The value of t is 22
Step-by-step explanation:
Let us solve the question
In any triangle
∵ The sum of the measures of the interior angles of a triangle is 180°
∵ The angle of triangles are ∠1, ∠2, and ∠3
∴ m∠1 + m∠2 + m∠3 = 180°
∵ The three angles of the triangle are 2t, 3t, and 70°
∴ m∠1 = 2t
∴ m∠2 = 3t
∴ m∠3 = 70°
→ Substitute them in the rule above
∴ 2t + 3t + 70° = 180°
→ Add the like terms
∵ (2t + 3t) + 70 = 180
∴ 5t + 70 = 180
→ Subtract 70 from both sides
∵ 5t + 70 - 70 = 180 - 70
∴ 5t = 110
→ Divide both sides by 5
∴ t = 22
∴ The value of t is 22

In a triangle, PR is 12 more than twice PQ and QR is two more than 4 times PQ. If all three sides of the triangle have integer lengths, what is the largest possible value of x?
Answers
Answer:
x = 10
Step-by-step explanation:
In a triangle, PR is 12 more than twice PQ and If all three sides of the triangle have integer lengths, what is the largest possible value of x?
From the attached diagram, x = PQ
We have sides:
PQ, PR and QR
PR is 12 more than twice PQ
PR = 12 + 2PQ
PR = 12 + 2x
QR is two more than 4 times PQ.
QR = 2 + 4(PQ)
QR = 2 + 4x
Hence: we solve using Triangle Inequality
The triangle inequality states that the sum of the lengths of two sides of a triangle must be greater than the length of the third side.
Based on this property, if you know the lengths of two sides of a triangle and are trying to find the range of lengths of the third side, you can add the two known side lengths together and subtract the smaller one from the bigger one. The third side must be greater than the sum of the other two sides and less than their difference.
PQ > PR + QR
PQ < PR - QR
Therefore:
x + 12 + 2x > 2 + 4x
3x + 12 > 2 + 4x
12 - 2 > 4x - 3x
10 = x
3. Consider the following diagram.
Find the values of m and n that prove the two triangles are congruent by the
HL Theorem.
Answers
Answer:
m = 3, n = 6
Step-by-step explanation:
The hypotenuse leg (HL) theorem states that two triangles are said to be similar if one leg and the hypotenuse of the triangles are congruent.
From the diagram, comparing the hypotenuse of the triangles;
4m + 1 = 13
4m = 13 - 1
= 12
m = [tex]\frac{12}{4}[/tex]
= 3
m = 3
Also, comparing the sides;
2m + n = 8m - 2n
substitute the value of m to have,
6 + n = 24 - 2n
collect like terms,
n + 2n = 24 - 6
3n = 18
n = [tex]\frac{18}{3}[/tex]
= 6
n = 6
m = 3, n = 6
To solve the problem we must know about HL theorem.
What is the HL theorem?According to the HL theorem, If the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent. therefore, the hypotenuse will be congruent to each other, and the corresponding sides will be congruent to each other.
The value of m and n are 3 and 6, respectively.
Given to us
The hypotenuse of the first triangle = 13One leg of the first triangle = 2m+nThe hypotenuse of the second triangle = 4m+1One leg of the second triangle = 8m - 2nAccording to the HL theoremIf the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent. therefore,
the hypotenuse will be congruent to each other, and the corresponding sides will be congruent to each other.
Hypotenuse Congruent[tex]4m + 1 =13\\\\4m=13-1\\\\m=\dfrac{12}{4}\\\\m=3[/tex]
Corresponding Congruent sides[tex]2m+n = 8m-2n\\[/tex]
Substitute the value of m,
[tex]2(3)+n = 8(3)-2n\\\\6+n = 24-2n\\\\6-24 = -2n-n\\\\-18 = -3n\\\\n=\dfrac{-18}{-3}\\\\n = 6[/tex]
Hence, the value of m and n are 3 and 6, respectively.

