁) (x - x₁)

put the values from the data table,

y - 120 = [(215-120)/(2-1)](x - 1)
y = 95(x - 1) + 120
y = 95x - 95 + 120
y = 95x + 25

Thus, the required expression for climbing the rock formations is given as y = 95x + 25.

#SPJ3

i am garbage dont listen to the old answer

Answer:

Son is 3. Father is 33.

Step-by-step explanation:

Let the present age of the son be 'x' years.

Then father's age will be (x + 30) years

Given : After 12 years, the father will be three times as old as his son. Therefore,

(x + 12)3 = x + 30 + 12

3x + 36 = x + 42

3x - x = 42 - 36

2x = 6

x = 3

The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.

Answer:

x=65°

Answer:36 in

Step-by-step explanation:

The formula for circumference is: C = 2πr

π = 3.14

r = radius.

The Circumference given to us is 72π. Plug in 72π for C

72π = 2πr

Isolate the variable, r. Divide 2 and π from both sides

(72π)/2π = (2πr)/2π

r = (72π)/2π

r = 36

36

Answer: 72

Step-by-step explanation:

since the formula of circumference is C= Pi times the diameter, In some cases when they don't say what Pi is same thing here. So, you would put the diameter and the pi sign next to each other. So 72 is the diameter.

Answer:

The time it would take to fill up the truck is approximately 344 minutes

Step-by-step explanation:

The given parameters of the truck are;

The volume of the water truck, V = 1,200 gallon

The rate at which water flows from the hose. m = Constant rate

The volume of water in the truck after t₁ = 10 minutes is V₁ = 65 gallons

The volume of water in the truck after t₂ = 15 minutes is V₂ = 82 gallons

Therefore, the rate at which water flows from the hose to the truck, 'm', is given by the equation for the slope of a straight (constant variation) line, as follows;

[tex]m = \dfrac{V_2 - V_1}{t_2 - t_1}[/tex]

Therefore, we have;

[tex]m = \dfrac{82 \, gallons - 65 \, gallons}{15 \, minutes - 10 \, minutes} = 3.4 \, gallons/minute[/tex]

The point and slope form of the straight line equation relationship between the volume in the tank and the time of flow is given as follows;

V - 82 = 3.4 × (t - 15)

Therefore, the slope and intercept form of the equation is given as follows;

V = 3.4·t - 15 × 3.4 + 82 = 3.4·t + 31

∴ V = 3.4·t + 31

When the tank is filled, V = 1,200 gallons, therefore, we have;

1,200 = 3.4·t + 31

3.4·t = 1,200 - 31 = 1,169

t = 1,169/3.4 = 5845/17 = 343.[tex]\overline{8235294117647058}[/tex]

The time it would take to fill up the truck, t = 343.[tex]\overline{8235294117647058}[/tex] minutes ≈ 344 minutes.

Step-by-step explanation:

cosФ = opp/hyp     sinФ = adj/hyp        hyp = 10      perimeter = a + b + c

for the 45° right triangle

a = b     so      2a² = hyp²                       perimeter 45 = a + a + hyp    

P45 = 2a + hyp         a = sin(45) (hyp)  = [1/2√2)] (hyp)        sin(45) = (√2)/2

P45 = 2([1/2√2)] (hyp) + hyp

P45  = hyp (√2 + 1)

for the 30° right triangle

a = hyp×sin(30)     b = hyp×cos(30)           perimeter 30 = a + b + hyp    

            sin(30) = 1/2       cos(30) = (√3)/2

a  = hyp(1/2)           b = hyp(1/2)(√3)

P30 =        a        +      b         + hyp

        =  hyp(1/2)  +  hyp(1/2)(√3) + hyp

        =  hyp[ 1/2  +  (1/2)√3  + 1]

        =  hyp[ 1/2  +  (1/2)√3  + 1]             factored out the hyp

        =  (1/2)hyp[ 1 + √3 + 2]                  factored out a 1/2

P30  =  (1/2)hyp[ 3 + √3]

which is greater  P45 or P30?   vso I set both perimeters equal to each other

              P45           vs             P30

      hyp (√2 + 1)     =    (1/2)hyp[ 3 + √3]            the hyp cancel

               (√2 + 1)     =    (1/2)[ 3 + √3]                    still tough to tell  needed

               1.414 + 1    =    (1/2)[ 3 + 1.732]                to go to the calsulator
