Answer:

DEC+DEF=180

DEC=180-116

DEC=64°

in triangle DCE

angle D+angle C+angle E=180

7y+6+4y+64=180

11y+70=180

11y=180-70

11y=110

y=110/11

y=10°

angle C=4y

=4(10)

=40°

A cookie contains 9 grams of fat. If you eat no fewer than 4 and no more than 7 cookies, how many grams of fat will you
Hitman42 [59]

Step-by-step explanation:

Since each cookie has 9 grams of fat, four cookies would contain 4*9 = 36 grams of fat.

Also nine cookies has 7*9 = 63 grams of fat.

So the number of grams consumed will be at least 36 and no more than 63.

Which equation has a graph that is a parabola with a vertex at (–2, 0)?
MaRussiya [10]

Answer:

The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.

If the function has a positive leading coefficient, the vertex corresponds to the minimum value.

If it has a negative leading coefficient,  the vertex corresponds to the maximum valuevalue

If the vertex is located at

(–2, 0)

The possibilities are

y =  (x-2)^2

or,

y = - (x-2)^2

Since the problem tells us the answer, we adopt the positive values

Answer:

y =  (x-2)^2

P is the centroid of triangle ABC. AE=21,CD=14, and BF=11<br><br> What is the length of AP
allsm [11]

The length of AP is 14 units

Step-by-step explanation:

The centroid point of a triangle is:

  • The point of intersection of the three medians of the triangle
  • The centroid point divides each median into two segments at a ratio 2 : 1 from its vertex
  • The length of the segment from the vertex to the centroid is \frac{2}{3} of the length of the median
  • The length of the segment from the centroid to the base is \frac{1}{3} of the length of the median

Look to the attached figure

In Δ ABC

∵ D is the mid-point of AB

∵ E is the mid-point of BC

∵ F is the mid-point of AC

∵ AE , BF and CD are the medians of the triangle

∵ AE , BF and CD are intersected at P

∴ P is the centroid of the triangle

- By using the rule above

∴ AP = \frac{2}{3} AE

∵ AE = 21 units

∴ AP = \frac{2}{3} × 21

∴ AP = 14 units

The length of AP is 14 units
