Paint is red : blue in a ratio of 2 : 4. If 5 litres of red is used how much blue is used

Answers

Answer 1

Answer:
so since the ratio of red paint to blue paint is 2:4 and you can simplify 2:4 into 1:2 and because 5 liters of paint is used you would have to multiply the 2 from the simplified ratio by 5 so you could get the answer 2*5 and that equals 10

What is the measurement of STU?

Answers

Triangles UTR and RTS are congruent, because they're both right triangles, RS=RU and side TR is in common.

This implies that angles RTS and RTU are congruent, and thus we have

$5w-69=w+3 \iff 4w=72 \iff w=(72)/(4)=18$

Finally, angle STU is the sum of RTS and RTU, which is the same as 2RTU, since they have the same measure. So, we have

$RTS+RTU=2RTU=2(w+3)=2w+6$

and since w=18, we have

$2w+6=2\cdot 18+6=36+6=42$

A flower bed is in the shape of a triangle, with a base of 15 feet and a height of 9 feet. What is the area of the flower bed?24 square feet
32.5 square feet
67.5 square feet
135 square feet

Answers

67.5 square feet

Working
A = 1/2*base*height
A = 1/2*15*9
A = 67.5 sq. feet

Answer:

67.5

Step-by-step explanation:

If one of the non-right angles in a right triangle is equivalent to an angle in another right triangle, what can you say about the two triangles? What does that mean about the sides of the triangles? Explain.

Answers

The triangles are similar, they aren't congruent (identical) though as we don't know if they share a common side

The triangles are similar by AAA. AAA however does not prove congruency. The side would be proportional.

Emma is debating whether to use a straightedge and compass or a computer drawing program to complete a construction of a square inscribed in a circle. Which method do you think would take the longest to complete the construction and why?

Answers

Using a straightedge and compass will take the longest because Emma will have to work out the measurements herself and draw each inscribed triangle. Using a computer programme, the computer will do it for her and the results will definitely be accurate.

Answer:

Step-by-step explanation:

Using technology takes longer. Using a straightedge and a compass just requires you to find the circles bisector which takes no time at all. Using technology requires you to have a circle with a center point and a radius as AB, then you draw connecting lines, make intersections, draw point E on the segment DB, follow the entire perpendicular line construction that requires two additional circles and then in the end you’ll have BHDI as a square.
