Answer:
TUV=52
Step-by-step explanation:
2z+65+59+26z=180
28z+124=180
28z=56
z=2
26*2=52
Answer:
TV
Step-by-step explanation:
The sum of the angles of a triangle are 180
z+59 + z+65 + 26z = 180
Combine like terms
28z + 124 = 180
Subtract 124
28z = 180-125
28z =56
Divide by 28
28z/28 = 56/28
z=2
The smallest side is opposite the smallest angle
26*2 = 52
<u is the smallest angle so TV is the smallest side

The solution for the given system of linear equations is (4, 3).
Given that, here is a graph of y=7-x for values x from 0 to 7.
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
The given system of linear equations
y=7-x -------(I) and y=x-1 -------(II)
From equation (I) and (II),
7-x=x-1
⇒ 2x=8
⇒ x=4
So, y=7-x=3
Thus, (x, y)=(4, 3)
Therefore, the solution for the given system of linear equations is (4, 3).

In 1000 sq. meter of land a farmer cultivated 765 kg of rice with the wastage of 23.5%.I) Find the weight of the wastage. II) Find the weight and percentage of rice cultivated.
Answers
Answer:
i. weight of wastage(kg) = 179.775 kg
ii. weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg
percentage of rice cultivated = 100 - 23.5 = 76.5%
Step-by-step explanation:
A land of 1000 sq. meter is used to cultivate 765 kg of rice with wastage of 23.5%.
i. The wastage in percentage is 23.5% but the weight of the wastage in weight is 23.5% of 765 kg
weight of wastage = 23.5/100 × 765
weight of wastage = 17977.5/100
weight of wastage(kg) = 179.775 kg
ii. weight and percentage of rice cultivated.
weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg
percentage of rice cultivated = 100 - 23.5 = 76.5%

Answers
Answer:
See Explanation
Step-by-step explanation:
(a)For matrices A and D, given that: [tex]AD=I_m[/tex].
We want to show that [tex]\forall b \in R^m[/tex], Ax=b has a solution.
If Ax=b
Multiply both sides by D
[tex](Ax)D=b \times D\\\implies (AD)x=bD$ (Recall: AD=I_m)\\\implies I_mx=Db $ (Since I_m$ is the m\times m$ identity matrix)\\\implies x=Db[/tex]
This means that the system Ax=b has a solution.
(b)Matrix A has a pivot position in each row where each pivot is a different column. Therefore, A must have at least as many columns as rows.
This means A cannot have more rows than columns.
Identify the Minimum value of the function y=x^2+6x+ 9
Answers
====================================================
Explanation:
You can factor x^2+6x+9 into (x+3)^2, which turns into 1(x - (-3) )^2 + 0
So y = x^2+6x+9 becomes y = 1(x - (-3) )^2 + 0
That matches with vertex form y = a(x-h)^2 + k
The vertex is (-3,0). The y coordinate of the vertex directly tells us the minimum value. We know we have a minimum because a = 1 is positive. If a < 0, then we'd have a max y value instead.
-------------------
Alternatively, compare y = x^2+6x+9 to the form y = ax^2+bx+c
We see that a = 1, b = 6, c = 9
The x coordinate of the vertex is
h = -b/(2a)
h = -6/(2*1)
h = -3
The x coordinate of the vertex is x = -3. Plug this into the original equation to find the y coordinate of the vertex
y = x^2 + 6x + 9
y = (-3)^2 + 6(-3) + 9
y = 9 - 18 + 9
y = -9 + 9
y = 0
The y coordinate of the vertex is y = 0. This is the smallest y output possible.
AC=4, AE=7, AD=10, what is the length of AB?
A: 1 3/7
B: 2 1/2
C: 5 5/7
D: 17 1/2
Answers
Answer:
C. [tex] AB = 5\frac{5}{7} [/tex]
Step-by-step explanation:
When two polygons are considered similar, the ratio of their corresponding sides would also be equal.
Since ∆ABC and ∆ADE are similar, [tex] \frac{AE}{AC} = \frac{AD}{AB} [/tex]
[tex] \frac{7}{4} = \frac{10}{AB} [/tex]
Cross multiply
[tex] 7*AB = 10*4 [/tex]
[tex] 7*AB = 40 [/tex]
Divide both sides by 7 to find AB
[tex] \frac{7*AB}{7} = \frac{40}{7} [/tex]
[tex] AB = \frac{40}{7} [/tex]
[tex] AB = 5\frac{5}{7} [/tex]

if U is the midpoint of CB, CU=18, and CB= 2x-10, then find x
Answers
Answer:
x = 23
Step-by-step explanation:
CU + UB = CB
Since U is the midpoint that means CU = UB = 18
18+ 18 = 2x-10
36 = 2x-10
Add 10 to each side
36+10 = 2x
46 =2x
Divide by 2
23 = x
Answer:
x = 23Step-by-step explanation:
CB/2 = CU
CB = (2)CU
2x - 10 = (2)18
2x - 10 = 36
Add 10 on both sides.
2x = 46
Divide both sides by 2.
x = 23
Which equation represents a circle that contains the point (-5, -3) and has a center at (-2, 1)?
Distance formule: (x2 - x1)2 +(y2-y1)2
(x-1)2 + (y + 2)2= 25
(x + 2)2 + (y - 1)2=5
(x + 2)2+(y - 1)2 = 25
(X - 1)2 + (y + 2)2=5
Answers
Answer:
(x + 2)^2 + (y - 1)^2 = 25.
Step-by-step explanation:
The centre is at (-2, 1) so the equation is:
(x + 2)^2 + (y - 1)^2 = r^2 where r is the radius.
The radius is the distance from the centre to the point (-5, -3).
Using the distance formula:
r = √ [(-3- 1)^2 + (-5 - -2)^2]
and r^2 = (-3- 1)^2 + (-5 - -2)^2
= (-4)^2 + (-3)^2
= 16 + 9
= 25.

