Answer:
D. 20
Step-by-step explanation:
since the given shape is a parallelogram the parallel sides' length must be equal:
2x-10 = x+30
2x-x = 30+10
x = 40
2y-10 = y+10
2y-y = 10+10
y = 20
since z = x - y
z = 40-20
z = 20
Amelia drives 10 miles in 20 minutes. If she drove three hours in total at the same rate, how far did she go?
Answer:
she went 90 miles in 3 hours
Step-by-step explanation:
in 20 minutes, she went 10 miles.
so in 1 hour, we multiply both 10 and 20 by 3
in 1 hour, Amelia drives 30 miles
we multiply this by 3,
and we get 90 miles in 3 hours :)
Determine the value of x.
Answer:
x = 4.59
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 74 = 16/ x
x tan 74 = 16
x = 16/ tan 74
x=4.58792

Solve the equation by factoring.
z2 - 6z - 27 = 0
A. z = 3 or z = 9
B. z = –3 or z = 9
C. z = –3 or z = –9
D. z = 3 or z = –9
Answer:
B
Step-by-step explanation:
z^2 - 6z - 27 = 0
(z - 9)(z+3) = 0
z - 9 = 0 z + 3 = 0
z = -3, 9
The teacher and her students are playing a game. The students take turn to say from 1 to 100 (1 student says 1 number in each turn). However, in the turn that students need to say the number which has the digit 7, they need to say "Buzz" instead. For example, if Hoa has number 17 in her turn, Hoa will say "Buzz" instead of "seventeen". How many times will the students say "Buzz" in total?

Help me with this question please‼️‼️
Explanation:
The gradient is the same as the slope
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (6-1)/(6 - (-4))
m = (6-1)/(6+4)
m = 5/10
m = 1/2
In decimal form, this becomes 0.5
A slope of 1/2 means we move up 1 and to the right 2 units each time to generate points along the diagonal line.
A positive slope goes uphill as we move to the right (due to the positive rise value).
Answer:
One way to find the gradient is using the expression :
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{y_{B} - y_{A}}{x_{B} - x_{A}}[/tex]
So [tex]m = \frac{6 - 1}{6- (-4)} =\frac{5}{10} =\frac{1}{2}[/tex]

Anybody good in math?
Answer:
im good
Step-by-step explanation:
The easiest and most time-effective way to approach this problem is to use the quadratic formula:
[tex]x=\frac{-b\pm\sqrt{ b^2-4ac}}{2a}[/tex],
where a = 2, b = -1, and c = 4. (We get this from the general quadratic: ax² + bx + c.)
When we plug in our numbers, we get [tex]x=\frac{1\pm\sqrt{1-32}}{4}[/tex] which also equals [tex]\frac{1\pm i\sqrt{31}}{4}[/tex], or the first choice!

Solve by substitoution
Answer:
x=7
y=-1
Step-by-step explanation:
x=-9y-2--------(1)
4x-3y=31
4x=31+3y
x=31/4+3/4y-------(2)
x=-9y-2=31/4+3/4y
-9y-3/4y=31/4+2
-39/4y=39/4
y=-1

Which of the following choices is the correct translation of the statement: "the length of a rectangle if the length is twice the size of the width increased by one"?
Оооо
1 = 2w - 1
I = 2w + 1
1 = 3w
None of these choices are correct.
The length of a rectangle if the length is I = 2w + 1.
What is a rectangle?
A Rectangle is a 4 sided-polygon, having all the inner angles identical to 90 ranges. the 2 aspects at each corner or vertex, meet at right angles. the alternative sides of the rectangle are identical in length which makes it specific from a square.
The area of the rectangle is = length * breath
The perimeter of the rectangle = 2(L*B)

What do the sides in a triangle add up to? I know that the inner angles of a triangle add up to 180°, but what do the sides of a triangle add up to?
Answer:
The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can't be 0 or 180 degrees, because the triangles would become straight lines.

Part 2
Set the denominator function equal to zero and solve for x to find which values to kick out of the domain.
[tex]h(x) = 0\\\\-2x^2+7 = 0\\\\7 = 2x^2\\\\2x^2 = 7\\\\x^2 = 7/2\\\\x^2 = 3.5\\\\x = \sqrt{3.5} \ \text{ or } x = -\sqrt{3.5}\\\\[/tex]
This shows that if x is equal to either of those values, then the denominator h(x) will be zero. These are the values to kick out of the domain to prevent a division by zero error. Any other value of x is valid in the domain.

Answer:
D
Step-by-step explanation:
The sides of a rhombus are congruent , then
13b - 9 = 3b + 4 ( subtract 3b from both sides )
10b - 9 = 4 ( add 9 to both sides )
10b = 13 ( divide both sides by 10 )
b = 1.3
The diagonals are perpendicular bisectors of each other , then
14a + 20 = 90 ( subtract 20 from both sides )
14a = 70 ( divide both sides by 14 )
a = 5
Thus c = a + b = 5 + 1.3 = 6.3 → D

Answer:
m=5/3
Step-by-step explanation:
Answer:
5/3 or 1 2/3
Step-by-step explanation:
First you subtract 4/3 from the left side. 23/6-4/3= 2 1/2
Then you multiply 2 on both sides, this simplifies the left side to be 3m and the right side 5.
Lastly, you divide by 3 to isolate the variable m.
And you get 5/3, which also equals 1 2/3

- 7(x + 4) - 4= - 32
Integer or fraction
Answer:
x=0
Step-by-step explanation:
- 7(x + 4) - 4= - 32
Add 4 to each side
- 7(x + 4) - 4+4= - 32+4
- 7(x + 4) = - 28
Divide by -7
- 7(x + 4) /-7= - 28/-7
x+4 = 4
Subtract 4 from each side
x+4-4 = 4-4
x=0
