6. x=100
7.x=75
8.x=30
10.x=112
11.x=58 y=58
Answer:
6) x = 70°
7) x = 75°
8) x = 30°
10) x = 112°
11) x = 58° , y = 58°
Step-by-step explanation:
6) two congruent sides means two congruent angles
x + x + 40 = 180 2x = 140
7) two congruent sides means two congruent angles
both base angles measure 75 degrees
8) isosceles triangle (has two equal sides) 75(2) + x = 180 150 + x = 180
10) two congruent angles means two congruent sides
44 + 2n = 180 2n = 136 n = 68
angles n and x form a linear pair and equal 180
180 - 68 = 112
11) isosceles triangle so ∡x = ∡y 64 + x + x = 180
64 + 2x = 180 2x = 116 x = 58
Elizabeth practices the piano 1470 minutes in 5 weeks. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context.
Using proportions, it is found that the proportional equation for t in terms of d that matches the context is:
[tex]t = 42d[/tex]
Elizabeth practices the piano 1470 minutes in 5 weeks, hence, each day, consdering a week has 7 days, the amount of time she practices is:
[tex]a = \frac{1470}{35} = 42[/tex]
Hence, the proportional equation, considering t the time in minutes and d the number of days, is:
[tex]t = 42d[/tex]

One side of a triangle is 3 times the second side. The third side is 17 feet longer than the second side. The perimeter of a
triangle is 52 feet. Find the length of each side.
Provide your answer below:
Answer:
Step-by-step explanation:
lets have one side =a
P=3a+a+(17+a)=52
P=5a+17=52
5a=52-17
5a=35
a=7
second side=21
third side=24
Can someone help me find x ?
Answer:
x = 15
Step-by-step explanation:
Apply the keg rule to find x. The keg rule is given as:
Hypotenuse / leg = leg / part of the hypotenuse directly under the leg
Hypotenuse = 25
Leg = x
Part of the hypotenuse directly under the leg = 25 - 16 = 9
Plug in the values
25/x = x/9
Cross multiply
x*x = 25*9
x² = 225
x = √225
x = 15

Answer: The slope of the line is [tex]\frac{3}{4}.[/tex]
Step-by-step explanation: I use the slope formula to find the slope of the line given the graph image below that looks like this:[tex]\frac{Rise}{Run}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}.[/tex]
The rise of the points is 3 points and the run of the points is 4 points.
Now I can put it in another slope formula that looks like this: [tex]\frac{3-0}{2-(-2)}=\frac{3}{4}.[/tex]

A water tank is 90 m long and 60 m wide. What is the
volume of the water in the tank if the depth of water is
40 m?
What’s the answer ??
Answer:
216000 m^3
Step-by-step explanation:
Volume of water
= length of tank x width of tank x depth of water
= 90(60)(40) m^3
= 216000 m^3
A phone company charges for service according to the formula: C ( n ) = 29 + 0.04 n , where n is the number of minutes talked, and C is the monthly charge, in dollars. The slope in this equation is: ____________
The vertical intercept in this equation is: _____________
Hello!
Answer:Slope = 0.004
Vertical Intercept = 29.
Explanation:Basically, you can rearrange this equation so that is in the form of y = mx + b.
y = mx + b
C(n) = 0.04n + 29
The slope represents the rate of change of the cost per minute talked, and the 29 (vertical intercept) represents the monthly fee. The monthly fee will stay the same, however, the number of minutes talked is susceptible to change, hence the variable n represents it.

Is this graph and example of a sin or cos graph?
Answer:
Sine
I think
Step-by-step explanation:
The graph of the cosine is the darker curve; note how it's shifted to the left of the sine curve. The graphs of y = sin x and y = cos x on the same axes. . .. You probably noticed that these cofunction identities all use the difference of angles, but the slide of the sine function to the left was a sum.
The sine of the angle = the length of the opposite side. the length of the hypotenuse.
The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
The tangent of the angle = the length of the opposite side. the length of the adjacent side.
Translate the verbal expression: Six times a number yields 48.
six times eight equals fourtyeight

Step-by-step explanation:
Many states assess the skills of their students in various grades. One of the tests provided by a national association assesses the reading skills of 12th-grade students. In a recent year, the national mean score was 286 and the standard deviation was 38. Assuming that these scores are approximately Normally distributed, N(286, 38), use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.
Answer:
95% of these scores are between 210 and 362.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 286, Standard deviation = 38
Use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.
This is within 2 standard deviations of the mean. So
286 - 2*38 = 286 - 76 = 210
286 + 2*38 = 286 + 76 = 362
95% of these scores are between 210 and 362.

Find the area of the shaded region.
Answer:
42.14
Step-by-step explanation:
First find the area of the square:
14x14=196
Then find the area of the circle:
It has a diameter of 14 so divide it by 2 to get the radius.
Then use the formula πr²
7²=49
49x3.14=153.86
Then subtract
196-153.86=42.14

Determine if the situation is additive or multiplicative AND determine the equation that corresponds to the situation.
Equation:
Additive or Multiplicative:
Answer:
The situation is Multiplicative.
The equation will be [tex]y=2x[/tex]
Step-by-step explanation:
We are given the table:
Input (x) 5 8 11
Output (y) 10 16 22
Looking at the table, we see that the value of x is doubled to get value of y
Looking at the trend: 5(2) = 10
8(2) = 16
11(2) = 22
The value of x is multiplies by 2 to get value of y.
So, The situation is Multiplicative.
Now, The equation will be [tex]y=2x[/tex]
because we saw the trend, that every value of x is multiplied by 2 to get value of y.
