Kirima is building a wall for her snow fort. She first makes a firm base out of snow, and then piles uniformly sized blocks of s

MrMuchimi

Answer:

The correct option is;

0.4 represents the height of each block

Step-by-step explanation:

The information given are;

Kirima first builds a firm base of a given height

Kirima is building her wall using uniformly sized bricks

the height of the wall she is building depends on the number of blocks stacked to form the wall

Therefore, variable that depends on other variable, which is the dependent variable, y, is the height of the wall

The independent, which determines the value of the dependent variable is the number of blocks added, x

The gradient of the equation is the height of each block = 0.4

The y-intercept is the starting value, which is the firm base of dimension, 0.6

Therefore, 0.4 represents the height of each block.

Adam and Betty start are the same point Adam walls 3 feet north while Betty walks 4 feet west. If a straight line were to be dra

Keith_Richards [23]

Answer:

5 feet.

Step-by-step explanation:

i) Adam walks 3 feet north

ii) Betty walks 4 feet west.

iii) We know that the angle between north and west is 90 degrees.

iv) Therefore we can say that distance Adam walks is the height of a right

angled triangle and the distance that Betty walks is the base of the right

angled triangle.

v) Therefore by using Pythogoras's Theorem we can calculate the length of

the line between Adam and Betty as shown

length of line between Adam and Betty = $\sqrt{3^{2} + 4^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5$ feet.

At the local clothing store all shirts were on sale for one price and sweaters for a different price. Lonnie purchased three swe

Aleonysh [2.5K]

Answer: the cost of one shirt is $28

the cost of one sweater is $23

Step-by-step explanation:

Let x represent the cost of one shirt.

Let y represent the cost of one sweater.

Lonnie purchased three sweaters and two shirts for $130. It means that

2x + 3y = 130 - - - - - - - - -1

If the sale price of a shirt was five dollars less than the sale price of a sweater, it means that

x = y - 5

Substituting x = y - 5 into equation 1, it becomes

2(y - 5) + 3y = 130

2y - 10 + 3y = 130

2y + 3y = 130 + 10

5y = 140

y = 140/5

y = 28

x = y - 5 = 28 - 5

x = 23
