Answer:
0.475
Step-by-step explanation:
It makes it easier for people to turn fraction to decimal.
So, 1/4 in decimal is 0.25.
1.9•0.25=0.475
Sorry if I'm wrong I'm in 8 grade I learned it in this year

Fill in the blank. In the triangle below, x=__. Round your answer to two decimal places.
Given:
The figure of a right triangle.
To find:
The value of x.
Solution:
In a right triangle,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
In the given right angle triangle,
[tex]\tan 52^\circ=\dfrac{x}{35}[/tex]
[tex]1.2799\times 35=x[/tex]
[tex]44.7965=x[/tex]
Approximate the value to two decimal places.
[tex]x\approx 44.80[/tex]
Therefore, the value of x is about 44.80 units.

Calculate the length of AC, to the nearest tenth of a centimeter.
Answer:
AC ≈ 11.0 cm
Step-by-step explanation:
Using Pythagoras' identity in Δ CDE and Δ ADE
CE² + DE² = DC²
CE² + 7² = 8²
CE² + 49 = 64 ( subtract 49 from both sides )
CE² = 15 ( take the square root of both sides )
CE = [tex]\sqrt{15}[/tex]
-------------------------------------------------------
AE² + DE² = DA²
AE² + 7² = 10²
AE² + 49 = 100 ( subtract 49 from both sides )
AE² = 51 ( take the square root of both sides )
AE = [tex]\sqrt{51}[/tex]
Then
AC = AE + CE = [tex]\sqrt{15}[/tex] + [tex]\sqrt{51}[/tex] ≈ 11.0 cm ( to the nearest tenth )
A Statistics class has a test average of 87 with a standard deviation of 2.1. Find the z-score that corresponds to Kate's test score of 93. (Round to the nearest hundredths)
Answer:
2.86
Step-by-step explanation:
So I'm pretty sure we don't want the probability, just the zscore
to find the zsore subtract the mean and divide by the standard deviation
(93-87)/2.1= 2.86

Question 6 of 9 Last week, Hayden rode his bike 5 times. Each time, he biked a 3-mile path, a 2-mile path, and a 2 1 4 2 1 4 -mile path. Which expression represents the total number of miles he biked? A. 5 × ( 3 + 2 + 2 1 4 ) 5 × ( 3 + 2 + 2 1 4 ) B. 5 + ( 3 × 2 × 2 1 4 ) 5 + ( 3 × 2 × 2 1 4 ) C. 5 × ( 3 × 2 × 2 1 4 ) 5 × ( 3 × 2 × 2 1 4 ) D. 5 + ( 3 + 2 + 2 1 4 )
Answer:
A. 5 × ( 3 + 2 + 2 1/4 )
Step-by-step explanation:
Hayden rode his bike 5 times. Each time, he biked a 3-mile path, a 2-mile path, and a 2 1/4 -mile path.
The expression represents the total number of miles he biked is calculated as:
The number of times he rode his bike × (sum of the number of miles he biked)
= 5 × ( 3 mile + 2 miles + 2 1/4 miles)
= 5 × (3 + 2 + 2 1/4)
Therefore, Option A is the correct option
What is the remainder when x^3-8x^2+20x-16 is divided by x+2?
Answer:
(x - 4)(x - 2)²
Step-by-step explanation:
x³ - 8x² + 20x - 16
x³ - 4x² + 4x - 4x² + 16x - 16
x(x² - 4x + 4) - 4(x² - 4x + 4)
(x - 4)(x² - 4x + 4)
(x - 4)(x² - 2x - 2x + 4)
(x - 4)(x(x - 2) - 2(x - 2))
(x - 4)(x - 2)(x - 2)
(x - 4)(x - 2)²
(x - 4)(x - 2)²
Answer:
-96
Step-by-step explanation:
x+2=0 take 2 to the other side which will be -2
the -2 you sub it into the quotient and calculate

devi bought 7 skirts at x$ each n skirts at 12$ each 2n +1 at 15 each a nd 4 skirts at $3x find the total
Answer:
4(19x + 42n + 15)
Step-by-step explanation:
Devi bought 7 skirts at $x each, n skirts at $12 each, (2n + 1) skirts at $15 each and 4 skirts at $3x each. Find the total cost of the skirts she bought.
total cost of the skirt bought can be determined by adding the total costs of each shirt bought
7 skirts at $x each = $7x
n skirts at $12 each = $12n
(2n + 1) skirts at $15 = (2n + 1) x 15 = 30n + 15
4 skirts at $3x each = $12x
7x + 12n + 30n + 15 + 12x
combine like terms
19x + 42n + 15

