$3,600
Step-by-step explanation:
You'd multiply 1,500 with .20 which equals 300. You'd then multiply 300 and 12 together to make $3,600.
Solve for x based on the following system of equations:
x + y = 5
2x + 3y = 20
-10
-5
-2
5
10
Answer:
x = -5
Step-by-step explanation:
x + y = 5 can be also written as 3x + 3y = 15 by times 3 on both side, let it be equation (1), then let 2x + 3y = 20 be equation (2), then use equation (2) - (1), can get (2x - 3x) + (3y - 3y) = 20 - 15 ---> -x = 5, then x = -5.
unos amigos compraron 1/2 de pizza hawaiana 2/4 de peperoni 1/2 de pollo y 3/4 de salchicha ¿cuanta pizza compraron en total?
Answer:
Los amigos compraron 2 pizzas más [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Para conocer la cantidad de pizza que los amigos compraron en total, debes sumar la cantidad de cada clase que compraron:
[tex]\frac{1}{2} +\frac{2}{4} +\frac{1}{2} +\frac{3}{4}[/tex]
Para sumar estos valores, debes encontrar un denominador común. Como 4 es múltiplo de 2, el 4 puede ser usado como denominador común. Este común denominador se divide entre el denominador de cada fracción. El resultado de la división se multiplica por el numerador de la misma fracción. Una vez que se divide y se multiplica, el resultado se coloca en el numerador. Realizando el mismo procedimiento con cada fracción y se realiza la suma con los numeradores que resultaron:
[tex]\frac{1}{2} +\frac{2}{4} +\frac{1}{2} +\frac{3}{4}=\frac{2+2+2+3}{4} =\frac{9}{4}[/tex]
Siendo [tex]\frac{9}{4} =2.25=2\frac{1}{4}[/tex], entonces los amigos compraron 2 pizzas más [tex]\frac{1}{4}[/tex]

What is the solution of 10(w + 3)= 70?
Answer:
The solution is w=4
simply
-30
divide by 10
Answer:
W=4
Step-by-step explanation:
1 0 ( + 3 ) = 7 0
1 0 + 3 0 = 7 0
Subtract 30 from both sides of the equation
simplify
10w=40
Divide both sides of the equation by the same term
10/40
W=4
A right square pyramid has a base with sides that are 2 inches in length and a slant height of 7 inches. If the lengths of the sides of the base and the slant height are multiplied by 7, by what factor is the surface area multiplied? A. 7 B. 14 C. 28 D. 49
Answer:
Step-by-step explanation:
base b = 2 in
slant height L = 7 in
lateral area = 4·½bL = 4·½·2·7 = 28 in²
base area = b² = 4 in²
surface area = 28+4 = 32 in²
If b = 14 and L = 49:
lateral area = 4·½·14·49 = 1372 in²
base area = 196 in²,
and surface area = 1372+196 = 1568 in²
The surface area has multiplied by 49.
Answer:
49

4. On a 3-hour trip, a car travels 156 miles.
What is the average speed of the car on this
trip?
Answer:
v = 52 mph
Step-by-step explanation:
Given that,
The distance travelled by the car, d = 156 miles
Time, t = 3 hour
We need to find the average speed of the car. The formula for the average speed is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{156}{3}\\\\v=52\ mph[/tex]
So, the average speed of the car is equal to 52 mph.

into...
Silvia's sister: 1 pages to ___ minutes
Find Unit Rate : 6/3= 2
Unit Rate for Silvia is 2
Written out : 3 pages x 2 = 6 minutes

Perform the indicated operation and state the domain. Let f(x) = 3x^1/3 and g(x) = 2x^1/2 Express as (f+g)(x)
Answer:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
[tex]x \ge 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^{\frac{1}{3}}[/tex]
[tex]g(x) = 2x^{\frac{1}{2}}[/tex]
Solving (a): (f + g)(x)
In functions:
[tex](f + g)(x) = f(x) + g(x)[/tex]
So, we have:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
Solving (b): The domain of f(x)
For (f + g)(x) to be defines, the value of x must be greater than or equal to 0.
Hence, the domain is:
[tex]x \ge 0[/tex]

In ΔRST, the measure of ∠T=90°, the measure of ∠R=67°, and TR = 94 feet. Find the length of RS to the nearest tenth of a foot......
Answer:
240.6 ft is your answer of your question.
Answer:
240.6 feetStep-by-step explanation:
to understand thisyou need to know about:trigonometryPEMDASlet's solve:to find x we will use cos function
[tex] \quad \: \cos( \theta) = \dfrac{adj}{hypo} [/tex]
substitute the value of [tex]\theta[/tex] and adj:
[tex] \quad \: \cos( {67}^{ \circ} ) = \dfrac{94}{x} [/tex]
cross multiplication:
[tex] \quad \: x\cos(67^{\circ})= 94 [/tex]
divide both sides by cos(67°) :
[tex] \quad \: \dfrac{x \cos( {67}^{ \circ} ) }{ \cos( {67}^{ \circ} ) } = \dfrac{94}{ \cos( {67}^{ \circ} ) } \\ \therefore \: x = 240.6[/tex]

A crate weighing 2400 N is lifted by a crane
to a platform 5.2 m above the ground. What
is the gravitational PE of the crate?
Answer:
12,480Joules
Step-by-step explanation:
GPE = mass * acceleration due to gravity * height
Since Force = mass * acceleration due to gravity
GPE = Force * Height
GPE = 2400 * 5.2
GPE = 12,480Joules
Hence the gravitational PE of the crate is 12480Joules

What is the 60th term 3, 7, 11, 15
Answer:
243
Step-by-step explanation:
Since this equation starts with 3 and increases by 4 every term we can construct an equation
y = difference * x + initial term
Our initial term is 3 and our difference is 4
y = 4x + 3
Now, we can input 60 for x
60 * 4 + 3 = 240 + 3 = 243

Step-by-step explanation:
Answer:
30 feet
Step-by-step explanation:
The ladder laying against the wall will create a right triangle.
The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.
You can use the pythagorean theorm so
[tex]a^{2} +b^{2} =c^{2}[/tex] so you plug in the values
[tex]18^{2}+24^{2} =c^{2} \\324+576=c^{2} \\900=c^{2} \\\sqrt{900} =\sqrt{c^{2} } \\30=c[/tex]
