Answer:

70 degrees

Step-by-step explanation:

uvt = 60 degrees bc 180-120 =60

60+ 50 = 110

180-110 degrees = 70

To Be Honest I Dont Know

I'm just here for the points :P

Answer:

1u--> 5.60

2u--> 11.20

Step-by-step explanation:

3u--> 16.80

1u--> 5.60

2u--> 11.20

£16.80 in the ratio 2 : 1

add both sides of the ratio together to get 3

now divide £16.80 by 3 to get £5.60

now put that £5.60 into

C)36 out of 40

Answer:

Option b,c,d and e are right

Step-by-step explanation:

a ) 18 / 24 x 100 = 75 %

b) 18/ 20 x 100 = 90%

c) 36/ 40 x 100= 90%

d) 54/ 60 x 100 = 90%

e) 81/90 x 100 = 90%

I hope im right!!! ;)

Answer:

The distance between them is 230.65 miles

Step-by-step explanation:

Here we use the Cosine formula

[tex]a^2 = b^2 + c^2 - 2bc\ cos\ A\\\\a^2 = 200^2 + 300^2 - 2\times 200\times 300cos50^{\circ}\\\\= 40,000 + 90,000 - 120,000cos50^{\circ}\\\\= 130,000 - 120,000 \times 0.64\\\\= 130,000 - 76,800\\\\a^2= 53,200\\\\a = \sqrt{53,200} \\\\= 230.65\ miles\ per\ hour[/tex]

Now the distance for one hour is

= 230.65 ÷ 1

= 230.65 miles

Answer:

6/1

Step-by-step explanation:

the reason is because the x is increasing by 1 which is the denominator, and the y is also increasing by 6 which is the numerator. if you were to imagine those lines on a graph you would get a straight line and use rise over run to see that the slop is in fact 6/1

Answer:

he pays 75 dollars for 15 visors

Step-by-step explanation:

Answer:A

Step-by-step explanation:

Interior angles of a triangle ALWAYS have to be equal to 180

The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible

The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides

Answer:160 dollars

Step-by-step explanation: 5x20 is 100 plus 3x20 is 60 which makes 160

Answer:

There's 2.5

Step-by-step explanation:

4 cups is equal to 1 quart

So that means 8 cups is equal to 2 quarts

If we add 2 more cups then we would add 0.5 more quarts.

This means that 10 cups is 2.5 quarts.

Answer:

2.5 quarts

Step-by-step explanation:

since there are 0.25 quarts in one cup. you have to multiply 2.5 by 10. hope this helps*

Do you have PC ?

Answer:

number 2 is c

number 1 is d?

Step-by-step explanation:

because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35  words 35m=w

for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer

Answer:

(For your second question.):

35w=m

Step-by-step explanation:

Why?

It states in the problem itself that miles types 35 words per minute.

"w" stands for words

'm' stands for minutes.

The constant rate relies on the clearest data after all. The equation itself is enough!

Remember: 1 min = 60 seconds.

Answer:

x= -10

Step-by-step explanation:

-3/4 (x+2) =6

multiply by -4/3

(x+2) = -8

Subtract 2

x= -10

Hope that helps!

Answer:

the cube is  bc 6 times 5 is 30 and the triangle is 2 because its the same length as the height

Step-by-step explanation:

Answer:

isoceles but not equilateral

Step-by-step explanation:

it has two sides that are the same length, but not all three sides are the same length

An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal

Answer:

9 years.

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

t = 267.57 / ( 991 × 0.03 ) = 9

t = 9 years

The time required to

accumulate simple interest of $ 267.57

from a principal of $ 991.00

at an interest rate of 3% per year

is 9 years.

Answer:

13.4feet

Step-by-step explanation:

The set up forms a right triangle.

Given

Height of the staircase h = 12 feet

Base of the stairs b = 6feet

Required

Length of the ramp l

Using the pythagoras theorem

l² = h² + b²

l² = 12²+6²

l² = 144 + 36

l² = 180

l = √180

l = 13.42 feet

Hence the length of the ramp to the nearest tenth is 13.4feet

Answer:

x = 26.4

Step-by-step explanation:

Here, we want to get the value of x

To get this, we are to use the appropriate trigonometric ratio

From the question, we have the opposite and the adjacent

The trigonometric ratio to use in this case is the tangent

Mathematically;

Tan 53 = 35/x

x = 35/tan 53

x = 26.37

which is 26.4
