Lady Di is planning a tea party for 30 ladies of the castle. She has asked one of the village bakers, the French lady Pia, to make tiny fancy tarts for the party. She has asked the other baker, Bart ·Graf if he would bake scones for everyone. She has sent instructions to each baker detailing how many of each kind of tart and scone she wants. She told Pia that each lady would eat three tarts, and she wanted one-third of the tarts to be apple tarts and half as many lemon tarts as apple. She also ordered 20 raspberry tarts, and half as many plum tarts as raspberry. She also wanted as many cheese tarts as plum, and the rest should be quince tarts. Lady Di thought two scones for each lady would be enough. So from Bart Graf, she ordered a blueberry scone for each lady and half as many raisin scones as blueberry. She wanted one-third as many cinnamon scones as blueberry and said the rest could be plain scones. The poor bakers were confused by Lady Di's orders, but of course, they wouldn't dare question her. Can you make two graphs, one for Pia and one for Bart, to show them how many of each tart and scones they needed to bake?

Classify this triangle.

A triangle with two sides of equal length. The angle where these two sides meet is ninety degrees.
A. Acute scalene triangle
B.Obtuse isosceles triangle
C. Right isosceles triangle
D Right scalene triangle

Answers

It is a right isosceles triangle, C

A triangle with two sides of equal length and the angle where these two sides meet is 90° is Right isosceles triangle. Therefore, option C is the correct answer.

What is a right triangle?

A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.

A right triangle with two equal-length legs is called an isosceles right triangle. The corresponding angles would also be congruent because the lengths of the two legs of the right triangle are equal. As a result, the two acute angles and two legs of an isosceles right triangle are congruent.

Therefore, option C is the correct answer.

Step-by-step explanation:

(5^2 – 10) ÷ 5 × 2^3?
i know its 24 but can someone please explain it to me?

Answers

you have to first do parentheses so we start in there: 5^2= 25 so 25-10= 15, we next move on to exponents (which is also why we did that first in the parentheses btw) so 2^3= 8, now we’re gonna go in order since it’s all multiplication and division: 15/5=3, then 3x8=24!
Ok! So because we have to use the order of operations you have to start inside the parentheses 5^2=25 then 25-10=15 next you have to do you second set of exponents outside the parentheses 2^3= 8 now you have the equation now u just solve left to right

The eggs of birds and other animals come in many different shapes and sizes. Eggs often have a shape that is nearly spherical. When this is true, you can use the formula for a sphere to find their volume.

Fossilized spherical eggs of dinosaurs called titanosaurus sauropods were found in Patagonia. These eggs were 11 centimeters in diameter. Find the volume of an egg. Round your answer to the nearest tenth.

Answers

Answer:

696.9 cm^3 to the nearest tenth.

Step-by-step explanation:

Radius of the egg = 1/2 * 11 = 5.5 cm.

Volume = 4/3 * pi * 5.5^3

= 696.9099703

-2x-5y=3 3x-8=-6 solve by substition

Answers

Maybe use photo math i guess

Answer:

x = 2/3

y = -13/15

Step-by-step explanation:

3x – 8 = -6

+8 +8

[addition property of equality]

3x = 2

÷3 ÷3

[division property of equality]

x = 2/3 → -2x – 5y = 3

[substitution property]

-2(2/3) – 5y = 3

[distributive property]

-4/3 – 5y = 3

[Create the proportional equivalent of each term so that all terms share the same denominator]

-4/3 – 15y/3 = 9/3

[multiplication property of equality]

3 ( -4/3 – 15y/3 ) = 3 ( 9/3 )

[distributive property]

-4 – 15y = 9

+4 +4

[addition property of equality]

-15y = 13

÷-15 ÷-15

[division property of equality]

y = -13/15
