Answer:

$2,750 = $200x + $750

10 cars to meet the goal

Step-by-step explanation:

We will pull details we need to solve out of the question:

     If her goal is to make 2,750 dollars, the money earned must equal at least $2,750.

     If she's already made $750, then we can subtract that from what is needed left to make (or add it to what needs to be made).

     Finally, she makes $200 per car. Let x equal the number of cars she sells.

Next, we will write an equation:

     $2,750 = $200x + $750

Lastly, we will solve this equation.

     $2,750 = $200x + $750

     $2,000 = $200x

     10 = x

           She needs to sell 10 cars to meet her goal.

The most pieces of fabric that can be used is 144 pieces, making a quilt with 12 pieces on each side.

The square is a term to refer to a geometric figure that is characterized by being a type of parallelogram with four sides of equal length. A square is a regular polygon that has all its sides equal, and its interior angles measure 90º.

To identify the number of square pieces that I can use to make a square quilt, I must keep in mind that to create a square quilt I must put the same number of pieces on each side of the quilt so that it forms a perfect square.

To identify the maximum number of pieces needed, we can try taking the square root of 150, 149, 148, 147... until the result is a integer number (no decimals). In this case the first integer that appears is 12 by taking the square root of 144 as shown below.

[tex]\sqrt[2]{144} = 12[/tex]

This means that to make a square quilt we must use 144 pieces in total and place 12 pieces on each side of the square. Additionally we can state that the side length of this quilt is 48 inches because each piece measured 4 inches on a side.

4 inches × 12 = 48 inches.

If Upper pointing arrow with height of 11 and length of 9. Rectangular base of arrow has length of 7 and height of 8. All units are in centimeters. The area of the arrow by decomposing it into rectangles and triangles is: 69.5 square centimeters.

First step is to determine the Area of triangle using this formula

Area of triangle= ½×breadth ×height

Where:

Breadth=9

Height of triangle= 11 - 8

Height of triangle = 3cm

Area of triangle= ½ × 9 × 3

Area of triangle = 13.5 cm²

Second step is to determine the area of rectangle

Area of rectangle= length × breadth

Area of rectangle= 8 × 7

Area of rectangle= 56 cm²

Third step is to determine the total area

Total area=Area of triangles+ Area of rectangle

Total area = 13.5 + 56

Total area= 69.5 cm²

Therefore the area of the arrow by decomposing it into rectangles and triangles is: 69.5 square centimeters.

Step-by-step explanation:

juanita should use 0.625 to update her report.

given that the pitcher threw 384 pitches  and used fastball 240 times.

according to the information

240÷ 384

To divide a decimal number by a whole number, long divide as you would with two whole numbers, but put the decimal point in the answer at the same place it is at in the dividend. If it does not divide evenly, add a 0 to the end of the dividend and continue dividing until there is no remainder.

How do you divide decimals step by step?

The step-wise procedure for dividing decimals by a whole number is given below:

Step 1: Write the given division expression in the standard form.

Step 2: Now, we have to divide the decimal number's whole number part by the divisor.

Step 3: Place the decimal point in the quotient above the dividend's decimal point and then bring down the tenths' digit.

Step 4: If the tenth digit of the obtained dividend cannot be divided by the divisor, write 0 in the quotient and in front of the tenths' digit. Otherwise, proceed with the division process.

Step 5: Repeat the above step and keep adding the zeroes in the dividend until 0 is obtained in the remainder.

240 ÷ 384

⇒ 0.625

so juanita should use 0.625 to update her report

Answer:

Step-by-step explanation:

Define the variables:

Let the two numbers be x and y, where x > y.

Given information:

Create two equations from the given information and defined variables:

[tex]\begin{cases}x = 4y + 1\\x + y = 106\end{cases}[/tex]

Substitute Equation 1 into Equation 2 and solve for y:

[tex]\implies (4y+1)+y=106[/tex]

[tex]\implies 4y+1+y=106[/tex]

[tex]\implies 5y+1=106[/tex]

[tex]\implies 5y+1-1=106-1[/tex]

[tex]\implies 5y=105[/tex]

[tex]\implies \dfrac{5y}{5}=\dfrac{105}{5}[/tex]

[tex]\implies y=21[/tex]

Substitute the found value of y into the second equation and solve for x:

[tex]\implies x+21=106[/tex]

[tex]\implies x+21-21=106-21[/tex]

[tex]\implies x=85[/tex]

The single logarithm for the given expression (2 log₄6 - log₄9) is 1.

The given logarithmic expression is 2 log₄6 - log₄9.

Use the ability rule of the logarithm logₐ(Xⁿ) = n logₐ(X), to get 2

log₄6 - log₄9= log₄6² - log₄9

= log₄36 - log₄9          (Since 6² = 36)

Use the quotient rule of the logarithm logₐ(X/Y) = logₐ(X) - logₐ(Y), to get:

log₄36 - log₄9= log₄(36/9) = log₄(4)

The measure of the z value from the given figure is 6 2/3.

We need to find the unknown value for the given figure.

In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec(or csc), and cot in short. Trigonometric ratios can be used to determine the ratios of any two sides out of a total of three sides of a right-angled triangle in terms of the respective angles.

Using trigonometric ratios we can find the z value.

From the given figure, tan θ = 4/6 ----(I) and also tan θ = z/10 ----(II)

Now, equation (I) = (II)

⇒ 4/6 = z/10

⇒ 4 × 10 = z × 6

⇒ 6z = 40

⇒ z = 40/6

⇒ z = 20/3

⇒ z = 6 2/3

Therefore, the measure of the z value from the given figure is 6 2/3.

Logarithms are another technique to express exponents. An integer's baseline logarithm matches another number. A logarithm is the inverse of exponentiation.

Given : 4 e x⁻¹=64

STEPS USING DEFINITION OF LOGARITHM

the range of the function g(x) will be y ≤ 0.

We know that the absolute value function g(x) can be written as:

g(x) = a*|x|

Remember that the range of f(x) = |x| is y > 0, and a is a negative number, so the function is reflected over the horizontal axis.

Then the maximum value will be when x = 0, then:

g(0) = a*|0| = 0, that is the maximum.

And then the function opens downwards. Then the range will be y ≤ 0.
