In the adjoining figure, find the values of X and Y.
Answer:
x=5 cm,y=12 cm
Step-by-step explanation:
We are given that
RQ=3 m
PQ=4 cm
RP=x cm
RS=13 cm
SP=y cm
We know that Pythagoras theorem
[tex](Hypotenuse)^3=(base)^2+(perpendicular\;side)^2[/tex]
In right triangle RQP
Using Pythagoras theorem
[tex]RP^2=RQ^2+PQ^2[/tex]
Substitute the values
[tex]x^2=3^2+4^2[/tex]
[tex]x^2=9+16[/tex]
[tex]x^2=25[/tex]
[tex]x=\sqrt{25}=5[/tex]cm
Now,
In triangle RPS
[tex]RS^2=RP^2+SP^2[/tex]
[tex](13)^2=5^2+y^2[/tex]
[tex]169=25+y^2[/tex]
[tex]169-25=y^2[/tex]
[tex]144=y^2[/tex]
[tex]y=\sqrt{144}=12[/tex] cm

What is the measure of _Y, in degrees?
y
A. 116°
B. 32°
C. 640
D. Cannot be determined
Answer:
C. 116º
Step-by-step explanation:
Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.
32 + 32 = 64
180 - 64 = 116
Drag the symbol to complete the solution to this inequalities
Answer:
x ≤ 13.2.
Step-by-step explanation:
6 ≥ x/2.2
Multiply both sides by 2.2:
6 * 2.2 ≥ x
x ≤ 13.2.
The solution to the inequality is [tex]x \leq 13.2[/tex], the correct symbol used in blank is ≤.
To complete the solution to the inequality [tex]6 \geq \frac{x}{2.2}.[/tex]
Rearrange the inequality as follows:
[tex]\frac{x}{2.2} \le 6[/tex]
The solution to the inequality is:
[tex]x \leq 13.2[/tex]
Comparing the expression [tex]\frac{x}{2.2}[/tex] to 6, we can see that [tex]\frac{x}{2.2}[/tex] should be less than or equal to 6 in order for the inequality to hold true.
Therefore, the correct symbol to place in the blank is "≤" and solution is [tex]x \leq 13.2[/tex].

Solve and check -2x + 3 = -11
Answer:
x=7
Step-by-step explanation:
1. -2x+3=-11 << first make sure the x is one one side of the equal sign. so remove the 3, by subtracting if from 11
2. -2x+3=-11
-3 -3

Catherine bought apples and pears for a school picnic. The total number of pieces of fruit that she bought was less than 100. She bought more apples than pears.
Answer:
it says LESS THAN not less tha n or equal to so it cant be a or b or d, so it is c!
Step-by-step explanation:
Catherine bought apples and pears for the school picnic. If the total fruit is less than 100, then the correct equation for this will be y<100-x and y<x. Hence, option C is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
