Answer:
20
Step-by-step explanation:
Because 5(4) is the same thing s 5*4, so it is 20.
Hope it helps!
Answer:
20
Step-by-step explanation:
Z=4
If a letter is next to a number it means to multiple
So since z=4, replace 5z with 5(4) and you get 20

In ΔIJK, k = 3.6 inches, i = 1.3 inches and ∠J=13°. Find the length of j, to the nearest 10th of an inch.
Answer:
5.6 inches
Step-by-step explanation:
let c = length of 'j'
I used the Law of Cosines: [tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] -2ab· cosC
= (1.3)^2 + (3.6)^2 - 2(1.3)(3.6) x 0.97
Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. Fewer than 400 tickets in total were sold. If x stands for the number of lawn tickets sold and y stands for the number of seat tickets sold, write an equation you could make for fewer than 400 tickets were sold. Please do not add any space between characters in your answer. For example: 2x+3y>500
Answer:
x+y< 400
Step-by-step explanation:
x = Number of lawn tickets sold
y = Number of seat tickets sold
We are told that: Fewer than 400 tickets in total were sold.
Hence, this means that, less than 400 tickets were sold.
The symbol for less than = <
Therefore, the equation you could make for fewer than 400 tickets were sold is given as:
x+y< 400
Answer: x+y< 400

Answer:
3 and 2 is 40 and 4 is 140
Step-by-step explanation:
in the comments
Answer:
measure of angle 4 is 140°
measure of angle 1 is 140° (given)
measure of angle 3 is 40°
measure of angle 2 is 40°
Step-by-step explanation:
We're given that one angle is equal to the measure of 140° (we'll make this one be angle 1)
because of vertical angles theorem, which states that angles that are opposite to each other and are formed by two intersecting lines will be congruent.
So that means that measure of angle 4 will also be 140°
Because of vertical angles theorem, that means that <3 is ≅ to <2 (we can make them be x)
The sum of all the angles will equal to 360° (since it's a full angle)
Here's the equation:
140+140+x+x=360
simplify
280+2x=360
2x=80
x=40°
Which means that <3 and <2 both equal 40°
Hope this helps!
-3x + 6 = 18 show full work please
Answer:
Step-by-step explanation:
-3x + 6 = 18
-3x - 6 = 18 - 6
-3x = 12
x = -4
Answer:
-4
Step-by-step explanation:
-3x + 6 = 18
subtract 6 from both sides
-3x + 6 - 6 = 18 - 6
-3x = 12
divide -3 to both sides
-3x/-3 = 12/-3
x = -4

why is the equation y-y1=m(x-x1) called the point-slope form?
Answer:
The equation of the line with slope m = 2 and passing through the point (1, 1) will be:
[tex]y = 2x[/tex]
Step-by-step explanation:
We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointThe formula [tex]y-y_1=m\left(x-x_1\right)[/tex] is termed as the point-slope form of the line equation because if we know one point on a certain line and the slope of that line, then we can easily get the line equation with this formula and, hence, determine all other points on the line.
For example, if we are given the point (1, 1) and slope m = 2
Then substituting the values m = 2 and the point (1, 2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 2 = 2(x-1)[/tex]
[tex]y - 2 = 2x-2[/tex]
[tex]y = 2x-2+2[/tex]
[tex]y = 2x[/tex]
Therefore, the equation of the line with slope m = 2 and passing through the point (1, 1) will be:
[tex]y = 2x[/tex]

What is the result when 4x3 + 19x2 + 29x + 14 is divided by 4x + 7?
Step-by-step explanation:
4x³ + 19x² + 29x + 14
= (4x³ + 7x²) + (12x² + 21x) + (8x + 14)
= x²(4x + 7) + 3x(4x + 7) + 2(4x + 7).
= (x² + 3x + 2)(4x + 7).
Hence 4x³ + 19x² + 29x + 14 divided by 4x + 7 is x² + 3x + 2 or (x + 1)(x + 2).

There are 9 people at a sleepover. Each
person wants 2 slices of pizza If a large
pizza contains 8 slices, how many large
pizzas does Ben need to order so that
everyone gets what they want?
PLEASE HELP ME WITH THISSSSSSSSSSSSSSSSSSSSS QUICKKKKKK
Answer:
3
Step-by-step explanation:
9 people want 2 so 9*2=18
8*2= 16 not enough
8*3=24 enough
You can't order parts of a pizza and if you get less there won't be enough so if you get three pizzas there will be enough for all 9 people.
Answer: 3
9 people, each want 2
SO - 9 x 2 = 18
you have 8 slices in each pizza
2 pizzas = 16 (not enough)
3 pizzas = 24 (everyone get 2)
So 3 pizzas

7x + 12 = 5x − 8
Subtract 12 from both sides7x + 12 - 12 = 5x - 8 + 12
Simplify7x = 5x - 20
Subtract 5x from both sides7x - 5x = 5x - 20 - 5x

In triangle VUT, find the value of x. Round to the nearest tenth.
Answer:
X = 29.9
Step-by-step explanation:
Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
Selecting the angle of 18°:
Tangent Ratio:
[tex]\displaystyle \tan 18^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
[tex]\displaystyle \tan 18^\circ=\frac{X}{92}[/tex]
Solving for X:
[tex]\displaystyle X=92\tan 18^\circ[/tex]
Operating:
[tex]\displaystyle X=92*0.325[/tex]
X = 29.9

Answer:
The volume of the cone = 101 cubic inches.
Step-by-step explanation:
Given
Radius of the cone = r = 4 in
Height h of the cone = h = 6 in
To determine
The volume in cubic inches rounded to the nearest whole number.
Using the formula to determine the volume of the cone
V = πr²h/3
substitute r = 4, h = 6, and π = 3.142 in the formula
V = (3.142) (4)²(6) / 3
V = (3.142) (4)² (2)
V = (3.142) (16) (2)
V = (3.142) (32)
V = 100.544
V ≈ 101 cubuc inches (rounded to the nearest whole number)
Therefore, the volume of the cone = 101 cubic inches.
