Answer:
x=5
∠ABD = 33
∠A = 115
Step-by-step explanation:
Once again here are the properties of a trapezoid:
Opposite angles are congruent
Opposite side lengths are congruent
And here is a property of a triangle:
the measure of the angles add up to equal 180
Given this information we need to find
x, ∠ABD and ∠A
First lets find x
Remember opposite side lengths are congruent
Segment AD and segment BC are opposite side lengths ( which are congruent)
That being said we create an equation to solve for x
2x = 10
step 1 divide each side by 2
2x/2=x
10/2=5
we're left with x = 5
Now lets find ∠A
∠C and ∠A are opposite angles
so ∠C≅∠A
Because ∠C = 115 ∠A also = 115
Finally lets find ∠ABD
because ∠BDC and ∠ABD are opposite angles we can find the measure of ∠BDC and get the value of ∠ABD
ΔBDC is a triangle formed within the parallelogram
That being said we can find the measure of ∠BDC using the triangle angle rule (stated previously)
That the measures of the angles in a triangle add up to equal 180
So we can find the missing angle (∠BDC) by subtracting the given angles ( which have a measure of 32 and 115) from 180
∠BDC = 180 - 32 - 115
180 - 32 - 115 = 33
so ∠BDC = 33
Meaning that ∠ABD also = 33

Stephanie puts 30 cubes in a box. The cubes are 1 inch on each side. The box holds 2 layers with 15 cubes in each layer. What is the volume of the box?
Answers
Step-by-step explanation:
Dimensions of cube = 1 in × 1in .
No. of cubes in each layer = 15 .
No. of layers = 2 .
• Therefore the volume of one cube :-
[tex]\tt \to Volume_{(cube)}= side^3 = (1 \ in.)^3 = \red{1in.^3}[/tex]
• Therefore the volume of one layer :-
[tex]\tt\to 1\ in.^3\times 15 =\orange{15\ in.^3} [/tex]
• Therefore the volume of whole box :-
[tex]\tt\to 2\ in.^3\times 15 =\orange{30\ in.^3} [/tex]
Therefore our required answer is 30 inch ³.
15x2=30 polegadas

One number is six less than a second number. Six times the first is 10 more than 4 times the second. Find the numbers
The value of the first number is
Answers
Answer:
1st number = 17
2nd number = 23
Step-by-step explanation:
x = 1st number
y = 2nd number
x = y - 6
6x = 10 + 4y
substitution method:
6(y - 6) = 10 + 4y
6y - 36 = 10 + 4y
2y - 36 = 10
2y = 46
y = 23
find 'x':
x = 23 - 6
x = 17

A 4-column table with 5 rows. The first column is labeled age (years) with entries 1, 2, 3, 4, 5. The second column is labeled given value with entries 15, 12, 9, 5, 4. The third column is labeled predicted with entries 14.8, 11.9, 9, 6.1, 3.2. The fourth column is labeled residual with entries 0.2, 0.1, 0, negative 1.1, 0.8. Which point would be on a residual plot of the data?
Answers
Answer:
3,0
Step-by-step explanation:
From the table we can say that the point which is residual plot of the data is (3,0).
What is residual plot?Residual plot shows the difference between observed and fitted values of the data. It is also known as null residual plot. In this random values in data is taken.
How to find point?We have been given the following table:
Age Value Predicted Residual
1 15 14.8 0.2
2 12 11.9 0.1
3 9 9 0
4 5 6.1 1.1
5 4 3.2 0.8
If we observe the table then we can find that the third row of fourth column contains 0 so the point which is residual plot of the data is (3,0).
Hence the point which contains the residual plot of the data is (3,0).

Answers
Answer:
The length of the third side is less than 13.
Step-by-step explanation:
In any given triangle the sum of any two sides is longer than the length of the third side.
This means that the length of the third side has to be less than 13, since that is the sum of the lengths of the two shorter sides.

Irene is making bags of trail mix for hiking club. She will use 22 ounces of walnuts, 11.2 ounces of
almonds, and 12.3 ounces of cashews. This amount makes 25 bags of trail mix. How many
ounces are in each bag?
Please help :/ if i dont finish theses questions i will go to summer school & i dont wanna go there
Answers
Answer:
In each bag there will be 1.82 ounces of mixture.
Step-by-step explanation:
Since Irene is making bags of trail mix for hiking club, and she will use 22 ounces of walnuts, 11.2 ounces of almonds, and 12.3 ounces of cashews to make 25 bags of trail mix, to determine how many ounces are in each bag you must perform the following calculation:
(22 + 11.2 + 12.3) / 25 = X
45.5 / 25 = X
1.82 = X
Thus, in each bag there will be 1.82 ounces of mixture.

What can you say about the end behavior of the function f(x) = -4x6+6x2 -52 ?
A. F(x)is an even function so both ends of the graph go in the same
direction.
B. f(x) is an even function so both ends of the graph go in opposite
directions
O C. The leading coefficient is negative so the left end of the graph
goes up.
D. The leading coefficient is negative so the left end of the graph
goes down
Answers
Answer:
A. F(x)is an even function so both ends of the graph go in the same direction.
D. The leading coefficient is negative so the left end of the graph goes down.
Step-by-step explanation:
Even function:
For every value of x, f(x) = f(-x)
In this question:
We are given the following function:
[tex]f(x) = -4x^6 + 6x^2 - 52[/tex]
Testing if it is even:
[tex]f(1) = -4(1)^6 + 6(1)^2 - 52 = -4 + 6 - 52 = -50[/tex]
[tex]f(-1) = -4(-1)^6 + 6(-1)^2 - 52 = -4 + 6 - 52 = -50[/tex]
Since f(1) = f(-1), it is even.
Since it is even, both ends of the graph go in the same direction, so option A is correct, while option B is wrong.
Options C and D:
The leading coefficient, is -4(which multiplies x with the highest exponent). Since it is negative, it goes to negative infinity as x increases, that is, the left end goes down, and option D is correct while C is not.
