Answer:
The slope is 9/1 or just 9.
Step-by-step explanation:
I used the y1-y2/x1-x2 slope formula.
Type the slope of the line PERPENDICULAR to y = 6x -3 *
Answer:
The slope of a line perpendicular is -1/6
Step-by-step explanation:
Perpendicular lines are opposite reciprocals so you would flip 6/1 to 1/6 and negate it. The answer is -1/6.
Indique la propuesta correcta con respecto a los instrumentos de medida: a) El Voltímetro A.C. Mide valor medio b) El Voltímetro D.C. Mide valor máximo c) El Amperímetro A.C. Mide valor medio d) El Amperímetro A.C. Mide valor eficaz c) El Amperímetro D.C. Se conecta en paralelo
Answer:
Las propuestas correctas son;
a) Voltímetro de CA Mide el valor medio
La magnitud del voltaje de corriente alterna varía periódicamente con el tiempo, dentro de un rango dado
El voltímetro de CA proporciona la lectura y, por lo tanto, mide el valor medio del voltaje, el voltaje pico o el R.M.S. valor de la tensión
b) El voltímetro de CC mide el valor máximo
Los valores de voltaje de un circuito de corriente de CC se fijan con el tiempo y, por lo tanto, el voltímetro de CC mide los voltajes máximos en el circuito.
c) El amperímetro de CA mide el valor medio
Similar a la medición de voltaje de CA, el amperímetro de CA mide el valor de corriente medio
d) El A.C. mide el valor efectivo
La raíz cuadrada media o R.M.S. valor es el valor medido por un R.M.S. Medidor de A.C.
e) El D.C. se conecta en paralelo
Todos los voltímetros se colocan en paralelo con el circuito desde el que se va a medir el voltaje.
Sin embargo, un amperímetro de CC está conectado en serie
Step-by-step explanation:
Based on the data, how many of 650 ice cream eaters would be expected to prefer vanilla or cookie dough ice cream flavor Number of people vanilla 71 strawberry 22 cookie dough 27 chocolate 83
Answer: 305 people
Step-by-step explanation:
The total number of people sampled is:
= 71 + 22 + 27 + 83
= 209
Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:
= 71 + 27
= 98 people
In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:
= 98/ 209 * 650
= 305 people
Ren built a birdhouse with a volume of 224 in.3 Find the height of the birdhouse.
Complete question:
Ren built a birdhouse with a volume of 224 in³ Find the height of the birdhouse. A square pyramid. The square base has side lengths of 8 inches and the height is unknown.
Answer:
the height of the birdhouse is 10.5 in.
Step-by-step explanation:
Given;
volume of the square pyramid, V = 224 in³
length of a side of the square base, a = 8 in
The volume of square pyramid is calculated as;
[tex]V = \frac{a^2h}{3} \\\\where;\\h \ is \ height \ of \ the \ birdhouse \ (Pyramid)\\\\a^2h = 3V\\\\h = \frac{3V}{a^2} \\\\h = \frac{3 \times 224}{8^2} \\\\h = 10.5 \ in[/tex]
Therefore, the height of the birdhouse is 10.5 in.

The cost of an article including 15% for taxes is ghc ghc138. What is the cost of the article without taxes
Answer:
Cost of article before tax is 120.
Step-by-step explanation:
It says cost of an article including 15% tax is 138.
So, let the cost of article without tax as 'x'
So, we can set up equation as
x+15%(x)=138
Simplify it
x+0.15x=138
1.15x=138
Divide both sides by 1.15
x=120
So, cost of article before tax is 120.
Which of the following correctly completes the square for: x^2+2x=48
A. (x+2)^2=52
B. (x+1)^2=49
C. (x+2)^2=47
D. (X-1)^2=26
Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
Answer:
hey I'm pretty sure it's B. (x+2)²=49
Step-by-step explanation:
x²+2x+(2\2)²=48 + (2\2)²
(x+1)²=49

Are the following two expressions equivalent?
Explain how you know...
3(4-x)
6(x+2)-7x
Answer:
no, because the first=12-x
and the second=-1x+2
Step-by-step explanation:
Answer:
No, they are not equivalent.
Step-by-step explanation:
First, we simplify the two expressions.
3(4 - x) = 12 - 3x We multiply everything inside the bracket by 3.
6(x + 2) - 7x = 6x + 12 - 7x = 12 - x Using BODMAS/BIDMAS, we first multiply everything in the brackets by 6 and then simplify.
If we compare 12 - 3x to 12 - x, we can clearly notice that they aren't equivalent. If they were to be equivalent, they would have to be exactly the same values as each other. The 12 is common in both expressions, but the -3x and -x differ, therefore the following two expressions aren't equivalent.

(answer ASAP! thanks.) "As part of a math project, Joel recorded the types of vehicles passing an intersection in one hour. His results are shown on the table below. Explain how you can determine the percent of each type of vehicle. Then calculate the percent of vehicles that are not trucks."
Car: 73
Small truck: 16
Large truck:6
Motorcycle: 2
Bicycle: 3
Step-by-step explanation:
There is a total amount of vehicle of 100
which is good because now you can say 73% is cars 16% is small trucks 6% is large trucks and 2% motorcycle and 3% bicycle. Adding the trucks (small 16, large 6) gives us 24% so you can do 100% - 24% and get 74%. Thanks and goodbye!

calculate the diameter of the circle
Answer:
2.64cm
Step-by-step explanation:
A = π r^2
5.5 = π r^2
1.75 = r^2
r = 1.32
Diameter is then 2(1.32) = 2.64
Answer:
2.65 cm to the nearest hundredth
Step-by-step explanation:
A = πr^2 = 5.5
r^2 = 5.5/ π = 1.5707
r = 1.3231
Diameter = 2 * r
= 2.6462.
