Answer:
Area of A is 30
Step-by-step explanation:
total area = 280
amount of area given= 60+60+50+50
=220
area left = 280-220
=60
Area of 1 A= 60/2
=30
What is the approximate measure of the leg opposite of angle A???
Answer:
8.7 cm
Step-by-step explanation:
take 60 degree as reference angle
using sin rule
sin 60=opposite/hypotenuse
[tex]\frac{\sqrt{3} }{2}[/tex]=opposite/10
[tex]\frac{\sqrt{3} }{2} * 10[/tex]=opposite
[tex]\sqrt{3} *5[/tex] = opposite
[tex]5\sqrt{3}[/tex] =opposite
8.66=opposite
8.7 =opposite

Ciara is naking a new outfit she needs 2 1/2 yards of the fabric for the shawl and 1 3/4 yards of fabric for the dress. If she has 3 yards of fabric,how much more does she needs?If the dance outfit is charged at $16 per yard how much will the dance outfit cost
Answer:
1 1/4 yards
$20
Step-by-step explanation:
The amount of fabric more that she needs can be determined by subtracting the sum of the yards needed for the shawl and the dress from the fabric she has
sum of the yards needed for the shawl and the dress =
[tex]2\frac{1}{2} + 1\frac{3}{4}[/tex]
[tex]3\frac{2 + 3}{4}[/tex] = [tex]3\frac{5}{4}[/tex] = [tex]4\frac{1}{4}[/tex]
Yards needed
[tex]4\frac{1}{4} - 3[/tex] = [tex]1\frac{1}{4}[/tex]
cost of dance outfit = $16 x [tex]1\frac{1}{4}[/tex]
[tex]\frac{5}{4}[/tex] × $16 = $20
What is the value of x?
45°
m
(2x-5)
n
Answer:
x = 70
Step-by-step explanation:
The two angles are same side interior angles and same side interior angles add to 180
45+ (2x-5) = 180
Combine like terms
2x +40 = 180
Subtract 40 from each side
2x+40-40 =180-40
2x =140
Divide by 2
2x/2 = 140/2
x = 70
Answer:
x=70

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

The cost of a computer processor is directly proportional to its speed.
A 4GHz processor costs £400.
Find the cost of a 6GHz processor
Answer:
Step-by-step explanation:
If cost is directly proportional to speed, then the equation for this is
£ = ks, where k is the constant of proportionality. We need to solve for this first.
400 = k4 so
100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:
£ = (100)(6) so
£ = 600

May I please have help ?! Thanks ❤️
Help pls pls pls pls
Answer:
C
Step-by-step explanation:
Answer:
option c is correct
Step-by-step explanation:
y = 2x +5
5 = 2*0 +5
5 = 0 +5
5=5
y = 2x +5
9 = 2*2 + 5
=9 = 4 +5
9=9
y = 2x +5
13 = 2*4 +5
13 = 8 + 5
13 = 13
therefore option c is correct because it satisfies all the elements of x and y of the given function when we substitute the values.
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.
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

The area of a circle is 4π ft². What is the circumference, in feet? Express your answer in terms of \piπ.
Answer:
C = 4 pi ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
Solving for r
4 pi = pi r^2
Dividing each side by pi
4 = r^2
Taking the square root of each side
sqrt(4) = sqrt(r^2)
2 = r
Now we can find the circumference
C = 2 * pi *r
C = 2*pi*2
C = 4 pi ft
