Answer:

Step-by-step explanation:

suface area of base=1/2×9×7.8=9×3.9=35.1 yd²

lateral surface area=3×1/2×9×10=135 yd²

total surface area=135+35.1=170.1 yd²

i assumed it is an equilateral triangular base.

as √(7.8²+4.5²)=9.0049≈9

3. The surface area of the sphere is 30 m2. Find the radius of the sphere.

pickupchik [31]

Answer:

Step-by-step explanation:

The formula for the surface area is A = 4πr². This formula can be solved for r² and then the result solved for the radius, r:

r² = -------- The radius of the sphere is as follows:

4π

√(30 m²)

-------------- meters

Sarah made a necklace using 5 times as many blue beads as white beads. She used a total of 30 beads. How many blue beads did Sar

iogann1982 [59]

Let

x-------> the numbers of blue beads

y-------> the numbers of white beads

we know that

$x+y=30$ --------> equation $1$

$x=5y$ --------> equation $2$

Substitute equation $2$ in equation $1$

$(5y)+y=30\\ 6y=30\\ y=30/6\\ y=5$

Find the value of x

$x+y=30\\ x+5=30\\ x=30-5\\ x=25$

therefore

the answer is

the numbers of blue beads is $25$

If r varies directly as p and inversely as q2, and r = 27 when p =3 and q = 2, find r when p = 2 and q= 3

WITCHER [35]

Answer:

k = 36 and r = 8

Step-by-step explanation:

Given that r varies directly as p and inversely as q² then the equation relating them is

r = $\frac{kp}{q^2}$ ← k is the constant of variation

To find k use the condition r = 27 when p 3 and q = 2, thus

27 = $\frac{3k}{4}$ ( multiply both sides by 4 )

108 = 3k ( divide both sides by 3 )

k = 36

r = $\frac{36p}{q^2}$ ← equation of variation

When p = 2 and q = 3, then

r = $\frac{36(2)}{3^2}$ = $\frac{72}{9}$ = 8
