Rewrite each fraction with a denominator of 10 7/2= 3/5=
Answer:
7/2 = 35/10
3/5 = 6/10
Step-by-step explanation:
To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).
7/2
7 × 5 / 2 × 5
35/10
3/5
3 × 2 / 5 × 2
6/10
Answer:
7/2 = 35/10
3/5 = 6/10
Step-by-step explanation:
[tex]\frac{7}{2}\cdot \frac{5}{5}=\frac{35}{10}[/tex]
[tex]\frac{3}{5}\cdot \frac{2}{2}=\frac{6}{10}[/tex]

Find 50% of 152:
Find 25% of 152:
Find 75% of 152:
Answer:
76
38
114
Step-by-step explanation:
50% of 152
= ( 50 / 100 ) x 152
= ( 1 / 2 ) x 152
= 152 / 2
= 76
25% of 152
= ( 25 / 100 ) x 152
= ( 1 / 4 ) x 152
= 152 / 4
= 38
75% of 152
= ( 75 / 100 ) x 152
= ( 3 / 4 ) x 152
= ( 3 x 152 ) / 4
= 3 x 38
= 114
an object is launched at 4 ft./s from 88 foot tall platform the objects height H in feet after T seconds is given by the equation H=-16T^2+8t+80 when does the object strike the ground
Answer:
1.5seconds
Step-by-step explanation:
When the ball hits the ground, the height is equal to zero. So find t when H=0:
H=16t²+8t+80
0=16t²+8t+80
0=2t²+t+10
0=(2t-3)(t+2)
So (2t-3)=0, or (t+2)=0
So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds
When an object moves on a circular path, the centripetal force varies directly as the square of the velocity and inversely as the radius of the curve. If the force is 640 lb for a velocity of 20 mi/h and radius of 5 m, find the radius for a velocity of 30 mi/h and a force of 1800 lb.
Answer: I think it's 40
Step-by-step explanation:
I don't know, I just need points. If you take the 640 and divide it by the nearest angular velocity, then square it, then divide by the radius, you get Bolivia

65÷b+8×4=20
Put the value of b=5 in equation
65÷5+8×4=20
According to BDMAS rule
13+32=20
45=20
Bring the terms on one side
45-20=25 Answer
Answer:
false
Step-by-step explanation:
use bidmas :)
ok, let's rewrite this for b = 5
65 ÷ 5 + 8 × 4 = 20
now put brackets
(65 ÷ 5) + (8 × 4) = 20
(13) + (32) = 20
13 + 32 = 45
45 ≠ 20
false
hope this helped and good luck!

Solve for x. hint:half circle.
Answer:
[tex]x = 10[/tex]
Step-by-step explanation:
Given
The attached circle
Required
Find the measure of x
From the attached image:
[tex]11x + 2[/tex] and [tex]-2 + 7x[/tex] form a semi-circle
So:
[tex]11x + 2 -2 + 7x = 180[/tex]
Collect like terms
[tex]11x + 7x = 180+ 2 -2[/tex]
[tex]18x = 180[/tex]
Solve for x
[tex]x = \frac{180}{18}[/tex]
[tex]x = 10[/tex]

A number, f is positive
Answer:
Not enough information.
Step-by-step explanation:
The National Assessment of Educational Progress (NAEP) includes a "long-term trend" study that tracks reading and mathematics skills over time, and obtains demographic information. In the 2012 study, a random sample of 9000 17-year-old students was selected.24 The NAEP sample used a multistage design, but the overall effect is quite similar to an SRS of 17-year-olds who are still in school. In the sample, 51% of students had at least one parent who was a college graduate. Estimate, with 99% confidence, the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college.
Answer:
The 99% confidence interval estimate for the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college is (0.4964, 0.5236).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Sample of 9000, 51% of students had at least one parent who was a college graduate.
This means that [tex]n = 9000, \pi = 0.51[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.51 - 2.575\sqrt{\frac{0.51*0.49}{9000}} = 0.4964[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.51 + 2.575\sqrt{\frac{0.51*0.49}{9000}} = 0.5236[/tex]
The 99% confidence interval estimate for the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college is (0.4964, 0.5236).
