Answer: 178.25

Step-by-step explanation:

124.25 + 223.56 - 89.56 - 80.00

Answer: $178.25

Step-by-step explanation: Your balance on May 15 is $124.25. On May 20, you deposit $223.56, which increases your balance to $124.25 + $223.56 = $347.81. You then write a check for $89.56, which decreases your balance to $347.81 - $89.56 = $258.25. Finally, you withdraw $80.00 from an ATM on May 25, which decreases your balance to $258.25 - $80.00 = $178.25. Therefore, your current balance is $178.25.

As per the congruence theorem, we have proved that ΔABC ≅ΔDEF.

In math congruence theorem states that if all the three sides of one triangle are equal to all the three sides of another triangle, then both the triangles are congruent to each other.

Here we need to prove ΔABC ≅ΔDEF by using the congruence theorem.

Here we have given that ΔABC and ΔDEF,

=> ∠B≅∠E [right angle]

So, we have obtained that

=> ∠A≅∠D

As we know that there is two angles and one non included side of ΔABC is congruent the two corresponding angles and one non- included side of ΔDEF, therefore, by AAS congruence rule.

So, based on the given fact we have identified that

=> ΔABC ≅ΔDEF

Therefore, the AAS congruence postulate defined that the triangles are congruent if two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.

The perimeter is:

If the perimeter is less than 20, then the inequality is:

Answer:

x < 4

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

Therefore, from inspection of the triangle:

⇒ Perimeter = 4 + 9 + x + 3

⇒ Perimeter = x + 16

If the perimeter is less than 20 meters then:

⇒ x + 16 < 20

Solve the inequality:

⇒ x + 16 - 16 < 20 - 16

⇒ x < 4

What is the quadratic function?

In mathematics, a polynomial of degree two in one or more variables is referred to as a quadratic polynomial. A quadratic polynomial defines the polynomial function known as a quadratic function.

We have,

f(x) = -3(x-3)² + 1

by simplifying the equation above

-3(x² -6x + 9) + 1 = 0

-3x² + 18x - 27 + 1 = 0

-3x² + 18x - 26 = 0

By calculating the quadratic equation we get

[tex]x=\frac{-b \pm \sqrt{b^2 - 4ac} }{2a}[/tex]

[tex]x=\frac{ -18 \pm \sqrt{18^2 - 4(-3)(-26)} }{2(-3)}[/tex]

[tex]x= 3 \pm \frac{\sqrt{3} }{3}[/tex]

x = 2.42265,      x = 3.57735

so the points are (0, 0) and (2.4, 3.6)

The graph crosses the x-axis at (2.4, 3.6)

Hence, the graph has 2 x-intercepts.

A small airplane can fly about 124.8 miles in one hour.

In this question, we have been given a small airplane flew 104 miles in 50 minutes.

We need to find the distance the airplane would cover in an hour.

Let a small airplane can fly 'x' miles in one hour.

We know that 1 hour = 60 minutes

Using proportionality we get an equation,

x/104 = 60/50

We solve above equation.

50x = 60 * 104

x = 6240/50

x = 124.8

So, the distance would be 124.8 miles

In the given question, we have given the radius of the circle and we need to find the circumference of the same.

To need to find the circumference, we must recall this formula

Circumference of circle = [tex]2\pi r[/tex]

Now, according to the question

Radius = 19.5 cm

Circumference = 2 * [tex]\pi[/tex] * 19.5

                         = 2 * 3.14 * 19.5       (Taking [tex]\pi[/tex] = 3.14)

                         = 122.5 cm

Therefore, the circumference of a circle with radius 19.5 cm is 122.5 cm

There are 210 sequences for 7 church bells to rung with the given conditions. Using permutations, the required number of sequences is calculated.

A sequence or arrangement that can be framed by taking some or all of a finite set of things (or objects) is called a permutation.

The formula for finding the number of such arrangements is,

ⁿPₓ = n!/(n - x)!

It is given that, a church's bell tower has 7 bells. 3 of them will ring in a sequence before each service and no bell is rung more than once.

So, the number of sequences that the bells will form is calculated by using the permutations formula. I.e., ⁿPₓ = n!/(n - x)!

