if the perimeter of Triangle XYZ is 56 cm, what is the perimeter of Triangle ABC?
Answer:
28 cm
Step-by-step explanation:
Triangle ABC is obtained by joining the mid points of the sides of triangle XYZ.
So, perimeter of triangle ABC will be equal to half of the perimeter of triangle XYZ.
[tex] P(\triangle ABC) = \frac{1}{2} \times P(\triangle XYZ) [/tex]
[tex] P(\triangle ABC) = \frac{1}{2} \times 56 [/tex]
[tex] P(\triangle ABC) = 28\: cm [/tex]

A object falls at 16t^2 feet in t seconds you drop a rock from a bridge that is 906 what is the hight in feet after the rock is droped
Answer:
824 feet
Step-by-step explanation:
Given
[tex]h(t) = 16t^2[/tex]
[tex]H = 906[/tex] -- Initial Height
Required
Calculate the height after 2 seconds --- missing from the question
First, we calculate the distance moved in 2 seconds
[tex]h(t) = 16t^2[/tex]
[tex]h(2) = 16*2^2[/tex]
[tex]h(2) = 16*4[/tex]
[tex]h(2) = 64[/tex]
This means that the object covered 64feet
The object current height is then calculated as:
[tex]Height = H - h(t)[/tex]
t = 2. So, the equation becomes
[tex]Height = H - h(2)[/tex]
Substitute values for H and h(2)
[tex]Height = 906- 64[/tex]
[tex]Height = 824[/tex]

Grace made a dot plot showing the distances she ran each day for two weeks.
She says that she usually runs 7 miles each day because that is the distance that occurs most often.
Do you agree with Grace’s reasoning?
Use the drop-down menus to explain and show your answer.
Dot plot named as ALTDCDistances RunALTDC has number line from 1 to 7. 1 dot on 1, 3 dots on 2, 3 dots on 3, 3 dots on 4 and 4 dots on 7 are given.
The mode, which is (3,4, or 7) ,(is or is not) a typical distance for the data. The median, which is (3.5,4, or 7),(is or is not) a typical distance for the data. The mean, which is (3,4, or 7) ,(is or is not) a typical distance for the data. So, Grace’s reasoning(is or is not ) correct.
Answer:
The mode, which is 7, is not a typical distance for the data. The median, which is 3.5, is not a typical distance for the data. The mean, which is 4, is a typical distance for the data. So, Grace’s reasoning is not correct.

b. Solve the inequality.
In Fluorescent higher secondary school there are 53 students in class 8. If number of boys is 3 morethan that of number of girls find.
a. Equation representing the number os students.
b. The number of Boys and Girls.
Answer:
a. 3g + g = 53
b. 40 boys and 13 girls
Step-by-step Explanation:
(3g = number of boys)
(g = number of girls)
3g + g =53
4g = 53
g = 13.2
53 - 13.2 = 39.8 (boys)
we round to the nearest tenth on both
girls 13.2---13
boys 39.8---40

1- The area of a parallelogram is 507 cm2. Its height is six times its base. Find the height and base.
Answer:
507=b x (3 x b)
507=b x 3b
507=3b^2
b^2=507/3
b^2=169
b=13
h=3 x b
h=3 x 13
h=39
Step-by-step explanation:
The height and base of the parallelogram is b = 13 cm and h = 78 cm
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The sum of angles of a parallelogram is 360°
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the area of the parallelogram be represented as A
Now , the value of A = b x h
where the base of the parallelogram is b
The height of the parallelogram is h
So , 507 = b x h
And , height is three times its base
So , h = ( b x 3 )
On simplifying , we get
507 = b ( b x 3 )
507 = 3b²
Divide by 3 on both sides , we get
b² = 169
Taking square roots on both sides , we get
b = 13 cm
So , the height of the parallelogram is h = 78 cm
Hence , the parallelogram is solved

write a quadratic equation with the roots 1/2 and -5
x = 1/2 or x = -5
2x - 1 = 0 or x + 5 = 0
(2x-1)(x+5) = 0
2x² + 10x - x - 5 = 0
2x² + 9x - 5 = 0
Hope it helps!
Answer:
2[tex]x^{2}[/tex] + 9x - 5 = 0
Step-by-step explanation:
// Use the Vijet's theorem,
// note that the kofficient before [tex]x^{2}[/tex] = 1
Sum of the roots is:
1/2 + (-5) = - 4,5
Product of the roots is:
0,5 * (-5) = - 2,5
Formation of quadratic equation:
[tex]x^{2}[/tex] - (sum of the roots) x + product of the roots = 0
[tex]x^{2}[/tex] - (-4,5) * x + (-2,5) = 0
[tex]x^{2}[/tex] + 4,5x -2,5 = 0
// multiply both sides by 2
2[tex]x^{2}[/tex] + 9x - 5 = 0

How many liters of 30% salt solution must be added to 6 L of an 80% salt solution to obtain a 50% salt solution
Answer:
9 Liters
Step-by-step explanation:
Let us represent:
The number of liters of the 30% salt solution = x
Number of liters for the 80% solution = 6 Liters
Number of liters for the 50% solution = x + 6 Liters
Hence:
x × 30% + 6 × 80% = (x + 6)50%
0.3x + 4.8 = 0.5x + 3
Collect like terms
4.8 - 3 = 0.5x - 0.3x
1.8 = 0.2x
x = 1.8/0.2
x = 9 Liters
Therefore, the number of liters for the 30% Salt solution = 9 Liters
