A scale model of an object has a scale of 1 cm : 2 ft. The actual object is 11 feet tall. How tall is the model?
Answer: The model is 69.420 feet tall.
Step-by-step explanation: I asked my teacher.
Answer:
5.5 cm
Step-by-step explanation:
If you take 11 and divide it by 2 you would get 5.5cm. This is the answer because If 1cm is 2 ft you divide it by the actual height and you end up with how tall the model would be.
i need help finding the surface area of a right triangular prism.
Answer:
Surface area of the right triangular prism = 180 m²
Step-by-step explanation:
Surface area of the given right triangular prism = Surface area of triangular sides + Surface area of the rectangular surfaces
Surface area of the triangular sides = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(AB)(AC)[/tex]
By applying Pythagoras theorem in ΔABC,
BC² = AB² + AC²
(13)² = 5² + (AC)²
AC² = 169 - 25
AC = 12 m
Therefore, area of the triangular sides = [tex]\frac{1}{2}(5)(12)[/tex] = 30 m²
Area of the rectangular side with dimensions 5m × 4m,
= 5 × 4
= 20 m²
Area of the rectangular side with dimensions 13m × 4m
= 13 × 4
= 52 m²
Area of the rectangular side with dimensions 12m × 4m
= 12 × 4
= 48 m²
Total surface area of the prism = 2(30) + 20 + 52 + 48
= 180 m²

Answer:
For the part that contains organic matter your answer is, 35 negative result
For the part that does not contain organic matter your answer is, 60 positive result
Step-by-step explanation:
If we pay attention to the part that contains organic matter the total amount 700 and 665 is positive, so subtract them 700-665 to get 35 negative result
For the part that does not contain organic matter the total amount is 300, and 240 of it is negative, so subtract 240 from 300 to get 60 positive result

HEY HELP WAYYY OVERDUE NEED IN 10 MINS PLEASE ANSWER CHOICES ARE : 29.76 91.5 180 188.93 223.07
Answer:
I need use this 29.76 91.5 180 188.93 223.07 for what? Can you explain me what I need to do? please O_O
Step-by-step explanation:
Answer:
223.07
Step-by-step explanation:
Hey There!
So the first step of this problem is to find the equation for the area of a parallelogram and the area of a circle
The area of a parallelogram is equal to bh
[tex]base x height[/tex]
the base is 20 and the height is 15
20x15=300
Now we want to find the equation for area of a circle
to find the area of the circle we use the formula [tex]A = pi xr^{2}[/tex]
A = π x radius²
the radius is the diameter divide by 2
14/2=7 so the radius is 7
now we just plug 7 into the area of a circle formula
7²=49
49x3.14=153.86
But because it is a semi circle we divide by 2
153.86/2=76.93
Now to find the area of the object we subtract 76.93 from 300
300-76.93=223.07
Therefore the area of that object is 223.07

Answer:

Step-by-step explanation:
Hi
A market research analyst claims that 32% of the people who visit the mall actually make a purchase. You think that less than 32% buy something and decide to test the claim. You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase. The value of the test statistic is about:
A. 1.74
B. 1.60
C. 1.48
D. -1.60
E. -1.48
Answer:
E. -1.48
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A market research analyst claims that 32% of the people who visit the mall actually make a purchase.
This means that:
[tex]\mu = 0.32[/tex]
[tex]\sigma = \sqrt{0.32*0.68} = 0.4665[/tex]
You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase.
This means that [tex]n = 82, X = \frac{20}{82} = 0.2439[/tex]
The value of the test statistic is about:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.2439 - 0.32}{\frac{0.4665}{\sqrt{82}}}[/tex]
[tex]t = -1.48[/tex]
So the correct answer is given by option E.

Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Let x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiply both sides by 100.
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Divide both sides by 50.
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
The amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Therefore, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

WILL GIVE BRAINLIEST!!
If l is parallel to m, find the value of x
Answer:
x=24
Step-by-step explanation:
2x+13+3x+47=180
we know that this is true because m is a line so 47 and 3x make up part of a 180 degree angle. The last part is 2x+13 because of corresponding angles are equal with parallel lines
we can simplify this like this
5x+60=180
5x=120
x=24

yeah that other guy is right, give him brainiliest
