AREA OF TRIANGLE BASE=7 and 4
Answer:
area: 14
Step-by-step explanation:
find yz 11x+1 and 19x-31
The length of a segment is the number of units between its endpoints
The length of YZ is 45 units
How to determine length YZThe given parameters are:
WX = 11x + 1
YZ = 19x - 31
Lengths WX and YZ are congruent.
So, we have:
[tex]19x - 31 = 11x +1[/tex]
Collect like terms
[tex]19x - 11x = 31 +1[/tex]
Evaluate the like terms
[tex]8x = 32[/tex]
Divide both sides by 32
[tex]x = 4[/tex]
Recall that:
YZ = 19x - 31
So, we have:
[tex]YZ = 19*4- 31[/tex]
[tex]YZ = 45[/tex]
Hence, the length of YZ is 45 units

AB is congruent to DE because segment DE was constructed so that DE = AB. BC is congruent to EF because segment EF was constructed so that EF = BC. Since ADEF is a right triangle, DE+ EF? = DF? by the We are given that AB + BC2 = AC? Since DE = AB and EF = BC, DE2 + EF2 = AC? by the Also, DF2 = AC2 by the Taking the square root of both sides of the equation gives DF = AC. So, AC is congruent to DF by the definition of congruence. Applying the AABC - ADEF. By CPCTC, ZB _ZE. Therefore ZB is a right angle and AABC is a right triangle.
DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.
Congruent shapeTwo shapes are said to be congruent if they have the same shape, all their corresponding angles and sides are congruent to one another.
Given that DE = AB and BC = EF.
In right triangle DEF, using Pythagoras:
DF² = DE² + EF²
Also, In right triangle ABC, using Pythagoras:
AC² = AB² + BC²
But DE = AB and EF = BC, hence:
AC² = DE² + EF²
AC² = DF²
Taking square root of both sides, hence:
AC = DF
Since DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.

The point V(4, –1) is rotated 90° clockwise around the origin. What are the coordinates of its image V’? V’(1, 4) V’(–1, 4) V’(–1, –4) V’(4, 1)
Answer:
V' = (-1, -4)
Step-by-step explanation:
the original point V (4, -1) is 4 units to the right and 1 unit down.
now we turn this 90° clockwise (upper right to down to upper left).
that means the right part of the x-axis turns into the bottom part of the y-axis, and the bottom part of the y-axis into the left part of the x-axis.
so, positive x turns into negative y, and the negative y turns into negative x.
therefore, (4 -1) turns into (-1, -4).
Answer:
C V'(-1,-4)

the radius of a circle is 7 cm .the circle is divided into two equal parts .what is the perimeter of the semi circular part
Answer:
P = 35.98 cm
Step-by-step explanation:
The Perimeter of a shape is the distance around the outside of it. This semi-circle (half circle) has a straight part and the curved part. See image. The straight part is the diameter (distance through the center) it is double the radius that was given, 7 cm.
The circumference of a circle is the perimeter of the whole circle.
C = 2pi•r or pi•d
C = 2pi•7 = 14pi
But you only need half, so 14pi/2 is 7pi.
ADD the straight part and the curved part to get the whole distance around the shape
P = 14 + 7pi
P ~= 35.98 cm
See image

One angle of a parallelogram measures 162°. What are the measures of the other three angles in the parallelogram?
Answer:
The important properties of parallelograms to know are:
-Opposite sides of parallelogram are equal (AB = DC).
-Opposite angles of parallelogram are equal (D = B).
-Consecutive angles in a parallelogram are supplementary (A + D = 180°).
-If one angle is 90 degrees, then all other angles are also 90 degrees.
FROM
SURAJ SAINI
Answer:
162,162,18,18
Step-by-step explanation:
each two opposite angles are equal
since there is an angle equals 162° then the opposite angle equals 162°
since the sum of all angles equal 360°
360-(162+162)= 36
so the sum of the other two opposite angle = 36 then the measure of one angle =36/2 =18°

Anita can iron a dress shirt in 15 minutes, but
it takes Michelle 18 minutes to do the same.
Working together, how many minutes will it take
them to iron 11 dress shirts?
The number of minutes it will take both of them to iron 11 dress shirt is 90 minutes
Rate:
Rate is the ratio between two related quantities in different units. Therefore,
Anita iron a shirt in 15 minutes. Therefore,
rate = 1 / 15Michelle iron the same shirt for 18 minutes. Therefore,
rate = 1 / 18Let the time they use to work together = x
Therefore,
1 / x = 1 / 15 + 1 / 181 / x = 18 + 15 / 270
1 / x = 33 / 270
cross multiply
270 = 33x
x = 270 / 33
x = 90 / 11
Both of them will use 90 / 11 minutes to iron a dress shirt
Therefore, 11 dress shirt will be ?
number of minutes to iron 11 dress shirt together = 11 × 90 / 11 = 90 minutes

It can be deduced that the sample space is the collection of the set of possible outcomes in a random experiment.
What is a sample space?Your information is incomplete as the graphs aren't provided. Therefore, an overview of the sample space will be given.
A sample space simply means the collection of the set of possible outcomes in a random experiment.
It should be noted that a sample space is usually represented by the symbol S.
Also, the theoretical probability distribution states that the probability of occurence of an event will be equal to the number of the favorable outcomes divided by the total outcomes possible.

Lily threw a ball. The balls equation that demonstrated its height and velocity is:
h(x) = -16x2 + 3x + 35
What was the initial height that she threw the ball from?
The initial height of the ball is the y-intercept of the function
The initial height she threw the ball from is 35
How to determine the initial heightThe function is given as:
[tex]h(x) = -16x^2 + 3x +35[/tex]
Set x = 0.
So, we have:
[tex]h(0) = -16 * 0^2 + 3*0 +35[/tex]
Evaluate the exponent
[tex]h(0) = -16 * 0 + 3 * 0 + 35[/tex]
Evaluate the products
[tex]h(0) = 0 + 0 + 35[/tex]
Evaluate the sum
[tex]h(0)= 35[/tex]
