Answer:
First one is 42 and the second one is 48.
Step-by-step explanation:
Start with parentheses. I'll use the first one as an example. 3 x 7 is 21. Now that the parentheses are done, multiply it by whatever's left. 21 x 2, that's 42. For the other one, 2 x 3 is 6, x 7, is 48. Have a good day :)

What is 147.5% as a decimal?
Answer:
1.475
Step-by-step explanation:
When we have a percentage and want to convert it to the decimal, we want to move the decimal 2 places to the left (away from the percentage) or divide by 100.
147.5/100 = 1.475
Solve for a: b − 2a = c
Answer:
[tex]a=-\frac{c-b}{2}[/tex]
Step-by-step explanation:
Solving for the variable [tex]a[/tex], given that :
[tex]b-2a=c[/tex]
We can first start start by subtracting [tex]b[/tex] from both sides of the equation:
[tex]-2a=c-b[/tex]
Now, we can divide both sides of the equation by the coefficient of [tex]a[/tex], which would be [tex]-2[/tex]:
[tex]a=\frac{c}{-2}-\frac{b}{-2}[/tex]
Applying the fraction rule [tex]\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}[/tex]:
[tex]a=\frac{c-b}{-2}[/tex]
Then, apply the fraction rule [tex]\frac{a}{-b} =-\frac{a}{b}[/tex]
[tex]a=-\frac{c-b}{2}[/tex]
1. The bill at a restaurant is $65.38. The waiter typically receives a 15% tip.
How much is the total bill?
Answer:
75.187 $
Step-by-step explanation:
I did it this way:
65.38$ : 100% = X : 115%
100X = 65.38 x 115
100X = 7518.7
X = 7518.7 ÷ 100
X = 75.187

In a random sample of 145 people, 112 said that they watched educational TV. Find the 93% confidence interval of the true proportion of people who watched educational TV.
Answer:
The 93% confidence interval of the true proportion of people who watched educational TV
(0.73716 , 0.80684)
Step-by-step explanation:
Step(i):-
Given sample size 'n' = 145
A random sample of 145 people, 112 said that they watched educational TV.
Sample proportion
[tex]p^{-} = \frac{112}{145} = 0.772[/tex]
Step(ii):-
The 93% confidence interval of the true proportion of people who watched educational TV
[tex](p- Z_{0.07}\sqrt{\frac{pq}{n} } , p + Z_{0.07} \sqrt{\frac{pq}{n} } )[/tex]
[tex](0.772- 1.427\sqrt{\frac{0.772X0.228}{145} } , 0.772 + 1.427 \sqrt{\frac{0.772X0.228}{145} } )[/tex]
( 0.772 - 0.03484 , 0.772 + 0.03484)
(0.73716 , 0.80684)
Final answer:-
The 93% confidence interval of the true proportion of people who watched educational TV
(0.73716 , 0.80684)

A cabinetmaker is asked to build a cabinet with dimensions of 8 inches wide by 14 inches long by 40 inches tall. He is then asked to reduce the size of the cabinet by a scale factor of 3/4. What are the new dimensions of the cabinet?
Answer:
6 inches by 10 1/2 inches by 30 inches
Step-by-step explanation: To find this answer you have to multiply the old dimensions by the scale factor which is 3/4. You would do 8 times 3/4 which is 6 inches. Then 14 inches times 3/4 which is 10 1/2. And then 40 inches times 3/4 and that answer is 30 inches. Those are the new dimensions for the cabinet.
A scuba diver was at a depth of −8012 feet. How many feet did the scuba diver ascend if the diver traveled to the surface of the ocean?
The scuba driver traveled to the sea level which is 8012 feet
what is sea level?Sea level is measured in relation to the adjacent land. Just like the ocean, the elevation of land may rise and fall over time. For example, the tremendous weight of a glacier on land pushes the land down, closer to sea level. And the sea level at the surface of the ocean is considered to be zero.
Given here, he dived to a depth -8012 feet so he has to ascend again by + 8012 feet to reach the surface of the ocean .
Hence, he traveled 8012 feet.

