Answer:

a.2:7

b.7:9

c.4:5

hope it helps

Explanation -

a. as original ratio is 10/35 , we reduce it to 2:7.

b. as original ratio is 35/45 , we reduce it to 7:9

c. as original ratio is 40:50 , we reduce it to 4:5

Answer:

55-11=44 and 44-11=33 so 33 it is

Step-by-step explanation:

Well, 5 to 11 is just saying 5:11 just in a different way. This (:) means (to)  also. So how you get the roof to a 33 foot run is to change the 5 into a 3 and the you leave the 11 alone and then you 33 -foot run. Well I really don't really know if that is ther correct anser but if it isn't then read someone's other answer because I don't really know what kind of math this is and I really need to know what grade it is and then I will look it up on the internet. Because some times I get thinmgs wrong if I  don't remember them so I need someone to explain how to do it

Answer:

option C

Step-by-step explanation:

Let ABC be the smallest triangle where

AB = 2cm ; BC = 4cm ; AC = 3cm

ABC = h° ; ACB = g° ; BAC = i °

Let XYZ be the largest triangle where

XY = 4cm ; YZ = 8cm ; XZ = 6cm

XYZ = f ° ; YZX = e°

It's given that ABC & XYZ are similar . So ,

[tex] \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} [/tex]

=> (AB & XY) ; (BC & YZ) ; (AC & XZ) are corresponding sides.

=> (ABC & XYZ) ; (ACB & YZX) ; (BAC & YXZ) are corresponding angles.

Hence,

(h & f) ; (e & g) are corresponding angles

Step-by-step explanation:

Because x is always first in a equation.

Answer:

Replacing x with 3 in 4x-5 tells us f(3) = 7

Step-by-step explanation:

to evaluate f (3), just replace all x  in f(x) = 4x - 5 with 3 :

f(3) =4(3) - 5 = 12 - 5= 7

Answer:

4 units

Step-by-step explanation:

Right now, the line A'B' is 8 units long. Since this was multiplied by 2 to get this number, you can divide it by 2 to get the original number. 8/2 is 4.

Therefore, the correct answer is 4 units!

Step-by-step explanation:

Answer:

480

Step-by-step explanation:

800=100% value

x-60%

800/x = 100%/60%

now solve for x

(800/x)*x=(100/60)*x      ( multiply both sides of the equation by x )

800=1.66666666667*x     ( then we divide both sides of the equation by 1.66666666667 to get x )

480 = x

x= 480

so 60% of 800 is 480

Answer:

y = 5

Step-by-step explanation:

y  = mx + b

5 = 6m + b

5 = 3m + b

Take the first minus twice the second.

-5 = - b

b = 5

Substitute back to calculate m.

5 = 6m + 5

6m = 0

m = 0

Answer:

The correct answer is - Two-paragraph proof.

A paragraph proof is only a two-column proof that is written in sentences. However, since it is easier to leave steps out when writing a paragraph proof.

The solution to the given problem does not need any columns and can be proved in just sentences. Therefore, it is a two-paragraph proof.

Step-by-step explanation:

Answer:

Step-by-step explanation:

there is a 125 degree difference between the two

The difference in temperature from the lowest to the highest is 125°F.

Given that, one year, a certain city experienced a low temperature of -15°F and a high temperature of 110°F.

To find the difference in temperature from the lowest to the highest, we need to subtract the low temperature from the high temperature.

The difference will be in Fahrenheit (F):

Difference = High temperature - Low temperature

Difference = 110°F - (-15°F)

Difference = 110°F + 15°F

Difference = 125°F

So, the difference in temperature from the lowest to the highest is 125°F.

its a because its a resasonable estimate

Answer:

The answer is A no, a reasonable estimate is around 5 × $6 = $30

Step-by-step explanation:

Answer:

38+31+43+x=180

Step 1: Simplify both sides of the equation.

38+31+43+x=180

(x)+(38+31+43)=180(Combine Like Terms)

x+112=180

Step 2: Subtract 112 from both sides.

x+112−112=180−112

x=68

Answer:

The perimeter of the TV = 8 feet

Step-by-step explanation:

The keywords in this question are "similar in shape". This means that the dimensions of the two TVs are equivalent, but they are not the same.

TV in family room = 3 feet wide, 5 feet long = 3/5

TV in bedroom = 1.5 feet wide, x feet long = 1.5/x

Since the TVs are similar:

[tex]\frac{3}{5} = \frac{1.5}{x} \\cross-multiplying:\\3 \times x = 5 \times 1.5\\3x = 7.5\\x = \frac{7.5}{3} \\x = 2.5\ feet[/tex]

Therefore the TV in bedroom is 1.5 feet long and 2.5 feet wide.

Perimeter of a TV = perimeter of a rectangle

Perimeter of a rectangle = (2 × Length) + (2 × width)

Perimeter = ( 2 × 1.5) + ( 2 × 2.5)

= 3 + 5 = 8 feet
