the ratio of the measures of the sides of a triangle is 2:7:6. if the perimeter of the triangle is 345 yards, find the measure of the median side.
Answer:
the sides are 46, 161, 138 respectively to sides 2, 7, 6
Step-by-step explanation:
2+7+6=15
345/15=23 this is our factor
2x23=46
7x23=161
6x23=138

Find the side of cube whose total surface area is 486 sq.cm
Answer:
9 cm
Step-by-step explanation:
The cube has 6 square faces.
Divide surface area by 6 to find area of 1 face
area = 486 ÷ 6 = 81 cm²
The area of a square = s² ( s is the side length ) , then
s² = 81 ( take the square root of both sides )
s = [tex]\sqrt{81}[/tex] = 9 cm
Forty percent of the 70 buttons in the box had 5 holes
a. What fraction of the buttons did not have 5 holes?
b. How many buttons did not have 5 holes?
Answer: a. 0.6
b. 42 buttons
Step-by-step explanation:
a. What fraction of the buttons did not have 5 holes?
Since forty percent of the 70 buttons in the box had 5 holes, the number of buttons in the box that doesn't have 5 holes will be:
= 100% - 40%
= 60%
= 60/100
= 0.6
b. How many buttons did not have 5 holes?
This will be:
= 60% × 70
= 0.6 × 70
= 42 buttons
A camera has a listed price of $594.99 before tax. If the sales tax rate is 7.25% , find the total cost of the camera with sales tax included. Round your answer to the nearest cent, as necessary.
Answer:

Answer:
sin2θ = - [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
Given
cosθ = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex] and in fourth quadrant
Then this is a 3- 4- 5 triangle with opposite side = 4
sinθ < 0 in fourth quadrant, then
sinθ = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{4}{5}[/tex]
Using the double angle identity for sine
sin2θ = 2sinθcosθ
= 2 × - [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex] = - [tex]\frac{24}{25}[/tex]

Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
Answer:
Númer total de ladrillos= 256
Step-by-step explanation:
Dada la siguiente información:
Total de pisos= 16
Total de ladrillos por piso= 16
Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:
Número total de ladrillos= total de ladrillos^2
Número total de ladrillos= 16^2
Númer total de ladrillos= 256
En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

Cameras R Us has a sale for 25% off camera bags, which is a discount of $20. To find the original cost of the camera bag, Tara creates the following diagram.
A 2-column table with 6 rows. Column 1 has entries 20 percent, 20 percent, 20 percent, 20 percent, 20 percent, Total 100 percent. Column 2 has entries 25 dollars, 25 dollars, 25 dollars, 25 dollars, 25 dollars, blank total.
What errors did Tara make in her diagram? Check all that apply.
There should be 5 rows labeled 20%.
The 25 should be for each percent, not dollar amounts.
The percents do not add up to a whole of 100%.
There should be 4 columns of 25% that each equal $20.

Answer:
∠B = 141
Step-by-step explanation:
n - > number of sides
n = 7
Sum of all interior angles = (n -2 ) * 180
= 5 * 180 = 900
∠B + 148 + 90 + 142 + 130 + 129 + 120 = 900
∠B + 759 = 900
∠B = 900 - 759 = 141

Coordinates (2,5) (6,11) what's the equation of the line?
Answer:
y= 2x+1
Step-by-step explanation:
Using the general linear form y=mx+c
First find the gradient: change in y/change in x
11-5/6-2 = 6/3= 2
y=2x+c
Secondly find out c:
Use one of the coordinats
5= 2(2)+c
5=4+c
-4
1=c
y= 2x+1

How many of these should be Ristretto capsules? I
Note Please make your final answer clear by writing ... Ristretto capsules
[3]
Answer:
Ristretto will be 230 capsules i think
Step-by-step explanation:
50 customers = 50 capsules
