A contruction company is working on a road which is 1/4 mile long. The workers divide the road into 3 equal sections. Brent claims that each section of road is 3/4 mile long.
Answer: Brent would be wrong because each section of the road is 1/12 mile long
Step-by-step explanation:
The road is 1/4 mile long. When divided into 3 equal parts, it is done in the following manner:
= 1/4 ÷ 3
= 1/4 * 1/3
= 1/12
Each section of the road is 1/12 of a mile long.
3/4 is actually a larger quantity than 1/4 so saying that each section was 3/4 of a mile would mean it was longer than the road itself which is not logical.
Solve 5(5x - 3) = 10
Answer:
x=1
Step-by-step explanation:
hope this helps :)
Answer for : 5 (5x - 3) = 10
1. Opening the brackets:
25x - 15 = 10
2. Taking all known numbers to the other side:
25x = 10 + 15 (taking a number over means you have to change the sign)
3. Solving the known side:
25x = 25
4. Isolating the Variable:
x = 25/25
5. Solving the equation:
x = 1

Help? It says find the surface area of the triangular prism, and the base is an isosceles triangle
Given:
The figure and dimensions of the triangular prism.
The base is an isosceles triangle
To find:
The area of the triangular prism.
Solution:
The area of a triangle is:
[tex]A_1=\dfrac{1}{2}\times base\times height[/tex]
The base of the triangle is 24 cm and the height is 35 cm. So, the area of a triangular base (in sq. cm) is:
[tex]A_1=\dfrac{1}{2}\times 24\times 35[/tex]
[tex]A_1=12\times 35[/tex]
[tex]A_1=420[/tex]
The bases of the triangular prism are same. So, the area of the other triangular base is [tex]A_2=420[/tex] sq. cm.
The sides of the base triangle are 37 cm, 37 cm and 24 cm. So, the perimeter of the base triangle is:
[tex]P=37+37+24[/tex]
[tex]P=98[/tex]
Now, the curved surface area of the prism is:
[tex]A_3=P\times h[/tex]
Where, P is the base perimeter and h is the height of the prism.
The base perimeter of the triangular prism is 98 cm and the height is 48 cm. So, the curved surface area is:
[tex]A_3=98\times 48[/tex]
[tex]A_3=4704[/tex]
Now, the total area of the triangular prism is:
[tex]A=A_1+A_2+A_3[/tex]
[tex]A=420+420+4704[/tex]
[tex]A=5544[/tex]
Therefore, the area of the given triangular prism is 5544 sq. cm.
Someone help me ASAP please and thank you

Step-by-step explanation:
It's exactly what's asked for.
Find the area of the triangle
A)
B)
09
11 ft2
D)
224²
Answer:
A
Step-by-step explanation:
Area of a triangle = [tex]\frac{bh}{2}[/tex]
where b = base length and h = height
the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5
So area =
[tex]\frac{2\frac{1}{2} *4\frac{2}{5} }{2} \\\\2\frac{1}{2} *4\frac{2}{5} =11\\\\\frac{11}{2} =5.5[/tex]
5.5 also = [tex]5\frac{1}{2}[/tex]
Hence, the correct answer is A
2x + 4y = 16
3x - 2y = 8
solve using SUBSTITUTION METHOD ONLY!
PLS ANSWER QUICK !!!
Answer:
x = 4, y = 2
Step-by-step explanation:
3x - 2y = 8
-2y = -3x + 8
y = 3/2x - 4
2x + 4(3/2x - 4) = 16
2x + 6x - 16 = 16
8x = 32
x = 4
3(4) - 2y = 8
12 - 2y = 8
-2y = -4
y = 2

We can use the Pythagorean Theorem to solve the triangle for x.
[tex]25^2=14^2+x^2[/tex]
[tex]625=196+x^2[/tex]
[tex]x^2=429[/tex]
[tex]x=\sqrt{429}[/tex]
x≈20.7
Find Side BC and round to the nearest tenth of a decimal
Answer:
17.0
Step-by-step explanation:
If you take the sin(39) or cos(51), it is equal to BC/27. Multiply by 27 on both sides to get 27cos(51) or 27sin(39)= x. Plug into the calculator, and voila.
Rewrite in vertex form y=x2+2x+6
Answer:
y = (x+1)^2+5
Step-by-step explanation:
Add or subtract from both sides to complete the square;
y=x^2+2x+6; Subtract 5 from both sides
y-5 = x^2+2x+1; Factor;
y - 5 = (x+1)^2; Add 5 back to both sides;
y = (x+1)^2+5
Answer:
y=(x+1)²+5
Step-by-step explanation:
y=x^2+2x+6
a=1; b=2;c=6
subtract 6 from both sides: x^2+2x= -6
complete the square by using the equation (b/2)^2 and add to both sides: x^2+2x+1=-6+1
simplify: x^2+2x+1=-5
find the factors of 1 that add up to 2: 1 and 1
(x+1)(x+1)=-5
add 5 to both sides and simplify
y=(x+1)^2+5

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answer:
40 waves
Step-by-step explanation:
Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%
Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40
Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.Find the measure of the indicated angle to the nearest degree.

David is the coach of the Bingtown Cougars hockey team. There are 2 minutes left in the game they are playing and they are currently losing by 1 point. In the past, when losing by 1 point, he has pulled the goalie out of the game and replaced the goalie with a forward player a total of 21 times. When in the same position, he has left the goalie in the game 14 times. In the situations when he has pulled the goalie, they have lost 7 times, tied 8 times, and won 6 times. In the situations when he has left the goalie in the game, they have lost 8 times, tied 2 times, and won 4 times. Based on these numbers, if the goal is to either tie or win the game, should he pull the goalie or not? O A. David should pull his goalie. OB. David should not pull his goalie. OC. There is not enough information to determine if he should pull his goalie or not. OD Neither option has any advantage.

Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let the total number of students in the class= x
No. of students who passed the test = 18 = 72% of x = 72x/100
Therefore, 72x/100=18
=72x=18*100=1800
=x=1800/72= 25 students.
Hence, total number of students in the class= 25 students

Which system of equations has infinitely many solutions?
A
4x+2y=8
4x−2y=8
B
4x−2y=8
−4x+2y=−8
C
4x+2y=8
4x+2y=10
D
4x+2y=8
−4x−2y=−10
Answer: B.
[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]
Step-by-step explanation:
Let's solve your system by elimination.
4x−2y=8;−2x+2y=6
Add these equations to eliminate y:
4x-2y=8
-2x+2y=6
2x=14
Substitute 7 for x in 4x−2y=8:
(4)(7)−2y=8
−2y+28=8 (Simplify both sides of the equation)
−2y+28+−28=8+−28 (Add -28 to both sides)
−2y=−20
−2y/−2=−20/−2 (Divide both sides by -2)
y=10
