Brett has consumed 1,400 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily

calorie total to 2,000 calories per day. How many calories does he have left to consume for the day? Is 1,200 a viable solution to this problem?
I NEEED HELPP PLZZ :(
A Yes; 1,200 is less than 1,400.
B Yes; 1,200 is less than 2,000.
C No; 1,200 is more than the 400 he burned off at the gym.
D No; 1,200 will cause him to exceed 2,000.

Answer

D

Step-by-step explanation:

D is correct because 1,400-400= 1,000

so he can only consume 1,000 more calories so 1,200 will cause him to go over 2,000

Points a, b, and c are midpoints of the sides of right triangle def. Which statements are true select three options. A B C D E

bagirrra123 [75]

Answer : The correct statements are,

AC = 5 cm

BA = 4 cm

The perimeter of triangle ABC is 12 cm.

Step-by-step explanation :

As we know that a, b, and c are midpoints of the sides of right triangle that means midpoint divide the side in equal parts.

Now we have to calculate the sides of triangle ABC by using Pythagoras theorem.

Using Pythagoras theorem in ΔACF :

$(AC)^2=(FA)^2+(CF)^2$

Now put all the values in the above expression, we get the value of side AC.

$(AC)^2=(3)^2+(4)^2$

$AC=\sqrt{(9)^2+(16)^2}$

$AC=5cm$

Using Pythagoras theorem in ΔDAB :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(BD)^2=(AD)^2+(BA)^2$

Now put all the values in the above expression, we get the value of side BA.

$(5)^2=(3)^2+(BA)^2$

$BA=\sqrt{(5)^2-(3)^2}$

$BA=4cm$

Using Pythagoras theorem in ΔBEC :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(BE)^2=(CE)^2+(CB)^2$

Now put all the values in the above expression, we get the value of side CB.

$(5)^2=(4)^2+(CB)^2$

$CB=\sqrt{(5)^2-(4)^2}$

$CB=3cm$

Now we have to calculate the perimeter of ΔABC.

Perimeter of ΔABC = Side AB + Side CB+ Side AC

Perimeter of ΔABC = 4 + 3 + 5

Perimeter of ΔABC = 12 cm

Now we have to calculate the area of ΔABC.

Area of ΔABC = $\frac{1}{2}\times 4\times 3=6cm^2$

Now we have to calculate the area of ΔDEF.

Area of ΔDEF = $\frac{1}{2}\times 8\times 6=24cm^2$

Area of ΔABC = $\frac{6}{24}\times$ Area of ΔDEF

Area of ΔABC = $\frac{1}{4}$ Area of ΔDEF

Which statements accurately describe the function f(x) = 3(StartRoot 18 EndRoot) Superscript x? Select three options. The domain

Studentka2010 [4]

Answer:

The domain is all real numbers.

The initial value is 3

The simplified base is $9\sqrt{2}$

Step-by-step explanation:

The given function is $f(x)=3(\sqrt{18})^x$ .

To find the initial value, we put x=0 into the function:

$f(0)=3(\sqrt{18})^0$ .

$f(0)=3(1)=3$ .

The initial value is actually 3.

The given function is an exponential function, therefore the domain is all real numbers.

The range of this function refers to all values of y for which the function is defined.

The line y=0, is the horizontal asymptote.

The range is $y\:>\:0$

The simplified base is $3\sqrt{18}=3\sqrt{9\times2}$ .

$3\sqrt{18}=3\sqrt{9}\times\sqrt{2}$

$3\sqrt{18}=3\times3\times\sqrt{2}$

$3\sqrt{18}=9\sqrt{2}$

A 6 foot long board is propped against the wall of a house. The board forms a 60 degree angle with the ground. How far is the ba

Zarrin [17]

To solve this problem you must apply the proccedure shown below:
1. You have that the lenght ot the board is 6 feet and <span> forms a 60 degree angle with the ground. Therefore, you have:
Sin</span>α=opposite/hypotenuse
α=60°
opposite=x
hypotenuse=6
2. When you substitute the values, you obtain:
Sin(60°)=x/6
3. Now, you must solve for x, as following:
x=6Sin(60°)
x=5.19
Therefore, the answer is: 5.19 feet.

Which action will solve the equation?. m + 20 = 9. . Add 9 to each side.. Subtract 9 from each side.. Add 20 to each side.. Subt

Kruka [31]

M + 20 = 9
u need to subtract 20 from both sides because u want to isolate m

m + 20 = 9
m + 20 - 20 = 9 - 20
m = - 11
