If you have a 77.2% and you got 34% on a test and it’s worth 60% of your grade, what would you grade be now?

Mathematics
1 answer:
Rzqust [24]1 year ago
4 0

Answer:

51.28%

Step-by-step explanation:

since the test is worth 60% of your grade, the rest is worth 40%

calculate your new grade by multiplying each grade percent (as written) by the percent of your grade (as a decimal):

   77.2(0.4) = 30.88

   34(0.6) = 20.4

then add them together: 30.88 + 20.4

Answer:

193.14m^2

Step-by-step explanation:

Rectangle

A=wl\\=15.3*11.1\\=169.83m^2

Triangle

A=\frac{ab}{2} \\=\frac{11.1*4.2}{2}\\ =23.31m^2

Add both together

169.83+23.31\\=193.14m^2

A species of phytoplankton measures about 2 × 10−6 in. A grain of sand measures about 1 × 10−4 in. About how many times longer i
Gennadij [26K]

Answer:

B. 50 times greater

Step-by-step explanation:

Given;

size of phytoplankton = 2 × 10⁻⁶ in

size of sand grain = 1 × 10⁻⁴ in

Determine how many times longer the grain of sand is than the phytoplankton.

Divide the sand size by the phytoplankton size, to find out how much greater the sand is.

This can be done by equating it as follows;

2 × 10⁻⁶ (y)  = 1 × 10⁻⁴

y = \frac{1*10^{-4}}{2*10^{-6}} \\\\y = 50

Therefore, the grain of sand is 50 times greater than the phytoplankton

B. 50 times greater

If line T is a transversal of lines I and m, name the angel relationship of the given angle pairs
Crazy boy [7]

Answer:

a.Corresponding angles

b.Alternate exterior angles

c.Consecutive interior angles

Step-by-step explanation:

a.\angle 1,\angle3 are corresponding angles.

  • Two angles on the same side of the transversal either below or above of the two lines are corresponding angles.

b.\angle 4,\angle8 are alternate exterior angles.

  • Pair of angles in which one arm of each of the angles lies on opposite sides of the transversal.

c.\angle 2,\angle3 are consecutive interior angles.

Consecutive interior angles are also called co-interior angles.

  • Angles which are lying on the same side of a transversal cutting across the the two lines which are parallel.

So the pair of 1\ and\ 3 are corresponding angles the pair of 4\ and\ 8 are alternate exterior angles,the pair of 2\ and\ 3 are consecutive interior angles.

Let 3x^2+kx+4. determine all values of k such that the quadratic equation f(x) =0 has one real root
user100 [1]
//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root

Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3
