A. she should find the squares of numbers between 7.4 and 7.5

Josiah and Mia have $42.5 and $59.5 in the beginning respectively.

Let us assume x is the amount that Josiah have in the beginning.

y is the amount that Mia have in the beginning.

from the question

if Mia gives $8.50 to the Josiah then both have equal amount which means

y - 8.50 = x + 8.50 ........................(1)

now Mia has double If Josiah gives Mia $8.50 which means

y + 8.50 = 2(x - 8.50)

y + 8.50 = 2x - 17 ..........................(2)

now subtract equation (1) from equation (2)

(y - 8.50) - (y + 8.50) = (x + 8.50) - (2x - 17)

y - 8.50 - y - 8.50 = x + 8.50 - 2x + 17

-17 = -x + 25.5

-x = -25.5-17

x = 42.5

now put x value into equation (1) to obtain y value

y - 8.50 = x + 8.50

y - 8.50 = 42.5 + 8.50

y = 51 + 8.50

y = 59.50

Hence, the Josiah and Mia have $42.5 and $59.5 in the beginning respectively.

Answer:

Let 2w = the length

P = 2l + 2w

132 = 2(2w) + 2w

132 = 4w + 2w

132 = 6w

22 feet = w

2w = 2(22) = 48 inches

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all four vertices are equal to 90 degrees.

The length of the rectangle is 49.5 inches.

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all four vertices are equal to 90 degrees.

We have,

Length of a rectangle = L

Width of the rectangle = W

L = 3W _____(1)

The perimeter of the rectangle:

P = 2 ( L + W )

132 = 2 ( L + W )

132 / 2 = L + W

66 = L + W

From (1),

66 = 3W + W

66 = 4W

66/4 = W

W = 16.5 inches.

From (1),

L = 3 x 16.5

L = 49.5 inches

Thus the length of the rectangle is 49.5 inches.

3.)-199+72k

4.)-7pq+6p+q+4

5.)-7c+9

6.)-110t+160

Step-by-step explanation:

The slope-intercept form of the equation of the line described is y = -10/9x + 4/3.

Given the following data:

Points on x-axis = (-6, 4).

Points on y-axis = (8, -1).

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope = (4 + 6)/-1 - 8)

Slope = -10/9

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

At point (-6, 8), we have:

8 = -10/9(-6) + c

8 = 60/9 + c

72 = 60 + 9c

9c = 72 - 60

c = 12/9

c = 4/3

Therefore, the slope-intercept form of the equation of the line described is y = -10/9x + 4/3.

We can see that that the data is plotted on a scatterplot. The scatter plot has a vertical and a horizontal axis. It is evident that the horizontal axis plots the time while what is plotted on the vertical axis is the amount of flour.

As we can see, the relationship between the time and the amount of flour is negative. This can be seen from the shape of the plot as it is displayed in the image attached.

Looking at the shape of the graph, we can see that; The amount of flour when the time is zero seconds is 630 grams. As time increases, the amount of flour in the machine decreases. This corresponds to a negative relationship between the two variables.

The negative relationship also implies that we have to expect to have a negative slope. The rate at which the amount of flour increasing is; 210 – 630/3 – 0 = -140 grams/minute

Answer:

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run. the form of a rise and run looks like a fraction. The slopes of perpendicular lines are negative reciprocals of one another. For example, a line with a slope of 23 will be perpendicular to a line with a slope of −32 . A line with a slope of -5 will be perpendicular to a line with a slope of 15 .

I hope I helped with your essay <3

Answer:

The slope is finding the rate of increase or decrease in a line. The slope of a line can be helpful in multitudes of problems. One example is the fact that if you multiply the slope of two lines that are perpendicular to each other, you get -1. This way, you can find the slope of a perpendicular line without actually having to calculate it. Another way to use slope is with parallel lines. Parallel lines have the same slope and you can find the equation of another parallel lines just by knowing its slope and one point on that line.

Using supplementary angles, it is found that the measure of angle QRT is of 47º.

For this problem, we have a straight line segment QS divided by an inclined segment RT. The measures of the angles are given as follows:

When two angles have measures adding to 180º, they are called supplementary.

In this problem, due to the inclined segment, angles QRT and TSR are supplementary, and we can solve for x as follows:

3x + 5 + 10x - 7 = 180

13x = 182

x = 182/13

x = 14.

Hence the measure of angle QRT is found as follows:

m<QRT = 3(14) + 5 = 47º.

Answer:

The answer is No Solution.

Step-by-step explanation:

We can't add the two systems, so let's look for x. We would need to multiple them by (-6) and 2, which are the numbers in front of x. One must be a negative.

(2x + 3y = 7) * (-6)
(6x + 9y = 6) * 2

_____________

(-12x) + (-18y) = -42

(12x + 18y = 12

Both the x and y cancel each other out, and we're only left with -42 and 12, which doesn't really solve for x.

You can check the answer by checking for y. So, this time, we'll multiply the equations by (-9) and 3, which are the numbers in front of y.

(2x + 3y = 7) * (-9)

(6x + 9y = 6) * 3

___________

(-18x) + (-27y) = -63

18x + 27y = 18

Both x and y cancel out, and we're left with -63 and 18.

In the expression 3(19 + 2), the product of 3 and the first term is 57.

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors. Mathematically, the product of two numbers 'a' and 'b' is -

M = a x b

or

M = a + a + a + a +...... b times

Given is the following expression -

3(19 + 2)

We can solve the given expression using the distributive law of addition which says, for three numbers A, B and C →

A(B + C) = (A x B) + (A x C)

Using the distributive law of addition -

3(19 + 2)

3 x 19 + 3 x 2

57 + 6

In the expression, 19 is the first term, so the product will be 57.

Therefore, in the expression 3(19 + 2), the product of 3 and the first term is 57.

The sine function h(x) is given by:

h(x) = 5sin(π/4(x - 0.5)) - 3.

The cosine function is defined as follows:

g(x) = asin(bx+c)+d.

The coefficients have these following roles:

For this function, we have that:

Hence the coefficient a is of 5, as:

a = -3 - (-8) = -3 + 8 = 5.

A standard cosine function with amplitude 5 would vary between -5 and 5, with midline at 0, hence the coefficient d is of d = -3.

The minimum value and midline form one-fourth the period, hence, since the period is of 4 x (0.5 - (-1.5)) = 8, we have that:

2π/B = 8

B = π/4

The standard midline is at x = 0, but for this function function it is at x = 0.5, meaning that the function was shifted 0.5 units right, hence c = -0.5.

Thus the function is given by:

h(x) = 5sin(π/4(x - 0.5)) - 3.

The graph at the end of the answer shows that the function has the desired features.

the circumference of circle of area 2122.64 sq. cm. is 163.36 cm.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Area of circle is calculated using formula :

A = πr²

It is given that Area of circle is 2122.64 sq cm. then the radius will be :

A = πr²

2122.64 = π(r)²

r = √2122.64 / π

r = 26 cm

Now, calculating the circumference of the circle using formulae :

C = 2πr

C = 2π x 26

C = 163.36 cm

Therefore, the circumference of circle of area 2122.64 sq cm is 163.36 cm.
