Answer:
There are 8 more girls than boys.
Step-by-step explanation:
Ratios are easier to read as fractions (at least to me), so 5:7 would be 5/7. When you multiply both the top and the bottom by 4, you get 20/28, meaning that there are 20 boys and 28 girls. 28-20=8, so there are 8 more girls than boys.
Which property of equality would you use to solve the following equation? W/5=10
Answer:
Multiplication property of equality because we need to multiply both sides by 5 to get rid of the denominator, so we get w = 50.
Hope this helps and brainliest please
Answer:
You would use the multiplication property of equality and by using that you get W=50.

The sum of 43 and z is equal to 72.98. Enter the equation that represents the description.
sum is an answer to an addition problem, so we have to add 43 and z. z+43=72.98
Subtract 43 on both sides.
z=29.98

hope it helps
Answer:
43 + z = 72.98
Step-by-step explanation:
Sum meaning add the two (or more numbers together) we get 43+ z = 72.98
If you're trying to find "z" simply subtract 43 from 72.98 to get 29.98 as z

What is the value of 4)1/8 divided by 5)1/2
Answer:
I'm assuming that you meant to type: The question is x/5=1/2+1/8 ; X= ?
If so, we're solving for x.
x/5 = 1/2 + 1/8
2 is a factor of 8, so let's start with common denominators.
x/5 = 1/2 *(4/4) + 1/8
x/5 = 4/8 + 1/8
x/5 = 5/8 As long as we just need to know the value of x, let's use inverse operations.
x/5 *5 = 5/8 *5
x = 25/8 or 3.125
What is the solution to the equation y/y-4 -4/y+4=32/y2-16?
Answer:
No solution
Step-by-step explanation:
For the equation given, we have an alternate form that is
[tex]\dfrac{y^2 + 16}{y^2-16} =\dfrac{32}{y^2-16}[/tex]
It is clear that
[tex]y^2+16 = 32 \implies y=4, y=-4[/tex]
But the denominator goes to zero and it is undefined.
If you take
[tex]$\lim _{y\to 4}\left(\dfrac{y^2+16}{y^2-16}\right)$[/tex]
you'll see that
[tex]$\lim _{y\to 4^-}\left(\dfrac{y^2+16}{y^2-16}\right) = -\infty$[/tex]
[tex]$\lim _{y\to 4^+}\left(\dfrac{y^2+16}{y^2-16}\right) =\infty$[/tex]
It diverges and the limit does not exist.

[tex]Your[/tex] [tex]answer[/tex] [tex]would[/tex] [tex]be.[/tex]
[tex]g/4 = 24 // - 24\\g/4-24 = 0\\1/4*g-24 = 0 // + 24\\1/4*g = 24 // : 1/4\\\g = 24/1/4\\g = 96\\g = 96[/tex]
[tex]- Yaoii[/tex]
Answer:
g = 96
Step-by-step explanation:
Rewrite : g ÷ 4 = 24
Write the division as a fraction : 1/4g = 24
Multiply both sides : 1/4g = 24
Multiply both sides of the eqaution by 4 :
g = 96
Final answer g = 96

Answer:
[tex]\frac{\sqrt{24}- \sqrt{54} }{\sqrt{6}}[/tex] = -1 [tex]\sqrt{\frac{9}{20}[/tex]*[tex]\frac{10\sqrt{2} }{3\sqrt{5} }[/tex] = 1.4142[tex]\frac{10\pi\sqrt{2}-8\pi\sqrt{2}}{2\sqrt{2}}[/tex] = π =3.14159[tex]\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}[/tex] = π² = 9.8696Explanation:
1.) Rewrite √24 = [tex]\sqrt{4*6} = 2\sqrt{6}[/tex] Rewrite √54 =[tex]\sqrt{9*6}= 3\sqrt{6}[/tex]
Divide both terms by the denominator; √6 cancels. 2-3 = -1
2.) Rewrite as [tex]\frac{3}{2\sqrt{5}}[/tex] ×[tex]\frac{10\sqrt{2}}{3\sqrt{5}}[/tex] The 3's cancel. 10/2 = 5√2 in the numerator.
√5 × √5 = 5 in the denominator. The 5's cancel.
That leaves √2 ≈1.4142
3.) Divide the terms in the numerator by the term in the denominator.
√2's cancel. 10π/2 = 5π 8π/2 = 4π
Subtract and we are left with π = 3.14159
4.) [tex]\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}[/tex] The square roots are reciprocals. They multiply to 1
We are left with π × π = π² ≈ 9.8696

Estimate:
20 is 22% of what number?
Answer:
90.9091 yeah I'm pretty sure
The number 20 is 22% of 90.91.
Percentage is a way of expressing a portion or fraction of a whole as a proportion of 100. It is denoted by the symbol "%". Percentages are commonly used to compare relative values, express ratios, or represent portions of a whole.
To estimate the number that 20 is approximately 22% of, we can set up the equation:
0.22 x = 20
Here, x represents the unknown number we are trying to estimate.
To estimate x, we can divide 20 by 0.22:
x ≈ 20 / 0.22
x ≈ 90.91
Therefore, 20 is 22% of 90.91.

Using traditional methods, it takes 95 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 260 students and observed that they had a mean of 94 hours. Assume the standard deviation is known to be 6. A level of significance of 0.01 will be used to determine if the technique performs differently than the traditional method. Is there sufficient evidence to support the claim that the technique performs differently than the traditional method
Answer:
There is not sufficient evidence to support the claim that the technique performs differently than the traditional method.
Step-by-step explanation:
The null hypothesis is:
[tex]H_{0} = 95[/tex]
The alternate hypotesis is:
[tex]H_{1} \neq 95[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A researcher used the technique with 260 students and observed that they had a mean of 94 hours. Assume the standard deviation is known to be 6.
This means, respectively, that [tex]n = 260, X = 94, \sigma = 6[/tex]
The test-statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{94 - 95}{\frac{6}{\sqrt{260}}}[/tex]
[tex]z = -2.69[/tex]
The pvalue is:
2(P(Z < -2.69))
P(Z < -2.69) is the pvalue of Z when X = -2.69, which looking at the z-table, is 0.0036
2*(0.0036) = 0.0072
0.0072 < 0.01, which means that the null hypothesis is accepted, that is, there is not sufficient evidence to support the claim that the technique performs differently than the traditional method.

Felicia has a ladder that is 11 ft long. She wants to lean the ladder against a vertical wall so that the top of the ladder is 9.5 ft above the ground. For safety reasons, she wants the angle the ladder makes with the ground to be no greater than 75°. Will the ladder be safe at this height? Show all your work and draw a diagram to support your answer.
Answer:
See attached diagram
We have
GT = 9.5 ftBT = 11 ftLet's find angle x and compare with the safety requirement
GT/BT = sin x9.5/11 = sin xx = arcsin (9.5/11)x = 59.7° < 75°The angle we got is less than 75° so it is safe to use
