Describe how to compare the two ratios 5:8 to 7:9. Tell each step to set up the ratios, then explain what to do to be able to compare the ratios. Finally make sure to answer how the ratios compare. ~ 100 POINTS AND ILL GIVE YOU BRAINLIEST IF YOU ANSWER CORRECTLY AND 5 SENTENCES NEEDED
Step-by-step explanation:
The ratio's can be expressed as fractions and you may compare those.
5 : 8 = 5/87 : 9 = 7/9In order to compare fractions you need to bring them into equal denominator.
8 and 9 have LCM of 8*9 = 72 since they have no common factors.
The equivalent fractions with common denominator are:
5/8 = 9*5/(9*8) = 45/727/9 = 8*7/(8*9) = 56/72Now we can compare the fractions:
45/72 < 56/72, since 45 < 56Find the base of the triangle whose area is 28 cm2 and height is 7 cm.

What is the answer?
Answer:
x = 60
Step-by-step explanation:
Because the triangle looks like an equalateral triangle meaning all sides and angles are congruent
So triangle equals 180 degrees and 60 times 3 equals 180
Step-by-step explanation:
x + x + x = 180° ( sum of interior angle of triangle is 180°)
3x = 180°
x = 180° / 3
x = 60°

The blueprint for the Moreno's living room has a scale of . The family wants to 2 inches= 3 feet use a scale of 1 inch =4 feet. What is the width of the living room on the new blueprint?
Answer:
If I am understanding the question correctly, every 6 feet in real life will be equivalent to 1 inch "on paper", or in the blueprint. Using dimensional analysis, which is a methodology for converting from one unit to another, we have:
18 feet * 1 inch / 6 feet = 3 inches
On the other axis,
24 feet * 1 inch / 6 feet = 4 inches
Therefore, the blueprint for this 18x24 foot room, with a scale of 6 feet:1inch, should be 3x4 inches.
Factor the polynomials comletely, then solve 9x^2 +66x+21 = 0
Answer:
x= -1/3
x = -7
Step-by-step explanation:
9x^2 +66x+21 = 0
a=9 b=66 c=21
quadratic formula
x=(-b +/- square root of (b^2 – 4ac))/(2a)
x = (-66 +/- square root of (66^2 -4*9*21))/(2*9)
x = (-66 +/- square root of (4356 -756))/(18)
x = (-66 +/- square root of (3600))/(18)
x = (-66 +/- 60)/18
split the fraction
(-66 +/- 60)/18 = -6/18 and -126/18 because of the +/-
x = -6/18 x = -126/18
x = -1/3 x = -7
[tex]~~~~~~9x^2+66x+21 = 0\\\\\implies 3(3x^2+22x+7)=0\\\\\implies 3x^2+22x+7=0\\\\\implies 3x^2 +21x +x +7=0\\\\\implies 3x(x+7) +(x+7)=0\\\\\implies (x+7)(3x+1)=0\\\\\implies x = -7~~ \text{or}~~ x =-\dfrac 13[/tex]

Sophia, a yoga instructor at Yoga for You, selected random samples of 210 students from a nearby high school and 210 students from a nearby college to compare levels of physical fitness. The mean and standard deviation of the fitness levels of the high school students were 82 and 14 respectively. The mean and standard deviation of the fitness levels of the college students were 86 and 17 respectively. She conducted a two-sided t-test with a resulting t-value of 2. 63. Lf a = 0. 05, what is an appropriate conclusion from this study?
Because the sample means only differ by four, the population means are not significantly different.
Because the second group has a larger standard deviation, their mean fitness score is significantly higher.
Because the second group has a larger standard deviation, the mean fitness score of the first group is significantly higher
Because the p-value is greater than a 0. 05, the mean fitness scores for the two groups of students are not significantly different.
Because the p-value is less than a 0. 05, the mean fitness scores for the two groups of students are significantly different
Because the p-value is less than 0.05, the mean fitness scores for the two groups of students are significantly different
========================================================
Explanation:
Use a T calculator to find that P(T > 2.63) = 0.00459 approximately when we have 209 degrees of freedom.
Double this to get 2*0.00459 = 0.00918 and this is the approximate p-value
Since the p-value is less than alpha = 0.05, this means we reject the null and conclude that the two population means are significantly different.

A 50:1 scale drawing of your garden shows dimensions of 12 cm by 10.5 cm. how many
square cm are covered by your real garden?
50:1 scale drawing -> Both sides of the garden is shrinked by 50 times.
We can calculate the area of the shrinked scale drawing : 12 x 10.5 = 126 (cm2)
Since both sides are shrinked by 50 times -> The real area get shrinked by 2500 times.
So, we can find the real area : 126 x 2500 = 315000 (cm2)
