A Paper weight has the shape of a regular triangular pyramid find the surface area of the paperweight put the answer in Square meters
Will Mark brainlest if correct
Answer:
70.75 in²Step-by-step explanation:
area of a triangular pyramid = base area + 3(triangular sides area)
= 1/2 (5) 4.3 + 3 (1/2 x 5 x 8)
= 10.75 + 3(20)
= 70.75 in²

in the figure AB/CD. What are the values of x and y?
A: x=32, y=140
b: x=140, y=52
c: x=52, y=140
d: x=38, y=154
Answer:
C.
Step-by-step explanation:
interior angles for ABCD is 360° and for ABO(triangle above) is 180°
from triangle,
you will get angle for OBA which is 180° - 38° - 90° = 52°
from angle B, we know that, straight line is 180°.
so,
180° = 52° +y- 12°
y = 140°
so, we can calculate x.
360° = 90° + 90° + 128° + x
x = 52°

for a fixed voltage, the current in an electrical circuit varies inversely as the resistance in the circuit. If a certain has a current of 3.5 amps when the resistance is 110 ohms, find the current when the resistance is doubled.
Answer: 1.75 amps
Step-by-step explanation:
V (voltage) = I (current) · R (resistance)
V = 3.5 (110)
= 385
When Resistance is doubled, the current is cut in half.
V = I R
385 = I (2 · 110)
[tex]\dfrac{385}{220}=\text{I}[/tex]
1.75 = I

A car dealership pays $8,350 for a car. They mark up the price by 18% to get the retail price. What is the retail price of the car at this dealership?
Answer:
$9,853
Step-by-step explanation:
18% of $8,350 is $1,503, so if the price increased by 18%, we must add $8,350 and $1,503, which would equal $9,853.

The resistance, R (in ohms), of a wire varies
directly with the length, L (in cm), of the
wire, and inversely with the cross-sectional
area, A (in cm2). A 500 cm piece of wire with
a radius of 0.2 cm has a resistance of 0.025
ohm. Find an equation that relates these
variables.
Answer:
The equation is: [tex]R = \frac{L}{A}[/tex]
Step-by-step explanation:
The resistance, R (in ohms), of a wire varies directly with the length, L (in cm), of the wire, and inversely with the cross-sectional area, A (in cm2).
This means that we want to find an equation for R, which is a fraction.
Since it varies directly with the length L, L is the numerator.
Since it varies inversely with the cross-sectional area, A is the denominator.
So the equation is:
[tex]R = \frac{L}{A}[/tex]
Answer:
R ∝ L/ A
R = K L/ A
0.025= 500K/0.126
the constant, K=6.3 X 10^-6
Step-by-step explanation:
Step 1
The resistance, R (in ohms), of a wire varies directly with the length, L (in cm), of the wire, and inversely with the cross-sectional
area, A (in cm2) is written mathematically as
R ∝ L/ A
Introducing the constant of proportionality,K, we have
R = K L/ A
So given that s 500 cm piece of wire with a radius of 0.2 cm has a resistance of 0.025 ohm.
We would First find area , since radius was given
Area = πr²
= 3.142 x 0.2²= 0.126cm²
Step 2
With our equation , R = K L/ A, puting all the necessary variables, we have
R = K L/ A
0.025= 500K/0.126
Solving for K
0.025= 500K/ 0.126
(0.025 X 0.126)/500 = K
K=6.3 X 10^-6
Which number would divide the numerator and the denominator of the first
fraction to yield the second fraction?
Answer:
2/2
Step-by-step explanation:
Let the numerator and denominator be x/x
10/12÷x/x=5/6
10x/12x=5/6
x/x=5/6÷10/12
x/x=5/6×12/10
x/x=2/2
Therefore the numbers are 2/2
Answer:
2/2
Step-by-step explanation:
To reduce a fraction, you have to divide it by a fraction with the equivalency of 1, since anything else would change the value of the fraction. In this instance, you know that you have the fraction 10/12, and you need to reduce it to 5/6. To do this, you must divide 10/12 by a fraction that equals 1 to create 5/6. Breaking it down, you can know that 10 divided by 2 is 5 and that 12 divided by 2 is 6. 2/2 is equal to 1, so that is the answer.

In the given figure, the area of △ADE is 16 units. What is the area of △ABC?
Answer:
(i) Triangle ABC and triangle ADE are similar triangles. Hence, their ratios will be same.
Ratio of DE to BC is 4:6 => 2:3
To find area, we need to raise the ratio of length to power 2
(2/3)² = 16/x
4/9 = 16/x
x = (16*9)/4
x = 36cm²
Therefore, area of triangle ABC is 36cm²
(ii) Ratio of DE to BC is 4:8 => 1:2
(1/2)² = 25/x
1/4 = 25/x
x = 25*4
x = 100cm²
Therefore, area of triangle ABC is 100cm²

The program manager for an amateur performance night auditioned 12 acts, but there is only room for 3 acts on the program. How many different ways can the program manager arrange 3 different acts from the original 12
Answer:
There are 220 different ways to arrange the acts.
Step-by-step explanation:
The order in which the acts are arranged is not important, so we use the combinations formula to solve this question.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many different ways can the program manager arrange 3 different acts from the original 12
Three acts from a set of 12. So
[tex]C_{12,3} = \frac{12!}{3!(12-9)!} = 220[/tex]
There are 220 different ways to arrange the acts.

Some IQ tests are standardized to a Normal model N(100,19). What is the cutoff value for the top 5% of all IQs
Answer:
The cutoff value for the top 5% of all IQs is 131.255.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 100, \sigma = 19[/tex]
What is the cutoff value for the top 5% of all IQs
This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 100}{19}[/tex]
[tex]X - 100 = 19*1.645[/tex]
[tex]X = 131.255[/tex]
The cutoff value for the top 5% of all IQs is 131.255.
Ahmad wants to practice free-throws. He estimates the distance from the free-throw Line to the hoop and marks it with chalk. Ahmad’s estimate was 13.5 feet. The actual Distance should be 15 feet. Find the percent of error.
Answer: 10%
Step-by-step explanation:
The difference between his estimated and actual distance is 15 - 13.5 = 1.5
The percentage of error is the difference divided by the actual value.
1.5÷15 = 0.10
Converted to a percentage, it is 10%
Answer:
10%
