what is the length of AC

9514 1404 393

Answer:

  62°

Step-by-step explanation:

The measure of the external angle where the secants meet is half the difference of the arcs they subtend.

  ∠A = (DE - BC)/2

  2×∠A = DE -BC

  DE = BC + 2×∠A

  DE = 38° +2(12°)

  arc DE = 62°

Answer:

7.5

Step-by-step explanation:

First, turn 25% into a decimal. You do this by dividing 25 by 100.

25/100 = 0.25

Now, multiply 0.25 by 30.

30 x 0.25 = 7.5

Answer:

A. Commutative Property of Addition

Step-by-step explanation:

Given equation,

9 + 8 = 8 + 9

If a and b are any real numbers,

By the commutative Property of Addition

a + b = b + a

By the identity Property of Addition

a + 0 = a

By the distributive Property,

a(b+c) = ab + ac

By the associative property of addition,

a + (b + c ) = (a + b) + c

Hence, OPTION A is correct.

Answer:

Commutative Property of Addition

Step-by-step explanation:

I assume you mean 9+8=8+9

In that case it is the Commutative Property of Addition.

That means you can switch the numbers around and it will stay the same value.

Answer:

uhhh yeah it is

Step-by-step explanation:

Answer:

yes it is

Step-by-step explanation:

all you do is 1 times 2 = 2 and 4 times 2= 8 they are equivalent

Answer:

Yes

Step-by-step explanation:

1 is 4.50

4.50*2=9

4.50+4.50

(4+4) + (0.50+0.50)

4.50*4=18.00

4.50+4.50+4.50+4.50

(4+4+4+4) + (0.50+0.50+0.50+0.50)

4.50*7= 31.50

4.50+4.50+4.50+4.50+4.50+4.50+4.50 0.50

(4+4+4+4+4+4+4) + (0.50+0.50+0.50+0.50+0.50+0.50+0.50)

Answer:

1.75

Step-by-step explanation:

Since the curtains are going up in .25. We need to add .25 to 1.5.

1.5 + .25 = 1.75

The length of curtains will Riya buy is 1.75 m.

A sequence is an arrangement of numbers in a specific order. A series, on the other hand, is defined as the sum of the elements in a sequence.

For example,  In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.

We have length of curtains as

1m, 1.25 m, 1.5 m,...

Now, from above the first term is 1.

Common difference, d= 1.25 - 1 = 0.25

So, the next length of curtain will be

= 1 + (4-1)0.25

= 1 + 0.75

= 1.75 m

Answer:

8 2/5 bags of rice

Step-by-step explanation:

The above question is solved as;

5/8 pounds of rice = 1 bag of rice

5 1/4 pounds of rice = x bags of rice

Cross Multiply

5/8 pounds × x bags of rice = 5 1/4 pounds of rice × 1 bag of rice

x bags of rice = 5 1/4 pounds of rice × 1 bag of rice/ 5/8 pounds

x bags of rice = 5 1/4 ÷ 5/8

x bags of rice = 21/4 ÷ 5/8

x bags of rice = 21/4 × 8/5

x bags of rice = 42/5

x bags of rice = 8 2/5 bags of rice

Therefore, malcolm can fill 8 2/5 bags of rice.

Step-by-step explanation:

☆Since since we're given the slope, all we need to do is find the y-intercept.

☆The slope-intercept formula is: y = mx + b.

☆We are going to plug in according to the formula.

[tex]y = mx + b \\ \\ 10 = \frac{1}{2} ( - 6) + b \\ 10 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: \: \: \: \: }{13 = b \: \: \: \: \: \: \: \: \: \: \: } [/tex]

Answer:

Multiply the bottom equation by -3/2 then add the equations.

Multiply the top equation by-3. then add the equations

Step-by-step explanation:

Given the simultaneous equation

2x- 6y=6  ... 1

6x - 4y = 2 ... 2

To eliminate a variable, we have to make the coefficient of one of the variable to be the same.

Multiply equastion 1 by -3

-6x+18y= -18  

6x - 4y = 2

Add the result:

-6x + 6x + 18y-4y = -18+2

18y-4y = -18+2

14y = -18

y = -9/7

Another way is to Multiply the bottom equation by -3/2 then add the equations.

Multiplying equation 2 by -3/2 will give;

6x(-3/2) - 4y(-3/2) = 2(-3/2)

-9x + 6y = -3

Add to equation 1;

2x- 6y=6

-9x + 2x + 0 = -3+6

-7x = 3

x = -3/7

Hence the correct two options are;

Multiply the bottom equation by -3/2 then add the equations.

Multiply the top equation by-3. then add the equations
