Answer:

? = 9

Step-by-step explanation:

First, deduce the length top part of the left side.

8 - 6 = 2

So, we can now label that top part 2.

Finally, compare the ratios of the sides.

2 : 6 = 3 : ?

2 * (3/2) : 6 * (3/2) = 3 : ?

? = 6 * (3/2)

? = 9

A number which represents the location of the snail in feet is 1/2 feet.

In Mathematics, a number line can be defined as a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.

This ultimately implies that, a number line primarily increases in numerical value towards the right from zero (0) and decreases in numerical value towards the left from zero (0).

Note: The opposite of a given number on a number line is the number on the other side of zero (0) and the same distance from zero (0).

Based on the information provided above, we can reasonably infer and logically deduce that the snail is located at the opposite of -1/2 foot on the number line. Therefore, the opposite of -1/2 foot would be 1/2 foot.

The angle x of the triangle is 68 degrees and the side y is 7.5 units.

The triangle ABC is a right angle triangle because it has one angle as 90 degrees. The sum of the angles in the triangle is 180 degrees.

The angle ECD is congruent to angle ACB(vertically opposite angles).

Therefore,

∠ECD ≅ ∠ACB

Hence,

x = 180 - 90 - 22

x = 68 degrees.

using trigonometric ratios, let's find y

cos 22 = adjacent / hypotenuse

sin 22 = 2y - 1 / 15

cross multiply

15 cos 22 = 2y - 1

2y - 1 = 13.9077578185

2y = 13.9077578185 + 1

2y = 14.9077578185

divide both sides by 2

y = 14.9077578185 / 2

y = 7.45387890925

Therefore,

y = 7.5 units

The percentage of the blue blanket will be 25%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that a bin at a department store contains blue and red blankets. The ratio of blue blankets to red blankets is 4 to 1.

The percentage of the blue blanket will be calculated as,

Percentage = 1 / 4

Percentage = 0.25

Percentage = 0.25 x 100 = 25%

The equation is 26 = 13.5 + 2.5 m, and the value of m is 5, so option C is correct.

Equations are statements in mathematics containing the equals (=) sign flanked on either side by two algebraic expressions. The relationship between the expressions printed on the left and right sides is shown to be equal in this way.

Given:

Twenty-six equals the sum of [tex]13.5[/tex] And the quotient of a number and [tex]2.5.[/tex]

Write the equation in mathematical form,

26 = 13.5 + quotient × 2.5

Assume the quotient is m then,

26 = 13.5 + 2.5 m,

Solve the equation to get the value of m,

26 - 13.5 = 2.5 m,

m = 5

Therefore, the equation is 26 = 13.5 + 2.5 m, and the value of m is 5.

She can spend a maximum of $2763.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression.

The credit card works as there can be a negative balance in the card. For example if Sally has a shortage of money and she is in need of some, she can take money from her credit card and then repay it later.

Sally already has $763 in her possession in this situation, and her credit card can only have a $2000 balance.

So Sally can spend $763 which she already has in her hand and then spend a maximum of $2000 using her credit card.

Given,

The equation written in slope-intercept form withn a slope of -5 and a y-intercept of 5 is y = -5x + 5

intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

equation of straight line in slope intercept form is given as

y = mx + c

where m = slope and c = y-intercept

from the question, it means m = -5 and c = 5

substituting we have,

By solving equations, we know that the number of apples and mangoes purchased is 8 and 2, respectively.

In a mathematical equation, the equals sign is used to express that two expressions are equal.

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

For instance, the expressions 3x + 5 and 14 make up the equation 3x + 5 = 14, with the word "equal" separating them.

So, we know that:

Apple and mango are worth $13.50.

Each mango costs $0.75, but each apple costs $1.50.

Let the number of apples be x and the number of mangoes be y, so that:

1.50x + 0.75y = 13.50

Fewer apples than mangoes by six That is to say,

x = y + 6

x - y = 6

The two resulting equations are:

1.50x + 0.75y = 13.50

x - y = 6

The simultaneous equation's solution provides

x = 8

y = 2

Therefore, by solving equations, we know that the number of apples and mangoes purchased is 8 and 2, respectively.

Angle ACD is congruent to angle ADC by transitive equality if angles 1 and 2 are both ACD because angle ACB is congruent to angle ADE in the step above. Therefore, angle 1 equals angle 2, as you can see.

An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

Here,

Given that segments AB and AE are congruent, the triangle ABE is required to be isosceles by definition.

As a result, angle ABC must be similar to angle AED, again in accordance with the definition of an isosceles triangle.

Consequently, triangle ABC must be congruent to triangle AED by SAS as you have been informed that segments BC and DE are congruent. Right now, it's unclear to you whether angle 1 is ACB or ACD.

Assuming it is ACB, CPCT shows that ACB is congruent to ADE. Angle 1 equals angle 2, so there you have it. Since angle ACB is supplementary to angle ACD and angle ADE is supplementary to angle ADC.

Since angle ACB is congruent to angle ADE from the step above, angle ACD is congruent to angle ADC by transitive equality if angle 1 and angle 2 are both ACD. Angle 1 equals angle 2, so there you have it.

We have,

single appearance = $250,000

sales =$1,250,000

concession receipts = $400,000

Total amount = single appearance + (10% of sales) + (10% ofconcession receipts)
