Daniel's goal is to walk 100 miles.• He walks 5 miles every day.• He has
walked for 7 days. Daniel still needs to walk k more miles for his goal.
Which equation could be used to find how many more miles, k, Daniel
will have to walk to meet his goal
Answer:
65 miles
Step-by-step explanation:
Given:
k = how many more miles Daniel has to walkGoal = 100 milesDaily miles = 5 milesNumber of days already walked = 7 daysEquation:
5 × 7 + k = 100
Solving:
⇒ 5 × 7 + k = 100
⇒ 35 + k = 100
⇒ k = 100 - 35
⇒ k = 65

The sum of angle ∠FEC and angle ∠ECF is 90°. Then they are complementary angles.
What is a circle?It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
DE is tangent to circle C, at point F.
Then prove that angle ∠FEC and angle ∠ECF are complementary angles.
We know that the radius of the circle and the tangent on the circle make a right angle at the circumference.
Then angle ∠EFC will be 90°.
The sum of all interior angles of the triangle is 180°. Then we have
∠FEC + ∠ECF + ∠EFC = 180°
∠FEC + ∠ECF + 90° = 180°
∠FEC + ∠ECF = 90°
The sum of angle ∠FEC and angle ∠ECF is 90°. Then they are complementary angles.

20 Points Help Please! Calculate the area of triangle ABC with CD, given A(6,0) B(1,5) C(2,0) D(4,2) with thorough explanation.
The area of the triangle ABC with the coordinates A(6,0) B(1,5) C(2,0) is 10 square units
How to determine the area of the triangle ?The coordinates are given as:
A(6,0) B(1,5) C(2,0) D(4,2)
The area of the triangle is calculated using:
Area = 0.5 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)|
Using the above formula, we have:
Area = 0.5 * |6 * (5 - 0) + 1 * (0 - 0) + 2 * (0 - 5)|
Evaluate the sum of products
Area = 0.5 * |20|
Remove the absolute bracket
Area = 0.5 * 20
Evaluate the product
Area = 10
Hence, the area of the triangle ABC is 10 square units

Colin and Sarah share the rest in the ratio 1:3.
What proportion does Colin get?
Caroline, Colin & Sarah share some money.Caroline will get [tex]\dfrac{2}{3}[/tex] when Caroline, Colin & Sarah share some money.
What is the ratio?The ratio defined as the sharing of the two or three things or it represent that one thing or number is how many times to the other.
One part is excluded in the problem. That part is:
"Caroline gets [tex]\dfrac{1}{9}[/tex] of the money."
If Caroline gets 1/9th, then remaining is:
[tex]1-\dfrac{1}{9}=\dfrac{8}{9}[/tex]
Colin and Sarah share in ratio 3 is to 1, that means 3 + 1 = 4 parts...
8/9th in 4 parts means, each part is:
[tex]\dfrac{\dfrac{8}{9}}{4}=\dfrac{2}{9}[/tex]
We know Colin gets "3" parts of the total, each part is (2/9)th, so 3 parts would be:

An angle that measures 125° is composed of three smaller angles. Two of the smaller angles measure 25° and 40 degrees Tom thinks he can use the equation 25 degrees + (40 degrees - 25 degrees) = s to find the measure of the unknown smaller angle, s. Explain why Tom is incorrect and tell how to find the measure of the third smaller angles
The measure of the other angle is 60°.
What is an Angle ?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
As given in the question
An angle that measures 125° is composed of three smaller angles.
Two of the smaller angles measure 25° and 40 degrees
Tom thinks he can use the equation 25 degrees + (40 degrees - 25 degrees) = s to find the measure of the unknown smaller angle, s
Tom is incorrect because the sum of the smaller angles will be equal to the bigger angle and the equation he has written is wrong.
The right equation and method will be
25 +40+x = 125
x = 125-40-25
x = 60°
Therefore the measure of the other angle is 60°.
