An angle cannot be the complement of one angle and the supplement of another angle at the same time. is this true or false?
An angle cannot be the complement of one angle and the supplement of another angle at the same time. Then the given statement is false.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
An angle cannot be the complement of one angle and the supplement of another angle at the same time.

The required ratio is 2:1.
We have given that,
4.5:2.25
Since we have given that
We need to find the ratio in the form of n:1.
What is the ratio?
A ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6:8 and the ratio of oranges to the total amount of fruit is 8:14.
so, it becomes,
[tex]=\frac{4.5}{2.25}:1\\\\=2:1[/tex]

Donna is making a cookie recipe that calls for 1 ¾ cups of sugar. However, when she
goes to take out the measuring cups she can only find the one-half cup measuring cup. How many one-half cups will she need to fill to get the correct amount of sugar for her cookie recipe?
Answer:
3 and 1/2 half-cups
Step-by-step explanation:
We are asked to find the number of half-cups that will equal 1 3/4 cups.
__
Let the desired number be represented by n. Then we require ...
n × 1/2 = 1 3/4 . . . . some number of 1/2-cups will give 1 3/4 cups
Using a common denominator, we have ...
n × 2/4 = 7/4
Multiplying by the inverse of the coefficient of n gives ...
n × 2/4 × 4/2 = 7/4 × 4/2
n = 7/2 = 3 1/2 . . . . . simplify
That is, Donna can measure 1 3/4 cups of sugar by using her 1/2-cup measure 3 times, and filling it half-full for the final 1/4 cup she needs.
She needs 3 1/2 half-cups to get the correct amount.

Answer:
(a)no mode
(b)mean= 4
(c)median= 4
Step-by-step explanation:
the measure of centre are the mode, mean and median
mode: this is the heighest occuring number or the number with the heighest frequency.
mean: this is the average number. it's obtained by adding the data values in a set of numbers and dividing the sum by the number of data items.
meadian: this is the middle number when the data is ordered or when the data is arranged in ascending or descending order.
from the data,
mode: no number occured more than the other. therefore, there is no mode
mean = 1+2+3+4+5+6+7 = 28/7= 4
median= 1,2,3,4,5,6,7
the middle numbers is 4

3x² - 8x + 3x - 8 = 0
(Here you find two numbers which have a sum of -5 and a product of 3×-8= -24. These two numbers are -8 and 3. -8 + 3 = -5 and -8 × 3 = -24.)
(3x² - 8x) (3x - 8) = 0

What table represents a linear function
Considering the constant rate of change, it is found that table 1 represents a linear function.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the concept of the slope, we have that the rate of change of a linear function is constant, that is, when x changes by 1, y has to change always by the same amount, which happens in table 1, with a constant rate of change of 1/2 = 0.5.

Use the parabola tool to graph the quadratic function.

Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.
Answer:
See below
Step-by-step explanation:
[tex]f(x)=3x^2+6x-24\\\\f(x)=3(x^2+2x-8)\\\\f(x)+3(9)=3(x^2+2x-8+9)\\\\f(x)+27=3(x^2+2x+1)\\\\f(x)=3(x+1)^2-27[/tex]
Here, we can see that the vertex of the parabola is [tex](-1,-27)[/tex] when we compare to the equation [tex]y=(x-h)^2+k[/tex] with vertex [tex](h,k)[/tex].
A second point you could plot is the y-intercept, when [tex]x=0[/tex]:

The attached graph represents the graph of the inequality
How to determine the graph of the inequality?The points on the line are given as:
(-3,-7) and (0,2)
Start by calculating the linear equation using:

The total surface area of the remaining solid is 48(4+✓3) centimeters square.
How to calculate the surface area?Through a regular hexagonal prism whose base edge is 8 cm and the height is 12 cm, a hole in the shape of a right prism.
The formula for the total surface area will be:
= Total surface area=2(area of the base)+ parameter of base × height

Height= 8cm
Parameter of base=12(2) = 24
Area of the base= 6×✓3/4×4² = 64✓3/4
The surface area of the remaining solid will be:
= 2(64✓3/4) + 24 × 8
= 2(64✓3/4 + 192
With the hole is a rhombus prism with the following parameters:
diagonal 1 = 6, diagonal 2 = 8, height = 12
The volume is:
V1 =0.5 × d1 × d2 × h
V1 = 0.5 × 6 × 8 × 12
V1 = 96
The dimensions of the hexagonal prism are:
Base edge (a) = 8
Height (h) = 12
The volume is

Francine has a picture with a length its width. She wants to enlarge the picture to have an area of 375 in2. What will the dimensions of the enlarged picture be? Model the scenario and solve. Then, explain in at least one sentence your solution and include the reasonableness of your solution.
Answer:
25 in x 15 in
Step-by-step explanation:
Given:
Length = 3/5 the widthArea = 375 in²Let width = [tex]x[/tex]
Therefore, length = 3/5 [tex]x[/tex]
First create an equation for the area of the picture based on the given information for its width and length:
[tex]\begin{aligned} \implies \textsf{Area of original picture} & = \sf width \times length\\& = x\left(\dfrac{3}{5}x\right)\\& = \dfrac{3}{5}x^2\end{aligned}[/tex]
We are told the area of the enlarged picture is 375 in². Therefore, substitute this into the equation and solve for [tex]x[/tex] to find the width of the enlarged picture:
[tex]\begin{aligned}\textsf{Area} & = 375\\ \implies \dfrac{3}{5}x^2 & = 375\\ x^2 & =375 \cdot \dfrac{5}{3}\\ x^2 & =625\\ x & = \sqrt{625}\\ x& = 25\end{aligned}[/tex]
Therefore, the width of the enlarged picture is 25 in.
Substitute the found value of [tex]x[/tex] into the expression for length to find the length of the enlarged picture:
[tex]\begin{aligned}\sf Length & = \dfrac{3}{5}x\\\\\implies \sf Length & = \dfrac{3}{5}(25)\\\\& = 15\: \sf in\end{aligned}[/tex]
Therefore, the dimensions of the enlarged picture are 25 in x 15 in. The width is 25 in and the length is 15 in, as the length is 3/5 of the width.
