!!!Quick!!! Barbara can walk 3200 meters in 24 minutes. How far can she walk in 3 minutes? (In Meters)
Answer:
400 meters
Step-by-step explanation:
First, divide 3,200 by 24 to find the rate, which is 133.3 (repeated).
Now, multiply 133.3 by 3, which is your answer! 133.3*3=399.9. 399.9 is extremely close to 400, so we can just round it to that.

ZA and ZB are vertical angles. If m_A = (4x – 13)° and m
ZB = (3x + 19)', then find the measure of ZA.
Answer:
115 degrees
Step-by-step explanation:
Vertical angles are congruent by the vertical angles theorem.
Hence,
<A=<B
4x-13=3x+19
x=32
Substituting 32 in for x in <A
4(32)-13= 115
What value of x makes the equation 3(x – 6) – 8x = –2 + 5(2x + 1) true? Explain your answer
Answer:
x = -7/5
Step-by-step explanation:
3( x - 6 ) - 8x = -2 + 5(2x + 1)
3x - 18 - 8x = -2 + 10x + 5
-5x - 18 = 3 + 10x
-5x - 10x = 3 + 18
-15x = 21
x = [tex]-\frac{7}{5}[/tex]

Can 10, 11, 2 be measures of the sides of a triangle
Answer:
Yes
Step-by-step explanation:
The Triangle Inequality Theorem says the sum of any two side lengths of a triangle has to be greater than the third side.
With the measures of 10, 11, and 2, this follows the theorem.
For example, 10 + 11 is 21, which is greater than 2.
11 + 2 is 13, which is greater than 10.
This works for all the combinations, so 10, 11, and 2 can be the side lengths.

solve the equation 4x^2-27x-5=-10x to the nearest tenth
Answer:10x^2-27x+5. 10x2−27x+5 10 x 2 - 27 x + 5. For a polynomial of the form ax2+bx+c a x 2 + b x + c , rewrite ...
Step-by-step explanation:
The solution of the equation:
x = -0.28 to the nearest tenth.
x = 4.53 to the nearest tenth.
What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
A quadratic equation,
4x²-27x-5 = -10x
Simplifying,
4x²-27x-5 + 10x = 0
4x²-17x-5 = 0
So,
x = {-(-17) ± √(289 + 80)}/8
x = (17 ± √369) / 8
When we take - sign,
x = - 0.276
x = -0.28 to the nearest tenth.
When we take + sign,
x = 4.526
x = 4.53 to the nearest tenth.
Therefore, the values are x = -0.28 and x = 4.53.

A study found that the average time a person spent exercising each week was 84 minutes, but there could be up to a 3% error in this
number. Which of these could be the actual average time spent?
es
A)
78.32 minutes
B)
81.48 minutes
C)
87.32 minutes
D)
88.64 minutes
B is the answer
Answer:
C
Step-by-step explanation:
The actual average time = 81.5 minutes
The correct answer is an option (B) 81.48 minutes
What is percent error?"percent error = [(estimated value - actual value) / (actual value)] × 100"
For given example,
percent error (e) = 3%
estimated average time spent (x) = 84 minutes
We need to find the actual average time spent (y)
Using the formula of percent error,
⇒ e = [(x - y)/y] × 100
⇒ 3 = (84 - y)/y × 100
⇒ (84 - y)/y = 3/100
⇒ (84 - y) / y = 0.03
⇒ 84 - y = 0.03y
⇒ 84 = 0.03y + y
⇒ 84 = (1.03)y
⇒ y = 81.5 minutes
Therefore, the actual average time = 81.5 minutes
The correct answer is an option (B) 81.48 minutes
