sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm.
Strike441 [17]

Answer:

220 cm

Step-by-step explanation:

We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be 2(l+w), where l is the rectangle's length and w is the rectangle's width. We are given that l=70 and w=40. Therefore, 2(70+40)=2*110=220 cm of ribbon will be needed. Hope this helps!

In triangle ABC find b to the nearest degree given a=7 b=10 and c is a right triangle
eimsori [14]

Answer:

∠B =55.00797173^{\circ}

Step-by-step explanation:

Given : a=7 b=10 and C is a right triangle

solution :

refer the attached figure .

Since ΔACB is right angled triangle so we will use trigonometric ratios .

tan\theta=\frac{perpendicular}{base}

Perpendicular = b =10

Base=a=7

Putting value in formula:

tanB=\frac{10}{7}

tanB=1.42857

B=tan^{-1}1.42857

B=55.00797173^{\circ}

Thus ∠B =55.00797173^{\circ}

Which of the following is the inverse of y=6^x? y=log_(6)x, y=log_(x)6, y=log_((1)/(6))x, y=log_(6)6x
kolezko [41]

Answer:

y=log_(6)x

Step-by-step explanation:

From the definition of logarithm:

x = log_b y <---> y=b^x

In our case, we have

y=6^x

which means that b=6, therefore the inverse function is

x=log_6 y

which can be rewritten by switching x and y:

y=log_6 x
