Romashka [77]3 years ago
4 0

Answer:

Step-by-step explanation:

the shape is a square (meaning all sides are equal)

CR = AR = CA=AT=AR=AT=RT=RS=ST=CS=4

the triangle in a square is an equilateral triangle meaning all sides are equal

the sum of angles in a triangle is 180°

all the angles in each triangle is 180/3 = 60°

the sum of angles in a square is 360

the angles at each angles ∠A =∠T=∠S= ∠C = 360/4 = 90°

A sample of students was asked what political party do they belong. which of the following types of graphical display would be a
inna [77]

Answer:

B. Pie chart.

Step-by-step explanation:

In this question, the students are asked what political party they belong. The best display format would be one in which the graph can be divided into parts, or percents, according to the percentage of students belonging to each political party. The graph that best describes this, distributing a group into parts, is a pie chart, and thus, the correct answer is given by option b.

Scatterplot is used when two variables correlate together, that is, there is a relationship between them, which we don't have between the number, or proportion of students belonging to each political party. Stemplot are used when there is a high number of quantitative data, which we do not have here.

Carl bought 6 hot dogs and 5 drinks and paid $25.10 Susan purchased 6 hot dogs and 3 drinks and was charged $20.10 what is the c
svetlana [45]

Answer:

Let x = the unknown cost of a single hot dog and y = the unknown cost of a single soft drink. We have two unknowns so we need two equations to find them.

Equation 1 - 10 hot dogs and 5 soft drinks cost $35; that is 10x + 5y = 35

Equation 2 - 7 hot dogs and 4 soft drinks cost $25.25; that is 7x + 4y = 25.25

First let's re-write equation 1 to solve for y:

10x + 5y = 35

5y = 35 - 10x (subtract 10x from both sides)

y = 7 - 2x (divide both sides by 5)

Next, let's substitute 7 - 2x for y in equation 2:

7x + 4y = 25.25

7x + 4(7-2x) = 25.25

7x + 28 - 8x = 25.25

-x + 28 = 25.25

x - 28 = -25.25

Solve for x, the cost of a single hot dog. Once you have that, use y = 7 - 2x to find the cost of a single soft drink.
