Answer:

BC = 6

Step-by-step explanation:

Look at two corresponding sides that have both lengths given.

They are AB = 4 and XY = 3.

We need BC, and its corresponding side YZ = 4.5.

We can use a proportion.

BC/YZ = AB/XY

a/4.5 = 4/3

3a = 4.5 * 4

a = 1.5 * 4

a = 6

Answer: BC = 6

Answer:

Try 1.09

Plz let me know if this is right if not I am sorry I tried.

Answer:

Larissa was more successful

Step-by-step explanation:

Ellen: 2/4 = 1/2

Larissa: 12/16 = 3/4

3/4 > 1/2

Larissa was more successful.

Answer:

Step-by-step explanation:

2/4 = 1/2

12/16 = 3/4

So Larissa was the most successful.

Answer:

see explanation

Step-by-step explanation:

Using the identities

tan x = [tex]\frac{sinx}{cosx}[/tex] , sec x = [tex]\frac{1}{cosx}[/tex] , csc x = [tex]\frac{1}{sinx}[/tex] , then consider left side

sinxcosxtanxsecxcscx

= sinxcosx × [tex]\frac{sinx}{cosx}[/tex] × secxcscx ← cancel cosx on numerator/ denominator

= sinx × sinx × [tex]\frac{1}{cosx}[/tex] × [tex]\frac{1}{sinx}[/tex] ← cancel sinx on numerator/ denominator

= sinx × [tex]\frac{1}{cosx}[/tex]

= [tex]\frac{sinx}{cosx}[/tex]

= tan x

= right side , thus proven

Answer:

Step-by-step explanation:

first subtract 125-180=X you will get   X=55 so then add  X+X+y=180 which x+x+y= is actually  55+55+y=180 but don't add the y just yet add 55+55 then you will get 110+y=180 so then flip it backwards and do y=180-110 and your anwser is  y=70

Answer:

A

Step-by-step explanation:

I = Prt = r * Pt

divide Pt from both side we get

I/(Pt) = r

Answer:

a

Step-by-step explanation:

I = Prt ( isolate r by dividing both sides by Pt )

[tex]\frac{I}{Pt}[/tex] = r , that is

r = [tex]\frac{I}{Pt}[/tex] → a

Answer:

G(t) = -9t - 4

g( ) = 23

Step-by-step explanation:

G(t) which = -9t then u - 4 g( ) from 9t which also equals 23

I hope this helps!

Answer:

6 Inches

Step-by-step explanation:

A yard is 3 feet (36 inches).

Answer:

Slope: - 3/4

Step-by-step explanation:

Place your pencil on point y= 4. Go up 3 spaces, then, 4 to the left to the next point.

Slope = - 3/4

( a line going up hill: positive slope. A line going downhill: negative slope)

Answer:

interest earned is $176

Step-by-step explanation:

Interest = Principal x Rate x Time

I = 880 x .04 x 5

I = 176

Answer:

$176

Step-by-step explanation:

Simple interest  = P ( initial money )*r (rate ) *t ( time )

P = $880

r = 4% = 0.04

t = 5 years

Simple interest  = 880 * 0.04 * 5 = $ 176

Interest you earn in 5 years is $176.

Answer:

The answer is A, because this expression translates to the number of students on the 6th floor being greater than (due to the < symbol) the number of students of the 1st and 2nd floor combined (due to the + symbol).

Step-by-step explanation:

Answer:

(0.5, 1 )

Step-by-step explanation:

y = 4x - 1 → (1)

2x + 2y = 3 → (2)

Substitute y = 4x - 1 into (2)

2x + 2(4x - 1) = 3 ← distribute parenthesis and simplify left side

2x + 8x - 2 = 3

10x - 2 = 3 ( add 2 to both sides )

10x = 5 ( divide both sides by 10 )

x = [tex]\frac{5}{10}[/tex] = 0.5

Substitute x = 0.5 into (1)

y = 4(0.5) - 1 = 2 - 1 = 1

solution is (0.5, 1 )

Slope, in the form of y = mx + b, is m

[1] 9

    () It is the m

[2] -1/2

    () It is the m

[3] 2

    () add 2x to both sides

[4] 3/4

    () add 4y and subtract 12 from both sides (4y = 3x - 12) and then divide by 4

Have a nice day!

Step-by-step explanation

When subtraction two negatives it becomes it bigger negative, so basically your adding to two numbers but its actually making a bigger negative.

Answer:

Step-by-step explanation:

-330 - 811 = - 1,141

Answer:

-26

Step-by-step explanation:

Dropping here means subtracting. That means that we calculate:

-10 - 16 = -26

Answer:

21

Step-by-step explanation:

Simplify the ratio 6 : 10

The simplified ratio is 3 : 5.

The ratio is 3:5 now we have to figure out what the ration of 35 is so lets sovle that. Since

3 : 5 = X : 35

Then we know

3/5 = X/35

Multiplying both sides by 35 cancels on the right

35 × (3/5) = (X/35) × 35

35 × (3/5) = X

Then solving for X

X = 35 × (3/5)

X = 21

Therefore

3 : 5 = 21 : 35
