Calculate the length of line AB
?????? Cos ?? I don’t know the difference between cos and tan fully yet , but ASAP help here
The answer is M
Step-by-step explanation:
Cosine: this is the length of the side right next to the angle divided by the longest side/ hypotenuse.
Tan: this is the length of the side opposite of the angle divided by the side directly adjacent/ next to the angle.
In this case, cosine would be 6/10 which Is also 3/5. the angle right next to 6 is Angle M

Step-by-step explanation:
The water content of a certain fruit, by weight, is 80%. Therefore, 20% of the
fruit, by weight, is other material.
When left in the sun to dry, the fruit loses 75% of its water content, and the
amount of other material remains the same.
What percent of the dried fruit is water?
Your solution includes the percent water in the dried fruit and an explanation that supports your answer. in other words, how did you find that percent value?
Answer:
50% is water
Step-by-step explanation:
1. 80% is water and 20% is from other material
2. Lets say a fruit has 100g, to make it easier to understand
2. if the fruit loses 75% of its water, it will lose 75% of 80%, which is 60% of the total weight or 60g lost. The fruit is now 40g
3. If 20% was other material (20g), now other material is 50% (the same 20g)
4. Water is now only 20g, which is 50% of the total weight
Answer:
50% is water I think I am really sorry I I is wrong

What should replace a, b, and x in B(t) = abx for the amount of money in the account, B(t), after t months with an initial deposit of $100.
Answer:
[tex]B(t) =100 * (1 + r)^t[/tex]
Step-by-step explanation:
Given
[tex]B(t) = ab^x[/tex]
[tex]x = t[/tex] ---- months
[tex]a = 100[/tex] --- Initial deposit
Required
Replace a, b and x
Substitute: [tex]a = 100[/tex] in [tex]B(t) = ab^x[/tex]
[tex]B(t) = 100 * b^x[/tex]
Substitute:[tex]x = t[/tex]
[tex]B(t) = 100 * b^t[/tex]
From the question, the rate, r is not given.
And
[tex]b = 1 + r[/tex]
So, the expression becomes:
[tex]B(t) =100 * (1 + r)^t[/tex]
What is the height of the pyramid?
Answer:
4
Step-by-step explanation:
The slant height of the pyramid is marked as 5. If we drew and auxiliary 2D right triangle in the pyramid, this slant height would be the hypotenuse and one of the legs would be the height of the pyramid. The base leg would be equal to half of a side of the pyramid (3). Therefore, we can use the Pythagorean theorem to find the height ([tex]h[/tex]):
[tex]3^2+h^2=5^2,\\h^2=16,\\h=\boxed{4}[/tex]
John is putting a fence around his garden that is shaped like a half circle and a rectangle.How much fencing will John need? Use for .32 ft39 ft46 ft57 ft
Answer:
The perimeter of the garden = 46 ft
Step-by-step explanation:
The exact question is as follows :
Given - John is putting a fence around his garden that is shaped like a half circle and a rectangle.
A rectangle has a length of 14 feet and width of 7 feet. A semicircle with diameter of 7 feet is on top of the rectangle.
To find - How much fencing will John need? Use 22 over 7 for Pi.
A. 32 ft
B. 39 ft
C. 46 ft
D. 57 ft
Solution -
The figure is as follows :
The perimeter of the garden is equal to sum three sides of the rectangle plus the circumference of a semicircle
Now,
Given that,
Length of Rectangle = 14 feet
Breadth of Rectangle = 7 feet
Now,
Sum of three sides of Rectangle = 14 + 14 + 7
= 35
Now,
Circumference of Semicircle = (1/2)[tex]\pi[/tex] D where D is the diameter
So,
Circumference of Semicircle = (1/2)(22/7)(7)
= 11
⇒Circumference of Semicircle = 11
So,
The perimeter of the garden = 35 + 11
= 46 ft
⇒The perimeter of the garden = 46 ft

What value of x can make 4x-10=18 true?
Answer:
Im pretty sure 7
Step-by-step explanation:
4×7=28 28-10=18
Answer:
7
Step-by-step explanation:
[tex]4(7) - 10 = 18 \\ 28 - 10 = 18 \\ 18 = 18[/tex]
Pls solve I will give the barinliest answer plssss
well we know the line will be equal to 180 degrees so we will have an equation like this
x+100+3x=120
we subtract 100 from 180 to get 80.
180-100=80
however x cannot be 80 bc we still have the 3x.
when you do the math, you will see that 20 times 3 is 60.
20×3=60
going even further we see that 60 plus 20 is 80
60+20=80
so to check our work, lets solve this equation
20+100+3×20=180
20+100=120
3×20=60
120+60=180
so your answer is x=20

Find the value of x
Answer:
x = 12
Step-by-step explanation:
Both angles have the same measurement, therefor you can set your formula up as
9x + 1 = 11x-23
9x + 1 + 23 = 11x
24 = 2x
24/2 = x
12 = x
