Answer:

184960

Step-by-step explanation:

1445 x 128 = 184960

Answer:

3

Step-by-step explanation:

A ( 2, 2 )

( x1, y1 ) = ( 2, 2 )

Here,

x1 = y1 = 2

B ( - 2, - 2 )

( x2, y2 ) = ( - 2, - 2 )

Here,

x2 = y2 = - 2

Distance formula : -

d = √ ( x2 - x1 )² + ( y2 - y1 )²

AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²

= √ ( - 2 )² + ( - 2 )²

= √ 4 + 4

AB = √8

The value of √8 is 2.828.

Roundoff to nearest 10 is 3.

Answer:

she well have $16

Step-by-step explanation:

so 12-8 =4 and she sells them for$ 4 each so 4X4 is 16 so $16

Answer:

-3y=-24

Step-by-step explanation:-10 and 10 cancel, then go form there -8y +5y is -3y then add -14 and -10 you get -24 so your final answer is -3y=-24

Answer:

5.3 of both lengths, if the lengths are the same

Step-by-step explanation:

28 squared equals 5.29... which rounds up to 5.3 if you're trying to find a number rounded up to the tenths. I also tried with 5.2 and 5.4, but they weren't in btw. 28 and 29, so the answer must be 5.3

Answer:

a) 251.33 cm

b) 40 times

Step-by-step explanation:

C = d x r

a) C = 80 cm x 3.14 = 251.33 cm

b) 100 m = 10,000 cm

10,000cm/251.33cm = 40 times

Answer:

48windows

Step-by-step explanation:

we know that the whole building contains 864 windows and the building have 18 floors so divide the 864 windows by 18 floors to get 48windows per each floor

Answer:

f(3) = 16 and f(4) = 23

Step-by-step explanation:

Finding f(3) simply means we're finding the value of the function when x = 3, so we can plug 3 in for x in our function:

f(3) [tex]3^{2} +7[/tex]

[tex]3^2 = 9[/tex], so now we have:

f(3) = 9 + 7

9 + 7 = 16, so f(3) = 16.

Now we want to find the value of x that makes the function equal 23, so let's set our function equal to 23:

[tex]23 = x^2 + 7[/tex]

We want to get x by itself in order to find the value, so let's start by subtracting 7 from both sides:

23 - 7 = [tex]x^2[/tex]

23 - 7 = 16, so 16 = [tex]x^2[/tex]

Now, we can take the square root of both sides:

[tex]\sqrt{16} = \sqrt{x^2} \\\sqrt{16} = 4\\\sqrt{x^2} = x[/tex], so now we have:

4 = x

Answer:

single egg

Step-by-step explanation:

0.20 x 12 = 2.40

regular = 2.50

Answer:

one egg a time

Step-by-step explanation:

We know a dozen eggs consists of 6eggs and in total it costs $2.50

Now 1 egg is $0.20 when you buy 5 more eggs separately it gives you a total amount of $1.25 so you save more money when you buy one egg at a time

Answer:

132 minutes

Step-by-step explanation:

If you see that 1 mile is 22 minutes, then you would know 2 miles is double, three miles is triple and so on. So you would do 22x6 for the six miles to get your answer of 132, or you can even do 22 plus 22 six times.

Answer:

132 minutes = 2 hours and 12 minutes

Step-by-step explanation:

22 x 6 = 132 (minutes)

to find it in hours:

132 divided by 60 = 2.2 (2 hours)

2 x 60 = 120

132 - 120 = 12 (minutes)

Answer:

The form for a point-slope equation is y-y1=m(x-x1), where ”m” is the slope and (x1,y1) is a point on the graph. Substituting in the slope and point, the equation is y+7=-4(x-2).

Answer:

27.7 degrees

Step-by-step explanation:

We can use the inverse sine to find the angle x as we are given the opposite sided length and the hypotenuse

x = sin-1(13/28)

x = 27.66

x = 27.7 (round to tenths)

Answer:   Since 6 is six units away towards right from 0, the absolute value of 6 is just 6.  HOPE THIS HELPS!!!!   :)

Answer:

6

Step-by-step explanation:

The absolute value of 6 is just 6 because the absolute value of a number is just the positive version of it even if it is already a positive.

Step-by-step explanation:

2(7x +8)=12

2(7x +8)/2 =12/2

7x +8 =6

7x=6-8

7x = -2

x= -2/7

Hi there! :)

12=2(7x+8)

Use the Distributive property:

12=14x+16

Move all the numbers to the right side and the variables to the left side:

-14x=16-12

-14x=4

Divide both sides by -14 to isolate x:

x=[tex]-\frac{4}{14} \\-\frac{2}{7}[/tex]

Hope this helps you!

Answer:

x = [tex]\frac{3b-2d}{a-5c}[/tex]

Step-by-step explanation:

ax + 2d = 5cx + 3b ( subtract 5cx from both sides )

ax - 5cx + 2d = 3b ( subtract 2d from both sides )

ax - 5cx = 3b - 2d ← factor out x from each term on the left side

x(a - 5c) = 3b - 2d ← divide both sides by (a - 5c)

x = [tex]\frac{3b-2d}{a-5c}[/tex]

Answer:

2-7/ 5-3

Step-by-step explanation:

(3,7) (5,2)

2-7/ 5-3

The slope of the line contains the given points. C(1, –7), D(5, 13) is 5 after using the slope formula.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have given two points:

C(1, –7) and D(5, 13)

The slope can be found using the slope formula:

[tex]\rm m =\dfrac{13+7}{5-1}[/tex]

m = 20/4

m = 5

Thus, the slope of the line contains the given points. C(1, –7), D(5, 13) is 5 after using the slope formula.

Multiply a number to both the numerator and the denominator: 0.35 × [tex]\frac{100}{100}[/tex]

Write as a single fraction: [tex]\frac{0.35*100}{100}[/tex]

Calculate the product or quotient: [tex]\frac{35}{100}[/tex]

Rewrite a fraction with denominator equals 100 to a percentage: 35%

Answer: 35%

Answer:

Answer:

the number of students in each van : 14

Step-by-step explanation:

a = how many students fit into a van

b = how many students fit into a bus

School A: 4a+7b=448 (1)

School B: 9a+14b=910 (2)

(1) => b = (448-4a)/7

subs to (2) => 9a+ 2(448-4a) = 910

=> a = 14

=> b =56

Answer:

4/2 <3

Step-by-step explanation:

Step-by-step explanation:

2 ft / 1 second

and now

x/10 foot / 1/4 second

we need to multiply the original ratio by 1/4 to get the same denominator :

2/1 × (1/4)/(1/4) = (2/4) / (1/4) = (1/2) / (1/4)

how many 10th foot are 1/2 ?

we need to bring 1/2 to the denominator of 10.

1/2 = x/10

10 = 2x

x = 5

so, 1/2 = 5/10

therefore, or answer is

5/10 foot / 1/4 second

Answer:

2000 workers

Step-by-step explanation:

60%= x

40% = 800 (the ones that arent men)

(800÷2= 400) which means..

40%÷2=400

20%=400 so

40% + 20% = 60%

800 + 400 = 1200

now that

60%=1200 workers add the 40percent of workers to the 60% of workers which is (40%=800)

=2000 workers in total
