if there are 300 calories in 100 g of a certain food, how many calories are there in a 30 g portion of food​

Answer:

y = 25

Step-by-step explanation:

Substitute x = 5 into the equation for value of y

y = 3(5) + 10 = 15 + 10 = 25

Answer:

x=2

Step-by-step explanation:

Since the are the same equation they are already equal

Answer:

x=2

Step-by-step explanation:

Answer:

A. is not true

Step-by-step explanation:

[tex]\angle{BCA}[/tex] appears to be acute, and [tex]\angle{BCD}[/tex] appears to be its obtuse supplement.

Just to be sure the diagram isn't lying to you, set this up:

4x + 9 + (9x - 11) = 180

13x - 2 = 180

13x = 182

x = 14

[tex]m\angle{BCA}=65^\circ\\m\angle{BCD}=115^\circ[/tex]

Those two angles are not congruent.

Answer:

$250

Step-by-step explanation:

To find the total multiply 6.25 and 40 together

6.25x40

$250 (Don't forget the dollar sign)

Answer:

250

Step-by-step explanation:

If she work 40 hours and earns $6.25 per hour for 40 hours you multiply howmuch she makes by the amunt of time she worked, so 6.25x40 = 250

Answer:

25 squared cm

Step-by-step explanation:

Use the formula A = [tex]\frac{1}{2}[/tex]h ([tex]b_{1} + b_{2}[/tex])

h = height

[tex]b_{1}[/tex] = base 1

[tex]b_{2}[/tex] = base 2

A = [tex]\frac{1}{2}[/tex] (5) (7.2 + 2.8)

A = 25

answer:

x = 3

y = 6

step-by-step explanation:

y = 2x

3x - y = 3

3x - 2x = 3

3x - 2x = 3

x = 3

y = 2x

y = 2(3)

y = 6

To find the volume multiply all 3 numbers together.

2 1/2 x 1 1/2 = 3 3/4

3 3/4 x 3 = 11 1/4

The volume is 11 and 1/4 cubic units

Answer:

a= 4,3

b=1,2

c=-3,4

d=-1,2

e= -2,-1

f= -4,-3

g=1,-2

h=4,-1

k=-3,0

Answer:

The middle one because there is only 1 value of y for every value of x.

Answer:

416 cm^2

Step-by-step explanation:

The formula for the area of a trapezoid is:

[tex]\frac{(b1+b2)*h}{2}[/tex]

where b1 and b2 are the bases and h is the height. We can plug what we have into the formula:

[tex]\frac{(14 + 38)*16}{2}[/tex]

[tex]\frac{(52)*16}{2}[/tex]

[tex]52*8[/tex]

416 cm^2

Answer:

x = 0 , y = 8

Step-by-step explanation:

x = y - 8 -----(1)

7x + 2y = 16 --------(2)

Substitute (1) in (2)

7(y - 8) + 2y = 16

7y - 56 + 2y = 16

9y = 72

y = 8

Substitute y in (1)

x = 8 - 8 = 0

Step-by-step explanation:

738.00 - 78.00 =  660

Am subtracting because he made a down payment so I can get  the remaining of the money.

Let x = # of months

You use the remaining of the money to divide by 30 because of his monthly payments.

660 / 30x =

x = 22

Divide by 30 to isolate the variable x.

Answer:

Harry receives £4500

Step-by-step explanation:

Sum of the ratio = 8

Total amount - 7200

[tex]Jay's\ share = \frac{1}{8} \times 7200 = 900\\\\Sheila's \ share = \frac{2}{8} \times 7200 = 2 \times 900 = 1800\\\\Harry 's \ share = \frac{5}{8} \times 7200 = 5 \times 900 = 4500[/tex]

Answer:

I'm pretty sure your answer is 3, -4

Step-by-step explanation:

Answer:

Step-by-step explanation:

3*3+2/3-2*6+5/6

=9+2/3-12+5/6

=11/3-17/6

take lcm of the denominator

=11*2-17*1/6

=22-17/6

=5/6

Answer:

5/6

Step-by-step explanation:

3 2/3 - 2 5/6

= 3 4/6- 2 5/6

=5/6

you just find the surface area for each rectangle/square and then add them together

5x8=40

5x8=40

25x5=125

8x25=200

5x25=125

8x25=200

add those numbers and you get 730 :)

Answer:

Step-by-step explanation:

cos theta is 5/13

so, adjacent=5 ,hypotenuse=13 and opposite=?

hypotenuse^2=adjacent^2+opposite^2

13^2=5^2+opposite^2

169-25=opposite^2

[tex]\sqrt{144}[/tex]=opposite

12=opposite

sin theta=opposite/hypotenuse

=12/13

The first Image is the first part of the question, to write the correct order of letter to the finish line, we will use the details on the first image.

Hence the Correct order of letter to the Finish line: AEIJKGFCH

Answer:

49degrees

Step-by-step explanation:

The sum of angle on a straight line is 180degrees, hence;

x + y + z = 180

x + 45 + 86 = 180

x + 131 = 180

x = 180 - 131

x = 49degrees

Hence the value of x is 49degrees

Answer:

Step-by-step explanation:

Given

The function is not clear, so I will use:

[tex]x(t) = 2+ 3t + t^2[/tex]

Required

Speed over 2 to 10s

This is calculated as:

[tex]Speed = \frac{x(a) - x(b)}{a - b}[/tex]

Where

[tex](a,b) =(2,10)[/tex]

So, we have:

[tex]Speed = \frac{x(2) - x(10)}{2 - 10}[/tex]

[tex]Speed = \frac{x(2) - x(10)}{-8}[/tex]

Calculate x(2) and x(10)

[tex]x(2) = 2+ 3*2 + 2^2 =12[/tex]

[tex]x(10) = 2+ 3*10 + 10^2 =132[/tex]

So, we have:

[tex]Speed = \frac{12 - 132}{-8}[/tex]

[tex]Speed = \frac{-120}{-8}[/tex]

[tex]Speed = 15[/tex]

Answer:

25

Step-by-step explanation:

Answer:

x = 5

y = 6

Step-by-step explanation:

Let's Solve for x-value first:

By the midsegment theorem we can say;

18 = 2x + 8

18 - 8 = 2x

10 = 2x

10/2 = x

5 = x

Now that we have x-value, let's figure out y-value similarly;

22 = 4y - 2

22 + 2 = 4y

24/4 = y

6 = y

There is the answer!

x = 5, and

y = 6

Answer:

8211 miles

Step-by-step explanation:

Delia flew 2416 miles on the first year of the job

She flew 3719 miles on the second year of the job

She flew 2076 miles more than the first and second year combined on the third year

= 2416+3719

= 6135

= 6135+2076

= 8211

Hence Delia flew 8211 miles on the third year
