Nataly_w [17]

Answer:

0.80A + 0.92B = 63 .....1

A + B = 75 ......2

Step-by-step explanation:

Let A and B represent the total possible score in part A and B respectively;

Analysing each sentence of the question;

Sam scored 80% on Part A of a math test and 92% on part B of the math test. His total mark on the test was 63

80% of A + 92% of B = 63

0.80A + 0.92B = 63 ......1

The total possible marks for the test was 75;

A + B = 75 .....2

So, equation 1 and 2 provides a set of simultaneous equations that can be used to represent and solve the situation.

Solving the simultaneous equations, we will arrive at;

Part A = 50

Part B = 25

Lynn plotted point G, 3 units to the left and 2 units above point F . Where did Lynn plot point G ?
bekas [8.4K]

Answer:

(2, 6)

Step-by-step explanation:

Point G has a coordinate of x = 5, and y = 4, that is (5, 4).

If Lynn plots point G, such that:

G is 3 units to the left of point F, the x-coordinate of point G = 5 - 3 = 2

G is 2 units above point F, the y-coordinate of point G = 4 + 2 = 6.

Therefore, Lynn plotted point G at x = 2, and y = 6. Which is (2, 6)

Gretchen has a set of blocks of heights 1, 2, and 4-centimeters. Imagine stacking the blocks one on top of the other to make a t
notsponge [240]

Answer:

t_{n}=t_{n-1}+t_{n-2} +t_{n-4}

Step-by-step explanation:

t_{n}=multiple ways to climb a tower

When n = 1,

tower= 1 cm  

t_{1}= 1

When n = 2,

tower =2 cm   

t_{2}= 2

When n = 3,

tower = 3 cm

it can be build if we use three 1 cm blocks

t_{3} = 3

When n = 4,

tower= 4 cm

it can be build if we use four 1 cm blocks

t_{4} = 6

When n > 5

tower height > 4 cm

so we can use 1 cm, 2 cm and 4 cm blocks

so in that case if our last move is 1 cm block then t_{n-1} will be

n —1 cm

if our last move is 2 cm block then t_{n-2} will be

n —2 cm

if our last move is 4 cm block then t_{n-4} will be

n —4 cm

 

t_{n}=t_{n-1}+t_{n-2} +t_{n-4}