Identify the variables in the survey. Classify each variable as numerical or categorical. For each numerical variable, identify whether it is continuous or discrete. For each categorical variable, identify whether it is nominal or ordinal.
Answers
Answers:
Gender = categorical, nominal variable
Sleep length = numerical, continuous
Bedtime = categorical, ordinal
Number of countries visited = numerical, discrete
Scale of dreading semester = categorical, ordinal
=========================
Explanation:
Gender is categorical because there are two categories or labels, male or female. It is nominal because we simply attach names to each label and we can't sort them or order them from highest to lowest. There is no ranking for gender.
Sleep length is numerical as it deals with numbers. I put continuous because someone could write 2.5 hours or 3.75 hours. If whole numbers are only allowed, then the variable would be discrete.
The bedtime portion is categorical as each time slot is a category. Like with the first part, they are simply labels. We can order them however from earliest to later on, which is why this variable is ordinal.
The number of countries visited is numeric as expected, and it's also discrete because we can't visit 0.1 of a country. By "visit", I mean step foot in any part of the country for any length of time. It does not mean you have to explore every square inch of the territory.
The last part is categorical and ordinal. The scale ranking is ordered for us from 1 to 5. Despite the fact we have numbers here, the data is not numerical as the numbers 1 through 5 represent labels of "very little" through "a lot".

What is the midpoint of a segment
with the endpoints shown to the
left?
(-18, 0)
(-9, 2)
(19,16)
(-9,0)

Answers
Answer:
(-9, 0)
Step-by-step explanation:
To find the midpoint of the segment, we use the mathematical formula below;
(x,y) = {(x1+x2)/2 , (y1+y2)/2}
From the question;
(x1,y1) = (10,16)
(x2,y2) = (-28,-16)
Substituting these values into the equation we wrote above, we have;
(x,y) = (10-28)/2 , (16-16)/2
(x,y) = (-18/2, 0/2) = (-9,0)
There are d black and brown horses in a field. There are 16 more black horses than brown horses. Of the horses in the field, only 25% of them are brown. How many are black?
Answers
Answer: 24 black horses
Step-by-step explanation:
Let the number of black horses = bl and
The number of Brown horses = br
Total number of horses = d
Of the horses in the field, only 25% of them are brown. That is,
25% of d = br
0.25d = br ........ (1)
The remaining horses are black. Which will be 100% - 25% = 75%. That is,
75% of d = bl
0.75d = bl ........(2)
But according to the question, there are 16 more black horses than brown horses. That is,
bl = br + 16 ..... (3)
The total number of horses d will be
d = br + bl ...... (4)
Substitute bl in equation 3 into equation 4
d = br + br + 16
d = 2br + 16 ..... (5)
Substitutes equation (1) into the equation (5)
d = 2( 0.25d ) + 16
d = 0.5d + 16
Collect the like terms
d - 0.5d = 16
0.5d = 16
d = 16/0.5
d = 32
Substitute 32 for d in equation (2).
bl = 0.75 × 32
bl = 24 horses.
Therefore, 24 horses are black.

Answer:
B. 40
Step-by-step explanation:
She starts with 46 and sells half of them
That leaves her with 23 stamps left.
She then buys 17 more, 23 + 17 is 40
Answer is B
Answer:
B. 40 stamps
Step-by-step explanation:
We know that she sold half of her stamps. She started with 46 stamps.
First, find 1/2 of 46.
Multiply 1/2 and 46, or divide 46 by 2.
1/2 *46= 23
46/2=23
She sold 23 stamps, and was left with 23 stamps.
Then, she bought 17 more. If she bought more, she added to the amount she already had.
Therefore, we can add 23 and 17.
23+17=40
She has 40 stamps now.

Answers
Answer:
y = 13
Step-by-step explanation:
Step 1: Distribute
3/2y - 3/2 = y + 5
Step 2: Subtract y on both sides
1/2y - 3/2 = 5
Step 3: add 3/2 on both sides
1/2y = 13/2
Step 4: Divide both sides by 1/2
y = 13
Answer:
y = 13.
Step-by-step explanation:
3/2(y-1) = y+5
3/2y - 3/2 = y + 5
3/2y - y = 5 + 3/2
1/2y = 6 and 1/2; 6.5; 13/2
y = 13.
To check out work...
3/2(13 - 1) = 13 + 5
3/2(12) = 18
3 * 6 = 18
18 = 18
On a number line, all you need to do is plot a point where it says 13. On a cartesian plane, you would have a horizontal line that expands infinitely in each direction, where y = 13.
Hope this helps!
