Answer: We need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅

PLEASEEEE GIVE BRANLIEST

Step-by-step explanation: To add 5 5/8 to a number to make 7 as an improper fraction, we need to convert 5 5/8 to an improper fraction.

To convert a mixed number to an improper fraction, we take the whole number, multiply it by the denominator of the fraction, and add the numerator. So, 5 5/8 becomes (5 x 8) + 5 / 8 = 40 + 5 / 8 = 45/8.

Now, we can add 45/8 and the number that we need to add to make 7 as an improper fraction.

45/8 + x = 7

To find x, we can subtract 45/8 from both sides of the equation:

x = 7 - 45/8

x = 1 7/8

So, we need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅

The length of the isosceles trapezoid height CE is 14 meters.

To find the length of the height CE of the isosceles trapezoid, we can use the Pythagorean theorem.

The isosceles trapezoid CE is the hypotenuse of the right triangle formed by height CE and distance AC. CE is also the height of the trapezoid. Let the length of CE be 'x'

The Pythagorean theorem states that the square of the length of the hypotenuse of a right triangle (CE) is equal to the sum of the squares of the lengths of the other two sides (AC and CE).

x² = AC² + CE²

We know that AC = 14 meters and CE = x.

So x² = 14² + x²

x² = 196 + x²

x² = x² + 196

0 = 196

x = √196 = 14

Therefore, the length of height CE is 14 meters.

Answer:

90

Step-by-step explanation:

a times by b is equal to 3600 and b divided by a is equal to 4/9 which means that a must be a mulitiple of 4 and b must be a multiple of 9. An easy multiple of 4 and a easy mulitple of 9 that times together eqaul 3600 is 90 and 40. So therefore a= 90

Answer:v=-4

Step-by-step explanation:We move all terms to the left:

-5v+6-(26)=0

We add all the numbers together, and all the variables

-5v-20=0

We move all terms containing v to the left, all other terms to the right

-5v=20

v=20/-5

The line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

On the y-axis, this value c is referred to as the intercept.

Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

y = 1/3x + 4 is the line that crosses (1,2) and is perpendicular to it.

To ascertain the equation of the line, utilize the procedures below:

Step 1: Two lines that are perpendicular to one another have the following slopes:

mm' = 1

Where the slopes of the lines are m and m'.

Step 2 - The line that is perpendicular to the line (y = 1/3x + 4) has the following slope:

1/3 * m' = -1

m' = -3

Step 3: The equation for a line passing through the points (1, 2) and having a slope of -3 is as follows:

(y - 2) = -(x - 1)

Implicate the equation above:

y = -3x + 5

Therefore, the line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).

In Euclidean geometry, an angle is a shape that is made up of two rays, known as the hood's sides, that meeting at a middle point known as the wall's apex. Two rays may combine to form an angle in the planes where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two photons or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, sometimes known as two sides of the angle, converge.

Step-by-step explanation:

You want to know the pre-tax price if the price with 5% tax added is $21.

The added tax is 5% of the original amount (x), so the amount with tax added is ...

  $21 = x + 0.05x = 1.05x

  $21/1.05 = x = $20 . . . . . divide by the coefficient of x

The cost before tax was added was $20.

Step-by-step explanation:

Percentage left after the tax percentage is

100%-5%=95%

95% is equal to 95/100 = 0.95

therefore, the cost after tax divided by the percentage that is left after the tax percentage

The value of the combined function f(g(x)) will be -16x^2+88x-120.

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

There are several types of functions in math. Some important types are:

Injective function or One to one function: When there is mapping for a range for each domain between two sets.

Surjective functions or Onto function: When there is more than one element mapped from domain to range.

Polynomial function: The function which consists of polynomials.

Inverse Functions: The function which can invert another function.

Now,

Given functions are f(x)=1-x^2 and

g(x)=11-4x

Therefore,

the combined function will be f(g(x))=1-(11-4x)^2

=1-121-16x^2+88x

Hence,
