Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2
explanation
90+40=130
180-130= 50

4. On a 3-hour trip, a car travels 156 miles.
What is the average speed of the car on this
trip?
Answers
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.

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:

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 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
Answers
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.

49

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?
Answers
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
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)
Answers
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:

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?
Answers
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]

a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 3 hours and 45 minutes?
m(h) = 5.50h; $18.98
m(h) = [tex]\frac{h}{5.50}[/tex]; $0.68
m(h) = 3h + 45; $61.50
m(h) = 5.50h; $20.63

Answer:
For this case, the first thing we must do is define a variable:
h: number of hours worked.
We now write the equation that models the problem:
So, for 3 hours and 45 minutes we have:
Remember that we have the following conversion:
1 hour = 60 minutes
Substituting values:
Answer:
Crystal earns about:
m = $ 20,625
Step-by-step explanation:
Answer:
1) Required equation
2)Crystal earns $20.625 in 3 hours and 45 minutes.

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]
What is the 60th term 3, 7, 11, 15
Answers
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
