A student's course grade is based on one midterm that counts as 20% of his final grade, one class project that counts as 15% of his final grade a set of homework assignments that counts as 40% of his final grade, and a final exam
that counts as 25% of his final grade. His midterm score is 76, his project score is 92, his homework score is 94, and his final exam score is 77. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume
that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B. and so on.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