Find the polynomial function with the given zeros.
X = 2, X = 5, X = -1 and x = -3
(x), (x-2), (x-5), (x-5), (x-7) and (x-9) are NOT zeros, they are FACTORS. The zeros are 0, 2, 5, 5, 7, and 9. Since 5 is listed twice it is said to be a zero of multiplicity 2. To find a polynomial with those zero, we start by setting x equal to each zero: x=0, x=2, x=5, x=5, x=7, and x=9. Then we subtract the zero on the right from both sides of each of those 6 equations: x-0=0, x-2=0, x-5=0, x-7=0, x-9=0 Then we use the principle that equals multiplied by equals gives equals. So we multiply all the left sides together and all the right sides together. (Multiplying all the right sides together just gives 0.) (x-0)(x-2)(x-5)(x-5)(x-7)(x-9) = 0 And since x-0 is just x, we have (x)(x-2)(x-5)(x-5)(x-7)(x-9) = 0 Those are the factors you gave. But again, the zeros are 0,2,5,5,7,9

Answer:
obtuse scalene triangle
Step-by-step explanation:
Connecting 3 points will make a triangle. The sides are different lengths, and the largest angle is more than 90°. The figure is an obtuse scalene triangle.
I need help finding the solution
==========================================================
Explanation:
If you apply the distance formula, you should find that triangle DEF has the following side lengths
DE = 5EF = 5FD = sqrt(50)Those distances are exact. The sqrt(50) approximates to 7.071
Since 7.071 is the longest side, we'll make c = sqrt(50)
Then we have a = 5 and b = 5
Note that a^2+b^2 = 5^2+5^2 = 50 while c^2 = (sqrt(50))^2 = 50
Both a^2+b^2 and c^2 are equal to 50.
That means a^2+b^2 = c^2 is a true equation for the a,b,c values mentioned.
By the converse of the pythagorean theorem, we have shown that triangle DEF is a right triangle.
---------------
Side notes:
Triangle DEF is also isosceles because a = b = 5.If a^2+b^2 > c^2, then the triangle is acuteIf a^2+b^2 < c^2, then the triangle is obtuseIf a = b = c, then we have an equiangular triangleAnswer:
right
Step-by-step explanation:
we should find the distance of
DE
EF
FD
for DE
D(2,3) = (x1,y1)
E(5,7) = (x2,y2)
disatnce = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
=[tex]\sqrt{(5-2)^2 + (7-3)^2}[/tex]
=[tex]\sqrt{3^2 + 4^2}[/tex]
=[tex]\sqrt{16+9}[/tex]
=[tex]\sqrt{25}[/tex]
=5 units
for EF
E(5,7) = (x1 , y1)
F(9,4) = (x2 , y2)
distance =[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
=[tex]\sqrt{(9-5)^2 + (4-7)^2}[/tex]
=[tex]\sqrt{(4)^2 + (-3)^2}[/tex]
=[tex]\sqrt{16 + 9}[/tex]
=[tex]\sqrt{25}[/tex]
=5 units
for DF
D(2,3) = (x1 , y1)
F(9,4) = (x2 , y2)
diatance =[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
=[tex]\sqrt{(9-2)^2 + (4-3)^2}[/tex]
=[tex]\sqrt{7^2 + 1^2}[/tex]
=[tex]\sqrt{49 + 1}[/tex]
=[tex]\sqrt{50}[/tex]
=[tex]5\sqrt{2}[/tex]
It is a right angle triangle .
to prove right angle triangle
sum of square of two smaller sides = sum of square of longest side
5^2 + 5^2 =[tex](5\sqrt{2})^2[/tex]
25 + 25 = 52 *2
50 + 50
hence proved.