Here, n = 7; x = 3

Then,

ⁿPₓ = n!/(n - x)! ⇒ ⁷P₃ = 7!/(7 - 3)! = 7!/4!

⇒ ⁷P₃ = (7 × 6 × 5 × 4!)/4! = 7 × 6 × 5 = 210

Therefore, there are 210 sequences for ringing the bells.

The circumference of the scaled circle is half the circumference of the original circle and the area of the scaled circle is half the area of the original circle.

What is the scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2. The new figure we receive will resemble the first figure, but every dimension will be double that of the first rectangle. The scale factor in this case will be denoted by the number 2.

Let us take the radius of the circle to be r

We know that circumference = 2πr and the area of a circle is πr²

As, Scale factor = Original circle / Scaled circle

From the question, scale factor = 2

Thus,

2 = Circumference of the Original circle / Circumference of the Scaled circle.

⇒ Circumference of the Scaled circle = (1/2) * Circumference of the Original circle

For the area as well, scale factor = 2

2 = Area of the Original circle / Area of the Scaled circle

⇒ Area of the scaled circle = (1/2) * Area of the original circle

Thus,

The circumference of the scaled circle is half the circumference of the original circle and the area of the scaled circle is half the area of the original circle.

For the function, y = log₄ (x + 16) - 1, it has x-intercept of -12 and y-intercept of 1.

Logarithmic functions are functions expressed in another way for exponential functions. It is the power to which any number should be raised to yield other values.

Logₐ x = n can be written in exponential form as x = aⁿ.

y = log₄ (x + 16) - 1

x-intercept is the x-coordinate of the point when y = 0.

0 = log₄ (x + 16) - 1

For the left hand side to be equal to 0, the term log₄ (x + 16) must be equal to 1.

log₄ (x + 16) = 1  

⇒ x + 16 = 4       (∵ logₐ a = 1)

⇒ x = -12

y-intercept is the y-coordinate of the point where x = 0.

y = log₄ (0 + 16) - 1

y =  log₄ (16) - 1

y =  log₄ (4²) - 1

logₐ mⁿ = n logₐ m

⇒ y = 2 log₄ (4) - 1

⇒ y = 2 - 1     (∵ log₄ (4) = 1)

⇒ y = 1

Hence, the function y = log₄ (x + 16) - 1 has x-intercept of -12 and y-intercept of 1.

Total length of the fence = 300 foot

Consider the width of the rectangular yard = x

The length of the rectangular yard = x + 10

The perimeter of the rectangle = 2(l + w)

Where l is the length and w is the width

Substitute the values in the equation

300 = 2(x+10 + x)

300 = 2(2x + 10)

4x + 20 = 300

4x = 300 - 20

4x = 280

x = 280/4

x = 70 foot

To test the null hypothesis that there is no difference in parents' wealth for the different levels of schooling, a one-way ANOVA (analysis of variance) test should be used.

To compare the means of two or more groups, statisticians employ the analysis of variance (ANOVA) test. It is used to assess whether there are any significant variations in the means of the groups and to pinpoint which group or groups have significantly different means. The null hypothesis, according to which there is no difference between the group means, is evaluated using the ANOVA test using the F-statistic. If the F-statistic is significant, at least one of the groups has a mean that differs from the others in a meaningful way. To examine how several treatments or circumstances affect a response variable, investigations frequently utilize an ANOVA. It can also be used in non-experimental research to compare the means of different groups.

From the question, we have the following parameters that can be used in our computation:

y = 2x + 5

y = -1/4x + 0.5

So, we have the following representation

-1/4x + 0.5 = 2x + 5

Collect the like terms

So, the equation becomes

2x + 1/4x = 0.5- 5

So, we have

The area of the resulting shape if a circle with a 12-inch diameter is folded in half and then folded in half again is 28.26 square inches

If a circle with a 12-inch diameter is folded into half and then folded into half again the circle will become a quadrant.

So,

The area of a quadrant is area of a circle divided by 4

Area of a quadrant = πr² / 4

Diameter of a circle = 2r

12 = 2r

divide both sides by 2

r = 6 inch

Area of the quadrant = 3.14 × (6)²/4

Area of the quadrant = (3.14 × 36) /4
