Answer: 154
Step-by-step explanation:
The mean is calculated by adding up all the numbers and dividing by the number of observations added up.
The above can therefore be expressed as:
(88 + 55 + 99 + x) / 4 = 99
242 + x = 99 * 4
242 + x = 396
x = 396 - 242
x = 154
How many real number solutions does the equation y=2x^2−8x+8 have?
Answer:
1 real solution
Step-by-step explanation:
y=2x^2−8x+8
We can use the discriminant to determine the number of real solutions
b^2 -4ac
a =2 b = -8 c=8
(-8)^2 - 4(2)(8)
64 - 64
0
Since the discriminant is 0 there is 1 real solution
>0 there are 2 real solutions
< 0 two complex solutions
What is the area of the shaded portion of the circle?
9514 1404 393
Answer:
(a) (5π -11.6) ft²
Step-by-step explanation:
The shaded area is the area of 1/5 of the circle less the area of the triangle with base 5.8 ft and height 4 ft.
shaded area = 1/5(π(5 ft)²) -(1/2)(5.8 ft)(4 ft)
shaded area = (5π -11.6) ft²

The range of the function is to because 4x is always positive
The range of the function is ZERO to POSITIVE INFINITY because 4^x is always positive.
Step-by-step explanation:
The range of the function is 0 to positive infinity because [tex]4^x[/tex] is always positive.
What is the range of a functionThe range of a function is the set of output values of the function
The expression of the function is given as:
[tex]4^x[/tex]
Rewrite as:

Solve for e.
9e+4=-5e+14+13e
Answer and Step-by-step explanation:
First, write down the equation.
9e + 4 = -5e + 14 + 13e
Combine like terms.
9e + 4 = 8e + 14
Subtract 4 and 14 from both sides of the equation.
e = 10
e = 10 is the answer.

Tamika was buying 12-packs of soda. Each pack cost $3.50. If she spent $49.00, how many 12-packs did she buy?
Answer:
Number of 12-packs = 14
Step-by-step explanation:
Cost Number of 12-packs
3.50 1
49.00 x
[tex]\frac{1}{x} = \frac{3.50}{49}\\\\1 \times 49 = 3.50 \times x\\\\\frac{49}{3.50} = x\\\\x = 14[/tex]
Number of 12-packs for $49 = 14

Problem 3
Answer: 1/5 of a gallon per minute-------------------------
Explanation:
Two points from the graph are (10,2) and (20,4)
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (4-2)/(20-10)
m = 2/10
m = 1/5
The slope of the graph is 1/5.
Do the same for two points from the table. I'll use the first two rows
m = (y2-y1)/(x2-x1)
m = (4-2)/(10-5)
m = 2/5
The slope of the table is 2/5.
Subtract the two slopes to wrap things up:
2/5 - 1/5 = (2-1)/5 = 1/5

Answer: 23 degrees------------------------
Explanation:
Angles 1 and 3 are same side exterior angles, so they are supplementary due to the parallel lines set up here.
(angle1)+(angle3) = 180
(157) + (angle3) = 180
angle3 = 180-157
angle3 = 23 degrees

Given:
In triangle ABC, AB = AC, AD is angle bisector and measure of angle C is 49 degrees.
To find:
The value of x and y.
Solution:
In triangle ABC,
[tex]AB=AC[/tex] (Given)
So, triangle ABC is an isosceles triangle and by the definition of base angles the base angles of isosceles triangle are congruent.
In isosceles triangle ABC,
[tex]\angle B\cong \angle C[/tex]
[tex]m\angle B\cong m\angle C[/tex]
[tex]m\angle B\cong 49^\circ[/tex]
The angle bisector of an isosceles triangle is the median and altitude of the triangle. So, the angle bisector is perpendicular to the base.
[tex]m\angle ADB=90^\circ[/tex]
[tex]x^\circ=90^\circ[/tex]
In triangle ABD,
[tex]m\angle DAB+m\angle ABD+m\angle ADB=180^\circ[/tex] [Angle sum property]
[tex]y^\circ+49^\circ+x^\circ=180^\circ[/tex]
[tex]y^\circ+49^\circ+90^\circ=180^\circ[/tex]
[tex]y^\circ=180^\circ-49^\circ-90^\circ[/tex]
[tex]y^\circ=41^\circ[/tex]
Therefore, the correct option is B.

Answer:
x = 19
Step-by-step explanation:
x-42+x-32+180-x+17 = 180
3x +123 = 180
3x = 57
x=19
x = 91.
Putting 91 into the two equations inside the triangle makes the angles 59 and 49, and makes the outside angle 108. Those two angles must add and equal the outside angle, and they do, meaning x = 91.

7. What are the measures of ∠a, ∠b, and ∠c?
Answer:
a = 65°
(what's missing for a half turn)
c = 30°
(bc same angle as upper left)
b = 85°
(bc a+b+c must be 180° in sum, as always in triangles)
please brainliest
Answer:
a = 45
b = 105
c = 30 .
Step-by-step explanation:
a + 135 = 180 {Linear pair}
a = 180 - 135
a = 45
d = 30 {Vertically opposite angles}
WA // YZ
c = d { Alternative interior anlges}
c = 30
a + b+ c = 180 {Angle sum property of triangle}
45 + b + 30 = 180
b + 75 = 180
b = 180 -75
b = 105

A clothing store purchases T-shirts for
$4.00 each and then marks up the price
of each by 55%. What is the markup and
new price of each T-shirt?
Answer:
The mark up is $2.20 and the new price of each T-shirt is $6.20.
Step-by-step explanation:
Before we find the new price of each T-shirt we must find the markup (by how much were raising the price).
The problem states each T-shirt costs $4.00, but then marks up the price of each by 55%.
Step 1 would be to find 55% of $4.00.
0.55 * 4 = 2.2
So that is the mark up, the price is going up by $2.20. To find the new price of each T-shirt, you take that $2.20 and add it to the original $4.00.
$4.00 + $2.20 = $6.20
So the mark up is $2.20 and the new price of each T-shirt is $6.20.