Answer:
2 Radical 50
Step-by-step explanation:
Now we need to reduce the 100,since 2 is not reducible its automatically goes outside the radical. To reduce the 100 we can multiply 50 times 2.You can see now that the 2 in the radical is also not reducible so that also has to go outside the radical. When you get two numbers that are alike you don't necessarily combine them but only use one of them.

Find the 37th term of the arithmetic sequence: -38,-8,22,52
Answer:
1042
Step-by-step explanation:
-38,-8,22,52
The common difference is 52 - 22 = 30
a_1 = -38
a_2 = -38 + 30
a_3 = -38 + 2 * 30
a_4 = -38 + 3 * 30 (notice that the common difference is multiplied by 1 less than the term number)
a_n = -38 + (n - 1)30 (since the term number is n, we multiply the common difference by n - 1)
a_n = -38 + 30(n - 1)
a_37 = -38 + 30(37 - 1)
a_37 = 1042
Can someone help me solve for x and y of this?
Answer:
x = 10
y = 5
Step-by-step explanation:
Since, two lines p and q are the parallel lines and FA is a transversal line intersecting these parallel lines.
ΔAOB and ΔDOC are the similar triangles.
Therefore, by the property of similar triangles, corresponding sides of the similar triangles will be proportional.
[tex]\frac{AO}{OD}= \frac{OB}{OC}[/tex]
[tex]\frac{x}{15}= \frac{8}{12}[/tex]
x = [tex]\frac{15\times 8}{12}[/tex]
x = 10
Similarly, triangles AOB and OEF will be similar.
And by the property of similar triangles,
[tex]\frac{AO}{OF}= \frac{OB}{OE}[/tex]
[tex]\frac{x}{15+y}= \frac{8}{12+4}[/tex]
[tex]\frac{10}{15+y}= \frac{8}{16}[/tex]
8(15 + y) = 160
120 + 8y = 160
8y = 160 - 120
8y = 40
y = 5

How does the graph of g(x) = 3X – 2 compare to the graph of f(x) = 3X?
The graph of g(x) is a translation of f(x) 2 units left.
The graph of g(x) is a translation of f(x) 2 units right.
O The graph of g(x) is a translation of f(x) 2 units up.
The graph of g(x) is a translation of f(x) 2 units down.
Using translation concepts, it is found that:
The graph of g(x) is a translation of f(x) 2 units down.
---------------------------------------------
Translating a function f(x) a units down is the same as finding f(x) - a.
---------------------------------------------
In this question:
[tex]f(x) = 3x[/tex][tex]g(x) = 3x - 2 = f(x) - 2[/tex]Thus, g(x) is f(x) translated 2 units down, and the correct option is:
The graph of g(x) is a translation of f(x) 2 units down.
---------------------------------------------
At the end, the graph is given, with f(x) in red and g(x) in blue.

Given the equation,
y = 1/3x - 4, what is the slope and the y-intercept?
m= 4 and b= 1/3
m= -4 and b=1/3
m= 1/3 and b= 4
m= 1/3 and b= -4
Answer:
m = 1/3 and b = - 4
Step-by-step explanation:
The equation already gives the answer as the equation is in slope-intercept form.
[tex]y = mx + b[/tex]
Where m = slope and b = y-intercept.
From the equation —
[tex]y = \frac{1}{3} x - 4 \\ m = \frac{1}{ 3} \\ b = - 4[/tex]
Therefore, our slope is 1/3 and y-intercept is - 4.

g(x) = 2x² +16x+35
(a) Write the equation in the form g (x)= a (x - h)2 + k.
Answer:
The equation g(x) = 2(x+4)² +3
(h,k) = (-4,3) and a = 2
Step-by-step explanation:
Step(i):-
Given equation g(x) = 2 x² + 16 x +35
g(x) = 2(x² +8 x ) +35
g(x) = 2(x² +2(4) (x ) +(4)² -(4)²)+35
we know that (a+b)² = a²+2ab+b²
Step(ii):-
g(x) = 2( x+4)² - 2(16) +35
⇒ g(x) = 2(x+4)² - 32 +35
⇒ g(x) = 2(x+4)² +3
comparing g(x) = a (x-h)² +k
(h,k) = (-4,3) and a = 2
Final answer:-
The equation g(x) = 2(x+4)² +3
(h,k) = (-4,3) and a = 2