Point Q with coordinates (4, –7) is rotated 270° clockwise about (5, 1) . What are the coordinates of its image?
Answers
Answer:
The coordinates of the image are [tex]Q'(x,y) = (13,0)[/tex].
Step-by-step explanation:
The rotation of point Q around a given point of reference is defined by:
[tex]Q'(x,y) = O(x,y) + r_{OQ}\cdot (\cos (\theta_{OQ}\pm \theta_{R}),\sin (\theta_{OQ}\pm \theta_{R}))[/tex] (1)
Where:
[tex]O(x,y)[/tex] - Point of reference.
[tex]r_{OQ}[/tex] - Magnitude of line segment OP.
[tex]\theta_{OQ}[/tex] - Direction of the point Q with respect to the point of reference, measured in sexagesimal degrees.
[tex]\theta_{R}[/tex] - Rotation angle, measured in sexagesimal degrees.
[tex]Q'(x,y)[/tex] - Rotated point.
Please notice that positive sign means counterclockwise rotation, whereas the negative sign represents clockwise rotation.
The magnitude and direction of the line segment are defined by the following expressions:
Magnitude
[tex]r_{OQ} = \sqrt{(x_{Q}-x_{O})^{2}+(y_{Q}-y_{O})^{2}}[/tex] (2)
Direction
[tex]\theta_{OQ} = \tan^{-1}\left(\frac{y_{Q}-y_{O}}{x_{Q}-x_{O}} \right)[/tex] (4)
Where:
[tex]x_{O}[/tex], [tex]y_{O}[/tex] - Coordinates of point of reference.
[tex]x_{Q}[/tex], [tex]y_{Q}[/tex] - Coordinates of the point Q.
If we know that [tex]x_{O} = 5[/tex], [tex]y_{O} = 1[/tex], [tex]x_{Q} = 4[/tex], [tex]y_{Q} = -7[/tex], then the magnitude and direction of the segment OQ are, respectively:
[tex]r_{OQ} = \sqrt{(4-5)^{2}+(-7-1)^{2}}[/tex]
[tex]r_{OQ} \approx 8.062[/tex]
[tex]\theta_{OQ} = \tan^{-1}\left(\frac{-7-1}{4-5} \right)[/tex]
[tex]\theta_{OQ} = \tan^{-1}\left(\frac{-8}{-1} \right)[/tex] (Which means that line segment OQ belongs to third quadrant)
[tex]\theta_{OQ} \approx 262.875^{\circ}[/tex]
If we know that rotation is clockwise, [tex]x_{O} = 5[/tex], [tex]y_{O} = 1[/tex], [tex]r_{OQ} \approx 8.062[/tex] and [tex]\theta_{OQ} \approx 262.875^{\circ}[/tex], then the rotated point is:
[tex]Q'(x,y) = (5,1) + (8.062\cdot \cos (262.875^{\circ}-270^{\circ}),8.062\cdot \sin (262.875^{\circ}-270^{\circ}))[/tex]
[tex]Q'(x,y) = (5,1) + (8, -1)[/tex]
[tex]Q'(x,y) = (13, 0)[/tex]
The coordinates of the image are [tex]Q'(x,y) = (13,0)[/tex].

A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she descended 41.6 feet. How many feet had she been below sea level, if she was 102 feet below sea level after she descended?
Answers
Answer:
143.6 below sea level
Step-by-step explanation:
Given that:
Initial altitude of the submarine = 102 feet below sea level
Distance descended over the next 10 minutes = 41.6 minutes
To find:
The altitude below sea level after she descended ?
Solution:
To find the resultant altitude below sea level, we need to subtract the altitude descended in the next ten minutes from the initial altitude.
We are doing so because scientist has further descended i.e. gone below the water.
Initial altitude is also in negative sign because of the fact that it is below sea level.
Therefore, the answer can be found as:
-102 - 41.6 = - 143.6
OR
143.6 below sea level is the answer.

Answers
Answer:
[2(p + 1)]/q
Step-by-step explanation:
logx 2 = p
logx 7 = q
log7 4x² = log7 (2x)²
= (logx (2x)²)/(logx 7)
= (2 logx 2x)/(logx 7)
= (2 logx 2 + 2 logx x)/(logx 7)
= (2p + 2)/q

Answers
for billy: 2x+3y=35$

We need to get rid of one of the unknowns inorder to solve, therefore we will subtract the two equations from each other. This will get rid of the y variable(3y-3y=0)
2x+3y=35$
-
3x+3y=45$
=
-1x=-10$
we get rid of the negative, which leaves us with x=10$. Knowing this info, we can now easily calculate y:
2x+3y=35$
2(10)+3y=35$
20+3y=35$
3y=15
y=15/3
y=5

Sid has £5 to buy apples and bananas.
He uses his money like this:
He buys 18 apples.
Then he buys as many bananas as possible.
With his change he buys more apples.
How many apples and bananas does he buy?
(Apples=6p Each)
(Bananas= 40p Each)
Answers
Bananas = 9 and Apples = 22
Explanation below -
Step-by-step explanation:
cost of 18 apples= 18x6p= 108p
£5-108p= x (will let it be x since i do not know the conversion)
maximum number of banana he can buy= x divide by 40p (rounded down to smallest whole number)= b
The change he have= x-(40×b) = y
apples bought with change= y divide by 6p= a
do the working above to find value for a and b, add a to the 18 apples bought initially and b is number of banana
