Answer:
x=18
Step-by-step explanation:
Let look at the triangle. Look at side JUI. Notices how it says JU is congruent to UI. By this definition, U must be the midpoint of J and I. The same applies for line JTK. T is the midpoint of J and K. Since J is the vertex of the triangle between K and I. Triangle JUT is the midsegment of triangle KJI. Using the triangle midsegment theorem, UT is parallel to KI Also. The theorem also states that UT is half the length of KI Also.
This is the theorem,
The Midsegment Theorem states that the segment connecting the midpoints of two sides of a triangle is parallel to the third side and half as long
So the equation is
[tex]2(3x - 43) = 4 + x[/tex]
[tex]6x - 86 = 4 + x[/tex]
[tex]5x - 86 = 4[/tex]
[tex]5x = 90[/tex]
[tex]x = 18[/tex]

I need help on 7 and 8!!!!!Find the diameter of each circle. Use a calculator’s value of Pi. Round your answer to the nearest tenth.
Answers
Answer:
37.6 in
48.2 yd
Step-by-step explanation:
The are of a circle is given as :
Area = pi(d²) /4
Area = 1110.4in²
1110.4 = 3. 14 * d² / 4
1110.4 * 4 = 3.14 * d²
4441.6 = 3.14d²
d² = 4441.6 /3.14
d² = 1413.8051
d = 37.600
d = 37.6
8.)
Area, A = 1824.7yd²
1824.7 = 3. 14 * d² / 4
1824.7 * 4 = 3.14d²
7298.8 = 3.14d²
d² = 7298.8 / 3.14
d² = 2323.2801
d = sqrt(2323.2801)
d = 48.200
Hence, diameter = 48.2 yd

Answers
Answer:
with the square inside: 708 ft
without the square: 628 ft
Step-by-step explanation:
perimeter of a semicirlce = [tex]\frac{1}{2}[/tex] (π[tex]r^{2}[/tex])
perimeter of a square = 4a
Perimeter of square: 4a
substitute 20 for a
⇒ 4a
⇒ 4 x 20
⇒ 80 ft
Perimeter of semicircle: [tex]\frac{1}{2}[/tex] (π[tex]r^{2}[/tex])
r = half of 20 which is 10
⇒ [tex]\frac{1}{2}[/tex] (π[tex]r^{2}[/tex])
⇒ [tex]\frac{1}{2}[/tex] (3.14 x [tex]10^{2}[/tex])
⇒ [tex]\frac{1}{2}[/tex] (3.14 x 100)
⇒ [tex]\frac{1}{2}[/tex] x 314
⇒ 157 ft
Since there are 4 semicirlces, just take 157 ft and multiply it by 4
⇒ 157 x 4
⇒ 628 ft
take 628 ft and add 80 ft:
⇒ 628 + 80
⇒708 ft

The base of a parallelogram is 21 yards. Find the height if the area of the parallelogram is 525 square
Answers
Answer:
25 yards
Step-by-step explanation:
A parallelogram is a quadrilateral (a four sided object) with parallel sides
Some of the characteristics of a parallelogram includes :
Opposite sides and angles are congruent . Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). The diagonals bisect each otherArea of a parallelogram = base x height
Area = 525
base = 21 yards
height = ?
525 = 21 x height
divide both sides of the equation by 21 to find the value of the height
525 / 21 = height
height = 25 yards

Need help with this question; What is the measure of one leg of a right angle given that the hypotenuse measure 14cm and the other leg measure 8cm? Please help with explanation. I'll mark you as brainiest.
Answers
Answer:
11.5 cm
Step-by-step explanation:
The dimensions of a right angled triangle can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
a² + 8² = 14²
a² + 64 = 196
a² = 196 - 64
a² = 132
find the square root of 132
a = 11.5 cm

If Rahul walks 9km in a week and Vansh walks 900 m daily, which of these is true about the distances they cover in a week?
Answers
Answer: Rahul walks 2.7 km more than Vansh.
Step-by-step explanation:
The options include:
a. Vansh walks 7.2 km more than Rahul.
b. Vansh walks 2 km more than Rahul.
c. Rahul and Vansh both cover the same distance.
d. Rahul walks 2.7 km more than Vansh.
Distance covered by Rahul weekly = 9km
Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km
From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.
Note: 1000 meters = 1 kilometers
What is the slope of a line that is perpendicular to the line that passes through the points (9,0) and (3,7)?
Answers
Answer:
6/7
Step-by-step explanation:
so, here's the thing ,the product of the slopes of perpendicular lines when multiplied must be equal to -1. So in this situation ,first find the slope of the line that passes through the given points like this :
m = y2 - y1 / x2- x1 (formula for the slope)
m= 7 - 0 / 3- 9
m=7 /-6
now you can find the perpendicular slope like this
m1 * m2= -1. (m1 = 7/-6)
7/-6 *m2=-1
m2 = 6/7

So the total cost for apples is 0.80 × a = 0.80a
And the total cost for bananas are 0.95 × b = 0.95b
Altogether, the amount will be: 0.80a + 0.95b
